[0021] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0022] Embodiment 1:

[0023] The present application provides a modular pneumatic disc brake, comprising a brake bracket 1; cylinder housings 9 are installed at both ends of the brake bracket 1, a brake cylinder 2 is installed inside the cylinder housing 9, a brake block 7 is installed at one end of the brake cylinder 2, a brake pad 3 is installed at one end of the brake block 7 away from a brake pad mounting plate 11, and a piston baffle 13 is embedded and installed inside the cylinder housing 9 near the outer side of the brake cylinder 2;

[0024] Specifically, Figure 1 , Figure 2 and Figure 3As shown, the brake pad 3 is arranged on one side of the brake block 7 by bolts, and the brake block 7 is connected to the brake cylinder 2 through the brake pad mounting plate 11. By pushing the brake cylinder 2 under the action of air pressure, the brake pads 3 on one side of the two groups of brake blocks 7 can be brought close to each other, thereby achieving the braking effect. The brake cylinder 2 and the brake block 7 are modularized and directly installed on the brake bracket 1. The brake pad 3 is enlarged externally and connected to the brake cylinder 2. By embedding the piston baffle 13 into the brake cylinder 2 structure, the total width of the brake is not increased, and the installation space utilization rate is high. By increasing the gap of the brake bracket 1, the maximum thickness of the adapted brake disc reaches 20MM. By improving the cylinder process, increasing the inner diameter of the cylinder, and increasing the size of the brake pad 3, it can achieve a greater braking force. By modularizing the brake cylinder 2 and the brake block 7, the screws can be removed to replace the entire unit, and maintenance is simple and convenient.

[0025] Furthermore, a cylinder air inlet 6 is provided on the side of the brake bracket 1, and air pipes 4 are installed at both ends of the brake bracket 1;

[0026] Specifically, Figure 1 As shown, in order to realize the movement of the brake cylinder 2, the cylinder air inlet 6 is connected to the interior of the cylinder housing 9 through the air pipe 4. By transporting the gas through the cylinder air inlet 6 and the interior of the air pipe 4 to the interior of the cylinder housing 9, the brake cylinder 2 can be prompted to move, thereby achieving the effect of braking.

[0027] Furthermore, a fixing screw hole 5 is installed inside the brake bracket 1;

[0028] Specifically, Figure 1 As shown, in order to achieve fixed installation of the brake bracket 1, a fixing screw hole 5 is provided inside the brake bracket 1. By using a bolt to pass through the fixing screw hole 5 inside the brake bracket 1, the brake bracket 1 can be fixedly installed for use.

[0029] Further, a piston return spring 10 is installed on the outer side of the piston end of the brake cylinder 2;

[0030] Specifically, Figure 2 As shown, in order to reset the brake cylinder 2, a piston reset spring 10 is arranged outside the brake cylinder 2. When the brake cylinder 2 is not pushed by gas, the brake cylinder 2 can be reset by the elastic deformation of the piston reset spring 10 itself.

[0031] Furthermore, a cylinder sealing ring 8 is installed on the outer side of the brake cylinder 2, and the outer surface of the cylinder sealing ring 8 fits the inner wall of the cylinder housing 9;

[0032] Specifically, Figure 2As shown, in order to achieve sealing between the brake cylinder 2 and the cylinder housing 9 when the brake cylinder 2 moves, a cylinder sealing ring 8 is arranged between the brake cylinder 2 and the cylinder housing 9. The cylinder sealing ring 8 can achieve sealing between them to prevent air leakage from affecting the movement of the brake cylinder 2.

[0033] Further, the outer wall of the brake bracket 1 is equidistantly installed with positioning plates 12, the end of the positioning plate 12 away from the brake bracket 1 is installed with a connecting shaft 1201, and the end of the connecting shaft 1201 away from the positioning plate 12 is installed with a limiting plate 1202;

[0034] Specifically, Figure 1 and Figure 4 As shown, in order to facilitate workers to fix and install the cylinder housing 9, multiple groups of positioning plates 12 are arranged at both ends of the brake bracket 1, and the top thereof is rotatably installed with a limiting plate 1202 through a connecting shaft 1201. By placing the cylinder housing 9 between the multiple groups of positioning plates 12, the positioning plate 12 limits the cylinder housing 9, which is convenient for workers to quickly position and install the cylinder housing 9. Then, by rotating the limiting plate 1202, the limiting plate 1202 is located on one side of the cylinder housing 9, which can limit and fix the cylinder housing 9 to prevent the loosening of the bolts from affecting the fixed use of the cylinder housing 9.

[0035] Working principle: By delivering gas to the inside of the cylinder housing 9 through the cylinder air inlet 6 and the inside of the air pipe 4, the brake cylinder 2 can be pushed under the action of air pressure, so that the brake pads 3 on one side of the two sets of brake blocks 7 are close to each other, thereby achieving the braking effect. When there is no gas delivery, the brake cylinder 2 can be reset by the piston reset spring 10.

[0036] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
