Abstract
Official abstract text for this publication.
A shaft-hub connection, in particular for a gearbox of a motor vehicle, comprising a shaft, at least one hub which is connected to the shaft, wherein the hub is of tubular design and a shaft end of the shaft engages on a first hub end of the hub, and a closure element is arranged on a second hub end of the hub. A cavity is formed between the closure element and the shaft end of the shaft. The closure element is designed in such a manner that gaseous medium can escape via the closure element in the event of a positive pressure in the cavity.

The invention claimed is: 1. A Shaft-hub connection, in particular for a gearbox of a motor vehicle, comprising a shaft and at least one hub which is connected to the shaft, wherein the hub is of tubular design and a shaft end of the shaft engages on a first hub end of the hub, and a closure element is arranged on a second hub end of the hub, wherein a cavity is formed between the closure element and the shaft end of the shaft, wherein the closure element is designed in such a manner that gaseous medium can escape via the closure element in the event of a positive pressure in the cavity; wherein the closure element is manufactured at least in two parts including a support component and a venting component; wherein the venting component of the closure element has a first portion and a second portion, and wherein the first portion is connected to the second portion via a connecting portion; wherein the first portion of the venting component is of annular design and is arranged in an outer circumferential groove of the support component of the closure element. 2. The shaft-hub connection according to claim 1 , wherein the venting component is movable section by section relative to the support component in the event of positive pressure in the cavity of the hub. 3. The shaft-hub connection according to claim 1 , wherein the venting component of the closure element is manufactured from an elastic material. 4. The shaft-hub connection according to claim 1 , wherein the support component is partially insert-moulded by the venting component. 5. The shaft-hub connection according to claim 1 , wherein the second portion of the venting component is of substantially cup-shaped design which overlaps a central opening in the support component in a closing manner and is movable relative to the support component in the event of positive pressure in the cavity of the hub.
