TWO-GEAR VARIABLE-SPEED BRIDGE DRIVING SYSTEM WITHOUT DRIVING FORCE INTERRUPTION

WIPO Patent Application WO/2021/073184

A1

A two-gear variable-speed bridge driving system without driving force interruption, comprising a duplex planetary gear set (PG), a sun gear of the duplex planetary gear set (PG) being meshed with a second planetary gear (G2), a first planetary gear (G1) being meshed with a first gear ring (R1), and the second planetary gear (G2) being meshed with a second gear ring (R2); an outer hub of a first clutch (C1) is fixed, and an inner hub of the first clutch (C1) cannot be rotatingly connected to the first gear ring (R1); an outer hub of a second clutch (C2) is fixed, and an inner hub of the second clutch (C2) cannot be rotatingly connected to the second gear ring (R2); and the output torque of a motor (E) is transmitted to the sun gear, and the output torque of a planet carrier is transmitted to a differential (D). The gear shifting operation of the driving system is achieved by two independent clutches (C1, C2); moreover, the system has a simple structure, and driving force may not be interrupted during gear shifting.
