Technical Field
[0001] This utility model relates to the field of split brake disc technology, and in particular to a steel plate split brake disc. Background Technology
[0002] A brake disc is a circular disc that connects to the car's wheel hub. When braking, the brake caliper inside the car engages with the surface of the brake disc to brake the wheel hub. A split brake disc separates the center disc connected to the wheel hub and the brake disc into two parts for easier maintenance and replacement later.
[0003] When using a split brake disc, the center disc is usually placed on the surface of the brake disc, and then bolts are passed through the screw holes on the surface of the center disc and the surface of the brake disc and secured with nuts. However, with long-term use of the brake disc, the connection between the center disc and the brake disc may loosen, causing the connection between the center disc and the brake disc to become unstable and shake, affecting the normal use of the brake disc. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that, in the use of split brake discs, the center disc is usually placed on the surface of the brake disc, and then bolts are used to pass through the screw holes on the surface of the center disc and the surface of the brake disc and fixed with nuts. However, after long-term use of the brake disc, the connection between the center disc and the brake disc may loosen, resulting in an unstable connection between the center disc and the brake disc and causing shaking, which affects the normal use of the brake disc. Therefore, a steel plate split brake disc is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel plate split brake disc, comprising a brake disc and a center disc, wherein the outer surfaces of the brake disc and the center disc are respectively provided with a plurality of first mounting holes and second mounting holes, the interior of the brake disc is provided with a plurality of air ducts, and the outer surface of the brake disc is provided with a reinforcing device, the reinforcing device comprising two semi-circular clamps, the top of the inner wall of the semi-circular clamps being provided with a plurality of grooves, the inner wall of the semi-circular clamps being slidably inserted with a first bolt, the outer surface of the first bolt being threadedly connected with a first nut, and the outer surface of the brake disc being provided with two insertion holes.
[0006] The effect achieved by the above components is as follows: When connecting the center disc and the brake disc using the reinforcement device, first place the center disc on the outer surface of the brake disc and align the second mounting hole on the surface of the center disc with the first mounting hole on the surface of the brake disc. Then, use bolts to pass through the first and second mounting holes, and use nuts to fix the center disc and brake disc by placing them on the outer surface of the bolts. Next, insert one end of a semi-circular clamp into a fan-shaped groove on the outer surface of the brake disc, so that the head of each bolt is located in the groove of the semi-circular clamp. Finally, use the first bolt to pass through the outer surface of the brake disc on the outer ring of the brake disc. Near the insertion hole on one side of the semi-circular clamp, use the first nut to fit over the outer surface of the first bolt on the inner ring of the brake disc and rotate the first nut or the first bolt to press one side of the first nut against the inner ring of the brake disc, thus fixing the semi-circular clamp to the outer surface of the brake disc. Then, fix the other semi-circular clamp to the outer surface of the brake disc in the same way. By fixing the two semi-circular clamps to the outer surface of the brake disc and placing the bolt head of the fixing center disc and the brake disc inside the groove of the semi-circular clamp, the position of the bolt is fixed to prevent the bolt from loosening during the use of the brake disc as much as possible, thereby increasing the stability of the brake disc during use.
[0007] Preferably, rectangular pieces are fixedly connected to the left and right sides of the inner wall of the groove, and the rectangular pieces are springs made of semi-metallic friction material.
[0008] The effect achieved by the above components is that by setting a rectangular piece of semi-metallic friction material, the bolt heads of the fixed center disc and brake disc can make more full contact with the inner wall of the groove when they are inside the groove, further increasing the stability of the semi-circular clamp fixing the bolts.
[0009] Preferably, a plurality of rectangular holes are provided at one end of the outer surface of the semicircular clamp, and the rectangular holes are distributed circumferentially on the outer surface of the semicircular clamp.
[0010] The effect achieved by the above components is that when one end of the semicircular clamp is inserted into the inside of the fan-shaped groove, the rectangular hole on the outer surface will be connected with the air passage inside the brake disc, minimizing the impact of the semicircular clamp on the heat dissipation effect of the air passage during the use of the brake disc.
[0011] Preferably, one end of the first bolt is fixedly connected with a plurality of protrusions, which are distributed circumferentially on the outer surface of the first bolt.
[0012] The effect achieved by the above-mentioned components is that the protrusion on the outer surface of the first bolt makes it easier to grip and rotate the first bolt without slipping.
[0013] Preferably, an L-shaped groove is formed on one side of the outer surface of the semicircular clamp, and the L-shaped groove is located on the side of the outer surface of the semicircular clamp away from the groove.
[0014] The effect achieved by the above components is that when the reinforcement device needs to be disassembled, tools or fingers can be used to pull the semicircular clamp by hooking it at the L-shaped groove on the outer surface of the semicircular clamp, making it easier to pull one end of the semicircular clamp out from the inside of the fan-shaped groove.
[0015] Preferably, an annular strip is fixedly connected to the outer surface of the brake disc near the fan-shaped groove, and the diameter of the annular strip is larger than the diameter of the central disc.
