FIELD: railway transport.
SUBSTANCE: invention relates to railway vehicles and design of frames of their bogies. Proposed frame of three-axle bogie has two longitudinal sidemembers 1, crossmembers 2, units of mounting of axle-box and central steps of spring suspension, units of mounting of vertical and horizontal vibration dampers, brackets to suspend brake equipment and brackets for mounting axle-box links. Longitudinal sidemembers are rigidly interconnected by crossmember arranged between axles of wheelsets equipped with device 4 for lubricating traction and brake force hinges transmission at level of wheelset axles or lower or higher to transmit said forces from bogie to frame or body of traction vehicle. Each longitudinal sidemember is provided with through vertical holes to pass axle-box brackets. According to other design version, longitudinal sidemembers are installed on said crossmember from top.
EFFECT: simplified design of frame, reduced overall dimension of frame in length, reduced metal usage, improved adaptability to manufacture, maintenance and repair.
