ABSTRACT:
The invention relates to a control apparatus for a clutch disc assembly drivingly associated with an engine. Protection from engine stall resulting for inertia loads downstream of the engage clutch disc assembly instantaneously exceeding available engine torque involves sophisticated brakes, intricate sequence controls, and complicated internal clutch control valving. The present apparatus includes a control valve for controllably directing fluid pressure to the clutch disc assembly from a source of fluid pressure. A valve member reciprocally disposed in the control valve is continually urged in a first axial direction. A speed sensor associated with an input member driven by the engine urges the valve member in a direction opposite the first axial direction in response to a decrease in the rotational speed of the input member to a preselected angular velocity slipping the clutch disc assembly. Thus, the engine is protected from stall by limiting the torque load on the engine to a preselected maximum value while avoiding complexity and high cost. Furthermore, the apparatus is accessible for installation and service and is adaptable to existing systems.
