Abstract
The utility model discloses a brake master cylinder which comprises a cylinder block. A rear piston is slidably mounted in the cylinder block. A guide bush is disposed in a left cavity opening of the cylinder block, and a front piston integrally connected with the rear piston is slidably mounted in the guide bush. Oil inlet seal rings are disposed in oil inlets reserved at the top of the cylinder block respectively. A limit screw extending into the cylinder block to limit the rear piston is disposed in a limit hole reserved at the bottom of the cylinder block. The brake master cylinder is simple in structure and easy to implement, and by the aid of the brake master cylinder, performance of the pistons in the master brake cylinder can be improved effectively and braking performance of a clutch is improved.
Description
Technical field
The utility model relates to clutch field, is specially a kind of brake master cylinder.
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, and brake master cylinder is prone to poor, the easy oil leakage of sealing in the existing technology, 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, to solve the problem that piston can't in time reset in the existing technology clutch brake master cylinder.
In order to achieve the above object, the technological scheme that the utility model adopted is:
Brake master cylinder comprises cylinder body, and the cylinder body left end has accent; It is characterized in that: be slidingly fitted with back piston in the cylinder body, be connected with spring between back piston right-hand member and the cylinder body right-hand member sidewall, be provided with guide sleeve in the cylinder body left end accent; Be slidingly fitted with in the guide sleeve and stretch into the secondary piston that connects as one with back piston in the cylinder body; And also be connected with spring between secondary piston right-hand member and the back piston left end, the cylinder body top also is provided with two filler openings, is respectively arranged with the filler opening seal ring in the filler opening; 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 is characterized in that: two filler opening top together support have retainer, are rotatablely equipped with bearing pin in the retainer.
Described brake master cylinder is characterized in that: back-up ring is used in the hole that is provided with spacing guide sleeve in the cylinder body left end accent.
Described brake master cylinder 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 is characterized in that: cylinder body also is provided with O shape circle outward.
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, and the cylinder body top is provided with filler opening, and filler opening is through the seal ring sealing, to improve the cylinder body sealing.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.
