Double-disc type motor electric stepless speed change mechanical-electrical integration system

Abstract

The invention relates to a double-disc type motor electric stepless speed change mechanical-electrical integration system. The system comprises a shell, a planet wheel, a sun wheel, an input shaft, aplanet carrier, a gear ring carrier, a gear ring, an output shaft, a hollow shaft, an ISG motor stator, an ISG motor stator, an ISG motor rotor, a main drive motor stator, a main drive motor rotor anda main drive motor stator; the ISG motor stator and the ISG motor rotor form an ISG disc type motor; the main drive motor stator and the main drive motor rotor form a main drive motor with a double-stator structure; the output shaft penetrates through the hollow shaft; supporting bearings are arranged between the front end and the rear end of the hollow shaft and the output shaft; the sun wheel,the planet wheel and the gear ring form a planet row; the ISG motor stator and the main drive motor stator are connected together and are connected with the hollow shaft through the support bearings;an ISG motor stator side shell is connected with the hollow shaft through the supporting bearing; a main drive motor stator side shell is connected with the output shaft through the supporting bearing. The system of the invention has the advantages of compact structure, high power density, high system efficiency and outstanding NVH characteristics.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an electromechanical integration system of double-disc motor electric stepless speed change. 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. [0003] 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 v...
