Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an intercooler connection hose connection structure suitable for connecting an intercooler and an engine-side intake conduit in an intercooler mechanism of an automobile or the like.

[Conventional technology]

The connection structure of this type of connection hose requires sufficient consideration to prevent leakage of intake air passing through the connection hose and suction of dust. especially,
If the conduit connected by the connecting hose is subject to relative movement, consideration must be given to prevent the connecting hose from falling off or damaging the connected part. It is desirable that the work be simple.

FIG. 1 shows a connection system for an intercooler in an automobile engine (see, for example, Japanese Utility Model Application No. 57-42122). In the figure, conduits 12 and 14 on the intake inlet side or the intake outlet side are connected to the upper and lower sides of the intercooler 10, and hoses 1 and 14 are connected to the upper and lower sides of the intercooler 10, respectively.
6, 18 to conduits 20, 22. Further, the conduit 20 is connected to a turbocharger 24 of engine E, and the conduit 22 is connected to intake manifolds 26 and 28 of engine E, respectively.

FIGS. 2 and 3 show a hose 18 and a conduit 14,
A conventional example of a connection structure with 22 is shown. still,
The same applies to the connection structure between the hose 16 and the conduits 12 and 20. In the example of FIG.
The ends of the hose 34 are inserted into the opening of the hose 34, and clips 36 and 38 are attached to these parts.

In addition, in the example of FIG. 3, the hose 40 and the conduit 42,
A flange is provided at each end of the bolt 4.
6,48.

[Problems to be Solved by the Invention] However, in the plug-in type shown in FIG. 2, the engine E and the intercooler 10 move relative to each other, so the conduits 30 and 32 tend to come off the hose 34. In addition, in the method shown in Fig. 3, the conduit 4
Although there is no problem when the bolts 2 and 44 are removed from the hose 40, it is necessary to align the holes through which the bolts 46 and 48 are inserted, which reduces work efficiency.

This invention was devised in view of the actual situation,
It is an object of the present invention to provide an intercooler connection hose connection structure that improves the above-mentioned conventional technology and maintains a good connection state and has good workability.

[Means to solve the problem]

In order to achieve such an objective, the present invention provides a connection structure for an intercooler connecting hose that connects an engine side intake system conduit and an intercooler side conduit with a hose, in which the end of the intercooler connecting hose is A cylindrical ring is inserted into the inner periphery, a connecting body having a flange with a trapezoidal cross section is inserted into the outer periphery of the end of the intercooler connection hose into which the cylindrical ring is inserted, and a flange with a trapezoidal cross section is inserted into the end of the conduit. Trapezoidal flanges are provided, a spigot is formed on the contact surfaces of the opposing flanges, an O-ring is interposed, and the joint portions of the flanges are connected with a V-band clamp.

[Effect]

According to the present invention, the intercooler connecting hose absorbs movement between the engine-side conduit and the intercooler-side conduit, and the V-band clamp prevents falling off and prevents leakage of intake air. In addition, when connecting the hose, the spigot provided on the flange functions as a positioner.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5.

FIG. 4 shows an embodiment of the connection structure of the connection hose according to the present invention, and FIG. 5 is a sectional view taken along the line V--V in FIG. 4. In FIGS. 4 and 5, the hose designated by the reference numeral 100 has a cylindrical ring 106 inserted into the inner periphery of the end of a hose member 102 made of silicone rubber, and a cylindrical ring 106 attached to the outer periphery of the end. , a flange 112 formed with a trapezoidal cross section.
A groove 116 into which a sealing ring 114 can be attached is formed on the contact surface of the flange 112, which has a circular outer shape. In the vicinity thereof, a spigot 115 is provided as an opening for a flange 120, which will be described later.

On the other hand, a conduit 11 connected to the hose 100
8 has a flange 11 of the connecting body 108.
2, a circular flange 120 having a trapezoidal cross section is formed.

Such a flange 120 is similar to the flange 112 described above.
The spigot is inserted into a socket provided corresponding to the spigot and comes into contact with the flange 112, and furthermore, a V-band clamp 122 is attached to the outer peripheral edge of the abutting portion of the flanges 112 and 120.
It is installed by 4.

Next, the connection work in the above embodiment will be explained. First, flange 112 and flange 120
Connect the conduit 118 to the connecting body 108 by abutting both contact surfaces of the
match against. In this case, a sealing ring 114 is inserted into the groove 116 in advance. After that, a V is formed on the outer peripheral edges of both flanges 112 and 120.
A band clamp 122 is attached to fix these. The same applies to the other end of the hose 100.

Next, the operation of the above embodiment will be explained.

First, in the hose 100, a hose member 102 made of a flexible member such as silicone rubber is integrated with a connecting body 108, which can absorb relative movement between the conduits, and also allows the flange 112 of the hose 100 and the conduit to be Since the flange 120 of 118 is firmly fixed with the V-band clamp 122, the connecting portion is prevented from falling off, and leakage of intake air can also be prevented. Further, since the flanges 112 and 120 do not require alignment of bolt holes, connection workability is improved without impairing sealing performance.

Also, when connecting the hose 100, the flange 11
The spigot 115 provided at 2 and 120 functions well for positioning.

As explained above, according to this embodiment, the V-band clamp 122 is attached to the outer peripheral edge of the flanges 112, 120 having trapezoidal cross sections to fix both the flanges 112, 120.
This not only simplifies the connection work without compromising sealing performance, but also prevents the connection part from falling off or intake air leakage, and is extremely effective when connecting intercooler connection hoses that have relative movement. It is.

In addition, in this embodiment, the flange 112 is provided with a spigot 115 as a spigot for the flange 120, and the spigot is inserted into a socket on the flange 120 side provided corresponding to the flange 112. , 120 are in contact with each other, positioning when attaching the hose 100 is extremely easy, and work efficiency is dramatically improved.

In addition, when a member such as the sealing ring 114 that is brought into pressure contact for sealing is inserted, if there is no spigot 115 as described above, both flanges 112, 1
20, the ring 114 may fall off,
Also, when positioning, the corners of the flanges 112 and 120 first hit the ring 114, causing the ring 114 to
There was a risk that it would be damaged, but the in-row 11
5 is provided, the spigot 115 serves as a guide for positioning, and the spigot 11
5 hits the other flange 120 first, which has the advantage of eliminating the above-mentioned problem.

[Effects of the invention] As described above, the invention not only simplifies the connection work without impairing the sealing performance compared to the conventional method, but also prevents the connection part from falling off or leaking the intake air. It is extremely effective when connecting intercooler connection hoses.

In addition, this invention has the advantage of providing a spigot on the abutment surface of the flange, making it extremely easy to position the hose and dramatically improving work efficiency, as well as preventing the O-ring from falling off during connection. It has the effect of preventing
