Integration type arm swing support device and assembly method thereof

Abstract

The invention relates to an integrated swing-arm pedestal device enabling to make use of an integrated swing-arm pedestal to integrate a rear transverse pull-bar fulcrum pin, an absorber fulcrum pin, a rear swing-arm pedestal reinforced-plate, and a rear transverse pull-bar fulcrum pin bracket to form a whole, and the assembling method thereof. The integrated swing-arm pedestal device of the invention comprises an integrated swing-arm pedestal, wherein, the integrated swing-arm pedestal is provided with a rear transverse pull-bar fulcrum pin mounting hole, an absorber fulcrum pin mounting hole, and a rear transverse pull-bar fulcrum pin bracket mounting portion; the rear transverse pull-bar fulcrum pin bracket is fixed to the integrated swing-arm pedestal by the rear transverse pull-bar fulcrum pin; the integrated swing-arm pedestal, the rear transverse pull-bar fulcrum pin, the absorber fulcrum pin, the rear swing-arm pedestal reinforced-plate, and the rear transverse pull-bar fulcrum pin bracket are integrated by jointing to form a whole. According to the invention, the rear shaft has more centralized parts and the installation position of each part is more reasonable so that the function of each part can be achieved to the maximum extent; the whole device has simple assembly and reasonable design, thus considerably saving the installation space for the rear shaft.

Description

technical field [0001] The invention belongs to the field of vehicles, and in particular relates to an integrated swing arm support that integrates a rear tie rod support pin, a shock absorber support pin, a rear swing arm support reinforcement plate, and a rear tie rod support pin support into a whole An integrated swing arm support device and an assembly method thereof. Background technique [0002] In the prior art, in the semi-independent rear suspension system of an automobile, there is a swing arm to transmit the longitudinal force in the longitudinal direction (the forward direction of the automobile), and a rear tie rod to transmit the lateral force in the transverse direction. Both of them and the rear shock absorber are directly installed on the on the rear axle of the car. Therefore, the rear axle of the automobile must be provided with a shock absorber mounting support, a rear swing arm mounting support and a rear tie rod mounting support pin. The rear axle str...

Problems solved by technology

This structure has the following problems: 1. The number of parts is large and the weight is relatively large; 2. The welding process of each part is relatively complicated due to the welding of each part; Then welded together, so the bearing capacity is limited; 4. Due to the large number of parts, it is inconvenient to arrange on the rear axle
