A half-shaft assembly includes a first constant velocity (CV) joint, a second CV joint and an axial movement joint connected between the first CV joint and the second CV joint. The axial movement joint includes a first shaft coupled to the first CV joint and a second shaft coupled to the second CV joint, wherein mechanical input received on the first shaft is communicated to the second shaft, and wherein the second shaft slides axially within the first shaft. The axial movement joint further includes an axial boot cover coupled on a first end to the first shaft and on a second end to the second shaft that accommodates axial movement of the first shaft relative to the second shaft. The first constant velocity (CV) joint is coupled to provide torsional input received at an input to the first shaft, the first CV joint having a first CV boot cover. The second CV joint coupled to provide torsional output received from the second shaft to an output, the second CV joint having a second CV boot cover.

A flexible coupling assembly for a power transmission system includes a first circular disk defining a u-shaped radial cross-section including a first leg and a second leg connected at an inner diameter thereof circumscribing an axial bore of the flexible coupling and disconnected at an outer diameter of the first circular disk configured to connect to a first rotating member interface and a second circular disk defining a u-shaped radial cross-section including a first leg and a second leg connected at an inner diameter thereof circumscribing the axial bore of the flexible coupling and disconnected at an outer diameter of the first circular disk configured to connect to a first rotating member interface.

The present invention relates to a disk clutch (2) comprising a first disk carrier (18), a second disk carrier (24), and a disk set (34) assigned to the first and second disk carriers (18, 24), wherein the first and second disk carriers (18, 24) may be brought in a friction-locking way into rotary driving connection with one another via the disk set (34), and the first and the second disk carrier (18, 24) may additionally be brought in a positive-locking way into rotary driving connection with one another.

A power take off includes a housing, an input mechanism that is supported in the housing and is adapted to be rotatably driven by a source of rotational energy, and an output mechanism that is supported in the housing and is rotatably driven by the input mechanism, the output mechanism being adapted to rotatably drive a rotatably driven accessory. The power take off further includes a two piece damping assembly that minimizes the transmission of torque transients from the input mechanism to the output mechanism. The two piece damping assembly may be an input cluster gear assembly that includes a first gear portion and a second gear portion that are supported for rotational movement relative to one another. The two piece damping assembly may also be part of a clutch assembly for selectively the output mechanism to be rotatably driven by the input mechanism.

A wedge plate for a wedge plate clutch, including: a radially inner surface with a plurality of ramps, each ramp sloping radially inwardly in a first circumferential direction; a radially outer surface; a first circumferential end; a second circumferential end; a gap separating the first circumferential end from the second circumferential end in the first circumferential direction; a first slot open to the radially inner surface and extending radially outwardly; a second slot open to the radially outer surface and extending radially inwardly; and a portion circumferentially located between the first slot and the second slot. a first line passes through the axis of rotation and the portion. A second line passes through the radially inner surface, the portion and the radially outer surface without passing through the first slot or the second slot. An acute angle is formed between the first line and the second line.
