Abstract
A bipode joint has a first joint part (1) with a first longitudinal axis (2) and a second joint part (23) with a second longitudinal axis (27). The first joint part (1) has an arm (3) whose diameter is stepped and includes a roller (7') whose face also includes a stepped diameter. The faces are an outer face (9) with a smaller diameter and, on the radial inside, a transmitting face (11) with a larger diameter. A spherical zone is arranged between the two faces. Two running faces (30) are on the second joint part (23) to guide the outer face (9). In the radially inward direction, the running face (30) is followed by a supporting face (32). The supporting face (32) is a partial cylindrical face to support the roller (7') with its spherical zone (10). Further inwardly, towards the second longitudinal axis (27), a supplementary running face (34) follows the support face (32). The supplementary running face serves as a supporting face for the transmitting face (11) of the roller (7'). Rings (35, 36) with hollow spherical zones (39, 40) are provided to limit the plunging distance (54). The rings contact the roller (7') with its spherical zone (10) when adjusted accordingly. It has been possible to achieve a joint with a high torque transmitting capacity and advantageous centering conditions due to the support provided by the spherical zone (10).
