FIELD: mechanical engineering; agricultural engineering; machine-tool building. ^ SUBSTANCE: invention relates to step speed change mechanisms. Proposed gearbox has input shaft 1 and output shaft 2 installed in housing 3, transmitting modules and gearshift controlled members. Each module 1-IV is provided with through input shaft and output shaft coaxial to input shaft. Gearshift controlled members are made as shifters, and they connect input of following module either with through input shaft or with output shaft of preceding module. Driven shaft of gearbox is connected by shifter either with through input shaft or with output shaft of last module. ^ EFFECT: increased number of speeds at one and the same number of transmitting modules and control members, reduced overall dimensions of gearbox. ^ 12 cl, 8 dwg |
