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.
Among the very few prominent recumbent groups around the world precious few can boast of the long history of racing and designing bents as can the British Human Power Club. We’ll chat with club officers Alan Goodman, Barney Harle and Chris Hamilton about their full racing seasons (including the World HPV Championships), member’s unusual HPV builds and the early group history with founding member Dave Larrington. Also Dave Ashenbrener returns with an update on his “Lost Recumbent” AR-3 tilting trike which he has now produced and is available to purchase. Honza, Doug and Nina are back with their segments as well. Midwest Trike Demo Sale – February 27! Posted on February 26, 2021 by Larry Varney

In 2013 we raised funding to get loopwheels into production by running a Kickstarter campaign. 178 lovely people pledged their support; some are listed here.
Loopwheels are designed, engineered and made in Nottinghamshire by Jelly Products Ltd. It’s a registered design with patents pending. The story of loopwheels is one of determination, and a streak of madness. They were invented and developed by Sam Pearce, in his home in Nottinghamshire, England. By training and profession, Sam is a mechanical engineer and industrial designer. By nature, he is some one who loves making things: designing, building, doing. He loves simplicity, and products that work well. Sam is practical and hands-on. He is stubborn and doesn’t give up easily. All useful traits when you find you’ve set out on a journey to reinvent the wheel.

These air shocks are tuneable to give you whatever level of tire deflection you choose, from super-firm to softer and squishier than a regular deflated tire can handle. Likewise, you can design in whatever degree of lateral flex suits your application, and even whatever level of torque flex you'd like, which allows the wheel to flex a little on the axle before it turns. This allows it to act as a soft torque coupler and gives a touch more traction in very difficult circumstances before the wheel spins, as well as slightly isolating the drive train from damaging torque forces in the rough stuff.

Don’t blink. With eight extra inches of overall width, massive 35-inch tires and a menacing stance, TRX asserts itself as the most muscular truck to ever leave our factory.
Loopwheels are designed with suspension within the wheel itself: in place of rigid spokes, they have three loop-shaped springs.
Is there something I'm not getting? Is there a way to just slap a wheel on a block and have it roll, or are suspension blocks the only way? Without suspension blocks, wheels on a grid don't even show up in said grid's control panel or hotbar assignment menu. I even made a few test girds that were just carts with wheels directly on blocks, with thrusters for motive power; The wheels wouldn't even spin.
Technical ArticlesRear Wheel Drive Suspension OverviewRear Wheel Drive Suspension Overview Cameron from IPD goes thru the suspension components of rear wheel drive model Volvos and explains the basic setup and identifies the primary parts. "All right Cameron from here and today we're going to talk about some of the basics of suspension on a rear-wheel drive Volvo what the main components are where they are and what you should look out for. Here on the lift today we have a Volvo 242 so we'll talk about the main components on the front of it. First a lot of this is very much the same as you'll find on a Volvo 740 or a Volvo 940. As far as the front strut assemblies going and what the basic components are, even though they look a little different in those cars this should still give you a good idea of kind of where everything is and what it does. Looking also right here what you'll see is this, this is the sway bar end link bolts here to the control arm. This goes up and attach this to the sway bar right here which then goes across. Sway bars up you should be pretty familiar with on your car because it's IPD's flagship product and we've got huge upgrades for these that make the car handle ten times better and make it a whole new car. That's kind about it for the front it's a pretty basic suspension system there's just the control arm, ball joint, strut assembly, sway bar, and end link and the associated small pieces like control arm bushings that are here and here. Looking from the other side of the rear end of the car to show you some of the other components. We've just got a couple more pieces that complete the rear suspension system. This one is obviously the coil spring it is mounted on the back of the trailing arm here. If we follow that up we're going to see what is called the Panhard bar what its job basically is to locate the car over the rear axle. If you watch it here it bolts through the chassis of the car follow it down this way and it connects to a bracket on this side on the actual rear end. So, it's what is suspending it left to right and holding the car balancing it left to right over the rear end of the car. That's about it for the suspension very simple setup on these Volvo 740s and Volvo 940s are a little bit different but the basics are pretty much the same they use the same kind of components and hopefully, this helps you identify what's under your car you know what you're looking at any education is always going to help you maintain your car better.

