Abstract: A vehicle comprising at least one electric drive machine and a coupling mechanism switchable between a coupling position, where the electric drive machine is coupled to a drive wheel so as to transmit torque, and a decoupling position where the electric drive machine is decoupled from the wheel. A parking lock device has a parking lock element movable between a parking lock position, where the parking lock element blocks a rotation of the wheel, and an unlocking position in which the parking lock element releases rotation of the wheel. An actuation device comprises an actuator to actuate a clutch of the coupling mechanism, said clutch having a switching element pretensioned by spring force on a housing of the coupling mechanism and used to switch between the coupling position and the decoupling position, and which moves the parking lock element between the parking lock position and the unlocking position.

Abstract: A supply device for an apparatus includes: a first flow path through which a fluid can flow; a first consumer which is arranged in the first flow path and can be supplied with the fluid via the first flow path; a pump which is arranged in the first flow path and by which the fluid can be pumped out of a reservoir through the first flow path; a throttle which is arranged in the first flow path upstream of the first consumer and downstream of the pump; a second flow path through which the fluid can flow and which is fluidically connected to the first flow path at a first connection point located in the first flow path upstream of the throttle and downstream of the pump; and a second consumer which is arranged in the second flow path and can be supplied with the fluid via the second flow path.

Abstract: A lubricant supply for a powertrain in an electrically driven motor vehicle has a hydraulic oil pump, which can be driven by a drive actuator, a lubricant supply point and a lubricant reservoir. The hydraulic oil pump can generate a first lubricant volume flow from the lubricant reservoir to the lubricant supply point and a second lubricant flow volume from the lubricant supply point or an additional lubricant supply point in the lubricant reservoir. The drive actuator is an electric motor. The lubricant supply point is arranged in a traction motor with a rotor shaft and a motor housing. The additional lubricant supply location is disposed in a traction transmission. The lubricant supply points can be supplied with lubricant by way of the first lubricant volume flow.

Abstract: A system (18) for a transmission (16) of an electric vehicle, including: a pump (34), accumulator (36), control valve (38), sensor (40), check valve (42), and sequence valve (44). The accumulator (36) stores fluid from the pump (34). The control valve (38) modulates pressure to the transmission (16) from the pump (34). The sensor (40) is between the control valve (38) and transmission (16) and generates a signal. The check valve (42) is between the accumulator (36) and pump (34). The sequence valve (44) has: an input (56) communicating with the pump (34), an output (58) communicating with the accumulator (36), a closed position (44A) wherein flow is interrupted between the accumulator (36) and pump (34), and an open position (44B) wherein fluid from the pump (34) can be stored in the accumulator (36); and is movable between positions (44A, 44B) in response to changes in the sensor (40) signal.

Abstract: A number of variations may include a clutch apparatus having at least one clutch and having an actuating device for actuating the clutch, the actuating device being movable from an opening position, in which the clutch is open, into a closing position, in which the clutch is closed. The actuating device can be locked with form-fit action in the closing position or opening position.

Abstract: The present invention relates to a freewheel (4) having an inner ring (38), an outer ring (40) and at least one wedging element (48) between the inner ring (38) and the outer ring (40), which can be moved from a wedging position, in which the wedging element (48) prevents rotation of the outer ring (40) relative to the inner ring (38) in a first circumferential direction (24), into a release position, in which the outer ring (40) can be rotated in an opposite, second circumferential direction (26) relative to the inner ring (38), wherein the wedging element (48) is preloaded into the wedging position by means of a spring element (64). The spring element (64) has an elongate spring body (66), which extends in a radial plane and has a corrugated profile in the radial direction (20, 22). The present invention furthermore relates to a freewheel arrangement (2) having a freewheel (4) of this kind.

Abstract: A starter freewheel is provided. The starter freewheel has a first race, a second race, a wedging gap formed between the first and second races, at least one wedging element arranged in the wedging gap, and at least one further component. The further component is in rotary drive connection with one of the races. The component is formed by at least two sheet-metal parts connected to one another in sandwich-fashion. A freewheel arrangement having a starter freewheel of this kind is also provided.
