Abstract

Un boggie de vagón ferroviario tiene una traviesa oscilante que tiene la forma de una viga hueca que tiene una porción central profunda y extremos poco profundos. La traviesa tiene una brida superior, una brida inferior y refuerzos interiores y exteriores que se extienden entre, que intersectan y se fusionan con las bridas superior e inferior. Un hueco de la placa central se ubica en la parte media de la brida superior, y se definen pasajes de la varilla del freno transversalmente a través de la traviesa. En algunas modalidades, los rebordes transversales corren debajo del hueco de la placa central. Los rebordes pueden ser curvos. Los rebordes pueden estar en alineamiento con las aberturas de la varilla. del freno en los diversos refuerzos. Pueden existir rebordes ascendentes que corren transversales a través de la brida inferior. Esos rebordes inferiores pueden terminar en alineamiento ascendente con las aberturas de la varilla del freno. Alternativamente, la porción inferior de la traviesa puede moldearse con un grosor mayor, hasta el fondo de las aberturas de la varilla del freno. En otras modalidades, la traviesa puede tener revestimientos o tubos de abertura de la varilla. del freno parcial o totalmente tubulares que se extienden a través de la traviesa por debajo de la placa central.
