Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please limited range.
Described in the utility model is a kind of vehicle start dynamic performance and testing, and main structure includes measuring device and anti-
Electro-optical device；The measuring device include circuit board 1, equidistant parallel optoelectronic switch 2 arranged side by side, indicator light 3, protective resistance 4,
Power supply, the circuit board 1 are located in the bar shaped geosyncline 5 below of road surface, the optoelectronic switch 2, indicator light 3, protective resistance 4, electricity
Source-series connection；The reflex reflector includes round seat 6 and the quadrangular 7 that 6 center of round seat is arranged in, and the round seat 6 is separate
The side of quadrangular 7 is embedded with magnet block 8, and the outer surface of the magnet block 8 will match according to the cambered surface or plane of driving wheel the center point
Setting is closed, the round seat 6 of reflex reflector is adsorbed by magnet block 8 by magnetic force the wheel hub the center point of driving wheel, and wheel hub
Centrifugal force or centrifugal force very little is not present in the center of circle, and driving wheel will not throw away reflex reflector when rotating.Four of the quadrangular 7
Side is wherein reflective mirror 9 on one side, and excess-three face is rough surface, and rough surface is non-reflective, and the round seat 6 of reflex reflector passes through magnet block
8 are fixed to the center location of driving wheel of vehicle, and the side of reflex reflector quadrangular 7 is corresponding with optoelectronic switch 2.

The setting of lamp 3 is arranged side by side.The width of the reflective mirror 9 is more than or equal to the distance between two neighboring optoelectronic switch 2, this just keeps away
When exempting from the reflective mirror 9 of reflex reflector and being directed at the gap between two neighboring optoelectronic switch 2, lead to indicator light 3 at this node not
It is bright.
Protective glass plate 11 is erected on the bar shaped geosyncline 5.Since protective glass plate 11 will appear the refraction of light, so
Protective glass plate 11 is removed when measurement, protective glass plate 11 is set up into ceiling on bar shaped geosyncline 5 again after being measured
Measuring device in shape geosyncline 5.
Application method and principle:
Optoelectronic switch 2 is to connect circuit by synchronization loop using detected material blocking or reflect to light beam.Optoelectronic switch
2 circuits are made of transmitter, receiver and detection circuit three parts.When vehicle launch, circle is located in driving wheel rotation process
Reflex reflector at the heart can also be followed by driving wheel rotation, when the 9 side face optoelectronic switch of reflective mirror of reflex reflector quadrangular 7
When 2, the light that the transmitter of optoelectronic switch 2 issues is received by the reflection of reflective mirror 9 by receiver, so that optoelectronic switch 2 be made to connect
It is logical, it is connected by optoelectronic switch 2, indicator light 3, protective resistance 4, the concatenated detection circuit of power supply, indicator light 3 brightens.Therefore, it drives
Wheel per revolution has an indicator light 3 and brightens:
According to Figure of description Fig. 5, principle explanation is carried out:
Compared with 1 by comparing the outer circumference L of driving wheel with two neighboring the distance between the indicator light 3 that brightens,
It obtains difference between the two, that is, can determine whether the skidding distance of driving wheel.As shown in Figure of description Fig. 5, △ La=L-L1；△
Lb=L-L2；△ Lc=L-L3, △ La, △ Lb, △ Lc more level off to zero, indicate vehicle slip apart from smaller.
If 2 △ La, △ Lb numerical value are larger, △ Lc levels off to zero, then in L3 sections of driving wheels close to non-slip driving status, institute
To be about the sum of L1+L2+L3 numerical value the distance between from starting moment to normally travel.
3 by observe other than when 3 stationary vehicle of origin indicator light is in origin the bright number of other indicator lights 3 come determine drive
Driving wheel, which skids, encloses number.
4 by changing starting power, and L1 is approximately equal to L when measurement, and driving wheel will not skid under corresponding starting power.
Certainly, 2 row of optoelectronic switch due to that can not be arranged side by side always parallel with equidistant parallel in vehicle travel process
It sails, this error, which will lead to △ L, in vehicle travel process can only level off to zero, it is difficult to be equal to zero, so, △ L in test process
It can be defaulted as △ L within 2cm or 3cm and level off to zero.
