Ncreasing longevity drum brakes biaxial highway vehicles under operation

Abstract

n a typical case considered abrasive wear on brakes drum "duo-duplex" "duplex" and "simplex" during the operation of transport and technological machines. Obtained laws that take into account the rate of brake force distribution, design parameters coupled parts and wear rate for a given period of operation to determine the limit of wear-coupling drum pad that can serve as a criterion reliability prediction brakes mounted on the rear axle axle transport vehicles. To prolong the life of drum brakes in certain conditions axle transport vehicles should be increased: - ratio constant brake force distribution between the axles; - structural factors of the rear brakes; - friction surface width (width of pads); - durability of materials and drum pads. Determined pattern change wear drum brakes axle motor vehicles in operation depending on changes in the coefficient brake force distribution between the axles, their geometric parameters and rate of wear that can make recommendations on the introduction of a law brake force distribution between the axles transporter and terms replace worn parts drum brakes during operation. The aim is to increase durability drum brakes axle transport vehicles due to the choice of the coefficient brake force distribution between the axles, which would be in operation provide the lowest level of depreciation coupled parts.
