Avaliação do Desempenho Tribológico e Térmico de Materiais de Atrito Durante o Processo de Frenagem

Abstract: RESUMONeste artigo, buscou-se verificar os parâmetros de operação de um sistema de freio a disco para motocicletas utilizando-se uma bancada de ensaios baseada no procedimento Krauss, descrita pela norma ABNT NBR 6143/1995 [1]. Optou-se por conduzir um Experimento Fatorial 2³, em que os três fatores de controle considerados (tipo de disco de freio, tipo de pastilha e o valor da pressão de acionamento da manete de freio) foram alterados deliberadamente em dois níveis cada. Buscou-se analisar as propriedades do… Show more

“…Pinto et al 29 conducted an experiment factorial 2 3 , in which the three control factors considered (brake disc, chip, and the brake lever on working pressure) have changed on two levels. Some authors [12][13][14][15]17 also evaluated brake mass loss concerning the brake service temperature, pressure, and vehicle speed; nevertheless, these three variables were not evaluated together to determine the worst response in dynamometer tests.…”

“…According to Machado Pinto et al [ 1 ], automobiles and transportation vehicles have undergone several changes and improvements over the years, aiming to provide more comfortable and safer locomotion. These technological advances experienced by the automotive sector have allowed vehicles to become increasingly faster and with higher load-carrying capacities, which has also led to the need for the design and manufacture of more efficient brakes.…”
