SEVEN-SPEED TRANSMISSION OF VEHICLE Russian patent published in 2018 - IPC F16H3/02 F16H3/91 F16H37/04 

FIELD: machine building.

SUBSTANCE: invention relates to transmission. Transmission contains two primary shafts (1) and (2) of different diameters, which are driven by two clutches (3) and (4), intermediate shaft (5) and secondary shaft (6). On shaft (1) of a larger diameter there are freely mounted two gears (7) and (8) that connected with it by gear coupling (9), meshed with gear wheels (10) and (11) that fixed to shaft (5), and fixed gear wheel (12) meshed with gear wheel (13) loosely located on shaft (5) and connected to it gear coupling (14). On shaft (2) of smaller diameter, there is fixed gear wheel (15), that meshed with gear wheel (16), freely disposed on shaft (5) and connected with it by gear coupling (14). On shaft (5) there are fixed gear wheel (17) meshed to gear wheel (18), which is loosely located on shaft (2) and connected to it by gear coupling (19), gear wheel (20) meshed with gear wheel (21) loosely disposed on shaft (6) and connected with it by gear coupling (22). On shaft (5) there is also fixed gear wheel (23), which has a kinematic connection through intermediate pinion (24) with gear wheel (25), freely located on shaft (6) and connected to it by gear coupling (22).

EFFECT: reduction of axial dimensions of the gearbox and increase in the number of reverse gears is achieved.
