Abstract

The invention discloses a dual-motor integrated hybrid-power transmission device. The device includes a shell, a power input shaft, a power output shaft, a first sleeve shaft, a second sleeve shaft, afirst motor and a second motor; the power input shaft is arranged in the shell, the tail end of the power input shaft is provided with a planetary frame, and the planetary frame is provided with a long planet wheel and a short planet wheel meshed with each other; the power output shaft is arranged at the other end of the shell, the power output shaft is connected with a gear ring, and the short planet wheel is meshed with the gear ring and the long planet wheel at the same time; the power input shaft, the first sleeve shaft and the second sleeve shaft are arranged together in a sleeving mode,the first motor is connected with the gear ring through the first sleeve shaft, a large sun wheel, the long planet wheel and the short planet wheel, the second motor is connected with the gear ring through the second sleeve shaft, a small sun wheel and the short planet wheel; the first motor and the second motor are integrated in the shell. The transmission device is more compact in structure, higher in transmission efficiency and simple in cooling system.

Description

technical field [0001] The invention relates to the field of hybrid power, in particular to a dual-motor integrated hybrid power transmission device. Background technique [0002] Due to the increasing global energy shortage and environmental pollution, more and more attention has been paid to the exhaust emissions and energy consumption of automobiles, and the pressure on energy saving and emission reduction of automobiles is increasing. Environmentally friendly electric vehicles or fuel cell vehicles have emerged as the times require. However, due to the constraints of some key technologies, it is difficult to fully promote electric vehicles or fuel cell vehicles in a short period of time. Therefore, hybrid vehicles that are more mature in technology are currently an ideal choice. [0003] Hybrid Vehicle (HEV) is a relatively new energy-saving and environment-friendly vehicle. Its technology and market are in a mature stage of development. Compared with hybrid vehicles, tr...
