buyAutoSock
The Tire Rack recommends that drivers who normally encounter recurrent snow and ice during wintertime fit their vehicles with dedicated winter tires. However there also are drivers in areas outside of America's snow belt where the roads are rarely, if ever covered with snow or ice. Unfortunately these drivers face very perplexing problems when a freak snow or ice storm catches them off guard! Additionally the growing use of summer tires for Original Equipment (O.E.) applications, as well as for upgrading replacement tires, has stranded more than one motorist caught by unexpected snow or ice.

Temporary Winter Traction Aid for Vehicles (Autosock product)
AutoSock is a proven temporary winter traction aid that is now available in America for a wide range of vehicles. Tests carried out by European car manufacturers and independent road and transport research institutes have confirmed that AutoSock increases traction on snow and ice substantially over summer tires.
Developed in Norway and TÜV-approved in Germany, AutoSock is lightweight and made from 100% high-technology fibers that stick to snow and ice. These fibers, which are intended to fray with use, are arranged in a specific pattern to optimize their grip. The specially developed textile also has the ability to process the water film often found between the tire and an icy or snowy road generated by heat from the sun, vehicle load or wheel spin.
Because vehicles need the ability to stop and turn as well as accelerate in slippery conditions, The Tire Rack recommends that AutoSock be installed in sets of four. AutoSock is sold in pairs to accommodate vehicles with staggered wheel and tire fitments (different sizes on their front and rear axles).

Comfortable While Driving – Maximum Speed 30 Miles per Hour (mph)
AutoSock does not produce the loud rattling nor the bumpy ride associated with snow chains. AutoSock does not damage the vehicle structure or alloy wheels and are approved for speeds up to 30 mph (50km/h). Nevertheless, the driver's speed should remain appropriate for the weather and road conditions.
In What Sort of Conditions Can AutoSocks Be Used?
AutoSock will greatly enhance traction on snowy or icy surfaces. It is recommended that AutoSock be removed when the vehicle returns to roads where no snow or ice is present. Driving on dry or wet roads is not recommended as it increases fabric wear considerably.
Simple to Install and Remove Even in Cold Weather
Stop the vehicle and apply the parking brake. The vehicle must not be on a slope during installation. The AutoSock is pulled over the top of the tire and downwards as far as possible. Then the vehicle is moved forward or backward about one yard, and the remainder is pulled into position. AutoSock will automatically center when driving begins. The same basic directions apply if the vehicle is already stuck, however only a small amount of wheel spin is used instead of moving the car in that case.
What About When AutoSocks are Removed from the Vehicle?
AutoSock is likely to be wet and probably dirty. They should be put back in their storage bag using the gloves provided. After reaching the destination, AutoSocks should be dried and the dirt shaken out, and can be machine washed. AutoSock is reusable, easy to store and should be put back in the vehicle for the next time a rare snow or ice storm arrives!
NOTE: AutoSock is not considered a traction device in severe snow conditions and cannot be substituted for chains for travel through mountain passes.

Unexpected winter weather can create driving conditions demanding more traction than conventional tires -- or even snow treads -- can provide. But tire chains are bulky to store and can be difficult to put on in cold, snowy weather. Now there is an easy-to-use alternative to chains: Designed in Norway, AutoSock is a new and innovative lightweight fabric-based, temporary traction aid for cars and trucks that is easy to mount and gets a grip on slippery surfaces as snow and ice. AutoSock, a high-technology textile tire covering, utilizes specially patterned fibers that optimize grip on slick surfaces by managing the thin layer of water on top of ice and snow. Through its weaving pattern and thousands of small fibers AutoSock clings to snow and ice, increasing vehicle traction, improving safety and adding to driver confidence.





With AutoSock, you won’t experience the rattles and bumpy ride associated with tire chains, and it is approved for speeds up to 30 mph. AutoSock is easy to install following these simple steps: Stop the vehicle and apply the emergency brake, fit AutoSock to the drive wheels of the vehicle, starting at the top of the tire and working downwards. Then, stretch the elastic band over the top of the tire to the inside of the tire, tighten the crossing strap, and move the vehicle approximately 3 feet and pull the remainder of the AutoSock into position. AutoSock automatically self-centers when you begin driving. When you’ re back on snow-free roads, slip the AutoSock off and slip it back into the included storage bag.






