Half Yoke — Tata Intra (for CROSS‑4194P / Universal Joint) — Description
A half yoke in the Tata Intra’s propeller shaft assembly is a driveline component that works with the universal joint (U‑joint) cross (spider) to transfer power from the gearbox to the rear axle while allowing angular movement between shafts.
Basic Function & Role:
The half yoke is one of the two yoke halves that flank the universal joint cross. The cross has four arms; two arms sit in this half yoke and the other two sit in the mating yoke.
It holds the bearings/caps of the U‑joint cross securely, so the driveshaft can transmit torque even when the angles between shafts change during driving. This is typical in rear‑drive and commercial vehicle propeller shafts, including on the Tata Intra.
How It Works:
The U‑joint cross sits between the two yokes — this half yoke and its companion yoke — forming what’s commonly known as a universal joint.
When the vehicle encounters bumps or the suspension moves, the angles between the transmission output shaft and the differential or driveshaft vary. The half yoke, together with the cross, lets the shaft flex and rotate without binding.
Where It Fits:
Installed on one side of a universal joint location in the propeller/drive shaft of the Tata Intra — typically where the shaft attaches to the transmission output or to an intermediate shaft.
The designation CROSS‑4194P (for the cross) indicates the specific size and type of universal joint this half yoke is designed to mate with, so you get proper fitment and torque transmission.
In simple terms:
The half yoke is a support arm of the propeller shaft’s universal joint that, together with the cross and companion yoke, lets the driveshaft transmit torque while accommodating angular movement and suspension travel
