Abstract

The invention discloses an adjustable speed transmission system for a hybrid power vehicle, and belongs to the field of hybrid power vehicles. The adjustable speed transmission system includes an engine, an adjustable speed transmission device for transmitting power and automatically changing a transmission ratio, a first motor, a second motor, a first clutch and a supporting disc, wherein the first motor is electrically in parallel connection with the second motor, the engine is in transmission linkage with the first clutch through the supporting disc, and the supporting disc is also in transmission linkage with the first motor. The first clutch is in transmission linkage with the adjustable speed transmission device. The adjustable speed transmission device is in linkage with wheels through a first transmission shaft, and in linkage with the second motor through a second transmission shaft. By adopting the adjustable speed transmission system, the power of the engine after the engineis in coupling with the first motor can be transmitted smoothly without generating impact on the vehicle, and the comfortableness is ensured for passengers.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a variable speed transmission system for hybrid electric vehicles. Background technique [0002] With the increasing scarcity of energy and the increasingly prominent environmental problems, energy conservation and environmental protection issues are particularly important. Traditional cars rely on burning fossil fuels (such as gasoline, diesel, etc.) to provide power for the engine, and the exhaust gas will pollute the environment, which does not meet the requirements of energy saving and environmental protection. However, pure electric vehicles have a short cruising range and incomplete supporting facilities, which cannot meet people's travel needs. Therefore, it is necessary to use a hybrid vehicle with the characteristics of energy saving, environmental protection, and long cruising range, and in order to improve energy efficiency, it is very necessary to provide a tr...
