ARTICULATED MACHINE CONTROL SYSTEM Russian patent published in 2019 - IPC B62D5/06 

FIELD: machine building.

SUBSTANCE: invention relates to transport machine building. Control system of articulated machine consists of power and process trolleys connected by coupling device with transverse rod and control elements connected with slide valves of corresponding hydraulic control valves. Hydraulic control valves are hydraulically connected with appropriate hydraulic cylinders of power and process trolleys, pressure line with pump and drain line of hydraulic tank. Housings of hydraulic control valves are made with possibility of displacement in longitudinal direction and are connected to rods of corresponding 1st and 2nd additional hydraulic cylinders, which are hydraulically connected with 3rd and 4th additional hydraulic cylinders. 3rd hydraulic cylinder is kinematically connected with power trolley and transverse rod. 4th hydraulic cylinder is kinematically connected with process trolley and transverse rod. Each section of pressure line two-section pump is hydraulically connected with appropriate hydraulic control valves. Cavities of additional hydraulic cylinders via check valves are hydraulically connected by make-up lines connected with hydraulic tank via drain line and throttle installed in it.

EFFECT: simplified design and higher accuracy of control.
