DRIVE UNIT FOR A VEHICLE WHEEL, VEHICLE WHEEL, AND METHOD FOR DRIVING A VEHICLE WHEEL

摘要

The invention relates to a drive unit (3) for a vehicle wheel (1), wherein the drive unit (3) comprises an electric machine having a stator (12) and a rotor (7), a central shaft (9), at least one first wheel bearing (8), and at least one braking device, wherein the stator (12) is arranged coaxially with the central shaft (9) and is fastened to the central shaft, wherein the rotor (7) is coaxial with the central shaft (9) and rotatably supported about the stator (12) by means of the at least one first wheel bearing (8), wherein the rotor (8) has a rotor housing (21), wherein means for producing a magnetic field having alternating polarity are arranged on a first section (22) of the rotor housing (21) in the circumferential direction of the rotor (7), wherein a second section (23) of the rotor housing (21) is designed as a braking surface that interacts with the braking device, wherein the electric machine is a direct-current machine and the first and second sections (22, 23) of the rotor housing (21) are mechanically connected to each other by means of a third section (28), wherein the third section (28) prevents or reduces heat transfer between the second and first sections (22, 23). The invention further relates to a vehicle wheel (1) and to a method for driving a vehicle wheel (1).
