Pre-emptive Torque Management™ (PTM)™ 2006-01-0817

Vehicle manufacturers are increasingly demanding an accurate preemptive clutch actuation device to distribute drive torque to secondary axles/wheels. The primary driver behind the need for accuracy is the desire to affect the vehicle handling through active torque distribution. Additionally, the ability to preemptively apply a clutch, independent of differential axle rotation, is also required to assure vehicle stability from launch on various surfaces. Other requirements of such a torque transfer device include fast response time, low hysteresis, low drag torque, and low mass.
