Abstract
The utility model discloses a double-piston braking master cylinder with two oil outlets on side edges and an oil compensation ring. The double-piston braking master cylinder comprises a cylinder body, wherein an oil chamber is formed in the middle of the cylinder body; a rear piston assembly is arranged at the right end of the oil chamber; a rear spring is arranged at the left end of the rear piston assembly; a front piston assembly is arranged on the left side of the rear spring; a gasket is sleeved outside the left end of the front piston assembly; a compression spring is arranged at the left end of the gasket; a spring seat is arranged at the left end of the compression spring; a front spring is arranged at the left end of the spring seat; the left end of the front spring is supported against the cylinder body; oil inlet joints are arranged on the cylinder body at the upper ends of the front piston assembly and the rear piston assembly respectively; limiting pins are arranged at the lower ends of the oil inlet joints; and an oil outlet joint is arranged on the side edge, beside each oil inlet joint, of the cylinder body. The oil outlet joints are arranged on the side edges of the cylinder body, so that the oil return efficiency can be improved effectively, a phenomenon of unsmooth oil return is avoided, and the service life of a product is prolonged.
Description
Technical field:
The utility model relates to the auto parts and components field, relates in particular to the double-piston brake master cylinder with repairing ring that a kind of side has two oil outlets.
Background technique:
Brake master cylinder band vacuum booster assembly is that power source as braking system exists basically, and it is that brake pedal force with the driver is converted into hydraulic coupling, and has certain power-assisted effect, is divided into single piston and double piston type usually; Brake master cylinder structure in the past, its delivery connection are to design in cylinder base, because the long-term hydraulic coupling that receives of using is bigger, receive the influence of liquid self gravitation simultaneously, the not smooth phenomenon of oil return often occurs.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content:
The purpose of the utility model just provides the double-piston brake master cylinder with repairing ring that a kind of side has two oil outlets; Solve brake master cylinder structure in the past; Its delivery connection is that design is in cylinder base; Because the long-term hydraulic coupling that receives of using is bigger, receives the influence of liquid self gravitation simultaneously, the technical problem of the not smooth phenomenon of oil return often occurs.
The technological scheme that the utility model adopts is:
A kind of side has the double-piston brake master cylinder with repairing ring of two oil outlets, comprises cylinder body: the cylinder body middle part has the grease chamber, and grease chamber's right-hand member is equipped with the back piston assembly; Back piston assembly left end is equipped with rear spring; The rear spring left side is equipped with the secondary piston assembly, and secondary piston assembly right-hand member is set with the secondary apron in back outward, and secondary piston assembly left end is set with repairing ring, D shape seal ring and pad outward; The pad left end is equipped with holddown spring; The holddown spring left end is equipped with spring seat, and the spring seat left end is equipped with front spring, and the front spring left end leans on cylinder body; Be respectively arranged with fuel inlet fitting on the cylinder body of secondary piston assembly and back piston assembly upper end, fuel inlet fitting and cylinder body contacting point are equipped with the oil-feed seal ring, and fuel inlet fitting is set with dust cap outward, and the fuel inlet fitting lower end is equipped with position limit pin; The other cylinder body side of each fuel inlet fitting all has delivery connection, and delivery connection is equipped with dust plug outward.
Said fuel inlet fitting and delivery connection all are connected to the grease chamber through oil duct.
Compared with prior art, the beneficial effect of the utility model is:
The utility model can effectively improve oil return efficient through delivery connection being arranged on the cylinder body side, avoids the not smooth situation of oil return that take place the working life of having improved product.
