Pinion Coupling – Tata Ace Super (26‑T) — Description
The Pinion Coupling (26‑T) for Tata Ace Super is a drivetrain connection component used in the propeller shaft / rear axle assembly of the vehicle. It is sometimes also called a pinion flange or coupling flange in automotive parts catalogs.
What It Is:
A pinion coupling is a splined flange‑type part that connects the propeller (drive) shaft to the pinion gear or differential input.
The designation “26‑T” means the coupling has 26 splines/teeth, matching the corresponding splined shaft it mates with in the driveline.
Function & Role:
Torque transmission: It transmits rotational power from the propeller shaft into the rear differential/pinion gear, enabling engine torque to reach the rear wheels.
Secure driveline connection: The splined interface ensures a tight mechanical fit that can handle the vehicle’s load and torque without slipping.
Alignment & stability: Provides proper alignment between the shaft and gearbox/pinion assembly, helping reduce drivetrain vibration and wear.
Where It Fits:
Installed at the end of the propeller shaft where it engages the pinion gear input/differential flange in the Tata Ace Super’s rear axle system.
In simple terms, the Pinion Coupling 26‑T on a Tata Ace Super is a splined connection flange that securely joins the drive shaft to the differential’s pinion gear, absorbing torque and keeping the driveline aligned for smooth power delivery.
