É em especial apropriado para ser usado nos bogias extremos e intermédios dos carros elêctricos para a circulação urbana, onde se deseja facilitar o acesso e a saída às crianças, pessoas idosas e deficientes.It is especially suitable for use in the extreme and intermediate bogies of electric cars for urban circulation, where it is desired to facilitate access and egress for children, elderly and disabled people.

Até muito recentemente, os bogias motores dos carros elêctricos suportavam na sua parte central o conjunto dos órgãos que constituem a cadeia cinemática, motor único ou duplo, acoplamentos, redutores, discos de travão. Devido ao espaço que eles ocupam, era-se obrigado a colocar o pavimento da caixa a pelo menos 850 mm acima do carril, na direcção dos bogias motores.Until very recently, the electric bogies of electric cars supported in their central part the set of organs that make up the kinematic chain, single or double motor, couplings, reducers, brake discs. Due to the space they occupy, it was obliged to place the floor of the box at least 850 mm above the rail, in the direction of the motor bogies.

Foram recentemente propostos bogias que permitemRecently bogies have been proposed that allow

-2descer o pavimento da caixa, também por cima dos bogias motores, mas recorrendo a soluções técnicas complexas, ou bogias com um só eixo, cujas rodas se orientam segundo um princípio próximo do das rodas dos automóveis, ou bogias com dois eixos, que não têm movimentos verticais relativamente à caixa, e de que certos órgãos de transmissão se dispõem por baixo destes, ou bogias de dois eixos unicamente utilizáveis como bogia intermédio sob um pavimento de inter-circulação.-2crease the floor of the box, also over the motor bogies, but using complex technical solutions, or bogies with a single axle, whose wheels are oriented according to a principle similar to that of automobile wheels, or bogies with two axles, which do not they have vertical movements in relation to the box, and that certain transmission elements are located below them, or two-axis bogies only usable as an intermediate bogie under an inter-circulation floor.

A presente invenção tem por objecto proporcionar um bogia de veículo ferroviário com um espaço ocupado vertical suficientemente pequeno para se adaptar a uma caixa de pavimento baixo, por exemplo a cerca de 350 mm acima dos carris, apre sentando no entanto uma estrutura tão simples como a dos bogias clássicos com um espaço ocupado vertical importante.The object of the present invention is to provide a railroad vehicle series with a vertical footprint small enough to fit into a low-floor box, for example about 350 mm above the rails, yet presenting a structure as simple as classic bogies with an important vertical footprint.

O bogia segundo a presente invenção ê caracterizado por compreender dois motores, e acoplamentos, redutores e discos de travão, dispostos lateralmente, de um lado e do outro, no exterior das rodas de rolamento, accionando cada motor as duas rodas de um mesmo eixo.The bogie according to the present invention is characterized by comprising two motors, and couplings, reducers and brake discs, arranged laterally, on one side and on the other, outside the rolling wheels, each motor driving the two wheels of the same axle.

referido bogia apresenta além disso pelo menos uma das características seguintes:said bogia also has at least one of the following characteristics:

- Os seus eixos são fixos e as suas rodas independen tes em rotação, e ligadas por um diferencial mecânico.- Its axles are fixed and its wheels independent in rotation, and connected by a mechanical differential.

- Os seus eixos são rotativos e as suas rodas ligadas em rotação.- Its axles are rotatable and its wheels connected in rotation.

- Os discos de travão estão dispostos em veios de saída dos motores.- The brake discs are arranged on the engine output shafts.

- Os discos de travão estão colocados em veios das rodas de rolamento, fora dos planos formados por estas.- The brake discs are placed in the shafts of the rolling wheels, outside the planes formed by them.

-3- Estes eixos são orientáveis.-3- These axes are orientable.

Descrevem-se a seguir, a título de exemplos e com referência ãs figuras do desenho anexo, um bogia motor para carro eléctrico conhecido e um bogia motor para carro eléctri co segundo a presente invenção.An example of a well-known electric car engine and an electric car engine according to the present invention are described below by way of example and with reference to the figures in the accompanying drawing.

A fig. 1 representa, em perspectiva, um bogia motor conhecido, com motor suportado pelo chassis do bogia.Fig. 1 represents, in perspective, a well-known bogia engine, with an engine supported by the bogia chassis.

A fig. 2 representa em perspectiva um bogia motor segundo a presente invenção, de eixos rotativos e rodas ligadas em rotação.Fig. 2 represents in perspective a motor shaft according to the present invention, with rotary axles and wheels connected in rotation.

Na fig. 1, o bogia compreende uma travessa de carga (1), que suporta a caixa por intermédio de uma coroa de esferas de tipo conhecido, não representada. A travessa é solidária com dois blocos laterais (IA) e (1B), ligados por sua vez a suspensões secundárias de tipo conhecido, tais como (2) e (3), por exemplo em sanduíche, de placas metálicas e de placas de um material elastomérico.In fig. 1, the bogia comprises a load beam (1), which supports the box by means of a crown of balls of known type, not shown. The crosspiece is attached to two side blocks (IA) and (1B), connected in turn to secondary suspensions of known type, such as (2) and (3), for example in sandwich, metal plates and plates of a elastomeric material.

