Description

A kind of novel oil electric mixed dynamic system

Technical field

The utility model relates to a kind of automobile dynamic system, and especially relating to a kind of is the hybrid power system of the energy with fuel oil with electricity.

Background technology

Because the fuel oil power vehicle is to the pollution and the energy resource consumption problem of environment, electronlmobil and hybrid vehicle are the emphasis of motor field current research and development.

Usually said hybrid power generally is meant oil electric mixed dynamic, be fuel (gasoline, diesel oil) and the mixing of electric energy, hybrid vehicle is to have electro-motor to drive automobile as the auxiliary power of driving engine, the fuel-economy performance height of hybrid vehicle, and rideability is superior, the driving engine of hybrid vehicle will use fuel oil, and in starting, when quickening, since the auxiliary of electro-motor arranged, thus oil consumption can be reduced, briefly, compare with onesize automobile exactly, fuel cost is lower.And the electro-motor of auxiliary engine can produce powerful power in the moment that starts, and therefore, the car owner can enjoy more powerful starting, acceleration.Simultaneously, can also realize the fuel economy of higher level.

The kind of hybrid vehicle mainly contains 3 kinds at present:

1, a kind of is to be active force with the driving engine, and electro-motor is as " parallel way " of auxiliary power;

This mode is mainly travelled with engine drive, produce the feature of very strong driving force when utilizing restarting that electro-motor has, when engine fuel consumption such as vehicle starting, acceleration are big, reduce the oil consumption of driving engine with the mode of electro-motor assistive drive, this mode relatively simple for structure only need increase electro-motor and storage battery on automobile.

2, another is, only travels " the series, parallel mode " that driving engine and electro-motor matched and drive when speed improved when low speed by electrical motor driven;

Be only to travel by electrical motor driven when startup and low speed, when speed improves, share power jointly efficiently by driving engine and electro-motor, this mode needs power sharing device and electrical generator etc., so complex structure.

3, also having a kind of is the electronlmobil " series system " that only travels with electrical motor driven;

Driving engine is only as propulsion source, and automobile only travels by electrical motor driven, and drive system is an electro-motor, but because need equally engine fuel is installed, so also be a kind of of hybrid vehicle.

From degree of dependence to electric energy, hybrid power can be divided into Weak hybrid power MILD HYBRID and (also claim light hybrid, soft hybrid power, micro-hybrid etc.), the moderate hybrid power, severe hybrid power FULL HYBRID (also claiming full hybrid power, strong hybrid electric etc.), plug-in hybrid power PLUG IN HYBRID.

The power system of present hybrid vehicle and version have series, parallel and three kinds of forms of series-parallel connection, the IMA parallel system of the Insight of Japanese honda company for example, with THS combined hybrid system of the Pirus of Toyota Company etc., wherein, the IMA system architecture of the Insight of Honda company is simple, but motor only possesses additional function, do not possess pure some driveability, belong to the Weak hybrid power form, the THS combined hybrid system of the Pirus of Toyota Company possesses the ability of pure motor driving, but its power combination mechanism complexity, volume is big, manufacturing cost is high.

Existing a kind of hybrid vehicle system comprises combustion engine, motor, power-transfer clutch, change-speed box, electrokinetic cell, brake system and car load autonomous cruise speed system.This design has been simplified some a little than original structure, and has the ability of pure motor driving, but its defective still exists: assembly is too much, and difficult arrangement, the dynamic property of vehicle, fuel economy and emission behavior also can't be satisfactory, needs further to improve.

Summary of the invention
