ELEMENTOS DA GEOMETRIA DE UMA SUSPENSÃO VEICULAR Allnhaznentio de DireçãoELEMENTS OF THE GEOMETRY OF A VEHICLE SUSPENSION Allnhaznentio Steering

O alinhamento é especificado pelo fabricante dos veiculos a fim de oferecer uma maior eficiência de rolamento, melhor dirigibilidade e otimização do grau de esterção. Qualquer alteração que ocorra nas especificações de alinhamento, ocasionada por impacto, trepidação, compressão lateral e desgaste dos componentes da suspensão, poderá comprometer o bom comportamento do veiculo. Ou, ainda, provocar um desgaste irregular e prematuro da banda de rodagem dos pneus. Alinhamento das rodas dianteiras baseado na linha geométrica centralAlignment is specified by the vehicle manufacturer to provide higher rolling efficiency, better drivability and optimization of the degree of esterification. Any change in alignment specifications caused by impact, chatter, lateral compression and suspension component wear may compromise the vehicle's good behavior. Or cause uneven and premature wear of the tire tread. Front wheel alignment based on centerline

A convergência de cada roda dianteira é medida e ajustada usando-se como referência a linha geométrica central do veiculo. Este método foi usado por muitos anos, podendo proporcionar serviços de alinhamento satisfatórios, desde que as rodas traseiras do veiculo estejam posicionadas perfeitamente paralelas à linha geométrica central.The convergence of each front wheel is measured and adjusted using the vehicle centerline as a reference. This method has been used for many years and can provide satisfactory alignment services as long as the rear wheels of the vehicle are positioned perfectly parallel to the centerline.

No caso em que as rodas traseiras (eixo rigido ou suspensão independente), criam uma linha direcional formando um ângulo com a linha geométrica central, a geometria da direção sairá do seu ponto central e o volante ficará torto para um dos lados, quando o veiculo "rodar" em linha reta.In the event that the rear wheels (rigid axle or independent suspension) create a directional line forming an angle to the centerline, the steering geometry will come out of its center point and the steering wheel will be bent to one side when the vehicle "rotate" straight.

Alinhamento das rodas dianteiras baseado na linha direcionalFront wheel alignment based on directional line

Alinhar as rodas dianteiras baseando-se na linha direcional criada pelas rodas traseiras representa avanço considerável sobre o método anterior.Aligning the front wheels based on the directional line created by the rear wheels represents a considerable advance over the previous method.

Neste método a convergência traseira é medida (não ajustada). Com esta medição determina-se a linha direcional das rodas traseiras que é usada como referência para o ajuste das rodas dianteiras. Como resultado, na maioria dos casos, o volante ficará centrado quando o veiculo se desloca em linha reta.In this method rear convergence is measured (not adjusted). This measurement determines the directional line of the rear wheels that is used as a reference for adjusting the front wheels. As a result, in most cases the steering wheel will be centered when the vehicle travels in a straight line.

Alinhamento total nas quatro rodasFull four-wheel alignment

Alinhamento total é o serviço mais completo, a convergência individual traseira é medida e ajustada conforme as especificações do fabricante. Este ajuste faz coincidir a linha direcional das rodas traseiras com a linha geométrica central direcional. Neste caso as quatro rodas ficarão paralelas entre si e o volante centrado, teremos então o paralelismo total do veiculo.Full alignment is the most complete service, rear individual convergence is measured and adjusted to manufacturer specifications. This adjustment matches the rear wheel directional line with the center directional geometric line. In this case the four wheels will be parallel to each other and the centered steering wheel, we will then have the total parallelism of the vehicle.

ConvergênciaConvergence

Convergência, conforme ilustra a figura 1, é o ajuste das rodas direcionadas, de modo que fiquem mais fechadas na extremidade dianteira do que na traseira.Convergence, as shown in Figure 1, is the adjustment of the driven wheels so that they are closer at the front end than at the rear.

