Mountain bike brake pad grinding device

Abstract

The invention discloses a mountain bike brake pad grinding device. After a brake pad stained with oil is disassembled from a mountain bike, the brake pad is immersed in an alcohol solution for cleaning, after cleaning is completed, the brake pad is fixed to a corresponding sliding plate by screws, a motor rotates and drives a rotating shaft to rotate by a differential mechanism so as to enable a rotating wheel to rotate, since the outer side end surface of a sand bar is located on the outer side of the rotating wheel, under the action of a spring, the sliding plate is driven to slide outwardsalong a guide rod to enable the brake surface of the brake pad to be in contact with the sand bar on the rotating wheel which rotates, so that the grinding of the outer surface of the brake pad is realized, after the part, immersed in the oil, of the brake pad is ground away, the braking friction force of the brake pad is restored, the rotation resistance of the rotating wheel increases after thefriction force of the brake pad is restored, at the time, the rotation speed of the rotating wheel has a downward trend, so the output end of the differential mechanism slips relative to the input end, the motor is protected, the convenience of repairing the brake pad which is stained with oil is improved, and the using cost of the mountain bike is saved.

Description

technical field [0001] The invention relates to the technical field of maintenance tools for mountain bikes, in particular to a grinding device for reams of mountain bikes. Background technique [0002] As urban traffic becomes more and more congested, more and more people choose bicycles as a means of travel again. Cycling is not only green and environmentally friendly, but also exercise. Compared with road bicycles, mountain bikes are the most commonly chosen bicycle type because of their wide tires, strong and durable workshops, front shock absorption, and upright riding posture. The system is divided into V brakes and disc brakes. V brakes are used in low-end mountain bikes. Now more and more mid-to-high-end mountain bikes generally use disc brakes, because disc brakes are made of metal fixed on the wheels. The disc is braked by friction with the oil pressure or on the cable clamp, so its braking force is strong, the safety factor is high, and it is not affected by rain...

AI Technical Summary

Problems solved by technology

[0003] However, due to the existence of the transmission system of the mountain bike, the chain is exposed, and the chain needs to be regularly lubricated with chain lubricating oil to lubricate the transmission system, otherwise it will cause the situation that the transmission is not smooth due to lack of lubricating oil

When lubricating oil is added to the tower wheel attachment of the rear wheel, the lubricating oil is easy to splash on the pad, once the pad is stained with lubricating oil, the braking force will be greatly reduced, and there will be a howling sound when braking

It would be wasteful to directly replace the pad with a new one. The traditional method is to soak the pad in alcohol after dismantling it in the future. After soaking, the outer surface of the pad is manually polished with fine sandpaper. force, it is also easy to cause the phenomenon of eccentric wear
