Movable type anti-lock brake system (ABS) gear detecting device

Abstract

The invention discloses a movable type anti-lock brake system (ABS) gear detecting device which comprises a supporting seat. The movable type ABS gear detecting device is characterized in that a rotation shaft is rotatably installed on the supporting seat, a transmission gear is installed at the output end of the rotation shaft, a synchronous pulley is installed at the other end of the rotation shaft, the synchronous pulley is driven by a motor on one side of the synchronous pulley, a horizontal lead screw and a horizontal guide rod are erected on one side of the supporting seat, a slide seat is matched with the lead screw in a spiral, a guide hole matched with the guide rod is arranged on one side of the slide seat, a location shaft is rotatably installed on the slide seat, a protrusion matched with a gear key groove to be detected is arranged on the upper end portion of the location shaft, an annular protruding platform is arranged on the location shaft below the protrusion, and the lead screw is driven by the motor. The movable type ABS gear detecting device uses a mode that a synchronous belt is driven by the motor to be connected with a bearing, improves balance quality of the shaft, reduces errors and greatly improves detection accuracy. Simultaneously, ABS gears are easy to locate and accurate in location, and detection of the ABS gears in different types can be met.

Description

technical field [0001] The invention relates to a gear detection device, in particular to a movable ABS gear detection device. Background technique [0002] Electronic control technology is widely used in modern automobiles, and a large number of electromechanical hydraulic and electromechanical integration designs controlled by microcomputers are used. The ABS system is such a system. The ABS system uses four wheel speed sensors as input signals. In order to ensure the normal operation of the ABS system , all wheel speed sensor signals must be inspected before leaving the factory. Usually, this signal detection method mostly uses ABS sensor detection equipment to detect it. Its structure is complex and its manufacturing cost is high. The detection output data is displayed through the scale value. The detection of the sensor shows that the data jitter value is small, it is not easy to observe and detect, and it cannot be used. In order to solve this problem, most of the exis...

[0002] Electronic control technology is widely used in modern automobiles, and a large number of electromechanical hydraulic and electromechanical integration designs controlled by microcomputers are used. The ABS system is such a system. The ABS system uses four wheel speed sensors as input signals. In order to ensure the normal operation of the ABS system , all wheel speed sensor signals must be inspected before leaving the factory. Usually, this signal detection method mostly uses ABS sensor detection equipment to detect it. Its structure is complex and its manufacturing cost is high. The detection output data is displayed through the scale value. The detection of the sensor shows that the data jitter value is small, it is not easy to observe and detect, and it cannot be used. In order to solve this problem, most of the existing technologies use special detection tools and are equipped with expensive digital acquisition and molecular systems. The detection tools in this equipment The matching accuracy of the ABS sensor to be tested seriously affects the test results, so the ABS gear needs to be tested before the tooling is made, so as to make a suitable tooling according to the relevant parameters of the ABS gear, but the existing testing is mainly driven directly by the motor The gear rotates, the detection error is relatively large, and the position of the ABS gear is not easy to determine or the position is inaccurate, which affects the measurement result
