Abstract
The invention discloses a calibrating instrument for an automobile brake road tester, comprising a base and a worm gear reducer which is arranged on the base, wherein, one end of an output rotating shaft of the worm gear reducer is provided with an angle coder, and the other end of the output rotating shaft of the worm gear reducer is provided with a rotary table; a rotary handwheel is arranged on an extending end of a worm; the rotary table is provided with an acceleration transducer which is connected with a signal of the detected automobile brake road tester; and a standard acceleration value is directly displayed on a display instrument by an angle value outputted from the angle coder through a singlechip. The calibrating instrument for the automobile brake road tester has the advantages of small volume, light weight, convenient portability, reading calibration for the automobile brake road tester in regular service, simple operation and accurate detection.
Description
Technical field
The present invention relates to a kind of calibrating instrument of automotive inspection equipment, relate 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 by the road method for testing.
Braking road test instrument claims the retarded velocity instrument again, and manufacturer adopts the large revolving calibrating table to carry out the reading adjustment, can't check it its accuracy of reading of the equipment in the normal use.
Summary of the invention
Technical matters to be solved by this invention overcomes the deficiencies in the prior art exactly, 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 solution adopted in the present invention is: automobile 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, the other end is provided with rotary table, external part worm screw is provided with rotation hand wheel, be provided with the acceleration transducer that is connected with tested automobile braking road test instrument signal on rotary table, the angle value of angular encoder output directly demonstrates the normal acceleration value by single-chip microcomputer on Displaying Meter.
Beneficial technical effects of the present invention is: because volume of the present invention 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 present invention directly demonstrates the normal acceleration value by 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 drawings and Examples the present invention is further described:
As Figure 1-3, automobile braking road test instrument inspection instrument, comprise base 9, on base 9, be 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, external part worm screw is provided with rotation hand wheel 10, on rotary table 4, be provided with the acceleration transducer 6 that is connected with tested 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 by 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.Be provided with handle 3 on calibrating instrument, 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: degree sensor 6 effective operative orientation and acceleration of gravity angular separations.
Automobile 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), when tested 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, the acceleration a=gcos180 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.
