FIELD: railway transport.
SUBSTANCE: invention relates to design of running gear of traction vehicle. Proposed traction vehicle contains body or frame 1, two-axle frameless bogies 3 with wheelsets 5 and axle boxes 6. Body or frame are furnished with pivots 13 with crossmembers 15 installed for rotation relative to vertical axis, connected by axle-box links 7 or tie-rods with axle boxes, with hinge joints filled up with grease or liquid lubricant placed in spaces of pivots, crossmembers and tie-rods or rubber-metal (silent block) joints with provision of rotation around three axles of each hinge joint or one hinge joint of each tie-rod relative to three axles, and second one, relative to vertical and cross axles. According to other design version, crossmembers indicated above are provided with side brackets which, in their turn, are connected by ends with axle-box links or tie-rods with axle boxes.
EFFECT: simplified design of running gear at improved dynamic and operating properties, reduced overall dimensions of traction vehicle and its frame in height, reduced mass of running gear and its cost.
