Description

Technical Field

[0001] The utility model relates to the field of brake pads, in particular to an anti-slip brake pad. Background Art

[0002] Brake pads are generally composed of steel sheets and friction blocks that are pressed and bonded to each other at high temperatures. During the use of brake pads, the friction blocks will be worn. When worn to a certain extent, the braking effect of the brake pads will deteriorate, and the user needs to observe and replace them. In the Chinese utility model patent with announcement number CN218093993U, an anti-slip brake pad is disclosed. By fixing a warning piece on a steel plate and setting the thickness of the warning piece to be less than that of the friction block, if the thickness of the friction block after wear is close to or equal to the thickness of the warning piece, the user needs to replace the brake pad. The brake pad has a warning function, thereby preventing the user from continuing to use the excessively worn brake pad, and has good safety. The brake pads are all set in the brake drum, which will not be directly exposed to the external field of view. In actual use, we cannot observe the actual wear of the brake pads with the naked eye. Generally, the brake drum needs to be disassembled to see the actual situation, which makes the operation more inconvenient. For this reason, we designed an anti-slip brake pad. Utility Model Content

[0003] In order to solve the technical problem that it is inconvenient to observe the actual wear condition of the brake pad, the utility model provides an anti-slip brake pad.

[0004] The utility model is implemented by the following technical scheme: an anti-slip brake pad, comprising a steel plate, wherein fixing ears are integrally arranged on the left and right sides of the steel plate, an enlarged portion is installed on the upper surface of the steel plate, a friction plate is arranged above the enlarged portion, a thickened portion is arranged on the outer surface of the friction plate, and a plurality of evenly distributed sound absorption holes are opened on the upper surface of the friction plate.

[0005] As a further improvement of the above scheme, a mounting groove is provided on the upper surface of the steel plate, and a plurality of evenly distributed fixing screw holes are provided on the bottom surface of the steel plate. The enlarged portion is placed in the mounting groove, and a plurality of screw holes matching the fixing screw holes are provided on the bottom end of the enlarged portion. The enlarged portion and the steel plate are connected by fixing bolts, the fixing screw holes are countersunk screw holes, and the fixing bolts are countersunk bolts, which facilitate the installation and disassembly of the steel plate and the enlarged portion, and the bottom end of the countersunk bolt is flush with the bottom surface of the steel plate.

[0006] As a further improvement of the above scheme, the shape and size of the enlarged part match the installation groove, and the upper part of the enlarged part is 1-2 cm above the upper surface of the steel plate, which is convenient for the installation and disassembly of the enlarged part. The enlarged part is the same as the friction plate. When the friction plate is severely worn and flush with the surface of the enlarged part, it can perform a braking effect.

[0007] As a further improvement of the above scheme, an embedding groove is provided on the upper end surface of the enlarged part, and a plurality of evenly distributed mounting screw holes are provided upward at the bottom end of the enlarged part. A screw hole is provided at the bottom end of the friction plate, and the bottom end of the friction plate is placed in the embedding groove, and the friction plate and the enlarged part are fixed by mounting bolts. The mounting screw holes are countersunk screw holes, and the mounting bolts are countersunk bolts, and the bottom end of the countersunk bolts contacts the bottom end of the inner wall of the mounting groove, so that when the friction plate is braked, the mounting bolts do not have sufficient clearance to rotate, thereby improving the firmness and facilitating the installation and disassembly of the friction plate.

[0008] As a further improvement of the above scheme, the shape and size of the friction plate match the shape and size of the embedded groove, and the size of the thickened portion is larger than the size of the embedded groove. The bottom end of the thickened portion is in close contact with the upper end surface of the enlarged portion. The thickened portion is used to increase the friction area of ​​the friction plate, thereby improving the braking effect.

[0009] As a further improvement of the above scheme, the sound absorption holes do not pass through the upper and lower sides of the friction plate, and the bottom ends of the sound absorption holes are flush with the upper surface of the enlarged portion, and the top ends of the mounting bolts are below the upper surface of the enlarged portion. The sound absorption holes allow the sound waves generated during friction to penetrate deep into the air intake along these holes and rub against the edge of the holes to convert the sound energy into heat energy, thereby reducing the friction sound generated during braking, making it easier to judge the wear condition of the friction plate based on the different sounds.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model arranges sound-absorbing holes on the friction plate, so that the sound waves generated during friction can go deep into the air intake along these holes and rub against the hole edge to convert the sound energy into heat energy, thereby reducing the friction sound generated during braking, making it easy to judge the wear of the friction plate according to the difference in sound. In combination with the thickened part, the overall friction area remains unchanged and the braking effect is not affected.

