COMMERCIAL VEHICLE DISC BRAKE CALIPER BODY ASSEMBLY

The present invention relates to a commercial vehicle disc brake caliper assembly comprising a caliper body ,and a left guide pin component ,right guide pin component, the main adjuster mechanism assembly, the driven adjuster unit are all mounted on the caliper body. The adjuster mechanism assembly adopts a gear clutch structure with anti-overload function; the driven adjuster unit adopts a circlip structure; the main adjuster assembly and the driven adjuster unit is connected by sprocket chain. The bottom of the main adjuster assembly and the bottom of the driven adjuster unit are connected to the three thread calibration bolt, which connected with bridge, the bridge are arranged inside of the brake caliper. The invention overcomes the problems which may occur during braking, such as uneven braking force, failure of clearance adjustment, deformation of adjuster mechanism, failure of braking, etc. When the invention applied to the brake, it can eliminate potential safety problems among various parts of the adjuster mechanism, and improves brake service life and stability.
