Description

Technical Field

[0001] This utility model relates to the field of brake friction pad replacement technology, and in particular to a quick brake friction pad replacement structure. Background Technology

[0002] A brake is a device that slows down, stops, or keeps a moving part (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down moving parts in machinery and is commonly known as a brake or brake.

[0003] In the existing technology, brakes are often put into use on the market after the surface is inspected by the naked eye for defects, and there is a lack of testing equipment for brakes;

[0004] An existing patent (publication number: CN214951001U) discloses a manual brake testing device, relating to the field of brakes. It includes a mounting plate with a positioning component and a testing component. To facilitate brake testing, the mounting plate of this device is equipped with these components. The positioning component positions the brake in parallel, while the dial indicator in the testing component is located on the friction pad that presses against the outer ring of the brake. When the drive unit drives the brake mounting platform and the brake to rotate, the dial indicator determines the runout and perpendicularity of the outer circle of the brake friction pad. The brake mounting platform and the support platform are detachably connected, allowing for easy replacement of different sized brake mounting platforms according to the brake model and size.

[0005] To address the aforementioned issues, existing patents offer solutions. However, these solutions have certain limitations in practice. When replacing brake pads, most methods involve disassembly using a flathead screwdriver, which can easily damage the brake disc surface. When removing the brake from the brake disc surface using a screwdriver, the piston inside the brake is prone to reverting to its original position. This necessitates adjustment using tools after replacing the brake pads, thus reducing the efficiency of brake pad replacement.

[0006] To address this, a quick-change structure for brake friction pads is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a quick-change structure for brake friction pads, which solves the problem that in the current process of replacing brake friction pads, most of them are disassembled with a flathead screwdriver, which can easily damage the surface of the brake disc. When the brake is removed from the surface of the brake disc with a screw, the piston inside the brake is prone to return to its original position, so that after replacing the friction pads, it is necessary to adjust them with tools, thereby reducing the efficiency of replacing friction pads.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a quick-change structure for brake friction pads, including a brake disc, on the surface of which a brake body and two friction pad bodies are provided, an auxiliary mechanism is provided between opposite sides of the two friction pad bodies, and a limit mechanism is provided inside the brake body.

[0009] The limiting mechanism includes four limiting pads, two limiting plates, two adjusting blocks, three limiting posts, and two support posts. The side of the limiting pad closest to the limiting plate is in close contact with the limiting plate. The opposite sides of the two limiting pads are in close contact with the top and bottom of the brake body, respectively. The side of the limiting plate closest to the adjusting block is in close contact with the adjusting block. The surface of the limiting post is slidably connected to the inside of the adjusting block. The rear side of the support post is fixedly connected to the front side of the adjusting block.

[0010] Preferably, the auxiliary mechanism includes two auxiliary plates disposed at both the top and bottom of the brake disc, with the side of the auxiliary plate closest to the friction pad body in contact with the friction pad body.

[0011] Preferably, a mounting block is fixedly connected to the bottom of the top auxiliary plate, and a fixing sleeve is fixedly connected to the surface of the mounting block.

[0012] Preferably, the fixed sleeve is internally threaded with a rotating bracket, and the mounting block is fixedly connected to a connecting bend bracket on the side away from the brake disc.

[0013] Preferably, two telescopic sleeves are fixedly connected between the two auxiliary plates on opposite sides, and protective pads are fixedly connected to the opposite sides of the two auxiliary plates.

[0014] Preferably, the adjusting block is internally threaded with four screws, the tops of which pass through the limiting plate and extend into the interior of the limiting pad.

[0015] Preferably, the surface of the connecting bend is rotatably connected to a threaded sleeve, the inside of the threaded sleeve is threadedly connected to a threaded post, and the surface of the threaded post is fixedly connected to a replacement bracket.

[0016] Preferably, the surface of the replacement frame is slidably connected to two rotating sleeves, and each of the two rotating sleeves is rotatably connected to a handle on its opposite side. The surface of the handle is threadedly connected to the inside of the replacement frame, and the surface of the support column is fixedly connected to the inside of the rotating sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application enables the handle to drive the support column for adjustment via the rotating sleeve, thereby facilitating the limiting and fixing of the adjusting block, and enabling the limiting plate to limit the brake body piston via the limiting pad, thereby preventing the brake body piston from returning to its original position.

[0019] 2. In this application, the threaded sleeve drives the mounting block to move via the threaded column and the connecting bending frame. The mounting block then drives the auxiliary plate to move to the opposite side of the two friction pad bodies via the rotating frame and the fixed sleeve. By rotating the rotating frame, the auxiliary plate is disassembled under the limit of the telescopic sleeve. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A quick-change structure for brake friction pads includes a brake disc 1, a brake body 2 and two friction pad bodies 5 are disposed on the surface of the brake disc 1, an auxiliary mechanism 6 is disposed between opposite sides of the two friction pad bodies 5, and a limit mechanism 3 is disposed inside the brake body 2.

[0030] The limiting mechanism 3 includes four limiting pads 301, two limiting plates 302, two adjusting blocks 303, three limiting posts 304, and two support posts 305. The side of the limiting pad 301 closest to the limiting plate 302 is in close contact with the limiting plate 302. The opposite sides of the two limiting pads 301 are in close contact with the top and bottom of the brake body 2, respectively. The side of the limiting plate 302 closest to the adjusting block 303 is in close contact with the adjusting block 303. The surface of the limiting post 304 is slidably connected to the inside of the adjusting block 303. The rear side of the support post 305 is fixedly connected to the front side of the adjusting block 303.

