Description

Technical Field

[0001] The invention relates to the field of fixed disc brakes, and in particular to a fixed disc brake capable of preventing a brake disc from excessively shaking. Background Art

[0002] Fixed disc brake is a kind of automobile braking device, which is mainly composed of brake disc, brake caliper, brake pad and brake fluid pipeline. The brake disc is a metal disc fixed on the wheel hub, and the brake caliper is fixed on the vehicle's suspension system or axle. When the driver steps on the brake pedal, the piston in the brake caliper pushes the brake pad to clamp the brake disc. The friction between the brake pad and the brake disc is used to reduce the rotation speed of the wheel, thereby braking the vehicle.

[0003] Traditional fixed disc brakes mainly rely on the heat conduction of the brake disc itself and the natural convection of the surrounding air to dissipate heat. During long-term or high-intensity braking, such as when the vehicle is driving downhill for a long time or frequently braking, the heat generated by the brake disc cannot be dissipated in time, and the temperature of the brake disc will rise sharply, which is prone to thermal decay. The decay will cause the friction coefficient between the brake pad and the brake disc to decrease, which greatly increases the braking distance of the vehicle. In an emergency, it is impossible to stop the vehicle in time, which seriously threatens driving safety. Secondly, the high temperature generated by long-term braking has serious damage to the material properties of the brake disc and brake pad, resulting in uneven contact between the brake pad and the brake disc. In severe cases, the friction between the brake pad and the brake disc will generate a large number of high-temperature sparks, and the sparks will cause the surrounding components to burn, such as rubber pipes and sound insulation materials near the brake system. At the same time, traditional brakes have no mechanism to actively monitor and respond to the high temperature of the brake disc. It cannot take measures before the temperature of the brake disc rises to the critical value that affects the braking performance, and can only passively withstand a series of problems caused by high temperature.

[0004] In addition, traditional brakes do not have the ability to automatically recover after the brake performance of the brake disc decreases due to high temperature. It can only rely on natural cooling and wait for the heat of the brake disc to slowly dissipate into the surrounding environment. This process takes a long time, and there is no corresponding circulation mechanism to ensure that the same problem will not occur again during the next braking. In addition, because the vehicle is in an unsafe temporary parking state while waiting for cooling, other risks are increased, such as slipping, being rear-ended by the vehicle behind, etc.

[0005] Secondly, traditional braking systems are prone to uneven contact between brake pads and brake discs. This is due to the piston design or brake structure. For example, some traditional brakes only have one piston, which cannot ensure that all parts contact the brake disc evenly and at the same time during braking. This uneven contact will cause the brake disc to be subjected to uneven force during braking, excessive local pressure, and poor braking effect. Traditional brake pads are usually planar structures. During braking, the heat generated can only be conducted to the brake disc through a limited contact surface, and then dissipated by relying on the brake disc's own heat dissipation capacity and the natural convection of the surrounding air. Due to the characteristics of its planar structure, the bite effect with the brake disc is relatively weak. In emergency braking situations, it takes a certain amount of time to achieve the ideal braking force, which increases the braking distance.

[0006] Traditional fixed disc brakes often have only a single braking method, that is, braking is achieved by clamping the brake disc with a brake caliper. In some emergency or special situations, a single braking method cannot meet higher requirements for braking effects. For example, in emergency braking at high speeds or when a vehicle is heavily loaded and requires stronger braking force, the braking capacity of traditional brakes is limited. When traditional fixed disc brakes encounter a situation where the braking force of the brake caliper is insufficient, there is no corresponding supplementary braking measure, which can easily lead to excessive braking distance and increase the possibility of accidents.

[0007] Therefore, it is necessary to provide a fixed disc brake which can prevent the brake disc from excessively vibrating, so as to solve the above problems. Summary of the invention

[0008] In view of the shortcomings of the prior art, an object of the present invention is to provide a fixed disc brake that can prevent excessive vibration of the brake disc.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fixed disc brake capable of preventing a brake disc from vibrating excessively, comprising a brake caliper assembly and a brake disc, wherein the brake disc is arranged inside the brake caliper assembly, a cooling component for cooling the high-temperature brake disc is arranged inside the brake caliper assembly, an anti-vibration component for preventing the brake disc from vibrating excessively when braking the brake disc is arranged inside the brake caliper assembly, and an emergency brake component for performing emergency braking on the brake disc is arranged inside the brake disc.

[0010] Preferably, the cooling component includes a truncated cone-shaped groove, which is opened inside the brake caliper assembly, and the inside of the truncated cone-shaped groove is symmetrically fixedly connected with positioning clips, and one end of the two positioning clips away from the truncated cone-shaped groove is clamped with a fixing frame.

