Description
Technical field
The utility model relates to a kind of technology in vehicle drive system field, specifically a kind of electromechanical hybrid power
System.
Background technique
It is faced with the challenge for constantly reducing pollutant emission in development process as the automobile of power using internal combustion engine, automobile is dynamic
Power just develops towards renewable, clean energy resource direction.Technology of Hybrid Electric Vehicle is a kind of by combustion engine powered and motor power
The technology to drive automobile is coupled in a certain way, it is that automobile power trend is completely free of to fossil fuel dependence, percent
Hundred by a kind of middle transition technology before clean energy resource.
Compared with traditional combustion engine powered technology, Technology of Hybrid Electric Vehicle can significantly improve energy utilization efficiency, reduce
Discharge.Since energy storage technology is yet to be completed, there is also expensive or small energy density deficiencies for vehicle-mounted clean energy resource, mix
The short slab of current clean energy resource actuation techniques can be made up to a certain extent by closing power technology, meet vehicle in terms of discharge
Government constantly becomes harsh laws and regulations requirement, and then can satisfy the requirement of user vehicle in terms of continual mileage, avoids
There is mileage anxiety.
The prior art mainly includes two major classes.One kind is usually adopted using technology of the planetary gear train as coupling device
It is connected in different ways with multiple power sources of input with 1 to 3 planetary gear trains, wherein typical representative patents
Including United States Patent (USP) US3566717, USB35B264 and Chinese patent CN2008100B2B20.7, CN201110185854.8.
Another major class is using technology of parallel axes (Layshaft) the formula gear train as coupling device, such as patent
CN200B301C1069.1, CN200910199960.4 etc..
In order to further increase the efficiency of hybrid power system, it is intended to increase the gear number of hybrid power system at present
Amount.In the hybrid power system using above-mentioned planetary gear train, multi-plate wet clutch or multi-sheet wet-type braking are generallyd use
The hydraulic gear-shiftings system such as device controls planetary gear, and in the hybrid power system of above-mentioned parallel-axis type gear train, lead to
It shifts gears frequently with electromechanical shift system.
The shortcomings that above-mentioned first kind planetary gear train coupling device technology, is main are as follows:
1) hydraulic oil in plunger shaft is needed to keep high pressure to provide to piston when the multi-plate wet clutch work used
Enough pressure, it is therefore desirable to which high-pressure oil pump continues fuel feeding, to improve the loss of dynamical system, and to controller and vehicle
Harness has higher requirement；
2) each executive component is required to a control oil circuit, therefore the quantity of clutch or brake is increased same
When, it can directly increase the complexity of hydraulic circuit, to improve the cost of power assembly；
3) it when pure electric vehicle operating condition is run, since engine is not involved in driving, is highly coupled by planetary gear train with it
Engine control motor (i.e. dynamotor) can not participate in driving, limit the power performance of whole device；
4) under pure electric vehicle operating condition, when only being driven with driver motor, it can only be run, not can guarantee with fixed drive ratio
Motor is often run in high efficient district, and system effectiveness is not high；
5) when speed is lower, under hybrid mode, engine control motor can only when engine participates in driving
With dynamotor mode operation, the electricity supply driver motor of sending is used, this working method makes one that engine provides
Partial power experienced mechanical energy to electric energy, again by the conversion of electric energy to mechanical energy, inefficient；
6) when speed is higher, under hybrid mode, engine control motor can only when engine participates in driving
It is run with electric motor mode, and driver motor will be with dynamotor mode operation, the electric supply engine of sending controls electricity
Motivation use, this working method also make engine provide a part of power experienced mechanical energy to electric energy, again by electric energy to
The conversion of mechanical energy, it is inefficient；
7) when engine driving dynamotor charges the battery, the operating point of engine and dynamotor is run by vehicle
The containing of operating point, the freedom degree for choosing operating point is smaller, and generating efficiency is made to be affected；
8) under coasting mode, only driver motor can participate in the recycling of energy, and at engine control motor
In idling conditions, become negatively affected the effect of braking energy feedback；
9) under braking energy feedback operating condition, in order to maximize effect, it is dynamic to generate electricity that engine controls motor needs
The operation of machine operating condition, and engine then has to enter into engine braking operation mode, this is wasted to a certain extent originally can return
The kinetic energy of receipts influences the effect of energy regenerating；
The defect of above-mentioned second class parallel-axis type coupling device technology specifically includes that
1) power transmission of motor to wheel is typically only capable to be fixed drive ratio under pure electric drive operating condition, not can guarantee
Motor is often run in high efficient district, and system effectiveness is not high；
If 2) using two motors cooperation synchronizer shift, although then may be implemented under pure electric drive operating condition double acting
Switching or double motor between power source drive jointly, but the power transmission of every motor to wheel can only be fixed biography
Dynamic ratio not can guarantee motor and often run in high efficient district, and system effectiveness is not high；
3) when system works under hybrid mode, although engine can participate in driving, due to engine
Transmission ratio to wheel be it is fixed, can not be continuously adjusted that (i.e. electric stepless variable-speed works to its operating point according to operating condition
Mode), engine-driven performance, efficiency and discharge index all can be very poor, can not play its efficiency；
4) only has the scheme of a motor for system, in the operating condition that engine driving dynamotor charges the battery
Under, containing of the operating point of engine and dynamotor by vehicle acceptable operating point chooses operating point and lacks freedom degree, make to send out
Motivation, the efficiency of dynamotor are all affected；
5) under braking energy feedback operating condition, although double motor can recover energy into power generation mode simultaneously,
Part energy can be consumed in dragging engine, thus reduce energy feedback ratio.
