ABSTRACT:
A hydraulic torque-coupling assembly that includes a pressure relief valve with an annular solenoid actuator assembly that moves axially to engage an annular valve actuator ring to selectively close a pressure relief valve disposed on the outer face of a torque-coupling case. The annular solenoid assembly does not include a conventional armature so that the coil portion of the solenoid actuator assembly moves into and out of engagement with the annular valve actuator ring. The valve actuator ring rotates with the torque-coupling case, however, the solenoid assembly does not rotate. The valve actuator ring and solenoid assembly are mounted outside the differential case. A variable amount of electrical current is applied to the solenoid assembly so that the release pressure of the pressure relief valve assembly is selectively based on the magnitude of an electric current supplied to the solenoid assembly.
