Try to imagine the street without the usual clatter of wheels passing hundreds of cars. The wheel… what’s special about it? Meanwhile, in its long history has not written the last page. The wheel is one of the earliest inventions of man — as old as the author of it is unknown. Archaeologists have recently established that wheeled vehicles, the wreckage of which was found during excavations near the village of Bekovo in Bulgaria, around 5850 years! For a long time, while the person harnessed in such carriages of animals, the design of the chassis is almost remained unchanged. Decorated with carvings and gold, the wheels of war chariots of Ancient Rome were basically the same as that of the carts of our century: a wooden ring, tied with an iron Hoop, with wooden spokes in the center of a wooden plate with a hole for the axis. However, already in the XVIII century in expensive carriages occasionally could be seen and metal wheels… But those look like wood. Over time four wheel masters began to wear flat rubber ring — bus.

What happens if you cut a cylinder and two parallel planes at an angle to its axis and to replace the resulting “pancakes” wheels of a conventional car? It turns out that in the end we will get the vehicle of the increased passability. On normal roads this car moves exactly the same as a car with standard wheels, because at any point, the distance from the road to the axis remains constant, equal to the radius of the cylinder. Of course, with the difference that leaving a trail is not straight, but curved in the form of a sine wave.
