[0022] 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;

[0023] Embodiment 1:

[0024] The present application provides a pneumatic disc brake, comprising an upper cylinder head 1; a large piston plate 5 is installed on the inner top of the upper cylinder head 1, a lower cylinder head 2 is installed on the bottom of the large piston plate 5, and a cylinder top rod 3 is installed on the inner top of the upper cylinder head 1;

[0025] Specifically, Figure 1 and Figure 2 As shown, the large piston plate 5 and the cylinder top rod 3 inside can be protected by the upper cylinder head 1 and the lower cylinder head 2. By passing gas into the upper cylinder head 1 and the lower cylinder head 2, the large piston plate 5 can drive the cylinder top rod 3 to be pushed out, thereby achieving braking. By making the upper cylinder head 1 into a piston-type cylinder top rod 3, the force-bearing area of ​​the piston can be increased, thereby achieving the effect of increasing the thrust.

[0026] Furthermore, a sealing ring 7 is installed between the large piston plate 5 and the upper cylinder cover 1;

[0027] Specifically, Figure 4 As shown, in order to achieve sealing between the large piston plate 5 and the upper cylinder head 1, a sealing ring 7 is arranged on the outer side of the large piston plate 5. The sealing ring 7 can maintain sealing between the large piston plate 5 and the upper cylinder head 1, while reducing the friction between the large piston plate 5 and the upper cylinder head 1 when moving.

[0028] Furthermore, an air inlet 6 is provided inside the upper cylinder head 1;

[0029] Specifically, Figure 1 and Figure 2 As shown, in order to realize the gas delivery to the interior of the upper cylinder head 1 and the lower cylinder head 2, the large piston plate 5 drives the cylinder top rod 3 to move, and the gas can be delivered to the interior of the upper cylinder head 1 through the air inlet 6, and then the large piston plate 5 can drive the cylinder top rod 3 to be ejected, thereby achieving the braking effect.

[0030] Further, flanges 8 are installed on the outer sides of the upper cylinder head 1 and the lower cylinder head 2, and cylinder locking screws 4 are installed inside the flanges 8;

[0031] Specifically, Figure 1 As shown, in order to achieve a fixed connection between the upper cylinder head 1 and the lower cylinder head 2, flanges 8 are provided on the outer sides of the upper cylinder head 1 and the lower cylinder head 2. By using the cylinder locking screws 4 to pass through the inside of the flange 8, the upper cylinder head 1 and the lower cylinder head 2 can be fixedly connected.

[0032] Furthermore, a connecting ring 9 is installed on the outer side of the lower cylinder head 2 close to the cylinder top rod 3, and a cleaning ring 901 is provided on the inner wall of the connecting ring 9;

When the cylinder top rod 3 moves, the foreign matter adhered to the outer surface of the cylinder top rod 3 can be processed through the cleaning ring 901 to avoid affecting the movement of the cylinder top rod 3.

[0034] Further, a lubrication ring 902 is provided inside the connecting ring 9;

[0035] Specifically, Figure 3 As shown, in order to achieve better movement of the cylinder top rod 3, a lubricating ring 902 is arranged on the inner wall of the connecting ring 9. The lubricating ring 902 can be used to directly apply lubricating oil to the outer surface of the cylinder top rod 3, thereby reducing the friction between the cylinder top rod 3 and the lower cylinder head 2, which can promote better movement of the cylinder top rod 3.

[0036] Working principle: By delivering gas to the interior of the upper cylinder head 1 through the air inlet 6, the large piston plate 5 can drive the cylinder push rod 3 to be pushed out, thereby achieving a braking effect. At the same time, the sealing ring 7 can keep the large piston plate 5 and the upper cylinder head 1 sealed, and at the same time reduce the friction between the large piston plate 5 and the upper cylinder head 1 when moving.

[0037] 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.
