Abstract

The invention relates to an electromechanical combined transmission device. The electromechanical combined transmission device is characterized by consisting of a mechanical transmission module and anelectric transmission module, wherein the mechanical transmission module comprises an input shaft, a middle shaft, an output shaft, a first clutch, at least two forward gear sets and forward adapters, wherein the forward gear sets carry out speed-variable transmission from a low speed to a high speed. The electric transmission module comprises a power generator, an electric motor, a second clutch, an electric motor shaft, an electric transmission shaft, a direct driving gear, a series-driving gear, an electric transmission connector, a current condenser and a power controller. According to the scheme, four different transmission modes can be formed by setting the working states of the clutches and the adapters and using the power controller for controlling the working states of the powergenerator, electric motor and current condenser, the advantages of reliable and efficient mechanical transmission, large power density of electric transmission, easy realization of stepless speed changing and the like are brought into play conveniently, the defects of mechanical transmission and electric transmission are avoided at the same time, and the electromechanical combined transmission device is suitable for loading different types of vehicles.

Description

technical field [0001] The invention belongs to the field of vehicle transmission, and in particular relates to an electromechanical composite transmission device which uses an internal combustion engine as a power source and comprehensively applies mechanical transmission and electric transmission. Background technique [0002] According to different functions and applicable occasions, vehicles can be roughly divided into two categories: road vehicles and non-road vehicles. Road vehicles are all kinds of vehicles used to transport passengers and goods on the artificial road network; non-road vehicles are all kinds of self-propelled construction machinery, agricultural equipment, construction machinery, special operation machinery and Non-road transport vehicles, military vehicles, etc. Whether it is a road vehicle or a non-road vehicle, it is necessary to control the driving speed to meet the work efficiency and quality requirements in different work scenarios during the w...
