Abstract
A pneumatic vehicle tire of a radial type of construction with a profiled tread (1), sidewalls (3), bead regions (2) and an airtight inner layer (4), which forms the inner side (4a) facing the interior space of the pneumatic vehicle tire, ribs (6) being formed on the inner layer (4), having been imprinted in it by a heating bladder introduced into the interior of the tire during the vulcanizing of the pneumatic vehicle tire in a tire heating mold, and a sound absorber (5) being provided so as to extend in an annular manner on a circumferential region (4b) of the inner side (4a) opposite from the tread (1). Grooves (7) have been formed by the heating bladder at least in a partial region of the circumferential region (4b) of the inner layer (4a) on which the sound absorber (5) is provided.
Claims14
A pneumatic vehicle tire of a radial type of construction comprising a profiled tread, sidewalls, bead regions and an airtight inner layer which forms an inner side facing an interior space of the pneumatic vehicle tire, wherein ribs are formed on the airtight inner layer by being imprinted during the vulcanizing of the pneumatic vehicle tire in a tire heating mold, and wherein a sound absorber is provided which extends in an annular manner on a circumferential region of an inner side opposite from the profiled tread;
- wherein the ribs are formed on an inner side of the airtight inner layer;
- grooves are only formed on the circumferential region of the inner side opposite from the profiled tread and positioned between the sound absorber and the inner side opposite from the profiled tread of the circumferential region;
- the ribs are formed on the inner side at least partially within the circumferential region;
- the sound absorber comprises a thermoplastic foam and is adhesively attached to the inner layer in at least the circumferential region where the grooves are formed by an adhesive bonding layer;
- the sound absorber having a constant width b1 over the circumference of the tire and having a thickness between 5% and 20% of the constant width b1.
