Valeo facings range and application types

Push-type and Pull-type cover assembly technologies:

The cover assembly is designed with the right clamp load to allow the transmission of the engine torque and to limit slippage during the gear shift. The cover assembly consists of the diaphragm, the pressure plate and the cover among which, diaphragm plays the most important role. In Valeo, we carefully follow a precise heat treatment process on each processes of each diaphragm, in order to achieve their high quality.

Modern commercial vehicles are fitted with different types of clutches, depending on the truck manufacturer request. The two principal designs are, push and pull type clutches.

Testing on disc Valeo is using very severe testing criteria, which are exactly the same for both O.E. and IAM parts. Different tests are done: ●● Endurance test ●● Structural reliability test ●● Burst resistance test ●● Hysteresis measurement ●● Truck fitting and running tests