DivergênciaDivergence

Divergência, conforme ilustra a figura 2, é a condição oposta à convergência. Neste caso, as rodas estão mais abertas na extremidade dianteira do que na traseira. Se os valores especificados para a convergência das rodas estiverem alterados, a banda de rodagem dos pneus apresenta um desgaste irregular em forma de "serra", que provocará um alisamento acelerado da mesma.Divergence, as illustrated in Figure 2, is the opposite condition to convergence. In this case, the wheels are more open at the front end than at the rear. If the specified values for wheel convergence are changed, the tire tread exhibits uneven "saw" shape wear, which will accelerate the tire evenly.

A amplitude de convergência ou divergência pode ser expressa das seguintes formas:The amplitude of convergence or divergence may be expressed as follows:

• Medida Angular (em graus) relacionada à linha geométrica central do veiculo; e• Angular measurement (in degrees) related to the vehicle's central geometric line; and

• Medida Linear (em milímetros) usando como referência a borda da roda.• Linear measurement (in millimeters) by reference to wheel rim.

As figuras 3, 4 e 5 mostram, respectivamente, convergência, divergência e paralelismo entre as rodas (ângulo 0) .Figures 3, 4 and 5 show, respectively, convergence, divergence and parallelism between the wheels (angle 0).

FunçãoFunction

O objetivo é fazer com que as rodas se mantenham paralelas com a trajetória, quando o veículo está em movimento, evitando assim uma fricção lateral dos pneus com o solo, minimizando o desgaste dos mesmos.The objective is to keep the wheels parallel with the track when the vehicle is moving, thus avoiding lateral tire friction with the ground, minimizing tire wear.

O desgaste gerado por um desajuste de convergência ou divergência de 3mm, eqüivale a um arraste lateral de 2 metros por cada quilômetro percorrido. Variações na altura da suspensão podem afetar as medidas de convergência ou divergência.The wear generated by a convergence mismatch or divergence of 3mm equals a side drag of 2 meters for each kilometer traveled. Variations in suspension height may affect convergence or divergence measurements.

Divergência nas CurvasCurve Divergence

Para fazer uma curva, a roda interna (com relação a traseira ) deverá esterçar mais do que a externa, a fim de produzir a necessária divergência para efetuar esta curva com segurança. Após efetuar a curva, esta situação de divergência deve cessar, retornando ao paralelismo especificado. Se o ângulo de giro especificado para uma roda interna estiver fora das recomendações, todos os pneus do veiculo sofrerão um desgaste excessivo nas curvas, em conseqüência do arrasto a que são submetidos.To make a turn, the inner wheel (relative to the rear) must steer more than the outer wheel to produce the necessary divergence to make this turn safely. After making the curve, this divergence situation must cease, returning to the specified parallelism. If the specified turning angle for an inner wheel is out of range, all vehicle tires will wear excessively on the corners as a result of the drag they are subjected to.

Diferenças superiores a IM graus lado a lado no ângulo de divergência em curvas indicam uma torção ou defeito nos braços de direção do veiculo.Differences greater than IM degrees side by side in the divergence angle in curves indicate a twist or defect in the vehicle's steering arms.

Durante uma curva, a roda do lado interno descreve uma curvatura menor que a do lado externo, portanto, a roda interna deve inclinar um pouco mais do que a externa, a fim de evitar atrito excessivo dos pneus com o solo.During a corner, the inner wheel describes a smaller curvature than the outer wheel, so the inner wheel should tilt slightly more than the outer wheel to avoid excessive tire friction with the ground.

CasterCaster

Conforme ilustra a figura 6, caster é o ângulo de inclinação para frente (negativo) ou para trás (positivo) do pino mestre ou braço de suporte do eixo na parte superior, com relação a um plano vertical. 0 caster é responsável pela estabilidade direcional do veiculo. Pouco ou nenhum caster ocasionará um bamboleio na roda, resultando em desgaste acentuado em pontos localizados da banda de rodagem de um pneu.As shown in Figure 6, caster is the forward (negative) or backward (positive) tilt angle of the kingpin or shaft support arm at the top relative to a vertical plane. The caster is responsible for the directional stability of the vehicle. Little or no caster will cause the wheel to wobble, resulting in marked wear on localized points of a tire tread.

