Hydraulic disc brake with valve
A hydraulic disc brake and valve technology applied to hydraulic disc brakes. It can solve the problems of reducing the total oil volume, reducing the height of the upper pump body, and reducing the steps of refueling and oil changing, so as to reduce oil leakage, reduce the trouble of use and maintenance, and save materials and brake oil.

Embodiment Construction
[0018] The present invention will be further explained below in conjunction with implementation.
[0019] figure 1 Shown in is a three-dimensional exploded view of a specific embodiment of a hydraulic disc brake with a valve of the present invention, which is described with reference to Figures 2 and 3 as follows: When a human hand grips the handle 3, the handle 3 drives the round head pillar 10 to press down Once the upper pump piston 8 and the upper pump piston 8 move and overcome the resistance of the upper pump spring 9, it pushes the valve core 6 to move to the outside, closing the oil path leading to the oil storage cup 1.1, and then the entire oil path is closed. In the oil circuit, when the human hand continues to hold the handle 3, the pressure is transmitted to the lower pump body through the oil pipe. The lower pump body consists of a large pump body 20, a small pump body 21, a connecting screw 17, an outer sealing ring 18, an inner sealing ring 19 and Other publicly-u...

The invention discloses an oil pressure disk brake with a valve. A circular-ring slot for arranging an upper pump sealing ring (15) and a hole for mounting a valve core (6) are formed in an oil cylinder of an upper pump body (1); an upper pump piston (8) is a cylinder; the valve core (6) keeps an oil path often opened; when the upper pump piston (8) moves, pressure is generated on the valve core (6) so as to close an oil path valve; a handle seat (2) and a handle (3) are detachably connected, and an angle of the handle (3) can be adjusted; an oil discharging column (16) occupies the volume, so that the oil amount is reduced; each cylinder of a large pump body (20) and a small pump body (21) is provided with two holes which are in mirror image symmetric arrangement; a passageway through which braking oil flows is formed in a clearance among a communicating screw (17), the large pump body (20) and the small pump body (21). According to the oil pressure disk brake with the valve, the possibility of oil leakage of the oil pressure disk brake is reduced, materials are saved, and the trouble of customer maintenance is reduced.
Description
Technical field [0001] The invention relates to hydraulic disc brakes used in bicycles, electric bicycles and motorcycles, referred to as hydraulic disc brakes. Background technique [0002] Bicycles, electric bicycles and motorcycles widely use hydraulic disc brakes, which are essential components for these vehicles. The currently commonly used hydraulic disc brakes are prone to the following shortcomings due to the design structure and manufacturing reasons: First, the current hydraulic disc brakes The upper pump is prone to oil leakage. The reason is that the upper pump of the open design hydraulic disc brake has two movable rubber sealing rings. These two sealing rings keep moving back and forth during operation, wear and deform under force, and are easily damaged; There is only a simple 0-shaped sealing ring or a horn-shaped sealing ring between the oil circuit and the outside, which is easy to leak oil. Secondly, the compressed length of the coil spring in the cylinder of ...
