摘要： A fluid guide assembly for a friction disk clutch comprises an inner disk carrier having a carrier portion, a shoulder portion, and a shaft portion. The carrier portion has a connecting structure for receiving inner disks in a rotationally fixed and axially movable manner; and a fluid guide element which is fixedly connected to the inner disk carrier and which comprises an annular catching portion in which inflowing fluid can be caught, and a plurality of circumferentially distributed tab portions which extend in the axial direction and which each have a radial through-opening. The inner disk carrier has, directed radially outwardly, a plurality of longitudinal grooves which extend axially from the shoulder portion into the carrier portion and which are covered by tab portions of the fluid guide element.

摘要： A differential is provided with: a torque receiving casing; a differential gear set having first and second side gears to differentially distribute torque to the first and second side gears; a clutch interposed between the casing and the first side gear and configured to exert a frictional braking force on the first side gear against the casing to limit a differential motion between the first side gear and the second side gear; an actuator configured to apply a pressing force to the clutch to control the differential motion; and an electronic control unit configured to calculate a demand torque value from the input torque, compare the wheel load with a threshold value to determine a correction value, make a correction in the demand torque value by the correction value to obtain a demand value, and control an electric power supplied to the actuator in response to the demand value.

摘要： A final drive differentially for distributing torque input into a shaft via a differential device to a pair of axles is provided with a ring gear coupled via gearing to the shaft to transmit the torque to the differential device. A housing unitarily includes a main portion supporting the shaft and enclosing the differential device, and a wall portion including a first opening through which one of the axles passes and supporting a first end of the differential device. A cover included a second opening through which the other of the axles passes, and is combined with the housing to support a second end of the differential device, wherein the wall portion, the ring gear, and the shaft are arranged, from the wall portion toward the cover, in an order of the wall portion, the ring gear, and the shaft.

摘要： Differential arrangement, e.g., for a drive axle of a motor vehicle. The differential arrangement comprises a drive wheel; a differential gear having an input part; a shift clutch operatively arranged between the drive wheel and the differential gear, wherein in the closed state of the shift clutch torque is transmitted from the drive wheel to the differential gear and in the open state of the shift clutch a torque transmission is interrupted. A first clutch part of the shift clutch is fixedly connected to the input part or to a differential housing of the differential gear, and a second clutch part of the shift clutch is fixedly connected to the respective other one of the input part and the differential housing.

摘要： A vehicle differential may have multiple gears and include a coil, a drive member movable in response to a magnetic field generated by the coil, with the drive member being movable between a first position and a second position. The drive member has an axis and includes a first body that is magnetically responsive, a second body coupled to the first body, an axis, an axially forward face and a stop surface axially spaced from the forward face, where the stop surface is arranged to limit movement of the drive member away from the first position. A lock member is engaged and driven by the forward face of the drive member to engage a gear of the differential when the drive member is in the second position, and the lock member is adapted to be disengaged from the gear when the drive member is in the first position.