[0011] Preferably, the cooling component also includes a memory metal block, the memory metal block is fixedly connected to one end of the fixing frame, the other end of the memory metal block is clamped with a cooling tank, and a sealing tube is provided between the memory metal block and the cooling tank.

[0012] Preferably, the anti-shake assembly includes a hydraulic tank group, the hydraulic tank group is fixedly connected to both sides of the brake caliper group, three piston rods are slidably connected inside the hydraulic tank group, an induction coil is provided at one end of the hydraulic tank group close to the brake caliper group, and a brake pad is fixedly connected to one end of the piston rod away from the hydraulic tank group.

[0013] Preferably, the emergency brake assembly includes a connecting plate, which is fixedly connected to the inner side of the brake disc through a metal rod, and the interior of the connecting plate is fixedly connected to a limiting pin, and the outer wall of the limiting pin is slidably connected to a first elastic brake pad.

[0014] Preferably, the emergency brake assembly also includes a metal sheet, which is fixedly connected to the inside of the first elastic brake sheet, and the outer wall of the limiting pin is slidably connected to the second elastic brake sheet, and an electromagnet block is arranged on the side of the second elastic brake sheet close to the first elastic brake sheet.

[0015] Preferably, the truncated cone-shaped groove is opened on the outer side of the brake disc, a coolant is arranged inside the cooling tank, and the interior of the cooling tank is in a negative pressure state.

[0016] Preferably, the side of the brake pad away from the piston rod is configured to be wavy.

[0017] Preferably, the sizes of the three piston rods are arranged in sequence as small, medium and large, and the electromagnet block and the metal sheet are both sleeved on the outside of the limiting pin.

[0018] Preferably, the piston rod is electrically connected to a power source used by the device, and the electromagnet block is electrically connected to the induction coil.

[0019] The present invention provides a fixed disc brake capable of preventing a brake disc from excessively vibrating. Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a cooling component, when the brake pad brakes the brake disc for a long time, the brake disc will gradually heat up. In severe cases, the brake disc will generate high-temperature sparks. At this time, the heated brake disc and the flying sparks will cause the memory metal block to deform, and then the memory metal block will stop contacting the sealing tube. The cooling tank that loses the contact with the sealing tube will cause the coolant to be quickly sprayed onto the surface of the brake disc due to the internal negative pressure, so that the brake disc will cool down quickly. Compared with the traditional fixed disc brake, overheating caused by long-term braking will cause brake failure. The above-mentioned brake with an active cooling system can effectively prevent brake failure by timely cooling, ensuring that the vehicle can brake safely under any circumstances, and can provide the driver with reliable braking performance even in extreme braking situations, such as emergency braking or long-term continuous braking.

[0020] Secondly, the memory metal block can change shape according to temperature and external stimuli. As a temperature-sensitive trigger element, it responds accurately to the high temperature and sparks of the brake disc. Compared with traditional fixed disc brakes that rely solely on natural heat dissipation or simple ventilation heat dissipation, this actively triggered cooling method can respond to overheating of the brake disc more promptly. After overheating due to long-term braking, the braking force of traditional brakes will decrease due to thermal decay. This design can effectively avoid this situation and maintain the stability of braking performance. The design of the cooling tank and the sealing tube enables the coolant to be quickly sprayed onto the brake disc surface when needed. The negative pressure design inside the cooling tank can ensure that the coolant is sprayed out quickly and evenly, thereby quickly reducing the temperature of the brake disc and restoring its braking performance.

[0021] Secondly, the spraying of coolant can not only reduce the temperature of the brake disc, but also reduce the fire caused by sparks. At the same time, the coolant will vaporize when it contacts the high-temperature brake disc, forming a vapor protective film to prevent oxygen from contacting the high-temperature metal surface, thereby reducing the generation of sparks and reducing the risk of fire.

[0022] Finally, after the cooling tank and the sealing tube can be replaced because the negative pressure inside the cooling tank causes the coolant to be quickly sprayed onto the surface of the brake disc, causing the brake disc to cool down quickly. The memory metal block will return to its original shape after the brake disc cools down, making it easier to cool the brake disc again later, thus achieving the purpose of recycling. The entire cooling system has a recyclable function, which solves the problem that once the braking performance of traditional brakes is reduced due to high temperature, there is no automatic recovery mechanism, and it takes a long time to wait for natural cooling or stop the vehicle for cooling, which affects the continuous use and safety of the vehicle, in sharp contrast to traditional fixed disc brakes.

