Description

Technical Field

[0001] This utility model belongs to the field of heavy-duty truck technology, and in particular relates to an integrated water spray tank for heavy-duty trucks. Background Technology

[0002] In the long-haul freight industry, heavy trucks frequently encounter long downhill sections, causing the braking system to operate under continuous high loads. This can easily lead to overheating, performance degradation, or even failure, endangering driving safety. To address this issue, drivers often install water cooling systems to cool the braking system themselves, but this practice presents numerous hidden dangers.

[0003] Regarding regulatory compliance, the self-installed water tank failed to pass vehicle type certification, violating the provisions of the "Technical Conditions for Safe Operation of Motor Vehicles" (GB7258) regarding the modification of external facilities. This causes obstacles in vehicle inspections and other processes, and also poses potential risks to road traffic management.

[0004] Regarding safety hazards, the unauthorized installation of water spray tanks poses a serious problem. Non-standard installations result in insufficient fixing strength; under heavy loads, the intense vibrations can cause the water spray tank to detach, potentially damaging vehicle components and causing accidents. Furthermore, the chaotic piping layout can easily interfere with transmission components, leading to leaks or bursts. Leaks can affect the cooling effect of the braking system, while bursts can damage the electrical system or even cause a fire.

[0005] While integrated fuel tanks exist in existing technologies, such as a diesel engine fuel tank disclosed in CN107143446A, their application differs significantly from that of heavy-duty trucks. In terms of application, this existing technology addresses the internal vibration damping needs of diesel engines, while heavy-duty trucks require solutions for chassis space layout and driving safety. Structurally, this existing technology uses nylon, which cannot withstand the impact loads of heavy-duty trucks and lacks a pressure-resistant structure to prevent fluid sloshing. During heavy-duty truck operation, the fluid inside the tank sloshes violently, and the lack of an effective pressure-resistant structure increases the risk of tank rupture. Furthermore, heavy-duty trucks commonly use aluminum alloy fuel tanks, and nylon does not meet their requirements.

[0006] Therefore, in order to ensure the driving safety of heavy trucks and meet regulatory requirements, it is urgent to develop a compliant integrated oil spraying box specifically for heavy trucks, which can solve the problem that existing technologies cannot meet the actual needs of heavy trucks while ensuring safety.

[0007] In view of the problems existing in the prior art, this utility model provides an integrated water spray tank for heavy trucks.

[0008] This utility model is implemented as follows: an integrated water spray tank for heavy trucks includes a tank body, the tank body being provided with a partition, the partition dividing the tank body into two independent accommodating cavities: an oil tank and a water spray tank; the oil tank has an oil filling port on its upper surface and an oil drain hole on its lower surface; the water spray tank has a water filling port on its upper surface and a water drain hole on its lower surface; the oil tank is provided with at least one first supporting reinforcement plate, the central area of ​​the first supporting reinforcement plate being a concave spherical surface, and the plate being provided with an oil passage hole; the water spray tank is provided with at least one second supporting reinforcement plate, the central area of ​​the second supporting reinforcement plate being a concave spherical surface, and the plate being provided with a water passage hole.

[0013] More preferably, the diameter of the hole located in the connection area of ​​the inner wall of the box is 8~15mm; and the diameter of the hole located in the central concave spherical area is 60~80mm.

[0014] The advantages and technical effects of this utility model are as follows: This utility model achieves compliant integrated application of the water spray tank through a dual-cavity integrated structure and reinforced support design. The core effect is reflected in: Eliminating regulatory risks: Integrating the water tank and fuel tank into the same enclosure as a standard configuration for the entire vehicle complies with vehicle type certification requirements and completely avoids compliance issues caused by unauthorized modifications.

[0015] Enhanced safety and reliability: The concave spherical support reinforcement plate forms an arched pressure-bearing structure, effectively resisting the impact and swaying of fuel and coolant during driving, significantly improving the deformation resistance compared to a flat structure; the independent chamber seal eliminates the risk of oil-water mixing.

[0016] Optimized space and maintenance efficiency: The integrated design saves installation space on the heavy truck chassis and avoids interference from external components with the transmission system; the through holes (oil holes / water holes) on the support plate balance the strength of the box and the fluid flow, and residual liquid can be quickly drained through the bottom drain hole during maintenance.

[0017] In summary, this utility model replaces post-modification with native integration and replaces simple containers with mechanically optimized structures, thus constructing a solution that meets the safety standards of heavy commercial vehicles while ensuring braking and cooling requirements.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0021] Please see Figures 1 to 4 An integrated water spray tank for heavy-duty trucks includes a housing 1, within which a partition 2 divides the housing into two independent chambers: a fuel tank 3 and a water spray tank 4. This integrated design combines the fuel tank and water spray tank into a single unit, saving installation space on the heavy-duty truck and improving space utilization. Simultaneously, the independent chambers prevent cross-contamination between oil and water, ensuring the quality of both the fuel and the water spray, meeting the operational needs of heavy-duty trucks under various conditions, and enhancing the overall performance and reliability of the vehicle.

