Abstract

The invention relates to an efficient multi-mode hybrid power heavy truck power assembly. The power assembly is characterized by comprising an engine, a first brake, a planetary gear set, a second brake, a generator, a driving motor, inverters, a driving battery, a two-gear gearbox, a gearbox and an output shaft, wherein the engine is in rigid connection with a planetary carrier of the planetary gear set through the first brake, a sun gear of the planetary gear set is rigidly connected with the generator through the second brake, a gear ring of the planetary gear set is coaxially connected with the input end of the gearbox and the driving motor through the output shaft, the generator and the driving motor are connected to the power battery through the inverters connected with each other, and the two-gear gearbox is connected with the driving motor through the output shaft. The efficient multi-mode hybrid power heavy truck power assembly has the advantages of being scientific and reasonable in design, high in oil saving rate, simple in structure, low in development cost, easy to realize, and high in innovativeness.

Description

technical field [0001] The invention belongs to the field of transmission machinery and relates to a power assembly, in particular to a high-efficiency multi-mode hybrid heavy-duty truck power assembly. Background technique [0002] At present, when domestic and foreign car companies are committed to the research and development of hybrid technology, they have different technical routes. From the degree of hybridization, there are mainly three technical routes: micro-hybrid, medium-hybrid, and strong-hybrid. Among the three, the micro-hybrid has a relatively small investment, and the strong-hybrid has a significant fuel-saving effect and has certain subsidies. It has obvious advantages in China. The structure of the medium-hybrid is more complicated and the investment is relatively large. Japanese cars mostly use this technology. There are three main solutions to deal with the three technical routes: the first type adopts the 48-volt light-hybrid solution, which has the func...
