This clutch cover assembly is the core pressure component of the truck clutch system. It uses high-performance diaphragm spring to provide stable pressing force for friction disc, realizing reliable power transmission and smooth separation during gear shifting. The cast housing features high rigidity and fatigue resistance to handle large torque output under heavy-load conditions. Precision heat treatment ensures consistent elastic performance for long-term operation. Every clutch cover undergoes pressure and fatigue testing before shipment. It fixes common faults such as clutch jitter, difficult disengagement and power loss, serving as an essential replacement part for truck powertrain overhaul.
