Abstract

The invention discloses a dual-motor stepless variable speed vehicle power system with high working efficiency. The dual-motor stepless variable speed vehicle power system with the high working efficiency comprises a high-speed driving motor which comprises a high-speed motor shaft, low-speed driving motors which comprise low-speed motor rotors and an output shaft, and the right end of the high-speed motor shaft of the high-speed driving motor is fixedly connected to a first sun wheel of a first planetary row. The dual-motor stepless variable speed vehicle power system with the high working efficiency is characterized by further comprising an outer ring and a second planetary row, wherein a second sun wheel of the second planetary row is located in a second planetary carrier, a second planetary wheel of the second planetary row is rotatably installed on the second planetary carrier, a second gear ring of the second planetary row is located outside the second planetary carrier, a first planetary carrier of the first planetary row is fixedly connected to the second sun wheel of the second planetary row, the left end of the outer ring is fixedly connected to a first gear ring of the first planetary row, the right end of the outer ring is fixedly connected to the second gear ring of the second planetary row, the outer side of the outer ring is fixedly connected to the low-speed motor rotors of the low-speed driving motors, and the right end of the second planetary carrier of the second planetary row is fixedly connected to the output shaft.

Description

technical field [0001] The invention relates to a continuously variable speed vehicle, in particular to a dual-motor continuously variable speed vehicle power system. Background technique [0002] The dual-motor continuously variable vehicle has the advantages of energy saving and emission reduction, and can realize stepless transmission, so that there is no impact in the shifting process. At present, the common dual-motor continuously variable transmission vehicle power system includes a high-speed drive motor, a low-speed drive motor and the first planetary row, which can realize stepless transmission. Small, so that the high speed of the high-speed drive motor is not high enough, and the low speed of the low-speed drive motor is not low enough, so that the work efficiency of the high-speed drive motor and the low-speed drive motor is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-motor continuous...
