Overview Of Karaoke On 4 Wheels
The first evidence of carts, wheel, cars or their models, there is from the second half of 4th millennium BC. BC. Between northern Germany and Mesopotamia, z. B. In Northern Europe under the Funnel Beaker Culture and the Baden culture, in foothills of Alps in northwest and the Southern Caucasus (Maikop culture), in Mesopotamia and the Indus Valley Civilization (Karaoke on 4 Wheels).
As the material only wood was used for thousands of years. The first spoke wheel had bronze spoke, later in Bronze Age and then outweighed wooden spoke wheel only involving the rubbing on the inner surface of axle hub and the outer race of rim with metal was misty. Advances in metallurgy towards ever more stable metals found then also use.
During the Bronze Age, the wheel was known to his present form of disc - the lighter spoked - further developed. The spokes form was created by removal of unnecessary for the function of wheel portions of wheel between the hub and the outer rim. To simple machine elements counts usually not rolling, but only the spinning wheel (for example wheel, steering wheel). A vehicle is now called the complex technical component or complex machine element.
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.
