自行车圈过去一向采用带钢加工制作的,近几年来由于自行车轻量化和美观等要求,已经逐渐采用具有轻而坚又易于加工的铝合金,经挤压加工成所需要的形状的型材来制造车圈,车圈是圆周速度较高的回转件,车圈如用铝合金来制造,势必大大提高自行车的加速性能和刹车的可靠性,并降低整车的重量,增进了美观. 目前铝合金车圈有焊接式和镶接式二种,镶接式车圈具有工艺简单,强度高,重
In the past, the bicycle ring has always been made of strip steel. In recent years, due to the requirements of light weight and beautiful appearance of the bicycle, the aluminum alloy which is light and easy to be processed has been gradually manufactured and extruded into the shape of the desired shape Rims and rims are rotating parts with high circumferential speeds. Rims made of aluminum alloy, for example, are bound to greatly improve the acceleration performance and brake reliability of the bicycle, reduce the weight of the vehicle and improve the appearance. Currently, the aluminum alloy There are two types of rims welding and mosaic type, mosaic rims with a simple process, high strength, heavy
