FIELD: transport.SUBSTANCE: invention relates to automatic stepped gearbox comprising set of planetary gears and clutch. Automatic gearbox comprises rotary drum 1 including central gear 2, centrifugal clutch 3, neutral gear toothed ring 4 coupled with said clutch 3, bearing 5 of planetary gear of aforesaid set making a built-in structure, and coupling 6 coupled with rotary drum 1. Note here that engine torque is transmitted via coupling to gearbox rotary drum 1, via the latter to central gear 2 and to neutral gear toothed ring 4 via centrifugal clutch 3 in said rotary drum 1. Coupling 6 arranged in bearings 5 of planetary gear may be coupled with rotary drum 1. Centrifugal clutch 3 coupled with neutral gear toothed ring 4 may be disengaged.EFFECT: simplified design, reduced fuel consumption.1 dwg |
