Bicycle accessories flywheel effect

Bicycle frame, tires, pedals, brakes, chains, etc. 25 accessories, the basic components are indispensable. Wherein the frame is a bicycle frame, the weight of people and goods which it is subjected maximum. According to the characteristics of the various parts of the work can be broadly divided into guide system, drive system, braking system. Bicycle accessories bicycle body is referred to all parts and accessories. According to a large body frame structure can be divided into: the frame, tires, pedal parts, assemblies fork, chain, flywheel and other categories. Then you know the basic principles of bicycle accessories flywheel do?
Within screwing flywheel fixed to the right end of the rear axle of the tool in the same plane with the sprocket, and by a chain and sprocket drive system constituting the bicycle. From the structure can be divided into single-stage and multi-stage flywheel flywheel two categories. Single-stage flywheel is also known as a single piece flywheel sprocket, mainly by the jacket, and the flat core block, extremely heavy, extremely heavy spring, washers, wire block a few balls and other parts.
Its single-stage flywheel works: When moving the foot pedal forward is chain driven flywheel rotates forward, this time within the flywheel and extremely heavy phase containing the rotational force transmitted to the flywheel by extremely heavy core, the core and the rear axle drive the rear wheel, the bike advances.
When you stop pedaling movable pedals, chain and coat it does not rotate, but the rear-wheel drive in the inertia of the core and still extremely heavy rotating forward, then the inner tooth flywheel relative sliding, thereby compressing the core to the core within the sub-notch, extremely heavy and extremely heavy compression spring. When extremely heavy flywheel addendum slide inside the top teeth, extremely heavy spring is compressed the most, and then slide forward a little bit, to be extremely heavy to extremely heavy spring playing on the tooth root, issued a "blah" sound. The core is rotating faster, extremely heavy quickly slides on the tooth in each flywheel, issued a "blah" sound. When the reverse stepped on the foot, jacket reverse rotation, the slide will accelerate extremely heavy, so "blah" sound more rapid. Multi-stage flywheel transmission is a bicycle is an important component.
Multi-stage flywheel is based on single-stage flywheel, adding a few slices flywheel sheet, in combination with sprocket shaft, composed of a variety of different transfer ratio, thus changing the speed of the bicycle.
