FIELD: rail transport.
SUBSTANCE: this invention covers bushes for lever brake systems with low friction factor and lubrication-free. The bush is made of a composite material including fibrous filler, adhesive and bonding agent. Fiberglass and/or carbon fiber is used as fibrous filler; molybdenum disulfide is used as adhesive; and polyamide resin is used as bonding agent.
EFFECT: increase of bush service life due to qualitative and quantitative ratio of bush components.
