Problems solved by technology

However, it has been found in practice that the structure of the bicycle center shaft assembly is unreasonable. The center shaft assembly is often prone to problems, has a short service life, is inconvenient to install and disassemble, and the right bevel gear is easy to swing, which seriously affects the forward and reverse rotation of the pedals. For this reason, the center shaft assembly of the bicycle needs to be improved, and the right one-way bearing shaft of the bicycle driven by the forward and reverse rotation of the pedals needs to be explored.

Abstract

The invention relates to a bike centre axis assembly, in particular to a right one-way bearing shaft of a bike driven by a forward-reverse rotation of a foot pedal. The right one-way bearing shaft of the bike driven by the forward-reverse rotation of the foot pedal is characterized in that an inner threaded through hole is formed along the axis of the shaft, the inner threaded through hole is a reverse threaded tooth, the right one-way bearing shaft is sequentially provided with an outer threaded end, a shaft neck, a chain plate connection plate and a shaft shoulder from left to right, the chain plate connection plate is provided with chain plate connection threaded holes, and the shaft neck is provided with a key groove. The right one-way bearing shaft of the bike driven by the forward-reverse rotation of the foot pedal is unique and ingenious in design, easy to manufacture, long in service life, convenient to mount, detach and maintain and good in trial effect, it is beneficial for solving the problem of swing of a bevel gear on the right side, reliability of a shaft assembly in the bike driven by the forward-reverse rotation of the foot pedal is remarkably improved, and the right one-way bearing shaft is one of key parts of a shaft assembly in the bike driven by the forward-reverse rotation of the foot pedal.

Description

technical field [0001] The invention relates to a central shaft assembly of a bicycle, and more particularly to a right one-way bearing shaft of a bicycle driven by pedals in forward and reverse rotation. Background technique [0002] Bicycle is mainly made up of parts such as vehicle frame, central shaft assembly, rear wheel, front wheel, chain, chain disc, flywheel, pedal, brake, and the central shaft assembly structure of existing bicycle is relatively simple, mainly consists of central shaft Seat, axle, bearing, chain plate, crank etc. are made up, and general-purpose bicycle is all one-way drive, promptly drives bicycle when stepping on left and right feet forward. On February 19, 2012, the inventor applied for a bicycle driven by the forward and reverse rotation of the pedals. The bicycle driven by the forward and reverse rotation of the board successfully realizes the bicycle bidirectionally driven by the pedal. However, it has been found in practice that the struct...
