Description

Technical Field

[0001] This utility model relates to the field of brake pad technology, specifically to a brake pad accessory with efficient heat dissipation. Background Technology

[0002] Brake pads are a key component of a car's braking system. Their main function is to slow down or stop the vehicle's movement by rubbing against the brake disc. During the friction process, the brake disc generates heat, which affects the braking effect.

[0003] To overcome the aforementioned defects, a prior art Chinese patent (publication number: CN215409887U) discloses a brake pad that facilitates heat dissipation, including a brake pad body and a friction block. The friction block is provided on one side of the brake pad body, and the brake pad body has multiple through holes. The inner side of the friction block has multiple first grooves. The friction block adopts a fan-shaped design, which is intended to match the braking center of the brake disc and to make the right-angled edges smoother, easily eliminating stress concentration, and ensuring a smooth transition between the edges, thus reducing noise. The brake pad fully engages with the working surface of the brake disc, preventing the edges of the brake disc from being worn into grooves, thereby avoiding insufficient braking force and abnormal noise. Through the design of the friction block shape, the through holes on the brake pad body, and the grooves on the friction block, air circulation is increased, heat dissipation performance is improved, and dust generated by friction can be quickly removed, greatly improving the brake pad's resistance to heat fading and making driving safer.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: by rubbing against the brake disc to slow down or stop the movement of the vehicle, the friction of the brake disc generates heat during the friction process. Existing vehicle braking components generally dissipate heat by generating airflow through the rotation of their internal structure, but the heat dissipation method of brake pads is relatively simple and has low heat dissipation efficiency, which easily leads to heat accumulation. Utility Model Content

[0005] The purpose of this invention is to provide a brake pad accessory with efficient heat dissipation, in order to solve the problem that the brake pad heat dissipation method is relatively simple and the heat dissipation efficiency is low, which easily leads to heat accumulation in the above-mentioned background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a brake pad accessory with efficient heat dissipation, comprising a brake disc and a caliper, wherein the caliper is mounted on the outside of the brake disc, and a flange is bolted to the center of the brake disc;

[0007] The caliper has two symmetrically distributed brake pads installed inside, and friction blocks are fixedly connected to the sides of the two brake pads that are close to each other. The friction blocks have equidistantly distributed ventilation grooves and exhaust grooves on their inner sides, and the depth of the ventilation grooves is greater than the depth of the exhaust grooves. The ventilation grooves are arranged in an arc shape with the brake disc as the center on the inner side of the friction blocks, and the exhaust grooves are arranged radially on the inner side of the friction blocks, and the exhaust grooves and ventilation grooves are perpendicular to each other.

[0008] Preferably, the brake pad has two symmetrically distributed guide rings fixedly connected to its outer side, and the caliper has two symmetrically distributed guide pins fixedly connected to its inner side, with the guide rings sleeved on the outer side of the guide pins and slidingly engaged with them.

[0009] Preferably, pistons are fixedly connected to both ends of the caliper, and the telescopic ends of the pistons extend into the caliper and are connected to the brake pads.

[0010] Preferably, a rubber rod is fixedly connected to the inner side of each of the two brake pads, and an electrode block is fixedly connected to the end of the rubber rod away from the brake pad.

[0011] Preferably, the rubber rods and electrode blocks on the two brake pads are aligned with each other, and a corrugated sleeve is fitted on the outside of each pair of aligned rubber rods, and the two ends of the corrugated sleeve are fixedly connected to the two brake pads respectively.

[0012] Preferably, both ends of the inner side of the caliper are fixedly connected to equally spaced nozzles, and the outer ends of the nozzles are connected to a diverter pipe, with the end of the diverter pipe away from the nozzle connected to a water supply pipe.

[0013] Preferably, the brake disc has annularly distributed arc-shaped isolation strips inside, and annularly distributed arc-shaped water channels on both sides of the brake disc.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This high-efficiency heat dissipation brake pad accessory features an arc-shaped ventilation slot that is concentric with the brake disc, creating a directional airflow channel as the brake disc rotates. This significantly improves air convection efficiency and accelerates heat dissipation from the friction pads. Cooling water is sprayed onto the friction area through nozzles, rapidly reducing surface temperature using the principle of water evaporation and heat absorption. Simultaneously, the water flow washes the ventilation slots and exhaust slots, achieving both heat dissipation and self-cleaning functions. The brake disc's isolation strips agitate the airflow to form vortices, and the water inlet expands the water film contact area. The combined effect of air cooling, water cooling, and structural heat dissipation significantly reduces the risk of heat fade.

[0016] The radial discharge channels and ventilation channels are perpendicularly intersected. Centrifugal force is used to throw friction debris outward along the discharge channels, avoiding blockage and maintaining unobstructed heat dissipation channels. The water flow from the nozzles flows along the channels, removing oil and residual debris, reducing the decrease in braking performance caused by dirt accumulation. The electrode block is contacted and connected by the deformation of the rubber rod, achieving wear limit alarm without the need for external sensors. The structure is simple, low-cost, and highly reliable. The corrugated sleeve seals and protects the electrode block, preventing mud, water, and dust from entering and causing false triggering or circuit failure, making it suitable for complex working environments.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a brake pad accessory with efficient heat dissipation, including a brake disc 1 and a caliper 2. The caliper 2 is installed on the outside of the brake disc 1, and a flange 3 is installed in the middle of the brake disc 1 by bolts. Two symmetrically distributed brake pads 4 are installed inside the caliper 2, and friction blocks 5 are fixedly connected to the side of the two brake pads 4 that are close to each other. The friction blocks 5 have equidistantly distributed ventilation grooves 6 and discharge grooves 7 on their inner sides, and the depth of the ventilation grooves 6 is greater than the depth of the discharge grooves 7. The ventilation grooves 6 are distributed in an arc shape with the same center as the brake disc 1 on the inner side of the friction blocks 5, and the discharge grooves 7 are distributed radially on the inner side of the friction blocks 5, and the discharge grooves 7 and ventilation grooves 6 are perpendicular to each other. Two symmetrically distributed guide rings 8 are fixedly connected to the outside of the brake pads 4, and two symmetrically distributed guide pins 9 are fixedly connected to the inside of the caliper 2, and the guide rings 8 are sleeved on the outside of the guide pins 9 and slide with them. Pistons 10 are fixedly connected to both ends of the caliper 2, and the telescopic ends of the pistons 10 extend into the inside of the caliper 2 and are connected to the brake pads 4.

