Description

Series connection type hybrid power system
Technical field
The present invention relates to a kind of series connection type hybrid power system that is widely used in varying duty varying load engine installation, it belongs to the engine installation field of communications and transportation.
Background technology
As everyone knows, in hybrid power system, the transmission of power has three kinds of modes, i.e. series system, parallel way and series-parallel connection mode.Series system is to use engine driven generators, electrical generator comes driving motor by the electric power that sends, come drive wheels by electrical motor, adopt this mode, can make the less driving engine of horsepower output in the actv. scope than runs steadily, vehicle can also carry out battery charge on one side effectively, Yi Bian travel.And parallel way is with driving engine and wheel driving motor, and this mode can be used two kinds of power respectively according to travel conditions.Toyota's hybrid power system is combined the strong point separately of having brought into play the two preferably with parallel way and series system.This hybrid power system is ad hoc planetary wheel, comparatively speaking, the control of hybrid power system is comparatively complicated.
Summary of the invention
In order to make the hybrid power system for automobile structure more efficient, the invention provides a kind of series connection type hybrid power system, this hybrid power system should adopt the tandem actuating device, realizes Comprehensive Control by the ECU control unit.Mechanical Driven partly is taken to the driving engine that rare two driving engines are formed.By the ECU control unit total system is optimized control, makes vehicle have good dynamic property, economy and discharge index simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of series connection type hybrid power system, it mainly comprises an actuating device, actuating device is connected in turn by electrical motor, diff, semiaxis and wheel, and provides power by engine driven generators to electrical motor.It also comprises an ECU control unit.Above-mentioned driving engine has at least two driving engines to link together by power-transfer clutch, high-pressure oil pump, water pump and lubricating oil pump are installed on the driving engine that has output shaft, high-pressure oil pump is connected with the fuel injector of each cylinder through high pressure fuel pipe, water pump has water supply pipe to connect each driving engine, lubricating oil pump also has fuel feed pipe to connect each driving engine, and the oil pan tray of each driving engine is communicated with by connection pipe.Electrical generator, electrical motor, electric energy change over controller and storage battery adopt and are electrically connected, and ECU control unit and driving engine, tachogen, car speed sensor, electric energy change over controller, power-transfer clutch and electrical motor adopt and be electrically connected.A kind of method of above-mentioned driving engine is to be taken to rare two driving engines to use the power-transfer clutch mono-axial to be connected in series, or a driving engine is divided into two cylinder groups at least, is cascaded with power-transfer clutch on the bent axle between the cylinder group; Also can be taken to rare two driving engines uses power-transfer clutch multiaxis line parallel to connect.
The guiding theory of technique scheme is: this hybrid power system can adopt several driving engines to make up, when extraneous load variations, certain driving engine is engaged or separation, allow the load and the extraneous load of driving engine output adapt, this just can guarantee that live engine always is in good performance state.Therefore this hybrid power system has broad more high efficiency scope, can satisfy fully from the express highway to the urban highway, and the use from fully loaded to different operating modes such as zero loads needs.
The invention has the beneficial effects as follows: this hybrid power system mainly comprises a tandem actuating device.Because driving engine has at least two driving engines to form, allow the load and the extraneous load of driving engine output adapt, engine control is moved at high efficient area, hybrid power system efficient is further enhanced.Both reduced pollution, utilized the energy again rationally, efficiently environment.
