GEAR BOX FOR VEHICLE Russian patent published in 1995 - IPC

FIELD: transport mechanical engineering. SUBSTANCE: gear box has input shaft 1, intermediate shaft 2, output shaft 3, controllable clutches 5-8, controllable brakes 9,10, gear wheels 11- 16, first planet set having central wheel with outer teeth 17, carrier 18 with satellites 19, and central wheel with inner teeth 20, and second planet set having central wheel with outer teeth 21, carrier 22 with satellites 23, and central wheel with inner teeth 24. Inlet shaft 1 is coupled with intermediate shaft 2 through clutch 5 and engaging gear wheels 11,12 as well as through clutch 8 and engaging gear wheels 13,14. In addition, shaft 1 is coupled with central wheel 20 through clutch 6 and engaging gear wheels 15,16. Clutch 8 connects central wheels 17,20 of the first set. Brakes 9,10 are coupled with central wheels 20,24. Central wheels 17,21 are interconnected and connected with shaft 2. Carrier 18 is coupled with central wheel 24. Carrier 22 is connected with output shaft 3. There are two control members for each transmission ratio. There are nine transmission ratios for the forward motion and one transmission ratio for the back motion. The load is transmitted through the gear wheels and planet set in one or several fluxes. EFFECT: enhanced reliability. 2 dwg
