Tweel
The Tweel (a portmanteau of ''tire'' and ''wheel'') is an airless tire design developed by the French tire company Michelin. Its significant advantage over pneumatic tires is that the Tweel does not use a bladder full of compressed air, and therefore cannot burst, leak pressure, or become flat. Instead, the Tweel's hub is connected to the rim via flexible polyurethane spokes which fulfil the shock-absorbing role provided by the compressed air in a traditional tire. Design The Tweel consists of a band of conventional tire rubber with molded tread, a shear beam just below the tread that creates a compliant contact patch, a series of energy-absorbing polyurethane spokes, and an integral inner hub structure. Both the shear beam and the polyurethane spokes can be designed to provide a calibrated directional stiffness in order to control both how the Tweel handles and how it handles loads. The inner hub structure may be either rigid or compliant, depending on the application requi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airless Tire
Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. They can be used on small vehicles such as ride-on lawn mowers and golf cart, motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high. Tires composed of closed-cell polyurethane foam are also made for bicycles and wheelchairs. Advantages & disadvantages The main advantages of airless tires is that they do not go flat and need to be replaced less frequently. Heavy equipment outfitted with airless tires will be able to carry more weight and engage in more rugged activities. Airless tires generally have higher rolling resistance and provide somewhat less suspension than similarly shaped and sized Tire, pneumatic tires. Other problems for airless heavy equipment tires include dissipating the heat buildup that occurs when they are driven. Airless tires are often filled with compressed polymers (plastic) ra ...

Run-flat Tire
A run-flat tire is a pneumatic vehicle tire designed to resist the effects of deflation when punctured, allowing the vehicle to continue to be driven at reduced speeds for limited distances. First developed by tire manufacturer Michelin in the 1930s, run-flat tires were introduced to the public market in the 1980s. They have increased in popularity over time. Technologies There are three basic technologies currently available, described below. Self-supporting The origins of the commercial ''self-supporting'' run-flat tire started in 1935 with a tire that had a fabric inner tire. The tire was advertised as a protection against blowouts, a common and dangerous occurrence in the 1930s. In 1934, Michelin introduced a tire that was based on technology developed for local commuter trains and trolleys. It had a safety rim inside the tire which if punctured would run on a special foam lining. The tire was sold for military use and for specialized vehicles like bank armoured cars. It was ...

Segway
A Segway is a two-wheeled, self-balancing personal transporter device invented by Dean Kamen. The name is a registered trademark of Segway Inc. It was brought to market in 2001 as the Segway HT, and then subsequently as the Segway PT. ''HT'' is an initialism for "human transporter" and ''PT'' for "personal transporter." Ninebot, a Beijing-based transportation robotics startup rival, acquired Segway Inc. in April 2015, broadening the company to include other transportation devices. In June 2020, it was announced that it would no longer make the Segway PT. History Independent company The Segway PT, referred to during development and initial marketing as the Segway HT, was developed from the self-balancing iBOT wheelchair which was initially developed at University of Plymouth, in conjunction with BAE Systems and Sumitomo Precision Products. The first patent of human transporter was filed in 1994 and granted in 1997, followed by others, including one submitted in June 1999 ...
