<p>COMBINATION FAILSAFE BRAKE AND ONE-WAY CLUTCH A combination fluid power disc brake and one-way clutch unit is offered. An inner shaft is journalled in a stationary housing, and an outer shaft is journalled upon the inner shaft. A one-way clutch between the shafts causes the inner and outer shafts to rotate together as a unit when the inner shaft is rotated in one direction, but permits the inner shaft to rotate independently of the outer shaft when the inner shaft is rotated in the opposite direction. A disc brake assembly operates upon the outer shaft to selectively retard its rotation. The disc brake assembly is of a failsafe design, and permits outer shaft rotation when a positive hydraulic pressure is applied to the unit. If pressure is lost or removed, the brake is activated, and outer shaft rotation is halted.</p> |