[0023] 2. Through the setting of the anti-shake component, when the brake caliper group is working, due to the different sizes of the three pistons, the thrust generated under the same hydraulic pressure is also different. The thrust generated by the small piston is relatively small, while the thrust generated by the large piston is relatively large. Compared with the traditional braking system, this design enables the braking torque to change linearly from small to large during the contact process between the brake pad and the brake disc. Because they jointly push a brake pad, the contact between the brake pad and the brake disc can be smoother and the pressure can be increased gradually, thereby achieving a more linear braking process.

[0024] Secondly, the traditional braking system will cause uneven contact between the brake pad and the brake disc. For example, only one large piston will make contact first and apply a large force, which will cause excessive force on the local brake pad, thereby causing the brake disc to shake during braking. However, by pushing one brake pad at the same time with three pistons and making the braking torque change linearly due to their size difference, the brake pad can fit the brake disc more evenly and maintain stable contact during the entire braking process, effectively avoiding brake disc shaking.

[0025] Secondly, the shape of the brake pad is set to a special wavy shape. Compared with the traditional flat brake pad, the brake pad is no longer a simple plane, but has more ups and downs. This wavy structure greatly increases the contact area between the brake pad and the brake disc. From a geometric point of view, the area of ​​the wavy surface is larger than the plane of the same size. During the braking process, heat can be conducted over a larger area. For example, when the vehicle brakes, the heat generated by the braking will be dissipated to the surrounding air through the contact surface of the brake pad and the brake disc, and the wavy structure can provide better bite effect in the initial stage of braking. When the brake pad starts to contact the brake disc, the wavy raised parts first contact the brake disc. These raised parts can quickly cut into the tiny unevenness on the surface of the brake disc, generating greater friction.

[0026] At the same time, the wavy brake pads can also promote air convection during braking. Air can flow between the wavy grooves and protrusions to take away heat, just like the fins of a radiator. This structure can enhance air fluidity. During braking, the air flow of traditional flat brake pads is relatively smooth, and they mainly rely on natural convection to dissipate heat. The wavy brake pads can guide the air to form complex convection paths on their surface, thereby improving heat dissipation efficiency.

[0027] 3. Through the setting of the emergency brake assembly, when the brake caliper group exerts the maximum braking effect, the hydraulic tank group will squeeze the piston rod to contact the induction coil, and then the induction coil will make the electromagnet block electromagnetically absorb the metal sheet, and finally make the first elastic brake pad contact the second elastic brake pad, and then make the outer sides of the first elastic brake pad and the second elastic brake pad contact the connecting plate at the same time, and then the rotation speed of the brake disc is reduced through the connecting plate, so as to achieve additional braking effect. Compared with traditional brakes, when the brake caliper group reaches the maximum braking effect, there is still a subsequent braking mechanism, and this multi-stage braking structure can better cope with extreme braking conditions. When the braking effect of the brake caliper group is insufficient, the additional braking mechanism can intervene in time to more effectively reduce the rotation speed of the brake disc.

[0045] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0046] Implementation example Figures 1 to 11 As shown, a fixed disc brake capable of preventing excessive vibration of a brake disc is provided in one embodiment of the present invention, comprising a brake caliper assembly 11 and a brake disc 12. The brake disc 12 is arranged inside the brake caliper assembly 11. A cooling component for cooling the high-temperature brake disc 12 is arranged inside the brake caliper assembly 11. An anti-vibration component for preventing excessive vibration of the brake disc 12 when the brake disc 12 is braked is arranged inside the brake caliper assembly 11. An emergency braking component for emergency braking is arranged inside the brake disc 12.

[0047] The cooling component includes a truncated cone-shaped groove 21 which is opened inside the brake caliper assembly 11 . Positioning clips 22 are symmetrically fixedly connected inside the truncated cone-shaped groove 21 . A fixing frame 23 is clamped on one end of the two positioning clips 22 away from the truncated cone-shaped groove 21 .

[0048] The cooling component also includes a memory metal block 24 , which is fixedly connected to one end of the fixing frame 23 , and a cooling tank 25 is clamped on the other end of the memory metal block 24 , and a sealing tube 26 is provided between the memory metal block 24 and the cooling tank 25 .

[0049] The anti-shake assembly includes a hydraulic tank group 31, which is fixedly connected to both sides of the brake caliper group 11. Three piston rods 33 are slidably connected inside the hydraulic tank group 31. An induction coil 34 is provided at one end of the hydraulic tank group 31 close to the brake caliper group 11, and a brake pad 32 is fixedly connected to one end of the piston rod 33 away from the hydraulic tank group 31.

