VEHICLE DRIVING AXLES AND WHEELS DRIVE POWER DISTRIBUTION MECHANISM Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: power distribution mechanism consists of two plus parallel connected planetary mechanisms arranged coaxially. Central wheel of first planetary mechanism is rigidly connected with housing and with central wheel of second planetary mechanism. Two other central wheels of different planetary mechanisms are interconnected. Gear ratio of each planetary mechanism at torque applied to housing and carriers motionless is selected to provide different sign peripheral forces on rims of central wheels at rigid engagement of wheels, and same sign forces at connection of wheels by kinematic circuit through intermediate gear wheel for reversing. EFFECT: possibility of uniform distribution of torque between driving axles and wheels in two parallel flows irrespective of wheel-to-road adhesion, prevention of wheel slipping, enhanced serviceability of vehicle. 13 cl, 11 dwg
