Description
Technical field
The present invention relates to the hybrid power CVT of a kind of automotive power more particularly to a kind of efficient energy-saving safe is stepless
Speed change system.
Background technique
As growth, the vehicle exhaust emission pollution of global energy anxiety and motor vehicle increasingly cause air quality low
One of key factor, to reduce vehicle exhaust emission, achieving energy-saving and emission reduction purposes, become and be engaged in vehicle manufacture enterprise and actively grind
The power-driven system that there is high efficiency, low vehicle to discharge is sent out, energy-saving and emission-reduction developing direction is reached.And as domestic and international government is to combustion
The discharge management of oily vehicle is increasingly stringenter, and vehicle exhaust emission is primarily to solve the problems, such as dynamical system, therefore hybrid power is opened
Beginning has mixed dynamic, the parallel mixed dynamic and series parallel type of tandem mixed dynamic.The hybrid vehicle and new energy vehicle of fuel-efficient environmental protection start
By more consumers and receiving, hybrid vehicle the direction of energy-saving and emission-reduction also obtain domestic and international government encouragement and
It supports.
1, Toyota Motor does not release Series-Parallel HEV in 20th century, overcomes engine in initial start-up conditions
Under emission control and power demand difficulty, hybrid power system design be using double-motor power shunt and planetary gear
Coupling scheme, vehicle is in braking kinetic energy and inverse cyclic process recycling energy storage back electric quantity rechargable battery group, effective recycling energy circulation
It utilizes, there are still following disadvantages for design:
(1.1) design of Toyota THS structure includes No. 1 engine, No. 1 motor, No. 2 motors, planetary gear, control motor tune
The corresponding engine speed of full line star tooth reaches variable speed, and speed changing structure design control is complicated, not CVT variable speed,
Do not have the superior starting power of CVT infinitely variable transmission and accelerate smooth performance, when engine operation and the planetary gear of motor
Always decoupling can not be separated, increases the related gearing resistance of motor when starting work, energy consumption is during multiple conversions by resistance
Consumption and waste, motor power recycling can only in the braking state under small hair power generation recharge, recharge that electricity is limited, and system is not
Have direct insertion charge function, cause vehicle-mounted electric energy energy storage limited, electric drive cruising ability is insufficient, and vehicle driving is substantially with fuel oil
Based on engine power, electric drive helped for pair, and engine start and stop excessively frequently, in terms of system and discharge control difficulty pole
Greatly, energy recovery is unable to reach efficient utilization.
2, the planetary gear coupling technique hybrid power system of Toyota Motor is got around, other hybrid variable-speeds are more
Its design of mode Direct Driving System directly removes transfer gear box, by engine, generator, driving motor, clutch, differential
Device, battery pack, control circuit composition.Fuel engines fires when load-carrying, climbing, large torque output for work of running at high speed
Oil turbine cooperates, and multiple motor combinations, has the following disadvantages:

Can loss quickly, continuous work will lead to battery group from over discharging, when battery be in low-voltage output electric current also double increasing,
It will lead to battery, motor, control element aging rapid wear, multiplication high current can puncture the damage or short of motor or control element moment
Road, fuel engines will have no way of changing output power transmission ratio in removal gearbox, lose the power output of low rotation speed large torque
Performance advantage, fuel engines working efficiency is extremely low at this time, output torque is minimum, only will increase oil consumption and discharge, and system uses
Dental inlay electromagnetic clutch will appear delay jitter when separation/engagement between differential box, engine/motor is in middle high revolving speed work
The Detaching and Lapping impact force that its moment is frequently separated/engaged between work will lead to clutch overaging and rapid wear, and system
Multiple design of electrical motor combinations, structure is complicated, and manufacturing cost is higher, when controlling and travel in use inevitably has the control court of a feudal ruler or does not assist
Same stationary problem.Difficult point is solved in the presence of very big technology.
3, current CVT variable speed box structure designs simple, superior performance, is driven using front and back V-type band cone pulley and V-type
With being formed, changing front and back deep trouth of the V-type with cone pulley and diameter, to continuously change transmission ratio, compared to the letter of gear shift box structure
List, superior performance, speed change acceleration are smooth, but the design of CVT infinitely variable transmission has the following disadvantages:
(3.1) anxious to accelerate or V-belt and front and back V-arrangement driven cone pulley friction moment skid the skill of stall when large torque works
The input terminal that art defect, i.e. fuel power and motor power pass through CVT is exported by output shaft again after speed, and there is cvt
Load weight, power change big, and aging or abrasion of the V-belt in the continuous change course of work, can cause vehicle travelling at fracture
It loses transfer motion power suddenly in the process, have no way of accelerating, lead to dangerous traffic safety hidden danger.
