Description

Technical Field

[0001] This utility model belongs to the field of vehicle braking technology, specifically a braking and cooling device for heavy-duty vehicles. Background Technology

[0002] Heavy-duty vehicles, due to conditions such as full load and long downhill slopes, generate a large amount of heat rapidly through friction between the brake discs and pads. Under extreme conditions, the temperature can reach over 800-1000℃, causing two major problems: First, the brake friction coefficient decreases, leading to "heat fade" and increasing the risk of brake failure. Second, it accelerates brake disc cracking and pad carbonization, shortening lifespan and increasing maintenance costs. Existing cooling methods use direct water spraying, which cools down quickly, but the high-temperature brake discs experience severe thermal shock when exposed to cold water, easily causing them to break. Furthermore, the water flow can easily pollute the road surface and freeze at low temperatures. In contrast, natural air cooling is inefficient when using simple air cooling, while forced air cooling requires power, has limited installation space, and the fan is prone to damage under harsh conditions.

[0003] CN109080598A discloses a heat dissipation device for a vehicle braking system. The heat dissipation device includes a hollow shell with air inlets on both sides of the top, a drive assembly inside the hollow shell, and air supply assemblies on both sides of the front of the hollow shell. The air supply assemblies include cylindrical air shrouds on both sides of the front of the hollow shell with gradually decreasing diameters at their outer ends, and L-shaped air supply hoses on the outer ends of the cylindrical air shrouds. The proposed heat dissipation device for a vehicle braking system has a simple structure and low cost. It can be controlled by the vehicle's own power supply and has excellent ventilation and heat dissipation performance. When installed on the vehicle chassis, it can effectively reduce the temperature of components such as brake hubs, brake pads, and brake wheel cores, thereby ensuring the normal operation of the vehicle braking system and improving driving safety, achieving very ideal technical results.

[0004] This device ensures the normal operation of the vehicle braking system and improves driving safety by using air supply components located on both sides of the front of the hollow shell. However, this device relies on passive air cooling, which still cannot improve its heat dissipation effect. Therefore, a heavy-duty vehicle brake cooling device is proposed, which uses atomized water in combination with air cooling to dissipate heat from the brake disc bearings, thereby avoiding excessive thermal stress that could lead to breakage and improving the heat dissipation effect.

[0005] To address the problems mentioned in the background section, this utility model provides a brake cooling device for heavy-duty vehicles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heavy-duty vehicle brake cooling device, comprising a cooling box, an air inlet on the outside of the cooling box, an air outlet pipe connected to the bottom of the cooling box, a protective cover fixed to the outside of the cooling box, a cooling mechanism installed inside the cooling box, and a spray mechanism provided inside the cooling box. The heat dissipation mechanism includes a servo motor, a first gear, and a second gear. The servo motor is fixed inside the heat dissipation box, and the first gear is fixed to the rotating end of the servo motor. The second gear is rotatably connected inside the heat dissipation box. The spray mechanism includes a water tank, a third gear, and a connecting rod. The water tank is located inside the heat dissipation box, the third gear is rotatably connected to the inside of the heat dissipation box, and the connecting rod is fixed to the outside of the third gear.

[0008] Preferably, there are two sets of the second gear and the fan, which are symmetrically distributed about the central axis of the heat sink box. The fan has a fan blade inside, and a second gear is fixed to one end of the fan blade.

[0009] Preferably, a baffle is fixed to the outside of the connecting rod, a delivery pipe is opened inside the heat dissipation box, and an atomizer is fixed inside the heat dissipation box.

[0010] Preferably, there are two sets of the third gear and the connecting rod, which are symmetrically distributed about the central axis of the heat sink box. Several sets of teeth are fixed on the outside of the third gear, and the third gear and the second gear mesh with each other.

[0011] Preferably, the spoilers are arranged in several groups, and the spoilers are arranged in a circular array about the central axis of the connecting rod. The bottom end of the water tank is connected to a delivery pipe. The atomizers are arranged in several groups, and the atomizers are symmetrically distributed about the central axis of the delivery pipe. The atomizers are arranged at equal intervals.

[0012] Preferably, the air inlets are provided in several groups, and the air inlets are arranged at equal intervals. The air outlets are provided in two groups, and the air outlets are symmetrically distributed about the central axis of the heat sink box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the combination of a water storage tank, a third gear, and a connecting rod, enables the device to use atomized water to assist in heat dissipation, avoiding thermal shock damage to the brake disc and ensuring a stable water supply. Water in the storage tank is transported to the atomizer via a delivery pipe. After atomization, the water comes into contact with the brake disc with the cool airflow, utilizing water vapor evaporation to absorb heat and enhance the heat dissipation effect. Furthermore, the atomized water avoids the risk of cracks caused by cold water directly impacting the high-temperature brake disc. The second gear drives the third gear, the connecting rod, and the baffle to rotate. The baffle creates turbulence in the water in the storage tank, ensuring a continuous flow of water into the delivery pipe and guaranteeing continuous atomized heat dissipation.

