ABS sensor tooth ring utilizing differential speed ratio for automatic cleaning

Abstract

The invention relates to the technical field of automobile sensor equipment, and discloses an ABS sensor tooth ring utilizing the differential speed ratio for automatic cleaning. A tooth ring body isincluded. The front face of the tooth ring body is movably in cup joint with an outer ring. Cleaning plates extending into tooth grooves of the tooth ring body are movably inserted and connected in the outer ring. The position, located on the right side of each cleaning plate, in the outer ring is fixedly connected with a cylinder, and the front faces of connecting plates are rotationally connected with gears. The telescopic cleaning plates are arranged in the outer ring, when an automobile normally runs, since the rotation speed difference exists between the tooth ring body and the outer ring, the cleaning plates are extruded to the outer side of the tooth ring body, and normal work of the tooth ring body and an ABS sensor probe is prevented from being influenced. When the automobile stops, the cleaning plates are inserted in the tooth grooves in the tooth ring body, dust and other impurities are jacked away, time and labor are saved, and automatic cleaning work is finished on the premise that normal running of a BAS system is not influenced.

Description

technical field [0001] The invention relates to the technical field of automotive sensor equipment, in particular to an ABS sensor ring gear that uses a differential speed ratio to automatically clean itself. Background technique [0002] The wheel sensor is an important device in the ABS system that monitors the operation of the vehicle at all times. Its structure mainly includes two parts: the sensor probe and the ring gear. The ring gear is fixedly installed on the wheel hub of the car. There is a very small gap between the sensor probe and the ring gear. Using the principle of magnetic induction to monitor, oil and dust are easy to accumulate in the tooth groove of the ring gear. The dust contains a lot of metal debris, which will have a great impact on the wheel speed information collected by the sensor, and then affect the ABS. The performance of the system, so the ring gear must be cleaned regularly. Since there should be a gap of 0.5-1mm between the ring gear and the...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an ABS sensor ring gear that uses the differential ratio to automatically clean the ring gear, which has the advantages of automatically cleaning the ring gear without affecting the normal operation of the ABS system, saving time and effort, and solving the problem of The traditional ABS sensor ring gear needs to be disassembled and then cleaned, which is not only troublesome to operate, but also time-consuming and labor-intensive.
