Description

Technical Field

[0001] This utility model relates to the field of brake technology, and in particular to a disc brake with an automatic reset function. Background Technology

[0002] Friction pads, also known as friction discs, are friction materials fixed on a rotating brake disc of a machine. The friction pads and friction blocks therein withstand external pressure and generate friction to achieve the purpose of slowing down or stopping the machine.

[0003] Regarding the aforementioned technologies, the inventors believe that the existing brakes have the following defects: after the brakes are released, the components may not reset in a timely or complete manner, which affects the braking effect and normal operation of the equipment. Therefore, this utility model provides a disc brake with an automatic reset function. Utility Model Content

[0004] The purpose of this application is to provide a disc brake with an automatic reset function to solve the problem mentioned in the background art that some brakes may not reset in a timely or complete manner after the brake is released, which affects the braking effect and normal operation of the equipment.

[0005] To achieve the above objectives, this application provides the following technical solution: a disc brake with automatic reset function, including a mounting base, a bracket provided on the outer side of the mounting base, a fixing block fixedly connected to the top and bottom of the bracket, a force arm provided on the outer side of the fixing block, the fixing block being connected to the inner wall of the force arm via a pin, a cylinder provided between a pair of force arms, and a braking component provided on the outer side of each force arm.

[0006] Preferably, the braking assembly includes a friction pad block movably connected to the inner wall side of the lever arm, a sliding rod fixedly connected to the outer side of the friction pad block, a sliding cylinder slidably connected to the outer side of the sliding rod, a spring sleeved on the outer side of the sliding cylinder, and the two ends of the spring being fixedly connected to the outer side of the sliding cylinder and the friction pad block, respectively.

[0007] Preferably, a friction plate is fixedly connected to the outer side of the friction plate pressure block, and a through hole adapted to the friction plate pressure block is opened on the inner side of the lever arm.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, the friction plate clamping block, friction plate, sliding cylinder, spring, and sliding rod are coordinated to clamp the friction plate clamping block, friction plate, and friction material, thereby stopping the equipment from running. When the cylinder resets, the sliding cylinder slides along the sliding rod under the action of the spring, causing the power arm to automatically reset.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The disc brake shown includes a mounting base 1, which is used to fix the disc brake in the required equipment position, providing a stable mounting foundation for the entire brake and ensuring that it will not shift during operation. A bracket 2 is provided on the outer side of the mounting base 1, which serves to support and connect the mounting base 1 to other components, making the entire brake structure more stable. Fixing blocks 3 are fixedly connected to the top and bottom of the bracket 2, which are used to install and fix the lever arm 4, ensuring that the lever arm 4 can rotate stably around the pin during operation, providing a reliable connection point for subsequent power transmission. The lever arm 4 is located on the outer side of the fixing block 3, and the lever arm 4 plays a role in transmitting force in the entire braking system. Through its rotation, it transmits the force output by the cylinder 5 to the braking assembly, thereby realizing the braking function. The fixing block 3 is connected to the inner wall of the lever arm 4 through the pin. This connection method allows the lever arm 4 to rotate flexibly to adapt to different working conditions. A cylinder 5 is installed between a pair of lever arms 4. The cylinder 5 serves as a power source, and its output force is transmitted to the lever arms 4 through the connecting rod 14, causing the lever arms 4 to rotate. This enables the braking assembly to brake the disc, providing the necessary power for the entire braking process. Braking assemblies are installed on the outer sides of the lever arms 4. The braking assembly includes a friction pad pressure block 6 that is movably connected to the inner wall of the lever arm 4. The friction pad pressure block 6 can move on the lever arm 4. When the lever arm 4 rotates, it can drive the friction pad pressure block 6 to move, thereby achieving the pressing and releasing action of the friction pad 9 and controlling the braking effect. A sliding rod 11 is fixedly connected to the outer side of the friction pad pressure block 6. The sliding rod 11 can slide inside the sliding cylinder 7, serving as a guide to ensure that the friction pad pressure block 6 maintains a stable direction during movement and does not deviate. The sliding cylinder 7 is slidably connected to the outer side of the sliding rod 11, providing a sliding track for the sliding rod 11 to ensure the smoothness of its movement. A spring 8 is sleeved on the outer side of the sliding cylinder 7, and the two ends of the spring 8 are fixedly connected to the outer side of the sliding cylinder 7 and the friction pad pressure block 6, respectively.Spring 8 acts as a buffer and reset mechanism. After braking ends, the friction pad block 6 automatically resets under the elastic force of spring 8, preparing for the next braking operation. A friction pad 9 is fixedly connected to the outer side of the friction pad block 6. The friction pad 9 is the component that directly contacts the friction material and generates friction. The braking effect is achieved through friction with the friction material, thus stopping the equipment. A through hole 10, adapted to the friction pad block 6, is provided on the inner side of the lever arm 4. The through hole 10 provides space for the movement of the friction pad block 6, allowing it to smoothly move in and out under the drive of the lever arm 4. The friction pad block 6 is connected to the lever arm 4 via a pin. This connection method ensures that the friction pad block 6 can... As the lever arm 4 rotates, it can also move flexibly to a certain extent to better adapt to the braking requirements of the disc. Threaded holes 12 are provided on the inner sides of both the mounting base 1 and the bracket 2. Bolts 13 are threaded onto the inner walls of the threaded holes 12. Through the cooperation of the bolts 13 and the threaded holes 12, a detachable connection between the mounting base 1 and the bracket 2 can be achieved, facilitating installation, disassembly, and maintenance when needed. A connecting rod 14 is fixedly connected to both the output end and the bottom of the cylinder 5. The connecting rod 14 transmits the force of the cylinder 5 to the lever arm 4. The connecting rod 14 and the lever arm 4 are connected by a pin. This connection method ensures effective force transmission and allows the lever arm 4 to rotate flexibly under the action of the cylinder 5, thus achieving the braking function.

[0023] In this embodiment, the drag bracket 2 is slid along the side of the mounting base 1 to a suitable height, and the bolt 13 is threaded into the threaded hole 12 and tightened to connect the mounting base 1 and the bracket 2. The output end of the control cylinder 5 is extended, and the output end of the control cylinder 5 drives one end of the power arm 4 to move upward, so that the ends of the pair of power arms 4 close to the cylinder 5 move away from each other. Using the connection position connected to the fixed block 3 as a fulcrum, the pair of friction plate pressing blocks 6 are driven to move closer to each other. The friction plate pressing blocks 6 drive the friction plates 9 to move closer to each other to clamp the external friction material. The control cylinder 5 drives the output end to reset, and the sliding cylinder 7 slides along the sliding rod 11 under the action of the spring 8 to reset the power arm.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
