FIELD: machine building.SUBSTANCE: mechanism comprises two overrunning clutches, an input shaft and a fixed supporting axis in relation to which rotation directions of all parts are indicated, it is provided with one working direction of a wheel rotation called "forward" and there is no possibility of rotating the wheel as a driving one in the opposite direction called "backwards". The said mechanism comprises a planetary gear set connected to the overrunning clutches so that at the forward rotation of the input shaft the moment is transferred directly from the input shaft to the hub and the planetary gear set is unloaded which provides for the transmission of 1:1. When the input shaft rotates backwards, the moment is transferred to the hub through the planetary gear set which reduces the transmission ratio and inverts the direction thus rotating the wheel hub forwards at the reduced gear.EFFECT: simplified design, lower weight.3 dwg |
