Embodiment Construction

[0035] exist figure 1 shown in the motor vehicle wheel 16 ( Figure 7 ) of the rim 1. The rim 1 has a rim ring 3 on the outside, viewed in the radial direction, and has spokes 5 adjoining the rim ring 3 on the inside, viewed in the radial direction, and are integrally and integrally connected to the rim ring 3 . The tire 17 ( Figure 7 ). The spokes 5 of the rim 1 constitute the rim ring 3 and the motor vehicle 18 ( Figure 7 ) between the hubs. figure 1 The rim 1 shown in is here made of aluminum, for example. However, the rim can also be produced from any other suitable material, for example also from steel or from a light metal other than aluminium.

[0036] In order to explain the structure of the rim ring 3 shown in the drawings, in Figure 6 A partial section of the rim ring 3 is also shown in . It follows from this that the rim ring 3 is designed here as a grooved rim ring. Thus, the rim well 10 of the rim ring 3 has here, viewed in the transverse rim direction...

Abstract

The invention relates to a rim for a vehicle wheel, in particular for a motor vehicle wheel. According to the invention, in order to optimize the rolling noise of the vehicle wheel (16), especially in order to specifically adjust and / or change at least one resonant frequency of the vehicle wheel (16), the wheel rim (1) includes at least one locally restricted rigidity-modified area (6) on and / or in which the rigidity of the wheel rim (1) is different from the rigidity in an immediately adjacent wheel rim zone and / or different from the rigidity in a basic state of the wheel rim (1) in said zone or the state thereof in said zone at the time of production.

Description

technical field [0001] The invention relates to a rim for a vehicle wheel, in particular a motor vehicle wheel, and a method for optimizing the rolling noise of a vehicle wheel, in particular a motor vehicle wheel. Background technique [0002] An important aspect in vehicle development, especially in motor vehicle development, is the optimization of vehicle noise. This also includes optimization of the rolling noise of the vehicle, which is mainly produced by the rolling of the vehicle wheels on the roadway. This rolling noise is usually enhanced by resonance, for example by tire toroidal resonance which may be caused by vibrations of the air column in the cavity of the vehicle wheel. In this case, the rim of the vehicle wheel is usually also one of the solid bodies participating in this vibration system. Furthermore, since the vibrations of the rim are introduced into the vehicle interior by structure-borne sound, the vibrations significantly affect the background noise ...
