Description

Technical Field

[0001] The invention relates to the technical field of solid tires, in particular to a high-heat dissipation solid tire used for mining transport vehicles. Background Art

[0002] In mining and transportation operations, mine haulers, as core equipment, shoulder the heavy lifting of material transport. Due to the complex road conditions in mines, including the presence of gravel and potholes, and the heavy loads and long distances often involved in transportation, extremely high demands are placed on tire performance and reliability. Traditional pneumatic tires are prone to blowouts and punctures in the harsh mining environment, impacting transportation efficiency and safety. Therefore, solid tires, with their high load capacity and strong puncture resistance, have gradually become the mainstream choice for mine haulers.

[0003] However, the solid tires used in existing mining transport vehicles have obvious deficiencies in heat dissipation. Since solid tires do not have the hollow structure of pneumatic tires, they cannot achieve effective heat dissipation through air convection. During mining transportation, the frequent starting and stopping, braking of vehicles, and the intense friction between the tires and the rough ground will generate a large amount of heat. This heat is difficult to dissipate quickly, resulting in a continuous increase in the temperature inside the tire. High temperature will accelerate the aging of the tire rubber material, degrade its performance, and shorten the service life of the tire; at the same time, excessively high temperature will also affect the mechanical properties of the tire, reduce its load-bearing capacity and wear resistance, and increase the safety hazards of vehicle operation. In addition, the structural design of traditional solid tires focuses more on load-bearing performance, and the optimization of the heat dissipation structure is insufficient. The heat dissipation channel is single and the heat dissipation efficiency is low, which is difficult to meet the high-intensity and long-term operation requirements of mining transport vehicles. Therefore, a high-heat dissipation solid tire for mining transport vehicles is proposed to solve the above-mentioned problems. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-8 A high-heat dissipation solid tire for mining transport vehicles includes a tire portion and a brake system portion; the tire portion includes a wheel rim 1, a tread 2 arranged on the outer side of the wheel rim 1, the inner side of the wheel rim 1 is connected to a wheel hub 3, the wheel hub 3 is provided with heat dissipation holes 4, a fixing plate 5, and the fixing plate 5 is provided with a reinforcement plate 6 and a mounting hole 7; a card slot 8 is provided on the inner side of the wheel hub 3, and a reinforcing rib 15 is provided at the connection between the wheel hub 3 and the wheel rim 1, which cooperates with the card slot 8; a graphene heat pipe 9 is installed on the inner side of the wheel rim 1, and the wheel hub 3 is also provided with a heat conduction groove 10 and a connecting groove 11 adapted to the graphene heat conduction pipe 9; The brake system includes a brake disc 12, which is provided with a heat dissipation groove 13. The brake disc 12 is connected to the vehicle through a fixed bracket 14; the brake disc 12 is provided with a mounting hole 2 16, and also includes a sliding frame 17, a pressure pipe 18, a connecting pipe 19, a nozzle 20, an opening and closing cover 21, a storage tank 22, and brake pad 1 23 and brake pad 2 24 adapted to the brake disc 12; the brake system is equipped with a hydraulic cylinder 25, and the pressure pipe 18 is provided with a one-way movable door plate 1 26 and a one-way movable door plate 2 27, and the piston plate 28 in the pressure pipe 18 is connected to the sliding column 29.

[0032] In this embodiment, during vehicle operation, friction between the tire and the ground generates heat. If heat cannot be dissipated promptly, the tire's performance and lifespan will be seriously affected. During operation, the heat generated by friction between the tire and the ground is transferred to the hub 3 through the wheel rim 1. The hub 3, as a key heat dissipation component, has heat dissipation holes 4 evenly distributed on its surface. These holes effectively utilize the airflow generated by the vehicle's operation to dissipate heat from the hub 3 and the surrounding area of the tire, thereby achieving basic heat dissipation. During tire operation, the wheel rim 1 and hub 3 not only withstand pressure from the ground but also generate a large amount of heat due to load and friction. To more efficiently address the heat dissipation issue, a graphene heat pipe 9 is installed inside the tire. Graphene, as a new nanomaterial, has an extremely high thermal conductivity. The internally installed graphene heat pipe 9 can quickly absorb the heat generated by the wheel rim 1 and hub 3 and efficiently transfer the heat to the distribution area of the heat dissipation holes 4 on the hub 3 through the heat conduction path formed by the adapted heat conduction grooves 10 and connecting grooves 11. This heat dissipation design greatly accelerates heat dissipation and significantly improves the stability and safety of the tire under long-term high-speed driving or heavy load conditions.

[0033] In terms of tread design, the tread blocks 2 set on the wheel edge 1 are large and deep, and the grooves are wide. This design performs particularly well on complex roads such as mud, loose soil, and gravel. When the vehicle is driving on these roads, the wide and deep tread blocks can better embed into the ground, forming a larger contact area with the ground, thereby generating strong adhesion. During key operations such as vehicle starting, climbing, and braking, this strong grip can effectively prevent the tire from slipping and improve the vehicle's handling performance. At the same time, the wide and staggered grooves of the tread 2 can quickly discharge mud, water, and debris between the tire and the ground during vehicle driving. For example, when the vehicle is driving on a flooded road, the grooves can quickly squeeze out the accumulated water, avoid slipping due to the adhesion of mud and water, and ensure the vehicle's driving stability under various harsh road conditions.

