Abstract

PURPOSE:To promote the accuracy of detection of puncture, by using load cells to find out the ground contact load upon the rubber tires of a vehicle, memorizing and processing the maximum load upon each wheel and the time of presence of the load and comparing the processed values with judgment references to detect the puncture. CONSTITUTION:Load cells 6R, 6L are provided between a track 4 for a vehicle 1 and tread boards 5R, 5L. When wheels 3A-3D pass the load cells 6R, 6L, the load of each wheel and the time of presence of the tires on the tread boards 5R, 5L are found out so that the maximum load values LA-LD of the wheels and the durations TA-TD of presence of the load are memorized. The values LB/ LA, LD/LC, TB/TA, TC/TD are then calculated. The calculated values are compared with set values KL, KT. For example, when the value LB/LA is larger than that KL and the value TB/TA is smaller that than KL, the tire 3A is regarded as punctured. The accuracy of detection of puncture is thus promoted.

In recent years, concrete track vehicles are being adopted in urban transportation systems instead of rail track vehicles from the viewpoint of ride comfort, vibration, noise, etc. These vehicles use wheels with rubber tires, but they are prone to punctures.
For safety reasons, it is necessary to detect this in advance.

The conventional puncture detection method detects the maximum load applied to a wheel when it passes over a tread placed at an appropriate location on the track, and calculates this ratio by comparing the maximum load values of the left and right wheels on the same shaft. A puncture was determined when the value was below a certain value. However, this method has the disadvantage that it cannot be detected unless the tire pressure is at a value close to zero, and the detection accuracy is also low.

不都合なことに、もし同一軸の左右輪が同時にパンクし
ている場合には、検出が不可能である。
Unfortunately, if the left and right tires on the same axis are punctured at the same time, detection is impossible.

Furthermore, the wheels of a single bogie truck have the disadvantage that when the -wheel is punctured, the load applied to the wheel diagonally opposite to the punctured wheel is reduced, resulting in false detection.

Therefore, it is an object of the present invention to eliminate the above-mentioned drawbacks and provide a new method for accurately detecting punctures.

In summary, the present invention is a method for detecting a tire puncture by detecting the ground load of a tire wheel installed on a truck using a load cell, and detecting an electrical signal corresponding to at least the maximum load of each wheel from the output of the load cell. At the same time,
This detection data is once stored in the storage means, the stored data is processed by the calculation means, and the result is processed based on predetermined criteria to detect a flat wheel. .

The vehicle 1 is equipped with a bogie 2.2 at the bottom, and the bogie 2 is supported on a track 4 by four wheels 8A, 8B, 3C, 8D. The ground contact portions of the wheels 8A, 8B, 8C, and 8D are all made of rubber tires. Wheels 3A and 3C, wheels 3B and 3

The ground loads of A, 3B, tire wheels 3C, i3D are converted into electrical quantities.

When the vehicle l moves in the direction of the arrow in the figure, coaxial wheels 3A,
13c rides on the footboards 5R and 5L, and the load is detected. When the wheels 9A, 3C come off the treads 5R, 5L, the wheels 3B, 3D then ride on the treads 5R, 5L, and the load is similarly detected. When detecting this load, the detection device can also detect the amount of time the wheel remains on the tread. In other words, when a negative wheel passes over the tread, the load cell monitors the time for which the load continues to output an electrical signal of 0 or more.

The first specific example is a puncture detection method that compares the peak value of the ground load of a wheel and the width of time it passes over a load cell between front and rear wheels of the same truck, and identifies a punctured wheel based on predetermined criteria. This method takes advantage of the fact that a flat wheel stays on the tread for a long time.

, TD/TC is calculated. Then, a comparison calculation is made with a predetermined value kLl #kT set in advance (in the storage means), and a wheel with a low level and a large time width is determined to be punctured. That is, if LB TB ->kLl and -<kT LA TA, the right front wheel 8A is determined to be punctured. If this is reversed (both inequality signs are in opposite directions), the right rear wheel 8B is punctured.

If so, the left front wheel 8C is determined to be punctured, and if the opposite is the case, the left rear wheel 8D is determined to be punctured. Of course, if these conditions are not met, it is determined that there is no flat tire.

Note that the numerator and denominator of the load peak value ratio and time width ratio may be reversed. Accordingly, a predetermined value kLl'
kT changes. Alternatively, the conditions for the comparison operation to hold may be reversed. In short, the load peak value ratio and the time width ratio of the front and rear wheels are compared with predetermined values, and based on the results, a determination is made to identify the presence or absence of a puncture and the banked wheel.

Next, a second embodiment will be explained. This example is a measure to take when the left and right wheels are punctured at the same time, and the arithmetic mean value of the peak load values applied to the wheels of the same bogie is compared with the peak load value of each wheel, and this ratio is below a predetermined value. This method determines that there is a flat tire. In other words, the peak value average a (-value ratio LA/a, LB/a,
LC/a, LD/a i: A wheel that is equal to or less than a predetermined value kL2 is determined to be punctured. However, when taking the ratio with the average value, if the numerator and denominator of the above ratio are reversed, the predetermined value is '/

The point is to make a judgment based on the comparison result between the arithmetic average value and the individual load data. According to this determination, it is now possible to detect when both left and right tires have punctures at the same time. Furthermore, it is clear that if this second embodiment and the first embodiment described above are implemented in combination, the bank detection accuracy will be further improved.

第3実施例はボギ一台車における対策である。The third embodiment is a measure for a single bogie.

That is, when one wheel of a bogie car has a puncture, the load applied to the wheel located diagonally to the puncture wheel decreases, and there is a possibility of erroneous detection. So, in this example,
When the peak value ratio of the loads applied to the left and right wheels is less than a predetermined value, the lower level side is determined to be the main bank, but when the peak value ratio of the diagonal wheel loads is less than the predetermined value, the diagonal axis peak value is low. This method determines that only the level side is punctured.

Referring to Fig. 2, the peak value ratio LA of the left and right wheel loads is
/LC, LB/LD (or LC/LA, LD/LB
) is less than a predetermined value kL3, the lower level side is determined to be a puncture, while the weighting conditions are the peak value ratio of diagonal wheel load LB/LC (also 'L< is LC/LB), LA/LD
(or LD/LA) is less than a predetermined value kL4, only the lower level side of the diagonal axis peak value is determined to be a puncture.

具体的に示すと、kL3= l 、 kL4=Kに選ぶ
Specifically, kL3=l and kL4=K are selected.

Then, if the condition D of LA(LC-LD(LB is fully K) is satisfied, it can be determined that the front right wheel 3A is punctured. Also, if LA(LC-LD(LB and A LD), then the right front wheel 3A is punctured. It is determined that the front right wheel 3A and the rear left wheel 3D are punctured.It is preferable that the value of K is determined and set by experiment.According to this method, in a single bogie, the wheel located diagonally to the punctured wheel One advantage is that false detection of punctures can be effectively prevented.It is clear that by combining this method with the first embodiment, the detection accuracy is significantly improved.
