Summary of the invention
A kind of method for running belt drive unit according to the invention, and it is a kind of for executing this method
The feature with independent claims computing unit and computer program.Advantageous structural scheme be dependent claims with
And the content of following description.
The present invention provides a kind of possible schemes, for can reliably identify and compensate in belt drive unit
Belt trackslipping or skidding, and be used to can effectively and loss run the belt drive unit less.In this hair
It has been determined that the belt revolutional slip of standard, the belt revolutional slip of the standard are a kind of evaluation amounts in bright range, being used to can
By ground, identification the undesirable of belt trackslips or skids.
The belt pulley of driving and driven belt pulley transmission torque are attached by the belt of belt drive unit.?
It has been determined that the total of belt turns according to the revolution of the revolution of the belt pulley of driving and driven belt pulley in the range of this method
Rate.Total revolutional slip specifically describe belt in the current revolution of belt pulley, that is currently from driving
Belt pulley to driven belt pulley transmission torque when the total revolutional slip of reality.
Total revolutional slip particularly considers whole component parts of belt revolutional slip, especially not only allows for being based on
The abrasive action of belt, aging and with old belt revolutional slip, and consider through current environmental condition, is for example current
Temperature or belt pulley revolution belt revolutional slip.In addition, total revolutional slip particularly has also contemplated so-called extension slip
Rate extends revolutional slip in other words, and the extension revolutional slip extends special structure of the revolutional slip due to belt drive unit in other words
And the special fact is existing always.The elongation revolutional slip is attributed to the elasticity of belt.Due to surrounding belt disc spins
When act on the different power on belt, lead to occur relative motion between belt and belt pulley, this be referred to as extend slip
Rate.But the extension revolutional slip does not have shadow for the transmission of torque or the ability for belt for power-or transmission torque
It rings.
The elongation revolutional slip that belt is determined in the range of this method, in particular according to the theoretical model of belt drive unit
Or it is determined according to the particular magnitude of belt drive unit.It is particularly total by what is determined by means of theoretical model to extend revolutional slip
Revolutional slip is modeled.The difference of determining total revolutional slip and elongation revolutional slip is confirmed as the revolutional slip of the standard of belt.Institute
Total revolutional slip is stated to determine from the revolution of described two belt pulleys and diameter in line with the purpose in the range of this method, conversely,
The elasticity modulus of other magnitudes of physical quantity of belt drive unit, such as belt can also influence to extend the determination of revolutional slip.
The belt revolutional slip of standard describes the component part of revolutional slip, these component parts are not existing always, spies
It is not abrasive action based on belt, aging and with old and belt revolutional slip based on current environmental condition.Therefore it can borrow
The belt revolutional slip for helping the standard particularly securely identifies that the undesirable of belt trackslips or skid.
For this purpose, it is compared by the belt revolutional slip of the standard with threshold value, particularly with reliable maximum value.
Particularly, trackslipping or skidding for belt is specified up to or over the threshold value.If the belt revolutional slip of the standard reaches
The threshold value is arrived, then reducing the torque capacity or torque upper limit of the belt pulley of driving, Zhi Daosuo in the range of this method
The belt revolutional slip for stating standard no longer reaches the threshold value.
Particularly, which is turning for the torque for being transferred on driven belt pulley from the belt pulley of driving
Moment pole limit, which is established in systems, and the torque limit cannot be exceeded in operation.Particularly, described
Torque capacity is gradually reduced with previously given, such as 5Nm torque value always, until the standard belt revolutional slip no longer
Reach the threshold value.Therefore, in the skidding for recognizing belt, the maximum allowable torque for the belt pulley of driving is found newly
, no longer there is the skidding of belt in the case where the value in value.Next this maximum torque value being found is used as new turn
Moment pole limit, to avoid the skidding in future.
So, if although do not reach effective torque limit so far, for example, due to belt continue to develop it is old
Change-or wear phenomenon and for example there is the skidding of belt, then just automatically determining new effective turn by the method
Moment pole limit.Therefore by the method can in view of abrasive action, aging, with old and current environmental condition the case where
Under, and not over existing elongation revolutional slip causes distortion always, it can be realized belt drive unit
Effectively operation and effective transmission torque.
According to a kind of particularly preferred embodiment, if meeting a kind of condition after reducing torque capacity, just
The torque capacity is increased again.When especially no longer there is the skidding of belt during previously given time interval, institute
Condition is stated particularly to be satisfied.In this case, it is had checked in line with the purpose by increasing torque capacity: whether can be to turn
Square finds a kind of more accurate higher limit, and belt can non-skidly transmission torque until the limit.
Herein particularly, the torque capacity is stepped up with previously given, such as 3Nm torque value, described preparatory
Given torque value is less than the torque value reduced before the torque capacity in line with the purpose.Therefore it can be realized and recognizing skin
Band relatively quickly reduces torque capacity when skidding, to realize quickly attaching as far as possible for belt.Then by torque capacity
Smaller torque value is increased, the torque of the maximum possible under the conditions present of belt drive unit can be accurately soundd out
The limit, belt do not skid until the limit.
Advantageously, the torque capacity increases always again, until the belt revolutional slip of standard is located at around threshold value in advance
In given region.Particularly, the torque transmission of the region description maximum possible of belt, the torque transmission the case where
Under, belt is also attached on belt pulley and does not skid.