After use, AutoSock should be put back in the storage bag until the destination is reached. Then they can be machine-washed and put back in the bag, ready to go for the next snow or ice storm. Note: AutoSock is not meant for severe snow conditions, and cannot be substituted for chains for travel through mountain passes. The High Performance AutoSock accommodates performance tire sizes (typically OEM sizes for sports cars, SUVs, luxury cars, or +1/+2 wheel and tire aftermarket setups). It is also safe on aftermarket wheels and can be used with electronic traction control systems and ABS. For standard tires, use AutoSock Standard

Ditch Your Snow Chain And Put On Autosocks

There are always a few products at SEMA that lack glitz and glamour but are all about pure function; the AutoSock is one of these. Developed in Norway, the AutoSock is a great alternative to bulky snow chains and spiders. The AutoSock is made up of “high-technology” fibers. These fibers provide additional grip in snowy and icy conditions. The AutoSocks are simple to install. Simply slip them over the drive wheels as far as possible, then pull forward a tad and pull them over the rest of the wheels. The AutoSocks are self-centering and will even works with studded tires.According to their website, the AutoSocks are more effective than snow tires, and even more effective than chains in certain situations. But the big advantage of the Sock system is that they can be fitted to cars that have minimal clearance between the tire and wheel-well unlike snow chains. Because there are no straps, hooks or bolts holding them in place, they also work well with alloy wheels that could be damaged by spiders or chains. The AutoSocks are machine washable and come with their own carrying case to keep your trunk dry. Worried about durability? The AutoSock has passed the same durability and distance tests as snow chains.
The AutoSock is not available in the US as of yet, but look for it to be on the market in the not too distant future.

Friction development for Autosock

Links product as : http://astore.amazon.com/autosock-20


Friction
We developed the idea of making AutoSock out of a high-technology textile fabric with high friction propertiesaccording to new theories on the effect of electrostatic charging and pressures on friction.
Tribology/ Dry vs. wet friction
Tribology is defined as the science and technology of interacting surfaces in relative motionand of the practices related thereto.A tribological system consists of three parts:
Upper surface
Lubricant
Lower surface
In the case of friction on icy or snowy roads the upper surface is the tire or AutoSock, thelubricant is water film created by frictional melting and liquid layer on the ice/snow, and the lower surface is the icy or snowy road.
When the water film thickness is insignificant, we have dry friction; this is the case when brakinga car at -20ºC. When the water film separates the two surfaces, we have wet friction; this is thecase when a car water planes.
AutoSock wants to have as large an area as possibleunder the AutoSock with dry friction, since dry friction givesthe highest friction coefficient.
Snow vs. Ice friction







AutoSock has:
A surface pattern that makes the total contact area exposed to friction sufficiently large under both soft and hard snow or ice conditions
A combination of surface pattern, strength and elasticity that make the contact pointssufficiently sticky under hard snow or ice conditions To some extent we have a trade off between good friction properties on snow relative to ice. It is favourable to open up the structure in order to increase the total contact area exposed to friction on snow. At the same time the contact points need to be sufficiently sticky on hard ice. The contact configuration of a tire or AutoSock can be quite different on snow relative to ice.
The upper figures show the contact configurations of a tire on soft snow.
The figure to the left simulates compaction resistance, while the figure to the right simulates impact resistance.
The lower figure shows the contact configuration of a tire on ice where the macroscopic impact and compaction resistances are negligible.
Electrical parameters

