Abstract

The invention relates to a production process of a swing arm bushing, comprising the following steps: glue coating, vulcanization, heat treatment and assembly; heat treatment is performed on the vulcanized bush, so that the shrinkage of the bush is improved, and it is convenient to install The bushing is pressed into the inner hole of the swing arm, which effectively prevents damage to the outer nylon tube of the bushing; at the same time, no traditional riveting tool is needed for pressing, thereby improving the processing efficiency. The invention has a reasonable design and is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to a production process of a swing arm bush. Background technique [0002] With the development of the automobile industry, people have higher and higher demands on automobiles in terms of energy saving, environmental protection, comfort and reliability. Steering wheel shimmy is the main vibration phenomenon in the automobile steering mechanism, which will not only affect the comfort of the automobile, but also have a certain influence on the steering stability. As an elastic connection means to reduce vibration, the main function of rubber bushing is to absorb vibration energy. It is widely used in engine mounts, steering systems and suspension rod hinges. Rubber bushing has become an indispensable and important component in automobiles due to its good vibration isolation performance, elastic characteristics and attenuation characteristics. Therefore, rubber bushes ar...
