The integrated system has advantages of compact structure, high power density and high system efficiency.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a dual-motor nested electric stepless variable speed electromechanical integration system. Background technique [0002] With the rapid development of the automobile industry, "energy saving" and "emission reduction" have become the main theme of the development of the automobile industry. As an intermediate product of the transition from traditional power to new energy power, the hybrid power system has outstanding energy-saving effects, and at the same time takes into account the convenience of use and driver habits. It has become an essential technical solution for the current development of automobiles. According to its structural principles, hybrid power is divided into three types: series hybrid power, parallel hybrid power, and hybrid hybrid power. It has the characteristics of high fuel economy, flexible control, and strong power, and has been valued by re...