[0022] The oil tank 3 has an oil filler port 5 on its upper surface and an oil drain hole 6 on its lower surface; the water spray tank 4 has a water filler port 7 on its upper surface and a water drain hole 8 on its lower surface. The oil filler and water filler ports are located on the upper surface, facilitating refueling and water filling operations and improving work efficiency. The oil drain hole and water drain hole are located on the lower surface, allowing for quick and thorough drainage of liquids from the oil tank and water spray tank when needed, preventing residual liquids from corroding the equipment or affecting its future use, thus ensuring the normal operation of the equipment.

[0023] The fuel tank 3 is equipped with at least one first support reinforcement plate 9. The central area of ​​the first support reinforcement plate 9 is concave spherical, and an oil passage hole 10 is provided on the plate. The first support reinforcement plate enhances the structural strength of the fuel tank, enabling it to withstand greater pressure and vibration during vehicle operation, thus improving the durability of the fuel tank. The concave spherical design can disperse stress and reduce the risk of deformation caused by excessive local stress. The oil passage hole ensures the normal flow of oil within the fuel tank, preventing the presence of the support plate from affecting the circulation and supply of oil.

[0024] The water spray tank 4 is equipped with at least one second support reinforcement plate 11. The central area of ​​the second support reinforcement plate 11 is concave spherical, and water passage holes 12 are provided on the plate. The second support reinforcement plate provides additional structural support for the water spray tank, enhancing its stability and preventing damage due to shaking during vehicle operation. The concave spherical structure helps to disperse the impact force of water on the tank body, reducing the risk of tank body breakage. The water passage holes ensure smooth flow of water within the tank body, ensuring timely and uniform spraying when needed, meeting the water spraying requirements of heavy trucks.

[0025] More preferably, the fuel tank 3 is provided with two first supporting reinforcement plates 9, which are arranged parallel to each other between the side walls of the fuel tank 3. The two parallel first supporting reinforcement plates further enhance the structural strength of the fuel tank, enabling it to better withstand various external forces during vehicle operation. This symmetrical arrangement can make the stress distribution inside the fuel tank more uniform, reduce fatigue damage caused by stress concentration, extend the service life of the fuel tank, and improve the safety and reliability of heavy truck operation.

[0026] Preferably, the two first supporting reinforcing plates 9 are symmetrically distributed around their concave spherical surfaces, and the oil passage holes 10 are evenly arranged along the circumference of the concave spherical surfaces. The symmetrical distribution of the concave spherical surfaces allows the two supporting reinforcing plates to form a stable support structure within the oil tank, more effectively dispersing the pressure of the oil on the tank body. The even arrangement of the oil passage holes along the circumference of the concave spherical surfaces ensures more uniform oil flow within the oil tank, avoiding localized oil accumulation or poor flow, thus improving oil circulation efficiency and ensuring a stable oil supply to the engine and other equipment.

[0027] Further preferably, the concave spherical curvature radius R of the first supporting reinforcement plate 9 and the second supporting reinforcement plate 11 satisfies: R = 0.25~0.4 times the width of the housing. Setting the concave spherical curvature radius R to 0.25~0.4 times the width of the housing ensures that the supporting reinforcement plate has sufficient strength while matching it with the structure of the housing. This design allows the supporting reinforcement plate to better adapt to the shape of the housing, reduces stress concentration, and improves the overall stability of the housing. At the same time, it also facilitates the flow of oil and water within the housing, ensuring the normal operation of the equipment.

[0028] More preferably, the oil passage holes and water passage holes are provided in two sets, distributed in the connection area between the first and second supporting reinforcing plates and the inner wall of the housing, and in the central concave spherical region, wherein the diameter of the holes in the central concave spherical region is larger than the diameter of the holes located near the inner wall of the housing. Preferably, the diameter of the holes in the connection area between the oil passage holes and the inner wall of the housing is 8-15 mm; the diameter of the holes in the central concave spherical region is 60-80 mm.

[0029] This technical solution offers the following advantages: Stress Dispersion: Oil and water passages are provided at the connection area between the supporting reinforcement plate and the inner wall of the box, which can disperse the stress generated by the box under impact loads to a certain extent. When liquid flows through these holes, it generates a certain pressure on the hole walls. This pressure distribution helps to balance the stress inside the box, reduce stress concentration, and thus improve the structural stability of the box under the harsh driving conditions of heavy trucks, reducing the risk of box breakage due to excessive stress.

[0030] Weight reduction: By rationally designing the orifice size and distribution, and appropriately increasing the number and adjusting the orifice diameter while meeting the fluid flow requirements, the weight of the box can be reduced to a certain extent. For heavy trucks, this helps reduce the overall vehicle weight, improve fuel economy, and reduce the burden on the vehicle's suspension system and chassis. In complex conditions such as long downhill slopes, stable fluid flow ensures that the braking system is always in good working order, improving driving safety.

[0031] Reducing safety hazards: A well-designed orifice avoids safety hazards caused by poor fluid flow or excessive pressure. For example, it prevents the tank from cracking due to excessive fluid accumulation or affecting the braking system performance due to uneven fluid flow, thereby reducing the probability of traffic accidents.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
