Abstract

"CHAVETA DA SAPATA DO FREIO COM BATENTE INTEGRAL". A presente invenção refere-se a uma chaveta da sapata do freio para prender uma sapata do freio do vagão ferroviário em uma contra-sapata do freio que tem um batente que engata a contra-sapata do freio para limitar a inserção da chaveta para dentro do rasgo de chaveta da contra-sapata do freio. O batente fica localizado na chaveta, de modo que quando ele engata a contra-sapata do freio, o joelho da chaveta engatará a orelha da sapata do freio e a espiga da chaveta ficará espaçada da contra-sapata do freio. Isso posiciona corretamente a chaveta para retenção da sapata do freio enquanto deixando espaço entre a espiga e a contra-sapata do freio para permitir acesso com uma ferramenta de alavanca para remoção segura subseqüente da chaveta.
