DETAILED DESCRIPTION

[0018] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0019] As shown in Figure 1 , Figure 2 , Figure 3 , the adjuster comprises a connecting base 1, an adjusting part 2, a plug-in connector 3 and a sealing assembly, the connecting base 1 is installed on the brake, the inside of the connecting base 1 is provided with a movable hole 4, the adjusting part 2 is in inverted T-shaped structure and movably arranged in the movable hole 4, one end of the adjusting part 2 is connected with a jacking rod 7, the jacking rod 7 is fixed on the brake part of the brake, the opening 8 is located outside the connecting base 1, the plug-in connector 3 is fixed on the opening 8 of the outer edge of the connecting base 1 and connected with an air pressure pipe or a hydraulic oil pipe through a locking nut 9, the sealing assembly comprises a sealing element 10, a sealing ring 11 and a U-shaped sealing ring 5, the sealing element 10 is provided with a guide hole in the center, one end of the adjusting part 2 with the jacking rod 7 passes through the guide hole and forms a movable sealing cavity 12 with the inner wall of the movable hole 4, and the sealing cavity 12 is provided with an elastic reset part 6, wherein the pressure medium is input through the plug-in connector 3 to drive the adjusting part 2 to move along the inner wall of the movable hole 4, drive the brake part to axially displace and realize the fine adjustment of the spacing of the brake part.

[0020] The mechanical structure is combined with pressure driving to support the brake member in the brake to achieve micron-level spacing adjustment, and has a multi-layer sealing design. The structure cooperation of the sealing member 10, the sealing ring 11 and the U-shaped sealing ring 5 makes it adapt to the high-pressure environment.

[0021] The laser ranging sensor 13 is also included and is arranged on the brake to monitor the spacing of the two brake members in real time and feed back the control air pressure / hydraulic pressure value to achieve closed-loop precise adjustment.

[0022] The adjuster is multiple and is symmetrically installed on the brake to cooperatively adjust the spacing of the brake members.

[0023] The multiple adjusters are symmetrically installed to improve the stability and adjustment range of the system, realize closed-loop control after the integration of the laser ranging sensor 13, reduce manual intervention, and at the same time, are compatible with the air pressure / hydraulic system and can be applied to various scenes such as automobile braking and industrial machinery.

[0024] The air pressure pipe or the hydraulic oil pipe is connected to the adjuster through the plug-in connector 3 and the locking nut 9. When an external pressure source such as an air pump or a hydraulic pump is started, the compressed air or the hydraulic oil enters the opening of the connecting base 1 through the plug-in connector 3 and further flows into the bottom of the movable sealing cavity 12. The compressed air or the hydraulic oil accumulates at the bottom of the movable sealing cavity 12 and pushes the adjusting member 2 to move upward along the inner wall of the movable hole 4. The inverted T-shaped design of the adjusting member 2 makes it have a stable moving path in the movable hole 4. The upper end of the adjusting member 2 is rigidly connected to the brake member (such as a brake pad or a brake block) of the brake through the top rod 7. The movement of the adjusting member 2 is directly converted into the axial displacement of the top rod 7, thereby driving the brake member to move synchronously. If the adjusting member 2 moves upward, the top rod 7 pushes the brake member to approach the other brake member, thereby reducing the spacing.

[0025] The elastic reset member 6 is arranged in the movable sealing cavity 12. When the compressed air and the hydraulic oil are released or the pressure is reduced, the rebound force of the elastic reset member 6 drives the adjusting member 2 to return to the initial position, thereby ensuring the stability of repeated use of the adjuster. The sealing member 10 is tightly matched with the inner wall of the movable hole 4 and avoids medium residue or external impurities interference through the sealing ring 11 and the U-shaped sealing ring 5, thereby ensuring the accuracy of the reset action. The central guide hole of the sealing member 10 guides the movement of the adjusting member 2 and forms a dynamic seal with the inner wall of the movable hole 4. The sealing ring 11 is located between the sealing member 10 and the inner wall of the movable hole 4 to prevent the medium from leaking along the axial direction. The U-shaped sealing ring 5 is arranged at the lower end of the adjusting member 2 and is attached to the inner wall of the movable hole 4 when the adjusting member 2 moves, thereby forming a bidirectional seal to prevent medium leakage and avoid external pollutants from entering.

[0026] The laser ranging sensor 13 installed on the brake feeds back the distance between the two brake pieces in real time, and feeds back the data to the control system. The control system automatically adjusts the input pressure value according to the sensor data, such as increasing the hydraulic oil pressure to reduce the distance, or reducing the air pressure to expand the distance, to realize millimeter-level or even micron-level closed-loop precise adjustment. Multiple adjusters cooperate to realize symmetrical installation and load balancing: multiple adjusters (such as 4) are installed symmetrically on both sides or around the brake, and the brake piece distance is adjusted uniformly by synchronously driving the adjuster 2, so as to avoid uneven force of single point and cause eccentric wear or jam. If one adjuster fails due to failure, the remaining adjusters can still maintain the basic function through cooperative compensation, thereby improving the system reliability.

[0027] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.

[0028] Although the terms are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for the convenience of describing and explaining the essence of the present application; any interpretation of them as any kind of additional limitation is contrary to the spirit of the present application.
