Description

Technical Field

[0001] The utility model relates to the technical field of configuration of a vehicle suspension device, in particular to a vehicle chassis swing arm connecting piece. Background Art

[0002] The swing arm is the connecting mechanism between the frame and the wheel. Its function is to guide and support the suspension. It can effectively improve the stability of the car steering wheel and enable the driver to easily control the direction of the car. The existing utility model with publication number CN211166291 U relates to a car swing arm. By increasing the load impact capacity of the swing arm, the swing arm body is subjected to load impact, and its bottom end is not easy to break, thereby improving the service life of the car chassis swing arm.

[0003] The above-mentioned automobile swing arm has increased the ability to withstand impact loads, making the swing arm less likely to be damaged, but not being easily damaged does not mean that it will not be damaged. After a long period of use, the material strength will decrease, and then the swing arm will break after being subjected to a large impact load. At this time, the swing arm needs to be disassembled and replaced. When disassembling the swing arm, it is necessary to remove the parts around the swing arm that affect the disassembly, and then remove the connecting bolts on the swing arm. Only then can the swing arm be completely removed from the frame and wheel, which makes the replacement of the swing arm more troublesome, and the broken part of the swing arm is mostly in the middle of the swing arm, rather than the connecting hole where the swing arm is connected to the frame and wheel.
