Abstract

The invention provides a dual-motor four-speed-ratio range-extending electric vehicle power assembly and an electric vehicle, the dual-motor four-speed-ratio range-extending electric vehicle power assembly comprises a shell, a composite motor and a first transmission, and the composite motor comprises a first motor and a second motor. Movement is transmitted by cooperating a radial compound motor with a transmission having four gear pairs. And independent four-speed motive power transmission movement is acquired. Certainly, various combinations of resultant force and transmission speed ratios of two motors can be obtained by combining the radial compound motor with different numbers of gear pairs. Through the combined configuration of various motive power and various transmission speed ratios, an effective solution is provided for the power assembly to adapt to complex working conditions and speed per hour, and the electric vehicle can run in a high-efficiency running interval of the motor for a longer time. The power assembly is compact and simple in structure, and multiple functions of a dual-drive motor, a generator, a starting motor and the like are achieved through a dual-motor radial composite structure.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a power assembly of a dual-motor four-speed-ratio extended-range electric vehicle and an 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 the widest range of high efficiency under various complex driving conditions. [0003] The configuration of the new energy electric vehicle powertrain directly affects the efficiency and operating cost of the electric vehicle. At present, the single motor or dual motor configuration of the electric vehicle runs under complex working conditions,...
