Abstract

The invention aims at providing an impact force measuring device of a driving tire which measures the impact force when the tire in driving meets hillock and is attacked, in particular ensuring a ration measuring data corresponding to the position of the hillock relative to the impact force applied to the driving tire.

Description

The impact force measuring apparatus of traveling tire
Technical field
The present invention relates to that tire in travelling runs into thrust and measure the impact force measuring apparatus of the traveling tire of its impact when being subjected to clashing into, particularly can guarantee with respect to the quantitative measurement data corresponding with the position of thrust for the impact that tire applied in travelling.
Background technology
As everyone knows, the tire in travelling often exists because of the outstanding thrust in road surface causes damaged danger, and accident frequently took place when present situation was actual travel.
As with experiment and the assay method of this tyre damage, be experimental technique and the device of being introduced in SAEJ1981 " the Road hazard impact test for wheel and tireassemblies " literary composition by widespread usage in indoor reproduction.This device is the device of estimating with respect to the resistance performance of outside tires impact, also is the evaluation method and device that the accident situation of reality is reproduced.
In addition, with respect to said method, consider that actual service condition by in the disclosed Republic of Korea of inventor publication 2006-0041329 number, discloses a kind of sidewall impact resistance power determinator of tire.
Two above-mentioned technology can wait according to the weight of thrust and brachium, distance of fall and calculate destruction kinetic energy, but are not the evaluation method of research bump kinetic energy under actual service conditions, only experimentize by relative comparative evaluation.
On the other hand, under situation as the additional and impetus determinator of the moving bump load of the tire tread portion of Republic of Korea's publication of having proposed by inventor 2005-0120262 number, because this device is the technology in the impact of indoor measurement rotating tire, thereby there is a following shortcoming, promptly under the situation of tire actual installation, because flare (Camber) and prenex (Toein) etc. are former thereby produce certain deviation.
Summary of the invention
Therefore, the object of the invention is to provide a kind of impact force measuring apparatus of traveling tire, it can improve above-mentioned problem points in the past, when measuring the tire impact, can measure quantitatively the impact that thrust transmitted in being travelled by the actual tire as benchmark.
In order to achieve the above object, the present invention is a kind of like this impact force measuring apparatus of traveling tire, it has data reception portion, for the tire that travels on the road surface is applied impact, projection is installed on the inside of mounting groove, and its part is outstanding to the road surface, and the impact that puts on above-mentioned projection is input into above-mentioned data reception portion, it is characterized in that the X-axis load cell of measuring the X-direction impact connects in X-direction and is arranged at its part projection outstanding from above-mentioned road surface; Together be provided with oscilaltion mechanism, the Y-axis load cell of measuring the Y direction impact connects the downside that is arranged at above-mentioned projection in Y direction, and wherein above-mentioned X-direction is meant the direction parallel with the road surface, and above-mentioned Y direction is meant the direction vertical with the road surface.
Description of drawings
Fig. 1 is the whole pie graph of the device of mensuration traveling tire impact involved in the present invention.
Embodiment
Below, will the present invention is described in detail based on accompanying drawing.
Fig. 1 is the whole pie graph of the device of mensuration traveling tire impact involved in the present invention.
As shown in the figure, the present invention is a kind of like this impact force measuring apparatus of traveling tire, it is provided with inside and a part of projection 4 of having given prominence to the road surface that is installed on mounting groove 3, so that the tire 2 that travels on road surface 1 is applied impact, and has the data reception portion 5 that to import the impact that is applied by this projection 4, it is characterized in that, measure the X-axis load cell 6 of the impact of relative X-direction, be arranged at above-mentioned projection 4 X-direction phase ground connection; The Y-axis load cell 8 of the impact of relative Y direction together is set and measures with oscilaltion mechanism 7, be arranged at the downside of above-mentioned projection 4 Y direction phase ground connection.
In addition, above-mentioned X-axis load cell 6 is connected with data reception portion 5 by electric wire 9 with Y-axis load cell 8, the bump signal of these X-axis load cells and Y- axis load cell 6,8 can be input to data reception portion 5.
Herein, the direct of travel of tire 2 during X-direction is meant and travels, Y direction is meant the direction vertical with the road surface.
On the other hand, do not damaged by above-mentioned traveling tire 2 in order to protect determinator, on the top of the mounting groove 3 that is provided with projection 4, the mode of joining with the upside with projection 4 also covers with the form of guard shield and to be provided with diaphragm 10.
In addition, projection 4 can be regulated its projecting height with respect to road surface 1 by above-mentioned oscilaltion mechanism 7, is provided with the rolling contact mechanism as rolling bearing 11 between the surface of contact of above-mentioned projection 4 and mounting groove 3.
Then, will describe action of the present invention.
Causing the projection 4 of collision with the traveling tire 2 that is installed on the vehicle on road surface 1 that travels, be installed on the inside of mounting groove 3, its upper end is positioned at from the road surface 1 to outstanding position, top.This projection 4 can be regulated the size of impact and is directly related to the outstanding height in road surface, and this regulates up and down by oscilaltion mechanism 7 and highly realizes.
Cause collision if traveling tire 2 bumps against with projection 4,2 axle load cells that link to each other with projection 4 then, promptly X-axis load cell 6 and Y-axis load cell 8 are measured its impacts, and the data storage of mensuration in data reception portion 5.
Because the data of measuring are the component of 2 directions by this way, therefore can with 2 component and mode calculate the actual power that puts on the tire, for example, when the power with X-direction is made as Fx, when the power of Y direction was made as Fy, the big or small F that puts on the power on the tire was as follows.
F = ( Fx 2 + Fy 2 ) 1 2
The impact of Ji Suaning as described above, the basis of the quantitative data of benchmark that can be when being provided at tire impact evaluation experimental in the laboratory experiment.
In the related traveling tire impact force measuring apparatus of this invention, owing to can guarantee the impact that tire the applied quantitative measurement data corresponding with respect to for actual travel the time with the position of projection, therefore have can be with these data important reference data is used during as the tire striking experiment effect.
