Abstract: A clutch unit with a clutch hub mounted non-rotatably on a shaft. The clutch unit includes at least two clutch elements that can be brought into frictional engagement with one another for torque transmission when the clutch unit is actuated by a mechanical actuation device with the help of cable-pull. The mechanical actuation device is attached to and held on the clutch unit.

Abstract: A linear bearing employs spherical roller bodies which are contained in a roller nut body with two drive helixes and two return helixes which form a continuous loop in the nut body. The return helixes are offset from the drive helixes and have a pressure relief cutout to allow for movement of the spherical roller bodies through the return helix region.

Abstract: A wear compensating device, including: at a first axial end, an annularly-shaped base element; an index trigger element connected to the base element; a first annularly-shaped element, at least partially rotatable with respect to the base element, engaged with the index trigger element, and at least partially rotatable with respect to the index trigger element; and at a second axial end, opposite the first axial end, a second annularly-shaped element with a first ramp, the second annularly-shaped element engaged with the first annularly-shaped element and rotatable with respect to the first annularly-shaped element. In response to a specified amount of displacement by a portion of the index trigger element, the first and second annularly-shaped elements are rotatable to change a circumferential position of the first ramp.

Abstract: A clutch including: a first piston displaceable to operate a clutch pack; a second piston; a first fluid chamber partially formed by the pistons, wherein the second piston is displaceable by fluid pressure in the first fluid chamber; and a locking means fixable by the second piston to hold the pack closed. In a preferred embodiment, the locking means includes at least one displaceable ball. In another preferred embodiment, in response to a loss of fluid pressure in the first chamber, the second piston is displaceable to enable displacement of the locking means to open the pack. In a further preferred embodiment, the clutch includes a second chamber, separate from the first chamber and partially formed by the first piston. The first piston is displaceable in response to fluid pressure in the second chamber. The pack remains closed after a loss or reduction of fluid pressure in the second chamber.

Abstract: A water pump disconnect clutch including: a first race having first and second portions with first and second diameters, respectively; a second race having at least one ramp; at least one rolling element disposed radially between the first and second races; and an engagement means for axially displacing the at least one rolling element. In response to an increase in temperature for the pump above a specified level, the engagement means is for axially displacing the at least one rolling element from a first position, in which the first and second races are rotationally independent, to a second position to rotationally lock the first and second races. In response to a decrease in temperature for the pump below the specified level, the engagement means is for axially displacing the at least one rolling element from the second position to the first position.

Abstract: The present invention broadly comprises a gear selector assembly including a tube with at least one engagement feature, arranged to be disposed within a drive shaft for a transmission, the transmission including at least one gear and the drive shaft including at least one gear actuation assembly; and a differential rotation element coupled with the tube and arranged to be coupled with the drive shaft so that the tube is differentially rotatable with respect to the drive shaft. The tube is arranged to differentially rotate such that the engagement feature engages the actuation assembly and the transmission engages a respective gear from the at least one gear. The assembly includes a means for displacing a portion of the differential rotation element such that the tube axially and rotationally displaces with respect to the drive shaft. The portion axially and rotationally engages with an interface element to controllably position the tube.
