Problems solved by technology

In the case of industrial mass production, the necessary avoidance of conflicts in this case leads to undesirably higher costs and more time-consuming
[0007] This disadvantage is overcome by fixing the muffler to the inner surface of the pneumatic tire, however in this case in case of minor damage, for example due to piercing nails or debris, the pneumatic tire is no longer repairable and has to be replaced
In addition, when the muffler is still functional and the pneumatic tire is worn, or the pneumatic tire is still functional and the muffler is worn out, a full set replacement is also required

Embodiment Construction

[0024] first look at figure 1 , which schematically represents a partial cutaway perspective view of a first embodiment of a tubeless pneumatic tire for automobile wheels according to the present invention. The pneumatic tire generally designated with the reference numeral 1 comprises a tread portion 2 radially on the outside for the rolling of the pneumatic tire 1 on roads, two sidewall segments 3 and two radially inward bead Segment 4, when the pneumatic tire is mounted on the rim and then inflated, the bead segment 4 bears tightly against the rim.

[0025] The pneumatic tire 1 surrounds, by its various sections 2-4, a generally annular or torus-shaped inner chamber 5, which extends in the circumferential direction of the pneumatic tire 1. When the assembled pneumatic tire 1 rotates and impacts on the pneumatic tire due to road unevenness, it may be excited to form resonant sound waves in the inner cavity 5, and they propagate along the circumferential direction and the rad...

Abstract

The present invention relates to a pneumatic tire (1) for reducing a tire noise having an annular cavity (5) and at least one acoustic damper (6), situated in the cavity, made of an open-celled material. The acoustic damper (6) is removably connected to an inner face (7) of the pneumatic tire facing toward the cavity (5) using at least one removably connectable connection device (8, 9, 10, 13). Furthermore, the invention provides a wheel rim having a pneumatic tire (1) drawn thereon, an annular cavity (5) being shaped between wheel rim and pneumatic tire, as well as at least one acoustic damper (6) made of open-celled material, which is situated in the cavity, which is distinguished in that the acoustic damper is removably connected on an inner face facing toward the cavity using at leastone removably connectable connection device.

Description

technical field [0001] The present invention belongs to the technical field of tires and relates to a pneumatic tire according to its type, which has an annular cavity and at least one muffler arranged in the cavity and made of an open-celled honeycomb material. Furthermore, the invention relates to a device comprising a rim around which a pneumatic tire is fitted, and at least one muffler made of an open-celled honeycomb material arranged in a cavity between the rim and the pneumatic tire. Background technique [0002] In modern automobiles, driving noise should be as low as possible in the passenger compartment in order to increase the comfort of the passenger. Pneumatic tires without inner tubes have proven to be problematic in this regard, since the annular tire cavity acts as a resonance chamber in which resonant sound waves can be excited by the rotation of the tire and impacts due to uneven road surfaces. Studies have shown that the sound waves generated here propaga...
