Description
Technical field
It the utility model is related to a kind of recirculating ball power steering gear valve assembly, category automobile steering device field.
Background technology
Recirculating ball power steering gear is a kind of transmission device that machine driving is combined with hydraulic drive, is widely used to
All kinds of degree type automobiles.With the development of automobile industry, performance requirement and quality requirement of the user to recirculating ball power steering gear
More and more higher, while in order to better meet requirement of the main engine plants in arrangement to space, ball-and-nut steering gear profile chi
It is very little also to require the more compact of design.Existing recirculating ball power steering gear valve assembly is higher to space requirement, is taken up space
It is larger, have a great impact to the compact designed of steering gear appearance and size.In addition existing steering gear oil groove is arranged on valve body
Inside, there is the problem of valve body difficulty of processing is high, it is impossible to meet the needs of enterprise's production and application.
The content of the invention
The purpose of this utility model is：It is simple low with manufacturing cost to provide a kind of simple in construction, small volume, processing technology
Recirculating ball power steering gear valve assembly.
The technical solution of the utility model is：
A kind of recirculating ball power steering gear valve assembly, it by steering gear valve body, valve pocket, input shaft, steering screw, torsion bar,
Bearing and oil sealing are formed；It is characterized in that：One end of steering gear valve body is movably set with steering screw, the endoporus of steering gear valve body
In by rolling bearing and oil sealing activity input shaft is housed, torsion bar is set with input shaft, between input shaft and steering gear valve body
It is provided with valve pocket；It is connected with each other between valve pocket and steering screw by horizontal pin；Between described input shaft and steering screw
Bearing is provided with, the steering screw of bearing side contacts connection with input shaft by hole clipping.
Described hole clipping is in bowknot shape.
Oil groove is provided with described valve pocket outer circumference surface.
Described bearing is sliding bearing.
The utility model has the advantage of：
The recirculating ball power steering gear valve assembly, the oil groove for being arranged on steering gear valve inner originally valve pocket is arranged on
On outer circumference surface, while employ and steering screw is connected with input shaft in a manner of the hole clipping of bowknot shape and sliding bearing
Connect.After above-mentioned design, the difficulty of processing of the steering gear valve assembly is greatly reduced, improves machining accuracy.In addition this turn
It will be connected with each other to device valve assembly between valve pocket and steering screw by horizontal pin；Solves the use of conventional steering device valve assembly
The problem of space-consuming having during radial direction pin is big, meet the needs that enterprise's processing uses with people.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cross-sectional view of the hole clipping and input axis connection of steering screw of the present utility model.
In figure：1st, steering gear valve body, 2, valve pocket, 3, input shaft, 4, steering screw, 5, torsion bar, 6, bearing, 7, oil sealing, 8,
Rolling bearing, 9, horizontal pin, 10, hole clipping, 11, oil groove.
Embodiment
The recirculating ball power steering gear valve assembly by steering gear valve body 1, valve pocket 2, input shaft 3, steering screw 4, torsion bar 5,
Bearing 6 and oil sealing 7 are formed：One end of steering gear valve body 1 is movably set with steering screw 4, passes through in the endoporus of steering gear valve body 1
Rolling bearing 8 and the activity of oil sealing 7 are equipped with input shaft 3, torsion bar 5 are set with input shaft 3, between input shaft 3 and steering gear valve body 1
It is provided with valve pocket 2；Oil groove 11 is provided with the outer circumference surface of valve pocket 2, the purpose for setting oil groove 11 is：Tradition is arranged on and turned
Oil groove into device valve body 1, the outer circumference surface of valve pocket 2 is arranged on, steering gear valve body 1 can be greatly simplified after being designed using this kind
Processing technology and the steering gear valve assembly assembly technology.
It is connected with each other between valve pocket 2 and steering screw 4 by horizontal pin 9；Using horizontal pin by valve pocket 2 with turning to spiral shell
The purpose that bar 4 connects is：Installing space is saved, makes the structure of steering gear valve assembly compacter.
The bearing 6 of promising sliding bearing is set between input shaft 3 and steering screw 4, and the steering screw 4 of the side of bearing 6 leads to
Cross and contact connection with input shaft 3 in the hole clipping 10 of bowknot shape.
It is using sliding bearing as bearing 6 and the purpose that hole clipping 10 is arranged into bowknot shape：So that steering screw 4
It can be processed with input shaft 3 by the way of cold extrusion, so not only reduce difficulty of processing and also improve processing essence
Degree.
The recirculating ball power steering gear valve assembly, it is simple in construction, processing technology is easy, has not only saved production cost, and
And space-consuming is also reduced, meet the needs that enterprise's processing uses with people.
