Abstract
The invention discloses a double-piston brake master cylinder with an oil supplementing ring and limit pins at oil inlets. The double-piston brake master cylinder comprises a cylinder body, an oil chamber is arranged in the middle of the cylinder body, a rear piston assembly is mounted at the rear end of the oil chamber, a gasket is sleeved on the outer wall of the left end of the rear piston assembly, a pressure spring is mounted at the left end of the gasket, a spring seat is mounted at the left end of the pressure spring, a rear spring is mounted at the left end of the spring seat, a front piston assembly is mounted on the left of the rear spring, a front spring is mounted at the left end of the front piston assembly, a screw cap is mounted at the left end of the cylinder body, the left end of the front spring is abutted to the screw cap, oil inlet joints are arranged at the upper ends of the front piston assembly and the rear piston assembly on the cylinder body respectively, the limit pins are mounted at the lower ends of the oil inlet joints, and an oil outlet joint is arranged beside each oil inlet joint and at the upper end of the cylinder body. As the limit pins are mounted at the lower ends of the oil inlet joints, limit screws at the lower end of the cylinder body are omitted, if needing adjustment, the double-piston brake master cylinder can be adjusted only from the upper end of the cylinder body without integrally detaching the cylinder body, and operation is facilitated.
Description
Technical field:
The present invention relates to the auto parts and components field, relate in particular to the double-piston brake master cylinder that a kind of filler opening is provided with position limit pin with repairing ring.
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 is in cylinder base the distance that caging bolt comes limited piston to move to be installed mostly, because bolt is arranged on cylinder base, replacing or adjustment are all more bothersome, need disassemble whole cylinder body usually and just be convenient to operation.Therefore imagination provides a kind of equipment to solve this problem.
Summary of the invention:
The object of the invention just provides the double-piston brake master cylinder with repairing ring that a kind of filler opening is provided with position limit pin; Solve brake master cylinder structure in the past; Be the distance that caging bolt comes limited piston to move to be installed mostly in cylinder base; Because bolt is arranged on cylinder base, change or adjustment all more bothersome, need disassemble whole cylinder body usually and just be convenient to the technical problem of operating.
The technological scheme that the present invention adopts is:
A kind of filler opening is provided with the double-piston brake master cylinder with repairing ring of position limit pin, 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; Be set with secondary apron on the back piston assembly right-hand member outer wall, be set with repairing ring, D shape seal ring and pad on the back piston assembly left end outer wall, 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 rear spring, and the rear spring left side is equipped with the secondary piston assembly; Secondary piston assembly left end is equipped with front spring; The cylinder body left end is equipped with blind nut, between blind nut and the cylinder body copper backing is installed, and the front spring left end leans on blind nut; 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 upper end 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, beneficial effect of the present invention is:
The present invention has cancelled the stop screw of cylinder body lower end through position limit pin is installed in the fuel inlet fitting lower end, only need get final product from the operation of cylinder body upper end like the need adjustment, need not cylinder body integral body to be pulled down easy-to-operat.
