Operating principle of pneumatic caliper disc brake QP12.7-A QP25.4, QP30-D, CQP12.7, QP38, CQP40-D pneumatic caliper Disc brake frame and cylinder are composed of two parts. When cylinder 1 is filled with pressure air, piston rod 5 quickly contracts into the cylinder under the action of air pressure. The left and right brake arms, under the action of return spring 4, drive the friction block 12 to quickly open (i.e. release the brake). When the cylinder stops supplying air and quickly deflates through the control valve, the piston rod 5 quickly extends under the internal spring of the cylinder, pushing the left and right brake arms to drive the friction block 12 to close (i.e., the holding brake).

2、 Installation of pneumatic caliper disc brake 1. First, check the brake surface of the brake disc and brake pad for oil sludge or other stains. 2. Install the G3/8 "(cast iron rod cylinder) or 1/2" (cast aluminum cylinder) connector on the air inlet of cylinder 1, connect the air pipe with a hose, and the air source should be free of oil, water, and other impurities 3. During installation, pressure air is first introduced to retract the piston rod 5 into the cylinder. Then, the friction block 12 is installed in the direction perpendicular to the brake disc, and the base 9 is fixed horizontally on the rigid base so that its center is in line with the thickness center of the brake disc. The installation position dimensions are shown in the structural diagram

3、 Adjustment of pneumatic caliper disc brake a) Adjust the air pressure value, which is 5~7 bar. b) For normal work, the first step is to test the brake several times and check if there are any abnormalities in the brake. c) The retraction distance of the friction block can be adjusted by rotating the adjustment rod 6 to change the size of the working stroke. When rotating the adjustment rod, pressure air is first introduced to retract the piston rod, and then adjusted.

4、 Maintenance of pneumatic caliper disc brake When the friction plate is worn and the working stroke increases to 8mm, it is necessary to immediately adjust rod 6 to readjust the working stroke to about 4mm, otherwise the brake will fail. After adjustment, tighten nut 7. When the friction block 12 is worn to about 6mm, replace the wear block. The replacement steps are as follows: 1. Cylinder, 2. Right brake arm 3. Reset spring 5. Piston rod 6. Adjustment rod 7. Nut 8 Left brake arm 9, base 10, brake block 11, spring steel wire 12, friction block

The disc brake has hydraulic type, which is controlled by hydraulic pressure. The important parts include brake disc, wheel cylinder, brake caliper, oil pipe, etc. The disc brake features fast heat dissipation, light weight, simple structure and convenient adjustment. In particular, under high load, it has good heat resistance, stable braking effect, and is not afraid of mud and water. When driving in winter and under bad road conditions, many car disc brakes have flat brake discs, perforated brake discs, and scoring brake discs. Among them, scoring brake discs have good braking effect and ventilation and heat dissipation capacity.

The pneumatic disc brake applies force along the brake disc, the brake shaft is free from bending moment, and the radial dimension is small.

Compared with the drum brake, the working surface of the disc brake is flat and heat transfer occurs on both sides. When the disc rotates, it is easy to cool and not easy to change significantly. The braking efficiency is relatively stable. After a long time of use, the brake disc has enhanced its braking effect due to high-temperature expansion; The drum brake has a single side heat transfer and a large temperature difference between the inside and outside, which makes the brake drum prone to deformation. At the same time, after prolonged braking, the brake drum expands due to high temperature, and the braking efficiency is weakened. In addition, the disc brake is simple in structure, convenient in maintenance, and easy to realize automatic adjustment of brake clearance.

The disadvantage of the disc brake is that the friction plate acts directly on the disc, without automatic friction amplification, and the braking efficiency is low. If the brake actuating pipeline pressure is high when used in the hydraulic braking system, a power auxiliary device must be installed separately; When also used for parking brake, the added parking brake transmission device is more complex than the drum brake, so its application in the rear wheels is limited by
