Abstract
The invention relates to an adjustable toein torsion beam suspension and a forming method thereof. The suspension comprises a toein control rod and a dragging arm, wherein the toein control rod is connected to a vehicle body by a first liner and is connected with a third liner by a dragging arm; due to a small improvement on the structure of a common torsion beam, the longitudinal flexibility and the lateral steering performance of the suspension are improved considerably; and the improved suspension realizes high performance under a condition of low cost.
Description
Technical field
The present invention relates to that a kind of common relatively torsion girder-like rear suspension can improve that side force turns to and the vertical prenex adjustable torsion beam type suspension of suspension property such as flexibility, be specifically related to adjustable torsion beam suspension of a kind of toe-in and constructive method thereof.
Background technology
Torsion beam type suspension is widely used in the rear suspension of automobile with its advantage such as simple in structure, with low cost, thereby and in medium-to-high grade car in order to realize that the independent suspensions such as many link-types that better road-holding property adopts can will obviously be better than torsion girder-like rear suspension to the accurate control of realizations such as toeing-in angle, camber angle Full Vehicle Dynamics performance.And suspension has played important effect as the important component part of automobile to the road-holding property and the ride comfort of car load, in the design of rear suspension, common independent suspension can be realized the accurate control of wheel is reached road-holding property and traveling comfort preferably, but it is because manufacturing cost is too high, and arrangement space has limited its application on middle-size and small-size manned vehicle greatly.The torsion girder-like rear suspension manufacturing cost is lower, arrangement space obtains maximum interior space than I and be widely used in the middle-size and small-size car rear suspension, but torsion girder-like rear suspension is mainly realized the control of suspension performance by the distortion of beam structure, so limited the raising of the performance of the automobile that adopts this suspension.The every K﹠amp of torsion beam type suspension; Be difficult to make vertical flexibility and side force to turn to two performances to reach balance in the C performance.If want to improve the side force cornering properties, vertical flexibility of suspension is inevitable during the degree of understeer of raising car load reduce significantly, causes travelling comfort very poor; Expect that travelling comfort then must reduce the side force cornering properties preferably, the degree of understeer of car load then is affected.
In sum, have following technical matters in the prior art: existing torsion beam type suspension is difficult to make vertical flexibility and side force to turn to two performances to reach balance, causes travelling comfort difference or car load understeer.
Summary of the invention
The object of the present invention is to provide adjustable torsion beam suspension of a kind of toe-in and constructive method thereof, towing arm front end at common torsion beam suspension installs a lining again additional, only need reasonably be provided with the rigidity of lining and just can realize preferably vertically flexibility and side force turning efficiency.Effectively vertical flexibility and the special performance of side force to suspension realizes accurate control, thereby can effectively improve the dynamic performance of car load, the side force that can increase suspension when vertical flexibility is improved turns to, thereby has improved the road-holding property of car load and the traveling comfort of taking.
Concrete technical scheme is as follows:
The adjustable torsion beam suspension of a kind of toe-in comprises toein control lever and towing arm, and described toein control lever is connected to vehicle body by first lining, and described toein control lever is connected with the towing arm by the 3rd lining.
Further, described toein control lever also is connected by second lining between the arm with towing.
Further, described second lining is the lining that flexibly connects between toein control lever and the towing arm.
Further, vertical setting mutually between described second lining and the 3rd lining.
Further, described vehicle body comprises a crossbeam, and described toein control lever is connected to this crossbeam by first lining.
Further, described toein control lever is two, and described towing arm is two.
The constructive method of the adjustable torsion beam suspension of above-mentioned toe-in, adopt following steps:
(1) installs the 3rd lining additional at towing arm front end;
(2) setting is regulated and finished to the rigidity of this lining.
Further, between towing arm and toein control lever, add second lining.
Further, regulate described second lining and make it to finish flexibly connecting between toein control lever and the towing arm.
Compare with present prior art, the present invention has carried out small improvement to common torsion beam structure, has just significantly improved the vertical flexibility and the side force turning efficiency of suspension, and being suspended under its lower cost after the improvement realized good performance.

The specific embodiment
Describe the present invention with reference to the accompanying drawings below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
The torsion beam suspension that toe-in of the present invention is adjustable comprises, two towing arms, and a crossbeam, two major parts such as toein control lever connect by lining between each parts.Concrete structure as shown in Figure 1.Fig. 2 and Fig. 3 are the dynamical simulation results of this suspension, and Fig. 2 is vertical flexibility curve, and Fig. 3 is the side force steering curve.As can be seen from Figure 2, adopt after this kind suspension frame structure, vertically flexibility is greatly improved and almost can reaches one times of initial vertically flexibility, thereby can obtain good travelling comfort; As can be seen from Figure 3, the side force of suspension turns to the raising that also has clearly, and the degree of understeer of car load is improved like this, and the stability and the stability of enforcement also are improved.To sum up, adopt as can be seen after this design, can obtain the balance between well vertically flexibility and side force turn to, realized the irrealizable function of common torsion beam.
As can be seen from Figure 1, use lining 3 to be connected between toein control lever and the towing arm, interconnect by lining 1 between toein control lever and the vehicle body.Lining 2 between towing arm and the toein control lever has guaranteed flexibly connecting between toein control lever and the towing arm, thereby has prolonged the life-span of towing arm and toein control lever.If be subjected to the restriction of arrangement condition, can only adopt 2 linings to pull interconnecting between arm and toein control lever and the vehicle body.All the other structures of suspension are identical with common torsion beam type suspension.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
