Abstract
A semi-mounted plough has a rear chassis, the plough trailing behind a plough-towing tractor in a laterally pivotable or steerable manner by a vertically oriented joint. In order to compensate lateral pulling for the tractor, which is generated by the traction force of the plough about the vertical axis of the tractor, an energy accumulator is arranged, which generates a torque counteracting the lateral pulling.
Claims12
A semi-mounted plough, comprising:
- a plough frame of the semi-mounted plough;
- at least one of a right and left-turning plough body, of the semi-mounted plough, attached to the plough frame;
- a supporting chassis, of the semi-mounted plough, for supporting at least a portion of a weight of the plough on a ground;
- a towing hitch, of semi-mounted plough, for coupling the plough to a pulling device of a tractor;
- a drawbar, of the semi-mounted plough, that connects the plough frame with the towing hitch in at least one of a laterally steerable and pivotable manner by at least one vertical articulation axis;
- a first point of articulation, of the semi-mounted plough, which is arranged fixedly to the towing hitch and spaced apart from the at least one vertical articulation axis;
- a second point of articulation, of the semi-mounted plough, which is arranged fixedly to at least one of the drawbar and the plough frame;
- and
- an energy accumulator, of the semi-mounted plough, which is attached between the first and second points of articulation, such that at least one of a compressive force and a spring force of the energy accumulator produces a torque about the at least one vertical articulation axis, with the at least one of the compressive force and the spring force counteracting a lateral pulling for the tractor.
