Problems solved by technology

[0008] Although the conical centering surface provides an enlarged area for the introduction of the clamping force, this design also results in a thinner wall thickness of the wheel disk especially in the highly loaded areas and thus the fiber composite material weakened
[0009] In addition, this fastening solution requires high manufacturing and installation work

Embodiment Construction

[0042] figure 1 A wheel rim 1 according to the invention with a rim sole 2 and a wheel disk 3 made of carbon-fibre-reinforced plastic is shown in a partial sectional view extending as far as the wheel axis 4 . For the sake of simplicity, a general cross-sectional view of the rim 1 is not used. In the assembled state, the wheel rim 1 engages with a schematically shown wheel hub 5 of the motor vehicle. The hub connection of the rim 1 is designed as a central thread, which actuates a threaded wheel fastening nut 6 and an annular clamping disk 7 as fastening element.

[0043] The wheel disk 3 has a central opening 8 in which the hub 5 is seated in the assembled state. The central opening 8 has a conical centering surface 9 which is inclined relative to the wheel axis 4 and extends over the entire wall cross section of the wheel disk 3 .

[0044] The carbon-fibre-reinforced plastic for the rim 3 contains a surface-formed fiber layer 10 into which continuous reinforcing fibers ar...

Abstract

The invention relates to a wheel rim with a wheel disc (3) made of fiber composite material and fixing elements for fixing the wheel disc (3) on a wheel hub (5) of a vehicle, the wheel disc (3) having at least one An opening (8) for accommodating the hub (5), said opening (8) being configured with a conical centering surface (9) for correspondingly accommodating a fixing element. The invention proposes that the reinforcing fibers of the fiber composite material are arranged in a planar fiber layer (10), and that at least a part of the fiber layer (10) is arranged perpendicularly to the centering surface (9) of the wheel disc (3) in the opening (8 ) in the edge region (12).

Description

technical field [0001] The invention relates to a wheel rim with a wheel disc made of fiber composite material and fastening elements for fastening the wheel disc to a wheel hub of a vehicle, the wheel disc having at least one opening for receiving the wheel hub, The opening is configured with a conical centering surface for mounting a fixing element. Background technique [0002] A wheel disk made of fiber composite material is known, for example, from document DE 1939910 A. This document discloses a method for producing drive wheels for vehicles from fiber-reinforced plastic, in which in highly stressed areas of the wheel disc or wheel carrier the reinforcing fibers are arranged corresponding to the distribution of the stresses occurring Circular and arranged radially with respect to the wheel axis. In order to increase the strength, additional fiber inserts are arranged one above the other in this region. The openings for the hubs and the mounting of the hubs or fixing...
