Products

The technologies developed by Valeo Transmissions include the double dry clutch, one of its key innovations, which is a genuine alternative to hydraulic automatic transmission. With two clutches (one for even gears and one for odd gears), this system allows the driver to change gear with no interruption to torque and no jolting, just like an automatic transmission. Without a hydraulic circuit, it also improves efficiency, cutting consumption by 4-6%.

Other products produced by this Product Family include:

• clutches with and without self-adjusting technology;
• clutch discs with a new generation of multi-louver dampers offering effective protection from vibrations;
• environmentally friendly clutch facings with no heavy metals, manufactured using an water-based process;
• release bearings with built-in automatic self-centering;
• hydraulic clutch actuators;
• flexible flywheels that provide effective reduction of the axial vibrations generated by the engine;
• dual mass flywheels, with rigid or flexible primary flywheel and the option to add an internal damper to improve filtration efficiency in front- or rear-wheel drive vehicles with either manual gearboxes, dual clutches or hybrids;
• torque converters, including a lock-up function, wide clearance damper and an optimized hydraulic circuit.
