FIELD: railway transport.
SUBSTANCE: invention relates to design of car running gear. Proposed vehicle has frame 1, three-axle frameless bogies with wheelsets 4 and axle boxes. Frame is provided with pivots 10 arranged between middle and rear wheelsets of each bogie with crossmembers 12 mounted for rotation relative to vertical axis and connected by axle box links 6 or tie-rods with axle boxes of said wheelsets. Axle boxes of front and middle wheelsets are interconnected. Hinge joints are used being filled with grease or liquid lubricant in spaces of pivots, cross members and tie-rods or use is made of rubber-metal joints (silent blocks). According to other design version, crossmembers stated above are provided with side cantilevers which are, in their turn, hinge connected by ends with axle boxes.
EFFECT: simplified design of running gear, improved dynamic and service properties, reduced weight of running gear, wear of tires and flanges.
