ARRANGEMENT FOR INFLUENCING THE JOINT ANGLE BETWEEN SECTIONS OF AN ARTICULATED VEHICLE

摘要

The invention relates to the hinged coupling connecting the sections of an articulated motor vehicle, mainly of an articulated bus, for influencing the jack-knifing movement of said sections to prevent development of excessively high angular speeds of jack-knifing. On the vehicle, one or two hydraulic working cylinders are arranged, the piston rods of which are coupled to one section while the cylinders are connected to the other section, each working cylinder being linked up with a fluid-replenishing and equalizing reservoir, expediently, with a common pressurized hydropneumatic unit, with a check valve and a pressure limiting valve being arranged parallel with the check valve in each of said connecting lines, having further connecting lines (16a, 30a, 36a and 16b, 30b, 36b) coupled to the working chambers (10a and 10b) of the cylinders, said connecting lines being branched off a common line (18), in the connecting lines (36a, 36b) of each working cylinder (6a, 6b) a check valve (37a, 37b) closed toward said branched-off common line (18), is accommodated, in the lines (30a, 32a, 35a and 30b, 32b, 35b), between each of said check valves (37a, 37b) and working spaces (10a and 11a) of the working cylinders (6a and 6b) parallel chokes (31a, 33a, 34a and 31b, 33b, 34b) are connected into peripheral groove (27a and 27b) of a rotary valve (24) provided with control edges (29a and 29b) and always being in an angular position proportional to the momentary joint angle ( beta ) of the vehicle (1).
