Abstract
The invention discloses a brake master cylinder, which comprises a cylinder body, wherein a rear piston is arranged in the cylinder body in a sliding way; a guide sleeve is arranged in a cavity opening at the left end of the cylinder body; a front piston connected with the rear piston into a whole is arranged in the guide sleeve in a sliding way; an oil inlet seal ring and a seal ring are arranged in oil inlets on the top of the cylinder body; and a limit screw extending into the cylinder body to limit the rear piston is arranged in a limit opening at the bottom of the cylinder body. The brake master cylinder has a simple structure, is easy to implement, and can effectively improve the performance of pistons in the brake master cylinder to further improve the braking performance of a clutch.
Description
Technical field
The present invention relates to clutch field, be 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.
Summary of the invention
The object of the invention 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 present invention 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 present invention 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 present invention can effectively improve the performance of piston in the brake master cylinder, and then improves the braking of clutch.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Brake master cylinder as shown in Figure 1 comprises cylinder body 1, and cylinder body 1 left end has accent; Be slidingly fitted with back piston 3 in the cylinder body 1, be connected with spring between back piston 3 right-hand members and the cylinder body 1 right-hand member sidewall, be provided with guide sleeve 2 in the cylinder body 1 left end accent; Be slidingly fitted with in the guide sleeve 2 and stretch into the secondary piston 4 that connects as one with back piston 3 in the cylinder body 1; And also be connected with spring between secondary piston 4 right-hand members and back piston 3 left ends, cylinder body 1 top also is provided with two filler openings, is respectively arranged with filler opening seal ring 6 in the filler opening; Cylinder body 1 bottom has position-limitting mouth, is provided with the stop screw 9 that stretches into cylinder body 1 spacing back piston 3 in the position-limitting mouth.
Two filler opening top together support have retainer 5, are rotatablely equipped with bearing pin 8 in the retainer 5.
The hole that is provided with spacing guide sleeve 2 in the cylinder body 1 left end accent is with back-up ring 11.
