📌 Centre Flange (Serrated) – Leyland U Truck
Product Type: Coupling / Centre Flange (Serrated)
Application: Ashok Leyland U Truck heavy-duty commercial vehicles — used in the driveshaft / propeller shaft / differential coupling system.
🔧 Function & Purpose
The centre flange is a mechanical coupling component that connects sections of the driveshaft or couples the driveshaft to the gearbox/differential unit. It provides a robust torque transmission interface and maintains alignment between rotating shafts. The serrated design (corrugated or toothed contact surface) improves the grip and mechanical engagement between mating parts, reducing relative movement under load and enhancing reliability in high-torque truck applications.
🛠️ Key Features
Serrated Interface:
The serrated surface ensures positive engagement with the mating yoke or shaft end, minimizing backlash, slip, and vibration under heavy load conditions often encountered in commercial trucking.
Coupling Function:
Acts as a centre joint between the propeller shaft and adjacent drivetrain components (gearbox/differential), especially where a centre bearing or intermediate support exists.
Spline / Bolt Pattern:
Typical Leyland centre flanges for U-Truck variants have specific number of splines and bolt hole configuration that match the truck’s driveshaft and mating yoke. While exact values vary by model, part catalogs show centre joint couplings for Leyland have multiple splines and 4–8 bolt holes on a plate approx. 175 mm diameter in similar series parts.
Material & Durability:
Made from high-strength forged or machined steel to withstand high torsional forces and repeated cyclic loading common in commercial vehicle drivetrains.