[0026] The brake disc 1 is bolted to the flange 3 at its center. The exhaust grooves 7 are radially distributed in a straight line and intersect perpendicularly with the ventilation grooves 6, forming a dense mesh-like heat dissipation channel. The flange 3 is used to mount the brake disc 1 to the vehicle wheel hub. During vehicle operation, the wheel will drive the brake disc 1 to rotate. When the vehicle brakes, guide rings 8 are fixedly connected to the outer ends of the brake pads 4. A guide pin 9 is provided at a corresponding position inside the caliper 2. The guide rings 8 are fitted onto the outside of the guide pins 9 and slide against them, ensuring that the brake pads 4 move in a straight line. Pistons 10 are fixedly mounted at both ends of the caliper 2. The telescopic ends of the pistons 10 extend into the caliper 2 and connect to the brake pads 4. When the driver presses the brake pedal, the hydraulic system drives the pistons 10 to extend, pushing the two brake pads 4 towards the brake disc 1, causing the friction blocks 5 to clamp the rotating brake disc 1, achieving braking through friction.

[0027] During braking, the friction block 5 generates a large amount of heat when it comes into contact with the brake disc 1. The arc-shaped structure of the ventilation groove 6 is consistent with the rotation direction of the brake disc 1. When the brake disc 1 rotates at high speed, the airflow accelerates along the arc-shaped path of the ventilation groove 6, forming a directional airflow channel, which quickly carries away the heat inside the friction block 5.

[0028] The radial discharge grooves 7 and ventilation grooves 6 are perpendicularly intersected. On the one hand, the mesh structure increases the contact area between the friction block 5 and the air, enhancing heat dissipation. On the other hand, the debris generated by braking is thrown outward along the discharge grooves 7 with the airflow, avoiding the accumulation of debris that blocks the ventilation grooves 6. The ventilation grooves 6 are relatively deep to ensure sufficient airflow channel volume, while the discharge grooves 7 are relatively shallow to ensure the discharge of debris while avoiding weakening the structural strength of the friction block 5.

[0029] Example 2: Based on Example 1, the following structure is also disclosed: rubber rods 11 are fixedly connected to the inner sides of both brake pads 4, and an electrode block 12 is fixedly connected to the end of the rubber rod 11 away from the brake pad 4. The rubber rods 11 and electrode blocks 12 on the two brake pads 4 are aligned with each other, and a corrugated sleeve 13 is sleeved on the outer side of each pair of aligned rubber rods 11. The two ends of the corrugated sleeve 13 are fixedly connected to the two brake pads 4 respectively. The two ends of the caliper 2 are fixedly connected to the nozzles 14 at equal intervals, and a diversion pipe 15 is connected to the outer end of the nozzle 14. A water supply pipe 16 is connected to the end of the diversion pipe 15 away from the nozzle 14. The brake disc 1 is provided with annularly distributed arc-shaped isolation strips 17 inside, and annularly distributed arc-shaped water inlets 18 are provided on both sides of the brake disc 1.

[0030] The corrugated sleeve 13 is bonded and fixed to the two brake pads 4 at both ends to form a sealed protective structure. The water supply pipe 16 is connected to the vehicle's brake cooling system and can automatically adjust the water supply according to the braking intensity. The curvature of the isolation strip 17 is adapted to the rotation direction of the brake disc 1.

[0031] As the friction block 5 wears down, the distance between the two brake pads 4 gradually decreases, and the rubber rod 11 moves closer to each other, causing the electrode blocks 12 to move closer to each other. When the wear reaches its limit, the electrode blocks 12 make contact and conduction, triggering the vehicle's alarm signal and prompting the replacement of the friction block 5. The corrugated sleeve 13 is made of high-temperature resistant rubber and wraps around the electrode blocks 12 and the rubber rod 11 to prevent dust and mud from entering and causing short circuits or false triggering.

[0032] During braking, the water supply pipe 16 delivers cooling water to the distributor pipe 15, and the nozzle 14 atomizes the water and sprays it onto the contact area between the brake disc 1 and the friction block 5. The water flow forms evaporative cooling on the surface of the friction block 5, and at the same time flows along the ventilation groove 6 and the discharge groove 7, washing away residual debris and oil stains in the groove, thus achieving self-cleaning.

[0033] The arc-shaped structure of the water channel 18 guides the water flow to diffuse along the surface of the brake disc 1, increasing the water film coverage area and accelerating evaporation and cooling. The isolation strip 17 agitates the internal airflow when the brake disc 1 rotates, forming vortices to enhance heat dissipation. The arc-shaped layout of the isolation strip 17 avoids stress concentration and ensures the overall strength of the brake disc 1. The airflow cooling of the ventilation slot 6 and the exhaust slot 7 forms an air-cooled structure. The water mist evaporation of the nozzle 14 absorbs heat to form a water-cooled structure. The airflow disturbance of the isolation strip 17 and the increased surface area of ​​the water channel 18 work together to significantly reduce the risk of brake system thermal fade.
