    Rod Steering
AI Thread Summary
The discussion clarifies the terminology related to the Triumph Herald's steering components, specifically distinguishing between the stub axle, kingpin, and tie rod. The stub axle refers to the horizontal part with wheel bearings, while the kingpin is associated with the vertical steering bearings. The tie rod is identified as the thinner, horizontal rod that transmits turning torque from the steering box. Participants also mention the possibility of separating components of the stub axle using heat and force. The Triumph Herald is noted as an unusual vehicle in the US market.

TL;DR Summary
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.

my wife's first car was a Herald. An oddity in the US.

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter.
