spoke

A spoke is a spoke plate on a car wheel hub, which serves as an independent device to protect the wheel rim and spokes of the vehicle. According to the structure of the spokes, wheels can be divided into spoke plate and spoke type, among which the mainstream family sedans use spoke plate spoke structure. The spoke plate is composed of a pair of circular cover plates, whose diameter is close to that of the wheel rim, and there is a hole in the center that is larger than the axis of rotation of the wheel. There are many holes near the edge of the cover plate, and there is also a circular wheel plate at the edge. The curved surface of the wheel plate can closely fit the curved surface of the wheel rim. This structure not only fixes the wheel rim and hub, but also serves to protect the wheel rim and spokes. ‌

The wheel rim is a circle that fits the tire, while the wheel hub is the part where the hub brake is installed (brakes are divided into disc brakes and drum brakes, and the hub brake cooperates with the wheel hub to achieve braking). The wheel rim is the component that installs and supports the tire, while the spokes are the supporting components located between the wheel axle and the wheel rim. A wheel typically consists of two main components: a rim and spokes. In some cases, the wheels also include the hub. ‌

The spoke type spokes are composed of steel bars, similar to the steel bars on bicycle wheels, used to connect the flower drum and the rim, playing a role in connecting the flower drum and the rim. Good spokes are relatively light and can withstand high strength. They can tighten the flower drum and wheel rim, making the wheels more round and not deform under external impact. High end road bikes often have flat or tapered spokes to reduce wind resistance when the wheels rotate