[0050] The emergency brake assembly includes a connecting plate 41, which is fixedly connected to the inner side of the brake disc 12 through a metal rod. The interior of the connecting plate 41 is fixedly connected to a limit pin 42, and the outer wall of the limit pin 42 is slidably connected to a first elastic brake pad 43.

[0051] The emergency brake assembly also includes a metal sheet 46, which is fixedly connected to the inside of the first elastic brake sheet 43. The outer wall of the limiting nail 42 is slidably connected to the second elastic brake sheet 44, and an electromagnet block 45 is provided on one side of the second elastic brake sheet 44 close to the first elastic brake sheet 43.

[0052] The truncated cone-shaped groove 21 is opened on the outer side of the brake disc 12 . The cooling tank 25 is provided with coolant inside, and the inside of the cooling tank 25 is in a negative pressure state, so that the cooling tank 25 is triggered to spray and cool the brake disc 12 .

[0053] The side of the brake pad 32 away from the piston rod 33 is configured to be wavy, so as to improve the braking effect and heat dissipation effect of the brake pad 32 .

[0054] The electromagnet block 45 and the metal sheet 46 are both sleeved on the outer side of the limiting nail 42 , so that the limiting nail 42 can avoid affecting the magnetic attraction effect of the electromagnet block 45 and the metal sheet 46 .

[0055] The sizes of the three piston rods 33 are arranged in small, medium and large order, so that the braking torque generated by the brake pad 32 changes linearly from small to large. There is an electrical connection between the piston rod 33 and the power supply used by the equipment, and there is an electrical connection between the electromagnet block 45 and the induction coil 34, so that when the piston rod 33 conflicts with the induction coil 34, the electromagnet block 45 electromagnetically attracts the metal sheet 46.

[0056] Working principle: In the initial state, the two ends of the sealing tube 26 are in conflict with the memory metal block 24 and the cooling tank 25 respectively, the brake pad 32 does not conflict with the brake disc 12, the piston rod 33 does not conflict with the induction coil 34, the first elastic brake pad 43 is in conflict with the top of the limiting nail 42, and the electromagnet block 45 does not magnetically attract the metal sheet 46.

[0057] During operation, when the brake caliper group 11 is used to brake the brake disc 12, the brake caliper group 11 will inject hydraulic oil into the interior of the hydraulic tank group 31, and then the hydraulic oil will resist the piston rod 33 and slide along the interior of the hydraulic tank group 31. Since the sizes of the three piston rods 33 are arranged in small, medium and large order, the three piston rods 33 of different sizes will then push the brake pad 32 to resist the brake disc 12 to brake the brake disc 12.

[0058] During this process, due to the different sizes of the three piston rods 33, the thrust generated under the same hydraulic pressure is also different. The thrust generated by the small piston is relatively small, while the thrust generated by the large piston is relatively large. As a result, the braking torque can change linearly from small to large. Because the three piston rods 33 jointly push a brake pad 32, the contact between the brake pad 32 and the brake disc 12 can be smoother and the pressure can be increased gradually, thereby achieving a more linear braking process, allowing the brake pad 32 to fit the brake disc 12 more evenly and maintain stable contact throughout the braking process, effectively avoiding excessive shaking of the brake disc 12.

[0059] Secondly, because the side of the brake pad 32 away from the piston rod 33 is set to be wavy, when the wavy surface of the brake pad 32 contacts the brake disc 12, this wavy structure greatly increases the contact area between the brake pad 32 and the brake disc 12, so that heat can be conducted over a larger area, so that the heat generated by braking will be dissipated to the surrounding air through the contact surface of the brake pad 32 and the brake disc 12. At the same time, the wavy brake pad 32 can also promote air convection during braking, just like the fins of a radiator. This structure can enhance the fluidity of the air, allowing the air to flow between the wavy grooves and protrusions of the brake pad 32 to take away heat.

[0060] In addition, the wavy structure can provide a better bite effect in the initial stage of braking. When the brake pad 32 starts to contact the brake disc 12, the wavy raised parts of the brake pad 32 first contact the brake disc 12. These raised parts can quickly cut into the tiny unevenness on the surface of the brake disc 12 to generate greater friction.

