Abstract
The utility model discloses a two-transverse-arm mechanism controlling steering of a shaft. The mechanism comprises a wheel, a knuckle, rubber bushes, an upper transverse arm and a lower transverse arm. The upper transverse arm and the lower transverse arm are both of a cross arm structure and are respectively connected with a vehicle frame through the rubber bushes. In an initial position, and the rotary axis of a cross arm of the upper transverse arm and the rotary axis of a cross arm of the lower transverse arm are not in the same straight line and deviate certain distances from the y direction and the z direction of a vehicle coordinate system. The two-transverse-arm mechanism can cause shaft rotation when stress on one side of the wheel and stress on the other side of the wheel during operation of the vehicle are not equal, and improves operation stability of the vehicle.
Description
Technical field
The utility model is mainly concerned with the independent suspension field, controls especially for the axle steer in the double cross arm independent suspension.
Background technology
The automobile of present existing double cross arm independent suspension is because automobile is subjected to the effect of side force, longitudinal force (comprising braking force, propulsive effort and surface resistance) and gravity; There is simultaneously the manufacturing of suspension to adjust reasons such as error, tire cornering characteristics again, vehicle is both sides wheel stressing conditions difference in the process of moving, the both sides wheel is rotated around center of moment, thereby axletree produce the i.e. axle rotation that rotatablely moves before and after making in vehicle axis system xy face.When the automobile straight-line travelling, this axle rotates and can change the original travel direction of automobile; When automobile turning travels, may make vehicle be tending towards understeering, also may make vehicle be tending towards negative understeer.At these defectives, need a kind of two transverse arm mechanism that can actuating spindle turns to of design, the safety performance of raising vehicle itself.
The utility model content
The technical matters that the utility model solves is to provide a kind of actuating spindle turns to two transverse arm mechanism, the two transverse arm mechanism that this actuating spindle turns to can be used for the double cross arm independent suspension structure, can carry out kingpin caster angle at the suspension of this structure and regulate, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The two transverse arm mechanism that actuating spindle turns to, comprise Top Crossbeam, lower cross arm, wheel, rubber bush and steering swivel, wherein, Top Crossbeam is the consistent forked arm of structure and shape with lower cross arm, the fork wall of going up in the described forked arm is the vertical transversary of placing with respect to wheel, simultaneously, connect vehicle frames by two rubber bushs respectively at the jag end of forked arm, coupling end then is connected on the car wheel structure by steering swivel.
In the utility model, rubber bush is soft elastic component, and simultaneously, when initial position, the rotation axis of the yoke of upper and lower transverse arm is in-line not, all leaves offset or dish in vehicle axis system y, z direction.
The influence of side force and longitudinal force in the vehicle movement process, both sides wheel stressing conditions difference, then the both sides wheel rotates around center of moment.The rubber bush at upper and lower transverse arm yoke place can deform, and namely the rotation axis of upper and lower transverse arm changes, and has namely caused axle steer.
In the utility model, the position of stressed, the radial rigidity of the size of axle steer and tire, lateral rigidity and suspension system, steering swivel system is relevant.
The rotation axis of upper and lower transverse arm all can move interference in this structure in motion process, and the distortion of the rubber bush at upper and lower transverse arm and the vehicle frame place of connecing can reduce this movement interference, changed the rotation axis of upper and lower transverse arm simultaneously, thereby changed the position of center of moment in the vehicle axis system, namely changed the axle steer of automobile.
Beneficial effect: the utility model utilizes many-body dynamics simulation analysis method of calculating to draw relation between axle steer and offset distance and the rubber bush rigidity, draw axle steer rubber bush rigidity and offset distance hour according to optimum theory again, determine the hard spot coordinate of suspension, can satisfy the requirement of vehicle handling stability.
Description of drawings
Fig. 1 is the scheme drawing of preferred embodiment of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The two transverse arm mechanism that turns to referring to the actuating spindle of Fig. 1, comprise two groups of upper and lower two groups of transverse arms 2, described two groups of transverse arm 2 rear portions are connected on the wheel 4 by steering swivel 3, simultaneously, are connected on the vehicle frame by rubber bush 1 respectively on the end face at the forked position of its front end.
Since the influence of side force and longitudinal force in the vehicle movement process, both sides wheel stressing conditions difference, and then the both sides wheel rotates around center of moment.
The utility model in use, the rubber bush 1 at the yoke place of upper and lower transverse arm 2 can deform, namely the rotation axis of upper and lower transverse arm 2 changes, and has namely caused axle steer.
Simultaneously, the rotation axis of upper and lower transverse arm 2 all can move interference in motion process in this structure, and rubber bush 1 distortion at upper and lower transverse arm 2 and the vehicle frame place of connecing can reduce this movement interference, changed the rotation axis of upper and lower transverse arm simultaneously, thereby changed the position of center of moment in the vehicle axis system, namely changed the axle steer of automobile.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
