FIELD: railway transport.
SUBSTANCE: invention relates to two-axle three-member bogies of freight cars. Proposed bogie contains overspring beam 1 with bogie center plate and two side bearers 8 pressed to thrust plates 10 of body side supports 11 by flexible members 4, springs of spring suspension through which overspring beam rests on side frames. Part of springs of springs of spring suspension is coupled with overspring beam through wedges 18 and wheelsets with axle box units. Flexible members are fitted in cavities 3 of overspring beam provided with holes 6 in lower sheet. Wedges coupling part of springs of spring suspension with overspring beam are made of antifriction material and are provided with cover plates made of friction material secured on their vertical walls and thrusting against friction plates of side frames.
EFFECT: provision of proportionally of bogie turning resistance moment to load of car, increased side stability of car body, efficiency of damping of spring suspension and service life of wedge friction mechanism.
