  • Weight shifting mechanism for a powered locomotive bogie
    Patent number: 10464578
    Abstract: A weight shifting mechanism for a bogie frame is provided. The weight shifting mechanism may include an axle support pivotally coupled to the idler axle, a pusher link pivotally coupled to the axle support and forming a first fulcrum with the bogie frame, a support member pivotally coupled to the pusher link and the axle support, and an actuator mounted on the support member and actuatably coupled to the axle support via a live lever and a connector link. The live lever may form a second fulcrum with the support member and may be pivotally coupled to the connector link. The connector link may be pivotally coupled to the axle support. The actuator may selectively pivot the live lever about the second fulcrum to pivot the axle support about the idler axle and move the bogie frame relative to the idler axle.
