Description

Technical Field

[0001] The utility model relates to the technical field of clutch cover assembly anti-rotation devices, in particular to a clutch cover assembly anti-rotation device. Background Art

[0002] When the clutch cover assembly is in use, it can squeeze the diaphragm spring. After squeezing, due to the restraint of the two support rings, the edge of the diaphragm spring will bend outward, and the bend will pull the pressure plate by pushing the separation plate and other structures. After being pulled, the pressure plate is no longer pressed against the friction plate and can be completely separated. On the contrary, when the diaphragm spring is not squeezed, the pressure plate and the friction plate are pressed tightly, and the transmission can be engaged at this time. In order to avoid relative rotation and increased wear between the support ring and the diaphragm spring, the pressure plate and the diaphragm spring, the pressure cover and the diaphragm spring, etc., an anti-rotation device is installed, in which the two support rings and the diaphragm spring are usually fixed with rivets. However, the strength of the rivets is limited, and the clamping force is limited. They are prone to loosening after long-term use, resulting in relative rotation between the two support rings and the diaphragm spring. There are certain shortcomings. For this reason, we propose an anti-rotation device for the clutch cover assembly. Utility Model Content
