Patent ID: 7438163

Claim:
A brake application system for vehicles, particularly rail vehicles, including: an actuator which generates a braking power of the brake application system to move a brake between a brake applied position and a first brake release position of the actuator resulting from a braking power reduction of the brake application system when the brake application system is being acted upon by the braking power; and a combined device for an emergency release of the brake of the brake application system and for an auxiliary release of the brake, wherein the emergency release of the brake being a movement of the brake from the brake applied position of the actuator of the first brake release position of the actuator; the auxiliary release of the brake being a further movement of the brake from the first brake release position of the actuator when the brake is not being acted upon by the braking power; the combined device is electrically actuated by a common first electric drive unit; wherein the combined device for the emergency release and auxiliary release of the brake is integrated in a wear adjuster having a helical gear, the helical gear includes first and second screw connection parts, the first screw connection part including a threaded spindle and the second screw connection part including a nut, which nut can be screwed on the threaded spindle, and at least one of the screw connection parts is electrically actuated for the emergency and auxiliary release of the brake; wherein the second screw connection part of the helical gear for the emergency and auxiliary release of the brake is rotationally actuated by the common first electric drive unit; and wherein the first screw connection part of the helical gear for wear adjustment is rotationally actuated by a second electric drive unit.
