Abstract

A rolling boot that has improved stability especially at increased rotational speeds comprises a first fastening region, a second fastening region, a transition region adjacent to the first fastening region, as well as a diaphragm region adjoining the transition region, and at least on peripheral reinforcement fin is arranged on an external side of the transition region.

First claim

The invention claimed is:

1. An apparatus, comprising:
a rotating boot that includes a first fastening region, a second fastening region, a transition region adjacent to the first fastening region, and an adjoining membrane region comprising a first membrane part and a second membrane part which are connected to each other via a rounded part;
wherein at least one circumferential reinforcement fin is located on the outer surface of the transition region;
wherein a plurality of supporting fins are located between the reinforcement fin and the first membrane part;
wherein the transition region comprises the reinforcement fin and a wall portion on which the reinforcement fin is arranged; and
wherein the wall portion directly adjoins the first membrane part.

2. The apparatus of claim 1 , wherein the reinforcement fin is substantially perpendicular to an inner surface of the wall portion.

3. The apparatus of claim 1 , wherein the reinforcement fin is closer to the first membrane part than to the first fastening region.

4. The apparatus of claim 1 , wherein an angle α in a range of approximately 0° to approximately 25° is formed between a lower surface of the reinforcement fin and an upper surface of the first membrane part.

5. The apparatus of claim 1 , wherein the supporting fins and the at least one reinforcement fin are substantially perpendicular to one another.

6. The apparatus of claim 1 , wherein a plurality of radial fins are located above the reinforcement fin.

7. The apparatus of claim 6 , wherein the supporting fins and the radial fins are substantially flush with one another.

8. The apparatus of claim 6 , wherein more supporting fins than radial fins are provided.

9. The apparatus of claim 1 , further comprising a slip joint that includes the rotating boot.

10. The apparatus of claim 1 , further comprising a shaft that includes the rotating boot.

11. The apparatus of claim 1 , further comprising the rotating boot, at least one slip joint, and one shaft.

12. The apparatus of claim 1 , wherein the reinforcement fin extends axially from the wall portion.

13. The apparatus of claim 1 , wherein the respective supporting fins extend from the reinforcement fin to the first membrane part.
