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, counter-shaft 4 parallel to input and output shafts, gears mounted on shafts, three two-position shifter sleeve A, B, C and three-position shifter sleeve D. member 18 of twin sleeve A is arranged on gear 6 of input shaft 2, other member 19 is mounted on countershaft gear 8 and is coupled with first member 18 by shifter fork 20. Member 21 of twin sleeve B is installed on gear 11 of output shaft 3, and other member 22 is mounted on gear 8 of countershaft and is coupled with first member 21 by shifter fork 23. member 24 is twin sleeve C is installed on gear of third or fourth clusters of output shaft 3 and other member 25 is installed on countershaft gear 10 and is coupled with first member 24 by shifter fork 26. EFFECT: enlarged kinematic capabilities of gearbox, reduced metal usage. 2 dwg
