A coach wheel

It is a print of Rhino not a render image.

Hi @sciensman,

To make a stronger wheel you should dish the spokes and also extend the back of the hub, then shrink iron bands around the front and back of the hub. I don’t know what the round things are but you wouldn’t want to drill into felloes or hub - that would really weaken the wheel. Surface decoration, if that is what they are, would of course be fine.

You are right, senior

I modeled the wheel based on my technical imagination, not experimentally.

I have not seen a real cart or coach wheel many years, except when I was a child. But as far as I remember, the spokes of the wheel I saw were not dished. I also didn’t refer to the internet to visit such the wheel, but thought, the metal strips with the nails can reinforce the wheel.
Of course, I think, the wheels of a coach is finer than the wheels of a rough cart, so I tried to model it thinner as much as possible.

However, your technical insight is closer to reality than my fantastic modeling :slight_smile:

I found this real wheel in the internet and its spokes seem to be similar to the spokes I designed

I found a picture for you, illustrating the dish in the wheel. It isn’t a huge amount. Notice how the axle is angled down slightly so that the spokes are vertical when at the bottom of the wheel.

Here’s another view showing the wheel being fitted.

Here is the bare axle (the jack is not from the same period!).

These are pictures of an 18th century English Mail Coach under restoration in 2019.


(Sorry, the colouring of this image is bad - the red should be bright as in the other pictures).

Hope you find that interesting.

Many thanks :slight_smile:

Yes, it actually was useful for me. But I am thinking; why the ring should be further than the straight line between the hub and ring (like a dish)?

Is it because, the ring keeps away from the chassis, or it is for balancing the forces between axle and ring?

It increases the space between the top of a pair of wheels so you can fit more in and it makes the wheel stronger in respect of cornering forces.
