在瑞典和其他西欧国家的铁路上使用的大部分货车都装用三种型式的走行部,即装有转向架构架弹簧悬挂装置的比较新型的Y25型转向架,或装有相当陈旧的、使用转向架构架弹簧悬挂装置的G型转向架,或者是在轮对轴箱上采用车架弹簧-拉杆式悬挂装置(在无转向架的两轴货车的情况下)。所有这些型式的走行部均由国际铁路联盟实现了标准化。此类货车的数量相当庞大,它们还将在相当长的时间内运行在各国的铁路线上。悬挂装置的拉杆系统可以保证货车在弯道上运行时有着良好的静态内接,但是其动态内接,特别是在高速运行时,并不令人满意。
Most of the trucks used on the railways in Sweden and other Western European countries are equipped with three versions of the runway, the relatively new Y25 bogie with the bogie frame spring suspension, or the rather old, steering-using Type G bogie with spring suspension, or with frame spring-rod suspension (in the case of a two-axle truck without bogie) on the wheel axle box. All these types of walkways are standardized by the International Union of Railways. The number of such trucks is quite large and they will also run on national rail lines for quite a long time. The tie rod system of the suspension device ensures that the truck has a good static internal connection when running on the curve, but its dynamic internal connection is unsatisfactory, especially at high speed.
