Description

Technical Field

[0001] This utility model relates to the field of front-end chassis layout of vehicle frames, and more specifically, to a chassis layout structure and vehicle for engineering vehicles. Background Technology

[0002] The condenser is a crucial component of the cooling system in heavy-duty vehicles. Heavy-duty truck condensers are typically located at the front of the vehicle, in contact with the atmosphere, utilizing the cooling effect of the atmosphere to dissipate heat from the coolant through the fins. Engineering vehicles have a wide range of applications covering vast areas. In high-temperature regions, such as tropical and subtropical areas, traditional cooling methods are clearly insufficient. Many vehicles experience frequent air conditioning compressor failures, especially in summer, with some compressors lasting only 6-12 months, causing significant inconvenience to users. Therefore, improving the condenser's heat dissipation efficiency and extending the lifespan of the air conditioning compressor without altering the front-end environment of the vehicle frame is of paramount importance.

[0003] The disadvantages of existing technical solutions are that, in tropical and subtropical regions, they still cannot meet the heat dissipation requirements of the condenser during the hot summer months, and the air conditioning compressor is prone to damage and requires regular maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a chassis layout structure for engineering vehicles. By optimizing the structural layout, it can match the condenser electric fan, improve the heat dissipation effect, and reduce the probability of damage to the air conditioning compressor of the engineering vehicle.

[0005] Another objective of this invention is to provide a vehicle that, through optimized structural layout design, can be matched with a condenser electric fan to improve heat dissipation and reduce the probability of damage to the air conditioning compressor of the engineering vehicle.

[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Example 1

[0035] Reference Figures 1-4 This embodiment provides a chassis layout structure for an engineering vehicle, which includes a front suspension casting 2, a cooling module 3, a front traction beam 5, an electric fan 6, a front underrun protection 8, and a condenser 9. It is arranged at the front end of the frame assembly 1, and the cooling module 3, the front suspension casting 2, the front traction beam 5, the condenser 9, the electric fan 6, and the front underrun protection 8 are arranged sequentially from top to bottom.

[0036] Specifically, the front suspension castings 2 are arranged on the left and right sides of the frame assembly 1, and the front suspension castings 2 are fixed to the frame assembly 1 by bolts.

[0037] The front suspension casting 2 refers to the casting installed in the suspension system at the front of a car, primarily used to support the vehicle body and absorb road impacts. The front suspension casting 2 is part of the car's suspension system, mainly installed at the front of the vehicle to support the body and absorb shocks and vibrations from the road surface. The front suspension casting 2 is typically made of metal materials, commonly including cast iron and aluminum alloys. Cast iron is hard but has poor toughness, while aluminum alloys offer higher strength, rigidity, and stability.

[0038] The cooling module 3 is arranged at the front end of the frame assembly 1 and above the front suspension casting 2, and is connected and fixed to the front suspension casting 2 via a radiator bracket 4. The cooling module 3 is the core system for regulating the engine operating temperature. Its main function is to dissipate the heat generated by the engine in a timely manner through the radiator, in conjunction with components such as the electric fan 6 and the water pump, ensuring that the engine operates within a suitable temperature range.

[0039] Specifically, the front traction beam 5 is arranged in front of the cooling module 3, and the front traction beam 5 is fixed to the front suspension casting 2 by bolts.

[0040] The condenser 9 is arranged in front of the cooling module 3, and the condenser 9 is fixed to the cooling module 3 by the condenser bracket 11.

[0041] The front lower guard 8 is arranged at the front end of the frame assembly 1 and located below the front suspension casting 2, and the front lower guard 8 is fixed to the front suspension casting 2 by the front lower guard bracket 7.

[0042] The electric fan 6 is positioned at the front end of the condenser 9 and is fixed to the condenser 9 via a fan bracket 10. This arrangement of the electric fan 6 makes full use of the front space of the vehicle frame, and its modular design facilitates installation, inspection, and maintenance, offering good versatility. The fan bracket 10 utilizes mounting holes on the condenser 9 for fixing, also featuring a modular design and good versatility, making it suitable for most engineering vehicle models.

[0043] The electric fan 6 of the car condenser 9 is an important component of the car's air conditioning system. Its main function is to dissipate heat into the air through high-speed rotation, thereby lowering the temperature of the condenser 9 and ensuring the normal operation of the air conditioning system. The electric fan 6 is usually controlled by a temperature control switch, and the fan will automatically start when the interior temperature reaches a certain value.

[0044] The design and installation of the electric fan 6 can also be optimized to reduce assembly weight and assembly difficulty. In this embodiment, a gap of at least 20 mm is left between the electric fan 6 and the front traction beam 5, and a gap of at least 60 mm is left between the electric fan 6 and the front lower guard 8.

[0045] The conductive wire harness 13 of the electronic fan 6 runs close to the upper outer edge of the electronic fan 6, and is fixed to the electronic fan 6 by multiple clips. Specifically, when fixing the conductive wire harness 13 with clips, the clips can be used to fix it to the electronic fan 6 at 100mm intervals. This routing of the conductive wire harness 13 is more reasonable and prevents the wires from crossing and getting tangled.

[0046] An electronic fan 6 is mounted on a fan bracket 10, which has multiple fan mounting slots. Each fan mounting slot can accommodate one electronic fan 6. When multiple electronic fans 6 are arranged, the fan mounting slots are arranged in parallel to ensure that the multiple electronic fans 6 are located on the same plane after installation. This allows for the arrangement of a larger diameter and a greater number of electronic fans 6 within a limited space, resulting in better heat dissipation.

[0047] One end of the conductive wire harness 13 is electrically connected to the electronic fan 6, and the other end is provided with an electronic fan connector 12. The electronic fan connector 12 is arranged inside the front traction beam 5 and is used to mate with the cab wiring harness connector to establish a connection with the cab main control system. The electronic fan 6 connector is arranged inside the front traction beam 5, which provides high safety and good waterproof performance.

[0048] This design utilizes the remaining space at the front of the chassis to rationally arrange the front suspension casting 2, cooling module 3, front traction beam 5, electric fan 6, front underbody protection 8, and condenser 9. This maximizes the heat dissipation efficiency of the condenser 9, reduces the burden on the air conditioning compressor, and features a compact and rational layout with good versatility. It is suitable for the front-end environments of most engineering vehicles. Even if not the factory configuration, users can easily and conveniently add the electric fan 6 themselves. This layout can match the condenser 9 and electric fan 6, improving heat dissipation and reducing the probability of damage to the air conditioning compressor in engineering vehicles. This design provides a beneficial chassis layout structure for engineering vehicles exported to tropical and subtropical regions and operating in high-temperature summer environments, and can be widely promoted in similar engineering vehicles.
