Description
Technical field
The invention belongs to vehicle suspension technical field, can be used for various wheeled cars; Be specially adapted to hydro pneumatic suspension or the air suspension of high maneuverability overland vehicle.
Background technology
Conventionally there is no air suspension or the hydro pneumatic suspension of the four wheeler of height control system, its air bellow or hydro-pneumatic spring are all the independent mutual disconnected systems of four-wheel.Independently suspension system of this four-wheel, while travelling on rough road surface, each wheel load is inhomogeneous, and vehicle body will be subject to very large torque load.And be all 3 independent controls conventionally with four-wheel automobile hydro pneumatic suspension or the air suspension of height control system; There is a pair of left and right elastic element (front axle or rear axle) to be subject to same height-control valve control.Another axle is independent control.The excessive inclination of vehicle body when turning, this connecting pipeline that is subject to same height-control valve control is all very thin, and " flow regulating valve " of a certain amount of hole dimension be housed.The vehicle of this structure, while travelling on rough road surface, each wheel load is very inhomogeneous, and vehicle body also will be subject to very large torque load.
The air suspension of multiple-axle vehicle or hydro pneumatic suspension, while travelling on rough road surface, each wheel load is more inhomogeneous, not only has horizontal wheel load unbalance loading, also has longitudinal wheel load unbalance loading; Vehicle body is not only subject to additional torque load, but also can be subject to concentrated additional bending moment.This technology is for the problems referred to above, by each take turns be suitably coupled additional torsion and the flexural load of eliminating vehicle body with flow control, improved ride comfort, made each load uniformization of taking turns, improved traction.
Summary of the invention
The minimizing of supporting constraint that the present invention relates to " intend triangle supporting " and " intending rhombus supports " that many wheels suspension that applicant proposes is coupled is coupled principle.Its main points are as follows:
One, the feature that various forms (non-being coupled) vehicle wheel load distributes:
1, three-wheeled vehicle: static load wheel load depends on the position of car load barycenter completely; In the situation that car load barycenter is not high, almost have nothing to do with the concavo-convex of road surface.While travelling on uneven road surface, vehicle body does not bear torque load, and the static load of its wheel load distributes and almost has nothing to do with the concavo-convex of road surface.Shortcoming is that lateral stability is poor.
2, four-wheel diaxon vehicle: the static load of wheel load distributes and not only depends on the position of car load barycenter, also relevant with the each rigidity of suspension and amount of compression of spring (road surface concavo-convex) of taking turns.Shortcoming is, while travelling on uneven road surface, the static load of its wheel load distributes and is subject to the concavo-convex impact on road surface larger than three-wheeled vehicle, and vehicle body bears additional torque load.Advantage is that lateral stability is better than three-wheeled vehicle.Due to many one of wheel number, general riding comfort is slightly better than three-wheeled vehicle.
3, three axle four-wheel rhombuses are arranged (axle respectively only has and takes turns) vehicles: the static load of wheel load distributes and not only depends on the position of car load barycenter, also relevant with the each rigidity of suspension and amount of compression of spring (road surface concavo-convex) of taking turns.Shortcoming is, while travelling on uneven road surface, static axle load distribution can change, and may occur concentrating axle load, and vehicle body bears additional bending moment, lateral stability poor (three-wheeled vehicle is similar).Advantage is axis left and right wheel load balance, and vehicle body does not bear additional torque; Due to many one of the number of axle, general riding comfort is slightly better than diaxon vehicle.
4, multiple-axle vehicle: be all generally rectangular arrangement.The static load of wheel load distributes and not only depends on the position of car load barycenter, also with wheelbase and respectively to take turns the rigidity of suspension and the amount of compression of spring (road surface concavo-convex) relevant.Its advantage is: multiaxis supporting, and load is disperseed, and can alleviate deadweight, lowers the center of gravity, and multiple spot input stack filtering improves riding comfort.Its shortcoming is, will produce serious wheel load skewness while conventionally travelling on uneven road surface, not only makes vehicle body bear additional moment of flexure and moment of torsion, but also can reduce the adhesive ability on tire and road surface.
Two, supporting constraint minimizes and is coupled principle:
1, the supporting constraint of four-wheel suspension rectangular arrangement vehicle minimizes: air suspension or the hydro pneumatic suspension of four wheels of compartment, provide four independently " static indeterminacy " vertical constraints to vehicle body, and each wheel load depends on each rigidity and distortion of taking turns spring.In Fig. 1, four great circles represent air suspension or the hydro pneumatic suspension of four wheels, and the heavy line between two springs represents abundant connection.If wherein off-diagonal a pair of (coaxial left and right, or the front and back of homonymy) spring is fully communicated with, make the load of this pair of spring equal or proportional, such incidence relation has just been eliminated a constraint, becomes " static determinacy " system; Two vertical counter-forces that are connected can abbreviation be one and make a concerted effort, and its point of action small circle represents.4 vertical static load constraint reactions originally can abbreviation be three constraint reactions of equivalence, become " intend triangle supporting " (in figure shown in dotted line, the position of leg-of-mutton three vertex representation equivalence supporting-point, lower same), its counter-force is determined by centroid position completely, and has been eliminated the additional torque load to vehicle body.
