DAMPER SYSTEM FOR CONTROLLED ENGAGEMENT OF A TORQUE TRANSFER MECHANISM

Apparatus and method for selectively controlling the response characteristics of a torque transfer mechanism such as an automobile clutch. A damper has an outer housing and an extendable piston rod connected between a linear bearing cartridge and a clutch arm. A retention pin is selectively extended to hold the bearing cartridge while the rod is extended as the clutch arm is moved from an engaged position to a disengaged position. Upon release of the clutch arm, the pin is retracted and the damper applies a damping force upon the clutch arm as the rod is retracted into the housing. The system is particularly suited for engagement of first gear in a drag racing car to provide optimum initial acceleration of the car.
