The original type of spoked wheel with wooden spokes was used for horse-drawn carriages and wagons. In early motor cars, wooden spoked wheels of the artillery type were normally used. In a simple wooden wheel, a load on the hub causes the wheel rim to flatten slightly against the ground as the lowermost wooden spoke shortens and compresses.
The artillery wheel was a nineteenth-century and early-twentieth-century style of wagon, gun carriage, and automobile wheel. Rather than having its spokes mortised into a wooden nave (hub), it has them fitted together in a keystone fashion with miter joints, bolted into a two-piece metal nave.
Parts of a wheel. The basic parts of a wooden wheel are nave (or hub), spokes, felloes (felly) and tyre (tire). [3] [4] The nave is the central block of the wheel. In a wooden-spoked wheel, the nave acts as the hub. One end of each spoke is set into the nave in a process called tennoning. In older wheels, the nave had a 6-inch sleeve that fit ...
The earliest known examples of wooden spoked wheels are in the context of the Sintashta culture, dating to c. 2000 BCE (Krivoye Lake). Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater part of three centuries.
The rim is the "outer edge of a wheel, holding the tire". [1] It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles. [2] For example, on a bicycle wheel the rim is a large hoop attached to the outer ends of the spokes of the wheel that holds the tire and tube. [3]
The Ljubljana Marshes Wheel is a wooden wheel that was found in the Ljubljana Marsh some 20 kilometres (12 mi) south of Ljubljana, the capital of Slovenia, in 2002. [1] Radiocarbon dating , performed in the VERA laboratory ( Vienna Environmental Research Accelerator ) in Vienna , showed that it was approximately 5,100 to 5,350 years old, which ...
Using a 100-long-ton (100 t) vertical press, load testing was conducted of the strength and elasticity of the SCOA-P wheel centre against a 2,021 lb (917 kg) conventional spoked driving wheel centre of an A2 class locomotive that had the same diameter, but was engineered for a lower 17.5-long-ton (17.8 t) axle load). The tests revealed that the ...
Usually, a small wagon contains 9, 12, or 16 bolts. The back axle usually contains 4 bolts, and the front varies among the different steering designs. The wheels can be air tires, hard rubber tires, or hard plastic tires. Some small kids' wagons are made completely out of plastic. Some are made of wood, aluminum, poly, or steel.
