Abstract

The invention discloses an automotive rear suspension with a compliance steering function. The automotive rear suspension comprises a cross beam, a left longitudinal arm and a right longitudinal arm, wherein the left longitudinal arm and the right longitudinal arm are symmetrically arranged at the two ends of the cross beam; a left bushing and a right bushing are slantwise and symmetrically arranged on the end parts of the left longitudinal arm and the right longitudinal arm at the front end of a vehicle body; a left rear spring seat and a right rear spring seat are arranged on the left longitudinal arm and the right longitudinal arm on the rear part of the cross beam; the cross section of the cross beam has a V-shaped structure with an forward opening; and a transverse stabilizing rod is arranged between the left longitudinal arm and the right longitudinal arm above the cross beam. The automotive rear suspension has the advantages of simple structure and low cost, when the driving speed exceeds a certain limit value, a rear suspension system can ensure that rear wheels deflect to a certain extent opposite to a frame and keep the deflection in the same direction as that of the front wheels by using the flexible deforming of a rear suspension during steering of an automobile, so that the compliance steering function of the rear suspension is realized, the stability and the operability of high-speed driving of the automobile are improved, and the rear suspension is very suitable for the rear suspension system of multi-purpose vehicle (MPV) automobiles and saloons.

Description

Rear overhang rack with follow-up steering function
Technical field
The present invention relates to the rear overhang frame system, especially relate 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
The object of the present invention is to provide 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.
For achieving the above object, the present invention can take following technical proposals:
Rear overhang rack with follow-up steering function of the present invention, 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.
The invention has the advantages that 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 invention.
The specific embodiment
As shown in the figure, the rear overhang rack with follow-up steering function of the present invention, 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.
