A steerable truck apparatus for railroad cars for providing for the controlled and uniform yawing of the axles of the truck. The truck apparatus provides for a yawing response which is linear substantially throughout the range of movement of the axles. The truck is further configured with pivotably supported pedestals for equalized load distribution. An improved axle bearing construction accommodates pivoting of the axle ends. A damping apparatus provides stiffness in the steering response toward reducing hunting of the wheels during straight line travel.

In a railroad truck, a forced steering system is disclosed for achieving optimal or near optimal wheel set alignment on both straight and curved track sections. Over- and under-steer on curves is minimized and oscillations are minimized or eliminated for trucks transiting straight track sections. A rigid frame and a suspension arrangement, both of which may be used in cooperation with the forced steering system, are disclosed. The forced steering system directs a force, related to the relative orientation between the car body and the truck, to the wheel suspension system thereby altering the wheel set geometry in an optimal manner for both straight and curved track performance.

The truck apparatus provides for a yawing response which is linear substantially throughout the range of movement of the axles. The truck is further configured with pivotably supported pedestals for equalized load distribution. An improved axle bearing construction accommodates pivoting of at least one of the axle ends. A damping apparatus provides stiffness in the steering response toward reducing hunting of the wheels during straight line travel.

A rail vehicle with two sideframes and a bolster as the freight car truck has limits on stability. A railway freight car truck having a friction shoe with a constant force device acting directly on the shoe flat surface is provided, such that the friction shoe is forced to remain in contact with the side frame mating vertical surface. The control spring acting on the friction shoe which applies a varying force to the side frame mating surface. The damping of the friction shoe is retained when there is less variable force of friction, which decreases vertical acceleration of the rail vehicle, providing high speed stability for most track conditions.

The traditional three piece railway freight truck prevents the wheel sets from achieving radial alignment to curves by the rigid side frames restraining the wheelsets. The side frames also constrain the wheelset from radial aligning to curves by the limited gap between the wheelset bearing and the side frame pedestal jaws.The present invention opens the side frame pedestal jaws to allow the wheel sets to yaw and align radially to curves. The side frame is supported on wheel sets by elastomeric pads and bearing adapters. The present invention utilizes the elastomeric pad stiffness to compress in pitch motion that allow the wheel set to move in an arc forward or backward in the open jaws of the side frame. The elastomeric pad stiffness also allows the wheelset to twist the pads allowing the wheelset to radially align to the curve. The pads elastic stiffness is sufficient to return when the wheelset is align to straight track.

A stabilized railway car truck consists of two side frames and a bolster. The bolster has laterally opposite ends, each end extending into and supported within a side frame opening on a spring group. The stabilized railway car truck also includes a transom extending into supporting contact with each sideframe by a hinge assembly. The spring group is supported at each transom end. The hinge assembly includes a pin arrangement that allows one sideframe to move vertically with respect to the other sideframe.

A three piece railway freight truck is comprised of two laterally spaced side frames between which a bolster extends. Suspension load springs support the bolster, and control springs support friction shoes.Both variations of friction shoes have gaps that will allow lateral movement of the friction shoe across bolster or the friction shoes across the side frame. The lateral movement is accomplished by having a low friction material pad between the bolster and friction shoe or a low friction material pad between the friction shoe and wear plate that bears on the side frame. The low friction material low siding resistance allows lateral displacement energy to be dissipated over the lateral decoupling clearance.

The present invention relates generally to a linear steering truck apparatus comprising a bolster member having two ends, the bolster being located along the transverse axis extending generally perpendicular to the longitudinal axis, generally located between and parallel to the transversely extending axles, a linear steering truck attachable to the car body, a plurality of pedestals, a pedestal engaged to an axle bearing, the axle bearing being rotationally engaged to one end of a transversely extending axle, and at least one pedestal being movably attached to at least one other pedestal situated in the same plane along the longitudinal axis, and rack and pinion steering components, where the geometry of pivot points from one axle to the bolster form a trapezoid and the geometry of pivot points from another axle to the bolster form a parallelogram, the pedestals being pivotably connected so that a lateral force at one axle is reacted by the other axle, wherein the car body mass acts as a pendulum mass restoring force, and the apparatus being steered to the center of the track with either end of the truck leading after the trapezoid side yaws.
