A business supported by Innovate UK has designed a wheelchair with suspension that is improving the comfort of users across the globe. From: Innovate UK and UK Research and Innovation Published 21 June 2019 A £24,000 Innovate UK grant in 2013 helped them to develop the loopwheel for wheelchairs, and a further £240,000 grant in 2017 allowed them to partner with other companies.

According to Pearce, one of the advantages of Loopwheels is the fact that unlike a suspension fork, they can absorb shocks delivered not just from underneath or above but also from the front (as might happen when running into a curb head-on). He also admits that many other inventors have come up with designs for wheels with tangential suspension over the past hundred years or so, although he believes that today’s modern materials will allow his to work where others have proved impractical.

Usually the half-axle is broadened into a V with front and rear pivots to keep it from twisting. Pivots allow the bar to twist, but to a limited degree so that rolling is controlled.
TPMS sensors are available for an additional cost. For wheel and tire packages, the price includes free installation of the sensors. Note: some vehicle models or sensors may require a re-programming process to sync with the new sensors. This can be done fairly easily by an auto dealer or repair shop (the cost to program sensors is the customer’s responsibility). If the wheels you need the caps for were purchased from us, yes we can. If not we are not able to determine the exact cap you need so we are not able to help, sorry. Often the part number can be on the inside of the cap and eBay is a good place to hunt some down.

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.

A shock absorbing wheel has its limitations. For starters, special rims would have to pair with these spoke-shocks. Plus, the high cost of shock absorbers suggests this wheelset would be extremely expensive, and the weight of the wheel would, presumably, be much heavier than traditional wheels.

The spokes on a standard spoked wheel hold it in tension. If the spokes lose tension, they start to break and the rim will buckle. A Loopwheel is not held in tension by its springs therefore the rim is strong, double-walled, and less likely to suffer from buckling or fracture at the rim.

Both modeling and experimental results demonstrate several realistic scenarios in which wheel hubs experience accelerations greater than 100g, sometimes at very low vehicle speeds. This paper focuses on the experimental determination of suitable design goals for in-hub motors (wheel motors), describing the experimental test rig, experiment procedures, and experimental results from testing conducted at UT-CEM. The paper also discusses implications of these results on wheel motor design, leading to the conclusion that a realizable and feasible design goal for a combat vehicle wheel motor shock rating is 150 g's, with a 10 to 20 ms pulse width.

This causes the hub to momentarily dip down within the wheel by up to 45 millimeters, so it’s actually a bit off-center until the springs flex back into their regular state. For this reason, the wheels will only work on bikes that already have sufficient space between the fork/frame and the tire – otherwise the bike would be hitting its own tires when the springs compressed.

We put up with a lot from our pneumatic tires, from punctures and blowouts, to slashings and the certainty of relatively frequent, inconvenient replacements and giant piles of waste rubber. The current technology seems well overdue for a revolutionary overhaul, if you'll pardon the pun, and yet despite dozens of fascinating attempts to reinvent the wheel, nothing seems to have found traction yet. Boy, I'm on a roll here.

I used to think that URT suspension and suspended seatposts were the worst ways to implement suspension on a bicycle. gringo on April 15th, 2013 - 3:10am
The gantry was to work by building a framework, with rails constructed from 1x1 blocks. The gantry X/Y axis arms are to traverse the rails with wheels. There would then be some pistons for the z axis, a rotor, and finally a landing gear for grabbing. All pretty straightforward stuff. On something like this, you do not want suspension on the wheels:

You’ll notice your loopwheel has more movement, vertically and laterally. As soon as the springs are loaded, they compress and further change their concentricity. This is what gives your wheelchair comfort and shock absorption. A Loopwheel is designed to absorb shocks, reduce jolting and cushion your body against vibration. You’ll notice more sideways movement than with a spoked wheel, but you’re trading rigidity for greater comfort.

@ Reason: We will update the pricing which we took from a catalog in 2009. The price advantage is still significant, if it was only because of changing over a consumable into a capital asset that can be amortized. Besides, only the treads need to be replaced at a fraction of the cost of a rubber tire. Investment, yes, value for money, certainly.

It’s a good idea to schedule regular inspections of your steering and suspension systems. It is usually easier, cheaper and safer to discover and fix a problem before it snowballs, causing further consequences.
I might eventually drop it. You have remember though, the roadsters sit atleast a half inch lower than the coupes to begin with (stock). Here's mine on 19's. I'll probably cut down the spring seats to level it up a bit in the rear. Use a slightly taller tire. That helps alot. Mine are 275/35/19 and 285/35/19 and I love the way it looks on the stock suspension. Last edited by Firehawk; 02-26-2007 at 03:34 AM. with my roadster, i went from Eibach, to Hotchkis, and now waiting for Tein Htech to come in. I think Htech will be the perfect drop for me, LOL Even with 35 sidewall tires, the gap in stock suspension is horrible. There are a lot of good points that have been made in this thread. I think a big factor in your decision will be really the road conditions in your area. Lots of changes in slopes that cause you to bottom out would not be a good thing for a lowered vehicle. The cars I have seen here look quite good, mostly because they have either 19s or dubs on them.
This design takes suspension to the next level and could benefit mountain bikers who want a cushier ride. Or more attention.

My background in wheel performance is its circular motion( which involves the circular of the wheel, and that the hub remains in the center of the wheel) if u are rolling with an oblong wheel, then u may actually exert more effort in lifting your self with the bike rather than rolling.
"If I had a preference," says Ina Ames, owner of Rim and Wheel Works in Waltham, "I'd avoid anything with a wheel diameter larger than 18 inches. Once you hit 18 inches, straightening becomes much more difficult. In the Greater Boston area, if you're driving cars with 19- or 20-inch wheels, you're just begging to come into my shop."

So how does it work? Well, a suspension fork (spoke suspension) only works on one plane. The Loopwheels on the other hand, provide what Loopwheels call, “tangential suspension.” Basically, they work in every direction, according to Loopwheels.com. So, they respond “to a force hit head-on in the same way as they do to a force from above or below.” This gives riders a smooth ride, instead of the lumpy, vibrating ride they are used to.
