Abstract
A wedge brake arrangement for drum brakes on heavy road vehicles includes a brake cylinder push rod (29), plungers (26) axially movable perpendicularly to the push rod, and force transmitting rollers (32) between parallel wedge surfaces at the end of the push rod and on the respective plunger. In order to obtain full control over the reaction forces from the plungers (26) at brake operation the push rod (29) is guided by the housing (25) of the arrangement in the plane of the plungers by means of guide rollers (35) between plane surfaces at the end of the push rod (29) and in the housing (25), respectively, the surfaces being parallel with each other and with the axis of the push rod.
