What is the working principle of air brakes?
1 Answers
Air brakes work by pressing the brake pedal, which allows compressed air to enter the front brake cylinder and rear brake spring cylinder through a one-way valve. This action pushes the brake arm, causing the brake cam to rotate and expand the brake shoes to tightly contact the brake drum, achieving the braking effect. Below are specific details about air brakes: 1. Components: The air brake system consists of a brake control mechanism, dual-circuit brake mechanism, central disc brake mechanism, brake, and air compressor, among others. 2. Air brake technique: Vehicles with air brakes require at least 3 bars of pressure to move, ensuring effective braking performance.