[0031] In this embodiment: by making the surface of the limiting post 304 slide in connection with the interior of the adjusting block 303, the supporting post 305 can easily move and adjust the adjusting block 303 on the surface of the limiting post 304. The adjusting block 303 moves the limiting pad 301 to the interior of the brake body 2 through the limiting plate 302, so that the side of the limiting pad 301 close to the limiting plate 302 is in close contact with the limiting plate 302. This makes it easy for the limiting plate 302 to limit the piston of the brake body 2 through the limiting pad 301, thereby preventing the piston of the brake body 2 from returning to its original position.

[0032] Specifically, such as Figure 2 , Figure 3 As shown, the auxiliary mechanism 6 includes two auxiliary plates 601 provided at the top and bottom of the brake disc 1. The auxiliary plate 601 is in contact with the friction plate body 5 on the side closest to the friction plate body 5.

[0033] Specifically, such as Figure 3 As shown, a mounting block 602 is fixedly connected to the bottom of the top auxiliary plate 601, and a fixing sleeve 604 is fixedly connected to the surface of the mounting block 602.

[0034] Specifically, such as Figure 3 As shown, the fixed sleeve 604 has a rotating bracket 605 connected to its internal thread, and the mounting block 602 has a connecting bend bracket 603 fixedly connected to the side away from the brake disc 1.

[0035] In this embodiment: by connecting the surface of the rotating frame 605 with the internal thread of the fixed sleeve 604, the fixed sleeve 604 can be easily moved by the rotating frame 605 to move the two auxiliary plates 601, so that the side of the auxiliary plate 601 close to the friction plate body 5 contacts the friction plate body 5, thereby facilitating the disassembly of the friction plate body 5 by the auxiliary plate 601, achieving the effect of facilitating the disassembly of the friction plate body 5.

[0036] Specifically, such as Figure 3 As shown, two telescopic sleeves 10 are fixedly connected between the two auxiliary plates 601 on opposite sides, and protective pads 9 are fixedly connected to the opposite sides of the two auxiliary plates 601.

[0037] Specifically, such as Figure 5 As shown, the internal thread of the adjusting block 303 is connected to four screws 11, the top of which passes through the limiting plate 302 and extends into the interior of the limiting pad 301.

[0038] In this embodiment: by fixing the auxiliary plate 601 to the side of the protective pad 9 close to the auxiliary plate 601, the protective pad 9 can easily limit and protect the auxiliary plate 601, and the inside of the adjusting block 303 can be threadedly connected to the surface of the screw 11, thereby making it easy for the adjusting block 303 to fix the limiting pad 301 through the screw 11, thus achieving the effect of fixing the limiting pad 301.

[0039] Specifically, such as Figure 6 As shown, a threaded sleeve 7 is rotatably connected to the surface of the connecting bending frame 603, a threaded post 8 is threadedly connected inside the threaded sleeve 7, and a replacement frame 12 is fixedly connected to the surface of the threaded post 8.

[0040] Specifically, such as Figure 6 As shown, the surface of the replacement frame 12 is slidably connected to two rotating sleeves 13. Each of the two rotating sleeves 13 is rotatably connected to a handle 4 on its opposite side. The surface of the handle 4 is threadedly connected to the inside of the replacement frame 12, and the surface of the support column 305 is fixedly connected to the inside of the rotating sleeve 13.

[0041] In this embodiment: by connecting the surface of the threaded post 8 with the internal thread of the threaded sleeve 7, the threaded sleeve 7 can be easily moved by the threaded post 8 to drive the connecting bending frame 603 to move, and the interior of the rotating sleeve 13 can be slidably connected with the surface of the replacement frame 12, thereby making it easy for the handle 4 to drive the support post 305 to move by the rotating sleeve 13, thus achieving the effect of limiting the position of the support post 305.

[0042] Working principle: When replacing the friction pad body 5, first disassemble the brake body 2, so that the replacement frame 12 moves the adjusting block 303 and the limiting plate 302 into the brake body 2 via the support column 305, so that the side of the limiting pad 301 near the limiting plate 302 is in close contact with the limiting plate 302. Rotate the handle 4, so that the handle 4 drives the support column 305 to adjust via the rotating sleeve 13, thereby facilitating the limiting and fixing of the adjusting block 303. The limiting plate 302 limits the piston of the brake body 2 via the limiting pad 301, thereby preventing the piston of the brake body 2 from returning to its original position. Then rotate the threaded sleeve 7, so that the threaded sleeve 7 drives the mounting block 602 via the connecting bending frame 603 through the threaded column 8. The installation block 602 moves the auxiliary plate 601 to the opposite side of the two friction pad bodies 5 via the rotating frame 605 and the fixed sleeve 604. By rotating the rotating frame 605, the auxiliary plate 601 is driven to disassemble the friction pad body 5 under the limit of the telescopic sleeve 10. This facilitates the protection of the brake disc 1 surface and solves the problem that in the current process of replacing brake friction pads, most of the disassembly is done with a flathead screwdriver, which is easy to damage the surface of the brake disc 1. When the brake is removed from the surface of the brake disc 1 by the screw 11, the piston inside the brake is prone to return to its original position, which means that after replacing the friction pads, it is necessary to adjust them with tools, thus reducing the efficiency of replacing friction pads.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
