Description

Technical Field

[0001] The present invention relates to the technical field of disc brake disc, and more specifically, to a disc brake disc brake subassembly. Background Art

[0002] Disc brakes are a common automotive braking system, also known as "disc brakes" or "disc brakes". It slows down or stops the vehicle by applying braking force directly to the rotating metal disc of the wheel. The disc brake system consists of a brake disc, a brake caliper and a brake pad. In the disc brake system, when the driver steps on the brake pedal, the brake fluid is pushed into the brake caliper, causing the brake pad in the caliper to clamp or press against the rotating disc to brake the vehicle. Compared with the traditional drum brake system, it has better braking performance, faster response time and better heat dissipation performance. Disc brake systems are often used in high-performance vehicles and modern cars because they can provide stronger and more reliable braking force, while having better durability and stability.

[0003] The Chinese patent publication number CN117432731B discloses a disc brake assembly structure, which uses a specially shaped sleeve opening to correspond to a sleeve seat for installation and positioning, so that the brake disc can be stable and unable to rotate; this fixing method can provide stronger stability and prevent the brake disc from shaking or misaligning during use. Compared with the traditional bolt fixing method, it does not need to install multiple bolts or related accessories, reducing the complexity and tediousness of the installation process; the fixed disc structure can realize the installation and positioning of axles of different diameters, improving the flexibility and convenience of installation, and the brake disc can be removed more conveniently during later maintenance and replacement, reducing the maintenance workload and time cost.

[0004] Disc brakes mainly use brake pads to clamp brake discs, converting the car's kinetic energy into heat energy through friction. Therefore, when driving aggressively or braking continuously on a long downhill slope, you need to brake for a long time and multiple times. It takes time for the brake disc to dissipate heat, so it is easy to overheat the brake disc. High temperature will cause the brake disc to deform, thereby affecting the braking effect. Once the brake disc is deformed, it will cause vibration and imbalance during braking, affecting the vehicle's driving stability.

[0005] The brake pads of disc brakes are mainly driven by the brake fluid hydraulic pressure to clamp the brake disc. Therefore, when the brake disc overheats, the brake pads will also be affected and become hot, and the heat will be transferred to the brake fluid through the caliper. The brake fluid is sealed in a pipe, so it is not easy to dissipate heat and cool down. The brake fluid is prone to degradation at high temperatures, losing its lubricating properties and viscosity, causing the braking system to work unstable and the brake pedal to feel soft or ineffective.

[0006] Therefore, it is necessary to provide a disc brake subassembly to solve the above problems. Summary of the invention

[0040] Optionally, in some embodiments, see Fig.10 and Fig.11 The cooling component 3 also includes a second mounting frame 31, a plurality of water spray blocks 32 are fixedly mounted on the outer end of the second mounting frame 31, a water pipe 35 is mounted on the outer end of the second mounting frame 31, a plurality of baffles 34 are fixedly connected to the outer end of the second mounting frame 31, and a fixing plate 36 is fixedly connected to the outer end of the second mounting frame 31, the second mounting frame 31 is mounted on the outer end of the caliper housing 11 through the fixing plate 36, atomizing heads 33 are fixedly mounted on the outer ends of the plurality of water spray blocks 32, a water inlet 37 is provided on the outer end of the second mounting frame 31, a connecting water pipe 38 is connected to the outer end of the water inlet 37, and the connecting water pipe 38 is connected to the water pipe 35 through the water inlet 37.

[0041] The cooling component 3 in this scheme is mainly used to spray water to cool the disc brake disc component 2. The cooling component 3 and the disc brake disc component 2 are both circular and coaxially arranged. They are hollow in the middle, so that the transmission shaft of the car can pass through the cooling component 3 and the disc brake disc component 2 and connect with the wheel hub. A fixing plate 36 is fixed at the outer end of the mounting frame 31. The fixing plate 36 can be fixed to the caliper housing 11 by welding or bolts. A plurality of water spray blocks 32 are fixed at the outer end of the mounting frame 31. The plurality of water spray blocks 32 are all located at the edge of the mounting frame 31. A water pipe 35 is wound and fixed on the mounting frame 31 at the same time. The water pipe 35 and the plurality of water spray blocks 32 are all interconnected, so that it can supply water to multiple water spray blocks 32. A water inlet 37 is opened on the back of the mounting frame 2 31. A connecting water pipe 38 is fixedly installed on the outer end of the water inlet 37. The connecting water pipe 38 is connected to the water pipe 35 through the water inlet 37, and the other end of the connecting water pipe 38 is connected to the water outlet on the valve housing 66. A plurality of baffles 34 are also fixed on the mounting frame 2 31. The baffles 34 are located in front of the water spray block 32 and are staggered with the water spray block 32. They mainly play the role of protecting the water spray block 32 and the water pipe 35, preventing the sand and gravel rolled up by the tire from damaging the water spray block 32 and the water pipe 35, thereby improving the protection.

