Abstract
The invention discloses a double wishbone mechanism for controlling steering of a shaft. The double wishbone mechanism comprises a wheel, a steering knuckle, rubber bushings, an upper wishbone and a lower wishbone, wherein the upper wishbone and the lower wishbone are in a crossed arm type, and are respectively connected with a frame through the rubber bushings; when the double wishbone mechanism is arranged at an initial position, rotating axes of crossed arms of the upper wishbone and the lower wishbone are not on the same straight line, and offset to a certain distance in y and z directions of a coordinate system of a vehicle. With the adoption of the double wishbone mechanism for controlling the steering of the shaft, shaft rotation caused when stresses at the two sides of wheels are not equal in moving process of an automobile is guaranteed, and the handling stability of the automobile is improved.
Description
Technical field
The present invention 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.
Summary of the invention
Technical matters solved by the invention 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 on the suspension of this structure, carry out kingpin caster angle and regulate, to solve the shortcoming in the above-mentioned background technology.
Technical matters solved by the invention 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 present invention, 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 promptly the rotation axis of upper and lower transverse arm changes, and has promptly caused axle steer.
In the present invention, 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, promptly changed the axle steer of automobile.
Beneficial effect: the present invention 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 invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
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 present invention in use, the rubber bush 1 at the yoke place of upper and lower transverse arm 2 can deform, the rotation axis of promptly upper and lower transverse arm 2 changes, and has promptly 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, promptly changed the axle steer of automobile.
More than show and described groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
