＜産業上の利用分野＞
本考案はインタークーラー結合用ホースに関す

送つている。<Prior art> In an internal combustion engine equipped with a turbocharger, the air supplied from the compressor is high in temperature due to compression and the exhaust temperature transmitted from the exhaust turbine. A cooler, or intercooler, is installed, and low-temperature supply air cooled by the intercooler is sent to the internal combustion engine.

給気は圧力を有しているためにゴムホースの結合
は強固に行うことを必要とする。 By the way, when connecting the compressor to the intercooler and the intercooler to the intake pipe up to the intake manifold, the internal combustion engine to which the turbocharger is attached and the intercooler are connected by rubber hoses because they vibrate relative to each other. Relative vibrations must be absorbed. Also,
Since the supply air has pressure, the rubber hose must be firmly connected.

端と外端とのオーバラツプ部分における締付力に
よる補強布の切断が発生するので、この点を配慮
する必要性がある。 In addition, the rubber hose must be strong enough not to burst due to the internal pressure of the supplied air. As a rubber hose that has strength against internal pressure, one in which reinforcing cloth is embedded in a circumferential spiral shape within a thick cross section is known. However, when such rubber hoses are connected, the reinforcing fabric may be cut due to the tightening force at the overlapped portion between the spiral inner end and the outer end of the reinforcing fabric, so it is necessary to take this into consideration.

渦巻状となる。<Problems to be Solved by the Invention> The factors that cause the reinforcing fabric to break in the conventional rubber hose will be explained. In manufacturing this type of rubber hose, as shown in FIG.
As shown in Figure B, the material is rolled into a cylindrical shape and then vulcanized. When the cylinder is shaped like a glue roll, it becomes a layered spiral corresponding to the thickness of the rubber plate 11, but by vulcanization, the contact surfaces of the layered rubber plates become fused and integrated, and there are no fault lines. , only the reinforcing cloth 10 has a spiral shape within one thick cross section.
しかしながら、第７図で示すように、ゴム板１

となつていた。 However, as shown in FIG.
There is a step corresponding to the thickness of the rubber plate 11 between the spiral inner end 10b of the reinforcing cloth 10 at the beginning of winding and the spiral outer end 10a of the reinforcing cloth 10 at the end of winding.
The overlap width l2 between 0a and the spiral inner end 10b was large, and therefore the wall thickness at the overlap width l2 portion was large.

させるのである。 When such a rubber hose 4 is connected by tightening the outer diameter of the rubber hose 4 with a connecting ring 6 as shown in FIG. 6, the overlap width l2 is compressively deformed because the wall thickness is larger than other parts. The amount is larger than other parts. Furthermore, since the overlap width is large, there is no place for the rubber to escape, and the compressive deformation acts as a shearing force.As a result, the reinforcing fabric 10 at the overlap width l2 is cut, degrading the strength of the hose 4.

プ幅を小さくして成るものである。<Means for solving the problems> The present invention improves the above-mentioned conventional problems, and its characteristic structure is that the device fits into the outer diameter of the cylindrical part formed on the flange that connects to the conduit of the intercooler. In a rubber hose that is clamped and connected using a joining ring, and in which a reinforcing cloth is buried in a circumferential spiral shape within a thick cross section, a circumferential spiral is attached to the outer end of the reinforcing cloth at the joining end of the hose. A notch is provided to reduce the overlap width between the spiral outer end and the spiral inner end of the reinforcing cloth.

切断がなくなる。<Function> With the above configuration, when the outer diameter of the hose end is tightened with the coupling ring, the thick wall at the overlap width area between the spiral outer end and the spiral inner end of the reinforcing cloth is transferred to the other thin wall section. Moreover, since the overlap width is small, the amount of escape is also small, and there is no need to cut the reinforcing fabric.

Reference numeral 5 denotes a flange which is joined to the flange 3 of the conduit 2 by tightening bolts, and the flange 5 is integrally formed with a cylindrical portion 7 into which the inner diameter of the hose 4 is fitted. A trapezoidal convex portion 8 is provided on the outer periphery of this cylindrical portion 7 . Reference numeral 6 denotes a coupling ring that is fitted onto the outer circumferential surface of the end of the hose 4 fitted into the cylindrical portion 7 and mechanically caulked in the radial direction with a die. A trapezoidal recess 9 corresponding to the projection 8 is provided on the inner circumference of the coupling ring 6, and the hose 4 including the recess 9 and the projection 8 is provided between the coupling ring 6 and the cylindrical portion 7. It is a type of clamping connection.

A notch 12 in the circumferential direction is provided in the spiral outer end 10a of the reinforcing cloth 10 at the end of the hose that is clamped and connected by the cylindrical portion 7 and the spiral outer end 10a and the spiral inner end 10.
The configuration is such that the overlap width l1 with b is small,
The spiral outer end 10c and the spiral inner end 10b of other parts

In addition, the amount of rubber wall thickness wrap is reduced. Therefore, the amount of stretching flow due to the compression of the rubber wall thickness that occurs when the coupling ring 6 is caulked can be suppressed to a small extent, and the reinforcing cloth 10 is not cut. The reinforcing cloth 10 tries to stretch to follow the increase in the thickness of the rubber, but the reinforcing cloth 1
There is a limit to the amount of stretching of 0, and it does not try to stretch in the same way as rubber. Therefore, as described above, by reducing the overlap width l1 , the stretching flow during compression of the rubber is reduced, and the cutting action of the reinforcing fabric 10 is suppressed. Furthermore, since the overlap width l1 of the compressed portion is small, there is no variation in wall thickness during caulking, and uniform clamping can be achieved.

In addition to maintaining the strength of the hose, it is possible to obtain a connection that ensures airtightness by reducing variations in wall thickness at the overlapping width portion.
