Key components of the clutch pressure plate
2025-07-23
Diaphragm spring: As the core of the clamping mechanism, the diaphragm spring automatically adjusts the clamping force through elastic deformation. Its inner hole circumference surface is distributed with long radial grooves, and the groove roots are made into oblong or rectangular window holes for passing through support rivets (separation fingers).
Separation bearing and sleeve: The separation bearing pushes the inner end of the diaphragm spring, causing the pressure plate to move backward, achieving power disengagement. The separation sleeve plays a guiding and supporting role.
Clamping spring: In a multi-spring clamping device, several spiral cylindrical springs are symmetrically arranged along the circumference of the pressure plate. Some heavy-duty vehicles use a double-spring design (a spring nested inside another spring) or a concentric arrangement to enhance clamping force.
