Abstract

The invention discloses a novel automobile lower suspension arm comprising a lower suspension arm welding assembly formed by welding two stamping parts and a connecting rod, a left rubber bushing assembled on the upper left end of the lower suspension arm welding assembly, a ball pin assembly assembled on the lower end of the lower suspension arm welding assembly in a semi-packaged way, and a right rubber bushing assembled on the right end of the lower suspension arm welding assembly through a connecting rod; wherein the end portion of the right rubber bushing is fixedly connected by a hex nut; and the connecting rod between the right rubber bushing and the hex nut is successively sleeved with a flat washer and a spring washer. In the lower suspension arm of the invention, the lower suspension arm welding assembly is formed by welding the two stamping parts and the connecting rod, which greatly reduces the weight while ensuring the strength, and achieving simple structure and easy assembly.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to a novel automobile lower swing arm. Background technique [0002] The lower swing arm is widely used in the front and rear independent suspensions of cars. It is located between the body and the steering wheel. One end of the swing arm is hinged to the frame, sub-frame or body through a rubber bush, and the other end is connected to the wheel with a ball stud. . The swing arm is the main part of the suspension system guiding device. On the one hand, it transmits force and moment between the wheel and the frame. On the other hand, its layout and size determine the kinematic characteristics of the suspension system. [0003] The swing arm assemblies of the existing lower swing arms are mostly integrally formed solid parts, which are heavy and difficult to assemble. Contents of the invention [0004] In view of this, the present invention provides a new type of automobile lower s...
