FINAL DRIVE Russian patent published in 1999 - IPC

FIELD: transport engineering. SUBSTANCE: final drive has two driving gears and two driven gears brought into meshing, differential, planetary mechanism and clutches. One of driven gears is connected with planetary mechanism carrier. Epicyclic wheel of planetary mechanism is secured on differential case. Clutch engages sun gear of planetary mechanism either with second driven gear or with tubular support of differential case. EFFECT: enlarged kinematic properties of final drive owing to increase in number of speeds and maximum gear ratio at limited dimensions and metal usage.
