Braking Process: When braking is required, the air chamber pusher rod pushes the pressure arm to rotate. This rotation not only generates braking displacement but also increases braking force. This braking force and displacement are then transmitted to the reference seat. The reference seat, in turn, pushes the inner friction pad via the screw, eliminating the gap between it and the brake disc. Simultaneously, the brake caliper moves inward under the reaction force, causing the outer friction pad to fit tightly against the brake disc, achieving the braking effect.
Brake Return: After releasing the brake pedal, the air pressure in the air chamber is released, and the return spring activates, returning the reference seat and screw to their initial positions. This maintains a certain gap between the brake disc and the friction pad, preparing for the next braking action.
Automatic Compensation: To maintain the gap between the friction pad and the brake disc within a suitable range, the brake is equipped with an automatic compensation mechanism. This mechanism checks the gap value in each working cycle. If the gap exceeds the set value, the mechanism adjusts the gap by rotating the threaded pair, ensuring the gap between the friction pad and the brake disc is between 0.7 and 1.2 mm. Too small a gap may cause overheating in the braking area, while too large a gap may lead to insufficient braking force or failure.
