Pinion Coupling – Tata Magic N/M (23-T) — Description
The Pinion Coupling (23-T) for Tata Magic N/M (Old Model) is a driveline component used in the rear axle / propeller shaft assembly of the vehicle. Its main role is to connect the propeller shaft to the pinion gear assembly so that engine torque is transmitted into the differential and onward to the wheels.
What it is:
A pinion coupling (often referred to as a flange coupling or pinion flange) is a part that mates the splined end of the drive shaft to the pinion gear input in the differential.
The “23-T” designation means the coupling has 23 splines/teeth, matching the splined shaft it connects to, ensuring proper fit and torque transfer.
Function:
Transfers torque: It connects the rotating propeller shaft to the pinion gear, allowing power from the gearbox to enter the rear axle assembly.
Ensures alignment: Provides a secure and aligned joint between shafts so torque flows efficiently without vibration or misalignment.
Absorbs driveline loads: Handles the rotational forces within the driveline during acceleration, deceleration and load changes.
Where it fits:
Installed at the rear end of the driveshaft where it bolts or splines into the pinion gear flange of the rear differential.
In simple terms, the pinion coupling is a critical connection between the drive shaft and the differential pinion gear that enables the Tata Magic’s rear wheels to be driven by engine power.
