設於煞車總泵之主油缸内的活塞前進運動，將主油缸内的液 壓油推入煞車卡甜之副油缸，使副油缸處的煞車片朝向煞車 碟盤方向前進，利用煞車片與輪轂上的煞車碟盤接觸，進而 對車輪產生摯動作用。 以及，當騎士鬆開煞車手把時，主油缸内的活塞或副油 缸處的煞車片可在彈簧之作用下後退，並使煞車手把回復到 鲁預定的角度。再者，經過幾次煞車動作之後，煞車片難免會 產生磨損（變薄），因此必須相對增加活塞的往復行程，方得

Description of the Invention: [Technical Field of the Invention] The present invention relates to a hydraulic brake device, and aims to provide a brake master cylinder structure which is convenient to assemble and which can provide a better sealing effect on hydraulic oil. [Prior Art] Press, the hydraulic brake device used by locomotives or bicycles should be regarded as one of the most commonly used hydraulic devices. It is mainly equipped with a brake pump, a handlebar-driven brake master cylinder, and a hydraulic pipe. The road is connected to the brake caliper which is opposite to the wheel; when the knight presses the handlebar, the handle moves the piston forward relative to the piston provided in the main cylinder of the brake master cylinder to push the hydraulic oil in the master cylinder into the brake The sub-cylinder of the card sweetness advances the brake piece at the sub-cylinder toward the brake disc, and contacts the brake disc on the hub by the brake disc, thereby causing a smashing action on the wheel. And, when the rider releases the handlebars, the brakes at the piston or sub-cylinder in the master cylinder can be retracted under the action of the spring and return the rider to a predetermined angle. Moreover, after several braking operations, the brake shoes will inevitably wear out (thinning), so the reciprocating stroke of the piston must be relatively increased to achieve the desired braking effect. In order to avoid the above factors, the driver cannot completely reset. It even affects the braking force; in general, the main pump of the brake is equipped with an oil can (or oil cup), and an oil hole is connected to the oil pot at the reciprocating stroke of the piston of the main cylinder. In order to completely retreat the piston, the hydraulic oil in the oil can be automatically filled with hydraulic oil to the hydraulic circuit at the front end of the piston via the oil return hole, so that the brake driver is returned to the predetermined position because the brake shoe is worn out. Angle, and 201219250 maintain the proper braking effect. However, the 'traditional brake master cylinders are equipped with oil tanks at the radial position of the handlebars relative to the main cylinders. It must be provided with a leak-stop structure at the oil kettle and the connecting passage between the piston and the brake handlebars respectively. In order to prevent leakage of hydraulic oil, this not only affects the aesthetics of the overall brake master cylinder, but also increases the assembly difficulty of the overall brake master cylinder. In particular, the sealing effect of the overall hydraulic oil is relatively insufficient. Therefore, the brake master cylinder applied to the locomotive or bicycle, whether or not it has the function of automatically filling the hydraulic oil, can positively improve the assembly convenience of the brake master cylinder and increase the sealing effect on the hydraulic oil. The reliability of the brake master cylinder. SUMMARY OF THE INVENTION In view of the above, the present invention provides a brake master cylinder structure which is easy to assemble and which has a better sealing effect on hydraulic oil, and is mainly used for its main purpose.
