摘要： A wheelset steering apparatus and method for the truck of railway vehicles, wherein an axle box rotatably provided on the opposite ends of the wheelset is elastically supported in the longitudinal direction as well as in the lateral direction of the truck with respect to a truck frame. Vertical loadings on the truck frame are carried by the axle box. A spring constant in the longitudinal direction of the truck in a state of being elastically supported with respect to the truck frame of the axle box is varied when the vehicle runs. The self-steering property of the wheelset is enhanced, and stability in running on a straight track is secured.

摘要： A vibration control apparatus for vehicles to be installed on the vehicle wherein a vehicle body is supported on a truck through springs and damping mechanisms, for suppressing the vibrations of the vehicle body and enhancing the riding quality of the vehicle, comprising a vibration detector which detects the vibration of the vehicle body, a compensator circuit which compensates the detection output of the vibration detector and produces a control output for suppressing the vibration of the vehicle body, a fluid operating mechanism which controls the relative displacement between the vehicle body and the truck and which is connected to the vehicle body on one side and to the truck on the other side, a fluid control device which controls the fluid operating mechanism by the use of the control output produced by the compensator circuit, and damping control means to suppress the damping function of the damping mechanism upon sensing the state under which the vibration of the vehicle body is suppressed by the fluid operating mechanism.
