Abstract
The present invention relates to for examining and/or the device of calibration test platform, particularly for the device of motor vehicle, described device includes measuring device, which is configured to the tangential force on the periphery for measuring the test idler wheel acted on testing stand.
Description
Technical field
The present invention relates to for detecting and/or the device and method of calibration test platform, particularly for the device of motor vehicle
And method.
Background technique
In the testing stand for motor vehicle, such as on rolling rig, measurement accelerate and brake, namely negative plus
The power on the wheel supporting face of tire is acted under speed conditions.
The measurement of power based on torque is realized herein.It stands on test idler wheel at this moment vehicle wheels, test rolling
Wheel passes through driving axis connection with drive motor.Drive motor is swingingly supported.Supporting construction is force snesor.If motor vehicle
Wheel accelerates or braking, and the power formed herein will pass through force transmission area domain and be transmitted on test idler wheel.This power passes through bearing,
That is force snesor, to measure.The measurement of power is realized indirectly by torque measurement.
First bar reaches the region that the power in roller surface imports from the midpoint of test idler wheel.Second bar from test idler wheel
Midpoint extend to bearing.Power at bearing is obtained by the ratio of the first bar and the second bar.
In order to detect and/or calibration test platform, reference load is imported directly at force snesor.This is put by mounted thereto
It sets ponderable power bar to realize, or by being equipped with the power bar realization with reference to force snesor in its force flow.
The shortcomings that herein is that there is no incidentally consider the two actual mechanical shafts herein.These mechanical shafts are calculated one
It is secondary and received as what is provided.
Furthermore when installing linkage, another lever ratio is formd, which is different from the first bar and the second bar
Ratio.
Therefore the test chain from force snesor to measurement display screen has only been calibrated with such calibration.However if
The ratio of one bar and the second bar changes, then it is not taken into account.But the variation of lever ratio often occurs, such as
If test idler wheel is worn when examining by mechanical load at any time.Reduce in the diameter at this moment testing idler wheel, thus first
The ratio of bar and the second bar can also change.
Furthermore detection bar and referential weight have the disadvantage that all weight can be by terrestrial gravitation.Therefore herein,
The gravity value of part was originally must be known, and is considered.Furthermore it also will receive with the detection bar that referential weight loads
The many other influences formed when load.Therefore each load can generate the deformation of bar, can generate a change lever ratio again
Example result and must be corrected again.
Another disadvantage is present in, and in order to calibrate, testing stand must be opened and power bar must be mounted.
It is known that in detection axis setting to test idler wheel.The wheel of braking performance test axis and torque is supported to examine
It surveys at axis and is measured in the form of torque measurement.Then compare the power of importing and the power shown on rolling rig.
Although testing stand need not be opened, but it is that this detection method is also based on torque and will receive same mistake
Difference.
The change of the wheel diameter of detection axis also results in the variation of lever ratio herein.Furthermore there is also cause
Measure many other factors distorted.
In accordance with the regulation of law, it is necessary to the regularly calibration test platform under high-precision.However, for example due to testing idler wheel
, will not enter together measurement in abrasion, such high-precision is not achieved using detection device so far.
Summary of the invention
Therefore the task of the present invention is provided for detecting and/or the device and method of calibration test platform, with simple
And the suitable mode of cost allows to accurately detect or calibrate.
The solution of this task is realized by the object or method of independent claims.
According to the present invention, this is used to detect and/or the device of calibration test platform includes measuring device, measuring device construction
At for measuring the tangential force on the test idler wheel periphery for acting on testing stand.
Testing stand can for example be related to the testing stand for example for motor vehicle.However in principle, arbitrary testing stand is all
It is conceivable, in particular for the testing stand of rolling bearing, such as in paper-making industry and/or textile industry.
According to the present invention, the tangential force on the periphery of measurement test idler wheel.Because tangential force is directly measured, need not
Indirect power measurement is realized by inaccurate torque sensor etc..The abrasion of idler wheel is tested also due to direct measurement is to inspection
Survey or calibrate no negative impact.
Therefore, detection device according to the present invention make by simple and cost suitably in a manner of accurately detect or school
Quasi- testing stand is possibly realized.
