Abstract
The utility model relates to a noise reduction structure for a pressure oil pipe of a steering gear, belonging to the technical field of an automotive power steering system; the noise reduction structure consists of a hard pipe, a pipe sleeve, a pressure hose, a noise reduction pipe and a protective sleeve, wherein one end of the hard pipe is sleeved with the pressure hose by the pipe sleeve in a riveting and pressing way; the noise reduction pipe is arranged in a pipe hole of the pressure hose; one end of the noise reduction pipe is provided with the protective sleeve, and the other end of the noise reduction pipe is riveted with the pressure hose by the pipe sleeve so as to be fixed in an inner hole of the hard pipe. With the adoption of the utility model, the protective sleeve at one end of the prior noise reduction pipe and an inner fixing sleeve and an outer fixing sleeve on the pressure hose are reduced, therefore, the bending deformation of the pressure hose is improved when a car is loaded; moreover, the problems that the bending deformation of the existing pressure hose fails to meet a design requirement when the car is loaded, the oil discharge effect of a product is bad after a pressure test, and the cleanness of the product cannot be guaranteed, are solved. Meanwhile, as the parts of the noise reduction structure for the pressure oil pipe of the steering gear are reduced and the processing technology and production technology are simplified, the cost of the product is decreased to a certain extent.
Description
Technical field
The utility model relates to a kind of commutator pressure oil pipe denoising structure, belongs to automobile power steering systems technology field.
Background technique
Increasingly competitive along with automobile industry improves product structure, improves the product manufacture level, reduces product cost and become the subject matter that each auto parts and components manufacturer pays close attention at present.The noise reduction of existing commutator pressure oil pipe; Because the noise reduction pipe is fixed in the pression hose through the internal fixation cover; The two ends of noise reduction pipe are respectively arranged with protective tube, and the pression hose outer surface is provided with the outer fixing cover, and the rich degree of the song when making the pression hose entrucking has satisfied not designing requirement; Oil extraction weak effect after the product pressure testing detects has simultaneously guaranteed not the turbidity test of product.
Summary of the invention
The purpose of the utility model is: the rich degree of the song when a kind of pression hose entrucking is provided improves, and has improved the product pressure testing simultaneously and has detected back oil extraction effect, has guaranteed the commutator pressure oil pipe denoising structure of product turbidity test.
The utility model is to realize above-mentioned purpose through following technological scheme:
A kind of commutator pressure oil pipe denoising structure; It is made up of hard tube, pipe box, pression hose, noise reduction pipe, protecting jacket; It is characterized in that: hard tube one end is set with pression hose through the pipe box riveting; The noise reduction pipe is housed in the pore of pression hose, and an end of noise reduction pipe is provided with protecting jacket, the other end of noise reduction pipe through pipe box and pression hose riveted fixing in the endoporus of hard tube.
The utility model advantage compared with prior art is:
The noise reduction Guan Yiduan of this commutator pressure oil pipe denoising structure through pipe box and pression hose riveted fixing in the hard tube endoporus; Compared with prior art; Reduced protecting jacket, internal fixation cover and outer fixing cover, and then simplified the producing process of this commutator pressure oil pipe denoising structure, the rich degree of song when having avoided existing pression hose entrucking has satisfied not designing requirement; Oil extraction weak effect after the product pressure testing detects has guaranteed not the problem of product turbidity test.Simultaneously, this commutator pressure oil pipe denoising structure makes product cost that the reduction of certain amplitude arranged because part reduces, producing process is simplified.
Description of drawings:
Accompanying drawing is the schematic representation of commutator pressure oil pipe denoising structure.
Among the figure: 1, hard tube, 2, pipe box, 3, pression hose, 4, protecting jacket, 5, the noise reduction pipe.
Embodiment:
This commutator pressure oil pipe denoising structure is made up of hard tube 1, pipe box 2, pression hose 3, noise reduction pipe 5, protecting jacket 4; Hard tube 1 one ends are set with pression hose 3 through pipe box 2 rivetings; Noise reduction pipe 5 is housed in the pore of pression hose 3; One end of noise reduction pipe 5 is provided with protecting jacket 4, the other end of noise reduction pipe 5 through pipe box 2 and pression hose 3 riveted fixing in the endoporus of hard tube 1.
Noise reduction pipe 5 one ends of this commutator pressure oil pipe denoising structure through pipe box 2 and pression hose 3 riveted fixing in the endoporus of hard tube 1; Compared with prior art; Reduced protecting jacket and the cover of the internal fixation on the pression hose 3 and the outer fixing cover of noise reduction pipe 5 one ends, the rich degree of the song when therefore making pression hose 3 entruckings improves, and has improved the product pressure testing simultaneously and has detected back oil extraction effect; The turbidity test of product have been guaranteed; The rich degree of song when having avoided existing pression hose 3 entruckings has satisfied not designing requirement, and the oil extraction weak effect after the product pressure testing detects has guaranteed not the problem of product turbidity test.Simultaneously, this commutator pressure oil pipe denoising structure makes product cost that the reduction of certain amplitude arranged because part reduces, producing process is simplified.
