Bicycle tyre

Abstract

The invention relates to a bicycle tire with high riding comfort. A damping rubber insert (3) made from a highly elastic rubber is arranged between the tire tread (2) and the tire carcass. Said damping rubber insert (3) has a material thickness of between 0.2 and 2 mm, and the carcass insert ends (10) extend to a maximum of the lateral edge areas of the tire tread (2).

Claims

1. A bicycle tire consisting essentially of: a running strip; a polyester polyacrylate cut-resistant fibrous layer disposed inwardly adjacent the running strip; a damping rubber inlay comprised of a highly elastic rubber disposed inwardly adjacent the polyester polyacrylate cut-resistant fibrous layer; a tire carcass disposed inwardly adjacent the damping rubber inlay; tire side walls; and, a tire bead comprising a core; wherein the tire carcass comprises at least one carcass inlay, wherein the at least one carcass inlay is folded back over the core and terminates in the tire side walls, wherein the damping rubber inlay comprised of a highly elastic rubber is laid upon the at least one carcass inlay, and wherein ends of the at least one carcass inlay at maximum reach up to lateral peripheral regions of the running strip.

2. The bicycle tire as claimed in claim 1, wherein the tire carcass comprises two carcass inlays disposed on top of one another, wherein the tire side walls are reinforced, and wherein rolling resistance is reduced by way of carcass construction.

3. The bicycle tire as claimed in claim 1, wherein the tire carcass comprises two carcass inlays disposed on top of one another, wherein the two carcass inlay ends terminate below the lateral peripheral regions of the running strip.

4. The bicycle tire as claimed in claim 1, wherein the tire carcass comprises two carcass inlays disposed on top of one another, wherein the two carcass inlays each comprise individual strength members running in parallel, wherein the strength members are disposed at an intermediate angle of 40 to 60 degrees, and wherein the strength members have mutually opposite inclination angles.

5. The bicycle tire as claimed in claim 1, wherein the damping rubber inlay has a material thickness between 0.3 and 1 mm.

6. The bicycle tire as claimed in claim 1, wherein the bicycle tire is a racing bicycle tire operated at a minimum tire pressure of approximately 6.5 bar.

7. The bicycle tire as claimed in claim 1, wherein the polyester polyacrylate cut-resistant fibrous layer is formed from a cut-resistant woven fabric.

Description

(1) The invention is to be explained in greater detail using one exemplary embodiment. The drawings show:

(2) FIG. 1: a bicycle tire in the cross section.

(3) FIG. 1 shows the relevant tire components of the bicycle tire in a cross-sectional view. The racing bicycle tire illustrated has two carcass inlays 6 and 7, lying on top of one another. The carcass inlay ends 10 are folded back over the core 8 on both sides, reaching so as to be shortly below the lateral regions of the running strip 2. The carcass inlay ends 10 cover the side wall of the racing bicycle tire in a substantially complete manner. Thus, four layers of the woven carcass fabric are disposed on top of one another in the region of the side wall, on account of which the side wall overall has a high rigidity. The damping rubber layer 3 which preferably has a material thickness between 0.3 and 1 mm is disposed below the running strip 2. The rubber inlay 3 covers the lower side of the running strip 2 in a substantially complete manner. Moreover, a cut-resistant fibrous layer 4 which in the FIGURE is illustrated as a dashed line is disposed below the running strip 2. The cut-resistant fibrous layer guarantees optimum puncture protection. In the case of the new tire construction the carcass inlay ends 10 do not reach below the running strip, on account of which the ride comfort of the racing bicycle tire is significantly improved. The damping rubber inlay 3 likewise contributes toward increasing the ride comfort.
