Abstract
The utility model provides an integrated precisely-sealed noise-free bidirectional oiling device, which overcomes the defects that presently, most oiling devices of power-assisted steering cylinders are non-compact in structure, high in noise, high in temperature, easy to leak oil and the like. The integrated precisely-sealed noise-free bidirectional oiling device comprises a body 1, a secondary polyurethane lip dust ring 2, a hydrogenated nitrile butadiene rubber spiral lip seal ring 3, a composite retainer 4, a piston rod 5, a G-shaped ring 6 and a cylinder block 7. The secondary polyurethane lip dust ring is mounted in an annular groove, the hydrogenated nitrile butadiene rubber spiral lip seal ring is mounted in a sealed annular groove, the composite retainer is mounted in a larger shoulder hole, and the oiling device assembly is fixed with the cylinder block through the G-shaped ring. The integrated precisely-sealed noise-free bidirectional oiling device different from original oiling device fixed by flange faces is compact in structure and simple in mounting, and arrangement space and total weight of the cylinder are reduced simultaneously.
Description
Technical field
The utility model relates to a kind of automobile, construction machinery and equipment parts, especially relates to a kind of to the isostructural improvement of steering jack oiling device.
Background technology
In medium and heavy automobile steering system, enough light at present for the power that makes the pilot control bearing circle, all be furnished with steering jack usually, with assisted diversion.The present following problem of the employed oil cylinder ubiquity of each vehicle: 1) the oiling device structure is not compact, normally leans on flange face and cylinder barrel to carry out bolted connection, has so just increased the oad and the weight of part, not only wasting space but also be unfavorable for alleviating of complete vehicle weight; 2) can produce noise in various degree during through oiling device when fluid, cause oily temperature rise, waste of power; 3) the fluid phenomenon that leaks outside is general between oiling device and piston rod, contaminated environment.
The utility model content
The utility model provides a kind of integral type accurate envelope noiseless two-way oiling device; Mainly solve oiling device that prior art exists and take up space greatlyyer, produce noise when crossing oil, part processing and assembling be complicacy comparatively; The oiling device hermetically-sealed construction life-span is short, technical matters such as cause that fluid leaks outside.
The utility model mainly is to solve above-mentioned technical matters through following technical proposals:
The steering jack of the utility model adopts the two-way oiling device assembly of integral type accurate envelope noiseless; Comprise body; The body endoporus has dustproof annular groove, closure gasket groove, two shoulder holes from outside to inside successively; Wherein big shoulder hole wall is evenly distributed with axial oil guide groove and communicates with interior shoulder hole, and the body cylindrical has a circular arc annular groove and a closure gasket groove.Dustproof annular groove is installed secondary lip polyurethane dust ring can prevent effectively that exterior dust, silt, water from getting into inside, has improved the resistance to abrasion and the resistance to aging of dust ring simultaneously again, has prolonged its life-span; Closure gasket groove is installed hydrogenated nitrile-butadiene rubber spiral lip seal circle, and the sealing circle has higher heat-resisting quantity, can guarantee normal operation under the higher state of oil temperature; A compound retainer is installed in big shoulder hole, because steering jack particular structural and mode of operation, piston rod can produce bigger side force when work; Especially when piston rod extended outward to end position, the side force of piston rod reached maxim, and huge side force makes piston rod and body remain linear the contact; And the on-circular uniform contact causes sealing member one side rapid wearing, and the opposite side excessive clearance; Cause leakage of oil; And the compound retainer of installation that this oiling device assembly adopts has the intensity height, coefficient of friction is little, resistance to abrasion good, can effectively keep the piston rod axial location that mediates all the time; Thereby effectively protect sealing member, prevent leakage of oil.The formed oil circuit of this oiling device assembly can guarantee that the fluid that passes in and out oil cylinder has lower negative pressure and noiseless in addition, thereby reduces waste of power and prevent that oily temperature rise is too high.Fixing between oiling device assembly and cylinder barrel through G shape ring, lean on flange face fixing different with traditional,
Locking structure is compact, installs simply, has reduced the total weight of spatial destribution and oil cylinder simultaneously.
The advantage of the utility model structure:
1, hermetically-sealed construction adopts secondary lip polyurethane dust ring and hydrogenated nitrile-butadiene rubber spiral lip seal circle combination sealing, can guarantee effectively that steering jack still has reliable sealing performance under abominable operating mode, and prolong the service life of product.
2, the compound retainer of the low abrasion factor of high strength can effectively guarantee the piston rod axial location that mediates all the time, thereby prevents contacting between piston rod and body, and uniform contact between protection sealing member and piston rod is the more important thing is in friction, prevents the eccentric wear phenomenon.
3, approximate through type larger area oil circuit can effectively reduce the negative pressure that turnover fluid produces, and prevents noise generation, reduces waste of power and prevents that oily temperature rise is too high.
4, fixed form is succinctly reliable, and is fixing through G shape ring between oiling device assembly and cylinder barrel, saved spatial destribution and the total weight that has reduced oil cylinder greatly, and this draw bail is installed, dismounting is all more convenient.
Therefore, the utlity model has good sealing effect, prolong the service life of product, noiseless, lower negative pressure, low-yield loss, simple for structure reliable, install, convenient disassembly, on car load, be prone to arrange, and can reduce characteristics such as complete vehicle quality.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is the utility model scheme of installations in steering jack;
Parts, position and numbering among the figure: body 1, secondary lip polyurethane dust ring 2, hydrogenated nitrile-butadiene rubber spiral lip seal circle 3, compound retainer 4, piston rod 5, G shape ring 6, cylinder barrel 7.
Specific embodiment
A kind of steering jack shown in accompanying drawing, comprises body 1, secondary lip polyurethane dust ring 2, hydrogenated nitrile-butadiene rubber spiral lip seal circle 3, compound retainer 4, piston rod 5, G shape ring 6, cylinder barrel 7 with the two-way oiling device assembly of integral type accurate envelope noiseless.The body endoporus has dustproof annular groove, closure gasket groove, two shoulder holes from outside to inside successively, and wherein big shoulder hole wall is evenly distributed with axial oil guide groove and communicates with interior shoulder hole, and the body cylindrical has a circular arc annular groove and a closure gasket groove.Dustproof annular groove is installed secondary lip polyurethane dust ring can prevent effectively that exterior dust, silt, water from getting into inside.Closure gasket groove is installed hydrogenated nitrile-butadiene rubber spiral lip seal circle, can guarantee normal operation under the higher state of oil temperature, and a compound retainer is installed in big shoulder hole.Fix through G shape ring between oiling device assembly and cylinder barrel, lean on flange face fixing different with traditional, locking structure is compact, installs simply, has reduced the total weight of spatial destribution and oil cylinder simultaneously.
