FIELD: transportation.SUBSTANCE: invention relates to railway transport, particularly, to high-speed freight cars bogies. High-speed freight cars bogie includes two mounted wheels with possibility of wheels independent rotation, braking system and two rigidly connected side frames. Side frames rigid connection is made by horizontal frame. Brake system is made in form of acting on wheel rims side surfaces and partially on their rolling surfaces clamping brake with two pairs of brake pads horizontal holders. Holders ends are supported on horizontal frame with possibility of mutual displacement along bogie and connected with possibility of holders with brake pads arranged in vertical plane oppositely directed transverse displacement. Bell cranks long arms are articulated with car braking system tie rod, and short arms are articulated with holders. On horizontal frame there are means of wobble oscillations suppressing devices. Bell crank axis is fixed in horizontal frame one of transverse beams middle part.EFFECT: enabling reducing vibrations of bogie.1 cl, 8 dwg |
