Device for maneuvering fast connection tangential button operated of splined profile clutches, especially on end forks of agriculture cardanic shafts

摘要

Device for maneuvering a fast connection tangential button operated in the tranmissions having splined profile clutches or joints, comprising an annular member encircling the body of the joint and having an internal profile making up a thrust surface able to act on the button as a consequence of an angular displacement of the annular member around the joint body; the reaction spring acting on the button angularly urges said annular member in a direction opposite to that causing the release action upon the button.
