LOCOMOTIVE BOGIE Russian patent published in 2001 - IPC

FIELD: railway transport. SUBSTANCE: proposed bogie has frame resting on axle boxes of wheelsets through resilient members of first stage of spring suspension, resilient members of second stage of spring suspension, traction electric motors, side bearers, king pin and frame upper member. The latter has brackets located on its transverse central axis and coupled through two inclined radius rods with bogie frame. Frame upper member rests on resilient members of second stage of spring suspension installed with inclination in cross plane with tops towards longitudinal axis of bogie. Frame upper member is connected with cantilevers of traction motors by double-joint radius rods and is connected with locomotive frame by ring bolts-hooks. Invention improved operating characteristics of locomotive, reduces longitudinal dimensions of bogie at preservation of horizontal position of body at side elastic displacements under action of centrifugal forces, prevents spontaneous demounting and provides lifting of bogie together with locomotive in emergency. EFFECT: improved suspension of traction motor reducing action onto and bogie frame. 3 dwg
