Abstract
The utility model discloses a kind of high strength deflector steering screw, comprise screw body, it is characterized in that described screw body is evenly equipped with raceway, one end of screw body is provided with termination, the other end of screw body is fixed with connector by cylindrical section, the outside face axial distribution of connector has fin, and the angle between the adjacent surface of adjacent lugs is 90 °.Main application of the present utility model is that a kind of structure is comparatively simple, rationally, intensity is higher, the high strength deflector steering screw that productive costs is lower in order to provide.
Description
Technical field
The utility model relates to a kind of automobile power steering, especially relates to a kind of high strength deflector steering screw.
Background technology
Transmission a certain in steering transmission linkage or deflector is applied to hydraulic pressure or the gas pressure power of different directions, to help chaufeur to execute hypodynamic a series of parts, be generically and collectively referred to as power steering.Sedan steering device mechanism relates to the road-holding property of car load, stability and safety, and its quality also reflects the quality of vehicle, is the critical component being directly connected to vehicle performance.Chinese patent discloses a kind of automobile power steering (Authorization Notice No.: CN201272396), input shaft and output shaft its housing be equipped with, input shaft is connected with rack piston, tooth bar by having separately between rack piston with output shaft engages with fan tooth, rack piston has a passage, respectively check valve is provided with in the two-port of passage, a valve seat is respectively connected with in the two-port of passage, check valve includes axostylus axostyle and sliding sleeve, axostylus axostyle penetrates in sliding sleeve, sliding sleeve and valve seat interference fit, the position that axostylus axostyle is positioned at outside sliding sleeve inner port has the shaft shoulder, against there being spring between the axostylus axostyle of two check valves, the stop screw that one penetrates housing is fixed with in the side of housing, stop screw is aimed at the axostylus axostyle of an adjacent check valve, the two-port of valve seat and passage is thread connection, passage middle part be fixed with a guide pin bushing, spring passes from guide pin bushing, and the shaft shoulder of axostylus axostyle is circular conical surface towards the side of sliding sleeve, has the through hole communicated with its inside at the two ends of sliding sleeve.But the steering screw structure that this deflector uses is comparatively complicated, and intensity is poor, and productive costs is higher.
Summary of the invention
The utility model is to provide a kind of high strength deflector steering screw, and its steering screw structure mainly solving the deflector use existing for prior art is comparatively complicated, and intensity is poor, the technical matters that productive costs is more high.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of high strength deflector steering screw of the present utility model, comprise screw body, described screw body is evenly equipped with raceway, one end of screw body is provided with termination, the other end of screw body is fixed with connector by cylindrical section, the outside face axial distribution of connector has fin, and the angle between the adjacent surface of adjacent lugs is 90o.Whole steering screw can be installed in power steering by the fin on connector.After raceway on screw body and nut screw connection, the effect of automobile power steering can be played.
As preferably, described fin is inner is arc surface with the junction of cylindrical section, can ensure the Joint strenght between whole connector and cylindrical end like this.
As preferably, the outer end of described termination is provided with chamfering, is conveniently encased in automobile power steering by whole steering screw.
Therefore, the steering screw structure that the utility model deflector uses is comparatively simple, rationally, intensity is higher, and productive costs is lower.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1.
Parts, position and numbering in figure: screw body 1, raceway 2, termination 3, cylindrical section 4, connector 5, fin 6, arc surface 7, chamfering 8.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of high strength deflector steering screw of this example, as shown in Figure 1, Figure 2, have a screw body 1, screw body is evenly equipped with raceway 2, one end of screw body is provided with termination 3, and the outer end of termination is provided with chamfering 8.The other end of screw body is fixed with connector 5 by cylindrical section 4, and the outside face axial distribution of connector has fin 6, and the angle between the adjacent surface of adjacent lugs is 90o.Fin is inner is arc surface 7 with the junction of cylindrical section.
During use, whole steering screw is encased in automobile power steering, and at the raceway 2 place threaded coupling nut of screw body 1.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
