Description

Technical Field

[0001] The utility model relates to the field of disc brakes, in particular to a disc brake assembly. Background Art

[0002] The rotating element in the disc brake friction pair is a metal disc that works on the end face, called a brake disc. The friction element clamps the brake disc from both sides to produce braking. The fixed element has various structural forms. Disc brakes can be roughly divided into two types: caliper disc type and full disc type. Disc brakes are hydraulic, controlled by hydraulics. The main components include brake discs, slave cylinders, brake calipers, oil pipes, etc. Disc brakes have fast heat dissipation, light weight, simple structure, and easy adjustment. Especially under high load, they have good high temperature resistance, stable braking effect, and are not afraid of mud and water invasion. When driving in winter and under harsh road conditions, many cars use disc brakes with flat brake discs, perforated brake discs, and scored brake discs. Among them, the scored brake discs have better braking effect and ventilation and heat dissipation capabilities.

[0003] However, the disc brakes currently on the market have poor stability during use, resulting in poor contact between the brake disc and the caliper. In addition, after long-term use, the temperature of the brake disc rises rapidly, and the brake disc is deformed and damaged due to excessive temperature, which reduces the service life.

[0004] Therefore, it is necessary to provide a disc brake assembly to solve the above technical problems. Utility Model Content

[0005] The utility model provides a disc brake assembly, which solves the problem that the disc brake in the existing market has poor stability during use, resulting in poor contact between the brake disc and the caliper, and the temperature of the brake disc rises rapidly after long-term use, and the brake disc is deformed and damaged due to the excessive temperature, thereby reducing the service life.

[0006] The utility model provides a disc brake assembly, comprising: a mounting plate and a brake disc, a fixing frame fixedly mounted on the bottom of the mounting plate, a fixing block fixedly mounted inside the fixing frame, hydraulic cylinders rotatably mounted on both ends of the fixing block, and the number of the hydraulic cylinders is two, connecting pieces are rotatably mounted on one end of the two hydraulic cylinders, connecting rods are rotatably mounted on both ends of the two connecting pieces, and the number of the connecting rods is four, rotating pieces are fixedly mounted on the bottoms of the two connecting pieces, one end of the two rotating pieces is rotatably mounted on the fixing frame, a clamping plate is fixedly mounted between one ends of every two connecting rods, and the number of the clamping plates is two, and the two clamping plates are rotatably mounted on the fixing frame.

[0007] Preferably, the brake disc is located between the two clamping plates, and heat dissipation holes are equidistantly provided in an annular shape on both sides of the outside of the brake disc, and the number of the heat dissipation holes is multiple.

[0008] Preferably, the brake disc is provided with equidistant annular air grooves inside, and the number of the air grooves is multiple.

[0009] Preferably, the brake disc comprises a base layer, and a high temperature resistant layer is attached to an outer side of the base layer.

[0010] Preferably, a wear-resistant layer is attached to the outer side of the high temperature resistant layer.

[0011] Preferably, the wear-resistant layer is made of ceramic coating.

[0012] Compared with the related art, the disc brake assembly provided by the utility model has the following beneficial effects:

[0013] The brake is installed on the car through the cooperation of the mounting plate and the bolts. When braking is required, the two hydraulic cylinders are extended. Since the hydraulic cylinders and the fixed block are rotated, the hydraulic cylinders and the connecting rod are rotated, and the clamping plates and the fixed frame are rotated, the two clamping plates are close to each other. The two clamping plates are used to install calipers. The calipers contact the brake disc, and then the brake disc stops rotating, effectively completing the braking. The rotating part greatly improves the stability of the clamping plate rotation, thereby improving the braking effect. The structure is simple and easy to use.

[0014] Long-term braking of the brake disc will generate high temperature, which can easily cause the brake disc to deform, thus affecting the braking effect. When the brake disc rotates, air enters the interior of the brake disc through the air slot and is discharged through the heat dissipation holes, thus having a good heat dissipation function and greatly improving practicality.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a disc brake assembly provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the splint installation structure shown; Figure 3 for Figure 1 The cross-sectional structure diagram of the brake disc shown; Figure 4 for Figure 1 The schematic diagram of the brake disc structure shown in the figure is a disc brake assembly, comprising: a mounting plate 1 and a brake disc 9, a fixing frame 2 is fixedly mounted on the bottom of the mounting plate 1, a fixing block 3 is fixedly mounted inside the fixing frame 2, hydraulic cylinders 4 are rotatably mounted on both ends of the fixing block 3, and the number of hydraulic cylinders 4 is two, a connecting member 5 is rotatably mounted on one end of the two hydraulic cylinders 4, a connecting rod 7 is rotatably mounted on both ends of the two connecting members 5, and the number of connecting rods 7 is four, a rotating member 6 is fixedly mounted on the bottom of the two connecting members 5, one end of the two rotating members 6 is rotatably mounted on the fixing frame 2, and a fixed member 6 is fixedly mounted between one end of each two connecting rods 7 There are two clamping plates 8, both of which are rotatably mounted on the fixing frame 2. The brake is mounted on the car by the cooperation of the mounting plate 1 and the bolts. When braking is required, the two hydraulic cylinders 4 are extended. Since the hydraulic cylinders 4 are rotatably mounted on the fixing block 3, the hydraulic cylinders 4 and the connecting rod 7 are rotated, and the clamping plates 8 are rotatably mounted on the fixing frame 2, so that the two clamping plates 8 are close to each other. The two clamping plates 8 are used to install calipers, and the calipers are in contact with the brake disc 9, so that the brake disc 9 stops rotating, effectively completing braking, and the rotating member 6 greatly improves the stability of the rotation of the clamping plates 8, thereby improving the braking effect. The structure is simple and easy to use.

