Description
Technical field
It the utility model is related to a kind of air filter assembly, more particularly to a kind of heavy-duty car air filter assembly.
Background technology
Air filter assembly is the necessary devices on heavy-duty car, because heavy-duty car works in the poor environment of road conditions mostly
In, when heavy-duty car travels, car body jolts, it is larger to tremble, and to ensure structural stability, air filter in air filter assembly and goes out
Tracheae needs firmly connection；In the prior art, an extension, the inlet end of escape pipe are set typically at the gas outlet of air filter
Be socketed on extension, then with anchor ear by escape pipe cuff on extension；The problem of existing be：Suitable for foregoing setting side
The escape pipe of formula, its shape are generally the tubular body structure of standard, i.e., the sectional dimension on escape pipe everywhere is almost identical, and
The air inlet port dimensions of escape pipe and the gas outlet size of air filter are also almost identical；With the development of technology, taken on heavy-duty car
The device of load is more and more, and in order to improve the utilization rate of vehicle body space, my company develops a kind of escape pipe of new construction, and this goes out
Tracheae is polymorphic structure, and the air inlet port dimensions of escape pipe are much larger than the gas outlet size of escape pipe, the size in the middle part of escape pipe from
To gradually narrowing at gas outlet at air inlet, and structure is more flat at the air inlet of escape pipe, if still using existing setting
Mode sets the escape pipe of new construction, it is impossible to ensure the connective stability of air filter and escape pipe, and due to escape pipe
Structure is more flat at air inlet, and anchor ear setting is very difficult, and operation is very inconvenient.
Utility model content
The problem of in background technology, the utility model proposes a kind of heavy-duty car air filter assembly, including sky
Filter and escape pipe, the air inlet of the escape pipe connect with the gas outlet of air filter；Its improvement is：The escape pipe enters
Gas port size is much larger than the gas outlet size of escape pipe；The escape pipe is made up of interconnected connecting portion and guide section, institute
State air inlet to be located on the lower surface of connecting portion, star-like flange disk and first annular projection are provided with connecting portion lower surface；Institute
State that first annular raised position is corresponding with the port position of air inlet, the star-like flange disk is positioned at first annular raised outer
Enclose, first annular projection is raised from star-like flange side surface；The gas outlet is located on the upper surface of air filter, air filter
The second annular protrusion and Duo Gen connecting poles are provided with upper surface；The position of second annular protrusion and the port position of gas outlet
Put correspondingly；The connecting pole is located at the outside of the second annular protrusion, the position of more connecting poles with it is multiple on star-like flange disk
The position of connecting hole corresponds；The external diameter of second annular protrusion is less than first annular raised internal diameter；Second convex annular
Rising and be socketed in first annular projection, more connecting poles are socketed in multiple connecting holes on star-like flange disk correspondingly,
Screwed hole is provided with connecting pole upper surface, is locked between connecting pole and star-like flange disk by bolt.
After the utility model, escape pipe is connected by star-like flange disk with air filter, and connective stability is preferable, and
Assembly manipulation is very convenient.
Advantageous effects of the present utility model are：A kind of heavy-duty car air filter assembly is proposed, the air filter is total
Air filter in is connected with escape pipe with flange method, and installation operation is very convenient, and its connective stability is preferable.

Embodiment
A kind of heavy-duty car air filter assembly, including air filter 1 and escape pipe 2, air inlet and the sky of the escape pipe 2
The gas outlet connection of filter 1；Its improvement is：The air inlet port dimensions of the escape pipe 2 are much larger than the gas outlet chi of escape pipe 2
It is very little；The escape pipe 2 is made up of interconnected connecting portion 2-1 and guide section 2-2, and the air inlet is located at connecting portion 2-1's
On lower surface, star-like flange disk 2-3 and first annular raised 2-4 are provided with connecting portion 2-1 lower surfaces；It is described first annular convex
Rise 2-4 position it is corresponding with the port position of air inlet, the star-like flange disk 2-3 is located at first annular raised 2-4 periphery,
First annular raised 2-4 is raised from star-like flange disk 2-3 end faces；The gas outlet is located on the upper surface of air filter 1, air filter
The second annular protrusion 1-2 and Duo Gen connecting pole 1-1 is provided with the upper surface of device 1；The position of the second annular protrusion 1-2 with
The port position of gas outlet is corresponding；The connecting pole 1-1 is located at the second annular protrusion 1-2 outside, more connecting pole 1-1 position
Put and corresponded with the position of multiple connecting holes on star-like flange disk 2-3；The external diameter of the second annular protrusion 1-2 is less than the
One annular protrusion 2-4 internal diameter；Second annular protrusion 1-2 is socketed in first annular raised 2-4, and more connecting pole 1-1 are one by one
