Problems solved by technology
In order to improve the driving stability of the car, the assembly position of the rear swing arm of the car often has a certain angle with the axial direction of the vehicle body, so as to release the load laterally and longitudinally. After a long period of use, the installation structure of the rear swing arm is prone to cracking and deformation, which makes it difficult to guarantee the assembly accuracy, and the lateral stiffness is poor, which affects driving safety.

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] Such as figure 1 , figure 2 , Figure 4 and Figure 5 As shown, a rear swing arm of a car according to the present invention includes a rear swing arm body 1, which is a U-shaped sheet metal member, and the lower part of the left side 11 of the rear swing arm body is provided with an outer flange 15, The flange is connected with the rear longitudinal beam 4 of the automobile, and the lower part of the right side 13 of the rear swing arm body is provided with an extension 14, and the extension 14 is connected with the rear section 6 of the side door sill of the automobile. A U-shaped inner reinforcement member 3 is welded between the left side 11 and the right side 13 of the arm body 1, and the rear edge of the bottom surface of the inner reinforcement member 3 is connected to the lower edge of the bottom surface 12 of the rear swing arm body 1. The two side...

The invention relates to a rear oscillating arm of an automobile. The rear oscillating arm of the automobile comprises a rear oscillating arm body, wherein the rear oscillating arm body is a U-shaped metal plate component, a U-shaped internal strengthening component is welded between the two side faces of the rear oscillating arm body, and the two side faces of the internal strengthening component are welded to the left side face and the right side face of the rear oscillating arm body respectively to form a semi-closed box structure. The rear oscillating arm of the automobile further comprises an external strengthening component welded outside the left side face and the bottom face of the rear oscillating arm body, and the external strengthening component and a rear side member and the rear section of a side threshold of the automobile are connected to form a closed cavity structure. Compared with the prior art, the rear oscillating arm of the automobile has the advantages that the internal strengthening component and the external strengthening component are connected to the rear oscillating arm body, so that the strength is enhanced; as the external strengthening component and the rear side member and the rear section of the side threshold form the closed cavity structure, loads can be effectively dispersed and transmitted in various directions of an automobile body, the fatigue strength of the installation connection position of the rear oscillating arm is improved, the problem that the rear oscillating arm is prone to cracking and deforming is solved, and the service life is prolonged.
Description
technical field [0001] The invention relates to auto parts, in particular to an automobile rear swing arm. Background technique [0002] The rear swing arm of the automobile is an important safety part in the chassis system. Its main function is to connect the brake system and the rear longitudinal beam assembly and transmit loads to ensure the wheel alignment parameters. In the design, the rear swing arm is required to have high strength, Good reliability and high assembly precision. In order to improve the driving stability of the car, the assembly position of the rear swing arm of the car often has a certain angle with the axial direction of the vehicle body, so as to release the load laterally and longitudinally. After a long period of use, the installation structure of the rear swing arm is prone to cracking and deformation, which makes it difficult to guarantee the assembly accuracy, and the lateral rigidity is poor, which affects driving safety. And along with peopl...
