Reducing the weight of the vehicle body is an effective way to improve vehicle performance and reduce vehicle energy consumption.hubWeight is an effective way to reduce vehicle weight. Many existing car manufacturers have replaced cast iron wheels with lighter aluminum alloys to reduce weight. Next, I will introduce two-piece lightweightCar wheels.
The two-piece lightweight automobile hub includes integrally cast spokes and a rim, the spokes include a plurality of spokes arranged in a radial shape, the rim includes a rim body and rims arranged on both sides of the rim body, and the raised rim, spokes, and hub The connection and the rim body have the same wall thickness.
A connecting shaft is inserted between the two rims, and the two rims are fixed by the nuts on both sides of the connecting shaft, which increases the reliability of the hub. Since the connection between the spoke and the rim is the same as the wall thickness of the rim main body, the joint between the spoke and the rim The wall thickness is reduced, the weight of the wheel hub is reduced, and the lightweight design of the automotive wheel hub is realized, thereby prolonging the service life of the wheel hub.
The utility model has a simple structure, not only improves the performance of the car, but also saves the energy consumption of the car, conforms to the development trend of low carbon and environmental protection, and the equal wall thickness design effectively eliminates casting defects caused by different thicknesses in the casting process.
