Abstract
The utility model relates to an automobile power steering gear, particularly relates to an easy-to-install steering screw of an automobile power steering gear, and mainly solves the technical problem that a steering screw used by the existing steering gear in the prior art has the defects of complicated structure, poor strength, high production cost and the like. The steering screw comprises a screw body (1) and is characterized in that roller paths (2) are uniformly distributed on the screw body (1); an end head (3) is arranged at one end of the screw body; a connecting head (5) is fixed at the other end of the screw body via a cylindrical section (4); ribs (6) are axially distributed on the outer surface of the connecting head; and a ring slot (7) is arranged on the connecting head.
Description
Technical field
The utility model relates to a kind of automobile power steering, especially relates to a kind of automobile power steering gear steering screw of easy installation.
Background technology
A certain Transmission in steering transmission linkage or the deflector is applied hydraulic pressure or the gas pressure power of different directions, execute hypodynamic a series of parts to help chaufeur, be generically and collectively referred to as power steering.Sedan steering device mechanism relates to road-holding property, stability and the safety of car load, and its quality has also reflected the quality of vehicle, is the critical component that is directly connected to vehicle performance.Chinese patent discloses a kind of automobile power steering (Granted publication number: CN201272396), input shaft and output shaft are housed on its housing, the input shaft first line of a couplet is connected to rack piston, tooth bar and the engagement of fan tooth by having separately between rack piston and output shaft, have a passage at rack piston, in the two-port of passage, respectively be provided with check valve, in the two-port of passage, respectively be connected with a valve seat, check valve includes axostylus axostyle and sliding sleeve, axostylus axostyle penetrates in sliding sleeve, sliding sleeve and valve seat interference fit, axostylus axostyle is positioned at the outer position of sliding sleeve inner port and has the shaft shoulder, against spring is arranged, be fixed with a stop screw that penetrates housing in a side of housing between the axostylus axostyle of two check valves, 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 the middle part be fixed with a guide pin bushing, spring passes from guide pin bushing, the shaft shoulder of axostylus axostyle is circular conical surface towards the side of sliding sleeve, has the through hole that communicates with its inside at the two ends of sliding sleeve.But the steering screw structure that this deflector is used is comparatively complicated, and intensity is relatively poor, and productive costs is higher.
The utility model content
The utility model provides a kind of automobile power steering gear steering screw of easy installation, and it mainly is that to solve the steering screw structure that the existing deflector of prior art uses comparatively complicated, and intensity is relatively 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:
The automobile power steering gear steering screw of easy installation of the present utility model, comprise the screw rod body, be evenly equipped with raceway on the described screw rod body, one end of screw rod body is provided with the termination, the other end of screw rod body is fixed with connector by cylindrical section, the outside face axial distribution of connector has fin, has annular groove on the connector.Whole steering screw can be installed in the power steering by the annular groove on the connector and fin.Raceway on the screw rod body can play the effect of automobile power steering with after nut cooperates.
As preferably, between described screw rod body and the cylindrical section, be provided with transition phase between screw rod body and the termination, the section of transition phase is arc surface.The outside face of transition phase is processed into arc surface, has saved material on the one hand, can increase on the other hand the intensity between transition phase and the screw rod body.
As preferably, the radius of described raceway is 3.3mm.
Therefore, the steering screw structure that the utility model deflector is used is comparatively simple, reasonable, and intensity is higher, and productive costs is lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Parts, position and numbering among the figure: screw rod body 1, raceway 2, termination 3, cylindrical section 4, connector 5, fin 6, annular groove 7, transition phase 8.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the automobile power steering gear steering screw of the easy installation of this example, such as Fig. 1, comprise screw rod body 1, be evenly equipped with raceway 2 on the screw rod body, one end of screw rod body is provided with termination 3, the other end of screw rod body is fixed with connector 5 by cylindrical section 4, and the outside face axial distribution of connector has fin 6, has annular groove 7 on the connector.Between screw rod body and the cylindrical section, be provided with transition phase 8 between screw rod body and the termination, the section of transition phase is arc surface.The radius of raceway is 3.3mm.
During use, whole steering screw is encased in the automobile power steering, and the nut that is threaded at raceway 2 places of screw rod body 1 gets final product.
The above only is specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
Claims (3)
