Different types of wheels include spoked wheels, solid wheels, and alloy wheels. Spoked wheels are commonly found on bicycles and motorcycles, providing strength while reducing weight. Solid wheels are often used in industrial applications due to their durability, while alloy wheels, made from a mixture of metals, are popular in automobiles for their aesthetic appeal and performance benefits. Additionally, there are specialized wheels like caster wheels, racing wheels, and off-road wheels, each designed for specific uses.
The most common types of wheels and axles used in bike trailer construction are spoked wheels with quick-release axles, solid wheels with bolt-on axles, and pneumatic wheels with axle nuts.
An alloy wheel starts life as a huge chunk of metal, which is then machined until you have a hub area, a rim area and then a thin section tying them all together. A spoked wheel starts out with a hub, a rim, a pile of spokes and a handful of nipples. The rim is then connected to the hub by attaching one end of each spoke to the hub and the other to the rim. When they're all tightened up and adjusted properly you get a round and true whee.
The first axled wheel carts used solid wood wheels with a square box on top. Spoked wheels became widely used for transportation (wagons and carts) but solid wheels were sturdier for wheelbarrows and are still used today.