O caster desigual faz com que a roda puxe para um lado, provocando um desgaste irregular da banda de rodagem do pneu. 0 caster excessivo originará um desgaste total e prematuro da banda de rodagem do pneu.The uneven caster causes the wheel to pull to one side, causing uneven tire tread wear. Excessive caster will cause premature full wear of the tire tread.

Na figura 7 temos:In figure 7 we have:

• Positivo - quando a inclinação do eixo de giro é para a frente;• Positive - when the inclination of the pivot axis is forward;

• Negativo - quando a inclinação do eixo de giro é para trás; e• Negative - when the inclination of the turning axis is backwards; and

· Zero - quando o eixo de giro está na vertical.· Zero - when the pivot axis is vertical.

FunçãoFunction

Proporcionar estabilidade direcional.Provide directional stability.

O caster, quando positivo, projetando para frente o eixo de giro, estabelece o ponto de carga para frente do ponto de contato da roda com o solo. Com isso, as rodas tendem a manter-se alinhadas para frente, impondo ao veiculo uma trajetória em linha reta. O caster apesar de ser um ângulo critico para o controle do veiculo, não influencia no desgaste dos pneus.The caster, when positive, projecting the swing axle forward, establishes the forward loading point of the wheel contact point with the ground. As a result, the wheels tend to be aligned straight ahead, imposing a straight trajectory on the vehicle. Although the caster is a critical angle for vehicle control, it does not influence tire wear.

Os efeitos de um caster fora das especificações são os seguintes:The effects of an off-spec caster are as follows:

Quando insuficienteWhen insufficient

• Reduz a estabilidade direcional em alta velocidade; e• Reduces high-speed directional stability; and

• Reduz o esforço direcional requerido em baixa velocidade.• Reduces the directional effort required at low speed.

Quando excessivoWhen excessive

• Aumenta a estabilidade direcional em alta velocidade;• Increases directional stability at high speed;

• Aumenta o esforço direcional requerido em baixa velocidade; e• Increases the directional effort required at low speed; and

• Pode causar vibrações laterais em alta velocidade.• May cause side vibrations at high speed.

Diferente lado a ladoDifferent side by side

• Pode causar tendências no veiculo de "puxar" para um dos lados e pode causar problemas em frenagens violentas; e• May cause vehicle pull tendencies to one side and may cause problems with violent braking; and

• A máxima diferença permissível lado a lado é de ½ grau.• The maximum allowable difference side by side is ½ degree.

CamberCamber

O camber, conforme exemplificado na figura 8 é determinado pela inclinação da parte superior da roda, para dentro ou para fora do veiculo, em relação a um plano vertical. A cambagem pode ser positiva ou negativa. A cambagem excessiva provoca um desgaste mais acentuado no ombro do pneu. Se o camber for positivo, o desgaste será no ombro externo; se for negativo, o desgaste será no ombro interno do pneu.The camber as exemplified in Figure 8 is determined by tilting the top of the wheel into or out of the vehicle relative to a vertical plane. The camber can be positive or negative. Excessive camber causes more wear on the tire shoulder. If the camber is positive, the wear will be on the outer shoulder; If negative, wear will be on the inner shoulder of the tire.

FunçãoFunction

A função do camber é distribuir o peso do veiculo sobre a banda de rodagem dos pneus de maneira uniforme, evitando desgaste irregular dos mesmos. Desgaste excessivo nos "ombros" dos pneus são geralmente atribuídos a regulagens incorretas de camber.The function of the camber is to distribute the weight of the vehicle on the tire tread evenly, avoiding uneven tire wear. Excessive tire shoulder wear is generally attributed to incorrect camber adjustments.

