SUMMARY

The discussion clarifies the terminology related to the steering components of the Triumph Herald, specifically identifying the "stub axle" and "kingpin." The tie rod is defined as the component that transmits turning torque from the steering box. Participants emphasize the importance of distinguishing between the stub axle, which is a short axle supporting the wheel, and the kingpin, which is involved in steering. Additionally, the discussion notes that the vertical link can also serve the function of a kingpin in the Triumph Herald's suspension system.

TL;DR
Hi guys, this might be a silly question. I have attached a picture to this thread. Am I right to refer to the component ( shown with the red dash line ) as the steering tie rod? If not, what is the name for that rod?
Thank you

No I would call that the "stub axle" or perhaps the wheel spindle. The tie rod is the thing that supplies the turning torque from the steering box.

Thank you so much
 
The horizontal part with wheel bearings is the stub axle.
The near vertical part with steering bearings is the kingpin.
Since it is all one casting on a tractor it is called a “kingpin / stub axle”, or some similar combination.

I believe the piece doing the job of a kingpin can also be called the Vertical Link (Triumph Herald suspension parts list).

But Stub axle describes perfectly the broken part. A wheel fits on an axle and the axle, in that case is just a 'stub' (short). You could have some fun, separating the two parts of that component in the photo. Heat, cold and steady force but no bashing if you can help it

The tie rod is the thinner, horizontal rod at top left of the photo.
