[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3 The brake disc pressure ring shown in the figure comprises a pressure ring body, which is composed of an outer support ring 1, an inner support ring 2 and a plurality of middle support blocks 3; The connecting surface between the outer support ring 1 and the middle support block 3 has an outer extrusion rod 4 of an integral structure, the connecting surface between the inner support ring 2 and the middle support block 3 has an inner extrusion rod 5 of an integral structure, an internal hydraulic chamber 6 is opened inside the middle support block 3, and outer extrusion through holes matching the outer extrusion rod 4 and the inner extrusion rod 5 are respectively opened on the two side walls of the middle support block 3, an external feed hole 7 is opened on the outer arc surface of the middle support block 3, and the internal thread of the external feed hole 7 is equipped with a one-way check bolt 8.

[0022] Working principle: the outer support ring 1 is connected to the middle support block 3 by inserting the outer extrusion rod 4 into the outer extrusion through hole, and the inner support ring 2 is connected to the middle support block 3 by inserting the inner extrusion rod 5 into the outer extrusion through hole.

[0023] A plurality of middle support blocks 3 between the outer support ring 1 and the inner support ring 2 form an annular structure.

[0024] In order to cooperate with the inner and outer sliding assembly, the outer support ring 1 is inserted into the outer extrusion through-hole through the outer extrusion rod 4 and slidably assembled with the middle support block 3, and the inner support ring 2 is inserted into the outer extrusion through-hole through the inner extrusion rod 5 and slidably assembled with the middle support block 3.

[0025] In order to facilitate lateral adjustment, a lateral adjustment groove 9 with a fan-shaped structure is opened on the outer side surface of the middle support block 3.

[0026] In order to facilitate external control and improve the lateral limiting capability, a flip rod 10 is provided inside the lateral adjustment groove 9 through an axis, and a lateral limiting block 11 of an integral structure is provided on the side wall of the flip rod 10 .

[0027] In order to facilitate assembly and adjustment, a lateral telescopic hole matching the outer extrusion through hole is opened on the inner side of the lateral adjustment groove 9, and the lateral limit block 11 is inserted into the outer extrusion through hole and slidably sealed with the outer extrusion through hole.

[0028] In order to cooperate with the lateral limitation, lateral limiting grooves 12 that cooperate with the lateral limiting blocks 11 are opened on the outer sides of the outer layer extrusion rod 4 and the inner layer extrusion rod 5 .

[0029] In order to cooperate with the threaded assembly, the outer opening of the external feed hole 7 is provided with an internal thread locking hole that cooperates with the one-way check bolt 8, and the outer opening of the internal thread locking hole is provided with a sinking groove that cooperates with the one-way check bolt 8.

[0031] An external sealing cover for closing the embedded one-way check valve 82 is fixedly connected to the outer end of the external threaded bolt 81 to improve safety. The embedded one-way check valve 82 can fill the external hydraulic oil into the internal hydraulic chamber 6 to prevent the internal hydraulic oil from being discharged.
