  • Patent number: 5421591
    Abstract: The invention concerns a sealing arrangement for use in steered axles of vehicles employed in agriculture and/or the building trade. The sealing arrangement (24) consists of separate seals (46, 47) which are assembled into a sealing set (48) by way of a sleeve (42). The sleeve (42) is firmly situated in relation to the component (25) to be sealed such as the drive shaft (26) of a steered axle (1). Steering movements departing from the straight ahead drive position produce a displacement of the sealing arrangement (24) from the outer space (21) in a direction toward the inner space (20) of the axle tube (3) of the axle (1).