The remodeling of invention also can be from dependent claims, specification and attached drawing.
According to embodiment, measuring device is configured to for detecting and/or the measurement based on torque of calibration test platform.In
For most of testing stand of motor vehicle, measurement is realized based on torque.Due to the influence having been described, such measurement
As the process of time is still with error.Importantly, to detect or calibrate just these measurements based on torque.
However in traditional detection device, detection and/or calibration are similarly based on torque, thus invisible negative shadow
It rings.It therefore is being by chance on the testing stand by means of being worked based on torque measurement, in detection or calibration test platform luck
It is advantageous with the alternative measuring device for being not based on torque measurement.Measurement acts on the tangential force on test idler wheel periphery herein
It is advantageous, because many negative impacts are detected.
According to another embodiment, measuring device is configured for the entire test chain of detection and/or calibration test platform.
It is only carried out from force snesor to measurement display screen in traditional detection device alignment, and according to the present invention, it is entire to test chain quilt
Calibration.Legal provisions are satisfied in this way.
Particularly in view of the mechanical wear and/or power of test idler wheel import the change of bar.Therefore in the long period
After operating, when test idler wheel has been worn, calibration is also accurately realized always.Due to this influence, the survey based on torque
Therefore deviation in amount is noted and is considered accordingly.
According to another embodiment, the measuring unit of measuring device is configured to tension measurement device and/or pressure sensor.
In particular, measuring unit may include at least one foil gauge.Also the arrangement being made of multiple foil gauges can be set, for example, half
Bridge or full-bridge.
Such as tension measurement device can be related to traditional tension scale.After test idler wheel is driven, tension measurement device can
To be especially put into use.
Such as pressure sensor can when test idler wheel work as brake when be put into using measuring unit whether structure
It makes as tension measurement device or is configured to pressure sensor, depend on the positioning of measuring unit eventually.
According to another embodiment, the measuring unit of measuring device directly measures the tangential force to be measured.Thus it minimizes
Many error sources, because tangential force is not measured the intermediate connection of other component directly and in particular.
According to another embodiment setting belt and fixed device.The examination of testing stand can be fixed or be fixed on to the fixation device
It tests at idler wheel.Herein, test idler wheel must have the fixed solution for belt, and the fixed solution is on traditional testing stand
There is not yet.For correspondingly reforming test platform, it is therefore necessary to the test idler wheel that adjustment or replacement are come into operation so far.However
At new test idler wheel, the test idler wheel with corresponding fixed solution can be equally set.
Therefore the end of belt passes through fixed device, such as be bolted, and is fixed on test idler wheel.The other end of belt
It is connect with the measuring unit of measuring device or attachable.
Belt is around test idler wheel, preferably about at least 180 °, 200 °, 220 °, 250 °, 270 °, 300 °, 330 °,
350 ° or 360 °.
Especially belt is moved towards along test idler wheel periphery and is tangentially guided to measuring unit.Here, belt leaves
Test idler wheel position on measurement do not influence because leave always tangentially realize and pulling force be always converted to rotate.
According to another embodiment, locking device is provided with to test the driver of idler wheel.So for example test idler wheel
Rotor can be locked.
Power can be coupled on test idler wheel circumference.Here, for example by means of linear actuator or screw driver
Clamping device, especially hydraulic system, to test idler wheel applied force.Then the tangential force in roller surface is accurately tried with utilization
Platform power obtained is tested to be consistent.In this method, the power of importing is consistent with power to be shown.
Belt, which is centered around, to be drawn on test idler wheel and surrounds the test idler wheel, especially at least surrounds 180 °.When an end
When being fixed on test idler wheel, another end is connected with measuring unit and it is connected with force generating apparatus again.
Driver for testing idler wheel is locked up in inside, therefore tests idler wheel in the case where applying force on belt
It not can rotate.
If drawstring is sub, tangential force just has been imported in roller surface, on the circumference that idler wheel works.Because of test rolling
The driver of wheel is braked, this power is directly delivered to measuring unit.
