Problems solved by technology

[0006] Furthermore, it has been found that the hitherto known undercut connection of the rim base and the spokes requires additional effort in order to achieve a sufficient material bond between the rim base and the spokes during the subsequent reinforcement of the prefabricated rim.

Embodiment Construction

[0043] figure 1 A wheel rim 1 . 1 according to the invention according to a first exemplary embodiment is shown, which comprises a closed-surface spoke 2 made of carbon fiber composite material and a rim sole 3 made of carbon fiber composite material. The wheel spoke has two partial layers 4 , 5 made of carbon fiber composite material in its surrounding edge region. The two partial layers 4 , 5 are produced along the edge region of the wheel spoke 2 , for example by circumferentially longitudinal sectioning in the carbon fiber composite material.

[0044] In contrast to the predominantly radially extending spoke bodies, the partial layers 4 , 5 are arranged substantially axially extending and diverging opposite one another. The two partial layers each have a joint region 6 , 7 which rests on the rim base 3 following the contour of the rim base of the rim and is connected to it. The joining region 6 of the inner partial layer 4 extends towards the inner rim edge 8 of the rim ...

Abstract

The invention relates to a wheel rim having a rim base (3) made of fiber reinforced material and a wheel disk (2) connected to the rim base (3) in a radial edge section. The aim of the invention is to improve the connection between the rim base (3) and the wheel disk (2) and to provide a method for producing a wheel rim having an improved connection between the rim base (3) and the wheel disk (2). The radial edge section of the wheel disk (2) comprises at least two partial layers (4, 5) in which contoured joining zones (6, 7) which extend substantially axially, are provided, said joining zones being connected to the rim base (3) over their entire surface.

Description

technical field [0001] The invention relates to a wheel rim having a rim base made of fiber composite material and spokes, wherein the spokes are connected to the rim base in radial edge regions. [0002] The invention also relates to a method for manufacturing a wheel rim. Background technique [0003] Wheel rims are produced at least partially from fiber composite materials, especially in the motor vehicle sector due to the need for lightweight construction. The components of the rim, such as the rim base and the spokes, are prefabricated according to specific requirements from specific prefabricated parts of different materials and then joined together. Here, the parts are connected to each other at specially designed joint areas, wherein the connection must withstand enormous loads. [0004] From the document DE 10 2010 010 512 A1, connections of rim bases and spokes made of fiber composite material are known, in which the connections are advantageously formed by a for...
