The present disclosure relates to a sealing arrangement (17) for a vehicle for providing an air transfer chamber between a shaft (7) and a hub (9), surrounding the shaft. One of the shaft and the hub is connected to the body of the vehicle and the other to a wheel of the vehicle. The transfer chamber is ring-shaped and confined between the shaft, the hub, and at least a first (35) and a second (37) ring-shaped seal which are axially separated in the axial direction of the shaft. A sleeve (21) is provided, against which the seals move, and the sleeve has holes (63, 73) providing an outlet for the transfer chamber, which holes are elongated in the circumferential direction of the sleeve. Thereby a stronger sleeve structure can be provided for a given hole area. |
