FIELD: transport engineering; vehicle transmissions.
SUBSTANCE: proposed gearbox contains input shaft 2 and output shaft 4 arranged in parallel. Four gears 9, 11, 12, 19 are united to form cluster by shaft 3. Gears 16-18 of output shaft 4 are in pair meshing with gears 9-12 of cluster. Gear 19 of cluster engages with gear 22 of output shaft through idler gear or cluster of two reverse gears 21-21. Two shifter sleeves 32, 33 are installed on hubs of output shaft 4. Input shaft 2 is arranged coaxially to four gear cluster shaft. One of gears 6 of input shaft is fixed, and gears 7, 8 are freely fitted. Said three gears are in pair meshing with gears 13-15 freely fitted on output shaft 4. Three two-position twin shifter sleeves A, B, C are installed between four pairs of gears being arranged on gears of parallel shafts. One member is installed on rim of gear of input shaft 2, other member is installed opposite to first member on rim of gear of output shaft 4. Members are intercoupled by three shifter forks 25, 28, 31. Invention provides up to 24 forwards speeds and up to 8 reverse speeds.
EFFECT: enlarged operating capabilities of vehicle.
