Description

Technical Field

[0001] The utility model belongs to the technical field of clutches, and in particular relates to a sliding clutch. Background Art

[0002] Slipper Clutch, also known as assisted slipper clutch or rebound clutch, is a special type of clutch widely used in high-performance motorcycles. It is designed to improve the vehicle's handling and safety during rapid downshifting.

[0003] In normal operation (acceleration or smooth downshifting), the slipper clutch behaves the same as a conventional clutch; when downshifting quickly, the engine speed suddenly increases, and the special springs in the slipper clutch relax, allowing a certain degree of slip between the clutch plates, thereby reducing the torque transmission of the transmission system and preventing the rear wheel from locking. This design is particularly suitable for racing occasions, but it is also increasingly common on some modern high-performance street motorcycles. It not only improves the safety of the rider, but also enhances the driving experience.

[0004] However, in a traditional sliding clutch, the spring usually passes through the gap of the clutch center sleeve, and the two ends of the spring respectively abut against the top of the pressure plate and the bottom of the lifting plate. When it slides, the spring is prone to offset, resulting in uneven force and affecting the torque transmission effect. Utility Model Content
