Abstract

SE PRESENTA UN APARATO PARA FRENAR EL MOVIMIENTO VERTICAL RELATIVO ENTRE DOS MIEMBROS VERTICALES QUE INCLUYE UNA RAMPA MONTADA SOBRE UNO DE LOS MIEMBROS PARA OPONERSE A UNA CARA VERTICAL SOBRE EL OTRO. SI EL MIEMBRO DE RAMPA SE ACELERA HACIA ABAJO UN RODILLO DE CUÑA SE ACUÑA ENTRE LA RAMPA Y LA CARA VERTICAL. ESTE RODILLO ESTA SOBRE UNA VARILLA DE CORREDERA QUE NORMALMENTE COMPRENDE UN MUELLE SOPORTADO EN EL FONDO DE LA RAMPA, PERO LA ACELERACION HACIA ABAJO DE LA RAMPA DA COMO RESULTADO LA EXPANSION DEL MUELLE Y EL MOVIMIENTO DEL RODILLO DE CUÑA A LA POSICION DE ACUÑAMIENTO PARA DETENER LA ACELERACION.
