TWO-AXLE TROLLEY FOR HIGH-SPEED FREIGHT CAR Russian patent published in 2022 - IPC B61F3/08 B61H1/00 

FIELD: railway transport.

SUBSTANCE: invention relates to the field of railway transport, in particular to two-axle bogies of high-speed freight cars. The bogie contains two longitudinal frames, two transverse beams, a bolster. Axlebox units provide elastic interaction between axles of wheelsets and side frames. One transverse beam is rigidly connected to each longitudinal frame. The transverse beams are interconnected by rubber-metal or ball joints. The hinges are located on opposite sides of the longitudinal axis of the bogie. Brake linkage provides double-sided pressing of the pads on the wheel. The transmission contains two internal and two external triangels. The inner triangles are interconnected in the middle part by one puff of vertical levers. The end triangles are interconnected in the middle part by another tightening of the vertical levers. Puffs of vertical levers are oriented along the longitudinal axis of the bogie. The transverse beams are located between the inner triangles and are located between the bolster and the puffs of the vertical levers of the triangles.

EFFECT: increased stability in the movement of a two-axle bogie.
