A wheel is a disc-shaped object with ideally circular contour, which is mounted rotatably about its axis of symmetry and is most commonly used as a wagon wheel. This invention and use of carts or wagons was an important for the development of technical culture in prehistoric event. Is an essential advantage unrolling its circumference on the ground. Sliding takes place only in lubricated bearings (Karaoke on 4 Wheels).
The oldest evidence Eastern Georgia in Caucasus was 2012 in Lagodekhi, excavated to a 4,000 year old Kurgan containing two 2-axis four-wheeled cart with small rather primitive pulley wheel. This vehicle was drawn not from domesticated horses, but probably of cattle, such as the excavator of Georgian National Museum suspected.
Probably this Kurgan belongs to a leader of last phase of Kura Araxa culture that has clear links to Maikop culture. More detailed investigations are pending. The car recalls in construction of representation of a troop transport on the Standard of Ur. In grave were not only the obsidian and flint and amber beads. This supports the hypothesis that the car came long before the horse from the northern area and with the spread of Kura Araxa culture took the road to south. This oldest Radfunde are either assigned to burials in graves cart or bog finds from wetlands. The dates of sites currently allow no decision on a place of origin of bicycle and car technology. A more recent attempt pleads for. Example of a Central European car invention.
The design of wheel was always (later paths and roads) matched to surface to be traversed, and improves the surface corresponding to increased requirements. Steel frost on wooden rim wheel for wheelbarrows, two- or four-wheeled wagons, carts or carriages on farmland, field or boardwalks or cobbled streets or the first commercially operated electric tram in FOTG on rails.
The edge of tread was chamfered or rounded. Some faces were so well preserved that smoothing strokes of a tool can be seen. The wheel created from alder wood belonged to a car whose front could not swing. When changing the direction the draft animals dragged the front of car to side until the drawbar pointed in desired direction.
In loop but some of load and the design weight to carry, they had an advantage over other means of transport a good off-road capability. When using a sledge and rod loops usually a high sliding resistance was overcome. A transport rollers was possible only on well prepared surface and short distances.
Proved rolling transport from the Bronze Age Egypt. The disadvantage was that the wheel all the way designed or repeatedly taken back and had to be placed in front of object to be transported over again. But you could move relatively heavy loads, as they are spread over a larger area than it is in bearings of wheel later.
Metal spokes were until the 19th century again a leader, be it due to higher loads and speeds, such as rail transport, it was after the invention of spokes fall made it possible to build very light sturdy wheel with thin taut wire spokes as they especially when today bicycle are common.
