GEARBOX Russian patent published in 2001 - IPC

FIELD: transport engineering. SUBSTANCE: proposed gearbox has housing 1, coaxially mounted input shaft 2 and output shaft 3, and countershaft 4 installed in parallel to input and output shafts. Input shaft gear 5 is fixed on shaft. Three gears 6, 7, 11 of countershaft are in meshing with input shaft gear 5 and output shaft gears 8, 9, respectively. Countershaft gear 12 engages through cluster of reverse gears 13, 14 with output shaft gear 10. Shifter sleeve is arranged on output shaft between reverse and low gears. Twin sleeve is mounted on gears 8, 9 of output shaft 3 and gears 7, 11 of countershaft 4. Second twin sleeve can be arranged between gears 5, 8 of input shaft 2 and output shaft 3 or on gear 8 of output shaft and gear 7 of countershaft. EFFECT: reduced metal usage in manufacture of gearbox. 2 dwg
