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.

Is this trike perfect? Is this the trike you should get? Let’s get one thing straight right now: nothing is perfect, no trike is the one that everyone should buy – but let’s see if the TerraTrike Rambler is a trike you should buy. I always suggest that those interested find their closest dealer that handles the trike or bike involved, and check it out for yourself. I picked this one up at a new (to me) bike shop in the southeastern corner of Cincinnati, Fifty West Cycling – https://www.fiftywestcycling.com/ – nice place!

NOTE: Catrike lead time is now 27 weeks. You must order, with 50% down payment, any Catrike model you want by March 15 in order to have one by early Fall 2021. No order, no Catrike in 2021. We don’t like this one bit but we have no choice – 7 month back order time will put us out of business unless we have co-commitment for each Catrike ordered.

Loopwheels have developed a robust wheel with world-class suspension that works at higher speeds, for use with power attachments. The springs utilise hi-tech carbon composite materials and are available in 2 spring strengths (Regular and Stiff), which will allow customers to get the best comfort and health protection for their weight and the typical activities that they undertake. Weighing under 3lbs (1.36kg) per wheel, and removing much more vibration than any other brand of a wheel, it is the definitive wheel if you love travelling faster on tracks and off-road. Made in England Loopwheels are vibration reducing wheels. Integral suspension gives you a smoother ride.
We’re growing rapidly now. We’ve got good distributors in important export markets. We plan to expand into our current market and to look at taking our technology into other areas. This could be for use in other vehicles including for lightweight electric vehicles in our congested cities.

Curve & Curve L are a high quality, ergonomic push rim designed and made in Germany. These are available in two sizes: ‘Curve L’ for a larger hand, or ‘Curve’ for smaller hands. Designed for wheelchair users with complete hand function.

To ensure that its product lived up to user standards, Softwheel turned to Dror Cohen, who became a paraplegic after a car accident in 1992. Cohen eventually became a decorated athlete, leading Israel to the gold medal in sailing (sonar class) in the 2004 Paralympics in Athens, Greece.
The spring configuration allows the torque to be transferred smoothly between the hub and the rim

A set of ASW wheels, on the other hand, will cost you more upfront but last something like 13 times longer – out to the service life of the truck itself. Your first set of six wheels in this case will run you about $1.705 million, but over 10 years you'll likely only need two tread replacements at around $55,000 a pop, giving you a 10-year budget of $1.815 million and a $845,000 saving.
Previously on bespoken we’ve featured articles on manual and motorised chairs which help the user negotiate uneven streets and rougher pathway, but a lot of them have been both expensive and a bit impractical for day-to-day use. A new Kickstarter, Loopwheels, addresses this problem with a simple and far more affordable design. Loopwheels contain integral suspension meaning the wheels absorb more shock than a standard wheel and allow the user to negotiate tougher terrains with greater ease and comfort. The Kickstarter also says that they can be fitted onto most standard wheelchairs. Following up from a successful campaign to raise funds for the Loopwheel as a bike wheel, this latest project has already raised over half of its £16,000 goal with 28 days left to go.
The Loopwheels will go on sale in September for £600, and their inventor claims they can make riding on a bumpy road 'like riding on velvet' 44 year old Nottingham mechanical engineer Sam Pearce told MailOnline he came up with idea while watching a mother try and push a child in a buggy up a kerb.
Also, look around for any other gear you might need for the coming season of riding.

Innovative design means the wheel has a stiff structure but an element of compression. The springs within the wheel are made of a carbon composite material.
Loopwheels are an innovative approach to wheelchair suspension and shock absorption.
And it's not like I have some high dollar customer sport chair, either. I use a "Breezy". Street price of $575. About as cheap as you an go. (https://www.quickie-wheelchairs.com/Breezy-Wheelchairs/Breezy-Lightweight-Wheelchairs/Breezy-600-Lightweight-Wheelchair/2403p) And the only modification I made was to cut grooves into the solid rubber tires.

Double wishbones are used mostly at the front. There are two wishbones, one above the other, to keep the wheel upright as it rises and falls.

The Global Air Cylinder Wheels team has also sent us a bunch of video detailing the advantages of a much smaller scale ASW for wheelchairs. Because of the built-in suspension effect, you'd likely experience more ride comfort, as well as a vastly superior ability to negotiate uneven ground without any of the wheels lifting off and losing stability.

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.

It is a significant risk factor for those with spinal disorders, increasing the amount of muscle fatigue and potentially damaging connecting nerves. Vibration is also believed to have significant impact on pain, the development of pressure sores, spasticity and general discomfort. It limits the time, distance and surfaces that users will consider for manual chair use.

Leaf springs are likely to wear because they have several moving parts. They should be inspected at intervals specified by the car manufacturer, or at major service intervals - usually every 12,000 miles (20,000 km). Facebook @howacarworks Twitter @howacarworks YouTube @howacarworks
