Abstract

"EMPARELHAMENTO DE FRICçãO". Um emparelhamento de fricção para um dispositivo de sincronização em mecanismos de mudança de velocidade de rodas dentadas emprega um corpo de fricção em forma de cone, que é constituído de um material ferroso, sendo que esse material ferroso na forma de acordo com a invenção apresenta uma dureza de 180 a 350 HV."Friction Pairing". A friction pairing for a timing gear synchronization device employs a cone-shaped friction body which is made of a ferrous material, which ferrous material in the shape according to the invention has a hardness from 180 to 350 HV.