[0022] The brake disc 9 is located between the two clamping plates 8. Both sides of the outside of the brake disc 9 are equidistantly provided with heat dissipation holes 10, and the number of the heat dissipation holes 10 is multiple. The inside of the brake disc 9 is equidistantly provided with air grooves 11, and the number of the air grooves 11 is multiple. Long-term braking of the brake disc 9 will generate high temperature, and the high temperature will easily cause the brake disc 9 to deform, thereby affecting the braking effect. When the brake disc 9 rotates, air enters the inside of the brake disc 9 through the air grooves 11, and is discharged through the heat dissipation holes 10, thereby having a good heat dissipation function, which greatly improves practicality.

[0023] The brake disc 9 includes a base layer 901, a high temperature resistant layer 902 is adhered to the outer side of the base layer 901, a wear-resistant layer 903 is adhered to the outer side of the high temperature resistant layer 902, the wear-resistant layer 903 is made of ceramic paint, and the high temperature resistant layer 902 is made of silicone high temperature resistant paint. The high temperature resistant layer 902 enables the sleeve to have good high temperature resistance and avoids deformation of the brake disc 9 due to high temperature after long-term use. The wear-resistant layer 903 improves the wear resistance of the brake disc 9 and further extends the service life of the brake disc 9.

[0024] The working principle of a disc brake assembly provided by the utility model is as follows:

[0025] The first step: install the brake on the car through the cooperation of the mounting plate 1 and the bolts. When braking is needed, the two hydraulic cylinders 4 are extended. Since the hydraulic cylinder 4 and the fixed block 3 are rotatably installed, the hydraulic cylinder 4 and the connecting rod 7 are rotated, and the clamping plate 8 and the fixing frame 2 are rotatably installed, so that the two clamping plates 8 are close to each other. The two clamping plates 8 are used to install calipers. The calipers contact the brake disc 9, and then the brake disc 9 stops rotating, effectively completing the braking. The rotating member 6 greatly improves the stability of the rotation of the clamping plate 8, thereby improving the braking effect. The structure is simple and easy to use.

[0026] Step 2: Long-term braking of the brake disc 9 will generate high temperature, which can easily cause the brake disc 9 to deform, thereby affecting the braking effect. When the brake disc 9 rotates, air enters the interior of the brake disc 9 through the wind slot 11, and is then discharged through the heat dissipation holes 10, thereby having a good heat dissipation function, which greatly improves practicality. The material of the wear-resistant layer 903 is ceramic coating, and the material of the high-temperature resistant layer 902 is silicone high-temperature resistant coating. The high-temperature resistant layer 902 enables the shaft sleeve to have good high-temperature resistance, thereby avoiding deformation of the brake disc 9 due to high temperature due to long-term use. The wear-resistant layer 903 improves the wear resistance of the brake disc 9, further extending the service life of the brake disc 9.

[0027] Compared with the related art, the disc brake assembly provided by the utility model has the following beneficial effects:

[0028] The brake is installed on the car through the cooperation of the mounting plate 1 and the bolts. When braking is required, the two hydraulic cylinders 4 are extended. Since the hydraulic cylinder 4 and the fixing block 3 are rotatably installed, the hydraulic cylinder 4 and the connecting rod 7 are rotated, and the clamping plate 8 and the fixing frame 2 are rotatably installed, so that the two clamping plates 8 are close to each other. The two clamping plates 8 are used to install calipers. The calipers contact the brake disc 9, so that the brake disc 9 stops rotating, and the braking is effectively completed. The rotating member 6 greatly improves the stability of the rotation of the clamping plate 8, thereby improving the braking effect. The structure is simple and convenient to use.

[0029] Long-term braking of the brake disc 9 will generate high temperature, which can easily cause the brake disc 9 to deform, thereby affecting the braking effect. When the brake disc 9 rotates, air enters the interior of the brake disc 9 through the air groove 11 and is then discharged through the heat dissipation holes 10, thereby having a good heat dissipation function and greatly improving practicality.
