Abstract

An elastomeric pad placed in shear and having one portion or surface engaged with a portion of a railway car body and another portion or surface engaged by pivotal linkage means to a wheel housing dampens vibrations of a wheel and axle assembly which is resiliently mounted to the car body for rollingly supporting the car body. The pivotal linkage is elongated and connected to the wheel housing and the car body using spherical bearings to minimize wear. The linkage is attached at an angle of inclination to minimize strain on the elastomeric pad and linkage assembly caused by vertical travel of the railway car body due to varying weight loads.