According to a kind of preferred embodiment, if the torque of the belt pulley of driving is when previously given, such as 1s
Between interim, under torque capacity in the previously given region of such as 3Nm, and if standard belt revolutional slip
Do not reach threshold value during previously given time interval, then just meeting previously given condition.In line with the purpose, such as
For fruit during previously given time interval, there is not the skidding of belt close to current torque capacity and herein in torque,
So just meet the condition.
Preferably, total revolutional slip S of beltgesAccording to the circumferential speed v of the belt pulley of drivingtWith driven belt pulley
Circumferential speed vgDifference determine.Total revolutional slip SgesIt is determined in line with the purpose according to formula below:
。
Because circumferential speed can also pass through the revolution n of belt pulleyt、ngAnd diameter dt、dgIt indicates, so described total
Revolutional slip SgesIt can also determine as follows:
。
There is speed loss by extending revolutional slip, which appears in the belt that fast driving is rotated than belt
It between disk and the driven belt pulley slower than belt rotation, and is the circumferential speed about belt pulley.Driven belt
The circumferential speed v of diskgIt is less than the circumferential speed v of the belt pulley of driving hereint。
As already explained, total revolutional slip is both influenced by belt slippage (being transmitted based on high torque), and
It is influenced as following illustrate by elongation revolutional slip, the elongation revolutional slip is in elastic belt in transmission torque
Always existing.
When around belt disc spins, belt receives different power.The slave quilt of transmission reversion section, that is belt
The section that the belt pulley of the belt pulley of driving to driving is run, receives so-called transmission reversion section power F hereinZ.Idle running reversion
Section, the section that is belt pulley from driving of belt is run to driven belt pulley, receive so-called dally back
Row section power FL.The transmission reversion section power FZGreater than the idle running reversion section power FL, and the transmission reversion section is to be higher than idle running
The speed of reversion section is run.When belt is around driven belt disc spins, therefore belt-or reversion Duan Li are being exported
So-called peripheral force FUIn the case where from transmission reversion section power FZDrop to idle running reversion section power FL.Conversely, reversion Duan Li is in skin
From idle running reversion section power F when band is around the belt disc spins of drivingLIncrease peripheral force FUReach transmission reversion section power FZ.It is different
Reversion Duan Li different elongations is caused due to the elasticity of belt.
Therefore the belt extends herein when around driven belt disc spins.Corresponding extended belt section can
It is elongated with saying by driven belt pulley, that is to say, that lead to occur opposite fortune between belt and driven belt pulley
Dynamic or sliding.Conversely, from transmission reversion section and therefore the belt section that maximally extends in the disk around driving
It is tightened again when rotation due to the reversion section power of reduction.Belt is and therefore same it may be said that shrink on the belt pulley of driving
Sample leads to relative motion or sliding.Extension-or contraction process of the belt on the belt pulley, which are referred to as, extends revolutional slip,
The extension-or contraction process lead to the relative motion between belt and corresponding belt pulley.
The peripheral force FUDifference (F depending on reversion Duan LiU=FZ-FL).The reversion Duan Li is equally applicable to two
Belt pulley, so that the peripheral force to work at two belt pulleys is also identical.Different reversion Duan Li only result in skin
Band elongation different at two belt pulleys, however the reversion Duan Li to work is but transmitted in belt with same size.Extend
Therefore revolutional slip does not influence peripheral force, and therefore do not influence torque variation.
As already explained, elongation revolutional slip advantageously according to the theoretical model of belt drive unit or according to
The magnitude of physical quantity of belt drive unit determines.Preferably, revolutional slip S is extendedDIt is following to determine:
。
MtIt is the torque of the belt pulley of driving herein, and k is the personalizing parameters for special belt drive unit,
The parameter can for example be determined by analysis measured value.
Total revolutional slip and extension revolutional slip can be by means of the revolution n of the belt pulley of drivingtParticularly as with
Under be equally linked together:
。
If it is known that factor k, then can be in line with the purpose by means of the relationship to elongation revolutional slip modeling.
Just as explained above, parameter k can be determined by analysis and utilization measured value, especially by for driving
The power of belt pulley and the measured value of total revolutional slip determine.Total revolutional slip can also indicate as follows:
。
Wherein, ωtIt is the angular speed of the belt pulley of driving, and Pt=Mt ωtIt is the power of the belt pulley of driving.Pass through
Unlocking the relationship can following expression parameter k:
。
Such as personalization for special belt drive unit can be determined in the manufacturing process of belt drive unit
Parameter.But suitable measured zone should be used in this respect.Particularly, simultaneously in case of the power transmission that can be measured
And there is no torque variations suddenly, then measured zone is exactly suitable.Because of PtIn the denominator, the formula is for smaller
PtValue can be inaccurate.
Just torque capacity is subtracted if the belt revolutional slip of standard has reached threshold value according to preferred embodiment
It is small to arrive following values, that is, the value corresponding to torque of the belt pulley during previously given time interval of driving average value with
The difference of torque value that can be previously given.Such as can be herein using the average value of the torque of last 100ms, and pass through in this way
Often reduce torque value, for example reduce 5Nm, until the belt revolutional slip of standard no longer reaches the threshold value.Such as it can be directed to
The PT1- link that the determination of average of torque uses torque to adjust.
According to a kind of particularly preferred embodiment, belt makes the belt pulley of the motor of motor vehicle and the belt pulley of internal combustion engine
Transmission torque it is connected.Be herein according to motor motor type or generator-type run or the belt pulley of motor or
The belt pulley of person's internal combustion engine is used as the belt pulley of driving.It can also be by means of working as even if in the belt for having abrasion with old sum
