    • A high speed powered railway bogie arrangement comprises a traction motor assembly mounted from the locomotive body so as to be isolated from, but to swivel with. the bogie. The motor drive shafts may be parallel to the axles of the bogie wheelsets. A flexible drive train accommodates relative motion between the traction motor assembly and the bogie wheelsets. A linkage between the bogie and the traction motor assembly allows for some degree of lost motion between swivelling of the bogie and swivelling of the traction motor assembly.
      By decoupling the mass of the traction motors from the bogie, "hunting" disturbances of the bogie, which tend to arise at high speeds, are minimised. A Watt linkage between the bogie and the locomotive body allows the bogie lateral freedom of movement with respect to the locomotive body.
    • 高速动力的铁路转向架装置包括从机车主体安装的牵引马达组件,以便与转向架隔离,但与转向架一起旋转。 马达驱动轴可以平行于转向架轮轴的轴。 柔性传动系适应牵引马达组件和转向架轮对之间的相对运动。 转向架和牵引电动机组件之间的连接允许在转向架的旋转和牵引电动机组件的旋转之间的某种程度上的运动。 通过将牵引电动机的质量与转向架分离,倾向于以高速度出现的转向架的“狩猎”干扰被最小化。 转向架与机车车身之间的瓦特连接允许转向架相对于机车车身的横向自由运动。

    • A frame (46) is disclosed for use with a railway truck (14). The frame may have a pivot housing (34), a first arm member (54) extending outward from the pivot housing and having opposing distal ends (42), and a second arm member substantially identical to the first arm member and extending outward from the pivot housing opposite the first arm member. Each of the first and second arm members may have a generally planar upper plate (56), a generally planar lower plate (58), and plurality of webs (60) vertically disposed between the generally planar upper and lower plates. An upper surface of the pivot housing may be generally co-planar with the generally planar upper plates of the first and second arm members.

    • There is provided a three-axle truck for a railcar (101) having three wheelsets in a truck frame (110) of the one truck, in which in each of the wheelsets, axle boxes (115) are supported by the truck frame through axle springs (116), the truck frame has a structure for supporting a carbody (180) whose weight is variable, and making variations in axle loads on the respective wheelsets be maintained at a preset value or less in spite of change of the carbody weight, and in this structure, spring constants of the both-end axle springs (116a, 116c) in the respective wheelsets (121, 123) located at both ends of three axles are set to be larger than a spring constant of the middle axle spring (116b) of the wheelset (122) located in the middle.
    • 在一个卡车的卡车框架(110)中,为具有三个轮对的轨道车(101)提供三轴卡车,其中在每个轮对中,轴箱(115)由卡车框架通过轴支撑 弹簧(116),卡车框架具有用于支撑重量可变的车体(180)的结构,并且尽管车身重量的变化,使得相应轮对上的车轴载荷的变化保持在预设值或更小, 并且在该结构中,位于三轴两端的各个轮对(121,123)中的两端轴弹簧(116a,116c)的弹簧常数被设定为大于中间轴弹簧的弹簧常数 116b)位于中间的轮对(122)。
