摘要： A hybrid-power driving system (HPDS) (110) includes an engine, a motor, and a transmission. The HPDS may include a single clutch and the transmission can provide at least six forward speed ratios and can provide for a reverse speed ratio. The transmission can include three synchronizers and multiple gearwheels that are used in multiple speed ratios. In addition to a pure engine driving mode and a pure motor driving mode, the HPDS can operate using a hybrid-power driving mode (HDM). In the HDM, the HPDS can provide for shifting of gears without power interruption to the half-axles and wheels of a vehicle. In the HDM, the continuous power being output can be achieved by keeping a synchronizer engaged to a gearwheel for two consecutive speed ratios.

摘要： 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.
