🔩 Centre Coupling – Leyland L/L Taurus 1616
📌 What It Is
The centre coupling flange (also called centre joint coupling) is a driveline component used in multi‑section propeller shaft assemblies on heavy trucks like the Leyland L/L Taurus 1616. This flange joins the front and rear halves of the propeller shaft (or intermediate shaft to shaft), allowing rotational torque transmission while accommodating slight movement and misalignment caused by chassis flex and suspension travel. The coupling typically has serrated/splined faces and bolt holes that mate with the same pattern on the mating yoke or shaft.

🛠️ Function in the Drivetrain
Torque Transmission: It carries torque from the gearbox through the propeller shaft to the rear axle differential.
Flexible Engagement: Serrated/splined interface ensures positive engagement and helps reduce backlash/vibrations.
Motion Accommodation: Allows slight misalignment between shaft sections due to road and suspension movement.
