LOCOMOTIVE TRACTION DRIVE EXPANSION CLUTCH Russian patent published in 2011 - IPC B61C9/40 B61C9/44 F16D3/60 

FIELD: transport.

SUBSTANCE: proposed expansion clutch comprises intermediate frame with central bore, two brackets with eye rings and con rods. Said con rods are directed along circumference in one direction and coupled by elastic universal joints with intermediate frame by their one ends and, by opposite ends, with hollow shaft pins arranged irregularly along the circumference. Note also that extreme joints of any three universal elastic adjacent joints are mounted asymmetrically relative to midplane that passes through central joint axle. Intermediate frame and hollow shaft hinged centers are located on different circumferences that have diameters maximum midplane constraints. Said frame is coupled with wheel pair ledges located along con rod axis via flat elastic elements made from highly elastic material.

EFFECT: higher reliability and longer life.
