TWO-WAY OR DOG CLUTCH AND SELECTABLE ONE-WAY CLUTCH USING TILTED OR ANGLED SPRAGS

摘要

This invention describes two types of mechanical clutches; a selectable one-way clutch and a two-way or dog clutch. Both clutches are constructed with sprags mounted on an axis that is tilted with respect to the axis of the shafts being connected by the clutches. Both engagement faces of the clutch are conical and parallel such that the clutches can be disengaged by withdrawing one of the clutch plates along the line of the shafts being connected. Sprags produce a one-way clutch. In the dog clutch, alternate sprags are mounted opposite to its neighbor, so the clutch is prevented from slipping in either direction.