[0042] An atomizing head 33 is also installed on each water spray block 32 for discharging water. The atomizing head 33 mainly plays the role of atomizing the water sprayed by the water spray block 32. By atomizing the water and then spraying it on the disc brake disc assembly 2, the uniformity of the spraying can be improved, and the entire disc brake disc assembly 2 can be cooled at the same time to prevent local rapid cooling. The deformation of the disc brake disc assembly 2 due to the large temperature difference is improved, and the uniformity of cooling is improved. At the same time, the atomized water can also cover a farther area, so that while cooling the disc brake disc assembly 2, it can also cool the heat dissipation assembly 5, the caliper assembly 1 and the wheel hub, thereby achieving the purpose of cooling the entire brake system.

[0043] Optionally, in some embodiments, see Fig.10 and Fig.13 The heat dissipation assembly 5 includes a plurality of heat sinks 51 and a plurality of connecting blocks 54. The diameters of the plurality of heat sinks 51 decrease successively. The plurality of heat sinks 51 are interconnected through the plurality of connecting blocks 54. Ventilation holes 52 are provided at the outer ends of the plurality of heat sinks 51. A plurality of mounting rings 53 are fixedly connected to the outer end of one of the heat sinks 51. The mounting ring 53 is sleeved on the outer end of the oil pipe 43.

[0044] The heat dissipation component 5 in this solution is arranged on the connecting component 4, and is mainly used to assist the heat dissipation of the brake oil. When the brake disc is overheated, the brake pad will also be affected and become hot. Since the entire brake system is mostly made of metal, the heat conduction efficiency is relatively high, and the brake oil is prone to overheating, resulting in unstable operation of the brake system. The heat dissipation component 5 is mainly composed of three heat sinks 51. The diameters of the three heat sinks 51 decrease in sequence, so that they can be connected together in sequence through the connecting block 2 54, so as to better dissipate heat. On the heat sink 51 with the smallest diameter, that is, on the heat sink 51 with the smallest diameter, a plurality of mounting rings 53 are fixed. By sleeved on the oil pipe 2 43 with a plurality of mounting rings 53, the heat sink 51 can be The heat sink 51 with the smallest diameter is fitted and wrapped around the outer end of the oil pipe 43. The connecting component 4 is made of metal. When the overheated brake oil flows through the inside of the oil pipe 43, the heat of the brake oil will be first transferred to the heat sink 51 with the smallest diameter through the oil pipe 43, and then the heat will be dissipated into the air through multiple connecting blocks 54 and the heat sink 51 in sequence. At the same time, multiple ventilation holes 52 are also provided on the heat sink 51. Air can enter the gaps between the multiple heat sinks 51 through the ventilation holes 52, so that it can dissipate heat better. It is worth mentioning that the heat dissipation component 5 will also be located in front of the cooling component 3. When the cooling component 3 sprays water, it will also be sprayed onto the heat dissipation component 5, which can accelerate its heat dissipation more quickly.

[0045] Optionally, in some embodiments, see Figure 14-16 The control component 6 also includes a piston housing 61, which is fixedly mounted on the outer end of the mounting frame 31. The interior of the piston housing 61 is hollow, and the top of the piston housing 61 is connected to the oil outlet 46 through an oil pipeline. The bottom of the piston housing 61 is fixedly connected to a valve housing 66, which is hollow inside and has two ends, namely a water inlet and a water outlet. The water outlet is connected to the connecting water pipe 38, and the water inlet is connected to an external water supply system.

[0046] The control assembly 6 also includes a driving piston 62, which is slidably connected to the inner wall of the piston housing 61. A plurality of sealing rings 63 are installed at the outer end of the driving piston 62, and the sealing rings 63 abut against the inner wall of the piston housing 61. The top of the movable sleeve 64 is fixedly connected to the bottom end of the driving piston 62. The bottom end of the movable block 69 is fixedly connected to a connecting rod 65, which passes through the movable sleeve 64 and extends to the outside, and the bottom end of the connecting rod 65 passes through the valve housing 66 and extends to the inside. A valve ball 67 is installed inside the valve housing 66, and the bottom end of the connecting rod 65 is fixedly connected to the valve ball 67. The valve ball 67 is driven to rotate by the connecting rod 65 to control the opening and closing of the internal channel of the valve housing 66.