Camber Negativo (fig. 9) Ocasiona desgaste prematuro no ombro interno do pneu.Camber Negative (Fig. 9) Causes premature wear on the inner shoulder of the tire.

Projeta o ponto de aplicação do peso do veiculo para a extremidade do eixo da roda, gerando um efeito de alavanca que causa instabilidade vertical e fadiga, tanto no eixo quanto nos demais componentes da suspensão.Designs the point of application of vehicle weight to the end of the wheel axle, generating a leverage effect that causes vertical instability and fatigue on both the axle and other suspension components.

Camber Positivo (fig.10)Positive Camber (Fig.10)

Ocasiona desgaste prematuro no ombro externo dos pneus.It causes premature wear on the outer shoulder of the tires.

Projeta o ponto de aplicação do peso do veiculo para a parte interna do eixo da roda, diminuindo o efeito de alavanca e, consequentemente, aumentando a estabilidade vertical do veiculo.Designs the point of application of the vehicle weight to the inside of the wheel axle, decreasing the leverage effect and thereby increasing the vertical stability of the vehicle.

Camber Desigual (fig. 11)Camber Desigual (Fig. 11)

Quando não houver especificações do fabricante, deve-se tolerar uma diferença máxima de ^ graus de camber lado a lado. O veiculo tende a "puxar para o lado da roda que estiver com o ajuste de camber mais positivo.When not specified by the manufacturer, a maximum difference of ^ degrees camber side by side shall be tolerated. The vehicle tends to "pull to the side of the wheel that has the most positive camber setting.

KPI/SAIKPI / SAI

O KPI/SAI, tal como mostra a figura 12, é o ângulo formado pela linha que atravessa o eixo de giro e a vertical natural, visto a roda de frente.The KPI / SAI, as shown in Figure 12, is the angle formed by the line crossing the pivot axis and the natural vertical, viewed from the front wheel.

O KPI/SAI é um ângulo que não se mede diretamente, mas sim com um giro preestabelecido das rodas dianteiras. Obtêm-se mais precisão se o giro for simétrico com relação a linha direcional do eixo traseiro.The KPI / SAI is an angle that is not measured directly, but with a pre-set front wheel turn. More precision is obtained if the rotation is symmetrical with respect to the rear axle directional line.

Função O KPI/SAI contribui com a estabilidade da direção, pois impõe às rodas uma tendência de manter uma trajetória reta e diminui os efeitos dos obstáculos no volante.Function The KPI / SAI contributes to steering stability by imposing a tendency on wheels to maintain a straight track and reducing the effects of obstacles on the steering wheel.

O ângulo KPI/SAI permite que se usem ângulos deThe KPI / SAI angle allows you to use angles of

caster menos positivos para facilitar a dirigibilidade do veiculo sem alterar a estabilidade direcional.less positive caster to facilitate vehicle handling without changing directional stability.

Ângulo InclusoIncluded Angle

Tal como mostra a figura 13, ângulo Incluso é a soma dos ângulos KPI/SAI e camber. É formado pelo eixo de giro e o eixo geométrico da roda. A diferença máxima permissivel de ângulo incluso de uma roda em relação a outra é de 1,5 graus.As shown in figure 13, Included angle is the sum of the angles KPI / SAI and camber. It is formed by the rotating axis and the geometric axis of the wheel. The maximum permissible difference in inclined angle of one wheel relative to another is 1.5 degrees.

Quando se altera o ângulo de camber, o ângulo incluso também é alterado.When you change the camber angle, the included angle also changes.

Set BackSet back

O Set Back (SB) , exemplificado na figura 14, corresponde a diferença coaxial dos eixos, onde (Ll) é a linha geométrica central. Representa o "atraso" de uma das rodas dianteiras, ou seja, a distância que uma roda está "atrasada" em relação a outra.The Set Back (SB), exemplified in Figure 14, corresponds to the coaxial difference of the axes, where (Ll) is the central geometric line. Represents the "delay" of one of the front wheels, ie the distance that one wheel is "behind" the other.