2, the supporting constraint of six-wheel vehicle minimizes: the vehicle that three axles six are taken turns, generally has six vertical constraints.In Fig. 2, symbol represents with identical above.Be communicated with (noting retaining independently supporting-point of left and right) if realize three pairs of springs, as the abundant connection of the first axle left and right spring, the second axle is fully communicated with the homonymy of the 3rd axle, can realize " intending triangle supporting " system; Conversely, the abundant connection of the 3rd axle left and right spring, the first axle is fully communicated with the homonymy of the second axle, also can realize " intend triangle supporting " system (Fig. 2-1, in 2-2 shown in dotted line).If realize the abundant connection of the first axle, the 3rd axle left and right spring, can realize " intend rhombus supporting " (in Fig. 3 shown in dotted line, the position of four vertex representations equivalence supporting-point of rhombus, lower with).
3, the supporting constraint of multiple-axle vehicle minimizes: the vehicle of the many wheels of multiaxis, generally has the vertical constraint that number is identical with wheel number.If there be N wheel, in order to realize " intending triangle supporting ", in general, need to realize the connection (eliminate N-3 constraint) of N-3 to spring.For this reason, can first all springs be divided into " front left ", " front right ", " rear left ", " rear right " four groups, in this group, each spring is fully communicated with, and forms " intending four-wheel suspension ", again off-diagonal two groups are fully communicated with, become " intending triangle supporting " system.In general, need to realize the connection (eliminate N-4 constraint) of N-4 to spring in order to realize " intending rhombus supporting ".For this reason, can first all springs be divided into " front left ", " front right ", " a middle left side ", " the middle right side ", " rear left ", " rear right " six groups, in this group, each spring is fully communicated with, and forms " intend six and take turns suspension "; Again " front left ", " front right " and " rear left ", " rear right " four groups laterally are fully communicated with to get up respectively, become " intending rhombus supporting " system.The 13-1 of Figure 13 is three axle cars " intending rhombus supports " systems; 13-2 is four axle cars " intending rhombus supports " systems; In Fig. 4, be four kinds of " intending triangle supporting " systems of four axle cars; Fig. 5 is three kinds of " intending rhombus supporting " systems of four axle cars; Fig. 6 is eight kinds of " intending triangle supporting " systems of 5-axle car; Fig. 7 is two kinds of " intending rhombus supporting " systems of 5-axle car; Each summit is the position of bearing reaction.
The grouping scheme that forms " intending four-wheel suspension " and " intend six and take turns suspension " due to multi-wheeler is a lot, therefore forms " intending triangle supporting " and " intending rhombus supporting " system schema also a lot.Here graphic eight schemes that are coupled of taking turns to get on the car, only select some representatives, and other schemes can be by that analogy.
The present invention is the concrete enforcement of the suspension " constrained minimization principle " that proposes of patent applicant.Propose a series of vehicle suspension supporting constraints and minimize embodiment: the abundant connection by hydro-pneumatic spring or air bellow forms " intending triangle supporting " system and " intending rhombus supporting " system; And by flow-controlling gate is set on connecting pipeline, the connection damping of system is controlled, thereby realizing " constrained minimization ", the wheel load uniformization of bringing, eliminates increment load, improves the advantage of ride comfort and ground crossing ability; Meanwhile, overcome by path damping control the Steady-State Steering that the vehicle body bringing because of elimination partially restrained is resisted the shortcoming of inclination and vertical inclineding stability and improved automobile.

Detailed description of the invention
One, draft hitch is all carried in the valve control of four wheeler:
The suspension of each wheel forms by front oil gas elastic element (or air elastic element) 1a, rear oil gas elastic element (or air elastic element) 2a, flow-controlling gate 3 and unimpeded pipeline 4.In four wheel suspensions, there is the wheel suspension spring of a pair of non-diagonal position by flow-controlling gate 3 and a thick mutual UNICOM of unimpeded pipeline 4, thereby four vertical independent restrainings originally, eliminate one, become " statically determinate system " of three independent restrainings.Compared with conventionally there is no the air suspension or hydro pneumatic suspension of four-wheel automobile of height control system, enough large paths of it is a many flow area, flow-controlling gate 3 on this path, the signal transmitting according to the on-off signal of chaufeur and microprocessor 6, size that can control access damping.In the time that automobile travels on uneven road surface, flow-controlling gate area of passage maximum, the rapid balance of pressure between the left and right hydro-pneumatic spring (air bellow) that makes to be communicated with, make left and right wheel load equilibrium, thereby eliminate the torque load to vehicle body, increase road adherence, and improve ride comfort.
