Abstract: A railroad car truck for a railroad freight car, such as an autorack car, has a bolster mounted cross-wise between two sideframes. The bolster ends are mounted on respective spring groups carried by the sideframes. The bolster can translate laterally relative to the sideframes. The side frames are mounted to swing laterally relative to the wheel sets, and hence relative to the rails. Resistance to lateral deflection is provided by the resistance of the sideframes to the pendulum swinging motion, and by shear in the spring groups. The truck has a doubled damper arrangement of dampers in a four-cornered layout at each end of the bolster, giving a flexing resistance to yaw between the sideframes and the bolster ends. The doubled damper arrangement works against large wear plates mounted on the sideframe columns. The large wear plates are mounted normal to the dampers and square to the sideframes.

Abstract: The following disclosure relates to a rail car. In one embodiment, a railcar can comprise a span bolster, outer truck assemblies, and a middle truck assembly. The outer truck assemblies can be rotatably mounted to each end of the span bolster. The middle truck assembly can be slidably mounted at a middle portion of said span bolster. In another embodiment, a railcar system can comprise a pair of railcars and a body. The rail cars can comprise a span bolster, outer truck assemblies, and a middle truck assembly. The outer truck assemblies can be rotatably mounted to each end of the span bolster. The middle truck assembly can be slidably mounted at a middle portion of said span bolster. The body can have two ends, each of the ends connected to one of the span bolsters.

Abstract: A bogie (1) for a railway vehicle includes a motor (4) having a casing (6) fastened to two beams (2) of the bogie, the motor shaft (12) being arranged parallel to these beams (2), secondary suspensions (14) and a weight-bearing crosspiece (16) resting on the secondary suspensions (14). The bogie (1) includes a set of end supports (24) and stops (26) arranged on the casing (6) of the motor (4) and on the weight-bearing crosspiece (16).

Abstract: A process and a device for the control and/or regulation of a wagon body tilt system (1) for a railed vehicle, e.g., a train. Limit values with respect to comfort are taken into consideration for this purpose. In an equivalent way, these limit values preset a comfort scale for a rail camber or tilt (.phi..sub.c) as desired tilt values (.phi..sub.desired, .phi..sub.des. Speed, .phi..sub.des. accel.) for the control and/or regulation of a wagon body (2) as relevant value based on the system limits and permit a subsequent regulation within the adjustment system (4) of the wagon body (2) only within these limits. If at least one limit value for comfort and/or parameters describing the system is exceeded, these desired tilt values (.phi..sub.desired, .phi..sub.des. speed, .phi..sub.des. accel.) are then adapted by taking into account this at least one exceeded limit value and are converted to adapted desired tilt values (.phi.'.sub.desired, .phi.'.sub.des. speed, .phi.'.sub.des. accel.

Abstract: A two-axled central support bogie for railway and tramway vehicles with two or more articulated bodies includes two cross members carrying the wheels, and a central longitudinal structure the ends of which bear on two air springs carried by respective central platforms formed by the cross members. The central structure carries means for its articulated connection with the articulation ends of the vehicle bodies, and the bogie also includes tie means for connecting the central structure with one of the cross members to prevent movements in a longitudinal direction and lateral resistance means for limiting movement in a transverse direction.

Abstract: A railway vehicle, in particular a locomotive, has three or more trucks with the bolsters of each swivelly supported on the respective truck frames and having means for transmitting longitudinal traction and braking forces to the body underframe. The truck bolsters mount upright body-support spring devices which are yieldable in shear transversely of the locomotive to permit sufficient limited lateral movement of the body with respect to the trucks to prevent the full force of lateral blows and shocks received by the wheels from being communicated to the body and for preventing the momentum of the body from acting with its full lateral force on the truck wheels and rails.

Abstract: A vehicle tilt control apparatus has an acceleration detector for detecting vibration in horizontal and lateral direction of a car body, a fluidically operating mechanism disposed between the car body and a truck and compensation circuits for compensating a centrifugal force component and a jolting component, respectively, of the output of the acceleration detector. The outputs of the compensation circuits are added and the resulting output is fed back to actuate a servo valve to control the fluidically operating mechanism. In this manner, the riding comfort to the passengers when the vehicle passes through a curved area and for the jolting is improved.

Abstract: A safety device for a banking vehicle includes a pair of cylinders which extend to hold the superstructure in an upright position. The cylinders are hydraulically connected to an accumulator which provides a pressurized fluid reservoir. A valve controls flow from the accumulator to the cylinders. Upon detection of a failure in one of the vehicle systems the valve moves to a position in which fluid flows from the accumulator to extend the cylinders. A pilot operated check valve is positioned between the accumulator and the cylinders to hold the cylinders in the extended position until the failure is rectified.

Abstract: A truck for the pivotal support of two car bodies, particularly of articulated rail motor cars, comprises a truck frame having a vertical pivot for each car mounted in spaced longitudinal locations on the truck frame. A transversely extending swiveling bolster is centrally mounted for pivoting movement on each vertical pivot and each bolster includes a spring support adjacent each respective end for resiliently supporting the associated car body. The truck also carries slide means, such as interengaged slide plates on the truck and the bolster underlying the spring supports for slidably supporting the respective ends of the bolster on the truck.

Abstract: A vehicle has a wheeled chassis and a body movably mounted thereon, the body being able to carry goods and/or passengers. An accelerometer detects forces acting on the vehicle as the vehicle passes through a curve and is arranged to activate a vehicle body tilting and lateral displacing system. A first power mechanism tilts the body relative to the chassis toward the center of the curve. A second power mechanism laterally shifts the body relative to the chasis by applying lateral forces that are independent of the tilting forces. The lateral movement can be either toward or away from the center of the curve.
