Wheelo is a detail that allows the body to be put on it, roll over, not glide. You can say that the wheel is the great-parent of a modern car.
In due course, the wheel has allowed a person to move faster than legs and to move goods that a person cannot lift alone.
Wheel appeared in 2001. At least, the Australian Patent Office, which gave a patent to a Melbourne patent to a "round device intended for the transportation of goods"
The New Wheel Story
The history of the wheel counts for so many thousands of years, which is lost in the depths of the ages. The most ancient clay wheels discovered by archaeologists are dating from the 5th millennium BC. The history of the car wheel, compared to the other mechanisms in its structure, is simple. At first it was no different from its predecessor, the cart for the cart-and was completely fulfilled from the tree. But the increasing loads and speeds have led to the first appearance of the metal rim and then the spokes. The wheels of early cars are like modern bicycle wheels.
The raw material used for the first cameras was the use of animal insides
The wheel rim first fitted with a rubber band, which was subsequently replaced by a pneumatic tyre. The transition to tires, which occurred at the turn of the 19th and 20th centuries, happened thanks to the invention made by veterinarian John Boyd Dunlop (Dunlop). Wishing to give a gift to his son, he made an inflatable camera for the wheels of his bicycle. As raw materials for the first cameras, John Dunlop used the material that was available to him because of his profession-the intestines of the animals. Dunlop's invention made a real revolution in the automotive industry, as it allowed the car to be truly comfortable. Soon, the short-lived tyres were replaced by rubber tyres, and their use was incorporated into the non-revocable standards.
In the 1920's, the wheels of the spokes were driven out by steel plates. The point is that the spokes, first of all, required constant suspension, and secondly, they stopped loading the loads at high speeds. In addition, the steel disks were significantly cheaper in production. Later there was another disc, which is familiar to modern motorists-a light-alloy aluminum disk.
The first mover in this direction was the company Bugatti with its Type 35 (1924). More recently, magnesium alloys, as well as composite materials (in the 1970s, Citroon produced a car with carbon fibre reinforced wheels). Many, but not Michelin developers, have forgotten about the spokes. The wheel of history may well turn back-by 2015, the "Mishlenovans" announced the emergence of a next-generation tyre called Tweel-polyurethane with a wedge, which is essentially a wheel disc and a tyre in one set.
What is a tire?
The correct composition of the wheel is: drive, rim, and tyre. On most modern passenger cars, the disc and the rim have been performed by a single unit, which is commonly referred to as a "disk" in the motorist environment.
- Stammed steel. For more than 90 years, it is the main type of automotive disc. Heavy, durable and inexpensive.
- Lite light-alloy. usually made of aluminium or magnesium alloys. They are worth more than steel, but lighter, and many different design options. The main disadvantage is fragility.
- Cowan light-alloy. More light and durable discs than lite but very expensive in production. But the great strength and rigidity of the forged disks has a negative effect-when they move on roughness, they do not mitigate the impact, passing all the load on the suspension of the vehicle.
- Composite. Non-metallic materials such as carbon fibre are used in the manufacture of such wheels. As a result of high cost, only expensive sports cars are used.
Wheels shall be different and fastening to the hub. The most common use of multi-point fixing on bolts or studs is used. But it's in regular cars. Let' s say for the Formula One cars, the wheel fixation on a few bolts is a luxury. Therefore, the wheel is kept on one nut and replaced within a few seconds.
It's not that simple with the wheel.
To invent the wheel is the favourite task of many engineers and enthusiasts. Many people, for example, do not rest in a circular shape of the wheel, come up with alternative designs-elliptic and even square wheels.
The square wheel was patented in 1959
The square wheel was even patented in 1959. The famous television show "Mythbusters" in 2012 decided to test the quality of the square wheels by installing them on a Ford F-Series pickup truck. It turned out that it was quite possible to ride them-at speeds above 30 mph, even shaking was almost felt. But efficiency was lower than the round, on any road-with deep mud, for example, there was no expected improvement of permeability.
Another attempt to improve the wheel was made by the American designer Charlie Paott. He decided to "cross" a flat tire and a human leg. As a result, the dynamic form of the wheel has changed.
Michelin engineers have developed an ActiveWheel electromechanical wheel, which can replace a number of elements of the suspension
This wheel is like a cut cake. When the straight line is round, but in turn, 8 pieces of segments are started to move, as if tilting the wheel and shifting the centre of gravity of the vehicle towards the turn. System developers claim that this is the kind of principle that humans use when turning.
Developers of Michelin Company went even further. They have provided the prototype wheels of the new generation ActiveWheel with electric motors, disc brakes and shock elements. One such wheel can replace a large number of units and units of a modern car.
