Description

Technical Field

[0001] This invention relates to a distributed front engine compartment system for articulated dump trucks, belonging to the field of articulated dump trucks. Background Technology

[0002] Articulated dump trucks are used in narrow, muddy working environments, placing stringent demands on vehicle maneuverability. Therefore, they require a large approach angle and a small front overhang. Furthermore, because articulated dump trucks feature an articulated frame, consisting of independent front and rear frames, the rear frame houses the cargo box and carries the goods, while the front frame primarily supports the engine compartment system and cab. The engine compartment houses the power system, with the engine, transmission, radiator, and other components concentrated there, resulting in very limited space and difficult layout.

[0003] The existing technology features a tandem radiator arrangement in the front engine compartment, with the cooling system located in front of the engine. This results in an excessively long front engine compartment, leading to an excessively long front overhang and a small approach angle, resulting in poor vehicle handling. With the tandem radiator located at the front, airflow over the radiator heats up before entering the front engine compartment and the passenger compartment, causing excessively high engine compartment temperatures, which is detrimental to engine and transmission cooling. Hot air accumulates in the passenger compartment, with a large amount of heat being conducted into the passenger compartment, resulting in poor air conditioning performance and potentially causing thermal aging and failure of some components in the engine compartment. Furthermore, the tandem arrangement is limited by the lateral dimensions of the front of the vehicle, restricting the size of the cooling fan and radiator, making it difficult to improve the cooling system's performance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a distributed front engine compartment system for articulated dump trucks.

[0005] This invention is implemented according to the following technical solution: In a first aspect, the present invention provides a distributed front engine compartment system for an articulated dump truck, comprising: A chassis and a platform system located at the front of the chassis, the platform system including a left-side housing and a right-side housing; The powertrain module includes an engine and a transmission, which are rigidly connected and suspended in the frame.

Vent pipe one is connected to the top of the left radiator, vent pipe two is connected to the top of the engine, and vent pipe three is connected to the right radiator. When the cooling system is working, it can discharge the gas inside into the expansion tank through the vent pipes for storage, thereby regulating the volume change caused by thermal expansion. The bottom of the expansion tank is connected to the engine's water inlet through a water supply pipe to replenish the liquid.

It distributes the radiator and air filter in the front engine compartment, reducing the length of the front engine compartment, reducing the front overhang and approach angle, and increasing the vehicle's passability.

[0016] The technical solution of the present invention is a distributed arrangement, which is not limited to the radiator being placed only at the front of the vehicle.

[0017] The technical solution of this invention adopts the method of exhausting air from the engine compartment to the outside, which can reduce the temperature of the engine compartment and enhance the cooling effect of the air conditioner in the cockpit. Attached Figure Description
