Abstract

"DISPOSITIVO PARA DETERMINAR POSIçãO ANGULAR ABSOLUTA DE ELEMENTO GIRATóRIO, MANCAL E SISTEMA DE DIREçãO PARA VEìCULO A MOTOR". A invenção se refere a um dispositivo para determinar a posição angular absoluta de um elemento giratório com relação a uma estrutura fixa, compreendendo um codificador (1) provido com uma trilha (1a) multipolar principal e uma assim chamada trilha (1b) multipolar de "pip de giro', a trilha de pip de giro compreendendo M singularidades (1b1), meio (7) de medir a posição angular do elemento giratório com uma incerteza angular <30><sym>, na qual as M singularidades (1b1) representam individualmente uma posição angular absoluta do elemento giratório e são distribuídas na trilha (1b) de pip de giro com uma diferença angular entre cada uma delas que é maior do que 2<30><sym>. A invenção também se refere a um sistema de direção para um veículo a motor bem como um mancal compreendendo um tal dispositivo.
