Automatic clearance adjustment for parking brake drum and brake lining

摘要

This study is about parking brake,More specifically, the distance between the brake lining head and the brake drum sensed by the displacement sensor drives the electric actuator with the heating layer in mycom with the preset value, so as to recover the interval adjuster,In order to compensate for the decrease of power generated by the decrease of brake lining thickness, the power of the parking brake is maintained to a certain extent by the clearance automatic adjustment device between the parking brake drum and the brake lining.On the automobile brake device with the space between the brake drum and the brake lining adjusted,The spacing adjusting gear formed with the tooth row on the outer surface of the spacing adjusting nut is provided,One side fixes the body, merges with the interval adjusting gear and organizes the worm gear of the interval adjusting nut,A luminous part and a displacement sensor with a water luminous part for measuring the distance between the brake drum and the brake lining are fixedly combined with the outer side of the brake lining,The measured distance sensed from the displacement sensor is compared with the preset value. When the value exceeds the preset value, it has the characteristics of Mani combination for operating the above-mentioned sports equipment.