[0012] 2. The entire brake pad adopts an independent design. They can be installed and disassembled separately, which is convenient for replacing a certain component above it, improving convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0019] Example:

[0020] Please combine Figure 1-Figure 3 An anti-slip brake pad of the present embodiment includes a steel plate 1, and fixing ears 11 are integrally arranged on the left and right sides of the steel plate 1. An enlarged portion 2 is installed on the upper end surface of the steel plate 1, and a friction plate 3 is arranged above the enlarged portion 2. A thickened portion 4 is arranged on the outer surface of the friction plate 3, and a plurality of evenly distributed sound absorption holes 31 are opened on the upper end surface of the friction plate 3.

[0021] A mounting groove 12 is provided on the upper surface of the steel plate 1, and a plurality of evenly distributed fixing screw holes 23 are provided on the bottom surface of the steel plate 1. The enlarged portion 2 is placed in the mounting groove 12, and a plurality of screw holes matching the fixing screw holes 23 are provided on the bottom end of the enlarged portion 2. The enlarged portion 2 is connected to the steel plate 1 by a fixing bolt 13. The fixing screw hole 23 is a countersunk screw hole, and the fixing bolt 13 is a countersunk bolt, which facilitates the installation and disassembly of the steel plate 1 and the enlarged portion 2, and the bottom end of the countersunk bolt is flush with the bottom surface of the steel plate 1.

[0022] The shape and size of the enlarged portion 2 match the mounting groove 12, and the upper portion of the enlarged portion 2 is 1-2 cm above the upper surface of the steel plate 1, which is convenient for the installation and disassembly of the enlarged portion 2. The enlarged portion 2 is the same as the friction plate 3. When the friction plate 3 is severely worn and flush with the surface of the enlarged portion 2, it can perform a braking effect.

[0023] An embedding groove 21 is provided on the upper end surface of the enlarged portion 2, and a plurality of evenly distributed mounting screw holes 22 are provided upward at the bottom end of the enlarged portion 2. A screw hole is provided at the bottom end of the friction plate 3, and the bottom end of the friction plate 3 is placed in the embedding groove 21, and the friction plate 3 and the enlarged portion 2 are fixed by mounting bolts 24. The mounting screw holes 22 are countersunk screw holes, and the mounting bolts 24 are countersunk bolts, and the bottom end of the countersunk bolts contacts the bottom end of the inner wall of the mounting groove 12. This ensures that when the friction plate 3 is braked, the mounting bolts 24 do not have sufficient clearance to rotate, thereby improving the firmness and facilitating the installation and disassembly of the friction plate 3.

[0024] The shape and size of the friction plate 3 match those of the embedding groove 21, and the size of the thickened portion 4 is larger than that of the embedding groove 21. The bottom end of the thickened portion 4 is in close contact with the upper end surface of the enlarged portion 2. The thickened portion 4 is used to increase the friction area of ​​the friction plate 3, thereby improving the braking effect.

[0025] The sound absorption holes 31 do not penetrate the upper and lower sides of the friction plate 3, and the bottom ends of the sound absorption holes 31 are flush with the upper surface of the enlarged portion 2, and the top ends of the mounting bolts 24 are below the upper surface of the enlarged portion 2. The sound absorption holes 31 allow the sound waves generated during friction to penetrate into the air intake along these holes and rub against the edges of the holes to convert the sound energy into heat energy, thereby reducing the friction sound generated during braking, making it easier to judge the wear condition of the friction plate 3 based on the different sounds.

[0026] The implementation principle of an anti-slip brake pad in the embodiment of the present application is as follows: in actual use, by setting a sound absorption hole 31 above the friction plate 3, when braking, the friction of the friction plate 3 will produce a certain sound, and the sound absorption hole 31 allows the sound waves generated during friction to penetrate into the air intake along these holes and rub against the hole edge to convert the sound energy into heat energy, thereby reducing the friction sound generated during braking. When the friction plate 3 is worn to a greater extent, the depth of the sound absorption hole 31 will gradually change, resulting in a different sound. When the friction plate 3 is completely worn, that is, the enlarged portion 2 will participate in the braking process, and the sound at this time will also be completely different. During detection, the condition of the brake pad can be roughly judged according to the condition of the sound, and then it can be replaced;

[0027] By providing sound-absorbing holes 31 on the friction plate 3, the sound waves generated during friction can go deep into the air intake along these holes and rub against the hole edges to convert the sound energy into heat energy, thereby reducing the friction sound generated during braking, making it easier to judge the wear of the friction plate 3 according to the sound difference. In combination with the thickened portion 4, the overall friction area remains unchanged, and the braking effect is not affected.

[0028] The entire brake pad adopts an independent design. They can be installed and removed individually, making it easy to replace a component above them, thereby improving convenience.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
