GEARBOX Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in step gearshift mechanisms. Proposed gearbox has input shaft 1 and output shaft 2 installed in housing 3, differential transmitting modules and gearshift members. Each transmitting module contains three members, namely inlet one 4-7, outlet one 12-15and intermediate one 8-11. Modules are series-connected so that inlet member of following module is connected with outlet member of preceding module. Input shaft 1 of gearbox is connected with inlet member 4 of first module. Output shaft 2 of gearbox is connected with outlet member 15 of last module. Control members are made as shifters 16-19 connecting intermediate member of each module either with housing 3, or with its outlet member.

EFFECT: simplified design of gearbox owing to increased number of speed at the same number of transmitting modules.
