High-pressure resistant vibration absorbing hose and manufacturing method of the same

Abstract

The invention relates to a vibration damping tube with high pressure resistance, which seams the connector to be fixed on axial end, wherein it has strengthened vibration damping property, and can confirm flowing speed when transmitting liquid; the invention comprises: an inner surface rubber layer (16), a strengthen layer (18) formed by weave strengthen line with the weaving density not less than 50%; and an outer rubber layer (20) with a connector metallic fitting (14) mounted on the axial end; the seam part (12B) is in extending part; and the weaving angle of strengthen line inside the seam part (18B) and the main part (18A) is set at 55+-2 degrees.

Description

technical field [0001] The present invention relates to a high-pressure shock-resistant hose and a manufacturing method thereof, in particular to such a high-pressure shock-resistant hose, which is preferably used as a hose installed in an engine compartment of a motor vehicle. Background technique [0002] usually. A hose mainly composed of a rubber layer is widely used as an industrial or vehicle hose for various purposes. [0003] The main purpose of using the above-mentioned hose is vibration damping. [0004] For example, in the case of a hose for piping provided in the engine room of a motor vehicle, the hose part absorbs the vibration of the engine, the vibration of the compressor of the air conditioner (in the case of the cooling medium delivery hose, that is, the air conditioner hose) , and various vibrations generated according to the running of the vehicle, the hose is responsible for suppressing the transmission of the vibration from one component connected via...

AI Technical Summary

Problems solved by technology

However, if the thickness of the caulking portion at the axial end portion becomes equal to or thinner than a fixed level due to the expansion, the caulking portion, especially in the inner surface side layer, will occur when caulking and fixing the joint device The problem of caulking and disconnection occurs (in this regard, the hoses disclosed in Patent Document 2 and Patent Document 3 are not based on the method of caulking and fixing the joint device, so the above-mentioned problem does not occur)
