Description

Technical Field

[0001] This utility model relates to the field of braking system technology, and in particular to a cable-operated hydraulic disc placed under the handlebar cross tube. Background Technology

[0002] Cable-operated hydraulic disc brakes are a type of bicycle braking system that combines the advantages of cable-operated disc brakes and hydraulic disc brakes. It uses the tension of the brake cable to cause the brake pads inside the caliper to rub against and clamp the disc, while simultaneously utilizing a hydraulic system to enhance braking performance and reduce the risk of leaks.

First, the braking effect of current cable-operated hydraulic disc brakes is not ideal, and there is a risk of oil leakage. Second, the current cable-operated hydraulic disc brakes have a complex structure and high subsequent maintenance costs. Therefore, a cable-operated hydraulic disc brake placed under the handlebar tube is needed to solve the above problems. Utility Model Content

The function of the left and right oil reservoirs 1e1 and 1e2 is to compensate for brake pad wear by storing oil within them. Simultaneously, air in the hydraulic system can be vented into the oil reservoir assembly 1e, thus not affecting braking performance. The oil reservoir assembly 1e is secured by an oil reservoir 22 pressed down by an anti-rotation washer 21, which in turn is secured by an oil reservoir locking nut 20. The oil reservoir locking nut 20 is connected to the upper pump 1 via threads and is fixed in place by a set screw 9 to prevent loosening. The upper pump 1 has two master pump front oil holes 1h and a master pump rear oil hole 1i. The master cylinder front oil port 1h is used to replenish the brake system with oil from the reservoir assembly 1e after the brake pads wear. Simultaneously, air in the brake system can also be expelled into the reservoir assembly 1e through this port. The master cylinder rear oil port 1i serves to lubricate the rear O-ring seal 23. The oil filling holes of the reservoir assembly 1e are sealed by the grease fitting screw 24 by pressing the O-ring seal 23.
