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 figure 1 , Which schematically shows a partially cutaway perspective view of a first embodiment of a tubeless pneumatic tire for automobile wheels according to the present invention. The pneumatic tire generally indicated by the reference numeral 1 includes a tread portion 2 radially outside for the pneumatic tire 1 to roll on the road, and two sidewall sections 3 And the two bead segments 4 radially inward, when the pneumatic tire is installed on the rim and then inflated, the bead segments 4 closely abut on the rim.

[0025] Pneumatic tire 1 A generally circular or toroidal inner cavity 5 is surrounded by its different sections 2-4, 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 uneven roads, it may be excited to form resonant sound waves in the inner cavity 5, which propagate in the circumferential and radial directions.

[0026] In order to reduce th...

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 least one removably connectable connection device.

Description

Technical field [0001] The present invention belongs to the field of tire technology. According to its type, it relates to a pneumatic tire. It has a circular cavity and at least one muffler made of an open-cell honeycomb material arranged in the cavity. In addition, the present invention also relates to a device, which includes a rim covered with a pneumatic tire, and at least one muffler made of an open-cell honeycomb material arranged in the cavity between the rim and the pneumatic tire. Background technique [0002] In modern cars, in order to improve ride comfort, the smallest possible driving noise should be generated in the cabin. In this regard, it has been proved that there is a problem with pneumatic tires without inner tubes, because the toroidal tire cavity functions as a resonance cavity, and the resonant sound waves can be excited in the resonance cavity through tire rotation and impact based on uneven roads. Research has shown that the sound waves generated here pr...
