A self-propelled road roller with drawbar hauler includes a basic unit and working rolls. To enhance technological functionality of the roller through increase of the range of rolls pressure on earth, in the basic unit a tow-drag device is installed, this is connected to the basic unit in such way that its Π-like bearing frame is hinged to the axle of one of the rolls. The bearing platform is hinged to the basic unit. On the bearing platform installed are additional rolls, supplementary baffle plate and under-roller bearing, and the additional rolls are fixed to a bearing support with fixation element. The supplementary threshold is telescopically installed in the body of the bearing platform and is connected to the rods of hydro-cylinders with hinges, and the bodies of the hydro-cylinders are hinged to the bearing platform. The under-roller bearing is hinged to the bearing platform and the rods of the hydro-cylinder of control of its inclination. On the axle of the hinge of connection of the bearing platform and the basic unit con-rods are installed. On the Π-like frame a pulling and retaining winch with hydro-drive is installed. |
