Abstract

814,786. Freewheel clutches. MAURER, A. May 3, 1957 [June 1, 1956], No. 14190/57. Class 80 (2). In a freewheel coupling having tilting wedging pieces urged into contact with the outer race by a tubular spring, the contact surfaces 7, 9 of each wedging piece with adjacent wedging pieces, and the contact surface 5 with the outer race are formed as cylindrical surfaces having a common centre of curvature 11 and the same radius 6. The radius 13 of the surface contacting the inner race is greater than the radius of the other surfaces. The centre of gravity of the wedging piece lies on the same line 11 as the common radii of curvature.
