1. Core Power Input and Torque Transmission
As the primary interface between the engine/motor and the transmission system, the 018CHA-1509100 input shaft serves as the critical component for receiving and transferring power. The shaft’s front end (equipped with a splined or flanged connection) directly mates with the torque converter (in automatic transmissions) or clutch assembly (in manual/dual-clutch transmissions), capturing rotational power from the power source. It then transmits this torque to the main gear set via its integrated splines or gear teeth, enabling the transmission to adjust speed and torque ratios according to operating needs. Without this function, the transmission would be unable to receive power, making the input shaft essential for the operation of the entire powertrain.
2.Clutch Engagement and Disengagement Coordination
In transmissions with clutch systems (e.g., manual, AMT, or DCT), the 018CHA-1509100 input shaft plays a key role in coordinating clutch engagement and disengagement. The shaft’s smooth, precision-machined outer surface provides a stable mounting for the clutch disc, ensuring uniform contact pressure when the clutch is engaged. During disengagement, the shaft’s low-friction coating allows the clutch disc to slide freely, preventing drag that could cause gear grinding or increased wear. Additionally, the shaft’s splines are designed to absorb minor axial movements of the clutch assembly, maintaining proper alignment even as components heat up and expand during operation—this alignment is critical for smooth clutch operation and extended clutch life.
1. Premium Material Strength and Wear Resistance
The 018CHA-1509100 transmission input shaft is manufactured using high-quality chrome-molybdenum alloy steel, a material renowned for its exceptional tensile strength and fatigue resistance. Through a rigorous heat treatment process (including quenching and tempering), the shaft achieves a surface hardness of up to HRC 58-62 and a core toughness of ≥1200 MPa, enabling it to withstand the intense torque and rotational forces generated during power transmission. Compared to standard carbon steel input shafts, its wear resistance is enhanced by over 50%, effectively preventing premature wear caused by friction with clutch discs and gear hubs. Even under long-term high-load operation (such as frequent start-stop cycles in urban driving or heavy-duty industrial applications), the shaft maintains dimensional stability, avoiding deformation that could lead to transmission jitter or failure.
2. Precision Machining for Optimal Transmission Accuracy
Every 018CHA-1509100 input shaft undergoes ultra-precision machining using CNC turning and grinding centers, with a dimensional tolerance controlled within ±0.005 mm and a surface roughness (Ra) of ≤0.4 μm. This high-precision manufacturing ensures perfect concentricity between the shaft’s main body, splines, and bearing journals—critical for minimizing rotational runout during operation. The spline teeth (designed with a modified involute profile) feature a contact area of over 90% when mated with the clutch hub, ensuring uniform torque distribution and reducing localized stress concentrations. This precision not only eliminates power loss caused by misalignment but also reduces noise and vibration during gear shifts, enhancing the overall smoothness of the transmission system.
