    摘要: A device for setting the length of a top rink (7) of an attaching device of a tractor (1) has a piston/cylinder unit (14) for length setting purposes. The piston/cylinder (14) has a displacement sensor (20) which records the respective actual length setting of the top link (7). The displacement sensor (20) generates an actual proportional length signal. A lift position sensor (13) is provided which generates an electric signal representing the respective actual lift position of the lower steering arms (4). A nominal length setting of the top link (7), which refers to the respective actual lift position, can be stored in a storage unit (33). When a new actual lift position is reached during the automatic mode of operation, it is possible to generate an electric control signal which corresponds to the nominal length setting of the top link (7). The signal is transmitted to the comparator of a control unit (34). The comparator compares the control signal with the actual length signal. The control unit controls the piston/cylinder (14) as a function of the deviation of the signals from one another, towards a nominal length setting. In this way it is possible, automatically, to achieve optimum kinematics for an implement attached to a tractor, without any outside interference.

    摘要: A device for measuring torque and the direction of rotation in a drive assembly, has a torsion element (9) which can be torque-loaded and rotatingly driven for the purpose of transmitting torque around an axis of rotation (8). A first transmitter element (16) attached in a rotationally fast way to the torsion element (9). The first transmitter element (16) is moved on a first rotational circle. A second transmitter element (34) is positioned at a reference distance from the first transmitter element 16. The second transmitter element (34) is connected in a rotationally fast way to the torsion element (9) and is moved on a second rotational circle. A sensor unit 35 is fixed and arranged at a distance from the axis of rotation (8). The sensor unit (35) senses the passage of the transmitter elements 16, 34 or of a reference edge or a reference surface and generates a corresponding sequence of signals. The transmitter elements generate signals of different lengths and, within the relevant measuring range, signal intervals of different lengths between the signals. An evaluation unit (36) receives the signals. The evaluation unit (36) determines the torque applied and the direction of rotation from the distance in terms of time between the signals.
