Problems solved by technology

Moreover, commercial vehicles require more working modes than sedans, and the working conditions are relatively more complicated. If a hybrid power transmission system of a sedan is used for a commercial vehicle, it cannot meet its driving needs at all. start, which puts higher demands on the transmission system

Abstract

The invention relates to a double-planetary-mechanism hybrid power automobile transmission system which comprises an engine, a transmission, a main reducing gear and a differential mechanism. The differential mechanism comprises a first planetary mechanism, a second planetary mechanism and a gear block mechanism arranged between the first planetary mechanism and the second planetary mechanism. A power coupling device of double motors and double planetary wheel mechanisms is adopted, the motor speed regulation range is optimized, the transmission ratio range is expanded, the dynamic property of a second motor is improved, different work modes can also be selected according to the vehicle load and the situation of changeable use conditions, the requirements for the dynamic property and economy of vehicles is better met, and the double-planetary-mechanism hybrid power automobile transmission system is particularly suitable for commercial vehicles.

Description

technical field [0001] The invention belongs to the field of automobile transmission systems, and in particular relates to a double planetary mechanism hybrid electric vehicle transmission system. Background technique [0002] Hybrid electric vehicles have the advantages of improving environmental pollution, oil crisis, and reducing the cost of vehicle use. Therefore, at present, automobile manufacturers all over the world focus on hybrid electric vehicles as their development targets. [0003] At present, the development of hybrid passenger vehicles is relatively good, and there are few researches on hybrid commercial vehicles in China, and the development is urgent. Hybrid trucks, buses, garbage trucks, etc. have a common feature. The running state of the vehicle is obviously different when it is fully loaded and empty, and its power performance, economic performance, and emission performance are different under different working modes. Moreover, commercial vehicles requi...
