CLOSED DIFFERENTIAL MECHANISM Russian patent published in 1998 - IPC

FIELD: mechanical engineering; drives with closed differential mechanisms. SUBSTANCE: carrier of closed differential mechanism is made in form of cylinder. Detachable cover with fitted-in axles is arranged at one side of cylinder. Rollers with flanges are mounted on axles. bracket with split ball support is installed through holes made on perimeter. Cylinder has conical bottom at other side with input shaft located in center of bottom at outer side. Epicycle is made in form of cup with inner surfaces. Teeth are cut on one of surfaces. Cardan is connected through connecting link at other side close to end face wall of cup. Axes of epicycle and sun wheel are displaced relative to each other by means of rollers with flanges which roll over epicycle race. Feedback intermediate shaft is cantilever mounted in bearing unit of housing cover and is mechanically coupled with feedback gears. Feedback gear arranged after splined joint is secured in bearing unit of housing cover. EFFECT: increased efficiency owing to making of closed differential mechanism in which ratio of parallel flows is negative. 2 dwg
