Abstract
The utility model provides an automobile high-pressure oil pipe with a noise reduction structure, which belongs to the technical field of automobiles and solves the problems that the pulsation of an oil pump and the self-excited vibration of high-pressure oil in a conversion valve generate noise when the present pressure assistance system works. The automobile high-pressure oil pipe with the noise reduction structure includes a rubber pipe positioned at the middle, and drainage pipes connected at two ends of the rubber pipe; pipe joints are arranged at outer ends of the drainage pipes; at least one section of metal spiral pipe is arranged in the rubber pipe; a middle sleeve is arranged between the rubber pipe and the metal spiral pipe; the metal spiral pipe penetrates the middle sleeve so as to be positioned through the middle sleeve; and the middle sleeve is tightly matched and connected with the rubber pipe. The utility model can change the oil liquid rhythmical and vibrated laminar flow structure into turbulence, eliminate amplitude, and greatly attenuate vibratory energy, so as to suppress noise transmission.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of vehicle high-pressure oil pipe with noise-reducing structure.
Background technique
Along with the extensive use of automobile and the raising of levels of user sophistication, the user improves gradually to the requirement of steering system idle noise, when the hydraulic booster system in the auto steerer was worked, the self-excited vibration meeting that the pulsation of oil pump and high pressure oil cause in switching valve produced noise; Under the lower situation of the Q of hydraulic element such as employed pump, valve itself, noise is bigger; Go back neither one at present and well eliminate the way of this noise, car in motion, noise passes in the car, and the people is had the fidgets.
Summary of the invention
The purpose of this utility model is at existing deficiency, and a kind of vehicle high-pressure oil pipe with noise-reducing structure that can abate the noise is provided.
The purpose of this utility model can realize by following technical proposal: a kind of vehicle high-pressure oil pipe with noise-reducing structure, comprise sebific duct that is in the middle part and the drainage tube that is connected described sebific duct two ends, the outer end of described drainage tube is provided with pipe joint, it is characterized in that, be provided with at least one section metallic coil in the described sebific duct, be provided with middle cover between described sebific duct and the metallic coil, described metallic coil runs through described middle cover and makes it obtain the location by this middle cover, and described middle cover is connected with described sebific duct drive fit.
Originally the vehicle high-pressure oil pipe that has noise-reducing structure mainly is made up of sebific duct and drainage tube, be socketed with above-mentioned drainage tube at the two ends of sebific duct, outer end at drainage tube has pipe joint, be installed with at least one section metallic coil by middle cover in sebific duct, the fluid in the sebific duct can only pass through in metallic coil.
In above-mentioned vehicle high-pressure oil pipe, also be lined with one deck sheath between described middle cover and the described sebific duct with noise-reducing structure.This sheath is between middle cover and sebific duct and have an effect of anti-vibration.
In the above-mentioned vehicle high-pressure oil pipe with noise-reducing structure, described sheath adopts sponge material to make.Sponge material has the effect of sound-absorbing anti-vibration.
In the above-mentioned vehicle high-pressure oil pipe with noise-reducing structure, described middle cover is cylindric, and its outside becomes to have the groove of annular.This middle cover is fixed in the sebific duct by this annular groove.
In the above-mentioned vehicle high-pressure oil pipe with noise-reducing structure, the two ends of described metallic coil have filler opening and oil outlet respectively.Flow out from the oil outlet of metallic coil again from the filler opening inflow of metallic coil at the sebific duct inner fluid.
Compared with prior art, originally have in the sebific duct in the vehicle high-pressure oil pipe of noise-reducing structure and be provided with at least one section metallic coil, be provided with middle cover between sebific duct and the metallic coil, metallic coil runs through described middle cover and makes it obtain the location by this middle cover, middle cover is connected with described sebific duct drive fit, when the hydraulic oil of oil pump outflow passes through metallic coil, the laminar flow structural change of the rhythmical vibration of fluid can be become turbulent flow, subdue amplitude, moreover high frequency amplitude and wavelength are absorbed by metallic coil, the energy of vibration is greatly decayed, thereby has suppressed the transmission of noise.
