Loopwheel springs are made from a carbon composite material, carefully developed and tested to give optimum compression and lateral stability as well as strength and durability. Specially-designed connectors attach the springs to the hub and rim. The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain – cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel. The spring configuration allows the torque to be transferred smoothly between the hub and the rim.

Founder Sam Pearce describes his design idea: “In 2007 my idea of a wheel with tangential suspension was born when I was sitting at Eindhoven airport waiting for a flight. I saw a mother pushing her child in a buggy. The front wheels hit a slight kerb and the child jolted forward because of the impact. I asked myself why a wheel couldn’t have suspension inside it, so it would soften an impact from any direction. I sketched the idea in my notebook, got on my flight, and didn’t think much more about it for a couple of years.”

Ditto for cars, said Barel, although implementing the SoftWheel system in planes and cars won’t happen overnight. “Plane designs have to be approved by the Federal Aviation Industry in the US, and implementing changes in the automobile industry takes time. But eventually, both industries are going to adopt our design. Until now you had to choose between comfort and efficiency in wheel design, and now, for the first time, you can have both.”

Loopwheels reduce the level of vibration—“road noise”—through the chair frame and up into the arms, wrists and shoulders.
“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."

Please take the time to register and you will gain a lot of great new features including; the ability to participate in discussions, network with other RV owners, see fewer ads, upload photographs, create an RV blog, send private messages and so much, much more! Personally I don't like to lift wheels off the ground with the jacks and I would never lift the drives off the ground. If it's so unlevel that the wheels would be off the ground, I'll run up on some boards first to get close, then finish leveling with the jacks. Fronts are ok. You won’t damage anything. As stated above, never the rears (drive wheels) because the parking brakes are on the rears. If you’re not comfortable with the fronts being off the ground, you can build some small ramps or wood blocks you can drive the front wheels onto. If you search for ramps on this forum you’ll find lots of examples. When an air bag RV is lifted, ONLY the axle weight is left on the ground. no matter the lift height. This is unlike a leaf or coil spring vehicle. The tires provide limited stopping. If the leveler pads are on softer ground, they will put much restriction to the RV moving sideways as the pads will be in a hole. The suspension system has no problem handing from the shocks / limit straps. It endures FAR greater stress while you are driving down the road soaking up the bumps and road heaves. All that being said, try to NOT lift the RV any further up than is required. Things inevitably break. Hydraulic lines, solenoids, seals etc. You don't want a single leg to drop on it's own which the torques the chassis. An RV up in the air is invitation to crawl underneath or store stuff under. Not good when something breaks. So, pick a more level spot or use blocks to get the rig as level as you can before lifting. Don't park on a hill and lift so that there is no chance of slipping sideways (tire and / or leveling pad friction). Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times... I don't like to lift either off the ground ever. I only use the jacks enough to level the final little bit and to not have the coach shake while moving around in it. The thread Sonic posted is great! I use 2x10s like suggested in the posted link, but took it slightly further. I didn't cut an angle, don't really need it and in the past I found that it sometimes gives them the ability to slip while driving onto them. I would post pictures but it is in the shop for engine repair and the boards are in unit. Basically I took 2x10s and cut 2 boards the longest that would fit in the bay I was storing them in (about 36 inches long). I then cut 3 more boards about 8 inches shorter (for a total of 4 boards high), so lenghts of, 12, 20, 28, 36 long. I have 2 sets in case there is a need for the rear duals to go on boards. To keep the boards from sliding when driving onto them, I bought 3 different size carriage bolts that would go through 2, 3, or 4 boards but not all the way through, just long enough to keep them stable as you drive. I then took a spade bit that was 1/8 inch larger than the bolts and drilled through all 4 boards to accommodate the bolts, i did this in the rear where they would line up even and no worry about puncturing tires if they popped up slightly. I then took a spade bit slightly larger than the bolt head, and drilled on top of the holes the thickness of the bolt head. This way they sit down flush with the boards. It works very well! For the jack pads, I couldn't use anything very thick, as if I am on level ground and I dump the air, I only have about 4 inches between the jack pad and ground. I took 2x4s, and cut them the length of 3 2x4s put next to each other. I cut 6 in total. I then laid them crossways (think the first 2 layers of Jenga) and nailed them together from both sides. These work great for leveling! When i get it back from the shop next week I will try to remember to post some pictures. Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times...

    Loopwheels are designed with suspension within the wheel itself: in place of rigid spokes, they have three loop-shaped springs.

    SoftWheel also claims that this movement measurably decrease the energy lost from suspension movement. Their simulated track testing equated these gains to 16.4% extra energy that was not lost in a traditional suspension system. That of course means saving energy for the rider, and results in faster rolling. We’ve seen conceptually similar solutions like the carbon leaf Loop Wheels without damping, and even a smaller amount of suspension built into Gokiso’s hubs, but these Fluent wheels are certainly more tech-heavy.
