Definitions

  • Wheel especially light alloy wheel
  • the invention relates to a wheel, in particular a light alloy wheel for motor vehicles, according to the preamble of claim 1.
  • Alloy wheels are very popular because, in addition to an increased overall aesthetic appearance of the motor vehicle, other technical advantages can be achieved.
  • a wheel is known from WO 01 / 17799A1, which enables a further weight reduction due to a special structure.
  • This known wheel has a wheel rim which is provided with a rim outer bed and a rim inner bed.
  • the outer rim bed serves together with a profile segment
  • the profile segment consists of separately manufactured half-shells, which are made of plastic, for example, which means that a lightweight wheel can be built that is particularly strong in hazardous areas.
  • the relatively high manufacturing outlay is disadvantageous here. If it is designed as a half-shell, the profile segment must be manufactured separately and then connected to the rim by gluing or welding,
  • the invention was therefore based on the problem of improving a wheel of the type mentioned at the outset in such a way that the manufacturing outlay is reduced.
  • the invention is based on the idea of requesting the plastic directly on the wheel. In this way, it is possible to maintain the weight and strength advantages of the known wheel, in which the rim outer bed is formed at least in sections by pre-made profile segments, but to reduce the manufacturing effort considerably. With this concept, established manufacturing processes, such as the injection molding process, can be used.
  • CONFIRMATION S OP can be provided with spoke cavities to save weight, which are then filled with plastic.
  • the resulting plastic core is led radially out of the immediate area of the wheel spider so that it is led upwards into the area of the outer rim bed and serves directly as a tire seat.
  • Such wheels can thus be produced inexpensively, and excellent strength values can be achieved.
  • the wall thicknesses of the spokes can be reduced further, as a result of which a considerable weight reduction with constant strength can be achieved.
  • foamed plastics with which additional weight savings can be achieved. Compared to previous designs, this can be at least 1 to 2 kg per wheel.
  • the foamed plastic has a skin on its surface, which thus ensures a smooth and optimal tire fit and, in particular, also enables an airtight seal to mature without additional measures.
  • the plastic is a reinforced, in particular fiber-reinforced plastic, for example a glass fiber or carbon fiber reinforced plastic, the required strength properties of the wheel can be achieved particularly easily and at the same time saving weight.
  • Plastics especially polyamide or a polycarbonate. Mach Following is a provisionssb 'EXAMPLE explained in more detail with reference to FIG.
  • a wheel 1 is constructed in a manner known per se from a wheel rim 10 and a wheel star 20.
  • the wheel rim 10 has an inner rim bed 16 and an outer rim bed 14. These merge axially outward into a rim flange 18 and a rim flange 12.
  • a tire 50 is held between the inner rim 18 and the outer rim 12, which sits on the inner rim 16 and the outer rim 14 and rests laterally on the inner rim 18 and the outer rim 12.
  • the wheel rim 10 merges into the wheel star 20, which has a plurality of spokes 22.
  • the spokes 22 are designed as hollow spokes and each have a spoke cavity 24.
  • the surface of the plastic foam forms a skin 32 and thus offers a smooth and optimal fit for the tire 50.
  • the strength of the spoke 22 can be increased, which is particularly the case with light metal wheels is a big advantage because it improves their impact behavior.
  • the risk of damage when driving over a curb or a pothole is reduced with the wheel 1 according to the invention.

Abstract

L'invention concerne une roue, notamment une roue en métal léger, destinée à des véhicules automobiles et comprenant sensiblement une étoile de moyeu (20) et une jante (10). La jante (10) présente une embase interne (16) et une embase externe (14) qui se transforment respectivement en un rebord interne (18) et un rebord externe (12). L'embase externe (14) est constituée, au moins par sections, d'une matière plastique, la matière plastique (30) étant directement moulée sur la roue (1).
