A stator holding plate () for a wheel hub drive system, in particular for an electric and/or hybrid vehicle, which stator holding plate has a stator fastening portion (S) for the fastening of a stator () of an electric motor to the stator holding plate () and has an inverter fastening portion (I) for the fastening of an inverter () to the stator holding plate (). A wheel hub drive system equipped with the same.

Stator holding plate with inverter fastening function

A wheel hub drive system with an electric motor that can be arranged inside a wheel rim, whereby the electric motor is formed by rotor that is at least indirectly joined to a wheel hub and by means of a stationary stator that can be supplied with alternating current. With an eye towards obtaining more space for the vehicle occupants, it is proposed to arrange the converter with its entire power electronics unit on the stator so that the wheel hub drive system can be operated with direct current from the battery of the vehicle, or else no alternating current lines have to be laid in the vehicle. Consequently, the alternating current is generated by the converter that is arranged in a converter housing attached axially next to the stator.

Wheel hub drive system

A chassis actuator adjusting a movably mounted component of a chassis, which has a first actuator component connected to the movably mounted component and a second actuator component connected to a fixed chassis component. The actuator components are adjustable axially by a ball screw that has a threaded spindle and a nut which runs on spindle. The nut is driveable by a drive motor that has a rotor coupled to the nut and a fixed stator arranged axially symmetrically with respect to the nut. The rotor is coupled to the nut by a wrap spring which radially surrounds the nut and via which the nut is rotated during rotation of the rotor and which forms a brake device. The brake device can be actuated by an external chassis force which acts on and rotates the nut and builds up a friction moment that counteracts the rotation of the nut.
