Nitinol chain tires are woven with nitinol wire to provide better traction performance in extremely cold climates. Nitinol alloy has super elasticity and memory effect. Compared with traditional rubber tires, the advantages of chain tires are that they have better nitrogen filling rate, adhesion, durability and performance stability. Moreover, in areas where driving is difficult, such as heavy snow and ice, chain tires can provide stronger support for the vehicle while also meeting people's requirements for driving safety.
Glenn Research Center scientists turned typically elastic aerodynamic materials into memory alloys that can withstand significant reversible strain. This allows superelastic tires to withstand more deformation than any other non-pneumatic tire while enabling enhanced control, increased Designed for versatility, the tires can be used on a wide range of space vehicles or vehicles on Earth.
"For example, superelastic tires can soften by increasing deflection, thereby reducing the amount of energy transferred to the vehicle during high-speed operation on rough road sections," commented NASA Glenn Research Center. Initially, NASA's Glenn Research Center worked with tire manufacturer Goodyear to develop a primitive version of the spring tire. It weaves spiral steel wire into a mesh pattern to form a hollow tire shape. However, the tire deformed when tested on a Mars-like surface. Later, NASA engineers thought of using a shape memory alloy nickel-titanium instead to solve the deformation problem.
NASA plans to launch the next Mars rover in 2020, and the tires developed will not only be applied to Mars missions, it can also replace traditional pneumatic tires on Earth and bring innovation to the off-road field.
The design of the chain tires we use Nitinol Superelastic wire looks very shocking from the outside. Its links are so strong that they can even compete with steel. These chain links are properly spaced, pinned to each other and twisted together to form a solid chain network, which can effectively alleviate the impact of the wheel when driving and provide a more stable passage for the wheel. Observed from the side, these links appear to be full of dynamic energy, rather than some static device. It is precisely because of the kink and friction between the chain rings that chain-type tires can provide unparalleled performance under extreme conditions.
In short, the production of chain tires uses an innovative new material - Nitinol wire, which not only solves some problems of traditional tires, but also provides people with a new driving experience. Its importance cannot be underestimated as it has become a trend and has brought confidence and benefits to those looking to try something innovative.
