Abstract

The invention relates to an automobile part, in particular to a torsion beam spring base structure. The torsion beam spring base structure comprises a longitudinal arm flange connected with a torsion beam longitudinal arm and a transverse beam flange connected with a torsion transverse beam. The torsion beam spring base structure further comprises an installation plane and a positioning boss. The installation plane, the longitudinal arm flange and the transverse beam flange are integrally formed. The positioning boss is independently formed. The positioning boss is perpendicularly connected to the installation plane. The torsion beam spring base structure is detached to be two parts in an optimized mode. The two parts are independently stamped to be formed, and then the two parts are connected into a whole structure. Compared with integral forming, the stamping depth is reduced due to the stamping way, cracks are avoided in the forming process, the positioning boss is of a sleeve structure, the structure is simple, installation is convenient, production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to an automobile part, in particular to a torsion beam spring seat structure. Background technique [0002] The torsion beam semi-independent suspension is widely used in small cars and even compact cars due to its simple structure, low manufacturing cost, easy maintenance and less space under the vehicle, which can reduce the height of the chassis and increase the space inside the vehicle. [0003] As the core component of the semi-independent rear suspension system, the torsion beam mainly consists of: torsion bar, torsion beam for bearing the main vertical and lateral moments, longitudinal arms welded on the left and right sides of the torsion beam, for connecting Brackets for the body and braking system, brackets for shock absorbers and springs. The main function of the spring seat in the torsion beam semi-independent suspension is to install the spring and bear the load from the spring. [0004] The existing spring seat str...
