Abstract
The invention belongs to the field of high-pressure oil pipes of automobile power steering pipes, and particularly relates to a noise reduction structure for an automobile power steering pipe, which comprises a rubber oil pipe, two ends of the rubber oil pipe are connected with a metal pipe respectively through oil pipe joints, two metal hoses are arranged in the rubber oil pipe, a baffle plate is arranged in the rubber oil pipe, at least one oil through hole with a large middle and two small end openings is arranged on the baffle plate, a plurality of elliptical oil holes are arranged on the metal hoses, each oil hole is provided with an oil stopping plate fixed onto the edge of the oil hole, and the oil stopping plates are fixed onto the metal hoses and extend towards the upper sides of the oil holes. The noise reduction structure has the advantages that high-pressure oil flowing out of the oil holes on the metal hoses is scattered and separated by the aid of the oil stopping plates to enter the rubber oil pipe so that noise is reduced, the high-pressure oil is compressed, expanded and compressed again by the oil through holes of the baffle plate to enter the next metal hose through the oil holes similarly after scattered by the baffle plate, and the noise of the pressure oil pipe is reduced.
Description
Technical field
The invention belongs to the high-pressure oil pipe field of automobile power steering tube, specifically is a kind of automobile power steering tube denoising structure.
Background technique
One is made up of the steering pump high-pressure oil pipe of automobile the metal joint at rubber oil hose and two ends, and rubber oil hose is fixedly connected with metal joint through sleeve pipe.When motor turning, by high-pressure service pump output turn to liquid through high-pressure oil pipe the time because high pressure and laminar flow, high-pressure oil pipe can send bigger noise.A kind of disclosed on the Chinese patent document " denoising structure of automobile oil pipe "; Its notification number is: CN200975583Y; It includes the oil-feed sebific duct; In sebific duct, be placed with metal harmony pipe, metal harmony pipe is the helix structure that is formed spring-like by the metal wire rod helically coiling, and metal harmony pipe is locked on the metal tube termination of inserting sebific duct.High pressure oil flows out in the slit through metal harmony Guan Houcong helix structure, is that the high pressure oil of laminar flow originally becomes turbulent flow, thereby can reduces noise.Because the metal harmony pipe in the oil-feed sebific duct is to be formed by a wires material helical coiling; Therefore the shape and structure in slit is identical between the two joint spirals, thereby causes the flow direction of the high pressure oil that from the slit, flows out consistent, thereby can not make high pressure oil form turbulent flow effectively; And then influence its noise reduction; Afterwards for address this problem occurred like the disclosed notification number of Patent Office of the People's Republic of China be: the name of CN 201720301U is called " denoising structure of steering pump of automobile high-pressure oil pipe ", but because this denoising structure practical effect is not very good, and long service life; Therefore, also not too adapt to the quiet comfortable demand of present high-grade automobile.
Summary of the invention
The problem that the present invention will solve is big, the uncomfortable shortcoming of the high-pressure oil pipe noise of existing automobile power steering tube, and a kind of automobile power steering tube denoising structure is provided.
The invention provides following technological scheme:
The automobile power steering tube denoising structure, it comprises rubber oil hose, these rubber oil hose two ends are connected with metal tube through oil connection respectively; Be provided with two metallic hoses in the rubber oil hose, be provided with a baffle plate in the described rubber oil hose, have an oil through on the baffle plate at least; This oil through is the little oil through of two open ends broad in the middle; Described metallic hose is provided with some oilholes, and oilhole ovalize, each oilhole are provided with an oil-choking plate that is fixed on the oilhole limit; Oil-choking plate is fixed on the metallic hose, and extends to the oilhole top.
Described oil-choking plate is made as the willow leaf shape.
Comprise two oil throughs on the described baffle plate, oil through is little rugby ball shape in two broad in the middle or rhombus.
Advantage of the present invention is to break up separate to get in the rubber oil hose and reduce noise through the high pressure oil that the metallic hose upper oil hole is come out that is provided with of oil-choking plate; Then the oil through by baffle plate carries out the next metallic hose of compression-expansion recompression back entering to high pressure oil; Disperse the back to get into metallic hose by baffle plate equally, thereby reduce the noise of pressure oil pipe by oilhole.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the automobile power steering tube denoising structure, it comprises rubber oil hose 1; These rubber oil hose 1 two ends are connected with metal tube 3 through oil connection 2 respectively, are provided with two metallic hoses 4 in the rubber oil hose 1, are provided with a baffle plate 5 in the described rubber oil hose 1; Have an oil through 5a on the baffle plate 5 at least, this oil through 5a is the little oil through of two open ends broad in the middle, and described metallic hose 4 is provided with some oilhole 4a; The oilhole ovalize; Each oilhole 4a is provided with an oil-choking plate 4b who is fixed on the oilhole limit, and oil-choking plate 4b is fixed on the metallic hose 4, and extends to oilhole 4a top.
Wherein, oil-choking plate 4b is made as the willow leaf shape.
Wherein, comprise two oil through 5a on the baffle plate 5, oil through is little rugby ball shape in two broad in the middle or rhombus.