O ângulo de set back, tal como mostra a figura 15, é formado entre a linha geométrica central (Ll) e a perpendicular da linha do eixo dianteiro (L2) (medido em graus).The set back angle, as shown in Figure 15, is formed between the center geometric line (L1) and the perpendicular to the front axle line (L2) (measured in degrees).

Considera-se o (9SB) set back positivo, quando a roda esquerda está em frente da direita, e negativo quando a roda direita está em frente da esquerda.Positive (9SB) set back is considered when the left wheel is in front of the right, and negative when the right wheel is in front of the left.

Efeitos do Set BackSet Back Effects

Ângulos de set back superiores a +/- ¾ graus podem fazer com que o veículo puxe para o lado da roda atrasada, bem como geral instabilidade durante as frenagens.Set back angles greater than +/- ¾ degrees may cause the vehicle to pull to the rear wheel side as well as general instability during braking.

Raio de giroTurning radius

O raio de giro, tal como exemplificado na figura 16, é a distância entre o ponto de contato do pneu com o solo e a projeção do eixo direcional.The turning radius, as exemplified in Figure 16, is the distance between the point of contact of the tire with the ground and the steering axle projection.

Paralelismo totalTotal parallelism

O paralelismo total está exemplificado nas figuras 17 e 18, onde Ll é a linha geométrica central,θ é o ângulo direcional do eixo traseiro e L2 é a linha direcional do eixo traseiro. O paralelismo total significa que as quatro rodas estão alinhadas entre si, estas por sua vez, paralelas à linha central do veículo e o volante centrado. Esta situação é considerada ideal para a condução de um veículo.Total parallelism is exemplified in Figures 17 and 18, where Ll is the center geometric line, θ is the rear axle directional angle, and L2 is the rear axle directional line. Full parallelism means that the four wheels are aligned with each other, which in turn is parallel to the vehicle's center line and centered steering wheel. This situation is considered ideal for driving a vehicle.

Calibration fault detector and automatic calibrator Considerações sobre o estado da técnica.Calibration fault detector and automatic calibrator State of the art considerations.

De todas as tecnologias criadas para tais tipos de medições veiculares, destacam-se aquelas baseadas em sistemas ópticos, nos quais os ângulos são medidos através de fontes de luz infravermelho que incidem em um goniômetro, que concentra o feixe de luz sobre um sensor tipo CCD. São utilizados também sensores de inclinação (através de pêndulo ou liquido) para se medir alguns ângulos, tais como: caster e inclinação das rodas. A Figura 19 é uma ilustração simples desse sistema. Estas cabeças são fixadas através de uma garra de fixação em cada uma das rodas do veiculo. Os ângulos específicos de cada roda são medidos através do inclinômetro. Já os ângulos entre as rodas são medidos através do sistema óptico com goniômetro e sensor CCD.Of all the technologies created for such types of vehicle measurements, those based on optical systems stand out, in which angles are measured through infrared light sources that focus on a goniometer, which concentrates the light beam on a CCD sensor. . Tilt sensors (pendulum or liquid) are also used to measure some angles such as caster and wheel tilt. Figure 19 is a simple illustration of this system. These heads are fixed by means of a clamping jaw on each of the vehicle's wheels. The specific angles of each wheel are measured using the inclinometer. Already the angles between the wheels are measured through the optical system with goniometer and CCD sensor.

