Abstract
A overrunning clutch having a lateral rolling bearing, wherein clamping elements (21) and rolling elements (23) are carried in respective separate cages (22 and 24) between an inner ring (15) and an outer ring (16). The rings are provided with tracks (17, 19 and 20) adapted to the clamping and rolling elements. The breadth of the rings exceeds the length of the clamping elements (21), the cages (22 and 24) adjoin one another, and at least one of the cages (22) is snap-fitted and axially secured by means of radial projections (27) in an annular groove (28) in one of the rings. The clamping element cage (22) has, adjacent the rolling bearing, an axial shoulder (25) and a radial flange part (26). The rolling bearing cage (24) has axially projecting annular beads (29 and 30), one of which merges into a radial guide flange (31), which is guided axially between the annular shoulder (18) and the adjacent flange part (26) of the free-wheel cage (22) and radially by the shoulder (25).