[0016] The effect achieved by the above components is that when the center disc is placed on the outer surface of the brake disc for connection, the outer edge of the center disc can be attached to the inner wall of the annular strip, and the annular strip can fix the relative position between the center disc and the brake disc to facilitate connection.
[0017] Preferably, the outer surface of the brake disc is provided with an auxiliary device, the auxiliary device including a spring, the outer surface of the spring having a positioning hole, and two rectangular blocks fixedly connected to one side of the spring.
[0018] The effect achieved by the above components is as follows: when the semicircular clamp of the reinforcement device is fixed on the outer surface of the brake disc, the positioning hole of a spring piece can be fitted onto the outer surface of the first bolt that fixes the semicircular clamp, so that the two rectangular blocks are inserted into the two air channels on the left and right sides of the first bolt. Then, the first nut is fitted onto the outer surface of the first bolt and the first nut is rotated to push the spring piece to move on the outer surface of the first bolt, pressing one side of the spring piece against the inner ring of the brake disc. By setting the spring piece and the rectangular blocks, the position of the semicircular clamp and the brake disc is more stable and less prone to loosening when fixed by the first nut and the first bolt.
[0019] Preferably, a plurality of protruding strips are fixedly connected to one side of the rectangular block, and the protruding strips are linearly distributed on one side of the outer surface of the rectangular block.
[0020] The effect achieved by the above components is that by setting the convex strip, the friction between the outer surface of the rectangular block and the inner wall of the air duct can be increased, making the rectangular block less likely to shake or loosen inside the air duct.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a reinforcement device, after connecting the center disc and the brake disc, two semi-circular clamps are fixed to the outer surface of the brake disc. The bolt head that fixes the center disc and the brake disc is placed inside the groove of the semi-circular clamp to fix the position of the bolt as much as possible to prevent the bolt from loosening during the use of the brake disc, which would cause the brake disc and the center disc to shake.

[0031] Example 1, such as Figure 1-7As shown, a steel plate split brake disc includes a brake disc 1 and a center disc 4. The outer surfaces of the brake disc 1 and the center disc 4 are respectively provided with a plurality of first mounting holes 5 and second mounting holes 6. The brake disc 1 has a plurality of air ducts 7 inside. A reinforcing device 2 is provided on the outer surface of the brake disc 1. The reinforcing device 2 includes two semi-circular clamps 22. The top of the inner wall of each semi-circular clamp 22 has a plurality of grooves 26. A first bolt 23 is slidably inserted into the inner wall of each semi-circular clamp 22. A first nut 25 is threaded onto the outer surface of the first bolt 23. Two insertion holes 211 are provided on the outer surface of the brake disc 1. When connecting the center disc 4 to the brake disc 1 using the reinforcing device 2, the center disc 4 is first placed on the outer surface of the brake disc 1, and the second mounting holes 6 on the surface of the center disc 4 are aligned with the first mounting holes 5 on the surface of the brake disc 1. Then, bolts are passed through the first mounting holes 5 and the second mounting holes 6, and nuts are fitted onto the outer surface of the bolts to fix the position of the center disc 4 and the brake disc 1. Next, insert one end of a semicircular clamp 22 into a fan-shaped groove 21 on the outer surface of the brake disc 1, so that the head of each bolt is located inside the groove 26 of the semicircular clamp 22. Then, use the first bolt 23 to pass through the insertion hole 211 on the outer surface of the brake disc 1 near the semicircular clamp 22. Then, use the first nut 25 to fit on the outer surface of the first bolt 23 at the inner ring of the brake disc 1 and rotate the first nut 25 or the first bolt 23 to press one side of the first nut 25 against the inner ring of the brake disc 1 to fix the semicircular clamp 22 to the outer surface of the brake disc 1. Then, fix the other semicircular clamp 22 to the outer surface of the brake disc 1 in the same way. By fixing the two semicircular clamps 22 to the outer surface of the brake disc 1 and making the fixing center disc 4 and the bolt head of the brake disc 1 inside the groove 26 of the semicircular clamp 22, the position of the bolts is fixed to prevent the bolts from loosening during the use of the brake disc as much as possible, and to increase the stability of the brake disc during use.
[0032] Reference Figure 1-3 As shown in this embodiment: rectangular pieces 27 are fixedly connected to the left and right sides of the inner wall of the groove 26. The rectangular pieces 27 are thin sheets of semi-metallic friction material. By setting the rectangular pieces 27 of semi-metallic friction material, the bolt heads of the fixed center disc 4 and brake disc 1 are in full contact with the inner wall of the groove 26 when they are inside the groove 26, which further increases the stability of the semi-circular clamp for fixing the bolts. Several rectangular holes 29 are opened at one end of the outer surface of the semi-circular clamp 22. The rectangular holes 29 are distributed in a circle on the outer surface of the semi-circular clamp 22. When one end of the semi-circular clamp 22 is inserted into the inside of the fan-shaped groove 21, the rectangular holes 29 on the outer surface will be connected to the air duct 7 inside the brake disc 1, so as to avoid the semi-circular clamp 22 affecting the heat dissipation effect of the air duct 7 when the brake disc is in use. Several protrusions 24 are fixedly connected to one end of the first bolt 23. The protrusions 24 are distributed in a circle on the outer surface of the first bolt 23. Holding the protrusions 24 on the outer surface of the first bolt 23 makes it easier to pinch and rotate the first bolt 23 and prevents the hand from slipping.
