Bicycle Accessories Flywheel

The flywheel is screwed and fixed on the right end of the rear axle and is in the same plane as the sprocket. The flywheel is connected with 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 flywheel, mainly by the jacket, flat block and core, extremely heavy, heavy spring, gasket, wire block and other parts.
Its single-stage flywheel works: when the pedal is to move forward, the chain driven flywheel forward rotation, then flywheel internal gear and heavy phase with the flywheel of the rotating force through the kilo spread to the core, the core driven rear axle and The rear wheel rotates and the bicycle advances.
When the foot pedal is stopped, neither the chain nor the outer casing rotates, but the rear wheel, under inertia, still drives the core and the jacks to rotate forward, whereupon the inner teeth of the flywheel are relatively slid, thereby compressing the core to the core Child of the slot, the extremely heavy compression of the spring. When the top of the tooth to the top of the flywheel tooth, the spring is compressed to the most, and then a little bit slippery forward, heavy jin was bombarded to the tooth root, the issue of "blah" sound. Core rotation to speed up, extremely fast in each flywheel on the internal tooth slide, issued a "blah" sound. When the reverse pedal pedal, the jacket reverse rotation, will accelerate the jin of sliding, so that "blah" sound more rapidly. Multi-stage flywheel is an important part of the bicycle transmission.
Multi-stage flywheel is a single-stage flywheel, based on the increase in a few pieces of flywheel, and the sprocket on the axis of the combination of the composition of a variety of transmission ratio, which changed the speed of the bike.
