Description

Technical Field

[0001] The utility model relates to the technical field of air intake systems, in particular to a front air intake system. Background Art

[0002] At present, the air intake system of trucks in the market generally adopts a rear-type air intake flat pipe structure, which makes it impossible to further increase the volume of the cargo box. At the same time, the system has many parts and long pipes, and it is difficult to significantly improve the air intake efficiency and resistance performance. In the rainy weather in the south, the air filter is easy to get water, resulting in a decrease in the power and economy of the whole vehicle.

[0003] With the emission upgrade, the engine exhaust temperature has further increased. It is difficult to eliminate the heat radiation effect of exhaust by arranging an air filter on the chassis after the vehicle is driven. In addition, the chassis space is becoming more and more compact due to the continuous increase in the volume of the aftertreatment.

[0004] In order to further optimize the overall layout of a truck and improve the performance of an air intake system, the present invention develops a front air intake system solution. Utility Model Content

[0005] In view of the problems existing in the prior art, a front air intake system is needed from the aspects of the layout position and structure of the various components of the air intake system, which fully utilizes the layout space of the whole vehicle and avoids the problem of water ingress through the leaking flat pipe on rainy days.

[0006] The utility model adopts the following technical solution to solve the technical problem: a front air intake system, comprising an air intake flat pipe, wherein the air intake flat pipe is fixed on the front panel and installed inside the front mask, wherein the front mask blocks the air intake port of the air intake flat pipe, and the air intake port takes in air through the gap between the lower part of the front mask and the bumper; the air intake flat pipe is connected to the bellows through a hose clamp, and the bellows is connected to the air filter through an air intake connecting pipe.

[0007] Preferably, the air filter is provided with a tangential air intake structure, which is fixed to the vehicle frame via an air filter bracket.

[0008] Preferably, the air filter is provided with an air filter outlet pipe.

[0009] Preferably, the air filter is provided with a supercharger air inlet pipe, and a supercharger connecting pipe is provided at the end of the supercharger air inlet pipe.

[0010] Preferably, the supercharger air intake pipe is made of PP plastic, and the supercharger connecting pipe is made of AEM rubber.

[0011] The utility model has the following beneficial effects:

[0012] 1) The air filter and pipeline are arranged on the front side of the vehicle, which solves the problem that it is difficult to eliminate the heat radiation effect of exhaust gas when the air filter is arranged on the chassis after the vehicle is driven;

[0013] 2) The air intake flat pipe is fixed on the front panel and hidden inside the front cover. The air intake is blocked by the front cover and air is taken in through the gap between the lower part of the front cover and the bumper, thus preventing dust, debris, rain and snow from entering the air intake system.

[0014] 3) The air intake flat pipe is fixed on the front panel, which does not occupy the rear panel space and increases the volume of the berth or cargo box. BRIEF DESCRIPTION OF THE DRAWINGS