As suspensões tais como (2) e (3) estão ligadas a placas laterais verticais tais como (2A) e (3A) solidárias com longarinas longitudinais (4) e (5) do bogia que formam o chassis deste último. As extremidades destas longarinas estão elevadas em relação ã sua parte central e vão assentar, por suspensões primárias, tais como (6) e (7), em caixas de eixos, tais como (8) e (9). Estas estão ligadas aos eixos móveis (10) e (11) que levam as rodas (12) , (13) , (14) e (15) .The suspensions such as (2) and (3) are connected to vertical side plates such as (2A) and (3A) attached to longitudinal side members (4) and (5) of the bogia that form the chassis of the latter. The ends of these stringers are raised in relation to their central part and will rest, by primary suspensions, such as (6) and (7), in axle boxes, such as (8) and (9). These are connected to the movable axles (10) and (11) that carry the wheels (12), (13), (14) and (15).

motor único (16) está suspenso no chassis do bogia. Ele está ligado por acoplamentos (17) e (18) aos redutores (19) e (20) que transmitem a rotação do motor, após desmultiplicação, aos eixos (10) e (11).single engine (16) is suspended on the bogia's chassis. It is connected by couplings (17) and (18) to the reducers (19) and (20) that transmit the motor rotation, after gearing, to the axes (10) and (11).

-4Discos de travão, tais como (21), providos de estri_ bos, tais como (22), são suportados por estes estribos.-4Brake disks, such as (21), provided with struts, such as (22), are supported by these stirrups.

Compreender-se-ã que a posição central do motor (16) e dos redutores (19) e (20) não permite dar ao carro eléctrico um pavimento baixo, pelo menos por cima do bogia.It will be understood that the central position of the motor (16) and the reducers (19) and (20) does not allow the electric car to be given a low floor, at least above the bogia.

No bogia segundo a presente invenção, representado na fig.2, a travessa de carga (31) que suporta a caixa do veículo por intermédio de uma coroa de esferas, não representada, está ligada pelas suspensões secundárias, tais como (32) e (33) (formadas por placas metálicas e placas de elastómeros em sanduíche), ao chassis (34) do bogia. Este ultimo estã, por sua vez, suportado pelos eixos (39) e (40) por intermédio das suspensões primárias (35), (35A), (36), (36A), (37), (37A),(38), (38A). Estes veios suportam nas suas extremidades as rodas de rolamento (41), (42), (43) e (44).According to the present invention, shown in fig.2, the load beam (31) that supports the vehicle body by means of a crown of balls, not shown, is connected by the secondary suspensions, such as (32) and ( 33) (formed by metallic plates and sandwich elastomeric plates), to the bogia chassis (34). The latter are, in turn, supported by the axles (39) and (40) through the primary suspensions (35), (35A), (36), (36A), (37), (37A), (38) , (38A). These shafts support the rolling wheels (41), (42), (43) and (44) at their ends.

Os motores (45) e (46) suspensos no chassis do bogia estão dispostos lateralmente, sendo os seus eixos exteriores aos planos longitudinais das rodas. Estes motores estão ligados por acoplamentos (47), (48) aos redutores (51), (52), semi-suspensos no chassis do bogia, e também exteriores aos planos das rodas que atacam os eixos destas. Cada motor acciona portanto as duas rodas de um mesmo eixo. Isso traduz-se, na versão clássica, por eixos rotativos nos quais se fixam as rodas de rolamento e, numa versão mais elaborada, por veios fixos em rotação nos quais rodam as rodas de rolamento ligadas uma à outra por um diferencial mecânico de tipo automóvel (as rodas são então independentes em rotação).The motors (45) and (46) suspended on the bogia's chassis are arranged laterally, their axles being external to the longitudinal planes of the wheels. These motors are connected by couplings (47), (48) to the reducers (51), (52), semi-suspended on the bogia's chassis, and also outside the plane of the wheels that attack the axles of these. Each motor therefore drives the two wheels on the same axle. This is translated, in the classic version, by rotating axles on which the rolling wheels are fixed and, in a more elaborate version, by fixed rotating shafts on which the rolling wheels connected to each other rotate by a car-type mechanical differential. (the wheels are then independent in rotation).

Os discos de travão, tais como (53) £ o disco ligado ao eixo (40) não é visível J estão dispostos nos veios dasThe brake discs, such as (53) £ the disc connected to the axle (40) are not visible J are arranged on the shafts of the

-5rodas de rolamento exteriores a estas formados pelas partes dos eixos exteriores ãs rodas, em oposição aos redutores. Os seus estribos (55) e (56) estão fixados no chassis do bogia /-5 rolling wheels outside these formed by parts of the axles outside the wheels, as opposed to reducers. Its stirrups (55) and (56) are attached to the bogia /

(34) .(34).

Uma outra variante consiste em dispor os discos de travão providos dos seus estribos nos veios dos motores. Os seus estribos estão então solidários com os cárteres dos motores ou com os cárteres dos redutores.Another variant is to place the brake discs provided with their stirrups on the engine shafts. Their stirrups are then attached to the engine casings or the gear units.

A disposição exterior dos motores, acoplamentos, redutores e discos de travão, lateralmente em relação aos pia nos das rodas de rolamento, permite dispor a caixa muito mais próxima do plano dos eixos e portanto obter um pavimento da caixa baixo, por exemplo a cerca de 350 mm acima dos carris.The external arrangement of the motors, couplings, reducers and brake discs, laterally in relation to the sinks of the rolling wheels, allows the box to be placed much closer to the plane of the axles and therefore to obtain a floor of the low box, for example about 350 mm above the rails.
