Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, specifically a brake disc with integrated wear indicator grooves. Background Technology

[0002] Brake discs are the core rotating components in braking systems of automobiles, rail transportation, and industrial machinery. They are typically made of cast iron or alloy steel, are disc-shaped, and are bolted to the wheel or drive shaft. Their working principle is as follows: during braking, brake pads (friction pads) clamp the sides of the brake disc under hydraulic or pneumatic pressure. Through friction, kinetic energy is converted into heat energy and dissipated, thus slowing down and stopping the vehicle or equipment. As the core component of the braking system, the wear condition of the brake disc directly affects the operational safety of the equipment.

[0003] According to Chinese Patent CN221647471U, a wind turbine brake disc wear detection device relates to the field of brake disc wear detection technology. This device includes a wind turbine brake disc body, with a support plate on the outer side of the body. Multiple rotating rods are rotatably connected inside the support plate, and a circular roller is fixedly connected to the outer side of each rotating rod. A wiping belt is provided on the outer side of the circular roller, and a wiping plate is provided on one side of the wiping belt. This device allows for quick release of the collection box, enabling rapid disassembly. When installation is required, the collection box is pressed along a groove until a second protrusion aligns with a slot on one side of the first protrusion. At this point, the second protrusion, under the elastic force of a first spring, quickly engages with the first protrusion. This structure facilitates rapid disassembly of the collection box, is simple in design, easy to operate, and saves time and manpower.

[0004] The aforementioned device triggers an alarm by contacting the brake disc with a contact probe, but it cannot display specific wear values, and the contact probe gradually wears down with prolonged contact with the brake disc, requiring frequent replacement. Therefore, we provide a brake disc with an integrated wear indicator groove. Utility Model Content

[0005] The purpose of this invention is to provide a brake disc with an integrated wear indicator groove to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a brake disc with integrated wear indicator grooves, comprising: a brake disc body; Wear indicator grooves are formed on the front side of the brake disc body; A limiting sensor plate is fixedly connected to the inner surface of the wear indicator groove; And an operating component disposed on the right side of the brake disc body; the operating component includes a friction part disposed on the right side of the brake disc body, and the friction part is connected to an indicator part.

[0007] Preferably, the friction part includes a mounting bracket disposed on the right side of the brake disc body. An adjusting rod extends through the front of the mounting bracket. A connecting plate is fixedly connected to the inner end of the adjusting rod. The side end of the connecting plate extends through a limiting groove and is fixedly connected to a movable block. The limiting groove is located on the side of the fixed block. The front of the fixed block is fixedly connected to the inner wall of the front of the mounting bracket. The front end of the movable block is inserted into the inner surface of the fixed block. A fixing frame is fixedly connected to the back of the movable block. A friction roller is rotatably connected to the inner surface of the fixing frame via a shaft. The front of the fixing frame is fixedly connected to the inner wall of the front of the mounting bracket via an elastic sheet. A spring is fixedly connected to the front of the connecting plate. The end of the spring away from the connecting plate is fixedly connected to the inner wall of the front of the mounting bracket.

[0008] Preferably, the indicating part includes a linkage plate fixedly connected to the outer end of the adjusting rod. A movable rod is fixedly connected to the back of the right end of the linkage plate. The end of the movable rod away from the linkage plate passes through the front of the mounting frame and is fixedly connected to a contact block. An indicating needle is fixedly connected to the outer wall of the inner end of the movable rod. A scale plate is provided on the right side of the indicating needle. The right side of the scale plate is engaged with the inner surface of the fixing groove, which is opened on the inner right side of the mounting frame.

[0009] Preferably, the inner end of the adjusting rod is configured to slide through the front of the mounting bracket. When the brake disc wears and becomes thinner, the spring pushes the connecting plate to cause the adjusting rod to slide.

[0010] Preferably, the outer surface of the friction roller is in contact with the surface of the brake disc body. Under the preload of the elastic sheet and spring, the friction roller always adheres to the surface and gradually moves as the wear thickness of the brake disc body decreases, triggering subsequent indication actions.

[0011] Preferably, the inner end of the movable rod is configured to slide through the front of the mounting bracket, and the position of the indicator needle is changed by adjusting the rod through the limiting plate.

[0012] Preferably, the number of contact blocks is set to two, and the two contact blocks are respectively fixedly connected to the inner ends of two moving rods and are symmetrical front and back. By moving the two contact blocks, different wear areas of the brake disc can be indicated simultaneously.

[0013] Compared with the prior art, the present invention provides a brake disc with integrated wear indicator grooves, which has the following advantages: The brake disc with integrated wear indicator groove has an adjusting rod that maintains an inward pushing trend under the action of a spring, which drives the connecting plate, movable block and fixed frame to move, so that the friction roller is in close contact with the surface of the brake disc body. As the brake disc body wears and becomes thinner, the mounting frame drives the friction roller to gradually move towards the surface of the brake disc body under the spring force. At the same time, the wear indicator groove is used as a reference scale to intuitively reflect the change in the thickness of the brake disc body. The limit sensor is embedded in the groove. As the brake disc body wears and becomes thinner, when the friction roller contacts the limit sensor, an early warning will be triggered.