If testing stand also necessarily shows this numerical value, that is to say, that with the first bar such as with 500N in belt pull-up
It is unrelated with the ratio of the second bar.Therefore, the roller diameter for considering variation is also accompanied by calibration.
In this way, can be accurately adjusted or calibrate the entire test chain from roller surface to measurement display screen.
This detection device is configured in cost very suitable.
According to another embodiment, the measuring unit of measuring device measures the tangential force to be measured indirectly.Therefore it measures
Unit is not directly in and tests in the connection of idler wheel.Such as measurement sliding block can be lain on test idler wheel.Therefore for example not
With on test idler wheel, fixed solution is set.Detection and/or calibration can be realized in such a way: without being switched on and, if there is
If necessary, reforming test platform.
According to another embodiment, setting is used for the contact device of the test idler wheel of contact test platform, wherein measuring unit
It is connect with contact device either attachable.Tangential force is also directly measured herein, that is tangential force is not to calculate first
Or it is determined and the measurement based on torque.But tangential force is measured indirectly by contacting device.Tangential force passes through contact dress
It sets and is directed to measuring unit.Measuring unit can be preferably directly connected to contact device.
According to another embodiment, contacting device includes the contact with for continuous band or plane of at least one continuous band
At least two deflection rollers of plate.Sliding block is also referred to as measured by the device that deflection roller and continuous band form.Furthermore continuous band
There is this advantage: the vibration of complementation test platform.
The concept of this continuous band will broadly understand, and in addition to single wide belt, also include it is multiple it is narrow,
The belt being arranged side by side.The overall width of the width of belt or many belts can about be consistent with the tyre width of automobile.
Width can be especially calculated as between 100mm and 300mm, preferably between 150mm and 200mm.
The contact plate of plane primarily in this way as measurement sliding block play a role, wherein measurement range with
Continuous band is relatively limited.
Continuous band or contact plate especially can be structured as capableing of simple replacement, such as worn out continuous in order to replace
With perhaps worn out contact plate perhaps according to demand using the continuous band or contact plate for having another coefficient of friction.
Detection device is fixed to first on the frame of testing stand.Measurement sliding block or contact plate are placed to test idler wheel
On.Measurement sliding block or contact plate are preferably freely movable in the horizontal direction and are connected by measuring unit with frame
It connects.
Resistance can be generated in roller surface in braking.The resistance is then measured by measuring unit 1:1.It is testing
Horizontal force on idler wheel vertex meets tangential force.Abrasion on measurement sliding block or contact plate not will lead to measurement error.
Measured power is consistent with the tangential force acted on idler wheel circumference in measuring unit.On the contrary, the biography of testing stand
Sensor measures the power generated under the ratio comprising the first bar and the second bar.If lever ratio is, for example, 1:2, in roller surface
On 500N generate at the sensor of testing stand 250N effect.
It must be 500N when correctly showing in numerical value being provided on the sensor of testing stand or showing,
That is lever ratio must be taken into consideration.If lever ratio changes, because such as roller diameter is become smaller by abrasion, testing stand
Power on sensor can also change, and especially become smaller.
Existing with which error test unrelated in chain, this error can be directly seen because test idler wheel outside
The power imported on week is always by correct measurement.
Such detection device can be for example mounted on testing stand.Detection device, which also can be set, to be detected in trailer.
Such as device can be will test by hydraulic system and lain on the test idler wheel of testing stand.Always it measures tangential force rather than turns round
Square.
By having the detection trailer of device according to invention, for detecting and/or calibrating, which can be neatly
Use is put into different places.
According to another embodiment, the upside of the contact surface of device, especially continuous band is contacted, has raising being rubbed
Material and/or the structure for being enhanced friction.
Such as rubber material and/or small burl or rib can be set, rub for improving and preferably generate
Force closure.Power transmitting herein will not by trackslip effect and it is impacted.
According to another embodiment contact device be arranged at arm, the upper-arm circumference around relative to a certain contact surface at least substantially
The axis of oscillation of capwise is swingably supported.
The arm at least surrounds that axis of oscillation is subtle to be swingably supported.It measures sliding block or contact plate therefore can be certainly
It mutually orients and aligns with the orientation of test idler wheel.Thus avoid cross force.Thus it is being examined in the apex of test idler wheel
It surveys or also maintains the position being expected to during calibrating.
