Description
Technical field
The utility model belongs to technical field of hybrid power, more particularly to a kind of hybrid electric drive system and vehicle.
Background technique
Dynamical system generally includes engine (internal combustion engine) and a transmission being made of speed changer, differential mechanism and transmission shaft
System.Its effect is driving power needed for providing driving wheel to vehicle.Engine has certain speed and torque range, and
Reach optimal working condition in the range of wherein very little, at this moment or oil consumption is minimum or noxious emission is minimum or two
Person is all right.However, actual road conditions are ever-changing, in the speed for not only showing driving wheel, while being also manifested by driving wheel and being wanted
On the torque asked.Therefore, realize that revolving speed and the torque of engine are optimal, i.e. power optimum state, with driving wheel dynamic regime it
It matches, is the top priority of speed changer.
Speed changer currently on the market mainly has step change transmission and stepless transmission two major classes.Step change transmission segments again
It is manually and automatically two kinds.They are arranged by the different engagement of gear train or planetary gear train limited discrete to provide mostly
Output input speed ratio.The adjusting of wheel speed is driven then to realize by the velocity variations of engine between two adjacent speed ratios.It is stepless
Speed changer, either mechanically, one electric-type of fluid pressure type or machine, can be provided in certain speed range unlimited it is continuous
Available speed ratio, in theory, the velocity variations of driving wheel can be completed completely by speed changer.In this way, engine can be with
It works in optimized range of speeds as far as possible.Stepless transmission is compared with step change transmission simultaneously, is had speed regulation steady, can be filled
Many advantages, such as dividing using maximum power, therefore, stepless transmission are always the research of various countries' engineers for many years
Object.
In recent years, the birth of hybrid power actuation techniques is to realize that the exact matching of power between engine and power wheel is opened
New approach is opened up.It is most representative to have serial hybrid system and mixed stocker in parallel in numerous power assembly design cases
Two kinds of system.In serial hybrid system, Engine-Generator-motor-shafting-driving wheel forms a concatenated power
Chain, power assembly structure are extremely simple.Wherein, generator-motor combination can be considered the speed changer under traditional sense.When with
When accumulator (such as battery, capacitor etc.) is used in combination, which is completed but also as energy conditioner to speed and torque
It is separately adjustable.
Parallel system has two parallel independent power transmission chains.One is made of traditional mechanical transmission, another by
Electric machine-battery system composition.Mechanical transmission is responsible for completing the adjusting to speed, and electric machine-battery system is then completed to function
The adjusting of rate or torque.For the potential for giving full play to whole system, mechanical transmission is also needed using stepless gearing method.
The advantages of serial hybrid system, is that structure is simple, flexible layout.But whole power pass through generator and motor, because
The power requirement of this motor is high, and volume is big, weight weight.It is converted twice simultaneously as energy transport passes through, whole system
Efficiency is lower.In parallel hybrid system, only partial power is therefore, opposite to the power requirement of motor by electric system
It is lower, system it is high-efficient.However, parallel hybrid system needs two sets of independent subsystems, cost is high, is generally only used for Weak mixing
System.
For example, parallel hybrid system used by Toyota Prius, includes two motors and a planetary gear mechanism.It is logical
Reasonable control associated power source is crossed, electric-only mode and combination drive mode may be implemented.
But the parallel hybrid system of Toyota Prius only can be realized electric-only mode and two kinds of hybrid mode drives
Dynamic model formula.So that the system only suitable for city operating condition and carriage type, for non-city operating condition and compared with large-scale vechicle, dynamic property
It is all undesirable with economy.
