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) as quais são distribuídas angularmente de modo que o sinal (C) de pip de giro é arranjado de modo a, em combinação com os sinais A e B, definir seq³ências binárias as quais representam individualmente uma posição angular absoluta do codificador (1). A invenção também se refere a um sistema de direção para um veículo a motor e um mancal compreendendo um tal dispositivo.
