VEHICLE TRANSMISSION Russian patent published in 1998 - IPC

FIELD: transport engineering; mechanical transmissions. SUBSTANCE: vehicle transmission has drive to initial transmission including primary shaft with driving reverse gear and two driving gears coming into meshing with driven gears engaging with driven gears for number of forward steps coupled through input clutch with secondary shaft. Input clutch is driven reverse gear. Secondary shaft has more than one final drive driving coming into engagement with output shaft driven gears, thus forming gear pairs with controlled clutches, Driving and driven gears of forward and reverse drives in initial transmission are made in form of spur gear pairs and are controlled by one input clutch made for sliding in both sides along guides of hub rigidly coupled with shaft. Moreover, driving part of one of controlled clutches of final drive is made integral with driven gear disk, and driven part in rigidly coupled through holes ion driven gear disk with rim gear to control the clutch. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
