Abstract
The utility model discloses a brake master cylinder assembly structure, comprising a cylinder body. The inner cavity of the cylinder body is provided with front and rear pistons in a sliding manner. The top of the cylinder body is provided with two oil inlets and two oil outlets. A first oil inlet is provided with an oil cup, and an oil inlet screw-plug is disposed at a joint of the oil inlet and the oil cup. A second oil inlet is also provided with an oil inlet screw-plug, and a dust shield covers the second oil inlet. The end of a rubber pipe connected to the oil cup is connected to an oil inlet joint which traverses through the dust shield and is connected to the second oil inlet. The inner upper parts of the two oil outlets are respectively provided with a cover, and the inner lower parts are respectively provided with a sealing ring. The brake master cylinder assembly structure is advantageous in that the structure is simple and easy to produce; the problem that an oil inlet is easy to be blocked by foreign matters can be effectively resolved; performance of a brake master cylinder can be greatly improved.

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 clutch, and the braking master cylinder fuel inlet mouth is prone to stopped up by foreign matter in the existing technology, causes the lubricating cup oil-feed not smooth, influences the proper functioning of brake master cylinder.
The model utility content
The utility model purpose provides a kind of brake master cylinder assy structure, is prone to blocked problem to solve existing technology clutch brake master cylinder filler opening.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of brake master cylinder assy structure comprises the cylinder body with inner chamber, and said cylinder body right-hand member has accent; It is characterized in that: be slidingly fitted with forward and backward piston in the said inner chamber of cylinder block, be connected with spring between the left end of said secondary piston and the cylinder body left end inwall, also be connected with spring between secondary piston right-hand member and the back piston left end; Said back piston right-hand member points to cylinder body right-hand member accent, and back-up ring is used in the hole that is provided with spacing back piston in the cylinder body right-hand member accent, and said cylinder body top is provided with two filler openings, two oil outlets; In two filler openings; On first filler opening lubricating cup is installed, and first filler opening and lubricating cup joint be provided with the filler opening plug screw of band cavity, also be provided with the filler opening plug screw of band cavity in second filler opening; Also be covered with dust-proof cover on second filler opening; Be connected with rubber pipe on the said lubricating cup, the fuel inlet fitting that the pipe end of said rubber pipe is connected with fuel inlet fitting and rubber pipe passes dust-proof cover and is connected on second filler opening, and two oil outlet internal upper parts are separately installed with stifle; The bottom is respectively arranged with the diameter reducing part that is connected on the cylinder body in two oil outlets, and is respectively arranged with seal ring in the diameter reducing part of oil outlet.
Described a kind of brake master cylinder assy structure is characterized in that: be with the seam seal ring near right-hand member accent position on the said cylinder body.
Described a kind of brake master cylinder assy structure is characterized in that: be provided with the filler opening packing ring between said filler opening plug screw and the lubricating cup rim of a cup place.
Described a kind of brake master cylinder assy structure is characterized in that: the filler opening plug screw in second filler opening is outside equipped with the O shape circle that constitutes sealing with second filler opening inwall.
The utility model is simple in structure; Be easy to realize; Two filler opening oil-feeds from lubricating cup respectively on the cylinder body, one of them filler opening directly is connected with lubricating cup, and the fluid in the lubricating cup gets in the cylinder body through the filler opening plug screw in the filler opening; Be connected with the fuel inlet fitting of rubber pipe pipe end on the cylinder body in another filler opening; And the dust-proof cover that fuel inlet fitting passes on this filler opening is connected with this filler opening, and the oil-feed of such two filler openings is all carried out under enclosed environment, does not have foreign matter and gets into the obstruction filler opening.The utility model can effectively solve filler opening and be prone to improved the performance of brake master cylinder greatly by the foreign matter blocking problem.
