Abstract (en)
[origin: EP0381956A2] The shoe brake unit has two brake blocks (4 and 5) per vehicle wheel (1), of which one brake block (4) can be actuated directly and of which the other brake block (5) lying opposite can be actuated indirectly by a shoe braking unit (6) via a drawbar 14. A two-armed lever (20) which is mounted indirectly or directly on a fixed bearing (19) of the axial bearing (3) is provided, the one end of said lever being coupled to the one brake block (4) and its other end being coupled to the other brake block (5) indirectly via bars (21, 24) or directly. By means of the two-armed lever (20) and its coupling to the brake blocks (4 and 5), it is ensured that, in the release state, the latter are constantly lifted off from the vehicle wheel (1) through identical degrees of release travel; these degrees of release travel are also maintained in the case of longitudinal displacements of the vehicle wheel (1) such as occur with steering axles. <IMAGE>
