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 drive train includes a drive element, an output element and a thermal overload safeguard. The thermal overload safeguard is configured in such a way that there is a connection between the drive element and the output element below a critical temperature, and the drive element and the output element are decoupled mechanically from one another above the critical temperature.

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 transmission for a motor vehicle is provided. The transmission has a hydraulically or electrically operable gearshift sleeve, a clutch pack, an input shaft, and an output shaft, a gearshift sleeve, a gearshift sleeve claw, and an opposing output claw associated with the output shaft. The gearshift sleeve can be moved from an initial position into a first position, in which the gearshift sleeve transfers an axial force by way of the first ramp element and the second ramp element to the clutch pack for synchronization of the disks, and into a second position, in which the gearshift sleeve claw is connected to the output claw interlockingly in the direction of rotation and thus the input shaft and the output shaft are interlockingly coupled. A method for shifting such a transmission is also provided.

Abstract: A transmission, in particular for a motor vehicle, is provided. The transmission has a hydraulically or electrically operable gearshift sleeve, a dutch pack, an input shaft, and an output shaft, which are rotatably mounted about an axis of rotation, a first ramp element, and a second ramp element. The gearshift sleeve has a gearshift sleeve claw, and the output shaft has an output claw, which is arranged so as to lie opposite. The gearshift sleeve can be moved from an initial position into a first position, in which the gearshift sleeve transfers an axial force by way of the first ramp element and the second ramp element to the clutch pack for synchronization of the disks, and into a second position, in which the gearshift sleeve claw is connected to the output claw interlockingly in the direction of rotation and thus the input shaft and the output shaft are interlockingly coupled.

Abstract: A coupling assembly is provided for a transmission assembly, in particular for a multiple spider planetary gear transmission, wherein the transmission assembly has two speed-change gear units coupled to each other. A first shaft and a second shaft are coupleable with one of the speed-change gear units, wherein by blocking of one of the shafts two shifting stages of the transmission assembly are shiftable. A third shaft is provided as well as a first shifting element and a second shifting element, each of which couples the first shaft and the second shaft with the third shaft. A third shifting element is provided which can brake and/or block the third shaft.
