If adjustment is required, the double-piston braking main cylinder can be adjusted only by operating from the upper end of the cylinder body, the cylinder body does not need to be dismounted wholly, and the operation is convenient.
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 filler opening is provided with position limit pin.
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.
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 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 utility model 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, the beneficial effect of the utility model is:
The utility model has been 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.