[0014] This brake disc with integrated wear indicator grooves, when the adjusting rod moves, drives the moving rod to move synchronously through the linkage plate. The moving rod drives the contact block and indicator needle to move and gradually approach each other, so that the indicator needle slides along the scale plate, thereby displaying the wear value in real time. The condition of the brake disc body can be quickly judged without disassembly, improving maintenance efficiency. Attached Figure Description

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.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Example 1: The brake disc with integrated wear indicator groove provided by this utility model, such as Figures 1 to 5 As shown: A brake disc with integrated wear indicator grooves includes: a brake disc body 1; Wear indicator groove 3 is provided on the front of the brake disc body 1; A limiting sensor 4 is fixedly connected to the inner surface of the wear indicator groove 3; And an operating component 2 located on the right side of the brake disc body 1; the operating component 2 includes a friction part 21 located on the right side of the brake disc body 1, and an indicator part 22 connected to the friction part 21.

[0020] The friction part 21 includes a mounting bracket 211 located on the right side of the brake disc body 1. An adjusting rod 212 extends through the front of the mounting bracket 211. A connecting plate 213 is fixedly connected to the inner end of the adjusting rod 212. The side end of the connecting plate 213 extends through a limiting groove 215 and is fixedly connected to a movable block 216. The limiting groove 215 is located on the side of the fixed block 214. The front of the fixed block 214 is fixedly connected to the inner wall of the front of the mounting bracket 211. The front end of the movable block 216 is inserted into the inner surface of the fixed block 214. A fixing frame 217 is fixedly connected to the back of the movable block 216. A friction roller 210 is rotatably connected to the inner surface of the fixing frame 217 via a shaft. The front of the fixing frame 217 is fixedly connected to the inner wall of the front of the mounting bracket 211 via an elastic sheet 219. A spring 218 is fixedly connected to the front of the connecting plate 213. The end of the spring 218 away from the connecting plate 213 is fixedly connected to the inner wall of the front of the mounting bracket 211.

[0021] In this embodiment, the inner end of the adjusting rod 212 is configured to slide through the front of the mounting bracket 211. When the brake disc body 1 wears thinner, the elastic force of the spring 218 pushes the connecting plate 213 to drive the adjusting rod 212 to slide.

[0022] Furthermore, the outer surface of the friction roller 210 is in contact with the surface of the brake disc body 1. Under the preload of the elastic sheet 219 and the spring 218, the friction roller 210 always adheres to its surface and gradually moves as the wear thickness of the brake disc body 1 decreases, triggering subsequent indication actions.

[0023] Example 2: Based on Example 1, the brake disc with integrated wear indicator groove provided by this utility model, such as... Figures 1 to 5 As shown: The indicator part 22 includes a linkage plate 221 fixedly connected to the outer end of the adjusting rod 212. A moving rod 222 is fixedly connected to the back of the right end of the linkage plate 221. The end of the moving rod 222 away from the linkage plate 221 passes through the front of the mounting bracket 211 and is fixedly connected to a contact block 223. An indicator needle 224 is fixedly connected to the outer wall of the inner end of the moving rod 222. A scale plate 225 is provided on the right side of the indicator needle 224. The right side of the scale plate 225 is engaged with the inner surface of the fixing groove 226, which is opened on the inner right side of the mounting bracket 211.

[0024] In this embodiment, the inner end of the moving rod 222 is configured to slide through the front of the mounting bracket 211, and the position of the indicator needle 224 is changed by the adjusting rod 212 through the limiting plate 211.

[0025] Furthermore, the number of contact blocks 223 is set to two. The two contact blocks 223 are fixedly connected to the inner ends of the two moving rods 222 respectively and are symmetrical front and back. By moving the two contact blocks 223, different wear areas of the brake disc can be indicated at the same time.

[0026] In actual operation, when this device is used, the adjusting rod 212 maintains an inward pushing trend under the action of the spring 218, and drives the connecting plate 213, the movable block 216 and the fixed frame 217 to move, so that the friction roller 210 is tightly attached to the surface of the brake disc body 1. As the brake disc body 1 wears and becomes thinner, the mounting frame 211 drives the friction roller 210 to gradually move towards the surface of the brake disc body 1 under the push of the spring 218. At the same time, the wear indicator groove 3 is used as a reference scale to intuitively reflect the change in the thickness of the brake disc body 1. The limit sensing piece 4 is embedded in the groove. As the brake disc body 1 wears and becomes thinner, when the friction roller 210 contacts the limit sensing piece 4, an early warning will be triggered.

[0027] When the adjusting rod 212 moves, the moving rod 222 moves synchronously through the linkage plate 221. The moving rod 222 drives the contact block 223 and the indicator needle 224 to move and gradually approach each other, so that the indicator needle 224 slides along the scale plate 225, thereby displaying the wear value in real time. The condition of the brake disc body 1 can be quickly judged without disassembly, improving maintenance efficiency.
