In at least some implementations, a clip for restricting the axial movement of at least one of an inner shaft or an outer shaft relative to the other shaft includes a first free end, a second free end, an opening defining an open end of the clip between the first free end and the second free end, a closed end opposite the open end, at least three control zones, and a plurality of intermediate zones. Each intermediate zone has a varying width and each is disposed adjacent to at least one of the at least three control zones.

Retainer for inner and outer shafts

One implementation of a vehicle power transfer unit (PTU) housing, such as that for an automobile, has an oil feed passage extending through one of its walls and at its interior. The oil feed passage delivers oil to gears, bearings, and/or other components equipped inside of the PTU housing and suspended above an oil bath in the PTU housing. Oil of the oil bath is thrown about by rotating gears and makes its way through the oil feed passage and to the gears, bearings, and/or other components. With the oil feed passage, the PTU housing does not rely solely on oil sloshing and splashing and being slung around inside of the PTU housing as the technique for getting oil to the gears, bearings, and/or other components.

In at least some implementations, a disconnect assembly for a power transfer unit includes a cam and a cam follower. The cam is driven for rotation and has a cam surface that is inclined relative to an axis of rotation and a void spaced from the cam surface. The cam follower has a cam engagement surface and is arranged to be engaged by the cam surface so that the cam follower is displaced axially during at least a portion of the rotation of the cam. One or both of the cam and the cam follower includes an interface surface provided at an angle to the axis of rotation to control axial movement of the cam follower during at least a portion of the rotation of the cam when the cam surface is not engaged with the cam engagement surface.

Shift collar assembly for a power transfer unit

A vehicle power transfer unit (PTU) disconnect assembly can include a first shaft, a second shaft, and a collar assembly. The first shaft has a first split-spline at its exterior surface. The second shaft is telescoped over the first shaft and has a set of splines at its exterior surface. A helical gear is carried by the second shaft. The collar assembly is situated around both of the first and second shafts. The collar assembly has a second split-spline at its interior surface.

An exemplary constant velocity joint includes a first member and a second member rotatably engaging the first member. A clutch pack is disposed between and engages the first and second members. A fastener is used to attach the first member to the second member. The fastener is fixedly connected to the second member and rotatably engages the first member. The fastener exerts a biasing force for urging the first and second members into engagement with the clutch pack.

Constant velocity joint with torque overload protection

An automotive shaft assembly is provided including a first barshaft having a first connection end and a second barshaft having a second connection end. A connection tube rotationally engages the first connection to the second connection end and includes a shear diameter configured to experience shear failure in the presence of an overload torque such that the first connection end is rotationally disengaged the said second connection end.

Sideshaft with interconnecting fuse

A vehicle joint assembly is provided comprising an outer race having an outer surface and an inner surface. A pair of opposed slot tracks are formed in the inner cup surface and each comprise a track top wall and two track sidewalls. A barshaft is in communication with a bipod element comprised of a body portion and two opposed peg portions. Each of the two opposed peg portions comprises two opposed curved engagement surfaces engaging one of the track sidewalls. The bipod element is positioned within the outer race such that each of the opposed peg portions resides in one of the opposed slot tracks. The bipod element is capable of being positioned in a variety of angles within the slot tracks and is capable of plunging within the slot tracks.
