Abstract

La presente invención se refiere a una unidad de cojinete lateral para usarse con un vagón de ferrocarril, comprendiendo dicha unidad de cojinete lateral; una tapa superior generalmente redonda, una superficie superior con una porción central plana y una porción lateral angular con ahusamiento con respecto a dicha porción plana central, una pared lateral formada integralmente dependiendo hacia abajo, una superficie de fondo con un tope sólido secundario dependiente situado centralmente y formado integralmente y una superficie de tope primario adyacente a dicha pared lateral; una caja que incluye, una porción de base preparada para acoplarse al vagón de ferrocarril, una pared lateral formada integralmente que se extiende hacia arriba con una porción primaria de tope para cooperar con la superficie primaria de tope adyacente a la pared lateral, un tope sólido secundario situado centralmente, formado integralmente que se extiende hacia arriba para cooperar con el tope secundario dependiente de la superficie del fondo, con lo que la caja embona dentro de la tapa superior redonda creando un vacío interno; resortes elastoméricos termoplásticos primero y segundo colocados uno sobre el otro ocupando el vacío interno con lo que durante un ciclo total de carrera los resortes termoplásticos primero y segundo quedan sujetos a doblado y flexionado; y medios para intertrabar moviblemente la tapa redonda superior y la caja con lo que cuando los resortes elastoméricos termoplásticos son precargados, movimiento substancial de la tapa superior con respecto a la caja puede ocurrir con sólo cambio pequeño de las fuerzas resistivas.The present invention relates to a side bearing unit for use with a rail car, said side bearing unit comprising; a generally round top cap, a top surface with a flat central portion, and an angular side portion tapered with respect to said central flat portion, a side wall integrally formed depending downward, a bottom surface with a centrally located dependent secondary solid stop and integrally formed and a primary stop surface adjacent to said side wall; a box including, a base portion prepared to engage the rail car, an integrally formed side wall extending upward with a primary stop portion to cooperate with the primary stop surface adjacent to the side wall, a solid stop centrally located secondary, integrally formed that extends upwards to cooperate with the secondary stop dependent on the bottom surface, whereby the box fits into the round top cover creating an internal vacuum; first and second thermoplastic elastomeric springs placed one on top of the other occupying the internal vacuum so that during a full stroke cycle the first and second thermoplastic springs are subjected to bending and flexing; and means for movably interlocking the upper round lid and case whereby when the thermoplastic elastomeric springs are preloaded, substantial movement of the upper lid relative to the case can occur with only a small change in resistive forces.
