1. A wheel, comprising:
- an electric drive in the wheel, said electric drive comprising a rotor that is rotatable around a central shaft and a stator that is situated at a smaller distance from the shaft than the rotor, the stator being mounted on a circumferential surface of a central carrying member, the circumferential surface extending in the direction of the central shaft, the carrying member having recesses arranged in a radial surface thereof that is oriented transversely to the central shaft; and
a clamping member arranged on said radial surface of the carrying member, the clamping member being configured to close off the recesses so as to allow cooling liquid to pass through the recesses, the clamping member forming an accommodation space in which operating and control electronics are housed, and the carrying member and the clamping member forming a cooling body configured to cool the electronics.

15. A wheel, comprising:
-
an electric drive in the wheel, said electric drive comprising a rotor that is rotatable around a central shaft and a stator that is situated at a smaller distance from the shaft than the rotor, the stator being mounted on a circumferential surface of a central carrying member, the circumferential surface extending in the direction of the central shaft, the carrying member having recesses arranged in a radial surface thereof that is oriented transversely to the central shaft; a liquid cooling system to cool the electric drive; operating and control electronics including transistors for current control and programmable operating modules for an operating system; a cooling body configured to cool the electronics and to seal off cooling liquid from the electronics; and a clamping member arranged on said radial surface of the carrying member, the clamping member being configured to close off the recesses so as to allow the cooling liquid to pass through the recesses, the clamping member forming an accommodation space in which said operating and control electronics are housed, and the carrying member and the clamping member forming said cooling body configured to cool the electronics. - View Dependent Claims (16, 17)
