We’re proud to be a British manufacturer of a world-class innovation in wheel technology.
The University of Texas at Austin Center for Electromechanics (UT-CEM) has conducted a set of simulations and full-scale experiments to determine suitable shock load design requirements for in-hub (wheel) propulsion motors for hybrid and all-electric combat vehicles. The characterization of these design parameters is required due to recent advancements in suspension technology that have made it feasible to greatly increase the tempo of battle. These suspension technologies allow vehicles to traverse off-road terrains with large rms values at greater speeds. As a result, design improvements for survivability of in-hub motors must be considered. Defining the design requirements for the improved survivability of in-hub motors is the driving factor for this research.

Hi we are new to a air ride equipped motorhome and are wandering if it is ok to lift the wheels off the ground with the Jack's when leveling on those unlevel sites, the chassis is a Freightliner XC and it seems like the air bags are really stretched if the wheells and everything are pulling down on them in this situation ... We just do not want any damage to the system. Your input would be appreciated thanks The weight of the axle pulls down on the air bags but the weight of the front axle assembly is supported by the length of the shocks. When the shocks become fully extended, air bags, leaf or coil springs, that's when the front axle assembly quits moving down. I'm with everyone that doesn't like the looks of wheels in the air, but it doesn't hurt anything and I have done it. Think about this: The only way your motorcoach can roll away is if it's on the wheels. If it's up on the jacks, it can't roll. A good backhoe operator will hike the rear tires (where the brakes are) up in the air to get it up on the hydraulics where it is solid and stable, before operating. Sometimes they raise the front tires up with the bucket. Ever seen a mobile construction crane? First thing they do is raise all the tires up off the ground to get the unit level and stable before operating. I'm not saying to lift your coach that way, but it's not the big deal that some people try to make it sound like. On my Freightliner with the stiff rear end and V-Ride, if I lift one side a couple inches, the duals will come off the ground. Not a big deal because the jack won't roll.

Let’s put as much weight in the wheels as we can! I would just love to have to accelerate all of that weight over and over again in stop-and-go city traffic. Woof! Talk about energy savings!

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
Each time the wheel revolves, you’re compressing “suspension”. This means that precious rider energy is being wasted, constantly. It’s kind of like the drag you get from soft, 5″ fat tires.
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 you 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.
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.

The forces imposed on the anti-roll bar subject it to constant twisting and flexing, which in turn put its various rubber mounting bushes under great load. The bushes gradually wear and lose their effectiveness. Over a period of years the rubber hardens and tends to crack.
