What is an automatic brake clearance adjustment device?
1 Answers
The automatic brake clearance adjustment arm, commonly known as the automatic brake shoe clearance adjustment arm or simply the automatic adjustment arm, automatically and promptly adjusts the increased clearance caused by wear, ensuring the brake clearance remains within the designed range. It does not adjust for the angular travel of the adjustment arm that occurs due to the elastic deformation of force-transmitting components after the brake shoe contacts the brake drum. Relevant information about braking is as follows: 1. Introduction: Refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transport tools, or machinery. 2. Principle: The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.
