The spoked wheel was invented to allow the construction of lighter and swifter vehicles. The earliest physical evidence for spoked wheels were found in the Sintashta culture, dating to c. 2000 BCE. [1] Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater
Wire wheels, wire-spoked wheels, tension-spoked wheels, or "suspension" wheels are wheels whose rims connect to their hubs by wire spokes. [ 1 ] [ 2 ] [ 3 ] Although these wires are considerably stiffer than a similar diameter wire rope , they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting ...
Three spoked wheels on an antique tricycle. The spoked wheel was in continued use without major modification until the 1870s, when wire-spoked wheels and pneumatic tires were invented. [46] Pneumatic tires can greatly reduce rolling resistance and improve comfort.
All wheels have four spokes. The "chariot" comprises the solar disk, the axle, and the wheels, and it is unclear whether the sun is depicted as the chariot or as the passenger. Nevertheless, the presence of a model of a horse-drawn vehicle on two spoked wheels in Northern Europe at such an early time is astonishing.
For his landing wheels, he shifted the spoke's forces from compression to tension by making them from tightly-stretched string, in effect "reinventing the wheel". [21] [22] Wire soon replaced the string in practical applications and over time the wire wheel came into common use on bicycles, cars, aeroplanes and many other vehicles.
The wheel was made of ash and oak and had a radius of 70 cm and the axle was 120 cm long and made of oak. [10] In China, the earliest evidence of spoked wheels comes from Qinghai in the form of two wheel hubs from a site dated between 2000 and 1500 BCE. [11]
The sāqiyah might, according to Ananda Coomaraswamy, have been invented in India, where the earliest reference to it is found in the Panchatantra (c. 3rd century BCE), where it was known as an araghaṭṭa; [21] which is a combination or the words ara (speedy or a spoked[wheel]) and ghaṭṭa "pot" [22] in Sanskrit.
Velocipedes (cycles) had wheels of increasingly disparate size, with the front growing ever larger than the rear. Notable were the high-wheelers, or penny-farthings, a version of which Starley made with William Hillman. Their Ariel vehicle was all-metal and had wire-spoked wheels, much lighter than wooden-spoke ones. Tangent spokes were ...