According to another embodiment, provided with pressure sensor, angular transducer, the brake apparatus for contacting device,

Fig. 1 shows that the testing stand 10 with test idler wheel 12, the test idler wheel 12 surround on the axis for being configured to arm 14
Rotation axis D is rotationally supported.Multiple bearings 16 are provided with for axis 14.Axis 14 can be by being also used as brake
Driver 18 is driven.
Show that the wheel 20 of motor vehicle, the wheel 20 transfer force on force transmission area domain 22 on test idler wheel 12
Test idler wheel.
Driver 18 is swingingly supported together with axis 14.Sensor 24 is herein used as supporting.Pass through at sensor 24
Torque measurement and determine power.If wheel 20 accelerates or braking, the power formed herein are just transmitted to via force transmission area domain 22
It tests on idler wheel 12.Power is measured by the sensor 24.
Sensor 24 is connect with measuring amplifier 26, which is connected with Measurement and Data Processing equipment 28 again.
Measurement and Data Processing equipment 28 has interface 30, such as ASA interface, and measurement display screen 32.
Measuring amplifier 26 and Measurement and Data Processing equipment 28 are a part of the test chain 34 of electricity.
Measurement based on torque needs the ratio of the first bar L1 and the second bar L2.Rotation of the first bar L1 from test idler wheel 12
The 22. second bar L2 of force transmission area domain that axis D is extended in roller surface extends to bearing from the rotation axis D of test idler wheel 12
24.Power at bearing 24 is obtained from there through the ratio of L1 and L2.
Up to now, reference load is imported directly at sensor 24 in order to calibrate.Do not consider incidentally herein mechanical in reality
Bar L1 and L2.These mechanical bars are calculated only once and are received as what is provided.Therefore what is only calibrated is from sensor
The test chain 34 of 24 electricity.In contrast, the ratio variation of the first bar L1 and the second bar L2 is not considered.However actually this compares
Example continually changes, because test idler wheel 12 is worn with the time.
Fig. 2 is shown for examining and/or the device of calibration test platform 10, wherein directly measuring the tangential force F to be measured.
Belt 36 end pass through fixed device 38 with test idler wheel 12 and connect and at least partly wrapping test idler wheel
12。
Belt 36 is connected in another end with the measuring unit 40 for the measuring device 42 for being configured to tension measurement device.
Measuring device 42 also includes force generating apparatus 44.
Power is coupled on the circumference of test idler wheel 12 first.Here, by means of force generating apparatus 44, for example, line motor or
The clamping device of person's screw driver, especially hydraulic system, to test 12 applied force of idler wheel.Then in the tangential force of roller surface
F is accurately consistent with using the power obtained of testing stand 10.In this method, the power of importing is consistent with power to be shown.
Driver 18 for testing idler wheel 12 is locked up in inside, therefore tests idler wheel 12 on applying force to belt 36
In the case where not can rotate.
If drawstring 36, tangential force just has been imported in roller surface, on the circumference that test idler wheel 12 works.Cause
It is locked up to test the driver 18 of idler wheel 12, this tangential force is directly delivered to measuring unit 40.
For example, being pulled up with 500N in belt 36, the sensor 24 of testing stand 10 also necessarily shows this numerical value, that is,
It says unrelated with the ratio of the first bar L1 and the second bar L2.Therefore, the roller diameter for considering variation is also accompanied by calibration.
In this way, can be accurately adjusted or calibrate the entire test chain from roller surface to measurement display screen 32.
Fig. 3 is shown for examining and/or the another embodiment of the device of calibration test platform 10.Herein, tangentially
Power F is measured indirectly by the contact device for being configured to measurement sliding block 46.
Measuring sliding block 46 includes two deflection rollers 48 and a continuous band 50 arranged around deflection roller 48.Measurement is slided
Block 46 is connected with measuring unit 40, however in addition to this unfetteredly horizontal movable in arm 14.
Arm 14 is swingably supported in test bed framework 52 around axis of oscillation S.Thus measurement sliding block 46 flushes ground always
Orientation.
