LAYOUT SCHEME OF TRUCK CHASSIS Russian patent published in 2016 - IPC B62D7/02 

FIELD: machine building.

SUBSTANCE: invention relates to design of truck chassis, primarily of mine dump trucks. Layout scheme of truck chassis comprises frame on which are mounted drive axles with propulsors. To turn drive axles with propulsors are used hydraulic cylinders installed on frame. Each driving axle is equipped with rotary housing with an attached supporting and turning wheel, consisting of fixed and movable rings with running tracks, in contact with rolling bodies arranged there between. Movable or fixed ring of supporting and turning wheels are fixed on frame and corresponding to fixed or movable rings are fixed on rotary bodies, and hydraulic cylinders are connected with rotary bodies with possibility of providing their turning together with propellers relative to frame. Between Rotary bodies with supporting and turning wheels and drive axles are mounted suspension elements. Drive axles have levers, arms of which are connected with suspension, which are connected with rotary bodies with moving ring of supporting and turning wheel. At ends of frame there are paired limiters of rotation of rotary bodies with moving ring of supporting and turning wheel of drive axles. They are designed to limit rotation by means of stops of axles of vehicle by angles α and δ.

EFFECT: simplified design of said truck chassis layout scheme.
