Abstract:
This invention relates to a cam wedge type one-way clutch, which includes a outer race, an inner race, a cam wedge and a circular spring, wherein some cam wedges are arranged closely between said outer race and inner race. The distance between the outer race and the inner race is smaller than the long diameter of the cam but larger than the short diameter of said cam. Fulcrums are formed on said cam wedges. A annular spring is formed by coupling column type spool spring. Said annular spring is provided between the inner race and the fulcrums of said cam wedge and applies force to said fulcrums to make the cam wedge return to its original location during moving. The part with long diameter of said cam wedge always contacts with said outer race and the inner race. The device of this invention has the advantages as following: it has few components, low cost, high reliability, and simple and compact construction. The cam wedge has high compressive strength.
