Abstract

The invention provides a power transmission device, a power assembly and a vehicle, and relates to the field of vehicle transmissions. The power transmission device includes a first input shaft, a second input shaft, a third input shaft, an output shaft, a transmission mechanism, and a control mechanism. The transmission mechanism is connected between the first input shaft and the second input shaft, between the second input shaft and the output shaft and between the third input shaft and the output shaft. The control mechanism is used for controlling power transmission paths of the transmission mechanism; the power transmission paths comprises the paths through which power input by the second input shaft is transmitted to the first input shaft and the output shaft at the same time, powerinput by the third input shaft is transmitted to the output shaft, power input by the second input shaft is transmitted to the output shaft, power input by the first input shaft and the second input shaft is transmitted to the output shaft at the same time, and power input by the first input shaft, the second input shaft and the third input shaft is transmitted to the output shaft at the same time. By means of the power transmission device, the efficiency of a vehicle power system can be optimal.

Description

technical field [0001] The invention relates to the field of vehicle transmissions, in particular to a power transmission device, a power assembly and a vehicle. Background technique [0002] A hybrid electric vehicle is a vehicle that uses multiple sources of energy, usually a conventional engine using liquid fuel and an electric motor using electrical energy to propel the vehicle. Hybrid vehicles can operate in a variety of drive modes, but have limited battery capacity and rely primarily on engine combustion for power. Most of the hybrid structures at this stage adopt the hybrid mode, that is, the electric motor is placed on the input shaft of the transmission. [0003] The hybrid transmission system in the prior art is mainly based on the current mature dual-clutch transmission technology and motor control technology. By changing gears, the drive motor and engine can work in a high-efficiency range for a relatively long period of time, improving work efficiency. , whic...