[0047] The control component 6 in this scheme is mainly used to control the cooling component 3 to spray water. The piston housing 61 is connected to the oil outlet 46 through a pipeline. The piston housing 61 is fixed to the outer end of the mounting frame 31. The interior of the piston housing 61 is hollow. The driving piston 62 slides inside it. A plurality of sealing rings 63 are sleeved on the outer end of the driving piston 62, thereby increasing the sealing between the driving piston 62 and the inner wall of the piston housing 61. A movable sleeve 64 is fixedly installed at the bottom end of the driving piston 62. The interior of the movable sleeve 64 is hollow. Two arc grooves 68 are provided inside the movable sleeve 64. The movable block 69 is located inside the movable sleeve 64. Slide blocks 610 are fixed on both sides of the movable block 69. The slide blocks 610 are connected to the arc grooves 68 in a sliding manner. Then, the arc groove 68 covers a quarter of the area inside the movable sleeve 64, that is, in a top view, the angle between the head end and the tail end of the arc groove 68 is 90°, so that when the slider 610 slides from the head end of the arc groove 68 to the tail end along the path of the arc groove 68, the movable block 69 will rotate 90°, and a connecting rod 65 is fixed to the bottom end of the movable block 69. The connecting rod 65 passes through the bottom end of the movable sleeve 64 and the valve housing 66 in sequence, and extends to the inside of the valve housing 66, and is fixedly connected to the valve ball 67 inside the valve housing 66. The two ends of the valve housing 66 are respectively a water inlet end and a water outlet end. The water outlet end is connected to the connecting water pipe 38, and the water inlet end needs to be connected to an external water supply system through a water pipe. The water supply system is mainly composed of a water storage tank, which is mainly used to store water.

[0048] Whether the water entering the valve housing 66 can flow into the cooling component 3 is mainly controlled by the valve ball 67. When the user steps on the pedal device 10, the vacuum booster pump 9 will pressurize the brake oil in the brake oil pot 8 and push it into the connecting component 4. At this time, through the diversion effect of the connecting component 4, it can not only provide braking force for the caliper assembly 1, but also input into the piston housing 61 through the oil outlet 46, and then push the driving piston 62 to move downward. At this time, the movable sleeve 64 will be driven to move downward. Since the valve housing 66 is fixed to the bottom end of the piston housing 61, the movable block 69 will not move up and down, and can only be driven by the arc groove 68 inside the movable sleeve 64 to rotate. According to the curvature of the arc groove 68 , the movable block 69 will drive the connecting rod 65 to rotate 90°, so that the valve ball 67 rotates 90° to open the channel inside the valve housing 66, so that water can enter the cooling component 3 through the valve housing 66 to supply water to the cooling component 3. When the pedal device 10 stops, the brake pad 16 on the inner side of the caliper housing 11 will be driven to reset by the abutment piston 15 through the back-drawing force of the vacuum booster pump 9. At the same time, the driving piston 62 will also move upward to reset. At this time, the movable sleeve 64 will also reset, forcing the valve ball 67 to rotate 90° in the opposite direction to reset. Through the control of the control component 6, the cooling component 3 can work synchronously with the caliper component 1, and can stop working when not braking to save water and improve linkage.

[0049] Working principle: When the device is used for braking, the user needs to step on the pedal device 10, and the vacuum booster pump 9 will pressurize the brake oil in the brake oil tank 8 and push it into the connecting component 4. At this time, the pressure of the brake oil is transmitted to the caliper component 1 and the control component 6 respectively through the diversion effect of the connecting component 4. Through Pascal's law, the pressure inside the six piston chambers 13 can be made consistent, so that the abutting piston 15 can move back and forth inside the piston chamber 13, which is used to push the brake pads 16, so that the two brake pads 16 move in opposite directions, and the disc brake assembly 2 can be clamped, thereby providing braking force for the wheel hub; At this time, the brake oil is input into the piston housing 61 through the oil outlet 46, and then the driving piston 62 is pushed to move downward, the movable sleeve 64 will be driven to move downward, and the connecting rod 65 will be driven by the arc groove 68 inside the movable sleeve 64 to rotate, and the movable block 69 will drive the connecting rod 65 to rotate 90°, so that the valve ball 67 rotates 90° to open the channel inside the valve housing 66, so that water can enter the cooling component 3 through the valve housing 66 to supply water to the cooling component 3. Each water spray block 32 is also equipped with an atomizing head 33 for water discharge, and the water sprayed by the water spray block 32 is atomized to cool the entire disc brake assembly 2 at the same time, and the entire brake system can be cooled; The heat dissipation component 5 is arranged on the connecting component 4, and is mainly used to assist in the heat dissipation of the brake oil. The heat dissipation component 5 is mainly composed of three heat sinks 51, which are mounted on the oil pipe 43 through multiple mounting rings 53. When the overheated brake oil flows through the inside of the oil pipe 43, the heat is dissipated into the air through multiple connecting blocks 54 and the heat sink 51 in sequence. The heat dissipation component 5 is located in front of the cooling component 3. When the cooling component 3 sprays water, its heat dissipation will be accelerated more quickly.
