  • Leveling railway vehicle and related systems and methods
    Patent number: 9315203
    Abstract: Leveling railway vehicles, leveling secondary suspension systems, lift-systems for suspension systems, and other related systems and methods are shown and described. In one example, a railway vehicle includes a superstructure, a bogey, and a leveling secondary suspension system. The leveling suspension system includes at least one spring positioned between the superstructure and the bogey, and a secondary suspension-mounting lift system (SMLS) interfaced with coil spring. The SMLS includes a spring-mount (SM) and a piston assembly. In operation, pressurized hydraulic fluid acts on the piston and lifts the superstructure, thereby allowing the superstructure's access to be raised to a desired height, e.g. a platform height.
