COMPARATIVO ENTRE BUCHAS DE BRONZE E BUCHAS DE POLIPROPILENO APLICADAS EM FEIXES DE MOLAS DE SUSPENSÃO INSTALADOS EM VEÍCULOS TIPO ÔNIBUS

Abstract

Spring bundle bushings are common parts, but require training and training of personnel for eventual replacement and preventive behavior. Exist Also, the cost of applying grease between the clamping pin and the bushing. Looking at this senary, the article presents a comparison between bushings made with bronze and bushings made of polypropylene, whose purpose will be the verification of the mechanical strength, durability and cost of spring-loaded one of bushings over the other. As a result, it is estimated that polypropylene bushings stronger than ordinary bronze bushings and do not generate noise or wear the pins that fix the chassis beams.
