Description
Technical field
The utility model relates to field of new energy technologies, in particular to a kind of hybrid electric drive system.
Background technique
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 internal combustion engine between two adjacent speed ratios.It is stepless
Speed changer, either mechanically, fluid pressure type or mechanical, electrical formula, unlimited can be provided in certain speed range continuously can be selected
Speed ratio, in theory, the velocity variations of driving wheel can be completed completely by speed changer.In this way, internal combustion engine can be as far as possible
Work in optimized range of speeds.Stepless transmission is compared with step change transmission simultaneously, is had speed regulation steady, can be made full use of
Many advantages, such as internal combustion engine maximum power, therefore, stepless transmission are always the object of various countries' engineers research for many years.
In recent years, the birth of electric machine mixed power technology is to realize that the exact matching of power between internal combustion engine and power wheel is opened
New approach is opened up.It is most representative to have serial hybrid system and mixing in parallel in numerous power assembly design schemes
Two kinds of system.In motor serial hybrid system, internal combustion engine, generator, motor, shafting, driving wheel composition one are concatenated dynamic
Riding chain, power assembly structure are extremely simple.Wherein, generator, motor combination can be considered the speed changer under traditional sense.When with
Accumulator, such as battery, when capacitor etc. is used in combination, which is completed but also as energy conditioner to speed and torque
It is separately adjustable.
Motor parallel system has two parallel independent power transmission chains.One is made of traditional mechanical transmission, another
Item is made of motor, battery system.Mechanical transmission is responsible for completing the adjusting to speed, and motor, battery system are then completed pair
The adjusting of power 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,
Therefore the power requirement of motor is high, and volume is big, weight weight.Simultaneously as energy transport process is electromechanical twice, motor turns
It changes, the efficiency of whole system is lower.In parallel hybrid system, only partial power is by electric system, therefore, to motor
Power requirement is relatively low, total system it is high-efficient.However, this system needs two sets of independent subsystems, cost is high.Usually only
For Weak mixing system.
