Tube Rims

　　The rim, commonly known as the wheel hub, is an intermediate part that fixes the tire and connects the tire to the axle. After continuous improvement, under the conditions of modern industrial technology, the wheel hub has become a fully functional integral component. It is responsible for carrying the weight of the vehicle, transmitting power, supporting the tires and other functions, and as a rotating moving part, the hub must meet the technical conditions of light weight, fatigue resistance, and dynamic balance under the premise that the wheel has a certain rigidity. Compared with the previous steel wheels, the weight of aluminum alloy wheels is greatly reduced: under the same size and same strength, the quality of aluminum alloy wheels is about half of that of steel wheels. Lightweight aluminum alloy wheels can make the vehicle performance better, and at the same time make the vehicle fuel-efficient and good heat dissipation.
