Products

Transmission Systems

• The dual dry clutch, a key innovation representing a viable alternative to hydraulic automatic transmissions. With two clutches (one for even gears and one for odd gears), this system allows the driver to change gears 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%;
• 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 a 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. These technologies cover front- and 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, for automatic and continuous variation transmissions.

Electrical Systems and Hybrid and Electric Vehicle Systems

• In the field of micro-hybrid systems, Valeo is the only supplier to offer two stop-start systems, based either on the StARS starter-alternator (Starter Alternator Reversible System) or on a reinforced starter. The second-generation “i-StARS” is externally different due to the integration of control electronics on the electrical machine, reducing the volume and facilitating installation;
• Since 2009, Valeo has been developing a second-generation electric drive-train with enhanced energy performance, aimed at a greater number of potential buyers. Producing an electric drive-train with a limited cost is a major objective for Valeo as it is an essential condition for the mass distribution of second-generation electric cars in an economically viable way, without government aid for purchases. This development is part of a consortium pooling the skills and expertise of several companies in order to encourage the emergence of an electric drive-train industry for vehicles. One of the goals of this joint project is to select the best technological compromises between the different specialties in order to supply the best final product;
• Starters and alternators;
• Electric motor drives;
• Power electronics for hybrid and electric vehicles.

Engine Management Systems and Air Management Systems

• Complete engine control systems for gasoline and VNG (vehicle natural gas) engines;
• Engine control units for direct and indirect injection gasoline applications or those adapted to alternative energies (VNG, Flex Fuel);
• Engine components: ignition coils, injectors, sensors and canister valves;
• EGR (exhaust gas recirculation) and air intake modules.
