Abstract
The invention concerns a gearbox, comprising a hollow shaft (21) perforated with radial orifices (214, 215, 216); idling gears (44, 45, 46) mounted rotating on the hollow shaft (21), each of which has internal splines; a cottering rod (5) mounted mobile in translation in the hollow shaft (21); and rows of balls (64 to 66) arranged opposite the idling gears; the cottering rod having a radial protuberance (21) designed to be engaged, depending on the axial position of the cottering rod, the balls of either of the rows in the splines of the corresponding gear. The inventive gearbox comprises a cage (7) fixed in rotation relative to the hollow shaft (21) and arranged between said shaft and the idling gears, said cage (7) consisting of segments whereof only two can be, at any one time, spaced apart from each other to enable the balls of the corresponding row to be engaged in the splines of the corresponding gear.
