FINAL DRIVE Russian patent published in 1999 - IPC

FIELD: transport engineering. SUBSTANCE: final drive has housing, meshed driving and driven gears, differential, planetary mechanism and clutches. Driven gear is in meshing with sun gear of planetary mechanism. One of clutches selectively connects differential body with carrier rim or with rim of epicyclic gear wheel. Other clutch, intercoupled with first clutch, connects selectively rim of epicyclic gear wheel with other rim of carrier or with rim secured on housing wall. EFFECT: enlarged kinematic capabilities of transmission owing to increased number of speeds in final drive at limited overall dimensions and mass. 2 dwg
