Abstract
A wheel alignment method is applied on a rolling testboard of a rolling stock, and is used for measuring and adjusting the relative position of a wheel of a test car and a rail wheel. The wheel base and the distance of a test car are different, positions of the car wheel and the rail wheel are changed, and the testing performance of the car is distortionless only when the center line of the two wheels are superposed within a range allowable for the accuracy. Only a suspension wire with wire pendants at the two ends and a ruler are adopted by the method, and a rail wheel is marked with a center line, and the method includes the steps as follows: the distance position of the rail wheel of a testboard is adjusted in place before the testing car wheel falls on the rail wheel; then the rail wheel is rotated slowed, the center line of the rail wheel is enabled to be vertical to the horizontal reference field (or superposed on the suspension wire); the suspension wire provided with the wire pendants at the two ends is basically and symmetrically placed on a shaft neck above the rail wheel and facing to the test car wheel; the horizontal distances of the center line of the rail wheel to the suspension wire on the two sides are measured through the ruler; and finally, the car wheel above the rail wheel is moved as per the difference value of the horizontal distances, and the test car wheel cannot fall on the rail wheel until the difference value meets the accuracy requirement. The method successfully solves the centering problem between the car wheel and the rail wheel caused by different car wheel bases and distances of various test cars, and has the characteristics of simplicity and convenience for operation, high efficiency, accuracy and safety.
Description
Affiliated technical field
Patent of the present invention is a kind of rolling rig that is used for, adopt messenger wire and do not have special tooling detect wheel of vehicle whether with the method for rail wheel centering.Classic method or be to be observed through eyes by experienced testing crew judges that by rule of thumb verify through testing, if test findings is identical with the universal law of grasp, then need not adjust the test vehicle wheel position, vice versa again; Detect with special tooling, though easy to use, efficient is high, the special tooling requirements of making is high.This detection method has successfully solved the centering problem between the wheel of vehicle and rail wheel on the testing table, has easy and simple to handle, safety, characteristic of accurate.
Background technology
When vehicle makes an experiment on rolling rig, undistorted in order to ensure the experimental performance of vehicle, should satisfy the centering requirement of wheel of vehicle and rail wheel.This method lets the center line on the rail wheel vertical with level reference (or overlap with messenger wire) earlier when using; Be benchmark with the rail wheel center line again, measure the horizontal range of rail wheel center line, come moving track to take turns the positions of wheels of vehicle of top, satisfy accuracy requirement up to this difference according to the difference size of these two horizontal ranges to its both sides messenger wire with ruler.At present, method commonly used is to be observed through eyes by testing crew, judges by rule of thumb; Verify through testing again; If the universal law of test findings and grasp is coincide, then need not adjust the test vehicle wheel position, vice versa; So neither science is inconvenient again: the experience that, relies on testing crew; Two, can not accurately hold the size of regulated quantity; Three, adjust the positional precision of wheel of vehicle and rail wheel centering through test findings, not only time-consuming but also require great effort; Detect with special tooling, though easy to use, efficient is high, the special tooling requirements of making is high, relatively is suitable for the many situation of test number (TN).
Summary of the invention
In order to judge whether to want the position of rolling test wheel of vehicle and the size of amount of movement fast, accurately, easily; Patent of the present invention provides a kind of easy, convenient, measuring method accurately; It had both effectively overcome traditional shortcoming of judging by rule of thumb; Improve the efficient and the precision of the adjustment of test vehicle wheel position greatly, can effectively avoid making special tooling again, especially the not really frequent situation of adequacy test.
Patent of the present invention solves the technical scheme that its technical matters adopted: make center line on the rail wheel vertical with level reference (or overlap with messenger wire) earlier 1.; 2. be benchmark with the rail wheel center line again, measure the horizontal range of rail wheel center line to its both sides messenger wire with ruler; 3. come the positions of wheels of vehicle of moving track wheel top according to the difference size of these two horizontal ranges, satisfy accuracy requirement up to this difference.Method of application: before the test vehicle wheel does not drop on the rail wheel, earlier testing table rail wheel distance and position is adjusted to the right place; Secondly rotation track wheel slowly makes rail wheel center line vertical with level reference (or overlap with messenger wire); The messenger wire that then two ends band line is weighed down places on the right axle journal of rail wheel top test vehicle wheel basically symmetrically, measures the horizontal range of rail wheel center line to its both sides messenger wire with ruler; Come the positions of wheels of vehicle of moving track wheel top at last according to the difference size of these two horizontal ranges, satisfy accuracy requirement up to this difference and just the test vehicle wheel is dropped on the rail wheel.
The beneficial effect of patent of the present invention is: 1, improved work efficiency significantly: patent of the present invention can once be adjusted to the right place by the warranty test positions of wheels of vehicle; 2, easy to use, use simple to operate: frock specially, only with messenger wire and ruler; 3, improved the adjustment precision greatly: through measuring the horizontal range of rail wheel center line with ruler, and come the positions of wheels of vehicle of moving track wheel top according to the difference size of these two horizontal ranges to its both sides messenger wire.
With the variation of test vehicle wheelbase and spacing, the position of testing table rail wheel and test vehicle wheel all will change, and how both positions change the center line that all requires two wheels overlaps in the scope that precision allows.Test ninety-nine times out of a hundred all will be carried out this adjustment work, adopts this wheel to look for middle method can effectively overcome the shortcoming of classic method, improves the precision and the work efficiency of position adjustment greatly, can avoid making special tooling again.
Description of drawings
Accompanying drawing is the synoptic diagram of patent of the present invention.
In the accompanying drawing: 1. instruction carriage wheel, 2. instruction carriage axle journal, the 3. messenger wire that weighs down of two ends band line, 4. rail wheel.
Embodiment
Shown in accompanying drawing, the two ends band line of messenger wire 3 weighs down, and instruction carriage axle journal 2 is the parts on the axletree, and its machining precision is very high.
Embodiment: before test vehicle wheel 1 does not drop on the rail wheel 4, earlier the distance and position of testing table rail wheel 4 is adjusted to the right place; Secondly rotation track wheel 4 slowly makes rail wheel center line vertical with level reference (or overlap with messenger wire); The messenger wire 3 that then two ends band line is weighed down places on the right axle journal 2 of rail wheel top test vehicle wheel basically symmetrically; Measure horizontal range a and the b of rail wheel center line with ruler again to its both sides messenger wire; Come the position of the wheel of vehicle 1 of moving track wheel top at last according to the difference size of these two horizontal range a and b, satisfy accuracy requirement up to this difference and just test vehicle wheel 1 is dropped on the rail wheel 4.
