The joint is intended to be fitted between two supports, one fixed (30) and the other turning (20). It comprises two frameworks, one attached to each support defining an annular chamber between them. The mobile framework comprises a disc provided with a sealing rib (21) which is mounted in an annular channel (22) in the turning support. The disc carries a magnetic coder element (4) formed from an elastomer charged with magnetic particles. The magnetic coder element covers the outer face of the of the disc and is able to cooperate with a sensor. The second disc (8) has an elastomer covering (10) to form a seal, with an axial lip (11) and a radial lip (11') acting on the two surfaces of the first disc in order to form the seal. |