Ocorre que estes sistemas são precisos, porém bastante delicados e exigem investimentos consideráveis, o que os torna limitantes, pois, esse nível de investimento restringe o número de usuários com capital modesto para prestar tal tipo de serviço. 0 fato de serem delicados exige calibrações periódicas que são realizadas por técnicos especializados. Dificilmente o usuário tem como verificar se o instrumento está calibrado ou não. Muitas vezes ele só percebe que existe um problema de calibração quando o veículo apresenta problemas (sintomas conforme descrito anteriormente) após a realização do serviço.It happens that these systems are precise but quite delicate and require considerable investments, which makes them limiting, because this level of investment restricts the number of users with modest capital to provide such services. The fact that they are delicate requires periodic calibrations that are performed by skilled technicians. The user can hardly verify if the instrument is calibrated or not. Often he only realizes that there is a calibration problem when the vehicle has problems (symptoms as described above) after the service is performed.

Objetivos da Invenção.Objectives of the Invention.

O principal objetivo da invenção é oferecer um novo conceito para leitura dos ângulos, logicamente em substituição aos instrumentos de medição através de fontes de luz infravermelho, sendo que, para tanto, foram criadas quatro cabeças de leitura, igualmente equipadas com recursos eletrônicos, de modo que cada uma delas possa ter preferivelmente três giroscópios eletrônicos para detecção dos ângulos XYZ. Cada cabeça de leitura inclui recursos para ser fixada no centro da roda do veiculo e, assim, usando-se 4 objetos com 3 giroscópios cada (3 coordenadas) podemos obter os ângulos entre os 4 objetos em 3 coordenadas.The main object of the invention is to provide a new concept for reading angles, logically replacing the measuring instruments by infrared light sources. To this end, four reading heads, equally equipped with electronic resources, have been created. that each of them may preferably have three electronic gyros for XYZ angle detection. Each read head includes features to be fixed to the center of the vehicle wheel, so using 4 objects with 3 gyros each (3 coordinates) we can get the angles between the 4 objects in 3 coordinates.

Outro objetivo da invenção é prever uma base de calibragem que funciona como gabarito permanente para calibragem automática das referidas cabeças de medição após o seu uso, ou seja, num momento inicial as cabeças de leitura ficam no gabarito onde todos os ângulos serão iguais a zero. Em um segundo momento as referidas cabeças são fixadas às rodas do veiculo e, com isso, todos os ângulos serão calculados em cada um dos eixos e em cada uma das cabeças.Another object of the invention is to provide a calibration base that acts as a permanent template for automatic calibration of said measuring heads after use, that is, at an initial moment the reading heads are in the template where all angles will be equal to zero. In a second moment, the said heads are fixed to the wheels of the vehicle and, as a result, all angles will be calculated on each axle and on each head.

Outro objetivo da invenção é a concretização de um equipamento com custo substancialmente reduzido, consequentemente, o investimento é menor e adequado para aqueles profissionais do ramo.Another object of the invention is the embodiment of a substantially reduced cost equipment, hence the investment is smaller and suitable for those skilled in the art.

Outro objetivo da invenção é a concretização de um equipamento que dispensa calibrações periódicas realizadas por um técnico especializado, pois, considerando-se que as cabeças de leitura sempre voltam ao gabarito após cada medição, podemos dizer que o sistema é autocalibrável, o que reduz ainda mais o seu custo.Another object of the invention is the realization of equipment that does not require periodic calibrations performed by a specialized technician, since, considering that the reading heads always return to the template after each measurement, we can say that the system is self-calibrating, which further reduces Plus your cost.

Também é objetivo da invenção a concretização de um equipamento funcional que, do ponto de vista dos usuários, o sistema não requer mudanças importantes no uso em relação aos sistemas tradicionais, ou seja, aqueles que já utilizam sistemas tradicionais não precisarão aprender coisas novas para usar o novo produto.It is also an object of the invention to realize functional equipment which, from the users' point of view, the system does not require major changes in use compared to traditional systems, ie those who already use traditional systems will not need to learn new things to use The new product.

Vantajosamente na presente invenção as cabeças serão menores e mais leves que os sistemas tradicionais e, portanto, menos suscetível a quebras causadas por quedas.Advantageously in the present invention the heads will be smaller and lighter than traditional systems and therefore less susceptible to breakage caused by falls.

