- The core support is mounted on the engine crankshaft main shaft, ensuring smooth operation at high crankshaft speeds.
- It reduces wear and effectively reduces metal-to-metal friction, improving engine smoothness and life.
- Its strong load-bearing capacity withstands the high loads and high-speed impacts of high-speed engine operation.
- Precision manufacturing utilizes high-precision machining processes to maintain axial and radial stability.
- Noise control reduces crankshaft vibration and noise, improving riding comfort.
- The function of the combination of the crankshaft and connecting rods converts the reciprocating motion of the piston into the rotational motion of the crankshaft, and outputs power.
- The connecting rod transmits the motion and power of the piston to the crankshaft, which pushes the crankshaft to rotate.
- The crank bearing receives the force from the connecting rod and converts it into a torque about its own axis, which is then transmitted to the transmission system, while driving the train and some other auxiliary devices.
