Abstract: A pin for guiding a gear has a substantially cylindrical outer surface section, wherein the outer surface section comprises a substantially cylindrical rolling surface section, which is aligned and formed so as to make possible the guiding of the gear. The outer surface section further has a groove, which is formed so as to accommodate a retaining ring, wherein the groove is disposed with respect to the rolling surface section so as to make possible a guiding, directly or indirectly via the retaining ring, of a rolling-element assembly along the axial direction of the pin. In this way it is possible to provide a guiding of a gear wherein a small tolerance chain is implemented with respect to the axial position.

Abstract: A planetary carrier includes a side plate having a front face and a shaft journal which is arranged on the front face of the side plate. A bearing seating is formed on an outer circumferential surface of the shaft journal on a front-face-proximal end of the shaft journal. The planetary carrier has an annular groove directly adjacent to the bearing seating in coaxial relationship to the shaft journal and undercutting the front face and the outer circumferential surface.

Abstract: A one-way clutch, including: an outer race including a pocket and a strut. The strut includes a body and a retention segment. The body is at least partially locatable in the pocket. The retention segment includes a neck portion and a spring retention portion. The neck portion is directly connected to the body and extends from the body in a first direction. The spring retention portion extends from the neck portion in the first direction and includes first and second segments extending in second and third opposite directions, orthogonal to the first direction, from the neck portion.

Abstract: A power transmission system of a hybrid vehicle may include an input shaft, and an output shaft. A first planetary gear set includes a first rotation element connected to a first motor/generator, a second rotation element operated as an output element, and a third rotation element connected to the input shaft and a second motor/generator. A second planetary gear set includes a fourth rotation element connected to the third rotation element and the second motor/generator, a fifth rotation element connected to the second rotation element through an externally-meshing gear and, and a sixth rotation element connected to a transmission housing. A direct-coupling device connects two rotation elements among the fourth, fifth, and sixth rotation elements of the second planetary gear set, and transfer gears form the externally-meshing gears. Friction elements connect a selected rotation element to a selected transfer gear or a selected rotation element to the transmission housing.

Abstract: An arrangement is provided for supplying oil to a brake arranged for braking an output shaft of a planetary gear. The arrangement includes a rotatable impeller for supplying oil to the brake and the impeller is arranged to be rotated by an input shaft of the planetary gear.

Abstract: An epicycloid planet gear cam that converts rotational movement of a driveshaft into linear movement of an output device is disclosed. An epicycloid planet gear is assembled inside a stationary housing with an internal stationary ring gear. A driveshaft eccentric is connected to a driveshaft. The driveshaft eccentric rotates freely in a mounting hole of the epicycloid planet gear. When the driveshaft rotates, the driveshaft eccentric engages the epicycloid planet gear against the stationary ring gear and causes the epicycloid planet gear to rotate. A cam follower pin attached to an output device is held against a cam track of the epicycloid planet gear. As the epicycloid planet gear rotates, the raised cam track height or the slotted cam track distance from the center of the epicycloid planet gear causes the cam follower pin to move up, down, in, or out thereby moving the output device.

Abstract: A one-way clutch, including an inner race and a wedge component with first and second tapered outer partially circumferential surfaces. The clutch includes first and second outer races including respective tapered inner partially circumferential surfaces. For rotation of the outer races, with respect to the inner race, in a first direction, the outer races are axially aligned and separated by a space in an axial direction, the first and second tapered outer partially circumferential surfaces and the respective tapered inner partially circumferential surfaces are at least partially aligned in radial and axial directions and are free of contact. For rotation of the outer races, with respect to the inner race, in a second direction, opposite the first direction, the first and second tapered outer partially circumferential surfaces contact the respective tapered inner partially circumferential surfaces and the first and second outer races are non-rotatably connected to the inner race.

Abstract: A switchable clutch, including: a first clutch including a first outer race with first and second race plates; a second clutch including a second outer race with third and fourth race plates; an inner hub; and a selector system axially disposed between the first and second clutches, in contact with the first and second outer races, and including a selector plate. For a first operational mode, the selector plate rotates to a first circumferential position to non-rotatably connect the first outer race and the inner hub. For a second operational mode, the selector plate rotates to a second circumferential position to non-rotatably connect the second outer race and the inner hub. For a third operational mode: the selector plate rotates to a third circumferential position and the inner hub is rotatable with respect to the first and second outer races. The first and third plates are axially displaceable.

Abstract: A method of operating a vehicle drive-train during a starting process. The drive-train has a drive mechanism which can couple a continuously-variable power-branched transmission in which a plurality of transmission ratios can be engaged. The transmission ratios can be varied continuously by adjusting a variator, the transmission driving a drive output. A force flow between the drive mechanism and the drive output can be produced by a frictional shifting element by appropriately adjusting the transmission capacity of the shifting element. When a start command is issued, a starting transmission ratio is engaged in the area of the transmission device. During the engagement of the starting transmission ratio the transmission capacity of the frictional shifting element is adjusted to values greater than zero.
