Description
Technical field
Speed follower stepless transmission of the present invention, belongs to machine-building and field of automobile.
Background technique
The people for understanding automobile both knows about, and the revolving speed of automobile engine has a most economical, most efficient speed stage,
This speed stage, oil consumption is minimum, and torque is maximum.The effect of speed changer is that engine speed is being kept to be worked as far as possible in efficient speed
In the case where spending section, moreover it is possible to guarantee that automobile travels at different rates.For example, most of engine optimum speeds section is 2000
4000 revs/min are gone to, but automobile needs to travel at various speeds, in order to which the travel speed of automobile can be changed,
It is able to maintain the optimum speed of engine again, people start the revolving speed for changing output shaft using mechanical transmission, Lai Shiying road conditions
With the demand of travel speed.But the speed changer of technology, transmission ratio are restricted at present, general manual gear gearbox, most
Top gear transmission ratio is 0.85, and crawling gear transmission ratio is 4, and base ratio is 4, which means that most high-grade, if engine
3000 revs/min of revolving speed, 0.7 meter of wheel diameter, speed is 3000/0.85/4*3.14*0.7*60=116 kilometer/hour, if
200 kilometers/hour of speed is needed at this time, have to just be opened the throttle and be improved engine speed to 5200 revs/min.If risen
Gearbox is at 1 grade when step, and engine speed is at 3000 revs/min, then torque increases 4 times, speed 3000/4/4*3.14*0.7
=24.7 kilometers/hour=6.87 meter per seconds, are equivalent to the speed of hundred meters of sportsmen, it is clear that this speed is unsuitable for starting, institute
Engine speed have to be reduced.And engine is all uneconomic in low speed segment and high regime, and torque is low, speed changer increases
4 times of big torques, due to the reduction of engine speed, and have beaten very big discount.In order to solve this problem, some vehicles use
Fluid torque-converter, although torque increase when fluid torque-converter can partially solve the problems, such as low speed, its transmission efficiency is low, occupies
Space is big, and can only work when low speed, and when high speed needs locking.In order to allow engine operation in optimum speed, people are becoming
The very big time has been descended on fast device.Initial manual transmission, because there is pause and transition in rhythm or melody sense when gear shift, Shift gear moment is difficult to hold, gradually
Replaced automatic gear-box.Automatic gear-box is facing test because structure is complicated, volume is big, cost is high, oil consumption is high.Most
The CVT speed changer newly released obtains the extensive attention of industry, various countries put into huge fund and grind due to the principle using variable speed
Hair, but even to this day, there is no too big breakthroughs.The above speed changer is made a general survey of, the biggest problems are that, after all, also
It is to have a grade speed change, on each gear, what the revolving speed of engine still needed to change, otherwise speed can not continuously adjust, gear
Also can not be connected.Even the section of CVT speed changer, variable speed is also limited, high regime and low speed segment are also needed
Engine speed is adjusted to adapt to speed and road conditions.And it is frictional drive, low efficiency, easy to damage, output torque is limited.
If there is a real gamut stepless transmission, above problem will be readily solved.The stepless change of speed follower
Fast device is such speed changer, and speed adjustable range is wide, and transmission ratio can be continuously adjusted 1 between infinity；It is pure tooth
Wheel speed regulation, it is high-efficient without frictional dissipation；More valuable: it operates the signal input that need to only control a power very little
DC speed-regulating motor can obtain the power that revolving speed follows signal input motor speed to change on output shaft and be amplified several times and be
To decades of times or even hundreds times of output；It is not necessarily to clutch, solenoid valve, does not also need electronics, hydraulic, pneumatic control；Volume
It is small, light-weight, cheap.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide a kind of high performance variable speed
Device.
Speed follower stepless transmission proposed by the present invention, by output ring gear, power input planetary plate, planetary gear,
Sun gear and a signal input motor form；The output ring gear is the common ring gear of circular ring type, and the side of annulus is set
There is wheel hub, be used to support ring gear, the center on the outside of wheel hub is equipped with output shaft；The power inputs planetary plate, to support planet
The bracket of gear, shape are collar plate shape, or meet the arbitrary shape of dynamic balance property, and center is equipped with power input shaft, disk
It is provided with circular hole on face, is equipped with cylinder；Bearing is studded in circular hole on disk, is cased with bearing on the cylinder on disk；The planet
Gear, including 2 variable speed planetary gears and 2 transition planetary gears, the variable speed planetary gear coaxial circles different by two radiuses
Column spur gear composition, two different gears of radius are located at the two sides of power input planetary plate, and it is defeated that central axis passes through power
Enter the brearing bore in planetary plate disk circular hole；The transition planetary gear is slightly larger than variable speed planetary gear pinion gear for thickness
2 times of thickness of same modulus spur gear wheel is sleeved on the outer race on power input planetary plate disk cylinder；Speed change row
Gear wheel in star gear, is engaged with ring gear；Pinion gear is engaged with transition planetary gear；The sun gear is and transition
Planetary gear is with the spur gear wheel of modulus, and thickness is identical as the pinion gear thickness in variable speed planetary gear, and center is provided with circle
Hole, circular hole are sheathed on the outside of power input planetary plate rotary shaft, concentric with ring gear, power input planetary plate；Its with
Pinion gear in variable speed planetary gear is staggered in the plane, engages with transition planetary gear；When system is run, revolving speed and torque from
