Description

Technical Field

[0001] The present invention belongs to the technical field of the power assist system of special vehicles, and particularly relates to an air intake device for the air supply system of special vehicles. Background Art

[0002] The engine is the core part of the power system of special vehicles, and the air supply system, as an auxiliary system of the engine, plays a crucial role. It can filter out dust and debris in the intake air, ensure clean air enters the engine, and at the same time provide filtered clean air for the air compressor. Usually, the outside dusty air enters the intake device and then enters the air filter through a pipeline, and enters the engine after one-stage or multi-stage filtration.

[0003] The traditional intake device is grid-shaped and has no shielding around it. It is mostly used in external environments without splashing water, and is not suitable for harsh working conditions with a lot of sand and dust, strong winds, and a lot of water. When a tracked special vehicle quickly passes through a waterlogged section, a large amount of water will be splashed. At this time, the splashed water has a high speed and a high position. For the traditional intake device, the water is very likely to splash into the intake pipeline from the side and enter the engine through the air filter, affecting the life of the engine. At the same time, the traditional intake device cannot prevent the sand and dust blown by strong winds from entering the air filter from the side of the intake device, thus shortening the maintenance cycle of the air filter. Therefore, it is necessary to design an intake device that can effectively solve the above problems. Summary of the Invention
