Abstract
The utility model discloses sealing-type design of a clutch booster. Novel engineering materials are applied to a piston. A piston rod sealing mode is adopted by a control valve of the clutch booster, namely, a seal ring is installed on a valve body, and in the working process, movable sealing is conducted on an inner ring of the seal ring; the materials of a valve rod are polyphenylene sulfide (PPS); a guide sleeve made of the PPS is installed on the valve body; the valve rod does not make contact with the aluminum alloy valve body; and the piston of a cylinder and the piston rod are of an integral structure, and are once formed by PPS injection. The clutch booster optimizes a sealing mode, utilizes the characteristics of low frictional coefficient, high strength and corrosion resistance of the PPS materials and is suitable for an automobile clutch booster. Compared with the prior art, the clutch booster has the advantages of being reasonable in structure, long in service life, high in strength, corrosion-resistant and the like.
Description
Technical field
The utility model relates to a kind of automobile component of automobile manufacturing field, and specifically, the utility model is a kind of seal form and new material utilization of automobile-used clutch booster.
Background technique
Because of full-sized car power big, load is heavy, so the torque force of clutch transmits is big, the pressure of respective pinch mechanism is also big, handle light and minimizing driving intensity for making, the clutch operation of full-sized car is equipped with hydraulic control air pressure booster type booster, its effect is that release bearing is separated easily, operating mechanism is submissive steadily laborsaving, traditional clutch booster control piston bar partly adopts the piston seal form, be that seal ring is installed on the control valve rod, seal ring slides on the valve body hole wall in the working procedure, control simultaneously that valve rod is relative with hole wall to rub, the wear metal surface is destroyed friction pair and is polluted brake fluid easily, make the clutch booster gas leak of the oil leakage, cause early failue.Traditional oil cylinder piston bar is to finish grind behind the steel surface hard chromium plating to form, and itself requires high surface finishment and hardness.In working procedure repeatedly, piston rod and guide ring friction cause piston rod surface wearing and tearing back leakage of oil easily.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, provides a kind of seal form reliable, long-lived clutch booster.
The purpose of the present utility model is achieved through the following technical solutions:
A kind of clutch booster, comprise valve body, two way sealed circle, guide sleeve, O type circle, control valve rod, seal ring, thrust fitting, piston rod, setting sleeve and oil sealing, in the control valve part, do not adorn seal ring on the control valve rod, adopt the rod seal form, on the control valve rod guide sleeve is housed, the direct and valve body formation friction pair of control valve rod, the two way sealed circle is equipped with in the step hole lower end of valve body, guide sleeve is equipped with in the upper end, and O type circle is housed in the hole, and the control valve rod is in the centre, seal ring seal control valve bar brake fluid, O type circle seal control valve bar pressurized air; Guide sleeve and control valve rod for improving working life, are installed the guide sleeve that polyphenylene sulfide (PPS) is made simultaneously by new engineering material polyphenylene sulfide (PPS) molding and forming on valve body, avoid and the relative friction of metal generation; Like this, both improve dexterity of action, prolonged the working life of seal ring again; Cylinder piston and oil cylinder piston bar are overall structure, once injection moulding, cylinder piston and oil cylinder piston bar are whole to be made up of the molding and forming of new engineering material polyphenylene thioether PPS, because this material behavior, do not need guide ring on the cylinder piston, disposable moulding has also guaranteed the concentricity of cylinder piston and oil cylinder piston bar; The low coefficient of friction characteristic of piston rod has prolonged working life of oil sealing.
Compared with prior art, the utlity model has following beneficial effect:
1. rational in infrastructure, long service life;
2. has the high-strength corrosion-resisting characteristic.
