Abstract

A noise control type intake hose adapted to improve a noise reducing function to increase the productivity and minimize space in the intake system. The noise control type intake hose comprises an intake hose, a hose expanding part formed at a certain portion of the intake hose, an inner cover formed inside the hose expanding part, a wall formed for obtaining a sealed area between the hose expanding part and the inner cover, and an inner hose protruding out from the inner cover to interconnect the inner side of the intake hose and the sealed area.

Description

Noise control type air induction hose
Related application
The preference that the application requires is the korean application submitted on October 7th, 2003 10-2003-0069566 number, and its disclosed content all at this as a reference.
Technical field
The present invention relates to a kind of noise control type air induction hose, be suitable for reducing the noise that air induction hose produces in the vehicle intake system.
Background technique
Usually, the gas handling system of vehicle is used to purify the air that enters motor and suppresses the induction noise that motor produces.
Gas handling system typically is made up of an air induction hose, an air-strainer and an air duct.Yet a defective that exists for the air induction hose of airflow design is that it lacks decrease of noise functions.
Summary of the invention
Embodiments of the invention provide a kind of air induction hose, integrally are formed with a Noise Control Device, are used for improving decrease of noise functions, raise the efficiency thus, and the space of gas handling system is reduced to minimum.
In the preferred embodiment of the invention, noise control type air induction hose comprises the air induction hose of a vehicle intake system.A flexible pipe widening parts is formed on certain part of air induction hose.An inner cover is formed in the flexible pipe widening parts.A spacing wall (wall) is formed and is used for obtaining a closed area between flexible pipe widening parts and inner cover.An inner flexible tube forms from inner cover, makes the inner and closed area interconnection of air induction hose.
Description of drawings
In order to understand characteristic of the present invention and purpose better, be elaborated below in conjunction with accompanying drawing.Wherein:
Fig. 1 illustrates the structure of the noise control type air induction hose of embodiment of the present invention.
Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the noise control type air induction hose of embodiment of the present invention comprises a flexible pipe widening parts 22 of expanding flexible pipe in certain part of air induction hose 20 by predetermined width.An inner cover 24 is formed in the flexible pipe widening parts 22.A spacing wall 26 is formed between flexible pipe widening parts 22 and the inner cover 24 interior section of closed hose widening parts 22.
For make the inboard interconnection of the closed area that forms by spacing wall 26 and air induction hose 20 between inner cover 24 and flexible pipe widening parts 22, inner flexible tube 28 certain part from inner cover 24 on predetermined length is stretched out, towards the interior section of flexible pipe widening parts 22.
If inner flexible tube 28 reaches in the flexible pipe widening parts 22, then reduce the low-frequency noise that air induction hose 20 sends on length.On the other hand, if the length of inner flexible tube 28 is shortened, then reduce the high-frequency noise of air induction hose 20.Therefore, the frequency that preferably will reduce according to relevant air induction hose 20 hope is adjusted the length of inner flexible tube 28.
The flexible pipe widening parts 22, inner cover 24, spacing wall 26 and the inner flexible tube 28 that are contained in the air induction hose 20 are preferred by the formation of molded, unitary ground.
The flexible pipe widening parts 22 of embodiment of the present invention is formed on certain part of gas handling system air induction hose 20.Inner cover 24 is formed in the flexible pipe widening parts 22.Spacing wall 26 is mounted, thereby forms certain closed area between flexible pipe widening parts 22 and inner cover 24.Inner flexible tube 28 stretches out from inner cover 24 and forms a hole thereon, makes the inboard of air induction hose 20 thus and be formed on flexible pipe widening parts 22 interior closed areas to interconnect.
Resonator is played in closed area between flexible pipe widening parts 22 and the inner cover 24, has improved the decrease of noise functions of air induction hose 20 thus.For the decrease of noise functions inner flexible tube 28 that improves low-frequency noise extends on length, and inner flexible tube 28 shortens the decrease of noise functions that improves high-frequency noise on length.
Can change embodiment of the present invention, change, substitute or add, so long as connotation of the present invention and and the scope of claim within.
More than explanation demonstrates, and the air inlet that an advantage of the present invention is air inlet system for vehicle is soft A Guan Zaiqi part is extended, and spaced walls is fixed between expansion flexible pipe inboard and the inner cover, In order to obtain betwixt a closed area. Also be formed with an inner flexible tube, make the closed area and The interconnection of the inboard of air induction hose, the decrease of noise functions of air induction hose of having used simple architecture advances thus.
