Description

Technical Field

[0001] The utility model relates to a clutch of a three-wheeled motorcycle engine, in particular to a dry clutch used for a three-wheeled motorcycle. Background Art

[0002] A dry clutch is one that uses air to cool the clutch. During use, the clutch is required to be able to engage and disengage with the power easily and freely, and to work in a semi-clutch state for a short period of time, and the clutch should not overheat. Because there is no resistance from the engine oil, the dry clutch generally has a faster bite response and a stronger bite force. Also, because there is no engine oil cooling, the dry clutch generally uses an exposed method to dissipate heat.
