摘 要：
The utility model relates to road
technology, in particular to the means of position control of the articulated frame of the motor grader during the operation of the latter. The technical result of the utility model is to reduce the complexity of preparatory operations in the mode of operation of a motor grader with a break in half frames. The device for turning the articulated frame of the motor grader (Fig. 3) contains the front 3 and rear 4 half-frames, connected by the pivot joint 5, as well as two identical hydraulic cylinders 1, 2 of the front half-frame 3 rotation relative to the rear 4 in the horizontal plane. Swing cylinders 1, 2 are made with two opposed piston groups, therefore, in the straight (without kink) position, the half

frames 3, 4, the cavities of the hydraulic cylinders 1, 2 are locked. In this case, the direct position of the half-frames is
provided by electro-hydraulic distributors and hydraulic locks, which ensures the possibility of reliable fixation of the half-frames 3, 4 in a straight (without bending) position. When the semi-frame 3 is turned, for example, to the right, the piston groups of hydraulic cylinders 1, 2 are triggered in such a way that the rod 6 is retracted and the rod 7 is pulled. position. Similarly, the half-frame 3 is rotated to the left. 3 ill. 主权项：
