Abstract
Abstract A railway vehicle brake block holder (11) for a brake unit (1)wian brake block hangers (9) pivotally attached to a fixed part (8) of the unit and to the brake block holder. A force transmitting arrangement between the only axially movable brake unit push rod (3) and the brake block holder includes a cradle (14) in the brake block holder and a corresponding force transmitting member (15) therein acted on by the push rod. In order to ensure that the force transmitting member (15) can only move under relatively high forces at least one, preferably Ω-shaped, prestressed spring (16) in a suitable recess (17) in said member biases the latter against the cradle (14).
