Abstract
The utility model discloses a power steering gear, which comprises a valve spool, a valve sleeve, a steering screw stem and a steering screw nut, wherein the steering screw stem and the valve sleeve are in split structure. Because of utilizing the technical scheme, the steering screw stem and the valve sleeve are in split structure, the steering screw stem and the valve sleeve are respectively processed and then are assembled and used, if the valve sleeve is scraped, the steering screw stem can still be used. The power steering gear is not only convenient in processing, but also reduces cost.
Description
Technical field
The utility model relates to automobile power steering.
Background technology
Ball-and-worm steering system mainly is made up of spool, valve pocket, steering screw, steering nut, housing, sector shaft.The two-stage transmission is generally arranged in the ball-and-worm steering system, and the first order is the bolt and nut transmission, and the second stage is rack tooth fan transmission.Wherein steering screw and valve pocket are generally integral structure, and shortcoming is a complex structure, and cost is higher, and if valve pocket scrap, steering screw can not re-use.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy to process, the power steering of cost-cutting.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: power steering, comprise spool, valve pocket, steering screw and steering nut, and described steering screw and valve pocket are for dividing body structure.
Described steering screw and valve pocket are fixed with straight pin, so that simple in structure.
The utility model is owing to adopted technique scheme, and described steering screw and valve pocket are processed steering screw, valve pocket respectively for dividing body structure, then the two assembling is used, if valve pocket is scrapped, steering screw is also available.Not only easy to process, and cost-cutting.
