The power steering oil hose includes an oil inlet hose and a return oil hose fixed opposite to the oil inlet hose, and the oil return hose is further divided into a main return oil hose and a secondary oil return hose.
Oil inlet hose
Working pressure: 10-15Mpa,
Executive Standard: SAE J188
Oil return hose
Working pressure: <0.5Mpa
Executive Standard: SAE J189
The main structure is as follows:
The oil inlet hose (9) and the oil return hose (8) fixed opposite to the oil inlet hose (9) are characterized in that the oil return hose (8) is divided into a main return oil hose (5) and a second time. Oil hose (2), one end of the main oil return hose (5) and one end of the secondary oil return hose (2) are connected through a return oil hose (4), and the secondary oil return hose (2 the other end and the steering gear (1) The oil outlets are connected.
Function: The power steering hose is used to provide steering oil to the steering gear to achieve the purpose of reducing steering resistance. The pipe is usually made of NBR.
The precautions for power steering hoses are as follows:
1. The return hose length is preferably 20mm~500mm. If the oil return hose is too short, the assembly is inconvenient and the torsion amplitude is insufficient. The oil return hose is too long, and there is a problem that the knot is easy to knot and the oil passage is not smooth. Therefore, it is necessary to select a suitable length.
2. The oil return hose and the main oil return hose are fixed by clamps. It can ensure the sealing between the main oil return hose and the return oil hose, and also facilitate the disassembly and assembly between them.
