ELECTRO-HYDRAULIC CONTROL SYSTEM FOR A HYDRAULIC TORQUE VECTORING DIFFERENTIAL

摘要

A differential system for a front wheel drive vehicle. The differential system including a differential carrier (24), an actuator housing (44), an intermediate shaft (32), a dutch pack (42), and a piston (40). The differential carrier (24) houses a differential assembly (18) configured to drive a right and left axle shaft. The actuator housing (44) is configured to rotate in conjunction with the differential carrier (24). The intermediate shaft (32) extends through the actuator housing (44). The dutch pack (42) has a first set of clutch plates (48) that engage the actuator housing (44) and a second set of clutch plates (48) that engage the intermediate shaft (32). The piston (40) compresses the first and second set of clutch plates (46, 48) thereby frictionally coupling the differential carrier (24) to the intermediate shaft (32) and the locking or modulating the differential.
