Pneumatic vehicle tire
The invention is directed to a pneumatic vehicle tire with a foam sound absorber therewithin and adhesively attached to the inner side opposite from the tread. The sound absorber has a contact side, by which it adheres to a previously applied, self-sealing sealant. The sealant has a tackiness required for the adhesive attachment of the sound absorber. The contact side of the sound absorber has a contact area on the sealant of between 5% and 50% with respect to the total area of the contact side.
1. A pneumatic vehicle tire comprising:
a tread;
an inner side lying opposite said tread;
a sound absorber having a contact side and being adheredly applied to said inner side;
said inner side and said contact side conjointly defining an interface;
a self-sealing sealant applied in advance at said interface so as to permit said sound absorber to adhere with said contact side to said sealant;
said sealant having a tackiness required for adhesively attaching said sound absorber at least directly after being applied at said interface; and,
said contact side of said sound absorber having a contact area lying in a range of 5% to 50% referred to the total area of said contact side;
wherein said sound absorber is a convoluted foam with said contact side thereof being formed with nubs having respective nub tips lying upon said sealant; and,
wherein only the nub tips lie on the sealant.
2. The pneumatic vehicle tire of claim 1 , wherein said contact side of said sound absorber has a contact area on said sealant lying in a range between 10% and 40% with reference to the total area of said contact side.
3. The pneumatic vehicle tire of claim 1 , wherein said contact side of said sound absorber has a contact area on said sealant lying in a range between 20% and 30% with reference to the total area of said contact side.
4. The pneumatic vehicle tire of claim 1 , said convoluted foam having a thickness lying in a range of 10 mm to 50 mm.
5. The pneumatic vehicle tire of claim 1 , said convoluted foam having a thickness lying in a range of 20 mm to 30 mm.
6. The pneumatic vehicle tire of claim 1 , wherein said sealant is a viscous mixture based on a butyl rubber, a polybutene or on the basis of silicone.
7. The pneumatic vehicle tire of claim 1 , wherein said sealant has a layer thickness lying in a range of 2 mm and 5 mm.
8. The pneumatic vehicle tire of claim 1 , wherein said sealant has a layer thickness lying in a range of 2 mm and 3.5 mm.
9. The pneumatic vehicle tire of claim 1 , wherein said tire defines a zenith; and, said sound absorber is arranged eccentrically relative to said zenith of said tire.
10. The pneumatic vehicle tire of claim 1 , wherein said sound absorber has a width corresponding to approximately the width of said sealant.
