FIELD: transport.
SUBSTANCE: proposed gearbox comprises housing 25, driven and driven shafts interconnected with different gear ratio, shaft 1 to control gear shifting, and two guide elements 10, 5. Said shaft 1 is mounted to axially turn and displace between positions corresponding to different gear ratios along preset paths, while said guide elements 10, 5 interact to set said paths. Guide element 10 displaces together with control shaft 11 while second element 5 is arranged on first flange 26 jointed with gearbox housing 25. First flange 26 is split-jointed with gearbox housing 25 and connected with control shaft 1 to make an integral unit therewith. Guide elements 10, 5 are pressed together by adjustable contraction force spring 30.
EFFECT: simplified design.
