The basic principle of flywheel in bicycle accessories?



Bicycle frame, tires, pedals, brakes, chains and other 25 accessories, the basic components are indispensable. Among them, the frame is the skeleton of the bicycle, it is the people and the weight of the goods the largest. According to the characteristics of the work of the accessories, can be roughly divided into guidance system, drive system, brake system. Bicycle accessories are collectively referred to as all parts and accessories of the bicycle body. According to the body structure of the frame can be divided into: frame, tires, pedal parts, fork components, chain, flywheel and other major categories. So do you know the basic principles of flywheel in bicycle accessories?
The flywheel is screwed to the right end of the rear axle, which is in the same plane as the sprocket and connected to the sprocket through the chain to form the driving system of the bicycle. From the structure can be divided into single-stage flywheel and multi-stage flywheel two categories. Single-stage flywheel, also known as single-sprocket wheel flywheel, mainly by the jacket, flat and the core, jin, Qianjin spring, washers, wire block a few steel balls and other components.
Its single-stage flywheel works: When the pedal is to move forward, the chain drive the flywheel forward, when the flywheel teeth and jin phase, flywheel rotation force through the kiln spread to the core, the core drive the rear axle and The rear wheels turn and the bike is on.
When the foot pedal is stopped, the chain and the jacket do not rotate, but the rear wheel still drives the core and the jar forwards under inertia, and the flywheel inner teeth are relatively slid, thereby compressing the core to the core Sub-mouth of the mouth, the pounds and compressed a thousand jin spring. When the jackets slide to the top of the flywheel at the top of the teeth, the 1000 spring is compressed most, and then a little forward slide a little, jin jin jin spring to the tooth root, issued a "blah" sound. The core rotation to speed up, also quickly in the various flywheel teeth on the sliding, issued a "blah" sound. When the reverse pedal, the coat reverse rotation, will accelerate the jin the slide, so that "blah" sound more rapid. Multi-stage flywheel is an important part of a bicycle transmission.
Multi-stage flywheel is based on the single-stage flywheel, adding a few pieces of flywheel, combined with the sprocket on the center to form a variety of different transmission ratios, thus changing the speed of the bike.
