[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, to achieve the above objectives, this utility model provides the following technical solution: a shock-resistant automobile swing arm, comprising a main body 1 and a bracket 11. A bracket 11 is mounted on one side of the main body 1. A connecting groove 10 is provided on the top of the bracket 11. A connecting seat 8 is installed inside the connecting groove 10. A bushing 9 is installed at one end of the connecting seat 8. A top cover 7 is installed on the outer surface of the bracket 11 above the connecting seat 8, thereby limiting and fixing the connecting seat 8. Locking bolts 17 are installed on both sides of the bracket 11 and the connecting seat 8 through positioning holes 18. A bottom center of the bracket 11 is provided with... The disassembly hole 22 and the connecting groove 10 are provided with a limiting groove 15. The outer surface of the connecting seat 8 is provided with a limiting tooth 16 at the position of the limiting groove 15. The limiting tooth 16 is engaged in the limiting groove 15 to limit and fix the connecting seat 8. The inner sleeve 21 is installed in the middle of the bushing 9 through the damping rubber 20.
