Description

Disc brake of electric bicycle

Technical Field

The utility model relates to the technical field of bicycle disc brakes, in particular to an electric bicycle disc brake.

Background

When the disc brake is composed of a brake disc connected with a wheel and a brake caliper at the edge of the disc, high-pressure brake oil pushes a brake block to clamp the brake disc, so that the braking effect is generated. Disc brakes are sometimes called disc brakes, which are classified into general disc brakes and ventilated disc brakes. The ventilated disc brake is characterized in that a plurality of circular ventilation holes are drilled on the disc surface, or ventilation grooves are cut on the end surface of the disc or rectangular ventilation holes are prefabricated. The cold and hot effect of the ventilation disc brake is better than that of the common disc brake by utilizing the action of wind flow. The main advantages of disc brake are that it can brake quickly when braking at high speed, its heat-radiating effect is superior to that of drum brake, and its brake efficiency is good, and two sides of brake disc are equipped with a flat brake shoe, when the oil pressure from brake master pump is fed into cylinder, the brake shoe can be clamped toward brake disc so as to attain the effect of tightly braking.

The existing disc brake adopts a single piston, so that the stability of the device is poor, and the braking effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an electric bicycle disc brake to solve the problems in the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an electric bicycle dish is stopped, includes little main part of piston and the big main part of piston, be provided with the spring leaf between little main part of piston and the big main part of piston, be provided with main part sealing washer, main part piston and brake block between spring leaf and the little main part of piston, be provided with main part sealing washer, main part piston and brake block between spring leaf and the big main part of piston, the side-mounting of the little main part of piston has oil pipe.

Preferably, the small piston body and the large piston body are fixed through fastening screws through mechanical energy, and a caliper plug pin is further arranged between the small piston body and the large piston body.

Preferably, calliper oil filler point screw is installed to oil pipe one end, oil pipe passes through calliper oil filler point screw and installs on the little main part of piston.

Compared with the prior art, the utility model has the beneficial effects that: oil pressure pushes the piston to move forward and the rear leg, so that the brake disc is clamped by the brake pad to brake and loosen to achieve the purpose of braking, the two main pistons are arranged, and the stability of the double pistons is high.
