An actuating device with an actuating piston for transmitting an actuating force to a multi-plate device, with a housing section that receives the actuating piston for movement between an open and a closed position. The housing section has a pressure chamber, and the actuating piston delimits the pressure chamber such that, for an increase of a fluid pressure in the pressure chamber, the actuating piston moves from the open into the closed position. A spring resets the actuating piston, and the spring is supported via a first support surface on the actuating piston and a second support surface on the housing section. The first and the second support surface are arranged situated axially opposite one another and overlapping in a radial direction, such that the spring is supported simultaneously in one axial direction on the first support surface and in an axial opposite direction on the second support surface.

A hub-integrated-type constant-velocity joint device in which one hub housing (40) functions as both an outer race of a constant velocity joint and a wheel hub combining a disc (2) of a wheel and a knuckle (3). In this configuration, a boot sealing portion (110) integrally formed at a boot (50) is inserted in a gap (35) between an inner race (32) and an outer race (33) of a bearing (30), thereby functioning as an inner seal closing up the gap between the inner race (32) and the outer race (33).

A generator for comprising a rotor, an inner shaft, an outer shaft, and an actuation means. The inner shaft is at least partially disposed inside the outer shaft. The inner shaft is coupled to the outer shaft by means of a translatable drive connection. The actuation means is configured to actuate the second shaft towards a retracted position. The translatable drive connection is configured to allow a transfer of torque between the first and second shafts, and enables movement of the second shaft, relative to the first shaft, along its axis of rotation from an extended position to a retracted position, such that an input portion of the second shaft can be at least partially retracted in a retraction direction towards the rotor upon activation of the actuation mechanism. A disconnect mechanism disposed on the second shaft can therefore be disconnected upon retraction of the second shaft.

A cooling oil guiding device for a clutch actuatable by an axially movable piston. The piston is radially inward of the clutch, and separates a pressure space and a compensation space. The compensation space is delimited by an axially stationary compensation space cover and a seal cover coupled to the piston. The compensation space cover and the seal cover axially overlap radially outwardly and are axially movable relative to one another via a sealing element. An overflow opening connects the compensation space to an oil channel in the seal cover between the seal cover and the piston, the oil channel opens radially outward. A control edge is provided at a component part axially immovable relative to the piston, by which an oil flow exiting from the oil channel is guided through the clutch when the clutch is closed and is guided past the clutch when the clutch is open.

A cooling oil guiding device for rotating component parts. An annular oil channel extends in radial direction and cooling oil can be supplied from radially inward. The oil channel is partially open radially outwardly. A sealing area is provided in a radially outer area of the oil channel having blocking elements and outlet elements., The blocking elements are arranged radially inwardly of the outlet elements and have at least two passages in radial direction which are distributed along the circumference. Outlet channels aligned with the passages and inlets which are disposed between the outlet channels in circumferential direction are formed by the outlet elements. An annular channel is provided between the blocking elements and the outlet elements to connect the inlets with the outlet channels and passages, respectively.

A gear motor includes a gearing system, an electric motor, and an adapter. The adapter is situated between the electric motor and the gearing system, the adapter has an adapter shaft, the adapter shaft is at least partially inserted into an input shaft of the gearing system, the adapter shaft is connected to the input shaft in a torsionally fixed manner with the aid of a bellows, and a sealing ring is situated between the adapter shaft and the input shaft.

A clutch assembly includes a journal bracket having a center shaft, a drive feature rotatably supported on the center shaft of the journal bracket and configured to accept a torque input to the clutch assembly, a clutch pack that is controllable to selectively transmit torque between an input and an output, a housing attached to the clutch pack that includes a stub shaft, a removable connection engaged between the drive feature and the stub shaft such that torque is transmittable through the removable connection during operation of the clutch assembly, and one or more perpendicular engagement features on the stub shaft configured to accept a tool to engage and disengage the removable connection. At least one of the perpendicular engagement features is exposed to line-of-sight access from a location substantially perpendicular to an axis of rotation of the clutch pack.

A power transmission shaft has a shaft member having, on an outer peripheral surface thereof, a male spline; a cylindrical member having, on an inner peripheral surface thereof, a female spline; and a seal member provided in a pressed state between an outer peripheral seal surface formed on the outer peripheral surface of the shaft member and an inner peripheral seal surface formed on the inner peripheral surface of the cylindrical member. The cylindrical member is spline-engaged with the shaft member by one end side of the shaft member being inserted into the cylindrical member from an other end side of the cylindrical member. Axial direction shock is absorbed by sliding of the splines. The outer peripheral seal surface is positioned at the other end side with respect to the male spline, and the inner peripheral seal surface is positioned at the other side with respect to the female spline.

A sealing boot for sealing a joint of 8 & 8¼ front differentials, where the sealing boot comprises a first sealing boot section having a first cylindrical inside surface. The first sealing boot section is adapted for being tightly fitted to a shoulder section of an end portion of a differential output shaft protruding a housing of the 8 & 8¼ front differential. The shoulder section is disposed between a male spline and the housing. A second sealing boot section has a second cylindrical inside surface. The second sealing boot section is adapted for being tightly fitted to an outside surface section of an end portion of a CV axle shaft having a female spline disposed therein. The female spline being adapted for being engaged with the male spline of the differential output shaft. The sealing boot forms a sealed enclosure between the first cylindrical inside surface and the second cylindrical inside surface.

A clutch assembly includes a journal bracket having a center shaft, a drive feature rotatably supported on the center shaft of the journal bracket and configured to accept a torque input to the clutch assembly, a clutch pack that is controllable to selectively transmit torque between an input and an output, a housing attached to the clutch pack that includes a stub shaft, a removable connection engaged between the drive feature and the stub shaft such that torque is transmittable through the removable connection during operation of the clutch assembly, and one or more perpendicular engagement features on the stub shaft configured to accept a tool to engage and disengage the removable connection. At least one of the perpendicular engagement features is exposed to line-of-sight access from a location substantially perpendicular to an axis of rotation of the clutch pack.
