TRACTION MOTOR SUSPENSION ASSEMBLY Russian patent published in 2015 - IPC B61C9/50 

FIELD: transport.

SUBSTANCE: traction motor suspension assembly mounted axle bearing assemblies (1) and link (2) with kits ends coupled with motor housing and bogie frame by spherical and cylindrical silent blocks (3) and (4). Spherical silent block is fitted on axle (5) for axial displacement. Spacing between said block and said axle is filled with grease (10) with ferromagnetic nanoparticles while block bore houses permanent magnets (11). Top silent block tuber bush makes at least 2/3 of spacing on centres over suspension pivots.

EFFECT: higher reliability owing to ruled out seizure, friction factor variation and rubber bush stiffness changing.
