发明名称 LIMITED SLIP DIFFERENTIAL
摘要 A limited slip differential assembly includes a planetary gear assembly, a differential case, a differential gear assembly and a hydraulic clutch assembly. The differential case is coupled for rotation with a portion of the planetary gear assembly. The differential gear assembly is arranged within the differential case and includes a first side gear and a second side gear for coupling with first and second drive wheels of a vehicle, respectively. The hydraulic clutch assembly includes a clutch pack and a clutch actuator. Pressurized hydraulic fluid from a transmission pump is selectively provided to the clutch pack to actuate the clutch pack between an open configuration, in which the side gears rotate independently, and a fully closed configuration, in which the side gears rotate together such that the first and second drive wheels rotate at a same speed.

主权项 1. A limited slip differential assembly for a vehicle, comprising: a planetary gear assembly including a sun gear, a plurality of planet gears and a ring gear, the sun gear being rotatably coupled to a transmission and configured to transmit rotational force to the plurality of planet gears; a differential case coupled for rotation with the plurality of planet gears; a differential gear assembly arranged within the differential case and including a first side gear and a second side gear coupled to first and second drive wheels of the vehicle, respectively; and a hydraulic clutch assembly coupling the planetary gear assembly with the differential gear assembly, the hydraulic clutch assembly including a clutch pack and a clutch actuator, the clutch actuator being in fluid communication with a transmission pump of the vehicle such that pressurized hydraulic fluid from the transmission pump is provided to the clutch pack to selectively actuate the clutch pack between an open configuration and a fully closed configuration, wherein the clutch pack includes a plurality of annular plates interleaved with a plurality of annular friction disks, the plurality of annular plates being coupled for rotation with one of the differential case and the differential gear assembly and the plurality of annular friction disks being coupled for rotation with the other one of the differential case and the differential gear assembly, wherein (i) the open configuration corresponds to the plurality of annular plates and the plurality of annular friction disks being configured to rotate independently in a substantially non-contacting relationship, and (ii) the fully closed configuration corresponds to the plurality of annular plates and the plurality of annular friction disks being configured to rotate together in a contacting relationship, and wherein the first and second side gears: (i) rotate independently in the open configuration such that the first and second drive wheels can rotate at different speeds, and (ii) rotate together in the fully closed configuration such that the first and second drive wheels rotate at a same speed.
