Differential arrangement in motor vehicle has pressure relief valve arrangement with relief pressure selectively variable based on magnitude of electric current applied to actuator

摘要

The arrangement has a controllable pressure relief valve arrangement (30) for selective control of a frictional coupling arrangement with a valve closure part, a valve seat complementary to the closure part and an electromagnetic actuator. The relief pressure of the pressure relief valve arrangement can be varied selectively based on the magnitude of an electric current applied to the actuator.
