Description

Technical Field

[0001] The utility model relates to the technical field of automobile top glue, in particular to a top glue for automobile shock absorbers. Background Art

[0002] The top mount is used to cushion the impact between the shock absorber and the vehicle body. When driving on uneven roads, each top mount bears more than a quarter of the vehicle body's weight. Compared to ordinary cars, the top mount structure used in trucks requires higher support strength and stability to achieve a long service life of the top mount.

[0003] Chinese utility model CN217603266U proposes a "vehicle top glue". This device mainly solves the problem that the existing top glue used for shock absorbers has poor structural strength during use, which affects its service life. However, the top glue disclosed in this device has a relatively simple internal structure and lacks a heat dissipation structure. As a result, when the top glue absorbs the vibration of the shock absorber and the shock absorber shaft core, the friction and collision between the top glue and the shock absorber shaft will cause the top glue to heat up. If it continues at this temperature, the top glue is prone to qualitative changes, resulting in cracking, which affects its service life. Utility Model Content
