About the structural components of the wheel

The wheel is a rigid wheel that fixes the inner edge of the tire, supports the tire and bears the load together with the tire, and is mainly composed of the hub, rim and spokes. The hub connects the wheel and the axle, and is responsible for the power transmission between the tire and the axle; the rim is the part of the wheel that installs and fixes the tire; the spokes support the connection between the hub and the rim. Wheels can be divided into spoked wheels and spoke wheels according to the different spoke structures, among which the spoked wheels are most widely used, with the advantages of light weight and high dimensional accuracy, which can significantly improve the wheel's aerodynamic characteristics and reduce fuel consumption. It can significantly improve the aerodynamic characteristics of wheels and reduce the fuel consumption of automobiles.

Tire is a circular ring-shaped rubber product mounted on the car or machinery, the main functions include supporting the body, cushioning the external impact, to achieve contact with the road surface and to ensure the driving performance of the vehicle. The structural composition of the tire includes the inner liner (innerliner), cord fabric ply, bead, sidewall, carcass skeleton ply and crown belt ply. According to the different structure, tires can be divided into bias wire tires and radial tires, modern vehicles basically use radial tires.

The combination of wheels and tires is known as a wheel assembly, and together they bear the loads that enable the vehicle to operate. The use of wheels has contributed to technological progress and social change, especially in transportation and warfare. The invention of the wheel has had a profound impact on the development of human civilization by enabling people to move objects much heavier than themselves quickly.
