Abstract

PROCESSO DE DETERMINAÇÃO DE UMA GRANDEZA CARACTERÍSTICA REPRESENTATIVA DAS CONDIÇÕES DE ADERÊNCIA DE UMA RODA DE UM VEÍCULO EM RODAGEM SOBRE UM SOLO DADO. Processo de determinação de uma grandeza característica representativa das condições de aderência de uma roda de um veículo em rodagem sobre um solo dado, que compreende as etapas seguintes: impor às duas rodas de um mesmo eixo do dito veículo uma variação simultânea de ângulo de direção dada, a variação de ângulo de direção sendo de amplitude idêntica para as duas rodas mas de sentidos opostos; e medir a dita grandeza característica para uma pelo menos das duas rodas.
