🔩 Centre Coupling – Leyland L/L Taurus 1616 (Round, Serrated)
📌 Component Overview
The centre coupling flange (centre joint coupling) is a driveline component used in heavy trucks with a multi‑section propeller shaft (such as the Leyland L/L Taurus 1616). Its job is to join the front and rear propeller shaft sections, allowing torque to transfer smoothly while accommodating slight angular and axial movements due to suspension travel or chassis flex. It typically has serrated/splined faces and a bolt pattern that matches the propeller shaft yokes.

🛠️ Function in the Drivetrain
The centre coupling flange sits between two sections of a multi‑piece propeller shaft. Its roles include:
Torque Transmission: Transfers rotational power from the gearbox through the driveline to the rear differential.
Flexible Engagement: Serrated/splined faces provide a positive mechanical lock to the mating yokes.
Movement Compensation: This coupling allows slight angular and axial movement between shaft halves as the truck moves over uneven surfaces — essential in heavy vehicles like the Taurus 1616.
