Vehicle wheel with an especially single-piece rim and tubeless tire suitable for emergency use, and a method for mounting a vehicle wheel having an emergency support surface

摘要

Inside the tire there is an emergency running ring support held on the rim. The tire sidewalls have rim-fastening beads which are resiliently-variable in circumferential length. An Independent claim is included for the method of mounting the tire (3). The emergency running support ring (11) is first arranged on the rim (1). A tire bead (6) is stretched to move it over the support ring. The bead is allowed to relax before fastening to the rim. Preferred features: The tire is fastened onto the rim with its beads radially inside the outer surface of the rim, preferably in its axial end faces. The rim has an annular chamber (10) designed to accept and hold the tire. The emergency running surface (14) corresponds roughly with the axial position of the bead held in the rim. Dimensional dispositions and rubber hardnesses are detailed. A detachable filler ring (12) is included. Resilience data are included. A number of variants based on these principles are described. The emergency surface is resiliently-coated.