[0014] This invention, through the coordinated arrangement of a servo motor, a first gear, and a second gear, enables the device to achieve efficient forced air cooling, rapidly reducing the temperature of the braking system of heavy-duty vehicles. The servo motor drives the first gear to rotate, which in turn drives two sets of second gears and a fan to rotate synchronously. The fan blades draw in cold air from the air inlet and blow it directionally onto the brake disc bearing through the air outlet, forming a continuous forced airflow that accelerates heat dissipation. This avoids the problem of insufficient efficiency of simple passive air cooling and effectively alleviates brake fade. Attached Figure Description

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.

[0018] like Figures 1 to 7 As shown, this utility model provides a brake cooling device for heavy-duty vehicles, including a cooling box 1. The cooling box 1 has an air inlet 2 on its outside. The bottom of the cooling box 1 is connected to an air outlet 3. A protective cover 4 is fixed to the outside of the cooling box 1. A cooling mechanism 5 is installed inside the cooling box 1. A spray mechanism 6 is provided inside the cooling box 1. Several sets of air inlets 2 are arranged at equal intervals. Two sets of air outlet 3 are arranged symmetrically about the central axis of the cooling box 1.

[0019] The above solution allows air to enter the fan 504 through the air inlet 2 and then pass through the air outlet 3. An air delivery hose is fixed to the outside of the air outlet 3, and its output end is aligned with the bearing of the brake disc, so that the brake disc bearing is cooled by air when the device is started.

[0020] like Figures 1 to 6 As shown, the heat dissipation mechanism 5 includes a servo motor 501, a first gear 502, and a second gear 503. The servo motor 501 is fixed inside the heat dissipation box 1. The first gear 502 is fixed to the rotating end of the servo motor 501. The second gear 503 is rotatably connected inside the heat dissipation box 1. A fan 504 is fixed to the outside of the second gear 503. Several sets of teeth are fixed to the outside of the first gear 502 and the second gear 503. The first gear 502 and the second gear 503 are meshed together. There are two sets of second gears 503 and fan 504. The second gear 503 and fan 504 are symmetrically distributed about the central axis of the heat dissipation box 1. Fan blades are provided inside the fan 504. The second gear 503 is fixed to one end of the fan blades.

[0021] The above solution is adopted: by starting the servo motor 501 to drive the first gear 502 to rotate, the first gear 502 rotates and drives the second gear 503 and the fan blades of the fan 504 to rotate, and then the fan blades take in air from the air inlet 2 and blow it to the air outlet duct 3, so as to cool the brake disc bearing.

[0022] like Figures 1 to 7As shown, the spray mechanism 6 includes a water tank 601, a third gear 602, and a connecting rod 603. The water tank 601 is located inside the heat dissipation box 1. The third gear 602 is rotatably connected inside the heat dissipation box 1. The connecting rod 603 is fixed to the outside of the third gear 602. There are two sets of the third gear 602 and the connecting rod 603. The third gear 602 and the connecting rod 603 are symmetrically distributed about the central axis of the heat dissipation box 1. Several sets of teeth are fixed to the outside of the third gear 602. The third gear 602 and the second gear 503 are meshed together.

[0023] like Figures 1 to 7 As shown, a baffle 604 is fixed to the outside of the connecting rod 603, a conveying pipe 605 is opened inside the heat dissipation box 1, an atomizer 606 is fixed inside the heat dissipation box 1, several sets of baffles 604 are arranged in a ring array about the central axis of the connecting rod 603, the bottom end of the water storage tank 601 is connected to the conveying pipe 605, several sets of atomizers 606 are arranged symmetrically about the central axis of the conveying pipe 605, and the atomizers 606 are arranged at equal intervals.

[0024] The above solution involves starting the servo motor 501 to drive the fan 504 for air cooling, while simultaneously starting the atomizer 606 to atomize the water inside the delivery pipe 605 and spray it towards the air intake of the fan 504. This allows the atomized water to come into contact with the brake disc bearings along with the air, thereby cooling the brake disc and preventing deformation caused by a sudden drop in temperature. Furthermore, the rotation of the second gear 503 synchronously drives the third gear 602, the connecting rod 603, and the baffle 604 to rotate. When the baffle 604 rotates, it turbulents the water source inside the water tank 601, ensuring a continuous flow of water into the delivery pipe 605 and guaranteeing a continuous water supply.

[0025] The working principle and usage process of this utility model are as follows: By starting the servo motor 501, the first gear 502 is driven to rotate. When the first gear 502 rotates, it drives the second gear 503 and the fan blades of the fan 504 to rotate. The fan blades then draw in air from the air inlet 2 and blow it into the air outlet duct 3, which cools the brake disc bearing. When the servo motor 501 drives the fan 504 for air cooling, the atomizer 606 is simultaneously activated to atomize the water inside the delivery pipe 605 and spray it towards the air inlet of the fan 504. The atomized water comes into contact with the brake disc bearing with the air, thereby cooling the brake disc and preventing deformation caused by a sudden drop in temperature. The rotation of the second gear 503 can synchronously drive the third gear 602, the connecting rod 603, and the baffle 604 to rotate. When the baffle 604 rotates, it turbulents the water source inside the water storage tank 601, allowing the water source to continuously enter the delivery pipe 605 and ensuring a continuous water supply.
