Abstract
A fuel-cut cylinder of an engine structurally comprises a front end cap, a rear end cap and a cylinder barrel. A piston rod assembly, a front spring seat, an intermediate spring seat and a return spring are arranged in the cylinder barrel; a felt gas filtering pad and a retainer ring are arranged in the front end cap; a through hole is arranged on the top of the front end cap; a rectangular sealing gasket is arranged in the rear end cap; a U-shaped ring is arranged on the piston rod assembly, and a stainless steel V-shaped spring is arranged in the U-shaped ring; and the return spring is of a waist-drum-shaped structure. The polytetrafluoroethylene U-shaped ring is used as a sealing piece, requirements of the cylinder when the cylinder works under working conditions of high temperature, poor lubrication and the like can be met, the return spring of the cylinder is of the waist-drum-shaped structure, so that the problem that the wall of the cylinder barrel is scratched due to sideward bending of the spring is avoided effectively, and solid particles are prevented from entering the cylinder barrel during breathing of the cylinder by the aid of the felt gas filtering pad of the front end cap. The fuel-cut cylinder has the advantages of stable performance, reasonable design, reliability in work and long service life.
Description
Technical field
The present invention relates to a kind of heavy-duty car and stop oil gas cylinder, a kind of specifically single-acting manipulating cylinder with motor.
Background technique
At present; Heavy duty truck, large and medium-sized passenger vehicle adopt mostly and stop oil gas cylinder cut-out oil circuit; This product is installed and used near motor, and operating temperature is higher, and conventional products sealing material selection in the market and product structure are difficult to satisfy the worst hot case demand; Mainly show: 1, lubricating grease non-refractory, solidify the wearing and tearing that Sealing is accelerated in the back; 2, spring stability is not enough, when stopping oil gas cylinder work, and the spring lateral bending; The cylinder barrel wall is pulled in scraping, finally causes cylinder seal to lose efficacy, and has reduced the working life that stops oil gas cylinder; In recent years, also have and much stop the oil gas cylinder manufacturer and done architecture advances, but using effect was all undesirable.
Summary of the invention
The object of the present invention is to provide a kind of motor to stop oil gas cylinder, this stops oil gas cylinder and can effectively slow down the wearing and tearing of cylinder seal spare and prevent spring to the pulling of casing wall, thereby increases substantially the working life that stops oil gas cylinder.
The present invention solves the technological scheme that its technical problem takes: a kind of motor stops oil gas cylinder, comprises front cover, rear end cover and connects the cylinder barrel of front cover and rear end cover, is provided with piston rod assembly, front spring seat, middle springs seat and return spring in the cylinder barrel; Be provided with felt filter air cushion, back-up ring in the described front cover, the front cover top is provided with through hole; Be provided with the rectangular seal pad in the described rear end cover; U type circle is housed on the described piston rod assembly, in the described U type circle stainless steel V-type spring is housed; Described return spring adopts dolioform structure, and the section of return spring forms the camber line that concaves.
Described U type circle adopts teflon to process.
Compared with prior art, the present invention has following beneficial effect: cylinder adopts teflon U type circle as Sealing, can satisfy the needs of operating modes such as cylinder high temperature, insufficient lubrication; The cylinder return spring adopts dolioform structure, and its section forms the camber line that concaves, and has effectively avoided the scuffing of spring bending to the cylinder barrel wall; The use of front cover felt filter air cushion, solid particle gets into cylinder barrel when having avoided cylinder to breathe.Has stable performance, reasonable in design, reliable operation, the characteristics of long service life.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present invention;
Fig. 2 is the structure for amplifying schematic representation of piston rod assembly hermetic unit of the present invention.
Among the figure: 1 piston rod assembly, 2 through holes, 3 felts filter air cushion, 4 back-up rings, 5 front covers, 6 front spring seats, 7 middle springs seats, 8 return springs, 9 cylinder barrels, 10 rectangular seal pads, 11 rear end covers, 12U type circle, 13 stainless steel V-type springs.
Embodiment
Below in conjunction with Figure of description 1 and accompanying drawing 2 and embodiment the present invention is done further description:
A kind of motor stops oil gas cylinder, comprises the cylinder barrel 9 of front cover 5, rear end cover 11 and connection front cover 5 and rear end cover 11, is provided with piston rod assembly 1, front spring seat 6, middle springs seat 7 and return spring 8 in the cylinder barrel 9; Be provided with felt filter air cushion 3, back-up ring 4 in the described front cover 5, front cover 5 tops are provided with through hole 2; Be provided with rectangular seal pad 10 in the described rear end cover 11; U type circle 12 is housed on the described piston rod assembly 1, in the described U type circle 12 stainless steel V-type spring 13 is housed; Described return spring 8 adopts dolioform structure, and the section of return spring 8 forms the camber line that concaves.
Described U type circle 12 adopts teflon to process.
Cylinder adopts teflon U type circle 12 as Sealing among the present invention, can satisfy the needs of operating modes such as cylinder high temperature, insufficient lubrication, and stainless steel V-type spring 13 is housed in the U type circle 12; Suitable spring force adds system fluid pressure; Its seal operation lip is ejected and pushes down gently the face that is sealed, to produce very excellent sealing effect, the characteristic of profit certainly that polytetrafluoroethylmaterial material is given prominence to; Reduce friction, thereby prolonged the working life that stops oil gas cylinder.Cylinder return spring 8 adopts dolioform structure, and its section forms the camber line that concaves, and has effectively avoided the scuffing of return spring 8 lateral bendings to cylinder barrel 9 inwalls.The use of front cover 5 internal hair felt filter air cushions 3, solid particle gets into cylinder barrel 9 when having avoided cylinder to breathe, and has effectively avoided the wearing and tearing of inner wall of cylinder and Sealing, has improved the working life of cylinder.
The above; Principles more of the present invention just explain through diagrams; This specification be not be to the present invention be confined to shown in described concrete structure and the Applicable scope; So every the modify and equivalent that might be utilized, claim, particularly heavy-duty car differential lock cylinder that all belongs to the present invention and applied for and the manipulating cylinder in the engine exhaust complemental brake system.
Except that the said technical characteristics of specification, all the other technical characteristicss are those skilled in the art's known technology.