The AutoSock is made of a special high friction textile fabric.In a frictional AutoSock sliding situation, electrostatic pressures can be defined in:
The air gaps between: a) the sock surface and the icy or snowy road, b) the sock surfaceand the water film, c) the water film and the icy or snowy road surface.
The interfacial contacts between: a) the sock surface and the icy or snowy road surface, b) the sock surface and the water film, c) the water film and the icy or snowy road surface.
The water film.
The dry friction process is dominated and characterised by accumulation of electrostatic chargesin the slider contact points. The frictional water film initiates discharge of potential differencesbetween the slider and the sliding surface due to the much higher electrical conductivity ofwater relative to snow/ice.
The topography of the slider and the sliding surface is decisive for the electrical contactconfiguration between the slider and the sliding surface.
The electrolytic conductivity of a melted snow/ice sample may indicate the rate of ions introducedto the interface between snow/ice and the slider by frictional melting and thereby the rate and ease of discharge between the slider and snow/ice through the frictional water film during braking. Larger frictional electrification should take place on snow/ice with low electrical conductivitycompared to snow/ice with high electrical conductivity.


Friction properties on ice and snow

AutoSock has been developed with good friction properties both on ice and snow. The AutoSock is characterised by:
A specially designed surface pattern that makes the total contact area exposed to dry friction as large as possible both under dry and wet snow or ice conditions.
Hairs between and at the contact areas in order to increase the total contact area exposed to friction.
A surface pattern that makes the total contact area exposed to friction sufficiently large under both soft and hard snow or ice conditions.
A combination of surface pattern, strength and elasticity that make the contact points sufficiently sticky under hard snow or ice conditions.
Development of friction materials

The storyWhen Henry Ford had problems getting his car going under ice/snowy conditions, his wifeused to put a carpet in front of the tire, and Henry got going. The idea behind the AutoSockhas been to use textile in a similar, but more efficient way. One day Bård Løtveit found out he should friction test his own cotton shirt, and the friction properties turned out to be surprisingly good.
Was it possible to learn something from the cotton shirt?
We put Bård’s cotton shirt under our laser microscope.
The image shows the cotton surface of Bård’s shirt viewed through our microscope. We can see that the contact areas of the cotton surface are small and dense and that the total contact area is relatively large. Hairs on the cotton surface increase the totally exposed contact area to friction.


This image shows a rubber summer tire. The rubber summer tire has a large total contact area and small flexible points.



The image shows a sock with poor friction properties on ice. The totally exposed contact area to friction is too small under hard snow or ice conditions.



From testing these, we developed the idea of making AutoSock out of a high-technologytextile fabric with high friction properties according to new theories on the effect of electrostaticcharging and pressures on friction.
First Generation AutoSock

The contact area of the first generation AutoSock in the image is larger and stickier than for the previous sock. The grooves and roughness given by the surface pattern exposes the sock to more snow under soft snow or ice conditions, and increases the totally exposed contact area to dry friction under wet snow or ice conditions. At the same time the totally exposed contact area to friction is larger under hard snow or ice conditions than the previous sock.The hairs between the contact points increase the totally exposed contact area under all snow and ice conditions.

Reserch and Developent for Autosock

Research and DevelopmentAutoSock AS has cooperated with leadingresearch institutes for the creation of theperfect AutoSock

Liks for products as: http://astore.amazon.com/autosock-20

AutoSock is working with leading research institutes to carry out measurements and testing of prototypes, with the aim of better understanding the combination of friction and winter conditions.
Extensive research has brought AutoSock through a series of stages - from the first simple sock with a short lifespan beneficial only for specific conditions, to a robust sock suitable for most conditions.
Subsequent tests had a focus on the following aims:
Improve ice friction without compromising the snow friction properties.
Make use of 'state of the art' knowledge about ski base sliding friction theory and ski base structures.
Exploit ways to objectively and scientifically describe the surface texture of different AutoSock prototypes in order to increase understanding about the prevailing friction.

The frictional surface of an AutoSock combines the following sets of characteristics:
A surface pattern with a sufficiently high degree of coarseness to make the total contact area exposed to dry friction as large as possible under dry, wet, hard and soft snow or icy conditions.
A combination of surface pattern, strength and elasticity that make the contact points sufficiently sticky under snow or icy conditions.