Descrição detalhada da invenção. De acordo com estas ilustrações e em seus pormenores, a presente Invenção, APERFEIÇOAMENTO EM APARELHO PARA MEDIÇÃO DOS ELEMENTOS DE GEOMETRIA DE UMA SUSPENSÃO VEICULAR, está caracterizada por utilizar giroscópios eletrônicos para a medição dos ângulos, pois, como se sabe, os giroscópios são instrumentos cujo funcionamento é baseado em: conservação do momento angular em direção e sentido; momento inercial; e movimento de precessão.Detailed description of the invention. In accordance with these illustrations and their details, the present invention, apparatus for measuring the geometrical elements of a vehicle suspension, is characterized by the use of electronic gyros for measuring angles, as gyros are known to be instruments. whose operation is based on: conservation of angular momentum in direction and direction; inertial moment; and precession movement.

A figura 20 é uma ilustração esquemática para exemplificar o funcionamento de um giroscópio eletrônico (11), pois atualmente existem chips que são giroscópios eletrônicos e funcionam baseados no Principio de Coriolis. Basicamente estes circuitos geram uma tensão na saida que é diretamente proporcional à velocidade angular do seu eixo principal (Z).Figure 20 is a schematic illustration to exemplify the operation of an electronic gyroscope (11), as there are currently chips that are electronic gyros and function based on the Coriolis Principle. Basically these circuits generate an output voltage that is directly proportional to the angular velocity of their main axis (Z).

Desta maneira, conforme exemplificado na figura 21, considerando-se um ângulo θ inicialmente igual a zero (referencia fixa) é possível calcular o valor do ângulo θ integrando-se ω no tempo, ou seja, Θ= J Qdt.Thus, as exemplified in Figure 21, considering an angle θ initially equal to zero (fixed reference), it is possible to calculate the value of angle θ by integrating ω in time, ie Θ = J Qdt.

Desta maneira, podemos ter um circuito para calcular esta integral em tempo real, onde podemos obter o valor de θ em um determinado tempo tm, onde tm é o tempo que define a nova posição do chip no qual se quer obter o ângulo Θ.Thus, we can have a circuit to calculate this integral in real time, where we can get the value of θ at a given time tm, where tm is the time that defines the new position of the chip in which the angle Θ is to be obtained.

Conforme exemplificado na figura 22, também é possível fixar em um único objeto dois ou três destes chips ou giroscópios eletrônicos (11), com eixos em 3 coordenadas cartesianas, consequentemente, torna-se possível medir o deslocamento angular do objeto em 2 ou 3 eixos diferentes e eixos perpendiculares entre si.As shown in Figure 22, it is also possible to fix two or three of these electronic chips or gyros (11) on a single object, with axes in 3 Cartesian coordinates, therefore, it is possible to measure the angular displacement of the object in 2 or 3 axes. different and perpendicular axes to each other.

Levando-se em consideração também a figura 23, utilizando-se um gabarito capaz de alinhar dois ou mais objetos com estes (3 eixos), onde podemos determinar que os ângulos iniciais são todos iguais e iguais a zero, e depois deslocamos e fixamos estes objetos em outra posição (tm) temos os respectivos ângulos de deslocamento em relação ao gabarito, conforme exemplificado na figura 23, onde é ilustrado apenas dois objetos com um giroscópio cada. Neste caso o ângulo entre OBl e 0B2 será Θ1 + Θ2.Considering also the figure 23, using a template capable of aligning two or more objects with these (3 axes), where we can determine that the initial angles are all equal and equal to zero, and then we move and fix these Objects in another position (tm) have their respective angles of displacement relative to the template, as exemplified in Figure 23, where only two objects with a gyroscope are illustrated. In this case the angle between OBl and 0B2 will be Θ1 + Θ2.

