🔩 Input Shaft – Leyland L/L-2518
📌 Definition
The input shaft is the shaft that connects the clutch output to the gearbox. In the Leyland L/L-2518 truck, it transfers engine torque into the gearbox, where the gears then transmit power to the propeller shaft and ultimately to the axles.
It is a critical driveline component, responsible for smooth power delivery and proper engagement of gears.
⚙️ Key Features
Material: High-strength alloy steel, usually heat-treated to resist wear and fatigue.
Spline Teeth: The end that engages the clutch plate has splines to mesh with the clutch disc hub.
Gearbox Engagement: The other end connects to the gearbox input, supporting smooth gear meshing.
Bearings Support: Typically runs on input shaft bearings inside the gearbox, which handle radial and axial loads.
Dimensions: Specific to Leyland L/L-2518, with lengths, diameters, and spline counts matching the gearbox model (usually Eaton or AL type used in L/L series).
🛠️ Function
Torque Transmission: Transfers engine torque from the clutch to the gearbox.
Gear Engagement: Supports smooth rotation of gears inside the gearbox, allowing the vehicle to move in different speeds.
Durability: Must withstand high torque peaks, vibrations, and load changes.
