Rear Brake Hose-L/R-Front Section
Automobile brake hose (commonly known as brake pipe) is a component used in the automobile braking system. Its main function is to transfer the brake medium in the automobile brake to ensure that the braking force is transmitted to the automobile brake shoe or brake caliper. Generate braking force so that braking is effective at any time.
In addition to the pipe joints in the brake system, it is used to transmit or store the hydraulic pressure, air pressure or vacuum degree for the application of the brakes of the vehicle.
jacket
A protective device attached to the outside of a hose to increase its resistance to scratches or impacts.
brake hose assembly
This is the brake hose with a fitting. Brake hoses are available with or without a jacket.
free length
The length of the exposed portion of the hose between two couplings on the hose assembly in a straight line.
brake hose connector
In addition to the clamp, a connection piece attached to the end of the brake hose.
Permanently Connected Fittings
Fittings connected by crimping or cold extrusion deformation, or fittings with damaged bushings and ferrules, are required to be replaced every time the hose assembly is reinstalled.
burst
A malfunction that causes the brake hose to become detached from the fitting or to leak.
Vacuum Line Connector
Refers to a flexible vacuum transmission conduit:
a) In the brake system, it is a connector between metal pipes;
b) No pipe joints are required for installation;
c) When assembled, its unsupported length is less than the total length of the part containing the metal pipe.
Test conditions
1) The hose assembly used for the test should be new and aged for at least 24 hours. Keep the hose assembly at 15-32°C for at least 4 hours before the test;
2) For the hose assembly for flexural fatigue test and low temperature resistance test, all accessories, such as steel wire sheath, rubber sheath, etc., must be removed before being installed on the test equipment.
3) Except for high temperature resistance test, low temperature resistance test, ozone test and hose joint corrosion resistance test, other tests must be carried out at room temperature within the range of 1 5 - 3 2 °C.
Hydraulic Brake Hoses, Hose Fittings and Hose AssembliesEdit
structure
The hydraulic brake hose assembly consists of brake hoses and brake hose connectors. There is a permanent connection between the brake hose and the brake hose joint, which is achieved by crimping or cold extrusion deformation of the joint part relative to the hose.
performance requirements
The hydraulic brake hose assembly or corresponding parts, under the above test conditions, should be able to meet the various performance requirements specified in this article when tested according to the following method.
Inner bore throughput after constriction
