Abstract

The invention provides a dual-motor dual-clutch dual-speed-ratio electric vehicle power assembly and an electric vehicle, and relates to the field of electric vehicles, the dual-motor dual-clutch dual-speed-ratio electric vehicle power assembly comprises an outer shell, a composite motor and a dual-clutch transmission, the composite motor comprises a first motor and a second motor, the first motor comprises a first rotor, a first stator and a first motor shaft, the first rotor is rotatably arranged in the outer shell, and one end of the first rotor is connected with the first motor shaft. The first motor shaft is hollow, and the end, away from the first rotor, of the first motor shaft extends out of the outer shell and is in running fit with the outer shell. The second motor comprises a second rotor, a second stator and a second motor shaft; the second rotor is rotatably arranged in the second stator, and the second motor shaft is sleeved in the second rotor. The first stator is arranged in the first rotor, and the second stator is arranged in the first stator; or, the first stator is arranged outside the first rotor, and the second stator is arranged in the first rotor.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a dual-motor, dual-clutch, dual-speed-ratio electric vehicle power assembly and the electric vehicle. Background technique [0002] New energy electric vehicles have become the first choice for the development of transportation due to their high efficiency, energy saving, environmental protection and emission reduction. The cruising range of an electric vehicle is related to the efficiency of the powertrain. The powertrain combined with multi-motor and multi-speed ratio transmission enables the electric vehicle to operate in a wide range of high efficiency under complex driving conditions. [0003] The configuration of the powertrain of new energy electric vehicles directly affects the efficiency and cost of electric vehicle operation. Currently, electric vehicles with single or dual motors are configured to drive under complex working conditions, especially at high speeds, with ...
