The present invention provides a rotor comprising: a rotor core; a plurality of magnets disposed outside the rotor core; and a molding part disposed outside the plurality of magnets, wherein the rotor core includes a plurality of guide protrusions disposed between the plurality of magnets, and the distance from the center of the rotor core to the outer surface of the molding part passing across the center of one of the guide protrusions is shorter than the distance from the same to the outer surface of the molding part passing across the center of one of the plurality of magnets.

In order to control the disengagement limit position of a movable dog relative to a fixed dog of a motor vehicle transmission, the following steps are implemented: acquiring position values of the movable dog; detecting an abutment position of the movable dog against the fixed dog for a predefined period; and calculating the limit position from the position value of the movable dog in abutment against the fixed dog.

An assembly for actuating a double-acting shift cylinder of a shift assembly of an automatic transmission of a motor vehicle includes a hydraulic fluid reservoir having a motor-driven hydraulic pump and two control valves that are each connected to a pressure supply line of the hydraulic pump and to a return line to the hydraulic fluid reservoir. The shift cylinder has two pressure chambers that are each connected to one of the control valves. The control valves each connect one pressure chamber of the shift cylinder to the pressure supply line of the hydraulic pump or to the return line to the hydraulic fluid reservoir. The actuating assembly includes at least one pressure-limiting valve that connects the pressure supply line to the return line if a hydraulic over-pressure is present. The control valves can be 3/2-directional valves having integrated pressure-limiting valves.

A clutch assembly for a motor vehicle drive train includes a first clutch having a first output element, where the first clutch is a friction-locking clutch. The clutch assembly further includes a second clutch having a second output element, where the second clutch is a form-locking clutch, and where the first clutch and the second clutch have a shared input element. Additionally, the clutch assembly includes a single sliding element associated with the first clutch and the second clutch, the sliding element being movable by a single actuating unit between a first engagement position and a second engagement position axially offset from the first engagement position. The first clutch is engaged when the sliding element is in the first engagement position and the second clutch is engaged when the sliding element is in the second engagement position.

A clutch arrangement arranged between a drive unit and a transmission, with at least one multi-plate clutch having an outer plate carrier and an actuation element. The actuation element, particularly a piston, has openings for receiving the outer plate carrier.

Provided is an automatic transmission which can suppress increase in size. The automatic transmission includes: a transmission mechanism (40) which is disposed in a transmission mechanism storage chamber (4) and has a plurality of transmission elements; a clutch (30) which is disposed in a clutch storage chamber (3), and connects and disconnects power delivery from a driving source to the transmission mechanism (40); and a first control unit (60) which stores first hydraulic control valves (62, 63) that control the transmission mechanism (40), wherein the first control unit (60) is disposed in the clutch storage chamber (3).
