Abstract
The present invention includes new types of one-way clutches that can gradually and smoothly engage the load. The novel design of the present invention permits a multiplicity of several embodiments which includes a hydraulic one-way clutch (H.O.W.C.) and a damped one-way clutch (D.O.W.C.). The H.O.W.C. has a general configuration similar to a fluid rotary actuator. It has two or more collapsible vanes which are made to rotate about a pivot between a radial driving position and a collapsed position, in which the collapsible vanes are either partly or fully pushed away from the driving position. A body of fluid is filled between a rotor's vane and the two collapsible vanes to provide the desired damping effect. The D.O.W.C. utilizes an additional ring which is an actuating ring and is placed on an external ring with a bearing between the actuating ring and the external ring so that it can rotate around the external ring. The external ring and the actuating ring are linked together through radial extensions and a fluid cylinder between them. Each engagement cycle begins with the external ring being pushed by the actuating ring. To start the transfer of the full torque, the fluid has to be first compressed which provides for the gradual build-up in the torque.
