I find it difficult to credit the coach moving down the hill with 20,000 - 40,000 lbs of motorhome pressing the jack pads into the earth. That assumes the jacks are rated for the full coach weight and don't break under the load. My 36,000 lb coach had 4 x 16,000 lb jacks, so I wasn't too worried. Back in the day some coaches had poor frame rigidity, especially up front, so the front cap and windshield frame would often twist if the front wheels came off the ground. My '96 Southwind (F53 chassis) was like that and I avoided ever lifting the front to even barely touching cause the windshield would start to move. My 2002 W22 chassis coach didn't seem to have any problem with that but I was still careful. My 2004 DP was stable as a mountain no matter how much it was jacked. Spent many a summer at my brothers home in SW PA with wheels off the ground. He lives on a hill side and the 2012 Tour never had a problem.
But some damage simply can't be repaired. The replacement cost can run into the thousands. Ames estimates that her shop welds approximately 250 to 500 seriously damaged wheels a year, indicating just how serious the problem is in this region.
Why reinvent the wheel? Because sometimes it makes for a better bike. Loopwheels are a completely new type of bicycle wheel, designed with a unique built-in suspension that makes for a delightfully smooth ride. Instead of spokes, as on a traditional bicycle wheel, the Loopwheels have three loop-shaped springs that allow the wheel to absorb the vibrations and bumps most riders are accustomed to feeling.

Meanwhile, Rozanes said the company is developing a prototype for bicycles called the Fluent and hopes to move on to other devices down the road. Reinventing the wheelchair for children in need Mom's invention lets special-needs children walk for the first time From wooden to wondrous: The technology of wheelchairs
Wheelchair design has evolved in recent years but users can still find it demanding to propel themselves. That can be especially difficult and uncomfortable on rough surfaces such as cobbles and paving stones.
More advanced details about this project can be found in an interview conducted in Korean after he won the award.

People out there lucky in the sense that they know how to ride a bike but unlucky in the sense that doing so jars their spines and brains and generates great discomfort in the crotchal region, say hello to Loopwheels. Loopwheels are 20" bicycle wheels with built-in spring systems between their hubs and wheel rims that provide suspension and cushioning from road bumps and potholes. So that everyone who finishes a Loopwheeled bike jaunt does so with lumbar vertabrae, tailbone, and rectum as intact as they were before the ride began.

The way the loop-ends overlap each other, it looks like that would give some lateral stability.
Loopwheels are a British manufacturer of world-class innovation in wheel technology. The Loopwheel is a new type of suspension wheel which reduces vibration and impact on wheelchairs and bikes.

Richard Quest, the designer of LoopWheel, asks “Why can’t the suspension work in all directions?” in regards to conventional wheels. Hence, the idea of LoopWheel originates. A 20-inch Loopwheel with Shimano Alfine 11-speed hub weighs 2.13kg. A LoopWheel is about 300g heavier than a conventional spoke wheel of the same size. However, you do get the added suspension and a smoother ride.
Innovative design means the wheel has a stiff structure but an element of compression. The springs within the wheel are made of a carbon composite material.
We also carry a wide variety of upgraded suspension bushings. Refreshing the old, worn out bushings in your car with fresh polyurethane bushings will improve your ride quality and handling. Polyurethane bushings outperform and outlast OEM rubber bushings and can withstand racing conditions. Upgrade your bushings to reduce wheel hop, improve stability and increase control.

There are various ways of attaching the wheels of the car so that they can move up and down on their springs and dampers , and do so with as little change as possible in the distance between adjacent wheels or in the near-vertical angle of the tyres to the road.

Currently, this is just a concept with renderings, no prototype or production is planned.
'I suddenly wondered why the wheel couldn't have its own suspension, and quickly drew the idea down - and then did nothing about it for two years.

The Loopwheel works using three heavy duty springs instead of spokes. When the rider hits a bump, the springs compress to give a smooth ride
With every rotation the springs will bend and absorb a amount of energy. Normally this is called “damping”. Its pretty useful in some cases. But it’s pretty unusual to damp a rotation of wheels, because this will slow down the straight moving. For Bicycles (and all other vehicles) you should mount your springs in the direction where the impact is coming from plus a additional damper to stop the bouncing of the spring.

A roda para suportar tensões radiais e axiais o conjunto de amortecedores e a jante precisam serem reforçados, inevitavelmente adquirindo mais massa de material, sem falar na aerodinâmica prejudicada.

Maybe I’m wrong but wouldn’t the wheel react differently every time you hit the same obstacle depending on how the shocks are pointed? Bartthebikeman on May 20th, 2016 - 2:58pm
People have tried to make a wheel with suspension before but they have never had the right combination of design and materials.
Daniel Barel, the CEO of SoftWheel, told the Jerusalem Post that his company’s new suspension technology is an integral part of the wheel that is selective and symmetric.
It will never be perfect, there will always be slight compromise. Now, we have three to contend with. Tony on May 21st, 2016 - 1:24am
The big limitation that I can see, is that if there is any deflection when the rider gets on the bike, that means that the rider is essentially pedaling uphill all the time (Because he has to compress the springs as he moves forward). The other problem is that unless the springs are precisely calibrated to the riders weight this will really destroy the rolling efficiency of the bicycle. Malcolm Jacks May 23, 2020 03:09 AM

It's unclear at this point whether you'd lose any forward motion energy due to torque flex, but that can be tuned out of the system if required in any case. It's also unclear how much a pair of wheelchair-sized ASWs would cost at this point. We assume they're not cheap compared to a regular rim and tire setup. Here's some annoyingly infomercial-style video comparing regular wheelchair wheels to an ASW setup over curbs and grassy, uneven terrain.
