Abstract
Patente de Invenção: <B>"SISTEMA DE AMORTECIMENTO PARA VAGãO DE CARRO DE TRILHO<D>". Um sistema de amortecimento de vagão de carro de trilho inclui um cavalete com uma cavidade de cavalete tendo uma parede inclinada interior, uma armação lateral tendo uma superfície resistente ao desgaste da coluna que faceia a dita cavidade, e uma cunha de atrito posicionada dentro da cavidade. A cunha tem um corpo com uma área de contato faceando a parede inclinada da cavidade do cavalete, que é formada por um par de superfícies planares espaçadas geralmente paralelas com um recesso entre elas. A parede inclinada da cavidade do cavalete tem um extensão para fora alongada alinhada com o recesso da cunha e estendendo-se para ele, com a extensão funcionando para resistir ao movimento lateral da cunha dentro da cavidade do cavalete. O corpo da cunha tem uma área de contato que faceia a superfície resistente ao desgaste da coluna da armação lateral, que é formada por um par de superfícies espaçadas planares geralmente paralelas, com um recesso entre elas. A superfície resistente ao desgaste da coluna da armação lateral tem uma extensão vertical alinhada com o recesso da cunha e estendendo-se para ele, com a extensão limitando o movimento lateral relativo entre o cavalete e a armação lateral.
