Front support of passenger car chassis control arm

Abstract

The invention discloses a front support of a passenger car chassis control arm, which is fixed on an auxiliary frame of a passenger car chassis when being used. The front support is mainly characterized in that a right-angle opening is processed in the upper side in the front support of the control arm, the flanging of the front support of the control arm is beveled to form a bevel edge of 45 degrees, the outer side edge of the front support of the control arm stretches upwards to the top the height of which is one third of the height from the top to the bottom of the front support, a triangular rib plate is processed in the middle part of the bottom edge of the front support of the control arm, and the inner side of the bottom edge of the front support of the control arm is processed to be in the shape of a stair-step. According to the structure of the front support, the stiffness of the front support is improved, and stress concentration is eliminated, so that the front support is more suitable for working in a complicated vibration environment and can be applied to the manufacturing field of passenger-car chassis installation kits.

Description

technical field [0001] The invention relates to the field of manufacturing car chassis spare parts, in particular to a control arm front bracket capable of improving the overall static stiffness of a car chassis sub-frame. Background technique [0002] Traditional car chassis control arm front bracket such as figure 1 shown. Because the traditional control arm front bracket works in a complex vibration environment for a long time, it is often easy to cause figure 1 Cracks appear in parts 1 and 5, which leads to the decrease of its own stiffness and the overall static stiffness of the subframe. Once a crack occurs, it is very difficult to repair the crack in the small chassis space. Therefore, in the past, it is generally used to replace the front bracket of the control arm, which is cumbersome and inefficient. Direct replacement of the front bracket of the control arm will increase the use cost of the car. Contents of the invention [0003] The purpose of the present ...

Because the traditional control arm front bracket works in a complex vibration environment for a long time, it is often easy to cause figure 1 Cracks appear in parts 1 and 5, which leads to the decrease of its own stiffness and the overall static stiffness of the sub-frame

Once a crack occurs, it is very difficult to repair the crack in the small chassis space

Therefore, in the past, it was generally used to replace the front bracket of the control arm. The operation is more troublesome and inefficient. Directly replacing the front bracket of the control arm will increase the use cost of the car.
