Description
Technical Field
[0001] This utility model relates to the field of automotive suspension technology, specifically to a double wishbone bracket for automotive suspension. Background Technology
[0002] The suspension is one of the most important assemblies in a car. It elastically connects the body and wheels together. The main function of the suspension is to transmit all forces and torques acting between the wheels and the body, such as support force, braking force and driving force, and to mitigate the impact load transmitted to the body from uneven road surfaces, dampen the resulting vibrations, ensure the comfort of passengers, and reduce the dynamic load on cargo and the vehicle itself. The suspension requires a support frame for support.
[0003] Most double wishbone suspension brackets on the market are currently manufactured as a single piece. After prolonged wear, the ball joints on these brackets require replacement of the entire bracket, which is costly. Existing solutions involve making one end of the ball joint retaining block open and sealing it with a pressure block and bolts, thus allowing for ball joint replacement. However, the ball joint retaining block also wears down along with the ball joint. Even after replacing only the ball joint, the severe wear on the inner wall of the retaining block still affects its usability. Therefore, those skilled in the art have provided a double wishbone suspension bracket for automotive suspensions to address the problems mentioned in the background section. Utility Model Content
