Abstract A railway vehicle two-axle truck in which separate longitudinally extending side frames are supported at their ends on the axles, each side frame being formed at its center with transversely extending horizontal web structure wider than the side frame, a transverse transom resiliently connected at its ends to each transverse web structure at points spaced apart transversely of the truck, a transverse bolster pivotally related to the transom at the center of the truck and supported on the side frames by resilient side bearings, upright springs at the ends of the bolster for supporting a vehicle body, and means for transmitting tractive and braking forces from the bolster to the vehicle body. The last named means preferably comprises longitudinally extending improved bolster anchor links each connected at one end to an end of the bolster and at the other end to the vehicle body.
An anchor link adapted to connect a pair of parallel platelike members formed with aligned holes comprising a rod passing through said holes and hAving enlarged threaded end portions of substantially less diameter than said holes projecting outwardly from said platelike members and a reduced diameter central portion, assemblies slidably mounted on the projecting end portions and comprising a washer with an inwardly directed tubular extension of sufficient diameter to receive said enlarged end portions of said rod, said tubular extensions projecting inwardly through said platelike members, elastomeric annular pads surrounding said tubular extensions on both sides of both said platelike members, a spacer sleeve surrounding said rod between said platelike members and having end portions slidably mounted on the inner ends of said tubular extensions, washerlike flanges on said spacer sleeve ends, and securing means on the enlarged ends of said rod and movable lengthwise thereof in engagement with said washers for compressing said elastomeric pads between said washers, said platelike members and said sleeve flanges.
