ELECTRIC TYPE ABRASION SENSOR UNIT FOR BRAKE PAD CAPABLE OF PREVENTING THE DIRECT HIGH TEMPERATURE EXPOSURE IN THE BRAKE BY PREVENTING THE SENSOR EXPOSURE TOWARDS THE WHEEL DISK OR THE METAL OBJECT

摘要

PURPOSE: An electric type abrasion sensor unit for brake pad is provided to prevent the inflow of the worn pad dust and foreign material by determining the pad abrasion using the movement change of the caliper according to the pad abrasion.;CONSTITUTION: An electric type abrasion sensor unit comprises a torque member(4) and a sensor. The torque member is formed in a pair of caliper bodies transferring the pad located in both sides of the wheel disk towards the wheel disk. The sensor informs the replacement time of the pad. The sensor is installed by using the guide rod inserted into the torque member to the pierced guide rod hole. The sensor comprises a stopper sensor, a metal pin(3), and an electric signal line. The stopper sensor forms the sensitive stage into the inner space. The metal pin goes through the sensitive stage according to the abrasion rate of the pad. The electric signal line comprises an indicator informing the change time of the pad in the stopper sensor.;COPYRIGHT KIPO 2011
