BLOCKING MECHANISM FOR A VARIABLE GAUGE WHEELSET, VARIABLE GAUGE WHEELSET, AND VARIABLE GAUGE BOGIE Russian patent published in 2022 - IPC B61F7/00 

FIELD: railways.

SUBSTANCE: group of inventions relates to the field of railway transport, in particular, to blocking mechanisms for variable gauge wheelsets, to variable gauge wheelsets, and to bogies containing such wheelsets. The mechanism comprises a traction electric magnet and a blocking pin. The electric magnet comprises a solenoid and a mobile core. The end of the core is connected to a locking pin Blocking holes are located on the inner hub of the wheels at intervals in the axial direction. The core can insert and remove the pin from the holes. The blocking mechanism comprises two connected sleeves. The sleeves consist of an end cap and a cylinder. The cover of the first sleeve comprises a through axial hole and is tightly connected to the wheelset axle by means of the through axial hole. The cover of the second sleeve is attached to the cylinder of the first sleeve. The cylinder of the second sleeve extends towards the wheel in the direction along the circumference of the second end cover. The wheel hub is passed into the first cylinder and coupled with the first cylinder so as to be able to slide. A through hole is located on the inner wall of the first cylinder in the direction corresponding to the blocking hole.

EFFECT: time required to change the track gauge is reduced.
