Abstract
The link joint between a brake cylinder (1) and a brake linkage has a bearing lug (4) attached to a brake cylinder part (2,3). For a pivoting connection between the two, an annular turning surface bearing (14,18) is provided for. The bearing lug (4) is pierced by screw bolts (23) with lateral play, which are screwed to the brake cylinder part (2,3) and the head portions (26) of which are supported by disc springs (28) against the contact point (27) on the bearing lug (4). The rotational center or axis of the turning surface bearing (14,18) is located on the brake cylinder axis (10) in the plane of the contact point (27). With a spherical turning surface bearing (14,18) it is possible to achieve, by an adjusting spring (29), rotatability of the bearing lugs (4) only about a straight line through the ball center (15) of the spherical turning surface bearing (14,18), perpendicular to the brake cylinder axis (10) and the longitudinal axis of the adjusting spring (29).
