Abstract
The invention relates to a wheel speed sensor tester, which is characterized by comprising a pedestal, a casing, a direct current motor, a gear ring and a wheel speed sensor installation frame. When the wheel speed sensor tester is used, a wheel speed sensor is vertically or horizontally clamped on the wheel speed sensor installation frame, and the probe of the wheel speed sensor is close to the gear ring; and when the gear ring is driven to rotate by the direct current motor, induced voltage which is generated by the wheel speed sensor is input into an oscilloscope, test staff can conveniently check the working situation of the wheel speed sensor, and can regulate the rotating speed of the direct current motor by a speed regulating knob so as to detect the wheel speed sensor. Therefore, the wheel speed sensor tester is very convenient.
Description
Technical field
The present invention relates to the wheel speed sensors technical field, especially a kind of wheel speed sensors test machine.
Background technology
In the ABS system of vehicle, wheel speed sensors transfers to the rate signal of wheel among the ECU, calculates the velocity of rotation of obtaining when front vehicle wheel through ECU.The probe of wheel speed sensors is installed in the outside of wheel institute toothing circle at interval, cause the strong and weak variation in magnetic field when tooth peak and tooth paddy are by wheel speed sensors on the gear ring, the induced voltage that produces is directly proportional with the rotating speed of wheel, after converting, ECU obtains the revolution of wheel, ECU repeatedly reduces or increases the rate of skidding that brake pressure on the wheel is controlled wheel according to current rotating speed, as seen, the operate as normal of wheel speed sensors whether direct relation the safety of vehicle, the quality detection device complex structure of wheel speed sensors is operated inconvenience at present.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple in structure, wheel speed sensors test machine that production efficiency is high is provided.
The technical scheme that the present invention takes is:
A kind of wheel speed sensors test machine, it is characterized in that: comprise base, shell, direct current generator, gear ring and wheel speed sensors erecting frame, shell is installed on the base, direct current generator is installed in the shell, this direct current generator stretches out coaxial installation gear ring on the output shaft of shell, on the base in the gear ring outer face outside with the gear ring installation wheel speed sensors erecting frame of contraposition mutually, on the wheel speed sensors erecting frame, be shaped on the through hole that clamps wheel speed sensors, setting-in display module and speed governing knob on the shell, display module all is connected a central control module with the speed governing knob, central control module connects described control of DC end by the DC motor speed-regulating control module, and the Hall element module that is used to measure dc motor speed is installed in the shell.
And described wheel speed sensors erecting frame is fixed on the base by erection column.
Advantage of the present invention and good effect are:
When the present invention uses, with wheel speed sensors vertically or being installed on the wheel speed sensors erecting frame of level, the probe that makes wheel speed sensors is near gear ring, after direct current generator drives the gear ring rotation, the induced voltage that wheel speed sensors produces is input in the oscillograph, the tester can check the working condition of wheel speed sensors easily, and the rotating speed that the tester can adjust direct current generator by the speed governing knob is very convenient with the detection wheel speed sensors.
