FIELD: transport.
SUBSTANCE: this brake shoe consists of hot-rolled L-like steel section with wearing part and foot for attachment to car decelerator brake beam with mounting bores. Wearing part contact surface is composed by friction elements of composite alloy and makes not over 80% of total area of contact surface. Friction elements are shaped to solids of revolution secured in wearing surface bores. Composite power allot based on iron includes nickel, copper, graphite, molybdenum disulfide. Besides, it contains aluminium oxide and barite concentrate.
EFFECT: lower labour input in production, higher reliability, lower costs, higher wear resistance.
