Description

Technical Field

[0001] The utility model belongs to the technical field of buffer discs, and particularly relates to a buffer disc and an improved guide block thereof. Background Art

[0002] A shock-absorbing disc, also known as a buffer disc, especially a shock-absorbing disc in a gearbox, is a device used to buffer and reduce vibrations and impacts generated during power transmission. It protects the gearbox and other related components from damage by absorbing and dispersing energy. The shock-absorbing disc can effectively absorb and disperse the impact force transmitted from the engine to the gearbox, reduce the jerks during gear shifting, and make the gear shifting process smoother.

[0003] During the use of the existing shock-absorbing disc, the guide block inside the shock-absorbing disc is made of plastic. After long-term use, the guide block is prone to fragmentation. The guide block made of plastic not only has a short service life but also has relatively general stability during use. As a result, the staff needs to replace the shock-absorbing disc, resulting in a relatively general use effect of the device. Therefore, the staff needs to improve the device.