Conforme exemplificado na figura 24, adotando-se o uso de 4 objetos, cada qual com 3 giroscópios (3 coordenadas). Nessa condição, é possível obter os ângulos entre os 4 objetos em 3 coordenadas na posição de medida (t=tm), consequentemente, esta metodologia aplica-se para a medição dos elementos de geometria de uma suspensão veicular.As shown in figure 24, using 4 objects, each with 3 gyros (3 coordinates). In this condition, it is possible to obtain the angles between the 4 objects in 3 coordinates at the measurement position (t = tm), consequently, this methodology applies to the measurement of the geometry elements of a vehicle suspension.

Assim, levando-se em consideração a figura 25, resumidamente, num momento inicial (t=0) os objetos ficam no gabarito onde todos os ângulos serão iguais a zero. Em um segundo momento (t=tm) os objetos são fixados às rodas do veículo, como na figura 24. Então todos os ângulos serão calculados através da integral entre O e tm em cada um dos eixos e em cada um dos obj etos.Thus, taking into consideration Figure 25, briefly, at an initial moment (t = 0) the objects are in the template where all angles will be equal to zero. In a second moment (t = tm) the objects are fixed to the wheels of the vehicle, as in figure 24. Then all angles will be calculated by the integral between 0 and tm on each axle and on each object.

Adotando-se a tecnologia acima sumariamente explicitada, a presente invenção está caracterizada pelo fato de compreender, tal como ilustram as figuras 25 e 26, uma base de calibragem (1) que, por um lado, está interligada eletronicamente com um computador usual (2) e, por outro lado, inclui meios para acoplamento/desacoplamento e interligação eletrônica com quatro cabeças de medição (3), sendo uma cabeça dianteira esquerda DE (a), uma cabeça dianteira direita DD (b) , uma cabeça traseira esquerda TE (c) e uma cabeça traseira direita TD (d) , ficando tais elementos interligados conforme o diagrama da figura 26.Adopting the aforementioned technology, the present invention is characterized in that it comprises, as illustrated in Figures 25 and 26, a calibration base (1) which, on the one hand, is electronically interconnected with a standard computer (2). ) and, on the other hand, includes coupling / uncoupling means and electronic interconnection with four measuring heads (3), one left front head DE (a), one right front head DD (b), one left rear head TE ( c) and a right rear head TD (d), such elements being interconnected according to the diagram of figure 26.

A base de calibragem (1) é o concentrador do sistema. Nela é feita a referência inicial, alimentação ou re-carga das cabeças (3), controla os processos que estão ocorrendo no sistema, coordena as interfaces com as cabeças e com o computador. Para tanto, tem seu próprio circuito eletrônico, cuja arquitetura compreende, tal como mostra o diagrama em blocos da figura 27, um microcontrolador (4) que, além da correspondente fonte de alimentação (5), também têm interligações (6) e (7 ou 8), a primeira com o computador (2), enquanto as outras duas são de comunicação com as cabeças (3abcd), as quais, opcionalmente, pode ser com ou sem fio. Com fio do tipo Serial RS232, USB, RS485, CAN ou outra compatível com o sistema.

3° passo: retiram-se as cabeças (3) da base de calibragem (1) e insere as mesmas nas respectivas garras (23) que estão presas às rodas do veiculo. Após a cabeça ser retirada do gabarito, o sistema eletrônico começa a calcular os ângulos dos 3 eixos e transmite/mostra no display as informações dos ângul os ca Iculados ao longo do tempo.Step 3: Remove the heads (3) from the calibration base (1) and insert them into the respective claws (23) attached to the vehicle wheels. After the head is removed from the template, the electronics starts calculating the angles of the 3 axes and transmits / displays the calculated angle information over time.

4° passo: através das informações do display, o operador deverá nivelar a cabeça e travar o eixo do rolamento através do manipulo (21) . Nesta situação, o aparelho já mostra as medidas dos ângulos válidas.Step 4: Through the display information, the operator should level the head and lock the bearing shaft through the handle (21).
