Can you distinguish between rims, spokes, rims and hubs?

The wheel is an important part of the vehicle walking mechanism, which not only supports the weight of the whole vehicle, alleviates the impact of the road, but also generates driving force and braking force through the adhesion of the tire to the road surface to ensure the normal running of the vehicle.

The composition structure of the wheel mainly includes the rim, the spoke, the hub and the tire. Among them, the rim, the spoke and the hub sound like the same, so that many owners do not know, today we will talk about the difference between them.

1. Rim

The rim, also called the rim, refers to the parts around the wheel that mount and support the tire, which together with the spoke bear the wheel load and dissipate the heat generated by the tire.

The above is a common rim structure, strictly speaking, is a combination of the rim and the spoke, according to the different manufacturing materials, many owners directly called it "steel ring", "aluminum ring", referring to the rim made of steel and aluminum alloy.

2. Spoke

The spoke refers to the part of the wheel that connects the rim to the hub.

According to the structure of the spoke, the wheel can be divided into two types: spoke plate and spoke. Generally, long-term high-speed vehicles are mostly multi-spoke, which can provide good support and avoid or reduce the wheel deformation during the driving process; On the contrary, vehicles that pursue lightweight characteristics on short-distance technical runways are mostly low-spoke, with a unique sense of exposure in appearance.

Spokes and rims can be divided into integral, permanently attached and detachable.

3. Wheel hub

The hub, commonly known as the "gourd head", refers to the parts that connect the wheel and the axle, mainly through bolts or dowel connected to the rim and the axle, and also provides the central support for the wheel.

In many places, the hub and the rim are used to be confused, in fact, these are two parts, and the rim is the part that installs and supports the tire around the wheel. The wheel hub is a barrel-shaped metal part that supports the tire's inner rim and is centered on the shaft. The scientific name is called "wheel hub unit".
