Abstract
The utility model provides an automobile rear trailing arm which is provided with only one welding seam, the section of part of a rear trailing arm main body is annular, and the section of the other part of the rear trailing arm main body is approximately square, so that the intensity and the fatigue life of the automobile rear trailing arm are effectively improved, the work efficiency is improved, the cost is reduced, and the automobile rear trailing arm achieves a broad application prospect.
Description
Technical field
The utility model belongs to automotive field, more specifically says to belong to the automotive suspension parts.
Background technology
Of the prior art, the shape of cross section of trailing arm is circular behind the rear overhang rack, and is divided into two bodies in the middle of the trailing arm of back, and the punching press respectively of two bodies is carried out machinework after integrally welded then again.One end and the vehicle body of back trailing arm are rotationally connected, and the other end one side is a spring tray, and cooresponding opposite side is connected with automobile back wheel.Automobile in the process of moving, ground-surface jolts, by trailing wheel be delivered to the back trailing arm on, the back trailing arm is swung up and down, motion so repeatedly, the service life of trailing arm after having a strong impact on, therefore, back of the prior art trailing arm exist intensity and fatigue life relatively poor problem.
Summary of the invention
The problem that will solve of the present utility model provides a kind of rational in infrastructure, trailing arm behind intensity and the fatigue life high automotive suspension.
Trailing arm only has a weld seam behind the automobile; One end cross-sectional plane of back trailing arm is circular, and other end cross-sectional plane is square, and described two varying cross-section shapes are by the bending part transition.
Beneficial effect: back of the present utility model trailing arm has only a weld seam, and the cross section in back trailing arm part main body is circular, another part main body section is square for what be similar to, the intensity and the fatigue life of the back trailing arm that actv. improves, improved work efficiency, reduced cost, be with a wide range of applications.
Description of drawings
Fig. 1 is a trailing arm main structure chart behind the rear overhang rack.
The specific embodiment
As shown in Figure 1, back trailing arm and body contact part, not shown with trailing wheel connecting bridge and spring tray, Fig. 1 only is depicted as the base portion of back trailing arm.In order to raise the efficiency, cost-cutting improves intensity, and back trailing arm adopts the integral plate punching press only to have a weld seam, and therefore, weld seam is few, and good airproof performance all is greatly increased at more former tradition back trailing arm aspect intensity and fatigue life.The cross-sectional plane of one end 1 of back trailing arm is circular, the cross-sectional plane of the other end 2 is square, pass through bending part 3 transition between 1 and 2, owing to only have a weld seam, and corresponding cross sectional shape improves, therefore, be greatly improved intensity and the fatigue life with back trailing arm of this real new structure.
The embodiment in the utility model and the description of accompanying drawing are understood the utility model just to better, to the protection domain of claim without limits.Those skilled in the art make simple adjustment or improvement to accompanying drawing and the foregoing description after reading this specification sheets, still in the protection domain of claim.
Claims (2)
1. trailing arm behind the automobile, it is characterized in that: an end cross-sectional plane of back trailing arm is for circular, and other end cross-sectional plane is square, and described two varying cross-section shapes are by bending part (3) transition.
2. trailing arm behind the automobile according to claim 1 is characterized in that: described back trailing arm only has a weld seam.
