Abstract

A wheel for a motor vehicle comprises a rim having an outer radius and a wheel spider including a radially inner hub and a plurality of spokes extending from said hub towards said rim. At least one through-hole extends, with respect to the wheel axis, in a circumferential direction through at least one of said spokes. A radially outer edge of said through-hole or of an outermost of said through-holes is located at maximum at 75%, preferably at maximum at ⅔, of said outer radius of the rim measured at a wheel spider side of the rim.

Abstract

A vehicle wheel having a rim, or a rim of a vehicle wheel, is provided wherein the rim consists of a fiber-reinforced plastic material in the form of several layers of a fiber-reinforced semi-finished plastic product. The layers are shaped to form a finished component in a press while heat is supplied. The rim conventionally consists of a rim well, whose two sides are adjoined by a rim shoulder, which transitions into a rim flange. The rim well is formed by several layers of a base laminate, which extends to the rim flange, between which layers further layers are inserted in the area of the rim shoulder as well as of the rim flange. The further layers have an essentially tangential fiber alignment.

Abstract

The invention relates to a vehicle wheel made from composite fibre material with continuous fibre strands, at least consisting of a rim and of a rim spider or wheel spider which forms spokes and contains a pre-shaped core which is covered at least in regions by composite fibre material. The core here comprises at least the wheel hub region having one or more through holes for wheel screws, while the composite fibre material covering said core at least in regions is represented by at least two wheel-spider discs which are pre-shaped or are formed within the scope of the production of a core formed from plastic, by coating said core, with the core being located between said wheel-spider discs, and therefore the wheel spider constitutes a sandwich structure which is connected to the rim at least via the wheel-spider discs.

Abstract

The invention relates to a vehicle wheel consisting of fibre-reinforced plastic, having a rim spider or a wheel disc assuming the function of spokes and a hub section which is central with respect to the wheel rotation axis, has a greater length in the rotation axis direction than the wheel disc in the region of the spokes, and only extends over part of the diameter of the wheel disc, and in which bores lined with bushings are provided to receive wheel screws or wheel bolts for fastening the wheel to a wheel hub of the vehicle. The hub section is (also) formed by a hub component that is produced separately from the wheel disc, to which hub component the wheel disc, which preferably likewise has a hub section, is connected in a bonded manner.

Abstract

The invention relates to a vehicle wheel with a rim or rim of a vehicle wheel comprising fibre-reinforced synthetic material in the form of a plurality of layers (11a, 11b, 12a, 12b, 21, 31) of a fibre-reinforced synthetic semi-finished product, which is formed in a press device by supplying heat to the finished component, wherein the rim consists, as usual, from a rim bed (1), both sides of which are adjoined by a rim shoulder (2), which passes into a rim flange (3), wherein the rim bed (1) is formed by several layers (11a, 11b, 12a, 12b) of a basic laminate (10) extending up to the rim flange (3), between which layers are inserted further layers (21, 31) in the region of the rim shoulder (2) and of the rim flange (3). Preferably the further layers (21, 31) have an essentially tangential fibre orientation.
