Differential assembly and driving assembly with a differential assembly

摘要

A differential assembly is disclosed, and more particularly a differential assembly for a motor vehicle driving axle drivable by an electric motor. The differential assembly comprises a driving gear; a differential drive with an input part and two output parts, wherein the output parts are drivingly connected to the input part and, relative to one another, have a differential effect; a coupling which is arranged effectively between the driving gear and the differential drive, wherein, in a closed condition of the coupling, torque is transmitted from the driving gear to the differential drive and, in an open condition of the coupling, a transmission of torque is interrupted; a controllable actuator for actuating the coupling and a sensor for determining at least three switched positions of the coupling. Furthermore, a driving assembly with such a differential assembly is also disclosed.

1. A differential assembly, comprising:
a driving gear; a differential drive with an input part and two output parts, wherein the output parts are drivingly connected to the input part and, relative to one another, have a differential effect; a coupling effectively arranged between the driving gear and the differential drive, wherein, in a closed condition of the coupling, torque is transmitted from the driving gear to the differential drive and, in an open condition of the coupling, a transmission of torque is interrupted; a controllable actuator for actuating the coupling, wherein the actuator comprises an electromagnet and an axially displaceable piston, and wherein the actuator is configured to generate a current signal representing a coil current of the electromagnet; a sensor for determining at least three switching positions of the coupling, wherein the sensor is configured to generate a sensor signal representing a switching position of the coupling; and an electronic control unit which is configured to receive said sensor signal from said sensor, to evaluate the sensor signal thereby taking into account the current signal of the electromagnet, to generate an evaluated sensor signal, and to control the electric motor based on said evaluated sensor signal.
