A transmission device is provided having a transmission housing, a gear set received in the transmission device having a first gear wheel, which is rotatable about a first gear wheel axis, and a second gear wheel, which engages the first gear wheel and is rotatable abut a second gear wheel axis. In a lateral region of the first gear wheel, there is an oil guidance structure, which is designed as a component produced separately from the transmission housing, and comprises an orifice segment extending radially to the first gear wheel axis, and extends at least in part about the first transmission axis and forms a first lateral surface facing the gear wheel, leaving an intermediate space.

An overrunning clutch clamping body for an overrunning clutch comprises a first contact surface and a second contact surface for contacting respective clamping raceways. The curvature of the contact surfaces deviates from zero in each direction. Each of the contact surfaces is configured symmetrically both to a first plane (E) extending normal to the axis of rotation of the overrunning clutch and to a second plane (E) that is perpendicular to the first plane (E), and the shape of the first contact surface corresponds to the shape of the second contact surface.

Overrunning clutch clamping body

A bushing-type roller overrunning clutch comprising at least an inner or an outer ring that comprises clamping ramps adapted to the needles or rollers, said overrunning clutch further comprising a cage for the needles or rollers, as also pressure springs, said cage comprising cage elements that are made in one piece with the inner or outer ring, and a method of making a bushing-type roller overrunning clutch in which the inner or outer ring together with the clamping ramps and at least one border arranged on one side of the clamping ramps is made by deep-drawing, spring-retaining lugs are cut out of the border, and the spring-retaining lugs are bent radially towards the inner or outer ring and the free-standing tabs of the spring-retaining lugs are bent over into the region of the clamping ramps.

Roller freewheel

A parking lock () of a transmission comprises a parking lock wheel () that is rotationally fixed relative to a shaft () and a locking ring () that is rotationally fixed relative to a housing (), the locking ring () can be displaced axially into a positive locked connection with the parking lock wheel () by an engaging element () and can be released from the locked connection by a hydraulically actuated release element ().

Transmission parking brake

A coupling arrangement () with a first clamping ring () concentric to the axis of rotation (), a second clamping ring () oriented concentrically with the axis of rotation and grooved around its circumference, and with clamping bodies () oriented radially between the clamping rings (); which includes on at least one of the clamping rings projections () that are built into a shape like a ramp (), each of which is placed between two neighboring clamping bodies; and which includes a first retainer () and a second retainer (), with which the clamping rings () and the clamps () are held together.
