Abstract

A cage for an overrunning clutch with a metallic outer race accommodating concentrically a metallic inner element and having in a cage arranged between the outer race and the inner element camming elements retained under the action of springs in camming contact with the surfaces of the outer race, on the one hand, and of the inner element, on the other hand, the cage being made of injection moldable or castable polymeric material and having pockets for the camming elements defined by crossbars and at least one end ring connected therewith, at least one circumferential surface of the cage cooperating in the form of a sliding bearing with a cylindrical surface of the adjacent structural part (outer race and/or inner element), characterized in that the cage (1,15,22,30,39) is provided at least in the area of the end ring (4,18,23,33,45) with an annular metallic reinforcement shield (13,19,20,26,27,34,35,47) connected to the cage (1,15,22,30,39) in a form-fitting manner especially through injection-molding around the shield and whose temperature expansion coefficient corresponds essentially to that of the outer race (5,40) and the inner element (9,41).
