Abstract
A rail vehicle block brake actuator (1) shall be fixedly mounted, but its brake block holder (4) shall brakingly engage an axially movable wheel (25). For this purpose the brake block holder is laterally movably suspended relative to the brake actuator by means of pivotable hangers (5) each consisting of a stack of leaf springs. These leaf springs (5) are preferably prestressed in a direction for compensating for the bias of the taper of the wheel tread, which it is intended to engage, but are held in a straight condition by means of a flat bar (9).
