Vehicle fore wheel bulge

Abstract

The invention relates to an automobile front wheel bulge which comprises the rear end of the front wheel bulge. The front wheel bulge is characterized in that: the entrance of the rear end of the front wheel bulge is similar to U shape, a first overlap edge is arranged over the entrance, and the profile of the entrance is provided with a first overlap surface; a mounting bracket of a front damperis box-shaped, the upper part of the mounting bracket is a plane, and the lower part of the mounting bracket is provided with a second overlap edge which is correspondingly connected with the first overlap surface of the rear end of the front wheel bulge; a second overlap surface is positioned under the plane at the upper part of the mounting bracket, and the second overlap surface is correspondingly connected with the first overlap edge of the rear end of the front wheel bulge; and the center of the plane at the upper part of the mounting bracket is provided with a round hole, and the circumference of the round hole is evenly provided with three mounting holes. The automobile front wheel bulge effectively solves the problem of difficult punch forming, has good overlap relationship, and improves the strength, enhances the use reliability and prolongs the service life of the automobile front wheel bulge.

Description

technical field [0001] The invention relates to automobile parts, in particular to an automobile front wheel bulge. Background technique [0002] The front wheel bulge is one of the important load-bearing points of the car body and an important structure that affects the safety and comfort of the car. figure 1 As shown, at present, the front wheel bulge is composed of two parts, the front wheel bulge upper section and the front wheel bulge middle section. Among them, the upper part of the front wheel bulge is approximately a conical funnel-shaped structure. This part is drawn deeply during stamping, and it is prone to defects such as overlapping materials. Therefore, three technological cuts are made in the lower part for material delivery. When the middle section of the bulge is welded, stress concentration is likely to occur at the incision of the process, resulting in defects such as solder joints falling off or cracking in this part during use. However, the middle sect...

AI Technical Summary

Problems solved by technology

Among them, the upper part of the front wheel bulge is approximately a conical funnel-shaped structure. This part is drawn deeply during stamping, and it is prone to defects such as overlapping materials. Therefore, three technological cuts are made in the lower part for material delivery. When the middle section of the bulge is welded, stress concentration is likely to occur at the incision of the process, resulting in defects such as solder joints falling off or cracking during use.

However, the middle section of the front wheel bulge has a large rebound, and the accuracy is difficult to control

Due to the difficulty of stamping, the overlapping sides of the two are short and the fit is not good, resulting in difficulty in welding, which affects its structural performance

[0003] The current bulge structure of the front wheel is unreasonable, resulting in difficulty in drawing during stamping, and the quality of parts cannot be guaranteed

It is difficult to operate during welding, it is impossible to make solder joints, the stamping process and welding process are poor, and the tolerance control is difficult

At the same time, a little force is adopted, the strength is poor, and failures such as cracking and falling off are prone to occur during use, which affects its reliability, service life and safety.
