Abstract
Description
Technical Field
[0001] The utility model relates to a truck air intake system, in particular to an air intake duct assembly of a heavy truck. Background Art
[0002] The air intake system of heavy trucks is mainly composed of the air intake duct and the paper air filter. In order to better extend the service life of the paper air filter, reduce the number of times the paper filter element is replaced, reduce the cost of vehicle use, and improve the coarse filtration efficiency of the air intake duct so that it has better coarse filtration function, it is the development trend of the air intake system of heavy trucks.
[0003] At present, the intake duct assembly used in heavy trucks has a coarse filtration efficiency of about 30% due to the structure of the intake duct assembly, which is low. Utility Model Content
[0004] A heavy-duty truck air intake assembly improves coarse filtration efficiency by more than 70%, extends the service life of paper air filters, reduces the number of paper filter element replacements, and lowers vehicle operating costs.
[0005] The utility model is realized by the following technical solutions:
[0006] Disclosed is an air intake assembly for a heavy truck. An air intake port 2 with a louver structure is provided on both sides of an air intake housing 1. The interior of the air intake housing 1 is divided into three cavities: an air swirl chamber 3, a dust collection chamber 4, and a filtered air chamber 5. The air swirl chamber 3 is located in the middle of the air intake duct, facing the air intake port 2 with the louver structure. The dust collection chamber 4 and the filtered air chamber 5 are respectively arranged on either side of the air swirl chamber 3. The air swirl chamber 3 has a built-in reverse swirl tube 6, which is arranged horizontally. A detachable dust box 7 is provided at the bottom of the dust collection chamber 4, which is fixed to the bottom of the dust collection chamber 4 by a buckle 8. A dust discharge nozzle 8 is fixed at the bottom of the dust box 7, and dust is discharged by vehicle vibration or manual squeezing of the dust discharge nozzle 8. The lower end of the filtered air chamber 5 is an air outlet 9.
[0007] The main material of the air intake assembly is polyethylene.
[0008] The coarse filtration efficiency of the air intake system of the utility model is relatively improved by 40%. Under the condition that the vehicle usage time remains unchanged and the ambient dust concentration is relatively the same, the service life of the paper air filter is extended. During the cycle of replacing the paper filter element three times originally, the paper filter element only needs to be replaced twice, thus saving the cost of using one set of paper filter elements.

[0012] The utility model is an air intake assembly for heavy trucks, and its structure is as follows: both sides of the air intake housing 1 are provided with an air intake 2 with a shutter structure; the interior of the air intake housing 1 is divided into three cavities: an air swirl chamber 3, a dust collection chamber 4 and a filtered air chamber 5; the air swirl chamber 3 is located in the middle of the air intake, facing the air intake 2 with the shutter structure, and the dust collection chamber 4 and the filtered air chamber 5 are arranged on both sides of the air swirl chamber 3 respectively; the air swirl chamber 3 has a built-in reverse swirl pipe 6, which is arranged horizontally; the lower part of the dust collection chamber 4 is provided with a detachable dust box 7, which is fixed to the lower part of the dust collection chamber 4 by a buckle 8; a dust discharge nozzle 8 is fixed to the lower part of the dust box 7, and the dust is discharged by the vibration of the vehicle or by squeezing the dust discharge nozzle 8 by hand; the lower end of the filtered air chamber 5 is an air outlet 9. (See Figure 1 )
[0013] The air intake assembly is fixed to the cab rear wall 11, with the fixing points at the upper, lower left and lower right parts of the cab rear wall. The air intake assembly is fixed to the cab rear wall 11 through the bracket 12. At the same time, in order to reduce the vibration transmitted from the cab to the air intake assembly, a shock-absorbing rubber block 13 is installed between the bracket 12 and the cab rear wall 11. (See Figure 2 )
[0014] The operating principle is as follows: dust-laden air from the external environment is drawn into the air swirl chamber 3 of the intake duct assembly through the louvered air inlet 2. After being filtered by the built-in swirl tube 6, the dust is separated into the dust collection chamber 4 and discharged through the dust discharge nozzle 8. The clean air enters the filtered air chamber 5 and enters the paper air filter through the air outlet 9.
[0015] (See Figure 3 )
[0016] The main material of the air intake assembly is polyethylene.
[0017] Beneficial effects of the utility model:
[0018] 1. The intake duct assembly is designed with two air intake ports, positive and negative, which increases the intake air flow.
[0019] 2. The air inlet is designed as a shutter structure to effectively prevent rainwater from entering.
[0020] 3. The cyclone tube adopts a reverse cyclone tube structure to ensure that the air intake direction is perpendicular to the axis of the reverse cyclone tube 6, thereby improving the coarse filtration efficiency.
[0021] 4. The integrated box is designed with a detachable structure and is fixed with buckles, which makes it easy to disassemble and clean the dust inside in time.
