19. Hybrid rim (10) according to claim 9, wherein the fiber composite plastic is a glass fiber-reinforced plastic (GFK) or a carbon fiber-reinforced plastic (CFK).

20. Rim (10) according to claim 16, wherein the light metal is an aluminum alloy.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0031] Further details and advantageous developments of the disclosure will be acquired from the following description taken in conjunction with the drawings, in which

[0032] FIG. 1 shows a schematic perspective view of a hybrid rim according to the disclosure with a rotor bell as viewed from the outside

[0033] FIG. 2 shows a schematic perspective view of a hybrid rim according to the disclosure with a rotor bell as viewed from the inside, and

[0034] FIG. 3 shows a schematic cross-section through the hybrid rim with rotor bell according to the disclosure.

DETAILED DESCRIPTION

[0035] If same reference numerals are used in the figures, they designate the same parts, so that in order to avoid repetitions, an already described component will not be referred to anew in every description of figures.

[0036] The hybrid rim 10 of a wheel provided with a wheel hub motor shown in FIGS. 1 to 3, in particular of a motor vehicle, includes a rim base 12, an outer and an inner rim flange 14, 16 and a wheel disc having a center hole 18, mounting holes 20 and spokes 22.

[0037] According to the disclosure, the hybrid rim 10 includes a non-metal part and a metal part, in which the rotor housing of the wheel hub motor at least partially forms the metal part of the hybrid rim 10.

[0038] The rim base 12 of the hybrid rim 10 is annularly configured, in which the wall 24 of the rim base 12 is composed of an annular outer non-metal part 24a and an annular inner metal part 24b, with forming a composite bonding.

[0039] The part 24a, made of a non-metal, of the rim base 12 and the rim flanges 14, 16, also made of a non-metal, are formed from one piece.

[0040] The wheel disc can also be produced from a non-metal, and either formed in one piece with at least one other non-metal part or, as a separate part, connected with at least one other non-metal part.

[0041] The non-metal part can be a carbon fiber-reinforced plastic (carbonfaserverstarkten Kunststoff, CFK).

[0042] In the present case, the rotor housing made of metal is configured in the manner of a rotor bell, which consists of hood 28 and the wall 24bmade of metalof the annular rim base 12, in which the hood 28 of the rotor housing is formed in the interior room of the hybrid rim 10 between the wall 24 of the annular rim base 12 and the hole circle 26 having the mounting holes 20, and is arranged on the inner side to the wheel disc having spokes 22.
