FIELD: transport.
SUBSTANCE: invention relates to gearshift actuators in planetary transmissions in wheel hub. Pair of sun gears has fixing projections (23b) for engagement with axle (10) via pawls (12b, 13b). Sun gears disengagement from axle (10) is provided by pawl control ring. This ring has casing (16) with hold-down elements (18) in the form of rollers. Splined grooves (27b) are created on inner circumference of carrier (20) or on separate body (29) capable to slip relative to carrier (20). Carrier (20) rotation provides gradual pushing out of hold-down elements (18) from deep section of splined grooves (27b) with corresponding holding down pawls (12b) and their disengagement from fixing projections (23b) of one of sun gears.
EFFECT: solution is intended to use impelling force of pedal and/or motor as auxiliary force to facilitate shifting.
