CN203476541U - Air cleaner for automobile air intake system - Google Patents

The utility model provides an air cleaner for an automobile air intake system. The air cleaner comprises an upper shell with an air outlet pipe, wherein the air outlet pipe is connected with an air outlet pipe component; at least a first boss or at least a second groove is arranged on the outer periphery of the air outlet pipe; at least a first groove or at least a second boss is arranged on the inner pipe wall of the air outlet pipe component; the first boss is matched with the first groove, or the second groove is matched with the second boss. The air cleaner effectively solves the problem that in the moving process of an automobile, the air outlet pipe component of the air cleaner is detached from the air outlet pipe of the air cleaner due to vibration at various degrees, meets the requirements of users, and improves the safety.

A kind of air-strainer for automobile air inlet system

Technical field

The utility model relates to a kind of air-strainer for automobile air inlet system.

Background technique

Motor car engine is the heart of automotive engineering machinery, and gas handling system is the artery of motor car engine, and its function is to provide clean, dry, sufficient air for motor.

Automobile air inlet system, primary clustering is comprised of air cleaner assy, air-cleaner snorkel road assembly, air-strainer outlet pipe assembly and crankcase bleed pipe, its design and installation will directly affect the performance of the duty of engine, the stability of work, reliability, working life and the feature of environmental protection.Reasonably structural design can also reduce car load noise, makes fuel oil fully burn to reduce oil consumption.Another mouth of pipe of air-strainer outlet pipe assembly is connected with motor car engine, and clean, dry, sufficient air enters motor by outlet pipe assembly.

Air cleaner assy is connected with air-strainer steam outlet pipe assembly, and uses larynx banding solid.The project organization that air cleaner assy of the prior art is connected with air-strainer steam outlet pipe assembly is straightway.This structural imperfection is due to automobile vibrations in various degree in actual travel process, causes air-strainer steam outlet pipe assembly to be easy to and air cleaner assy is thrown off, and is not well positioned to meet user's usage requirement, and Safety performance is not high.

Model utility content

The technical problems to be solved in the utility model is the defect of easily throwing off on air-strainer steam outlet pipe assembly and air cleaner assy steam outlet pipe in prior art in order to overcome, and a kind of constitutionally stable air-strainer for automobile air inlet system is provided.

The utility model is to solve above-mentioned technical problem by following technical proposals:

A kind of air-strainer for automobile air inlet system, it comprises that one has the upper shell of a steam outlet pipe, described steam outlet pipe is connected with a steam outlet pipe assembly, its feature is, the outer periphery of described steam outlet pipe are provided with at least one the first boss or at least one the second groove, the inner tubal wall of described steam outlet pipe assembly is provided with at least one the first groove or at least one the second boss, and described the first boss and described the first groove match, or described the second groove and described the second boss match.

Preferably, described the first boss or described the second boss are a bar.

Preferably, the end of described boss is circular arc, taper or trapezoidal.

Preferably, on described steam outlet pipe assembly, be also provided with a larynx hoop.Fastening lower steam outlet pipe assembly at larynx hoop is tightr with being connected of upper shell steam outlet pipe.

Preferably, on described steam outlet pipe assembly, be also provided with a flowmeter.

Preferably, described steam outlet pipe assembly is provided with a crankcase bleed pipe.

Preferably, described air-strainer also comprises a lower shell body, and described upper shell and described lower shell body are fixing up and down, and on described lower shell body, are also provided with a suction tude assembly.

Preferably, described steam outlet pipe and described connecting tube are made by ethylene propylene diene rubber (EPDM), nitrile butadiene rubber (NBR) and any one material of polyoxyethylene (PVC).

Positive progressive effect of the present utility model is: the utility model has effectively solved the problem of throwing off on air-strainer steam outlet pipe assembly that automobile causes due to vibrations in various degree under steam and air-strainer steam outlet pipe, meet user's requirement, improved Security.
