COVERING OF VEHICLE TYRES WITH LIGHT-ALLOY RIMS DURING PROLONGED TRANSPORTATION

摘要

A cover for light-metal wheels during protracted transport is provided by a round, closed, and inherently rigid film moulding which engages over the outer face of the light-metal rim beyond the rim flange in a surface-covering manner. The cover is positively fastened centrally in wheel-side recesses by elevations integrally formed in the film moulding. A centering bore, known per se, is utilized for a more secure central fastening of the film moulding to the vehicle wheel. The film moulding carries, in its center, a cylindrical extension which is pressed into the centering bore of the vehicle wheel. The inner surface of the centering bore may have a circumferential groove of preferably trapezoidal cross section. The cylindrical extension of the film moulding carries circumferentially a plurality of catch noses which correspond in axial position and cross-sectional shape to the wheel-side circumferential groove and engage positively into the latter. To make pressing-in easier, a plurality of axially running grooves are made on the circumference of the cylindrical extension. The film moulding is designed with a wavy cross section in the part covering the rim outer face, the center line of the waves themselves likewise being arcuately curved axially outwards.