Compared with four-wheel automobile hydro pneumatic suspension or air suspension with 3 height control systems, some is similar outwardly, and just the structure of connecting pipeline thickness and control cock is different, but makes system have special performance.Common four-wheel automobile hydro pneumatic suspension or air suspension with height control system, for realizing 3 independent controls, an axle left and right is wherein communicated with, but for ensureing necessary roll angular rigidity, this path needs larger damping, thereby adopt very thin pipeline relatively, " flow regulating valve " that increase left and right circulation damping is often housed.The object of this device is the circulation in order to stop left and right spring.And structure of the present invention be with one enough thick pipeline realize the abundant connection of a pair of non-diagonal angle spring (left and right or front and back), while ensureing that automobile travels on uneven road surface, there is equilibrium of pressure between a pair of oil gas (air) spring, wheel load equilibrium, thereby eliminate the torque load to vehicle body, increase road adherence, and improve ride comfort.In the situation that a pair of left and right spring is fully communicated with, flow-controlling gate must be set in path, in the time that automobile need to increase circulation damping and roll angular rigidity, for example, when automobile turning, microprocessor will send instruction and cut off circulation duct, improve roll angular rigidity, to reduce the inclination of vehicle body.Being communicated with cross-sectional sizes is controlled by flow-controlling gate.And flow-controlling gate is by the microprocessor signals that gathers motion state of automobile, or the control signal being determined by chaufeur controls, thereby can obtain the performance that meets more operatings needs.For example, the size of roll angular rigidity and the ratio of front and back roll angular rigidity can be controlled by flow-controlling gate, thereby the cornering properties (changing deficiency or the oversteer of automobile) of automobile can be controlled.
As application example, four-wheel automobile can adopt four kinds of modes:

2, trailing wheel left and right is fully communicated with " intending triangle supporting " controlled: the thick pipeline connection of rear suspension left and right oil gas (air) spring, therebetween device flow control valve (seeing the 8-2 of Fig. 8, the 10-2 of Figure 10).Its basic controlling logic is as follows: in the time of low speed, flow-controlling gate is opened to maximum, makes the left and right spring balance that fully circulates, performance disappear turns round, even wheel load and improve the effect of ride comfort.In the time of high speed, flow-controlling gate is increased and is turned down gradually with the speed of a motor vehicle, and the roll angular rigidity of rear suspension increases to maximum gradually, to reduce its understeering, and reduces the angle of roll of vehicle body.
3, " intending triangle supporting " of before and after left side, being fully communicated with controlled: the thick pipeline connection of oil gas (air) spring of left side fore suspension and rear suspension, device flow control valve (seeing the 9-1 of Fig. 9, the 11-1 of Figure 11) also can not fill flow-controlling gate in the time that wheelbase is large or the anti-trim ability of suspension is enough therebetween).Its basic controlling logic is as follows: in the time of low speed, flow-controlling gate is opened to maximum, makes a spring before and after the side balance that fully circulates, performance disappear turns round, even wheel load and improve the effect of ride comfort.In the time of high speed, flow-controlling gate is increased and is turned down gradually with the speed of a motor vehicle, and the roll angular rigidity of front suspension increases to maximum gradually, to increase its understeering, and reduces the angle of roll of vehicle body.
4, " intending triangle supporting " of before and after right side, being fully communicated with controlled: the thick pipeline connection of oil gas (air) spring of right side fore suspension and rear suspension, device flow control valve (seeing the 9-2 of Fig. 9, the 11-2 of Figure 11) also can not fill flow-controlling gate in the time that wheelbase is large or the anti-trim ability of suspension is enough therebetween).Its basic controlling logic is as follows: in the time of low speed, flow-controlling gate is opened to maximum, makes a spring before and after the side balance that fully circulates, performance disappear turns round, even wheel load and improve the effect of ride comfort.In the time of high speed, flow-controlling gate is increased and is turned down gradually with the speed of a motor vehicle, and the roll angular rigidity of front suspension increases to maximum gradually, to increase its understeering, and reduces the angle of roll of vehicle body.
Two, three axles six are taken turns and the valve control coupled uniform lotus draft hitch of four axle eight-wheelers:
