Detailed Description

The wheel bracket is one of the commonly used parts in the rear suspension structural members of the automobile chassis and plays a role in connecting each control arm and supporting the automobile body. Because the rear suspension structure of the chassis is generally more complex than the front suspension structure, the existence of a plurality of control arms and connecting rods occupies a large amount of chassis space, and the existence of the driving half shaft in the rear driving state makes the design space of the wheel bracket very limited.

For example:

In one arrangement for connecting the control arm to the wheel support, as shown in fig. 1a, the bushing 30 'is press fit onto the wheel support 40', and the control arm 10 'is formed as a yoke structure, which are lockingly connected by the bolt member 20'.