[0033] Reference Figure 1-3 As shown in this embodiment: an L-shaped groove 210 is provided on one side of the outer surface of the semicircular clamp 22. The L-shaped groove 210 is located on the side of the outer surface of the semicircular clamp 22 away from the groove 26. When the reinforcing device 2 needs to be disassembled, a tool or a finger hook can be used to pull the semicircular clamp 22 at the L-shaped groove 210 on the outer surface of the semicircular clamp 22. This makes it easier to pull one end of the semicircular clamp 22 out from the inside of the fan-shaped groove 21. An annular strip 28 is fixedly connected to the side of the outer surface of the brake disc 1 near the fan-shaped groove 21. The diameter of the annular strip 28 is larger than the diameter of the center disc 4. When the center disc 4 is placed on the outer surface of the brake disc 1 for connection, the outer edge of the center disc 4 can be attached to the inner wall of the annular strip 28. The annular strip 28 fixes the relative position between the center disc 4 and the brake disc 1 for easy connection.
[0034] Reference Figure 1 , Figure 2 and Figure 4 As shown in this embodiment: an auxiliary device 3 is provided on the outer surface of the brake disc 1. The auxiliary device 3 includes a spring 31. A positioning hole 33 is opened on the outer surface of the spring 31. Two rectangular blocks 32 are fixedly connected to one side of the spring 31. When the semicircular clamp 22 of the reinforcing device 2 is fixed to the outer surface of the brake disc 1, the positioning hole 33 of one spring 31 can be fitted onto the outer surface of the first bolt 23 that fixes the semicircular clamp 22, so that the two rectangular blocks 32 are inserted into the two air ducts 7 on the left and right sides of the first bolt 23. Then, the first nut 25 is fitted onto the outer surface of the first bolt 23 and the first nut 25 is rotated to push... The movable spring piece 31 moves on the outer surface of the first bolt 23, pressing one side of the spring piece 31 against the inner ring of the brake disc 1. By setting the spring piece 31 and the rectangular block 32, the position of the semicircular clamp 22 and the brake disc 1 is fixed more stably and less prone to loosening by the first nut 25 and the first bolt 23. Several protrusions 34 are fixedly connected to one side of the rectangular block 32. The protrusions 34 are linearly distributed on one side of the outer surface of the rectangular block 32. By setting the protrusions 34, the friction between the outer surface of the rectangular block 32 and the inner wall of the air duct 7 can be increased, making it less likely for the rectangular block 32 to shake or loosen inside the air duct 7.
[0035] Working principle: When connecting the center disc 4 of the split brake disc to the brake disc 1, first place the outer surface of the center disc 4 against the inner wall of the annular strip 28 on the outer surface of the brake disc 1, aligning the second mounting hole 6 on the surface of the center disc 4 with the first mounting hole 5 on the surface of the brake disc 1. Then, use bolts to pass through the first mounting hole 5 and the second mounting hole 6, and use nuts to fix the position of the center disc 4 and the brake disc 1 by putting them on the outer surface of the bolts. Then, insert one end of a semi-circular clamp 22 with a rectangular hole 29 into the inside of the fan-shaped groove 21 on the outer surface of the brake disc 1, so that the head of each bolt is located inside the groove 26 of the semi-circular clamp 22. Then, use the first bolt 23 to pass through the insertion hole 211 on the outer surface of the brake disc 1 near the semi-circular clamp 22 on the outer ring of the brake disc 1, and then insert a... The positioning hole 33 of the spring piece 31 is fitted onto the outer surface of the first bolt 23, so that the two rectangular blocks 32 are inserted into the two air ducts 7 on the left and right sides of the first bolt 23. Then, the first nut 25 is fitted onto the outer surface of the first bolt 23 at the inner ring of the brake disc 1, and the first nut 25 is rotated to push the spring piece 31 to move on the outer surface of the first bolt 23, pressing one side of the spring piece 31 against the inner ring of the brake disc 1, and fixing the semi-circular clamp 22 to the outer surface of the brake disc 1. Then, the other semi-circular clamp 22 is fixed to the outer surface of the brake disc 1 in the same way. By fixing the center disc 4 and the bolt head of the brake disc 1 inside the groove 26 of the semi-circular clamp 22, the position of the bolt is fixed as much as possible to avoid the bolt from loosening during the use of the brake disc, which would cause the brake disc 1 and the center disc 4 to shake.
