Abstract
The utility model relates to a wheel speed sensor testing device, which is characterized by comprising a base, a shell, a direct-current motor, a gear ring and a wheel speed sensor mounting frame. When the wheel speed sensor testing device is used, a wheel speed sensor is vertically or horizontally clamped on the wheel speed sensor mounting frame, and a probe of the wheel speed sensor is close to the gear ring. After the direct-current motor drives the gear ring to rotate, induced voltage generated by the wheel speed sensor is inputted to an oscilloscope, and a tester can conveniently check the working condition of the wheel speed sensor and regulate the rotating speed of the direct-current motor through a speed regulating knob to detect the wheel speed sensor, so that the wheel speed sensor testing device is extremely convenient.
Description
Technical field
The utility model relates to the wheel speed sensors technical field, especially a kind of wheel speed sensors proving installation.
Background technology
In the ABS system of vehicle, wheel speed sensors transfers to the rate signal of wheel among the ECU, calculates through ECU and obtains the velocity of rotation when front vehicle wheel.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 through wheel speed sensors on the gear ring; The induced voltage that produces is directly proportional with the rotating speed of wheel, obtains the revolution of wheel after the ECU conversion, and ECU repeatedly reduces or increase the rate of skidding that brake pressure on the wheel is controlled wheel according to current rotating speed; It is thus clear that; 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 at present, operation inconvenience.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of simple in structure, wheel speed sensors proving installation that production efficiency is high is provided.
The technical scheme that the utility model is taked is:
A kind of wheel speed sensors proving installation; 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 said control of DC end through 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 said wheel speed sensors erecting frame is fixed on the base through erection column.
The advantage and the good effect of the utility model are:
When the utility model uses; With vertical perhaps being installed on the wheel speed sensors erecting frame of level of wheel speed sensors, 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 be through speed governing knob adjustment direct current generator is very convenient with the detection wheel speed sensors.