Power inputs the input of planetary plate input shaft, when planetary plate rotates counterclockwise, transition planetary gear in revolution counterclockwise, because with too
The engagement of positive gear, when there are speed difference, can also rotation counterclockwise, transition planetary gear is counterclockwise, and rotation will drive variable speed planetary
The rotation clockwise of gear pinion gear, the rotation clockwise of variable speed planetary gear pinion gear drive coaxial variable speed planetary gear gear wheel
Rotation clockwise will drive variable speed planetary gear gear wheel and revolve counterclockwise, become when rotating counterclockwise because of power input planetary plate
Speed planetary gear gear wheel revolves counterclockwise will drive output ring gear and rotates counterclockwise, while variable speed planetary gear gear wheel is suitable
Hour hands rotation again rotates clockwise output ring gear, in this way, in fact, the linear velocity of output ring gear is variable speed planetary
The difference of gear gear wheel revolution linear velocity and rotation linear velocity；In this way, leading in the case where power input planetary plate speed is constant
Cross the revolving speed for changing sun gear, it will change the revolving speed of output ring gear；In the ratio between ring gear radius and sun gear radius
When equal to the ratio between variable speed planetary gear gear wheel and pinion gear radius, the revolving speed for exporting ring gear will be complete with the revolving speed of sun gear
It is complete synchronous, and unrelated with the power input revolving speed of planetary plate (revolving speed that power inputs planetary plate is more than or equal to sun gear revolving speed
In the case where), at this moment, with the revolving speed of lesser power control sun gear, it can obtain and sun gear revolving speed is followed to become completely
The ring gear speed and torque of the relatively high power of change export；When exporting ring gear speed in acceleration or uniform motion, signal
Input motor is in motor-operated running state；When output ring gear speed is in deceleration regime, signal input motor, which is in, to be reversely connected back
Present brake running state.
The sun gear has a hollow shaft, and the both ends of hollow shaft are equipped with bearing, and it is defeated that brearing bore is sheathed on power
Enter on the input shaft of planetary plate, hollow shaft inner hole and the input shaft of power input planetary plate are non-contact；Hollow shaft and a signal
Input the rotor Hard link of motor；The signal inputs motor, is DC brushless motor, and rotor is p-m rotor, in rotor

It waits, changes the polarity of stator input voltages, motor can be made to enter reversing braking working condition, the dynamics of braking can equally lead to
Cross the range-adjusting of stator input voltages；Since when power input planetary plate is rotated counterclockwise with fixed speed, transition planet
The rotational velocity of gear can be because the speed of sun gear be different and different, and transition planetary gear rotational velocity directly affects
To the rotational velocity of variable speed planetary gear gear wheel, and then the speed of output ring gear is influenced, so, by changing sun tooth
The rotation speed of wheel, so that it may change the rotation speed of output ring gear；When signal input motor is in motor-operated running state, by
Battery and super capacitor are powered for it, when in reversal connection regenerative braking operating status, are charged to battery and super capacitor.In order to subtract
The load of small signal input motor reduces the power of motor, and the rotor of the signal input motor, can be set to can only be single
To rotation, it is characterised in that: signal inputs the rotor bearing of motor and the bearing at sun gear hollow shaft both ends, is one-way shaft
It holds, when power input planetary plate rotates counterclockwise, signal input rotor can only rotate counterclockwise；In this way, defeated in power
When entering planetary plate and rotating counterclockwise, the gear wheel of variable speed planetary gear, when pushing output ring gear to rotate counterclockwise, by
The effect of ring gear reaction force, when this reaction force is transmitted to the transition planetary gear gear teeth, transition planet pinion gear teeth
Clockwise moment can be generated to sun gear, this clockwise moment is the resistance of the signal input motor rotated counterclockwise, but
Because the effect of unilateral bearing, clockwise moment are all undertaken by unilateral bearing, the burden of signal input motor is alleviated；Signal
The device that motor is equipped with detection rotor torque is inputted, when torque is more than setting value, stop pulse power supply, the purpose is in the sun
When gear is excessive by the clockwise torque that transition gear applies, torque is born by unilateral bearing, mitigates motor pressure, saves electricity
Pond energy consumption.
Speed follower stepless transmission described above is fixed sun gear, when cancelling signal inputs motor by setting
Set different gear radius, it will as transmission ratio 1 to what can arbitrarily be set between infinity, the super large of fixed no-load voltage ratio is driven
Compare speed changer；Planetary plate as input, ring gear as output when, can super large multiple torque is amplified, revolving speed reduce；Ring gear
As input, when planetary plate is as output, can super large multiple torque is reduced, revolving speed amplification.

Speed changer be it is indispensable on mechanical equipment and the various vehicles, traditional speed changer is the tooth by different radii
Wheel engagement, realizes speed change using the principle of lever.Because the radius of gear can not change, therefore the transmission ratio of speed changer is usual
All it is fixed and invariable.However the revolving speed that people are frequently necessary to change load have to change original because transmission ratio is immutable
The revolving speed of motivation.Then there is variable-speed motor, frequency converter；Occur having the gearbox of gear on automobile.But these methods
All in place of Shortcomings.Various motor speed regulators, frequency converter are not only expensive, but also high failure rate, and the service life is short.It is more tight
Weight, they are the largest source of pollution of harmonic pollution in electric power net.The speed change of automobile be it is necessary, become from hand gear to automatic
