Abstract
A railroad passenger car suspension system in which a car body is supported on trucks in the running mode through rotary hydraulic actuators. All of the necessary conditions for passenger comfort, increased train speed and safety are met. The level of centrifugal force at curves is sensed and the car tilted so that the direction of force is felt by the passengers in a comfortable manner. Flush floor level of the car with station platforms, regardless of passenger load, wheel wear or platform level is attained. Lowered spring rate in the suspension system provides improved ride characteristics. Means are provided for steering the car trucks.