[0061] When emergency braking at high speeds or when a vehicle is heavily loaded and a stronger braking force is required, the braking capacity of traditional brakes is limited. When traditional fixed disc brakes encounter a situation where the brake caliper has insufficient braking force, it is easy to cause a braking distance that is too long, which can easily lead to accidents. When the structure uses the brake caliper group 11 to use the maximum braking force to brake the brake disc 12, the brake caliper group 11 injects hydraulic oil into the interior of the hydraulic tank group 31, so that the hydraulic oil moves to the bottom of the hydraulic tank group 31 against the piston rod 33.

[0062] Because there is an electrical connection between the piston rod 33 and the power supply used by the equipment, and there is an electrical connection between the electromagnet block 45 and the induction coil 34, the piston rod 33 then conflicts with the induction coil 34, and the induction coil 34 will simultaneously energize the electromagnet block 45, and the energized electromagnet block 45 will quickly magnetically attract the metal sheet 46, so that the metal sheet 46 drives the first elastic brake pad 43 to slide quickly toward the second elastic brake pad 44.

[0063] When the electromagnet block 45 collides with the magnetically attracted metal sheet 46, the first elastic brake pad 43 collides with the second elastic brake pad 44 simultaneously. After the first elastic brake pad 43 collides with the second elastic brake pad 44, the diameters of the two will gradually increase. Finally, the outer walls of the first elastic brake pad 43 and the second elastic brake pad 44 collide with the inner wall of the connecting plate 41, so that the first elastic brake pad 43 and the second elastic brake pad 44 rub against the connecting plate 41 at the same time, and then reduce the rotation speed of the brake disc 12 through the connecting plate 41, so as to achieve the effect of braking the brake disc 12 again.

[0064] If the brake caliper assembly 11 brakes the brake disc 12 normally, the first elastic brake pad 43 , the second elastic brake pad 44 , the electromagnet block 45 and the metal sheet 46 will not affect the normal braking effect of the brake caliper assembly 11 .

[0065] At the same time, when the brake caliper group 11 is required to exert the maximum braking effect, additional braking effect can be achieved. Compared with traditional brakes, when the brake caliper group 11 reaches the maximum braking effect, there is still a subsequent braking mechanism. This multi-stage braking structure can better cope with extreme braking conditions. When the braking effect of the brake caliper group 11 is insufficient, the additional braking mechanism can intervene in time to more effectively reduce the rotation speed of the brake disc 12.

[0066] When the vehicle travels downhill for a long time or brakes suddenly frequently, the heat generated by the brake caliper assembly 11 braking the brake disc 12 cannot be dissipated in time, and the temperature of the brake disc 12 will rise sharply. In severe cases, the friction between the brake pad 32 and the brake disc 12 will generate a large number of high-temperature sparks. During this process, the high-temperature brake disc 12 and the flying high-temperature sparks will trigger the memory metal block 24 to deform.

[0067] Subsequently, the deformed memory metal block 24 cannot resist the sealing tube 26. At this time, one end of the sealing tube 26 loses the resistance of the memory metal block 24 and cannot continue to seal the cooling tank 25. Because the cooling tank 25 is provided with coolant, and the interior of the cooling tank 25 is in a negative pressure state, the coolant in the cooling tank 25 in the contact-sealed state will be sprayed along the fixing frame 23 to the surface of the high-temperature brake disc 12, so that the brake disc 12 is quickly cooled, so that the brake caliper assembly 11 can provide the driver with reliable braking performance in extreme braking conditions, such as emergency braking or long-term continuous braking.

[0068] Secondly, the memory metal block 24 can change its shape according to temperature and external stimuli. As a temperature-sensitive trigger element, it accurately responds to the high temperature and sparks of the brake disc 12. Compared with the traditional fixed disc brake that simply relies on natural heat dissipation or simple ventilation heat dissipation, this actively triggered cooling method can respond to the overheating of the brake disc 12 more promptly, thereby quickly taking away heat, reducing the temperature of the brake disc 12, and restoring its braking performance.

[0069] Secondly, the coolant in the cooling tank 25 can not only reduce the temperature of the brake disc 12, but also reduce the fire caused by spark splashing. At the same time, the coolant will vaporize when it contacts the high-temperature brake disc 12, forming a vapor protective film to prevent oxygen from contacting the high-temperature metal surface, thereby reducing the generation of sparks and reducing the risk of fire.

[0070] Finally, new coolant is injected into the cooling tank 25 again, and a new sealing tube 26 is added. The memory metal block 24 will restore its original shape as the brake disc 12 cools down, making it easier to cool down the high-temperature brake disc 12 again, while achieving the purpose of recycling. This makes the entire cooling system recyclable, in sharp contrast to traditional fixed disc brakes.
