Abstract
The invention discloses a double-cavity separation type brake master cylinder. A fixing partition plate is arranged in the middle of a cylinder body and separates the cylinder body into a driving work room and a driven work room. A driving push rod piston is arranged in the driving work room and provided with a leather cup. The driving push rod piston is connected with a connecting push rod. The connecting push rod penetrates through a partition plate oil seal and a partition plate and then is connected with a driven piston in the driven work room. A return spring can be or cannot be arranged in the driving work room. The driven work room is provided with the driven piston and a leather cup, and return spring can be or cannot be arranged in the driven work room. Compensating holes, oil inlet holes and oil outlet holes are in the cylinder body. The cross sectional area of the driving work room can be equal or unequal to the cross sectional area of the driven work room. After the double-cavity separation type brake master cylinder which is simple in structure and convenient to manufacture is adopted, complete independence of two cylinders is achieved. When braking is carried out, oil leakage of one group of leather cups of front wheels or rear wheels or a pipeline happens, the other group which is free of oil leakage can normally brake, and driving safety of automobiles is guaranteed.
Description
Technical field
The present invention relates to a kind of two-chamber separated type brake master cylinder of the braking system for motor vehicle.
Background technique
The hydraulic brake master that uses now is all to adopt single chamber brake master cylinder or two-chamber follow-up-type brake master cylinder, single chamber brake master cylinder and two-chamber follow-up-type brake master cylinder will cause not braking of automobile when running into a component cylinder leather cup in front-wheel or trailing wheel or pipeline leakage of oil when automobile brake, produce dangerous.
Summary of the invention
The purpose that the present invention relates to is for brake master cylinder and the manufacture method thereof of the good separated type of a kind of braking safety are provided.
For achieving the above object, two-chamber separated type brake master cylinder of the present invention mainly comprises cylinder body, initiatively push-rod piston is secondary, relay piston is secondary, compensate opening, oil inlet hole, oil outlet, return spring, dividing plate, oil sealing.There is stationary barrier that cylinder body is divided into first moving chamber and slave operation chamber at the middle part of cylinder body; Front end in first moving chamber has fixedly push rod oil sealing of jump ring, the push rod oil-sealing sleeve is on the pusher section of active push-rod piston, initiatively on push-rod piston, leather cup is arranged, initiatively push-rod piston with is connected the push rod connection, the connection push rod passes after dividing plate oil sealing, dividing plate with the indoor relay piston of slave operation and is connected; In first moving chamber, return spring can be arranged, also can there is no return spring, connect push rod when return spring is arranged and pass from return spring; Slave operation is indoor relay piston, leather cup, and return spring can be arranged, and also can there is no return spring; Initiatively push-rod piston and the piston group that is connected push rod, relay piston, leather cup composition and fixes, integrated moving during work; Compensate opening, oil inlet hole and the oil outlet of first moving chamber and slave operation chamber are on cylinder body; Distance between the compensate opening of the compensate opening of first moving chamber and slave operation chamber is more than or equal to the distance between the leather cup of the leather cup of first moving chamber and slave operation chamber; First moving chamber can equate with the cross-section area of slave operation chamber, also can be unequal.
In order to make front wheel brake first, the time of the leather cup sealing compensate opening that the time of two-chamber separated type brake master cylinder of the present invention leather cup sealing compensate opening in first moving chamber when work is more indoor than slave operation is Zao.
For varying in size of the required braking force of the wheel cylinder of each bridge location of coordinating automobile, the first moving chamber of two-chamber separated type brake master cylinder of the present invention can equate with the cross-section area of slave operation chamber, also can be unequal, the pressure that first moving chamber and slave operation chamber are produced when work equates or is unequal.
In order to make the minimizing discrete, the active push-rod piston of two-chamber separated type brake master cylinder of the present invention be connected push rod and can separate and be assembled into again an integral body after making, perhaps the active push-rod piston be connected push rod and manufacture an integral body; Relay piston be connected push rod and can separate and be assembled into again an integral body after making, perhaps relay piston be connected push rod and manufacture an integral body; When integral body was made, connecting push rod can not manufacture as a whole with active push-rod piston and relay piston simultaneously.
For the ease of assembling and minimizing accessory, the first moving chamber of two-chamber separated type brake master cylinder of the present invention and slave operation are indoor can return spring, also can only have in a working room return spring is arranged.
For the ease of assembling with make, the dividing plate of two-chamber separated type brake master cylinder of the present invention can separate with cylinder body and is assembled into an integral body after making again, and perhaps manufactures dividing plate and cylinder body as a whole; Cylinder body become with diaphragm manufacture as a whole after, the rear end of cylinder body is provided with the port that can seal, the relay piston that slave operation is indoor and leather cup are packed into from the back of cylinder body.
Two-chamber separated type brake master cylinder of the present invention simple in structure, be convenient to make; After having adopted two-chamber separated type brake master cylinder, realized that two-chamber is independent, when meeting wherein one group of leather cup in front-wheel or trailing wheel or pipeline leakage of oil during braking, oil tight one group can normal brake application, guaranteed the driving safety of automobile.
