Abstract
The utility model discloses a portable calibrator for an automobile brake road test instrument, which comprises a base where a worm wheel worm decelerator is arranged. An angle coder is arranged at one end of an output rotating shaft of the worm wheel worm decelerator, and a rotating working platform is arranged at the other end of the output rotating shaft of the worm wheel worm decelerator. A rotating hand wheel is arranged at an extending end of the worm, an acceleration sensor in signal connection with the to-be-tested automobile brake road test instrument is arranged on the rotating working platform, and angle values output by the angle coder directly display a standard acceleration value on a display instrument by means of a single chip microcomputer. The portable calibrator for the automobile brake road test instrument has the advantages of being small in volume, light, portable, capable of calibrating numerical reading of a normal-working automobile brake road test instrument, easy to operate and accurate in detection.
Description
Technical field
The utility model relates to a kind of calibrating instrument of automotive inspection equipment, relates in particular to a kind of calibrating instrument that automobile braking road test instrument is proofreaied and correct.
Background technology
At present, the automobile brake effect generally all detects on the damping force monitor station, can not go up that brake test bench detects or when the check-out console measured value had objection, pass through the road method for testing for special car, promptly uses automobile braking road test instrument, detects through the road method for testing.Braking road test instrument is claimed the retarded velocity appearance again, and manufacturer adopts the large revolving calibrating table to carry out the reading adjustment, can't check it its accuracy of reading property of the equipment in the normal use.
Summary of the invention
The utility model technical matters to be solved is exactly the deficiency that overcomes prior art, and a kind of calibrating instrument that can carry out the reading adjustment to the automobile braking road test instrument in the normal use simple to operate, easy to carry is provided.
The technical scheme that the utility model adopted is: the portable vehicle braking road test instrument inspection instrument; Comprise base; On base, be provided with worm type of reduction gearing; End at the output revolving shaft of worm type of reduction gearing is provided with angular encoder, and the other end is provided with rotary table, is provided with rotation hand wheel at the external part of worm screw; On rotary table, be provided with the acceleration transducer that is connected with seized automobile braking road test instrument signal, the angle value of angular encoder output directly demonstrates the normal acceleration value through single-chip microcomputer on Displaying Meter.
The utility model beneficial technical effects is: because the utility model volume is less, in light weight; Thereby be easy to carry; Can carry out the reading adjustment to the automobile braking road test instrument in the normal use, in addition, the utility model directly demonstrates the normal acceleration value through single-chip microcomputer on Displaying Meter; And compare with the displayed value of automobile braking road test instrument, thereby also have simple to operate, detect advantage accurately.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Shown in Fig. 1-3; The portable vehicle braking road test instrument inspection instrument comprises base 9, on base 9, is provided with worm type of reduction gearing 2; End at the output revolving shaft 7 of worm type of reduction gearing 2 is provided with angular encoder 1; The other end is provided with rotary table 4, is provided with rotation hand wheel 10 at the external part of worm screw, on rotary table 4, is provided with the acceleration transducer 6 that is connected with seized automobile braking road test instrument signal; Acceleration transducer 6 usefulness pressing plates 5 are fixed on the rotary table 4, and the angle value of angular encoder 1 output directly demonstrates the normal acceleration value through single-chip microcomputer on Displaying Meter.On rotary table 4, be provided with cross level 12 and fore-and-aft level 11.Below base 9, be provided with horizontal adjustment pin 8.On calibrating instrument, be provided with handle 3, the effect of handle 3 is that convenient taking moved.
As shown in Figure 5, among the figure, g: acceleration of gravity; A: action of gravity is the effective acceleration component on acceleration transducer 6; β: acceleration transducer 6 effective operative orientation and acceleration of gravity angular separations.The portable vehicle braking road test instrument inspection instrument, it is to utilize earth gravity field that acceleration transducer 6 is produced a normal acceleration (gravity acceleration g=9.81m/s
2).When rotary table 4 is in level (angle β=90 ° time), seized automobile braking road test instrument operative orientation line is in horizontality, acceleration a=g * cos 90 °=0 that acceleration transducer 6 is experienced; When rotary table 4 is in the vertical state (angle β=180 ° time), the terrestrial gravitation pedal line is opposite with acceleration transducer 6 useful directions, cos180 ° of the acceleration a=g that acceleration transducer 6 is experienced=-g; When rotary table 4 was in free position, being in angle with the terrestrial gravitation pedal line was β, normal acceleration a=g * cos β that gravity produces acceleration transducer 6.
