Wheel suspension

A wheel suspension for a vehicle, in particular an agricultural vehicle, comprises a body-side sleeve (5) and a shaft (1) that is rotatable in the sleeve (5). A pressurized gas passage comprises an annular space (15; 28) bounded by the sleeve (5) and the shaft (1) and channels (7, 8; 16, 29) of the sleeve (5) and the shaft (1) that open into the annular space (15; 28). The annular space (15; 28) is sealed by at least one sealing ring (19) that contacts the sleeve (5) and the shaft (1). An outer surface (20) of the sealing ring (19) is shaped in the relaxed state to be complementary to an inner surface of the sleeve (5) that contacts it in the mounted state, and the diameter of the outer surface (20) is larger in the relaxed state than the diameter of the inner surface of the sleeve (5).
