Design Fault?

[NortonF1]

When I look at the latest drawings and pictures from what VV (or now Persu) are planning I see a big difference to the Carver One as there is only a forward connection between the engine section and the bodywork.

I dont think that will work as like in the Carver one You need an additional rear support for the passenger compartment or You will get a massive bending force at that foreward joint and also an overall stability problem for the whole vehicle.

What do You guys think about that?

According to info released by Persu Motors the rear connection is not necessary and they have also strengthened the front connection and used Teflon in the process.
So, I guess we wait and see since we haven't seen a road tested vehicle with this design.

And I say it will not work that way!

Think about it, every bump on the road, all side forces and all lateral stability would have to be absorbed at that one bearing, together with the torque from the tilting mechanism!

What are You willing to bet?

It's a pipe why would a pivot point on the back make it that much stronger? Since this was developed with the Carver team and Carver Eng. even has specs for a similar one point design in their released documents why would this be suspect? Carver was even asked this in early development and they are the ones that said this was doable according to the Persu team.

If you have some insight into this other than a gut-feeling it would be interesting.

Why do You have an upper and a lower arm in every wheel suspension?

Ah ...you don't...

[NortonF1]

Ah ...you don't...

Add: every good wheel suspension!

[NortonF1]

Look at the front of the Carver One and see how "beefed up" that is!

[AZEqualizer]

Add: every good wheel suspension!

Because it is not used with every good wheel suspension.

Your all encompassing statements do much to dilute your discussion. I can think of multiple suspension systems that don't use a upper and lower arm for suspension with out even trying.

Seems like you are just stating feelings not facts to substantiate anything.

[AZEqualizer]

And now we have gone from a rear end discussion on piviot points to a discussion of how to impliment a single sided swing arm? BTW single sided swing arms have been around since the 1940's

And the other side looks like thishttp://www.carver-worldwide.com/UplFiles/Pictures/_D7U0945.jpg

So what point are you trying to make?

Well if You are right, why in Your opinion did Carver go the "hard" way of having a rear support if it isn´t neccessary?

[AZEqualizer]

Because it is Version 1.... Why has Carver Eng. published multiple articles showing advanced designs without the rear support?
And where is the upper arm part of the suspension in the single arm suspension?

This is becoming a useless discussion ....

I'm new to the club, but seen that Norton is from Germany, and actually owns a Carver. I would like to see some more photographs of your vehicle!

no:p:i:c1

Hi Spock,

I have lots of photos but I would need an easy way to upload....

Hi, Spock:

You can go to your User CP and click on "Pictures and Albums" to begin compiling your photos. You'll want to make sure the pictures comply with the following limits:

Picture Limits: Pictures Remaining 60 Maximum File Size per Picture 97.7 KB Maximum Picture Dimensions 600 by 600 Pixels Pictures will be automatically resized to fit within these constraints if possible. However, you may receive better results by doing it manually.


We'd love to see images your Carver on the road.

What is a car suspension system if not single-sided..? I don't recall seeing many car wheels from the last hundred years or so whcih required an outboard bearing with additional loadpath support as well as an inboard one...

This is a meaningless concern as long as the stated beefing-up has taken place.

A washing machine rotates at 1,000 rpm on a single offset-mounted bearing and generates off-centre forces when loaded far in excess of anything that a vehicle can generate yet I bet you have one in the home, eh Hans!?

What is a car suspension system if not single-sided..?

A car suspension usually has an upper and a lower arm, or some other way of multiple suspension.

On a tilting vehicle we are talking about a passenger compartment of (at least) 600 pounds that is connected to an engine compqartment of at least the same weight.

That (single ) joint would have to take the bending moment, the side forces (at 45 degrees = 2g!), the acceleration and decelaration and the forces of the tilting hydraulics (remember, the Carver One goes from 45 degrees left to 45 degrees right in 1.1 seconds) and all that without binding - that joint would have to be super massive!

I am still willing to take bets that a roadgoing VV, Persu or whatever will have a rear support!

[ziggy951]

I will take that bet. I'll bet you the first one (V1/Persu/Pursue/Etc) off the production line delivered to my garage.... that it doesnt have a rear support.
