tire's modern version made by Goodyear's named by 'Spring Tire'

Goodyear said that this tire could be applied in the earth but it has no plans in that direction. And Spring Tire is not the only tech tire without air target mission to the moon. Wheel-based Lunar Tweel from Michelin is also being evaluated by NASA for missions to the moon in the future.

SOME years ago, the U.S. space agency NASA began work on a project together with the development of new Goodyear tires. the modern tire's version is named by 'Spring Tire'.

This tire is made of the load bearing spring 800 mounted on the shaft of six metal bars. The springs can be adapted to the varied terrain on the planet so it can roll without making the vehicle shakes excessively.

Because the strands of springs are able to adjust to the contours permukaanjalan and return to forms after the first pass. Goodyear also claims that the Spring Tire
with NASA's creation does not generate heat like other tires when operated.

Tires are made of 800 load bearing springs are designed to carry vehicles with a weight 10 times more weight with durability 100 times the distance that can be achieved that the wire mesh used tires by Goodyear when developing Apollo lunar roving vehicle cruising Vehicle (LRV).

Tire development is based on the fact that ordinary pneumatic rubber tires are not suitable for the lunar surface. Tire rubber has properties very susceptible to temperature extremes. While on the moon, among the areas hit by the sunlight does not have a super extreme temperature differences.

Direct radiation of sunlight is also made of rubber strength rapidly shrinking. Not to mention that the tire has lost air pressure alias deflated. Though there will certainly not be found plumbers tires. Adding a spare tire is also not a wise decision because it will only add to the burden of the charge.

"We needed to make fundamental changes in the tire that will explore the lunar surface, with a combination of an increase in the ability to load and service life," said Vivake Asnani, principal investigator for the project Researh Center NASA Glenn in Cleveland.

"What was developed by the Goodyear-NASA team is a simple network of interwoven springs are arranged in such a way that can serve as a substitute bankaret. Design of the tire itself refers to previous experience."

Spring Tire itself was mounted on the Lunar Electric Rover test vehicle in the past year carried out in 'Rock Yard' at NASA's Johnson Space Center in Houston. Goodyear claims that the tire spring field test was successfully passed.

"Tires are very powerful and highly energy efficient," explains Jim Benzing as the head of Goodyear's innovation projects. "The design of the contour of the spring against the surface to create good traction. And all the energy used to change the shape of the tire will be returned when the spring back into shape. Process does not generate heat in the tires as usual," he added.

When comes to the crunch, the conventional tire will leak, while the Spring Tire only cause damage to one part of the 800 load bearing springs so the tires can still be used normally.

In addition, continued Asnani, Spring Tire has a combination of rigidity and flexibility that allows off-road vehicle running quickly over a rough surface with a relatively small shocks because the tire is able to follow the contours of the road and absorb shock better than conventional tires.

Phibian, High Speed Amphibian, can go on the highway

Michigan, - Phibian has a ground clearance of 353 mm and both wheels, both front and rear, moving to follow the contour of the road surface bending. To get to the front cambernya 30 degrees, while the back 28 degrees. This design also enabled him to go on the battlefields of extreme alacrity and stir so that given the type code of "High Speed Amphibian".

military institutions as much as possible to have the vehicle ready on all fronts. Once on land, sea, and air, the combination was needed such as a vehicle for water and land. This is where Gibbs Technologies to create a vehicle that can go in two worlds.

His name, who claimed Phibian can go on the highway because of the speed regulations on eligible highway. Meanwhile, the speed of the water reaching 48.2 miles per hour. This is not a great number indeed, but rather for a transport vehicle that can carry 15 people (3 crew and 12 passengers) or a maximum weight of 1.5 tonnes.

The use of diesel engines is a twin turbo to go on land, while at sea using a twin jet, with total power 500 HP (combined). When running from the ground and into the water, Phibian took 10 seconds to change its function. Only a short time to fold all four wheels are sized 275/80R20 upon entering the water.

With the long dimension of 9212 mm width x 2532 mm x 3654 mm high and weighs 4.5 tons empty, Phibian motion system equipped with a multi-front-back option or select FWD, RWD and 4WD and hydraulic brake system and wheel type hydraulic power-assisted.

Sport Utility Truck's implied on SsangYoung Korando Sports

SEOUL - Safety of passengers is more prioritized through the installation of seat ISOFIX for passengers, and feature ESP (Electronic Stability Program), including a variety of functions such as Active Rollover protection and Antilock Brake System (ABS).

South Korean car manufacturers SsangYoung, last year launched the concept of a four-door pickup variant in the event the Geneva Motor Show, in March 2011 then.

Now, officially launched variant SsangYoung official production version SsangYoung SUT-1 "Sport Utility Truck '. The car was named SsangYoung Korando Sports. And his plan, it will immediately slide SsangYoung in South Korean automotive market.

SsangYoung Korando capitalize Sport 2.0-liter diesel engine capable of producing 155 horsepower and 360 Nm of torque at engine speed between 1,500 rpm and 2,800 rpm.

With the performance of the machine, combined with six percepatab 4WD transmission, all wheel drive. Capacity is already making this SsangYoung into a vehicle that has attracted performance.

Sport SsangYoung Korando uses an ultra rigid steel material as the body frame construction. Meanwhile, on the security features already equipped with dual airbags in the front seat and seatbelt pretensioners with load limiters.
