LUBRICANT CONSTRUCTION FOR VARIABLE WHEELSET AND VARIABLE WHEELSET Russian patent published in 2021 - IPC B61F7/00 B61F17/30 

FIELD: wheelset lubricating.

SUBSTANCE: invention relates to a structure for lubricating a wheelset with a variable track gauge and a wheelset with a variable track gauge. The lubrication structure contains wheels (1), an axle (2) and sliding mechanisms. The wheels are slidingly located at both ends of the axle, the sliding mechanisms are respectively connected to the outer sides of the wheels and are located in the axle boxes at both ends of the axle, while the wheels are unlocked and locked by the sliding mechanisms. A sealing structure (6) is provided between the inner side of each wheel and the axle, while the first cavity (7) is formed between the inner side of the wheel, the axle and the sealing structure, the second cavity (8) is formed between the outer side of the wheel and the sliding mechanism, and the third cavity (9) is formed between the sliding mechanism and the axle box. The wheel is provided with first oil injection channels (10) leading to the connection between the wheel and the axle, and the axle box is provided with second oil injection channels (11) leading to the sliding mechanism.

EFFECT: increased lubrication of the friction surface, reduced wear on key wear parts and extended overall life of the variable track wheelset.
