    The invention relates to mechanical engineering, in particular to gear boxes of vehicles. The gearbox is known for containing a housing with holes for podglips. front wall, front cover with bearing holes for coaxial holes in the front wall, driving, driven and intermediate shafts, gear wheels mounted on shafts with the possibility of their separation by means of hydraulically driven couplings, hydraulic distributor providing switching of the corresponding G12 couplings. However, the well-known transmission box lacks reliability and is greater than one; The purpose of the invention is to increase reliability and reduce size. This goal is achieved by having a gearbox containing an opening with holes for bearings in the end wall, an end cover with holes for bearings coaxial with holes in the end wall, driving, driven and intermediate shaft gears mounted on the la their disconnection by means of hydraulically driven couplings, hydraulic distributor providing switching of the corresponding couplings .. - is provided with a vertical wall located inside the case between its end wall and the roof ki and once cases guide housing to the primary settler compartment and the liquid associated conduits together with hydraulic pump. and an additional cover is installed on the side of the end cover, forming an additional compartment and in it a console on the shafts houses at least two gears. A recess in which the hydraulic distributor is installed is made on the housing from the end wall. An end hole is provided in the end cap for supplying fluid to the additional compartment. FIG. 1 shows a gearbox, a common fork; in fig. 2 - parts of the gearbox, general isometric view; in fig. 3 shows section A-A in FIG. 2. The gearbox consists of a housing 1 with holes in the end wall for bearings, an end cover 2 with holes for bearings, a drive shaft 3 connected to a torque converter 4. Gears 5 and 6 are freely mounted on the drive shaft 3, connected with a drive shaft 3 with the help of a friction clutch 7 with hydraulic control. A gear wheel 8 of an intermediate shaft 9 is connected to the gear wheel 6 of the drive shaft, on which, in addition, gears 10-12 are freely mounted and the friction clutches 13 and 14 which connect them to the shaft 9 are rigidly mounted on the driven shaft 15 - 18, which are in engagement with the respective gear wheels 12 - 10 of the intermediate shaft 9. The friction clutches 7, 13, 14. are hydraulically controlled hydraulically. A dispenser 19. In case 1, there is a vertical wall 20, which divides the case 1 into a main compartment 21 and a sump 22. 1 The fluid (lubricant) from the compartment 21 is pumped to the sump 22 by means of a hydraulic pump 23 through the pipeline 24.. . Outside, a supplementary cover 25 is fastened to the end crack 2, inside which an additional compartment 26 is formed to accommodate cantilever gears 12, 16 and the friction clutch 16 in it. The gearbox operates as follows. . From the torque converter 4, moment is transmitted to the drive shaft 3 of the box. Further, when the respective friction clutches 7, 13,14 are turned on, the torque is transmitted through the respective gears to the intermediate shaft 9, from which also the torque is transmitted to the driven shaft 15 through the corresponding gears; In the proposed gearbox, due to the separation of the vertical wall 20 of the housing 1 into the main compartment 21 and the oil sump 22 with forced pumping of the latter using a pump-23, as well as by placing the hydraulic distributor 19 9 recess of the housing 1 in close proximity to the switchable couplings and the cantilever arrangement of the part gears (12, 16) with clutch 14 in the additional compartment 26 managed to significantly reduce the dimensions of the gearbox, reduce its weight and improve reliability.
