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.
