Abstract
The utility model discloses an automobile rear suspension with a compliance steering function, which comprises a cross beam, a left trailing arm and a right trailing arm, wherein the left trailing arm and a right trailing arm are symmetrically arranged at the two ends of the cross beam; a left bushing and a right bushing are obliquely and symmetrically arranged at the end parts of the left and the right trailing arms at the front end of an automobile body; and a left rear spring seat and a right rear spring seat are arranged at the left and the right trailing arms at the rear end of the cross beam. The cross section of the cross beam is a V-shaped structure with an opening facing forward. A stabilizer bar is arranged between the left and the right trailing arms above the cross beam. The automobile rear suspension has the advantages that the structure is simple, the cost is low, when the driving speed exceeds a certain limit value, a rear suspension system can enable a rear wheel deflects to a certain extent relative to an automobile frame and keep to deflect in the same direction with a front wheel by utilizing the flexible deformation of the rear suspension caused during the steering of the automobile, thereby achieving the compliance steering function of the rear suspension and improving the stability and the controllability of the automobile driving at a high speed, and the automobile rear suspension is very suitable for being used in a rear suspension system on MPVs (multi-purpose vehicles) and cars.
Description
Technical field
The utility model relates to the rear overhang frame system, especially relates to a kind of rear overhang rack with follow-up steering function.
Background technology
Multipurpose automobile (MPV automobile) becomes people's new lover gradually with its practicality, traveling comfort and safety at present.The rear-suspension system of this class automobile adopts leaf spring structure and multi-link structure mostly, because leaf spring structural damping poor performance can not satisfy the traveling comfort requirement of MPV manned vehicle, and the multi-link lever suspension fork complex structure, the cost height is unfavorable for the reduction of integral vehicle cost, and comparing with similar car does not have the market competitiveness.
Summary of the invention
It is a kind of simple in structure, with low cost and can improve the rear overhang rack with follow-up steering function of whole vehicle stability that the purpose of this utility model is to provide.
For achieving the above object, the utility model can be taked following technical proposals:
Rear overhang rack with follow-up steering function described in the utility model, it comprises crossbeam, is symmetricly set on the left and right trailing arm at described crossbeam two ends; The sloped-end of the left and right trailing arm of described car body front end is symmetrically arranged with left and right lining; The left and right trailing arm at described crossbeam rear portion is provided with left and right rear spring seat.
The transversal surface of described crossbeam is opening " V " shape structure forward.
Between the left and right trailing arm above the described crossbeam, be provided with Panhard rod.
Advantage of the present utility model is simple in structure, with low cost, when road speed surpasses a threshold value, the plastic deformation of rear suspension when this rear-suspension system can utilize motor turning, make the relative vehicle frame of trailing wheel produce certain deflection and trailing wheel only keeps and front-wheel deflection in the same way, thereby realized the follow-up steering function of rear suspension, improve the stability of galloping and handling, be suitable for very much the rear-suspension system of MPV automobile and car.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the rear overhang rack with follow-up steering function described in the utility model, it comprises crossbeam 1, is symmetricly set on the left and right trailing arm 2,3 at described crossbeam 1 two ends; The sloped-end of the left and right trailing arm 2,3 of described car body front end is symmetrically arranged with left and right lining 4,5; The left and right trailing arm 2,3 at described crossbeam 1 rear portion is provided with left and right rear spring seat 6,7.The transversal surface of described crossbeam 1 is opening " V " shape structure forward; Between the left and right trailing arm above the described crossbeam 12,3, be provided with Panhard rod.
Crossbeam 1 makes it have stronger bearing capacity for the opening v-shaped structure forward with the steel plate drawing; Left and right trailing arm 2,3 can be selected the vertical masonry joint electric welded steel pipe of welding for use, and is welding between left and right trailing arm 2,3 and the crossbeam 1, and the Panhard rod two ends also are welded on respectively on the left and right trailing arm 2,3, play the anti-roll effect when car body turns to.
The left and right lining 4,5 that connects car body tilts to be symmetricly set on the end of left and right trailing arm 2,3, the axis that is left and right lining 4,5 is " eight " font layout, make and turn to the left and right lining 4,5 in back that plastic deformation takes place, left and right trailing wheel 8,9 relative car bodies produce certain deflection and trailing wheel only keeps and front-wheel deflection in the same way, thereby have realized trailing wheel 8,9 follow-up steering functions.As can be seen from Figure 1, when the automobile turnon left, car load barycenter A point (direction of arrow) to the left travels, ground offers left and right trailing wheel 8,9 side force of (arrow) direction left, because the distortion of the left and right lining 4,5 of rear suspension, make rear suspension form the yaw center of turn at the B point, the yaw center of turn that the side force at left and right trailing wheel 8,9 places is ordered relative to B has formed the trend of rotating (as shown by arrows) of direction left, thereby make two trailing wheels certain angle that turns left respectively, consistent with the motor turning direction, thus realized the follow-up steering function.This rear suspension with follow-up steering function has improved the stability of running at high speed by bike and handling, and simple in structure, with low cost, is highly suitable for the rear suspension of MPV automobile and car.
