目前我国使用的大部分车轮是冷铸生铁轮、中碳铸钢轮、带轮箍的车轮和整体轧钢轮.冷铸生铁轮在使用中容易发生缺陷及事故,使用寿命约两年,它的优点是价格便宜.中碳铸钢轮使用时虽较安全,但寿命不长,一般在一年以内.带轮箍的车轮,轮箍为轧钢的,须由国外进口,价格高,增加车轮本身重量,机械加工量大,装配工艺复杂,这样无形中增加了车辆的制造成本,且 At present, most of the wheels used in our country are cold-cast pig iron wheels, medium-carbon cast steel wheels, wheels with wheels and whole steel rolling wheels, which are prone to defects and accidents during use and have a service life of about two years The advantage is the price is cheaper.Carbon steel wheel although the use of safe, but not long life, generally less than a year.With the wheel of the wheel, the wheel for rolling steel, to be imported from abroad, the price is high, increase the wheel itself Weight, large amount of machining, complex assembly process, so virtually increase the vehicle manufacturing costs, and
