Problems solved by technology

Another reason may be that the thermal insulation caused by the foam insert in the prior art is still problematic
Thermal insulation causes the heat generated by the tire tread to be dissipated to a lesser extent inside the tire, resulting in increased tire wear

Embodiment Construction

[0046] A vehicle tire 1 made of rubber or a rubber compound has a tread band 2 on the outside of which a tread 3 of the vehicle tire 1 is formed. Two sidewalls 4, 4.1 are formed on the tread band 2 and have a bead at the end of each sidewall. For simplicity, the car tire 1 is described without reinforcements or carcass. Similarly, the bead cores in the beads 5, 5.1 are also not shown. like figure 1 As shown, a car tire 1 is mounted on a rim 6 of a wheel 7 . The beads 5, 5.1 are located on the rim and are pressed against the adjoining rim flange 8, 8.1 by the inner tire pressure.

[0047] The foam insert is arranged in the vehicle tire 1 and is indicated as a whole by the reference number 9 . The foam insert 9 is attached to the inner side 10 of the tread band 2 and to the inner side of the side walls 4, 4.1. When the automobile tire 1 rotates, the foam insert 9 in contact with it also rotates with it. The foam insert 9 fills approximately 30% of the cavity 11 of the vehi...

Abstract

The invention discloses an elastic vehicle tire having a cavity (11) bounded by a tread band (2) supporting the tread (3) and side walls (4, 4.1) adjoining the tread band on both sides ), and a foam insert (9) in contact with the inner side (10) of the tread band (2). Each side wall has a bead (5, 5.1) provided at a free end for fitting around a flange (8, 8.1) of a rim (6) of a wheel (7). The foam insert (9) fills part of the cavity (11) and acts as a noise dampener. Between the foam insert and the inner side of the automobile tire adjacent to the tread band or within the foam insert, at least one heat dissipation insert is provided which extends partially across the width of the tread band to remove heat from this area and The side walls extend in the region of the side walls in which heat can be dissipated from the heat dissipation insert into the cavity.

Description

technical field [0001] The invention relates to a vehicle tire having a cavity enclosed by a tread band supporting the tread and sidewalls adjoining the tread band on both sides, and a foam insert in contact with the inner side of the tread band. Each side wall has a bead provided at a free end for fitting around the flange of the rim of the wheel. A foam insert fills part of the cavity and acts as a noise dampener. Background technique [0002] Such car tires for cars, trailers and semi-trailers are also known as pneumatic car tires. This car tire is a tire with a hollow cavity, and its stability depends critically on the air pressure injected into the cavity. The cavity of this automobile tire is formed by a tread band supporting the tread and sidewalls integrally formed on both sides thereof. Each side wall has a bead at a respective free end through which a tire mounted on the rim of the wheel abuts the rim and the rim flange. In tubeless tires, the bead seals agains...
