Description
Technical field
The utility model relates to clutch field, is specially a kind of brake master cylinder assy.
Background technique
Clutch is installed between motor and the speed changer, be in the automotive transmission directly and total member of interrelating of motor.Usually clutch is installed together with the engine crankshaft flywheel set, is the parts of cut-out and transferring power between motor and the automotive transmission.Brake master cylinder is a vitals of clutch, and the structural behaviour of brake master cylinder directly has influence on the working efficiency of break, in the existing technology brake master cylinder be prone to that sealing is poor, oil circuit flow untimely, and the piston motion problem that can't in time reset.
The model utility content
The utility model purpose provides a kind of brake master cylinder assy, to solve the problem that existing technology clutch brake master cylinder piston can't in time reset.
In order to achieve the above object, the technological scheme that the utility model adopted is:
Brake master cylinder assy comprises cylinder body, and the cylinder body left end has accent; It is characterized in that: cylinder body left end place is connected with dust-proof cover, and left part is slidingly fitted with secondary piston in the cylinder body, and right part is slidingly fitted with the back piston that connects as one with secondary piston in the cylinder body; Between back piston right-hand member and the cylinder body right-hand member sidewall, be connected with spring respectively between back piston left end and the secondary piston right-hand member; The cylinder body top is provided with a pair of filler opening, and filler opening forms stepped part outward respectively, is separately installed with on the filler opening through clip and is stuck in the fuel inlet fitting on the filler opening stepped part; The cylinder body top also is provided with a pair of oil outlet; Be separately installed with delivery connection in the oil outlet, the delivery connection bottom is connected with the one-way valve oil sealing respectively in each oil outlet, and is connected with spring respectively between each one-way valve oil sealing and each the self-corresponding cylinder body; Cylinder base has position-limitting mouth, is provided with the stop screw that stretches into the spacing back piston of cylinder body in the position-limitting mouth.
Described brake master cylinder assy is characterized in that: the port of fuel inlet fitting is covered with stifle, and fuel inlet fitting and filler opening contacting point are provided with the oil-feed seal ring.
Described brake master cylinder assy is characterized in that: the delivery connection top is provided with stifle, and delivery connection and oil outlet contacting point are provided with pad.
Described brake master cylinder assy is characterized in that: stop screw is with the packing ring that is arranged between position-limitting mouth and the stop screw nut outward.
Described brake master cylinder assy is characterized in that: back-up ring is used in the hole that is provided with spacing secondary piston in the cylinder body left end accent.
The utility model is simple in structure, is easy to realize, has in the cylinder body to connect the forward and backward piston that cooperates; The cylinder body top is provided with filler opening; Filler opening seals through the oil-feed seal ring between filler opening and the fuel inlet fitting through the fuel inlet fitting oil-feed, to improve the cylinder body sealing.The sealing when one-way valve of delivery connection bottom sealing also raising master cylinder is fuel-displaced in the oil outlet.Cylinder base is provided with position-limitting mouth, and the stop screw that stretches into the spacing back piston motion of cylinder body is installed in the position-limitting mouth, can in time change the motion state of back piston, thereby realizes resetting of back piston.The utility model can effectively improve the performance of piston in the brake master cylinder, and then improves the braking of clutch.
