Problems solved by technology
[0002] Bicycles, electric bicycles and motorcycles widely use hydraulic disc brakes, which are essential components of these vehicles. Due to design, structure and manufacturing reasons, the commonly used hydraulic disc brakes are prone to the following shortcomings: First, the current hydraulic disc brakes The upper pump is easy to leak oil, the reason is that the upper pump of the open design hydraulic disc brake has two movable rubber sealing rings, these two sealing rings are constantly moving back and forth during work, and are only separated from the outside by a simple O-ring or a trumpet-shaped seal, which is prone to oil leakage
The second is that the upper pump body has an oil storage cup, and the oil storage cup has more connections with the outside world, so the sealing is difficult to guarantee
Third, it is difficult to adjust the gap between the friction plate and the disc of the open hydraulic disc brake lower pump
Fourth, the piston of the lower pump is made of steel, which is easy to conduct the heat generated by the friction plate and the disc, and is easy to damage the rubber sealing ring, and the strength of bakelite is not enough

Embodiment Construction
[0017] The present invention will be further described below in conjunction with implementation.
[0018] figure 1 Shown in is a cross-sectional view of the A-A plane of a specific embodiment of the adjustable hydraulic disc brake of the present invention, combined with figure 2 , image 3 and Figure 4 The description is as follows: when the hand grips the handle 1 tightly, the handle 1 drives the roller assembly 2, and the roller assembly 2 leans against the back of the adjusting screw 3 when it is static, and the passive roller assembly 2 pushes the adjusting screw 3 to move forward. The functional pistons 4 are threaded, so that the multi-functional piston 4 overcomes the resistance of the return spring 7 and squeezes into the cylinder tube 6, and the hydraulic oil in the cylinder tube 6 is squeezed into the lower pump body through the flexible oil tube to push the friction plate Squeeze the disc to generate braking force. When the staff relaxed, the elastic force of ...

The invention discloses an adjustable oil pressure disc brake. The adjustable oil pressure disc brake comprises an adjusting screw (3), a multifunctional piston (4), a cylinder tube (6), a rear cover (10) and an upper pump body (12), wherein the adjusting screw (3) and the multifunctional piston (4) are in threaded fit, a through hole for oil feeding and discharging is formed in the middle of the multifunctional piston (4), an internal thread is arranged at one end of the cylinder tube (6) and is in threaded fit with a connector (8), a protrusion is arranged on the rear cover (10) and matched with a pit in the upper pump body (12), the upper pump body (12) is manufactured through drawing shape extrusion of aluminum alloy, and the cylinder tube (6) is installed in a through hole in the middle of the upper pump body (12). A double-sealing ring is adopted for the upper pump body, so that sealing performance is improved; the adjustable multifunctional piston is adopted for adjusting the gap between a friction plate and a disc, so that using effect is improved; a lower pump piston is made of the glass material, so that heat resistance is improved.
