Description

Brief Introduction Of The Product

★ Pull-type structure: featuring a higher lever ratio and a larger lift stroke compared with the push-type structure, it can accommodate higher engine torque.
★ The diaphragm spring is made of 50CrV4/51CrV4 from Baosteel and Wells, well-known domestic steel mills, and adopts the core heat treatment process of Yidong. It boasts high durability, and can withstand 2 million cycles of high-temperature dynamic disengagement durability tests on the bench without failure.
★ The pressure plate is made of HT250 cast iron, adopting a heat dissipation rib structure and a weight-increased design. It has a larger heat capacity than conventional products, which helps reduce the risk of clutch ablation.
★ The clutch cover is made of SPHE from Baosteel, a renowned domestic steel mill. It has a lower deflection coefficient and an increased lever ratio compared with traditional ones, which can improve the working clamping force while achieving a design with lower release force.

Product Feature

• Wave Plate Thermal Stabilization Process: The wave plate is manufactured using a thermal stabilization process, which can effectively improve its thermal attenuation resistance and significantly reduce the deformation attenuation rate during long-term service. Verified by 2 million cycles of fatigue durability tests, the compression attenuation rate of the wave plate can be stably controlled within the range of 5% to 8%. The stable performance improvement can notably optimize the force transmission characteristics of the clutch during the engagement phase, reduce the incidence of jitter failure under vehicle starting conditions, and provide reliable hardware support for the stable operation of the AMT system.
