Among them: X months to 1_ because the hydraulic master cylinder is operating the material, the hydraulic oil will produce the phase of the seat to drive the brake calipers and other components, if the casting method: This month, the ugly will be easy because the manufacturing process remains The internal seam of the structure causes structural damage or hydraulic pressure on the brake body. (4) Q. The existing brake body must be made in a forged manner. The second guide only causes the addition and non-formation of the brake body to be laborious and time consuming. Manufacturing cost 3 M362817 South 0 2. The existing hydraulic master cylinder structure generally requires the piston assembly and internal components to be placed in the relevant position of the brake body in sequence, and locked and fixed one by one, in order to complete the assembly of the hydraulic master cylinder. The installation work is not only complicated in the assembly structure of each component, but also the assembly process is too inconvenient and inconvenient. [New content] In order to solve the problems and limitations of the hydraulic master cylinder of the existing bicycle, such as complicated structure, troublesome assembly, and manufacturing cost, the present invention provides a hydraulic master cylinder for assembling a bicycle that is easy to use and has good structural strength. This creation mainly installs a piston cylinder inside the cylinder groove of the body, so that the piston assembly can be pre-assembled inside the piston cylinder, which simplifies the assembly work of the hydraulic master cylinder, and the piston cylinder can make the body not directly bear the piston assembly driving process. The high pressure effect effectively reduces the requirements of the forming method and material of the body, and achieves the progressive effect of reducing the manufacturing cost of the hydraulic master cylinder. The technical means used in the present invention is to provide a hydraulic master cylinder for a bicycle, comprising: a body having a cylinder groove therein, the cylinder groove being provided with a closed end and an end end in the cylinder groove a screw cap is disposed in the open end, and the screw cap is provided with a rod hole. The body is provided with a hydraulic pressure close to a closed end of the cylinder, and an oil storage cup is provided in the body. The oil cup flow path is connected to the middle portion of the arranging tank; the piston cylinder is a hollow cylindrical cylinder body and is provided with an open end and is closed and embedded in the closed end inwardly. The tank is grooved - the worm's 'τ' benefits the 疋 ' 't hollow cylinder to form a cylinder chamber, 4 M362817 square; the outer circumference of the piston cylinder is surrounded by a ring & ring The cylinder wall of the tongue plug cylinder and the cylinder wall near the closed end are provided with a hydraulic hole that can communicate with the hydraulic flow passage, and a guide hole and a pilot hole are respectively arranged in the cylinder wall between the two convex rings. And the bow bore system is in communication with the oil cup flow passage; and - the active base set 'The system is located in the cylinder chamber and includes a return spring that abuts against the closed end of the red chamber, a piston that abuts the return spring, and a - abuts against the piston and is pierced by the rod hole provided by the screw cap Putt. The body of the 'cylinder master cylinder' is provided with a handle at one end of the screw cap. The handle base is coupled with a swingable operating handle, and the push rod is coupled to the operating handle. In the foregoing hydraulic main red, the cylinder groove is divided into an inner groove section and an outer groove section having an inner diameter slightly larger than the inner groove section and 2 steps from the inner and outer groove sections; The convex ring on the side of the closed end of the red body is closely abutted against the stepped surface through a sealing ring, and the molybdenum is unloaded and the convex ring facing the open end side is closely abutted against the screw cap through a sealing ring. Inner end face. The liquid inviting master cylinder described in k#, wherein the main body is provided with a center cup and a replenishing hole in the middle portion, the oil replenishing hole is connected to the middle portion of the cylinder trough by the replenishing oil passage, and is supplemented Oil hole Λ, A 3, by screw, in the oil storage cup, '. The S is provided with a detachable oil cup cover, and the + 卫 4 oil cup 盍 and the oil storage cup 4 are provided with a resilient spacer. • The above-mentioned hydraulic master cylinder, the opening direction of the oil reservoir and the oil filling hole of the complex φ 沾 、, 山 _ _ /, is roughly the same direction and is located on the top side of the body. The master cylinder, the power enhancement includes: The piston assembly can be pre-mounted in the cylindrical piston cylinder 5 M362817 in order to obtain the advantages of the child, and the piston cylinder can be directly placed into the cylinder groove of the body, and the screw can be used. The lock fixing position 1 easily completes the assembly of the internal components of the hydraulic master cylinder (4), which effectively makes the assembly of the hydraulic master cylinder easier and easier. ', "The second creation of the body is equipped with a piston cylinder, which can be used to convert the internal part of the body into a high-pressure zone that directly bears the action of the piston assembly, and is located outside the piston cylinder. The low-pressure zone of the scoop is used to make the body only pressurize. Simple and low (four) processing and way to form 'effectively achieves the efficiency of simplifying the reinforcement and reducing costs.' 3. The oil storage cup of this creation is connected to the outer part of the piston red through a oil cup flow path, and will be elastic The spacer is assembled in the opening position of the oil cup, which effectively simplifies the structure and facilitates the installation. 4. The present invention sets the oil cup cover and the oil filling screw on the upward side of the hydraulic cylinder body and is located substantially the same. In the disassembly direction, the oil replenishing operation of the hydraulic oil can be directly performed without removing the oil sump cover, and the convenience of the replenishing operation can be improved. [Embodiment] In order to understand the technical features and practical effects of the creation in detail, In accordance with the contents of the specification, it is further described in detail with the preferred embodiment shown in the following figure: The hydraulic master cylinder of the bicycle provided by the present invention can be applied to the self.
