Technical field
The present invention relates to simultaneously shaft type hybrid connected structure hybrid power system for automobile and the method for work of a kind of magnetic couple.
Background technology
In recent years, motor vehicle exhaust emission oneself become one of important sources of urban atmospheric pollution.Petrolic
High thermal efficiency is 33% about, and the region more than 30% is exactly the restricted working region of engine.Currently, automobile power system
In system, the 13% of fuel energy is used for travelling, and remaining 87% is used as driving accessory and becomes thermal losses and be diffused into air
In.Simultaneously as the urban traffic conditions of day by day congestion, automobile engine is led to work long hours in the less efficient slow-speed of revolution
Deng off-design point, not only exacerbate automobile energy consumption, and the discharge of noxious pollutant is continuously increased, lead to urban air environment continuous
Badly.In view of a large amount of consumption of the non-renewable resources such as oil, the pollution to environment for the orthodox car exhaust emissions, environmental protection and energy saving
Cry grow to even greater heights, research environmental protection, energy-efficient automobile dynamic system is very urgent.

In the conversion process of energy of energy, energy transmission loss is larger, there is also energy and damage during the charge and discharge of power battery pack
Consumption, the total overall efficiency of energy conversion is lower than internal-combustion engines vehicle.
In parallel system, engine separately can provide power to automobile driving wheel with motor, does not connect
Generator in formula HEV PWTN, the mechanical energy of engine can be directly output to automobile drive axle, and centre does not have energy
Conversion, with tandem arrangement compared with, system effectiveness is higher, and fuel consumption is also less.But due to engine and driving wheel of vehicle
Between have direct mechanical connection, engine operation condition is inevitably affected by the concrete driving cycle of automobile.
Combined hybrid system is tandem and parallel synthesis, and it has given full play to the advantage of series and parallel, can
The parts such as engine, generator, motor are made to carry out more Optimized Matchings, thus ensure that in structure in more complicated work
Remain under condition make system work under the optimal condition.But its structure is extremely complex, its match control is also very difficult simultaneously.
In sum, current hybrid power system is not well positioned to meet the demand of advanced environment-friendly energy-saving automobile, compels to be essential
Develop new hybrid power system technology, effectively overcome that the efficiency in low speed and off-design point for the engine is low, discharge is dirty
Contaminate high problem, realize green high-efficient and the energy-conserving and environment-protective of automobile.
