Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle clutches, in particular to an anti-impact structure of a friction plate of a motorcycle clutch. Background Art

[0002] As a convenient and efficient means of transportation, motorcycles have seen rapid market demand and technological development in recent years. As a key component in the motorcycle transmission system, the performance of the clutch directly affects the driving experience and safety of the motorcycle. The motorcycle clutch friction plate is an important part of the clutch system, and its main function is to achieve power transmission and separation through friction. However, in actual use, the motorcycle clutch friction plate is often faced with high-frequency starting, acceleration, deceleration and other operations, which will generate large instantaneous impact force and high temperature, bringing severe tests to the durability and stability of the friction plate.

[0003] Existing motorcycle clutch friction plates mainly use a single material or a simple composite material structure, such as asbestos-based, paper-based or metal-based friction plates. Although these friction plates can meet the needs under ordinary driving conditions to a certain extent, their impact resistance and high temperature resistance are often insufficient in high-intensity use scenarios. Traditional friction plates are prone to rapid wear under high-frequency friction and high temperature conditions, resulting in a shortened service life. Due to the lack of an effective buffer structure, the friction plate is prone to material fracture or delamination when subjected to instantaneous impact force. In view of this, we propose an impact-resistant structure for motorcycle clutch friction plates. Utility Model Content
