Description
Technical field
The present embodiments relate to vehicle speed variation technical fields, and in particular to a kind of buncher.
Background technique
CVT (Continuously Variable Transmission) technology, that is, Variable Speed Technology, it is using transmission
The driven wheel that band and working diameter can be changed matches to transmit power, the continuous change of transmission ratio may be implemented, to obtain
The best match of power train and engine operating condition.Common stepless transmission has hydraulic mechanical type stepless transmission and metal band type
Stepless transmission (VDT-CVT), it is more and more using the vehicle of CVT on domestic market.
Three kinds of liquid transmission, Electric Drive and machine driving modes can be used.Liquid transmission is divided into two classes: one kind is hydraulic
Formula, mainly by pump and motor form or by valve and pump group at variable speed drive, be suitable for middle low power and be driven.It is another
Class is hydraulic type, carries out gear using fluid coupling or fluid moment, is suitable for high-power (hundreds to thousands kilowatt).Liquid
Body transmission is mainly characterized by: speed adjustable range is big, and absorbable to impact and prevent from overloading, transmission efficiency is higher, and the service life is long, is easy to real
Now automate: the accuracy of manufacture requires high, and price is more expensive, and output characteristics is permanent torque, and sliding ratio is larger, and when operating is easy to happen leakage
Oil.Electric Drive is essentially divided into three classes: one kind is electromagnetism slidingtype, it be installed in asynchronous motor an electromagnetic slip from
Clutch is adjusted the speed by changing its exciting current, this belongs to a kind of more backward mode of speed regulation.Its characteristic structure is simple, at
This low, convenient operating maintenance: sliding is maximum, low efficiency, and fever is serious, is not suitable for permanent load operating, therefore is normally only used for small
Power transmission.Two classes are DC motor types, realize speed regulation by changing magnetic flux or changing armature voltage.Its main feature is that speed regulation model
It encloses greatly, precision is also higher, but the device is complicated, and it is at high cost, it is difficult in maintenance, it is generally used for medium power range (tens to several hundred thousand
Watt), gradually substituted by ac motor formula.Three classes are ac motor formulas, are adjusted by pole-changing, pressure regulation and frequency conversion
Speed.The most persons of practical application are frequency control, i.e., obtain luffing power supply using an amplitude transformer, then drive motor speed change.Its
Feature is good speed adjustment features, range is big, efficiency is higher, be can be automatically controled, small in size, suitable power range is wide: mechanical property exists
Reduction of speed section permanent torque, low efficiency and operating is not stable enough when low speed, price is higher, and maintenance needs professional.In recent years, frequency conversion
Device is rapidly developed as a kind of advanced, excellent speed change gear, and certain impact is produced to mechanical stepless transmission.Machinery passes
Dynamic feature is mainly: stabilization of speed, sliding ratio is small, reliable operation, has invariable power mechanical property, and transmission efficiency is higher, and
And structure is simple, easy to maintenance, price is relatively cheap；But parts machining and lubricating requirement are higher, and bearing capacity is lower, anti-mistake
Carry and impact resistance it is poor, therefore in being generally suitable for, small-power transmission.
Buncher is due to clearly not specific gear, similar automatic gear-box in operation, but the variation of speed ratio
But it is different from the process of trip stopping of automatic gear-box, but it is continuous, therefore power transmission is lasting and smooth.Have V-type rubber belt type,
A variety of constructions such as metal band type, multi-disc type, steel-ball type, idler wheel rotating disc type are mostly passed using the idler wheel of metal tape and variable radius
Defeated power.Through the variation of driving roller and passive roller radius, reach the variation of gear ratio.The theoretically this kind of drive
Efficiency is very high, but must be set up in the case where the power that energy load is transmitted.Due to being using between steel band and idler wheel
Frictional force transmits power, so the working condition of steel band and idler wheel is very harsh.In order to effectively transmit power, steel band and idler wheel it
Between do not allow to skid, and originally generate thermal energy it is very much, if skid again will probably make internal works burn or
Serious consume.And in order to increase stiction, most direct mode is exactly the pressure increased between steel band and idler wheel.But frictional force
It increases, the consume of power transmission also will increase, and virtually still increase oil consumption.And the intensity of steel band is also a big weight
Point.Although so CVT gearbox have the advantages that it is comfortable, high-efficient and energy saving etc..Disadvantage be exactly current general CVT gearbox not
It can bear biggish torsion.Not so it seeks to be compensated with higher oil consumption.
The difference of stepless transmission and step type is that the not intermittent point of its gear ratio is a series of continuous
Value, for example can change to always 0.85 from 3.455.CVT structure is simpler than conventional transmissions, and volume is smaller, it is both without hand
Numerous gear pairs of dynamic speed changer, also without the planetary gear set of automatic transmission complexity, it is mainly by driven wheel and metal
Bring the stepless variation for realizing speed ratio.Its principle is that several groups of gears not of uniform size as common gearbox have under manipulation
Dividing has conjunction, different speed ratios is formed, as the pedal of bicycle rotates at different rates through big small trochal disc and chain-driving wheel.
Since the thrust that different dynamics generates each group gear is not of uniform size, the revolving speed for causing gearbox to export also changes therewith, from
And realize the low rotation regardless of class.
Meanwhile the stepless transmission of V-type rubber belt type, metal band type construction is becoming maximum revolving speed and is becoming minimum speed
When the power that transmits can become smaller, because of cornerite very little when transmission belt and the active wheel of minor radius contact, be easy to skid at this time.
In addition, the torque of the stepless transmission transmitting of V-type rubber belt type, metal band type construction is small, is becoming maximum revolving speed and becoming most
The power transmitted when small revolving speed can become smaller, and due to cornerite very little when the active wheel of transmission belt and minor radius contacts, hold
Slipping phenomenon easily occurs.
