Abstract
The utility model is a kind of steering gear of monoblock type off-load valve arrangement, including steering gear, rack piston one end of the steering gear is equipped with left lateral journey valve seat, the other end is equipped with right lateral journey valve seat, sleeve is equipped in cavity between left lateral journey valve seat and right lateral journey valve seat, guide rod is equipped in sleeve, spring is cased on guide rod, guide rod is equipped with stroke valve rod in one end of left lateral journey valve seat, stroke valve rod is extended in left lateral journey valve seat, and guide rod, spring and stroke valve rod are integrated into monoblock type off-load valve arrangement by sleeve.The roughness that sleeve lining both ends install at left lateral journey valve seat and right lateral journey valve seat is Ra1.6, and sleeve lining is Ra6.3 with the roughness at stroke valve rod cooperation.The utility model uses monoblock type unloading valve, in terms of set assembling technology, reduces assembly process, accelerates beat, promotes working efficiency, and reduce the risk that neglected loading is brought；For vehicle in unloading process is turned to, ride comfort is more preferable, and the safety for improving vehicle is tested.
Description
Technical field
The utility model is related to the steering gear in auto parts and components, the steering of specifically a kind of monoblock type off-load valve arrangement
Device.
Background technology
What domestic existing recirculating ball power steering gear assembly was subsidiary at present automatically forms unloading valve as split structure, such as schemes
Shown in 1,11 be stroke valve seat one in figure, and 12 be rack piston A, and 13 be stroke valve rod one, and 14 be spring one, and 15 be guide rod
One.I.e. stroke valve seat 1, stroke valve rod 1, spring 1 and guide rod 1 are arranged separately in rack piston A12
Portion.
Split structure is more stringent to the rack piston A12 deep holes requirement of steering gear 10, if size and roughness are overproof,
Vehicle is easily caused to go out phenomena such as turning now to irregularity in unloading process is turned to.Full-vehicle steering irregularity promotes vehicle safety
Property.
Invention content
The utility model promotes vehicle security, spy proposes one in order to which vehicle is made to be smoothed out in unloading process is turned to
The steering gear of kind monoblock type off-load valve arrangement.
The technical solution of the utility model is a kind of steering gear of monoblock type off-load valve arrangement thus, including steering gear,
It is characterized in that：Rack piston one end of the steering gear is equipped with left lateral journey valve seat, and the other end is equipped with right lateral journey valve seat, left stroke valve
Sleeve is equipped in cavity between seat and right lateral journey valve seat, guide rod is equipped in sleeve, is cased with spring on guide rod, guide rod exists
One end of left lateral journey valve seat is equipped with stroke valve rod, and stroke valve rod extended in left lateral journey valve seat, by sleeve by guide rod, spring
Monoblock type off-load valve arrangement is integrated into stroke valve rod.
Further improve is：The roughness that sleeve lining both ends install at left lateral journey valve seat and right lateral journey valve seat is
Ra1.6, sleeve lining are Ra6.3 with the roughness at stroke valve rod cooperation.
Advantageous effect：
The utility model is by split type unloading valve structure assembly in sleeve inner；For rack piston endoporus roughness requirements
It reduces, Ra12.5 is reduced to by Ra6.3；Using monoblock type unloading valve, in terms of set assembling technology, assembly process is reduced, is accelerated
Beat promotes working efficiency, and reduces the risk that neglected loading is brought；For vehicle in unloading process is turned to, ride comfort is more preferable, is promoted
The safety of vehicle, to user brings more preferably usage experience.
Description of the drawings
Fig. 1 is the sectional view that former unloading valve is split structure.
Fig. 2 is the sectional view of the utility model monoblock type off-load valve arrangement.
Fig. 3 is the utility model assembly structure sectional view.
1 is rack piston in figure, and 2 be left lateral journey valve seat, and 3 be stroke valve rod, and 4 be sleeve, and 5 be spring, and 6 be guide rod,
7 be right lateral journey valve seat, and 8 be positioning surface, and 9 be installing port, and 10 be steering assembly, and 11 be stroke valve seat one, and 12 be rack piston

Specific embodiment
The utility model is as shown in Fig. 2/3.
A kind of steering gear of monoblock type off-load valve arrangement, including steering gear 10,1 one end of rack piston of the steering gear 10
Equipped with left lateral journey valve seat 2, the other end is equipped with right lateral journey valve seat 7, is set in the cavity between left lateral journey valve seat 2 and right lateral journey valve seat 7
There is sleeve 4, guide rod 6 is equipped in sleeve 4, is cased with spring 5 on guide rod 6, guide rod 5 is equipped in one end of left lateral journey valve seat 2
Stroke valve rod 3, stroke valve rod 3 are extended in left lateral journey valve seat 2, are collected guide rod 6, spring 5 and stroke valve rod 3 by sleeve 4
It is integrally formed formula structure.
Roughness at 4 inner wall both ends of sleeve installation left lateral journey valve seat 2 and right lateral journey valve seat 7 is Ra1.6,4 inner wall of sleeve
It is Ra6.3 with the roughness at 3 cooperation of stroke valve rod.
1 one end of rack piston in steering gear 10 is equipped with positioning surface 8. and then will be above-mentioned total from installing port 9 when mounted
Into loading.
The utility model uses monoblock type self-unloading valve arrangement, in terms of set assembling technology, is filled by original multiple parts
With one monoblock type unloading valve sub-unit of assembling is changed to, assembly process is reduced, accelerates beat, promotes working efficiency, and reduce
The risk that neglected loading is brought；For vehicle in unloading process is turned to, ride comfort is more preferable, improves the safety of vehicle, is brought to user
More preferably usage experience.
