Inner Tube
An inner tube is an inflatable torus that forms the interior of some pneumatic tires. The tube is inflated through a valve stem and fits inside the tire casing. The inflated inner tube provides structural support and suspension, while the outer tire offers grip and protects the more fragile tube. Use Nowadays, most bicycle tires use inner tubes. They are also used in items such as dolly carts, wheelbarrows, and many motorcycles. In the past, car tires used inner tubes, but most cars now use tubeless tires that hold air without an inner tube. Tubeless tires offer advantages, as they can operate at both low and high pressures without the risk of pinching or bursting, unlike tube tires. Large inner tubes are used for various recreational activities, such as flotation devices in tubing. History Inner tubes were invented in the 1800s for use with pneumatic tires, as standard wheels at the time were not air-filled, making them uncomfortable to ride on. Over the years, inner ...

Torus
In geometry, a torus (: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanarity, coplanar with the circle. The main types of toruses include ring toruses, horn toruses, and spindle toruses. A ring torus is sometimes colloquially referred to as a donut or doughnut. If the axis of revolution does not touch the circle, the surface has a ring shape and is called a torus of revolution, also known as a ring torus. If the axis of revolution is tangent to the circle, the surface is a horn torus. If the axis of revolution passes twice through the circle, the surface is a Lemon (geometry), spindle torus (or ''self-crossing torus'' or ''self-intersecting torus''). If the axis of revolution passes through the center of the circle, the surface is a degenerate torus, a double-covered sphere. If the revolved curve is not a circle, the surface is called a ''toroid'', as in a square toroid. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumatic Tire
A tire (North American English) or tyre (Commonwealth English) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, tires were ...

Valve Stem
A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire), and is then automatically closed and kept sealed by the pressure in the chamber, or a spring (device), spring, or both, to prevent the gas from escaping. There are many types of valves, and they are most commonly used on Tire, automobile, Motorcycle tire, motorcycle, and bicycle tires, but also for many other applications. The most common type is the Schrader valve, but some road bicycles with skinny tires instead use the Presta valve. Schrader Schrader valves consist of a valve stem into which a poppet valve is threaded with a spring attached. They are used on virtually all automobile and motorbike tires and on wider-rimmed bicycle tires. In addition to tires, Schrader valves of varying diameters are used in refrigeration and Air conditioning, air conditioning systems, plumbing, Fuel injection, engine fuel injection, Car suspension, suspension systems, and SCUBA Divin ...

Bicycle
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered transport, human-powered or motorized bicycle, motor-assisted, bicycle pedal, pedal-driven, single-track vehicle, with two bicycle wheel, wheels attached to a bicycle frame, frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more than 1 billion bicycles. There are many more bicycles than cars. Bicycles are the principal Mode of transport, means of transport in many regions. They also provide a popular form of recreation, and have been adapted for use as Toy, children's toys. Bicycles are used for Physical fitness, fitness, Military bicycle, military and Police bicycle, police applications, Bicycle messenger, courier services, Cycle sport, bicycle racing, and artistic cycling.

Motorcycles
A motorcycle (motorbike, bike; uni (if one-wheeled); trike (if three-wheeled); quad (if four-wheeled)) is a lightweight private 1-to-2 passenger personal motor vehicle Steering, steered by a Motorcycle handlebar, handlebar from a saddle-style seat. Motorcycle designs vary greatly to suit a range of different purposes: Long-distance motorcycle riding, long-distance travel, Motorcycle commuting, commuting, cruising (driving), cruising, Motorcycle sport, sport (including Motorcycle racing, racing), and Off-roading, off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activities such as joining a motorcycle club and attending motorcycle rally, motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparable numerically t ...

Flotation Device
A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or tread water in order to stay afloat and can even be unconscious. PFDs are commonly worn on small watercraft or other locations where accidental entry into deep water may occur in order to provide immediate support for the wearer should they end up in the water. PFDs are also kept on large vessels for passengers to wear in an emergency in order to help them stay afloat should they be forced to enter the water or accidentally fall overboard during an evacuation. PFDs are commonly worn for swimming and other activities that require an individual to be in water. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubing (recreation)
Tubing, also known as inner tubing, bumper tubing, towed tubing, biscuiting (in New Zealand), or kite tubing, is a recreational activity where an individual rides on top of an inner tube, either on water, snow, or through the air. The tubes themselves are also known as "donuts" or "biscuits" due to their shape. Variations Water Tubing on water generally consists of two forms: towed and free-floating, also known as river tubing. There is also water skiing. According to ''Time Magazine'', tubing was purportedly invented on the Black River (Arkansas–Missouri), Black River in Missouri by Jan & Harriet Wright of Poplar Bluff, MO sometime in the middle of the 20th century, but examples of the practice were published as early as 1916, when the popularization of the automobile meant a large supply of rubber inner tubes was available to the general public. Towed tubing usually takes place on a large body of water such as a lake or river. One or more tube riders (often called "tuber ...

1930s Red Innertubes
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Tubeless Tire
A tubeless tire ( also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim. History Many patents had been filed covering tubeless tires. ''Killen Tire'' applied for a patent in 1928 and was granted in the UK in 1930. The Wingfoot Corporation, a subsidiary of Goodyear Tire were granted a patent in South Africa in 1944. Due to technical problems, most of these designs saw only limited production or were abandoned. Frank Herzegh working for BF Goodrich applied for a patent in 1946 and eventually received in 1952 in the United States. By 1955 tubeless tires became standard equipment on new cars. BF Goodrich had to defend their patent in court several times, due to the similarit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...
