Use and classification of bicycle forgings

Bicycle forging refers to the processing of metal materials into specific shaped parts through cold and hot forging processes, which are used to assemble various parts of the bicycle. Bicycle forgings are usually made of carbon steel, alloy steel and other materials, with high strength, fatigue resistance, wear resistance and other characteristics.

The use of bicycle forgings mainly includes the following aspects:

1. Rotating parts: pedals, crankshaft, central shaft and other parts in bicycles are usually made of forgings to transmit the power of human riding.

2. Connecting parts: The chain, sprocket, rear wheel hub and other parts of the bicycle are connected with forgings to ensure the robustness and reliability of the vehicle structure.

3. Brake components: brake rod, brake claw and other components of the bicycle can also be manufactured by forging to ensure the sensitivity and braking strength of the brake.

4. Suspension components: Some advanced bicycle suspension systems must use forgings to withstand and alleviate ground vibration, improve riding comfort and stability.

5. Other parts: Bicycle seat tube, front fork, handlebars and other parts can also be manufactured with forgings to meet the design requirements of different models and needs.

Depending on their function and shape, bicycle forgings can be divided into several categories, such as:

1. Pedal class: mainly used for pedal power conversion, usually forged by carbon steel.

2. Crankshaft type: used to drive connecting rod and chain rotation, usually forged by alloy steel.

3. Central shaft class: responsible for installing the crankshaft and pedal, usually forged by alloy steel, and connected with the crankshaft.

4. Chain type: mainly forged by carbon steel, used to connect the front and rear wheels and sprockets.

5. Brake claw type: used to apply pressure to the wheel hub when braking, usually forged from carbon steel.

6. Handlebars: used to control bicycles, usually forged by aluminum alloy, while having certain strength and lightweight requirements.

The above is only part of the use and classification of bicycle forgings, in fact, there are more types and applications.
