Description
Technical field
The utility model belongs to new-energy automobile field, more particularly to hybrid power coupled system and vehicle.
Background technique
Dynamical system includes engine (internal combustion engine) and a power train being made of speed changer, differential mechanism and transmission shaft
System；Its effect is driving power needed for providing driving wheel to vehicle.Internal combustion engine has certain speed and torque range, and
Wherein reach optimal working condition in the range of very little, at this moment or oil consumption is minimum or noxious emission is minimum or two
All so.However, actual road conditions are ever-changing, in the speed for not only showing driving wheel, while being also manifested by required by driving wheel
Torque.Therefore, realize that revolving speed and the torque of internal combustion engine are optimal, i.e. power optimum state, the matching with driving wheel dynamic regime
It is good, it 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 internal combustion engine between two adjacent speed ratios.It is stepless
Speed changer, either mechanically, one electric-type of fluid pressure type or machine, unlimited can be provided in certain speed range continuously may be used
The speed ratio of selection, in theory, the velocity variations of driving wheel can be completed completely by speed changer.In this way, internal combustion engine can use up
Possible work is in optimized range of speeds.Stepless transmission is compared with step change transmission simultaneously, has speed regulation steadily, can be sufficiently
Many advantages, such as using internal combustion engine maximum power, therefore, stepless transmission are always pair of various countries' engineers research for many years
As.

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 motor serial hybrid system, one shafting of internal combustion engine one generator, one motor, one driving wheel composition one is concatenated
Power transmission chain, power assembly structure are extremely simple.Wherein, one motor of generator combination can be considered the speed changer under traditional sense.
When with accumulator, such as battery, when capacitor etc. is used in combination, the speed changer but also as energy conditioner, complete 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 one battery system of motor.Mechanical transmission is responsible for completing the adjusting to speed, and one battery system of motor is then completed
Adjusting to 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 since whole power pass through generator and electricity
Motivation, therefore the power requirement of motor is high, volume is big, weight weight.Simultaneously as energy transport is electric by machine one twice,
The conversion of an electric machine, the efficiency of whole system are lower.In parallel hybrid system, only partial power passes through electric system, because
This, it is relatively low to the power requirement of motor.Total system it is high-efficient.However, this system needs two sets of independent subsystems, make
Valence is high.It is generally only used for Weak mixing system.

The inner peripheral surface of component, output gear and distribution output block are integrally provided to the outer peripheral surface of the distribution output block, and defeated
Bearing overlaps in the axial direction with rotor bearing out.By reasonably controlling associated power source, pure electric vehicle may be implemented and mixing
Close drive mode, 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 less desirable with economy.
