Shock absorber seat, shock absorber assembly and vehicle

Abstract

The invention relates to a vehicle shock absorber and particularly discloses a shock absorber seat, a shock absorber assembly and a vehicle. The shock absorber seat comprises a body (1), wherein the body (1) is provided with a through hole (2) into which a shock absorber extends and a plurality of mounting holes (3) for fixing the shock absorber; the first molded surface (4) located on the outer side of the mounting hole (3) in the outer side of the front portion of the body (1) is sunken in the body (1), and the second molded surface (5) located on the front portion of the mounting hole (3) in the outer side of the front portion of the body (1) is sunken in the body (1). Compared with a shock absorber seat with a planar molded surface in the prior art, the shock absorber seat has the advantages that molded surface optimization is carried out on the strength weak area of the shock absorber seat, the molded surface is set to be concave, although the concave molded surface is thinned, the stress edges of the whole shock absorber seat are increased, the stress at the stress edges is dispersed, the whole strength of the shock absorber seat is improved, and the cracking risk is reduced.

Description

Technical field [0001] The invention relates to a shock absorber for a vehicle, in particular to a shock absorber seat. In addition, the present invention also relates to a shock absorber assembly and a vehicle. Background technique [0002] Automobile shock absorbers are usually set between the chassis and the body of the car. When the car is driving on uneven roads, the up and down jumps of the wheels cause the chassis and the body to vibrate and bump up and down. The damping effect of the shock absorber can buffer and reduce the body. The load received to reduce the up and down bumps of the body. As one of the key components of load transmission, the shock absorber mounting support not only requires sufficient rigidity and strength, but also transmits the load to all parts of the car body to the greatest extent to ensure the reliability and durability of the car body . [0003] The existing car front shock absorber mounting support generally includes a mounting support body. ...

AI Technical Summary

Problems solved by technology

However, the strength increase of the shock absorber mounting support of this solution is limited, and it cannot meet the increasingly lightweight requirements of the current automotive field.

[0005] In addition, in the prior art, there is also a method of increasing the thickness of the material to increase the strength, such as the shock absorber seat of the reference benchmark car (for the structure, see image 3 Shown) material thickness increased from 2.5mm to 2.8mm, CAE analysis of the maximum plastic strain and residual displacement, the results see Figure 4 As shown, the situation of insufficient strength has not been greatly improved, and it cannot meet the increasingly lightweight requirements of the current automotive field.
