A positive-locking clutch for a motor vehicle comprises a coupling element with a toothing, a rotatable counterpart element with a counterpart toothing, and an electromagnetic actuator. The coupling element can be moved by means of the electromagnetic actuator between a disengaged position and an engaged position, and wherein the toothing of the coupling element is meshed with the counterpart toothing of the counterpart element in the engaged position. Even after the engaged position of the coupling element has been fully reached, a backlash is provided between the toothing of the coupling element and the counterpart toothing of the counterpart element.

Positive-locking clutch

A clutch for a motor vehicle, preferably for engaging and disengaging a drive train for all-wheel drive vehicles, comprises a first shaft, a second shaft arranged coaxially to the first shaft, a clutch sleeve which is moveable in the axial direction relative to the first shaft and the second shaft for causing a form-fit coupling or decoupling of the first shaft and the second shaft, and a coil which can be powered, wherein a plurality of engagement bodies are connected rotationally fixedly to the first shaft, wherein the coil which can be powered is arranged coaxially to the axial direction, wherein by powering the coil, the clutch sleeve can be moved in the axial direction, wherein by moving the clutch sleeve in the axial direction, the engagement bodies can be pressed over part of their height into receivers, and wherein the receivers are connected rotationally fixedly to the second shaft.

Clutch

A method for operating a powertrain of a motor vehicle with two vehicle axles which can be driven by separate drive assemblies, wherein at least one of the two vehicle axles can be driven by an electromotive drive assembly, and wherein the at least one vehicle axle has two wheels and at least three axle portions, wherein a first axle portion has a first wheel, wherein the first and a second axle portion are coupled by a differential gear, wherein the second and a third axle portion are arranged so they can be connected together by a clutch, and wherein the third axle portion has a second wheel. During drive mode of the motor vehicle with the clutch open, the electromotive drive assembly is held at a standby rotation speed under active regulation by an electric drive control unit, wherein the standby rotation speed tracks a synchronization rotation speed.

Method for operating a powertrain

A hydraulic system is presented with a hydraulic fluid, with a work element actuable by the fluid, with a fluid pump for the application of a fluid pressure to the fluid, with the fluid pump being operable to generate a reference depression in the system, and with a pressure sensor for the measurement of the fluid pressure which is in communication with a control unit which is designed to carry out a calibration of the pressure sensor with reference to the reference depression.
