FIELD: transport.
SUBSTANCE: invention relates to a single-track vehicle gearbox. On a tubular axle secured to the fork of the wheel suspension guide unit there are free tubular input and output shafts of the gearbox. Tooth rims are fixed on them with three-position switching couplings and there are free gears engaged with the gears mounted on the intermediate shaft. Middle one of the three gears of that shaft is engaged with the gear having the tooth rims and freely installed on the axle. Forks are arranged in slots, and switching levers - inside the tubular axle. Wheel hub is fixed to the tubular output shaft. Inside the hub there is a crankcase of the gearbox, which with an intermediate fastening assembly is attached to the fork of the wheel suspension guide unit. Inside that fixing assembly there is a sprocket of the chain transmission fixed on the input tubular shaft.
EFFECT: provided are broader performance and layout characteristics of the vehicle.
