Description
Technical field
Variable diameter gear stepless speed variator 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
Turn -4000 revs/min, but automobile needs to travel at various speeds, in order to can change automobile travel speed and
Be able to maintain the optimum speed of engine, people start the revolving speed for changing output shaft using mechanical transmission, Lai Shiying road conditions and
The demand of travel speed.But the speed changer of technology, transmission ratio are restricted at present, general manual gear gearbox, highest
Fast shelves 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 turns
3000 revs/min of speed, 0.7 meter of wheel diameter, speed is 3000/0.85/4*3.14*0.7*60=116 kilometer/hour, if this
When need 200 kilometers/hour of speed, have to just open the throttle and improve engine speed to 5200 revs/min.If starting
When gearbox at 1 grade, engine speed is at 3000 revs/min, then torque increases 4 times, speed be 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 variable diameter gear
Fast device is such speed changer, full range velocity modulation, without dead point；It is the speed regulation of pure gear, without frictional dissipation, efficiency
It is high；It is more valuable: its operate need to only change variable diameter control panel angle can full range velocity modulation, it is simple, directly；Without from
Clutch, solenoid valve do not need electronics, hydraulic, pneumatic control yet；It is small in size, 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.Variable diameter gear stepless speed variator proposed by the present invention, is composed in series by speed change grade and amplifying stage.Speed change grade is one by several
The planet tooth that reducing ring gear, reducing planetary gear set and an output sun gear for a gear valve composition forms
Take turns gear.Gear valve passes through the angle change of variable diameter control panel, can radially slide, form the ring gear of different radii,
Reducing planetary gear set, by planet carrier, free swing arm, center transmission gear, free planetary gear set at；Planet carrier be with
The bracket of multiple frame arms, central shaft are input shaft；When its work, with input shaft high speed rotation, when rotation, it is mounted on frame
The free swing arm on arm top can be flared out because of the effect of centrifugal force；When opening, it is mounted on the free walker on free swing arm top
Star gear keep engage with center transmission gear while, can around center transmission gear rotation, rotation the result is that: freedom
Planetary gear can be adjacent to reducing ring gear, engage with the holding of the gear valve of the ring gear of any radius；It is counterclockwise in planet carrier
When rotation, because ring gear is fixed, free planetary gear, can also rotation clockwise while revolution counterclockwise；Free planet tooth
It takes turns rotation clockwise and will drive center transmission gear and rotate counterclockwise, center transmission gear rotates counterclockwise will drive output shaft too
Positive gear rotates clockwise, it is such the result is that: the steering of output shaft sun gear and planet carrier is on the contrary, output shaft sun gear
Linear velocity be center transmission gear revolve linear velocity subtract center transmission gear rotation linear velocity；In this way, passing through reasonable set
The radius of center transmission gear gear wheel and pinion gear, configures suitable no-load voltage ratio, and the radius by changing ring gear can be realized,
Realize output shaft revolving speed from the smooth transition for just going to reversion；Cause necessarily passes through zero speed from reversion is just gone to, therefore revolving speed tends to
When zero, torque tends to be infinitely great.
Amplifying stage is the fixed drive ratio planetary transmission of standard, by speed change grade export from positive to negative
Smaller no-load voltage ratio is suitably amplified as needed, in this way, can pass through different amplifying stage no-load voltage ratios or different input speeds
It is combined into arbitrary speed adjustable range.For example, the principle prototype that our company successfully makes, amplifying stage no-load voltage ratio are 5.5 times, and input turns
Speed is 3000 revs/min, then output shaft output revolving speed is -1670 revs/min to+5200 revs/min stepless continuous variations.
The beneficial effects obtained by the present invention are as follows being:
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
Speed is to have a grade speed change；Although CVT speed changer can be realized variable speed, but it transmits torque by belt, exists
Frictional dissipation, low efficiency, transmitting torque is small, is not suitable for huge discharge automobile, and its speed adjustable range is limited, cannot achieve gamut
Stepless speed regulation.In order to possess a stepless transmission truly, global more than 100 Nian Laiyi of automobile vendor
It is directly all explored constantly, cost trillion, but even to this day without substantive progress.
Variable diameter gear stepless speed variator of the invention is pure gear-driven stepless transmission, has conventional transmission device same
The efficiency of sample, no gear gamut stepless speed regulation, revolving speed can be transitioned into reversion from continuously smooth is rotated forward, have non-neutral gear zero-turn
Speed output, while realizing that output torque levels off to infinity.Its (only 1/5 of automatic gearbox of vehicles volume) small in size, again
Measure light (be roughly equivalent to automatic gearbox of vehicles weight 1/10), simply (automatic gearbox of vehicles is various not multiple for control
Strays, electromagnetism, hydraulic control need to only adjust the angle of variable diameter control panel from the variation of 0-30 degree, can be realized gamut without
Grade speed regulation), its simple structure is made of one in which can be convenient with engine or motor.
Variable diameter gear stepless speed variator of the invention, the whole world is pioneering, advanced in the world.Its meaning is extremely great！Its revolving speed becomes
Torque tends to infinitely great characteristic when zero, will bring revolutionary industrial change！Its perfect continuous speed adjustment performance, will
Replace frequency converter, not only saves extensive fund, but also completely eliminate frequency converter to the serious harmonic pollution of power grid, fundamentally
Solve the global harmonic pollution problems of puzzlement.With on automobile, the performance of automobile will generate qualitative leap, and automobile starts
Machine no longer adds and subtracts throttle, and engine always works on optimized rotating speed, thus significantly energy saving；Due to continuous speed adjustment
Characteristic, so that the kinetic energy recycling in automobile downhill or slowing-down brake becomes simple and conveniently, this measure more can be saved significantly
Save the energy.
Be mounted with the automobile of variable diameter gear stepless speed variator, can be it is such, engine speed without adjustment, with fixation
Optimum speed operation；Cancel gas pedal, is changed to the no-load voltage ratio of speed control pedal control speed changer；Cancel clutch, cancel
Fluid torque-converter cancels complicated gear box hydraulic control system and electronic control system, can also because engine determines revolving speed operation
With partial cancellation or the electric spray control system of simplified engine.
Using such stepless transmission, the manipulation of vehicle becomes simply, only needs a speed control pedal i.e. controllable
