Bicycle using air brake

Abstract

The invention discloses a bicycle using an air brake. The bicycle is characterized by comprising a frame, wherein the frame is provided with a handle, a front wheel, a rear wheel, a mounting rod and aseat, axles are arranged on the front wheel and the rear wheel, one sides of the axles are connected to a brake assembly, the brake assembly comprises a brake part fixedly connected to the axles, a ring-shaped brake groove is formed in the brake part, one end, near a fixed bracket, of the brake groove is fixedly connected to an elastic rubber, the elastic rubber is in sealed connection with a brake block groove, the elastic rubber is fixedly connected to a plurality of brake blocks, a communication pipe is arranged on the wall surface of the brake groove, the brake assembly also comprises thefixed bracket fixed to the wheels, the fixed bracket rotates around and is in sealed connection with the brake part, the brake block groove is formed in the fixed bracket, a piston cylinder is arranged in the mounting rod, the piston cylinder is communicated with the communication pipe, a piston is arranged in the piston cylinder, and the piston is connected to a foot pedal for a user to compressthe air by foot pedaling. The bicycle solves the problems that the friction force of the existing bicycle brake is not uniform and the braking of the front and rear wheels cannot be simultaneously achieved.

Description

[0001] This application is a divisional application of an invention patent application named: An air brake bicycle, with the application date: June 25, 2016, and the application number: 201610469287.1. technical field [0002] The present invention relates to a bicycle, and more particularly to a bicycle with air brakes. Background technique [0003] A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. The braking system of the bicycle is also different. The common one is the handbrake, and the other is the dead fly bicycle. Its rear axle is fixed so that it can be braked by stepping back with the foot. [0004] During the use of existing bicycles, the front wheels and the rear wheels of the bicycle need to be braked separately when using the brakes, and the direction of the handlebars needs to be control...

AI Technical Summary

Problems solved by technology

[0004] During the use of existing bicycles, the front wheels and the rear wheels of the bicycle need to be braked separately when using the brakes, and the direction of the handlebars needs to be controlled when braking at the same time. This is not conducive to the safety of the user in some dangerous situations. Safe, at the same time, the existing hand brake, due to the wear of the brake pads, will cause the wheel to deflect during braking, making it difficult to control the direction of the bicycle, which will have a bad impact on the user
