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.

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.

Have you ever had an oversized truck pass you and your vehicle sways from side to side? This is a sign of worn or weak shocks and struts. Weak, worn, or bad shocks and struts can cause very poor vehicle handling issues and ride comfort problems. This is because worn shocks and struts have lost the internal pressure and ability to keep applied pressure downward. This can cause excessive bounce and roll when hitting bumps or potholes, which can also lead to premature tire wear.
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.

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.
There are two basic types of vehicle suspensions: independent and solid axel. The main difference between these two is that both right and left wheels attached to the same beam i.e. solid axle, while independent suspensions make provision for one wheel to go up or down without affecting the other wheel.

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.

A pair of shock-absorbing wheels for wheelchairs with integral suspension, designed to help you push over uneven streets, rough tracks, grass and gravel paths, with less effort. The carbon leaf springs give you extra power to get up or down kerbs/curbs. They’re wonderfully comfortable over cobblestones, and potholes needn’t be a problem any more!
In the end, their method worked. Project e-tron now sits about 30mm lower than it did when it was delivered at the dealership. Effectively, every setting in the range is now 30mm lower, with the allroad setting being roughly equivalent to the previous comfort setting.
Design concern: Compressing the suspension changes the center of the wheel. When the wheel is also rolling this means there needs to be a ‘handoff’ between the three struts. The result will be the translation of energy in to compressing the next strut which will slow the wheel. Torquemada on May 21st, 2016 - 9:39am

I bought a pair of loop wheels a couple a years ago, unless they have improved, i found they bend from side to side. After spending a lot of money on them, i returned to my spocked wheels. So far there is nothing to beat the spocked tried and most successful design. the best suspension i found is seat post suspension and front faulk suspension.
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.

Basically, the steering system allows the driver to guide the vehicle. The steering wheel is connected, via the steering column and a series of pivoted joints, to the suspension system. This allows the wheels to move up and down as required by the road surface without changing the steering angle. This system also ensures that the wheels turn as required, for example the inner front wheel (which has a tighter curve than the outer one) is more sharply angled when cornering. Like the suspension system, the steering system also requires precise adjustment, as any looseness in the joints can make the steering dangerous.
When driven wheels are independently suspended, the differential is fixed to the frame and drives the wheels by jointed drive shafts.
The Loopwheels’ spring system between the hub and the rim cushions the rider from potholes and bumps in the road. It also reduces road noise by absorbing it, thereby reducing vibration through the frame—and into the rider’s arms and body. Because the suspension is inside the wheel, you don’t need fat tires to make the ride nicer. Instead, you can use high-pressure or puncture-resistant tires.

With boulders in your sights, TRX shifts to an extra low gear ratio and uses a 50/50 torque split. Plus, a Selec-Speed® Control holds a set velocity for a controlled descent.
The wheelchair application seems to run straight into the eternal problem with sprung wheels. Without dampers, they bounce badly, as sometimes seen in tractors fitted with buckets on a bad road. With dampers, they have very high rolling resistance. I tire needs enough flex to meet the ground, but any further suspension should be on the axle. Lardo January 30, 2018 06:00 PM
