Multi-mode hybrid power transmission device and vehicle comprising same

Abstract

The present invention relates to a hybrid power transmission device, and the device comprises a first shaft capable of receiving power from a first power source; a second shaft which can receive power from the second power source and the third power source; a third shaft which is parallel to the first shaft and the second shaft and can receive power from the second shaft; gears which are distributed on the first shaft, the second shaft and the third shaft; and a second shaft switching element which is arranged on the second shaft and used for changing the connection state of a gear on the second shaft and the second shaft; wherein the power output path of the first power source passes through the gear on the first shaft, the gear on the second shaft and the gear on the third shaft. According to the structural arrangement of the present invention, when the power transmission route of one motor as the main drive motor is transmitted to the wheels, the transmission route of the internal combustion engine is multiplexed, so that the number of parts can be reduced, thereby reducing the volume and lowering the cost.

Description

technical field [0001] The invention belongs to the field of vehicles, and in particular relates to a multi-mode hybrid transmission device and a vehicle containing the device. Background technique [0002] With the reduction of fossil fuel energy and the stricter emission regulations in various countries, the technology of using clean energy to drive vehicles has begun to be applied on a large scale. According to different energy sources, in addition to traditional fuel vehicles, new energy vehicles can be divided into pure electric vehicles, hybrid vehicles and fuel cell vehicles. In practical applications, pure electric vehicles are promoted on a large scale in my country. Although the current nominal mileage can reach five to six hundred kilometers, it is affected by factors such as high battery cost, few charging stations, and slow charging speed. Due to constraints, pure electric vehicles still have problems such as insufficient cruising range and rapid battery perform...

AI Technical Summary

Problems solved by technology

[0008] 3. There is no disengagement device between the driving motor and the output shaft, and the driving motor cannot be disengaged when the vehicle is dragging and sliding backwards, resulting in backward dragging losses;

[0009] 4. The pure internal combustion engine drive mode (fuel mode) has only 1 or 2 gears, and the high-efficiency working range of the internal combustion engine cannot be well matched, which limits the working time of the internal combustion engine
