First wheel
The first wheel dates from 5350-5100 years ago, discovered at a Ljbljana site (Slovenia) in a swampy area. It is said that it could have arisen thanks to the observation of placing cylindrical logs under the load to be moved and adding axles. -
3500 B.C. POTTER WHEEL
It is about providing centrifugal force to a mass of mud placed in the center of the disc-wheel, using human or electric traction. The pella (pug) must be well centered on said wheel and needs to rotate at a minimum of one hundred revolutions per minute to begin to "ascend" and acquire the shape that, pressed with his fingers, the potter creates. In short, the objective is to direct the energy received by the mud with the turning of the wheel with your hands. -
2000 B.C. WOODEN WHEEL
The oldest known archaeological remains were found in Ljubljana, the capital of Slovenia. It was found along with its axis; It measures 72 cm in diameter and is made of ash wood, while the axle, which rotated along with the wheels, was made of oak, harder. But they began to be introduced 1700 B.C. -
1550 B.C. BRASS WHEEL
Bronze wheels were first built by the Egyptians in 2000 B.C. and were built for chariots of war. They had 4 spokes made entirely of bronze and were very similar to the wheels of the most recent European cars. -
1500 AD WHEELS WITH GEARS
From the year 1500, gears were introduced to the wheels to facilitate transportation in vehicles. The gears are formed by two toothed wheels, of which the largest is called the crown and the smallest pinion. A gear is used to transmit circular motion through the contact of toothed wheels. One of the most important applications of gears is the transmission of movement from the shaft of a power source -
XIX CENTURY PNEUMATIC WHEEL
The wheel takes thousands of years of use, but the idea of putting rubber on the outer rim is relatively new. It was in the early 19th century that natural rubber was first used to coat wooden or steel wheels. Now, as the rubber was wearing out quickly, his future did not look very promising. The first pneumatic, or air-filled, rim was patented in 1845 by Scottish engineer Robert W. Thomson. -
20th CENTURY WHEELS WITH ALLOY WHEELS
The first tires began to be manufactured in the 20th century and were built with iron, steel, rubber or rubber rings, more or less wide and thick, which were externally adjusted to the wheels of civil and military cars or carriages and they served both for a longer life of the wheel, and not to spoil much the way of circulation.