"I have used my Loopwheels since they were first launched, I’ve tried them all, but NOTHING compares with these Loopwheels, after a month or so I had no more back pain, 75% less marks..."
Kerbs are less of an obstacle with loopwheels. Loopwheels reduce jolting, soften the impact of landing, and so can help manage pain. Over 95% of the customers rate Loopwheels as high or very high quality Over 85% of the users felt positive about Loopwheels after using them for 2 weeks Over 80% of our customers said they’d chosen Loopwheels to reduce the amount of vibration they experienced in their wheelchair
Much better to start with the wheelchair and bicycle markets, which are easier to break into. “Most of the world’s wheelchairs are used in hospitals, but there is a large premium market for people who want to live active lives but are restricted to wheelchairs by their disabilities. These people want to be as mobile and self-reliant as possible, and our technology makes this possible,” said Barel.
I don’t see how they could maintain torsional stiffness under braking… And that falls into the “bad” category. Mindless on April 15th, 2013 - 12:58am Gillis on April 15th, 2013 - 1:41am

The revolutionary Loopwheels have been specially designed to help wheelchair users get around more easily and with more comfort. The shock absorbing springs can give you extra power to get up kerbs and reduce jolting as you come down - for a smoother ride wherever you go.

In addition to their solutions for wheelchairs and (Yes!) cars, SoftWheel has three versions for bikes. The premium wheelset is the disc brake Fluent HD setup designed for all around and even off-road riding, and available with either 27.5 or 29″ carbon rims. Its 3 shocks use an adjustable preload gas spring and hydraulic damping for 40mm of shock stroke. That isn’t the same as wheel travel due to the orientation of the shocks, so it’s not exactly clear how that translates to rim movement or really hoe it would compare to traditional suspension travel.
First truck-only brand ever to win #1 in overall in initial quality according to J.D. Power.
But after a few rocky encounters, he decided there had to be a better way to maneuver over rough terrain in a wheelchair. So he did what anyone with experience in mechanics would do – he made a new wheel.
The fact that each shock is individually adjusted and tuned makes me wonder how difficult it would be to get them synced and the negative effects of them being out of whack with one another. Colin M on May 20th, 2016 - 10:53am nightfend on May 20th, 2016 - 10:59am
“First of all, it is symmetric to absorb shock in any direction," Rozanes told From the Grapevine. "Second, selective suspension means if you drive normally on flat surfaces, there’s no suspension unless encountering an obstacle."
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.
People have tried to make a wheel with suspension before but they have never had the right combination of design and materials. Hand Rim

Handling is similarly augmented. The e-tron’s center of gravity is already quite low thanks to the placement of the battery mass in the floor but tightening up the corners help keep it balanced.
Looks to me like it is a rigid rim and all the suspension takes place within the three loops of carbon inside. No worries about wheels changing shape or tires blowing off. The axle just moves off center during compression. ChrisC on April 14th, 2013 - 10:39pm ChrisC on April 14th, 2013 - 10:40pm jimmythefish on April 14th, 2013 - 11:00pm

Each wheel reportedly weighs about 300 grams (10.5 oz) more than a comparable spoked wheel.

The Acrobat doesn't exactly "reinvent the wheel," as the cliche goes, but it does improve upon it. Eliane Rozanes, one of the Acrobat’s engineers, said it has a built-in symmetrical and selective suspension system. In layman's terms, that means it takes the bumps so you don't have to.

His point was that the general consumer market is drawn to crossovers and SUVs, and not station wagons. Contrarily, Project e-tron is enthusiast owned… and Audi enthusiasts tend to prefer Avants. The low-slung long roof of the e-tron’s body makes for a quasi-Avant profile. While the general automotive buyer **may** disagree, we think there’s something to it. Audi’s considerable history of sporting longroofs gives considerable credibility and resonates with aficionados. For us, lowering Project e-tron was always part of the plan.
The wheel allows for vertical compression but provides rigidity in the lateral direction. The LoopWheel technology can also be used for wheelchairs providing comfort for the user.

Here are a couple of pics of my 2009 G37S with stock suspension and 20" wheels. I would love to lower the front some but I am fine with the back and I don't want to get into all the other issues that come up with lowering a car (rubbing, alignment issues, etc etc).
A vehicle’s suspension is a series of shock absorbing parts and springs that keep your car driving straight, and from bouncing too hard when riding over bumps. It also helps out with the braking process and keeps the body of your vehicle attached to the wheels.
The wheel fits to any bike with minor alterations. The added wheel suspension works with traditional fork suspension. Baigh explains his design in the video below. The LoopWheel is another design that features bow-spokes, only these are in elliptical shapes. The carbon composite springs isolate the rider from the high-frequency road noise preventing aches caused by jolting.