If continuous band 50 is braked, resistance just is generated on the surface of test idler wheel 12.Then pass through measuring unit 40
The resistance is measured with 1:1.By the measurement of tangential force F, abrasion does not lead to measurement error.The power measured in measuring unit 40
Meet with the tangential force F on idler wheel circumference.
The power that the measurement of sensor 24 of testing stand 10 is generated by bar L1 and bar L2.If ratio is, for example, 1:2, rolling
Such as 500N on wheel surface generates the effect of the 250N at sensor 24.
Such calibration measurement display screen 32, if so that there display 500N bar ratio L1 ratio L2 is for example, by roller diameter
Become smaller by abrasion and changed, the power at sensor 24 can also change.Herein, the error in test chain is noted, because
Correctly to measure at idler wheel outer diameter, imported power always.
It can use such as motor vehicle to generate power.In the case, measurement sliding block 46 be intended only as measurement auxiliary member connect
Enter between wheel 20 and test idler wheel 12.Alternatively, however, measurement sliding block 46 for example also can have driver.
Instead of the continuous band 50 rotatably arranged around deflection roller 48, measurement sliding block 46 also can be configured to immovable
, that is continuous band 50 is not rotated and cannot be rolled.
Herein, measuring sliding block 46 or arm 14 can be pressed on test idler wheel 12.Test idler wheel 12 passes through survey herein
Amount sliding block 46 is stuck.If starting driver 18, such as electric motor, then driver is due to being stuck without being able to rotate.
So just measure the parking torque of driver 18.However this measurement can only carry out the short time, because otherwise this measurement will lead to
The overheat of driver 18.
If people for example manipulate driver 18 by soft start equipment, such power can be generated with slowly rising.Such as
The experiment curv that this generation slowly rises is feasible.It can detecte measurement range by this mode.
Alternatively, such as contact plate can also be used instead of measuring sliding block 46.Contact plate can be with for example resisting spring capable
Enter retainer.The time that the rotation test idler wheel 12 of driver 18 is grown so, until reaching retainer.For example, in the speed of 5km/h
It, can be in about 1.3s against the contact plate of retainer driving 2m long under degree.
Fig. 4 shows the embodiment for being provided with extra means and sensor.
Two test idler wheels 12 can be connected with each other by chain 53.But also can only be arranged a test idler wheel 12 or
One rolling surface of person.
Arm 14 is fixed on a position of test bed framework 52.Arm 14 is swingable and is tiltably supported.
For example, angular transducer 54, the pressure sensor 56 for measuring pressure A can be set, slided for measuring measurement
The velocity sensor 58 of the speed of block 46, for measuring the brake apparatus 60 of sliding block 46, and/or for measuring test idler wheel 12
The especially driven detection idler wheel 62 of speed, especially idler wheel peripheral speed,.Inspection can be for example driven by servo motor
Survey idler wheel 62.
Thus the general test equipment for rolling rig 10 is produced.
It is possible thereby to generally promote the precision of such as test device.
Coefficient of friction can also be measured.For example, can be wet or dry in this continuous band 50.
Furthermore it can detecte the power of driver 18.Furthermore test speed can be measured.Also it can detecte monitoring of trackslipping to pass
Induction device.
Angular transducer 54 can measure test idler wheel 12 setting angle, if test idler wheel for example with dislocation and
It does not flush.It then can be in view of dislocation in measurement.
It, can also be with measuring speed and angle of oscillation as additional information.
Measure sliding block 46 may include different components in itself.Dependent on be measured, detection or calibration the parameter,
Driver 18 can active no-load rotation or checked.Measurement sliding block 46 can also be driven, no-load is dallied or checked.This
The outer parameter certain for measurement, can adjust accordingly pressure A.
Especially power measurement can be realized on direction of pull and/or pressure direction.For example, can be generated in no axial force
Tangential force is determined under state.
In addition, power measurement can be realized in the vertical direction.It can so determine pressure A.
One detection system can examine for example entire test chain, including driver comprising many sensor and device
Coefficient of friction on 18 power and roller surface.Detection system is shown as in this way for the general of rolling rig 10
Diagnostic system.
