Abstract: A basic housing for a wheel hub motor, which can be produced cost-effectively even in large quantities is provided. To this end, a basic housing (5) for a wheel hub motor (2) is proposed, wherein the basic housing (5) has a receiving area (14) for a stator (6), having at least one stator housing section (11) for arranging the stator (6), wherein cooling channels (15) for cooling the stator (6) are arranged in the stator housing section (11), and having a cooling device (26), wherein the cooling device (26) forms the cooling channels (15), wherein the stator housing section (11) is made of a plastics material, and wherein the cooling device (26) is at least partially embedded as a first insert in the plastics material in the stator housing section (11).

Abstract: 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.

Abstract: A stator holding plate (1) 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 (103, 105) of an electric motor to the stator holding plate (1) and has an inverter fastening portion (I) for the fastening of an inverter (30) to the stator holding plate (1). A wheel hub drive system equipped with the same.

Abstract: 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.

Abstract: A drive system, in particular a drive system of a wheel hub, for a motor vehicle, in particular an electric and/or hybrid motor vehicle, the drive system including an electric motor. In order to prevent moisture from accumulating in an internal chamber (1) of the drive system, the drive system includes a ventilation device (20) for aerating and de-aerating the interior chamber (1) of the drive system. The ventilation device (20) includes at least one air supply device (21) for supplying air into the internal chamber (1) of the drive system and at least one air removal device (22) for removing air from the internal chamber (1) of the drive system.

Abstract: A drive system, in particular for an electric and/or hybrid vehicle, including a static part (S) and a rotatably mounted part (D) and also an electric motor with a stator (1) and rotor (2), wherein the static part (S) includes the stator (1) and the rotatably mounted part (D) includes the rotor (2). To identify a tilt of the bearing or of the rotor, in particular in order to prevent abrasion of the rotor (2) against the stator (1) and/or to identify damage in the system, the drive system includes a bearing tilt detection system for detecting a bearing tilt of the rotatably mounted part (D), wherein the bearing tilt detection system evaluates data of the electric motor and/or of at least one sensor (10, 20, 30) with regard to whether a bearing tilt is present. The invention also relates to an electric and/or hybrid vehicle.
