TROLLEY WITH MECHANISM OF WHEELSET RADIAL INSTALLATION Russian patent published in 2009 - IPC B61F5/38 

FIELD: machine building.

SUBSTANCE: trolley comprises two wheelsets and frame that includes cranked sides (2). Upper cranks (3) of sides rest with their ends via axlebox suspensions (4) on axlebox units (5) of wheelsets, and their lower cranks (6) are fixed by crossbars (7) into rectangular four-link chain of frame. Every side of four-link chain is hingedly connected by means of brackets, horizontal axes of shock absorbers of rubber and metal type, to pair of side levers (10), which are connected by their other ends hingedly via shock absorbers to brackets of axlebox units. Both pairs of levers are located in plane of frame four-link chain and together form mechanism for radial installation of wheelsets, in which levers are inclined to the side in the opposite manner and end with lugs (17), openings of which are perpendicular to each other. Brackets are made in the form of horizontal axlebox jaws (19) and vertical jaws (22) of lower cranks. Vertical (11) and horizontal axes of shock absorbers pressed into lugs are arranged with wedge journals fixed in wedge cuts of jaws by means of fastening elements, and are elastically aligned relative to ends of every lug by pair of block shock-absorbing orifices.

EFFECT: provides reliability and smoothness of trolley travel in curved sections of route.