[0034] The connection structure between the wheel hub 3 and the rim 1 is also optimized. The reinforcing ribs 15 provided on the wheel hub 3 are inserted into the slots 8 opened on the inner side of the rim 1 to form a connection method similar to a mortise and tenon structure. This connection method can effectively disperse the various stresses to which the tire is subjected during driving and enhance the stability of the connection between the rim 1 and the wheel hub 3. In addition, a reinforcement plate 6 is provided at the connection between the rim 1 and the fixed plate 5. The reinforcement plate 6 is made of high-strength alloy material and is tightly connected to the rim 1 and the fixed plate 5 through a special welding process, thereby further enhancing the strength and stability of the overall structure of the tire and ensuring that the tire can operate reliably under various complex road conditions.

[0035] When the vehicle needs to brake, the hydraulic cylinder 25 will quickly output power after receiving the signal from the vehicle control system, driving the brake pad 1 23 and the brake pad 2 24 to move toward the brake disc 12 and clamp it. At this time, the strong friction generated between the brake disc 12 and the brake pad can quickly convert the vehicle's kinetic energy into heat energy, thereby achieving vehicle braking. However, in this process, the brake disc 12 will generate a large amount of heat due to friction. If the heat is not dissipated in time, it will lead to a decline in braking performance and even cause safety hazards. In order to solve this problem, the surface of the brake disc 12 is designed with strip-shaped heat dissipation grooves 13. These strip-shaped heat dissipation grooves 13 increase the heat dissipation area of the brake disc. During the driving process of the vehicle, some heat can be taken away by air flow. At the same time, the brake system is also equipped with a set of advanced cooling medium auxiliary heat dissipation devices. When the brake pad clamps the brake disc, the sliding frame 17 needs to drive the brake pad 2 24 to move. During the movement, the sliding frame 17 will pull the piston plate 28 inside the pressure tube 18 through the sliding column 29, so that the piston plate 28 When the brake is stopped, the sliding frame 17 pushes the piston plate 28 through the sliding column 29, so that the pressure inside the pressure tube 18 increases. At this time, the one-way movable door plate 27 will be pressed and closed, and the one-way movable door plate 1 will rotate open, so that the cooling medium will be sprayed out from the nozzle 20 through the connecting pipe 19 and directly act on the brake disc 12, brake pads and other components. This cooling method can quickly take away the heat from the surface of the brake components, help reduce the temperature of the brake system, and ensure that the braking performance remains stable under conditions such as frequent braking or long downhill driving. In order to ensure the continuous effectiveness of the cooling function, the storage tank 22 can be conveniently replenished with cooling medium through the opening and closing cover 21. The entire cooling system is reasonably designed and easy to operate, which can provide reliable protection for the safe driving of the vehicle.

[0036] Working principle: When the vehicle is running, the tire will generate heat from the friction with the ground, and the heat will be transferred to the wheel hub 3 through the wheel edge 1. The heat dissipation holes 4 evenly distributed on the wheel hub 3 can discharge the heat from the wheel hub 3 and the surrounding of the tire to achieve basic heat dissipation. During the operation of the tire, the heat generated by the wheel edge 1 and the wheel hub 3 due to load and friction is quickly absorbed by the graphene heat pipe 9 installed on the inside, and is efficiently conducted to the heat dissipation hole 4 distribution area on the wheel hub 3 through the heat conduction path formed by the adapted heat conduction groove 10 and the connecting groove 11, thereby accelerating heat dissipation and reducing the overall temperature of the tire. There is a tread 2 on the wheel edge 1. The tread 2 is large and The tread pattern 2 is deep and has wide grooves, which can better embed into the ground on muddy, loose soil, gravel and other roads, generate strong adhesion, and improve the grip of the vehicle when starting, climbing and braking. At the same time, the tread pattern 2 is wide and the staggered pattern grooves can quickly discharge mud, water and debris between the tire and the ground, avoid slipping due to mud and water adhesion, and ensure driving stability. At the same time, a reinforcing rib 15 is provided on the wheel hub 3. The reinforcing rib 15 is inserted into the groove 8 opened on the inner side of the wheel edge 1 to enhance the stability of the connection between the wheel edge 1 and the wheel hub 3, and a reinforcing plate 6 is provided at the connection between the wheel edge 1 and the fixed plate 5, thereby enhancing the stability of the tire during use.

[0037] When the vehicle needs to brake, the hydraulic cylinder 25 receives the control signal and outputs power to drive the brake pad 1 23 and the brake pad 2 24 to move toward the brake disc 12 and clamp it. The friction between the brake disc 12 and the brake pad converts the vehicle's kinetic energy into heat energy to achieve braking. The brake disc 12 generates a lot of heat due to friction. The strip heat dissipation grooves 13 on its surface increase the heat dissipation area, and some of the heat is taken away by air flow. At the same time, when the brake pad is clamped, the sliding frame 17 needs to drive the brake pad 24 to move. When it moves, it will pull the piston plate 28 inside the pressure tube 18 through the sliding column 29, and the internal pressure of the piston plate 28 will decrease, so that the one-way movable door plate 27 moves toward the pressure tube The inner side of 18 opens, and the one-way movable door plate 1 26 will close due to the pressure, thereby extracting the cooling medium stored in the storage tank 22 into the pressure tube 18. When the brake is stopped, the sliding frame 17 will push the piston plate 28 through the sliding column 29 to increase the pressure inside the pressure tube 18, then the one-way movable door plate 27 will be pressed closed, and the one-way movable door plate 1 26 will rotate open, so that the cooling medium will be ejected from the nozzle 20 through the connecting pipe 19, directly acting on the brake disc 12, brake pads and other components, helping to reduce the temperature of the brake system and ensure stable braking performance. The storage tank 22 can be replenished with cooling medium through the opening and closing cover 21 to maintain the cooling function.
