CLUTCH FOR INSTALLING THE WHEEL PAIR WITH THE POSSIBILITY OF CHANGING THE TRACK WHEEL AND THE WHEELS PAIR WITH THE POSSIBILITY OF CHANGING THE TRACK Russian patent published in 2022 - IPC B61F7/00 B60B35/00 

FIELD: railway transport.

SUBSTANCE: inventions group relates to the field of railway transport, in particular to axle couplings for installing wheels, as well as to wheel sets with variable gauge, containing such couplings. The outer circumference of the first end of the coupling contains a mounting base for the wheel. The outer circumference of the second end contains sections of the outer slot along the axis of the coupling. The inner circumference of the second end of the coupling contains the first section of non-self-locking threads. The wheel pair contains an axle, a pair of wheels and a pair of axle couplings. Coupling threads have opposite directions of rotation. The wheels are fixed on the mounting bases of the couplings. The axle is provided with two sections of second non-self-locking threads. Each axle thread forms a pair with the coupling threads. The wheels are mounted on axles through axle couplings.

EFFECT: invention simplifies the design of wheel sets with variable gauge.
