Abstract: A planetary gear train includes a central wheel, a gear and a carrier, geometrically coupled by a closed eccentric connection that locks the gear. The locking is provided by displacement of the carrier in relation to the gear in a circumferential or tangential direction, when the gear's rotation speed is lower than the carrier's rotation speed. When there is more than one locking gear, the carrier's displacement in relation to the gear can be identical or different. The eccentric connection can be designed as an eccentrically disposed projecting section of outer surface of either the gear or the carrier, conjugated with an opening or slot formed in the carrier or gear, or as an eccentric element having eccentrically disposed projecting sections that may be designed as a single rolling body. The gear train provides for locking (blocking) the gear, as well as for transmitting rotational movement thereby extending its use.

Abstract: The invention relates to differential drives for driving axles and wheels of transport means. The differential includes output shafts, which are kinematically interconnected by at least one differential pinion. The differential pinion is connected to the differential's housing by means of at least one intermediate member, which rotates freely in the housing coaxially to the geometrical axis of the differential pinion, and—conjugated surface zones of the differential pinion and the intermediate member, which zones are offset relative to the geometrical axis of the differential pinion. The conjugated surface zones may have different configurations. The invention makes it possible to simplify the design of a self-locking differential and to significantly increase the range of the blocking effect.
