ABSTRACT:
A slack adjuster for use in combination with a pneumatic brake actuator cylinder wherein the slack adjuster includes a friction clutch which prevents rotation of the screw for first relative position of the piston and screw while allowing rotation of the screw for excess force on the ram pulling the screw to a relative position beyond the first relative position and opposite the relative position for normal slack adjustment in response to air actuation of the piston. A second clutch, which is a standard toothed clutch, prevents rotation of the screw for second relative position of the piston and the screw. The screw rotates between the first and second relative positions when the two clutches are unlocked to produce slack adjustment. The pulling force on the slack adjuster is produced by a hand brake on the output of the slack adjuster and independent of the piston.
