Classification and functions of core components for locomotive parts
Jul 17,2025
Engine and accessories
Core components: cylinder, piston, crankshaft, camshaft, spark plug, carburetor/electronic fuel injection system.
Function: As the "heart" of the locomotive, responsible for power output and combustion efficiency. For example, high-performance spark plugs can improve ignition stability, and electronic fuel injection systems can accurately control fuel injection, optimizing power and fuel consumption.
Material: Pistons are mostly made of aluminum alloy, while crankshafts are commonly made of high-strength alloy steel to withstand high temperature and high pressure environments.
drive system
Core components: clutch, gearbox, chain/belt, sprocket.
Function: Transmit engine power to the wheels. Chain transmission is suitable for high torque scenarios, while belt transmission is quieter and has lower maintenance costs.
Example: Competitive motorcycles often use high-strength chains (such as 520/530 specifications) to withstand extreme tensile forces.
brake system
Core components: brake discs, brake pads, brake fluid, ABS module.
Function: Ensure braking distance and directional stability. High performance brake pads (such as ceramic materials) can reduce thermal attenuation, and ABS systems can prevent wheel lock up.
Data: The lifespan of ordinary brake pads is about 10000-20000 kilometers, while high-performance products can reach over 30000 kilometers.
suspension
Core components: front fork, rear shock absorber, spring, air cylinder.
Function: Absorb road vibrations, improve handling and comfort. Multi link suspension is suitable for heavy-duty locomotives, while independent suspension is commonly used for scooters.
Adjustment: It can be adapted to different road conditions and loads through preloading and damping adjustment.
Electrical appliances and instruments
Core components: battery, generator, igniter, dashboard, LED lighting fixtures.
Function: Provide power support and display vehicle status. Lithium batteries are lighter and charge faster than traditional lead-acid batteries.
Trend: Full color TFT instruments are gradually becoming popular, supporting intelligent functions such as navigation and Bluetooth connection.
walking system
Core components: frame, wheel hub, tire, mudguard.
Function: Support the weight of the vehicle and transmit power. Aluminum alloy wheels are lighter than steel wheels, improving acceleration performance.
Tire selection: Sports motorcycles prefer semi hot melt tires (strong grip), while long-distance travel vehicles choose all terrain tires (good wear resistance).
General parts and accessories
Core components: fuel tank, seats, bumper, tool kit, side box.
Function: Improve vehicle functionality and personalized needs. Quick detachable side boxes can improve cargo convenience, while memory foam seats can alleviate long-distance fatigue.
