Connecting bracket assembly of steering support and front wall panel

Abstract

The invention relates to a connecting bracket assembly of a steering support and a front wall panel for connecting the steering support of an automobile with the front wall panel of the vehicle body. The connecting bracket assembly comprises a steering support transverse pipe, and a steering column mounting bracket and a front wall panel connecting bracket which are welded with the steering support transverse pipe respectively; the front wall panel connecting bracket is a sheet metal part with U-shaped cross section, and the two side faces of the sheet metal part have triangular shapes; the front wall panel connecting bracket is welded with the steering support transverse pipe through a first top end of the triangular side face of the sheet metal part; and one edge, adjacent to the first top end, of the triangular side face is welded with the steering column mounting bracket. The connecting bracket assembly has high structural strength, improves the rigidity and the strength for the connection between the steering support of the automobile and the front wall panel of the vehicle body, and prevents the resonance with the low frequency vibration transferred from an engine compartment; and the connecting bracket assembly is directly connected with the steering column, and the front wall panel and the steering support simultaneously fix the steering column, so that the vibration of the steering column is reduced.

Description

technical field [0001] The invention relates to an automobile part, in particular to a device for connecting the steering support of the automobile with the front wall plate of the vehicle body. Background technique [0002] The connecting bracket assembly between the steering support and the front wall panel is a part used to connect the steering support of the car with the front wall panel of the vehicle body, such as Figure 4 As shown, it is mainly composed of steering column mounting bracket 5, front wall panel connecting bracket 2 and steering support cross tube 3. The steering column mounting bracket and front wall panel connecting bracket are respectively welded to the steering support cross tube, and the front wall panel connecting bracket Bolt through holes 7 that are installed and connected with the front panel of the vehicle body are provided on the top. Among them, the front wall panel connection bracket is a long sheet metal part protruding from the steering su...

AI Technical Summary

Problems solved by technology

[0003] 1. The simple beam structure has limited strength and is extremely easy to be damaged during the collision process, which contributes little to the collision protection of the cab;

[0004] 2. The mode of this structure is low, especially the response to low-frequency vibration is relatively large. The low-frequency vibration transmitted from the engine compartment may cause resonance of the connecting bracket assembly, which is a risk that cannot be completely avoided;

[0005] 3. The steering support vibrates greatly at the part where the steering column is fixed, and the existing connecting bracket assembly between the steering support and the front wall panel cannot directly strengthen the steering column mounting bracket
