Abstract

See full text

A dual-motor power system or a dual-motor hybrid power system for a vehicle comprises a first motor, a second motor, an intermediate shaft, a first gear set disposed between a first driving shaft, and an intermediate shaft. The first driving shaft couples with the intermediate shaft via the first gear set, a second gear set disposed between the second driving shaft and the intermediate shaft, and a single synchronizer disposed around the second driving shaft. The synchronizer can be switched between a neutral position, a first-speed-ratio position, and a second-speed-ratio position. In the neutral position, the second driving shaft is decoupled from the first and second gear sets. In the first-speed-ratio position, the synchronizer couples the second driving shaft with the intermediate shaft via the first gear set. In the second-speed-ratio position, the synchronizer couples the second driving shaft with the intermediate shaft via the second gear set.
