Abstract

A clutch employing a split ring to provide a constant limited slip capability is disclosed in Figs. 1 and 2. The clutch is comprised of a shaft member 10 having mounted thereon a retaining member 12. Retaining member 12 is in frictional engagement with a drive element or disk 14 having gear teeth 16 or other drive surfaces formed in the periphery thereof. Subject to the surface frictional forces between retaining member 12 and drive disc 14, drive disc 14 is free to rotate on shaft 10. Fixedly mounted to shaft 10 is flange element 18. Flange element 18 and drive element 14 both have complimenting surfaces forming a V-trough therebetween.

Split Ring Torque Limited Slip Clutch

A clutch employing a split ring to provide a constant limited slip capability is disclosed in Figs. 1 and 2. The clutch is comprised of a shaft member 10 having mounted thereon a retaining member 12. Retaining member 12 is in frictional engagement with a drive element or disk 14 having gear teeth 16 or other drive surfaces formed in the periphery thereof. Subject to the surface frictional forces between retaining member 12 and drive disc 14, drive disc 14 is free to rotate on shaft 10. Fixedly mounted to shaft 10 is flange element 18. Flange element 18 and drive element 14 both have complimenting surfaces forming a V-trough therebetween.

Engaged in the V-trough is a split ring 20. The drive force exerted through 16 is transmitted through the frictional forces exerted thereon by split ring 20 and a complimenting opposite frictional force exerted on driven flange element 18. Inasmuch as flange 18 is fixedly attached to shaft 10, shaft 10 is then driven in response to the driving force exerted on drive disc 14, up to the frictional limits established by split ring 20 and the cooperating surfaces of drive disc 14 and flange 18.

Fig. 2 illustrates a second embodiment, where a drive element 16 acts through split rings 20 to retaining collar 13 and driven member 18. Retaining disc 12 may be fixedly attached to retaining collar 13.

To increase the torque limit of the slip clutch, the driven disc 18 may be moved leftward in Figs. 1 an...
