摘要： A tooth driven over-torque protection mechanism for use in a slack adjuster or as an air disc brake clutch, includes a shaft, toothed gear, a clutch device, a first spring, and a second spring. The toothed gear is disposed on the shaft. The toothed gear has a first pinion teeth set that extends along a first direction and a second teeth set that extends along a second direction. The clutch device that is also disposed on the shaft and includes an upper cam and a lower cam. The first spring biases the toothed gear against the clutch device. The second spring biases the clutch device against the toothed gear. The upper cam has cam teeth that cooperate with the second teeth set of the toothed gear in a torque transmitting manner, such that a torque applied in a clockwise direction to the first pinion teeth is transmitted to the upper cam through the second teeth set, but torque applied in a counterclockwise direction is opposed by the first spring.

摘要： A self-adjusting automatic slack adjuster for reducing slack in the brake of a vehicle includes an adjuster link having a resilient portion. When a brake application force being applied to the slack adjuster exceeds a level that could result in brake application linkage damage as a result of the slack adjuster's slack adjustment mechanism having reached a travel limit, the resilient portion of the adjuster link permits the axial length of the adjuster link to change to accommodate the high brake application force in order to minimize or preclude damage to the brake application linkage.
