Automobile hose

Abstract

The invention provides an automobile hose, comprising a rubber inner tube, wherein the rubber inner tube is covered by a stainless steel wire knitted sleeve layer and the stainless steel wire knitted sleeve layer is covered by a nylon wire knitted sleeve layer; rubber of the rubber inner tube is vulcanized and passes through knitting gaps of the stainless steel wire knitted sleeve layer to be adhered to the stainless steel wire knitted sleeve layer and the nylon wire knitted sleeve layer; the stainless steel wire knitted sleeve layer is embedded into the surface of the rubber inner tube, and the stainless steel wire knitted sleeve layer and the nylon wire knitted sleeve layer are adhered by the rubber of the rubber inner tube to form a whole body; and the covering rate of steel wires knitted on the surface of the rubber inner tube is 38-50%. The invention further provides a manufacturing method of the automobile hose. The automobile hose provided by the invention can bear higher work pressure and is flexible in tube body and lighter in weight; the inner tube, the stainless steel wires and the nylon wires are adhered to form a whole body, so that the work pressure is higher and the high-vacuum requirements for the use of racing automobiles can be met; and after the tube body is cut off, the phenomenon that the stainless steel wire knitted sleeve layer and the nylon wire knitted sleeve layer on the section of the hose are scattered does not happen, so that the automobile hose is suitable for being used as the hoses of the racing automobiles.

Description

technical field [0001] The invention relates to a hose for vehicles, in particular to a racing hose. Background technique [0002] Racing hoses basically use detachable joints, so the product size tolerance range is very small. In order to ensure that the joints are easy to assemble, it is required that after the pipe body is cut, the hose section is not allowed to be scattered. [0003] There are two main types of products currently on the market. One is a double-layer stainless steel wire braided reinforced structure racing hose, which can withstand high working pressure. However, due to the difficulty of adhesion and high elasticity of stainless steel wire, After the tube body is cut off, there will be loose flowers on the section of the hose, which will make it difficult to assemble, or the seal will not be good after assembly, resulting in potential quality hazards; the other is a cotton thread plus nylon braided structure, but its working pressure is relatively high. ...

However, due to the difficulty of adhesion and high elasticity of stainless steel wire, After the tube body is cut off, there will be loose flowers on the section of the hose, which will make it difficult to assemble, or the seal will not be good after assembly, resulting in potential quality hazards; the other is a cotton thread plus nylon braided structure, but its working pressure is relatively high. Low, easy to bend and collapse, and the tube body is easy to deform under high vacuum
