Description
Technical field
The present invention relates to electric automobiles, particularly a kind of machine that reverses gear manually of motor rear axle driving automatic speed changing motor
Structure.
Background technology
Electric control mechanical type automatic speed variator（Automated mechanicalTransmission, abbreviation AMT）, AMT changes
The feature of speed system and operation are well known in the art, such as AMT has the advantages that driving comfort, reduction driver are tired,
Electric car equipped with automatic transmission can absorbedly watch road surface attentively according to pavement behavior automatic speed-changing and torque-converting, driver
Without doing in a rush because of gearshift, AMT fluid drives can be such that driver is realized in the case of power is not cut off for traffic
Fluid drive.
Electric car green, environmental protection, run cost are low, and deep to be liked by user, electric-powered not only unit mileage usage charges are low,
And meet low-carbon emission reduction requirement, it is the major project of China 863 and the 12nd five-year plan, annual requirement is continuous
Lifting.
Known electric vehicle motor, there is hub-type, gear shift motor.Hub-type motor is one to one transmission, gear change
Speed motor is that direct motor drives gear, and there is rotating speed and the immutable defect of moment of torsion, use are existing for this transmission mode
Motor assembling electric car, can not realize the increased climbing demand of more times of moment of torsion, the particularly electric car and load in some mountain areas
The application of weight electric vehicle；Such as electro-tricycle or electric four-wheel vehicle.
As electric power, in operation compared with fuel combustion vehicle, its energy is to be compensated, so system effectiveness
As electrodynamic key index, either fuel oil or electronic, it has peak efficiency to use space, and designer is usually highest
Efficiency section is as nominal operation efficiency, and only in this state, it is most energy saving, therefore, is changed in use using machinery
Gear can change electric efficiency curve, not only be satisfied with operation demand, and use big speed ratio on startup, make less output
Power obtains larger output torque, effectively protects storage battery.
Electrodynamic automatic Transmissions Technique, the direct effect played is exactly to allow fool to drive arbitrarily to shift gears, no matter very fast
Or climb, due to changing motor operation curve after switching gearratio, system is in high efficiency section and runs, and simple in structure,
Manufacture cost is lower, the degree of automation higher, it can be made by speed changer according to electric vehicle speed and run slowly, and increase is defeated
Go out torque.
At present, the electro-tricycle in China, electric four-wheel vehicle generally drive rear axle shaft to realize driving using differential speed motor,
This transmission mode directly drives gear-box for motor, when vehicle makees backward running, if making motor reversal can implement, but
Its load running can not change speed and moment of torsion with environment as said before.
China is incorporated herein and opens 201110029082.9 electro-tricycle of Patent No. of public affairs, electric automobile fluid drive
The patented technology of motor transmission mechanism, the technology in the process of running, have no the solidifying need that can be realized with speed and load asked
Ask, still, which does not make description further, only made unidirectional drive or two-way to construction part of reversing gear
Type of drive is run, but, in the technical solution of the patent, if using unidirectional drive to drive disk, it will be in power-off shape
Under state, gearbox can be made to depart from magnetic resistance of motor, the coasting distance of vehicle will be farther, can increase the continuous of electric car single charge
Row ability.
In order to solve the patent of 201110029082.9 electro-tricycles, electric automobile automatic speed change motor transmission mechanism
The problem of reversing gear of technology, the small-power AMT automatic speed regulating differential motors of Patent No. 201410142554.5 are proposed by electromagnetism
Valve promotes telescopic rod to realize bi-directional drive to the intersection of limited post, although the technology solves 201110029082.9 electronic three
Take turns car, electric automobile automatic speed change motor transmission mechanism patented technology problem of reversing gear, but in practical applications, if driven
After the person's of sailing reversing terminates or the longer time does not cut off the switch that reverses gear in time, it will and cause solenoid valve to be constantly in normally opened,
Make to cause fever under electromagnetic coil is in running order for a long time or even burn out.
The content of the invention
The present invention in order to solve in order to solve 201110029082.9 patented technologies there are the defects of, there is provided it is a kind of to fall manually
Retaining device is combined with unidirectional drive disk, and vehicle can be made often to use unidirectional drive when driving, and it is continuous to possess wheel function increase
Row mileage, when vehicle backing is run, gear is pulled out using mechanical type manual, ensures for a long time to ensure Machinery Ministry under not yet reset state
Part is without damage.
