Air Spring Caliper Piston Brake

Pneumatic brakes are mainly composed of five core components: brake frame (including brake arm/caliper body), cylinder (airbag), return spring, friction pad (brake block), and clearance adjustment mechanism. ‌‌
Detailed explanation of core components
Brake frame/caliper body: usually a cast steel or aluminum alloy integrated structure, used as the load-bearing body to connect the left and right brake arms, responsible for transmitting clamping force and supporting other components.
Cylinder (airbag): Compressed air execution unit, containing a piston inside; When the air pressure (usually 5-7 bar) is introduced, the piston is pushed to overcome the spring force to achieve "release", and during exhaust, it relies on the spring force to reset and achieve "braking".
Reset spring: A high elasticity spring set (such as the QP30 series with 12 springs) built into the normally closed design, which provides braking torque in the absence of air pressure, ensuring safe braking in the event of power/gas failure.
Friction pad: Made of asbestos free and environmentally friendly materials, the brake pad/pad directly rubs against the brake disc to generate braking force. Some designs support quick replacement and have automatic positioning function.
Adjustment mechanism: used for precise adjustment of braking clearance and braking torque (usually supports multi-stage adjustment), ensuring uniform clearance between left and right brake pads and matching braking force requirements. ‌‌
