  • Patent number: 5343991
    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).

  • Patent number: 5267807
    Abstract: The connection for releasably joining two drum components of a hydraulically-actuated double friction disc clutch includes first and second drum components having circular cylindrical surface directed substantially axially, one overlapping the other. The inner component is formed with a catch groove or two catch recesses and the outer drum component includes catch projections, offset mutually 180.degree. and adapted to become locked within the catch groove. The outer drum includes tabs at an axial end adapted to fit within recesses formed on the periphery of the inner drum between catch projections. The drums are driveably connected by applying oppositely directed axial force sufficient to snap the catch projections into the catch groove. The drums are disassembled by elastically deforming the outer drum until the catch projections clear the catch groove and then applying an axial force that separates the drums.
