A drawbar hitch vehicle with stabilization of a controlled undercarriage comprises a frame, a bogie truck connected thereto with at least one driven axle and a device for controlling rotation of the undercarriage including a folded pin in the form of two interconnected parts. The upper part of pin is connected to the frame, the lower part is made in the form of a lever pivotally mounted on the undercarriage and connected with its steered axle. To ensure greater safety of operation of articulated trucks it is equipped with a stabilizing mechanism, which comprises four stabilizing elements mounted coaxially on the upper portion of pin with possibility of rotation about its axis and interacting between each other by screw surfaces with an elevation angle that is greater than the friction angle. The upper stabilizing element is rigidly connected to the frame, the lower stabilizing element is mounted on the undercarriage, two intermediate stabilizing elements are rigidly interconnected. The upper part of the pin is connected to the frame with possibility of axial movement. |
