Abstract:
A vehicle brake slack adjuster includes a housing coupled to a brake actuator and supporting a driving worm wheel engaging the brake cam shaft and a driving worm screw meshed with the driving worm wheel and transferring a brake actuating force, imparted by the brake actuator to the housing, to the driving worm wheel and cam shaft. The adjuster further includes a wear adjustment mechanism including a reference arm fixed against movement and including a control ring gear, a pinion gear meshed with the control ring gear and configured for rotation about an axis, a clutch ring disposed about the axis and configured for rotation with the pinion gear, a control worm screw disposed about the axis, a wrap spring engaging surfaces of the clutch ring and control worm screw and a control worm wheel meshed with the control worm screw and configured for rotation with the driving worm screw.

Claim (Index 4):
The automatic slack adjuster of  claim 1  wherein the pinion gear defines a first circumferential rib defining the first angular drive face and a third angular drive face at opposite circumferential ends of the first circumferential rib and the clutch ring defines a second circumferential rib defining the second angular drive face and a fourth angular drive face at opposite circumferential ends of the second circumferential rib, the first angular drive face of the first circumferential rib configured to engage the second angular drive face of the second circumferential rib during rotation of the pinion gear in a first rotational direction about the rotational axis and the third angular drive face of the first circumferential rib configured to engage the fourth angular drive face of the second circumferential rib during rotation of the pinion gear in a second rotational direction about the rotational axis, opposite the first rotational direction.
