Development of High Performance CVT Components

Based on the mass produced CVT components for 350 Nm and ratio coverage of 6, the advances of the following LuK components are described: the pulley sets, the hydraulic control with integrated pump and the chain with guide rail. The potential ranges from 400 Nm with the new fully variable torque sensor and optimized chain to 550 Nm and ratio coverage 7 in power split gearboxes. The further investigations on hydraulics and on powersplit hybrid design will also be shown.
