As a component in the automobile braking system, the main function of the automobile brake hose is to transmit the braking medium in the automobile braking, so as to ensure that the braking force is transmitted to the automobile brake shoes or the brake caliper to generate the braking force, so that the brake can be braked at any time. efficient.
In a general brake system, the lines usually appear near the master cylinder and the wheels. But these two kinds of pipes are different: several black pipes extending from the brake master cylinder, these pipes are made of metal, the metal has no elasticity, and will not expand due to the increase of the pressure of the liquid, ensuring the braking force. transfer. However, at the end of the pipeline, that is, near the wheel, a hose has to be used, because the suspension of the vehicle is always moving relative to the body during driving. At present, the brake hose used in many cars is still made of rubber. The outer casing is covered with a steel wire braided tube, which can improve the high pressure resistance.
The hydraulic brake hose assembly consists of a brake hose and a brake hose connector. The brake hose and the brake hose connector are permanently connected, and the connection is realized by crimping or cold extrusion deformation of the connector part relative to the hose. The hydraulic brake hose assembly or the corresponding parts, under the above test conditions, shall be able to meet the performance requirements specified in this article when tested according to the following methods.
The brake hoses sold on the market are all brake hose assemblies with joints. According to the different forms of automobile braking, it is divided into hydraulic brake hose, pneumatic brake hose and vacuum brake hose. According to its different materials, it is divided into rubber brake hose and nylon brake hose.
The rubber brake hose has the advantages of strong tensile strength and easy installation, but the disadvantage is that the surface is easy to age after long-term use. Nylon brake hose has the advantages of anti-aging and corrosion resistance. The disadvantage is that in the case of low temperature, the tensile strength is weakened. If it is impacted by external force, it is easy to break.
