Abstract
The utility model relates to the field of automobile steering systems, and in particular relates to a steering high-pressure oil pipe. A high-pressure oil pipe with a function of reducing steering noise comprises a pump end metal hard pipe, a pump end rubber hose, a middle metal hard pipe, a middle rubber hose and a steering gear end metal hard pipe, which are sequentially connected in the flowing direction of steering fluid and connected through sleeves; an oil inlet threaded pipe joint is arranged at an oil inlet of the pump end metal hard pipe; an oil outlet threaded pipe joint is arranged at an oil outlet of the steering gear end metal hard pipe; and a silencing pipe is sleeved in each of the pump end rubber hose and the middle rubber hose. Through the high-pressure oil pipe, vibration of the system is greatly reduced; and the silencing pipes are sleeved in the rubber hoses, and one end of each silencing pipe is fixed on the oil inlet side of each rubber hose, so that the steering noise is effectively reduced, and the high-pressure oil pipe has significance for improving the reliability of a steering system and the comfort of a driver.
Description
Technical field
The utility model relates to the automotive steering field, relates in particular to a kind of high pressure fuel pipe that turns to.
Background technology
The radical function that turns to high pressure fuel pipe is to turn to fluid to deflector from the hydraulic steering pump transmission, guarantees line seal, reduces vibration and the noise of hydrostatic steering system.Exist in the pressure duct pressure higher turn to liquid, under some special operation condition, easily produce the noise of similar " groan ".If that uses turns to high pressure fuel pipe inappropriate, will significantly increase the vibration of system, and so that noise is very large, not only be unfavorable for guaranteeing the steering swivel system reliability of operation, also can the traveling comfort with chaufeur be impacted.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high pressure fuel pipe that reduction turns to the noise function that has, this high pressure fuel pipe uses flexible pipe to link to each other with oil pump, be set with hush pipe in the rubber tube, effectively reduce turning to noise, significant for the traveling comfort of the reliability that improves steering swivel system and chaufeur.
The utility model is achieved in that a kind of high pressure fuel pipe that reduction turns to the noise function that has, comprise the pump end metal hard tube that links to each other in turn according to the moving direction of diverted flow, pump end rubber tube, the intermetallic metal hard tube, intermediate rubber flexible pipe and deflector end metal hard tube, described pump end metal hard tube, pump end rubber tube, the intermetallic metal hard tube, link to each other by sleeve between intermediate rubber flexible pipe and the deflector end metal hard tube, the oil inlet of described pump end metal hard tube is equipped with the oil inlet screwed union, on the oil outlet of described deflector end metal hard tube the oil outlet screwed union is housed, also is set with hush pipe in pump end rubber tube and the intermediate rubber flexible pipe.
Described hush pipe is fixedly mounted on the oil inlet end in pump end rubber tube and the intermediate rubber flexible pipe.
The Length Ratio of described hush pipe and pump end rubber tube is 1:3 ~ 3:4.
The Length Ratio of described hush pipe and intermediate rubber flexible pipe is 1:3 ~ 3:4.
Described sleeve is the riveted sleeve.
The utlity model has reduction and turn to the high pressure fuel pipe of noise function to use flexible pipe to link to each other with oil pump, and between two sections hard tubes, be provided with rubber tube, significantly reduced system vibration; Also be set with hush pipe in rubber tube, one of hush pipe is fixed on the oil-feed side of rubber tube, effectively reduces turning to noise, and is significant for the traveling comfort of the reliability that improves steering swivel system and chaufeur.
