摘要： During monitoring of the driveline of an agricultural implement in respect of overloading and the degree of loading, from a first occurrence of slip, the slip revolutions occurring during a measuring cycle are added up. If the number of slip revolutions exceeds a permissible number of slip revolutions, a signal is generated indicating an overloading condition, a new measuring cycle beginning upon release of the signal to be able to take into account the effects resulting from a change in the behavior of the tractor driver, the nature of the signal being changed responsive to the speed differential between the input speed and output speed of a friction coupling permitting relative rotation. Furthermore, the condition of loading is indicated on the basis of the ratio of the actually measured number of slip revolutions to the number of maximum permissible slip revolutions so that the driver receives a warning prior to a blockage or case of overloading which may lead to overheating or destruction of the coupling serving to protect the implement.

摘要： A coupling device for a tractor has a frame (4) which is mounted on the rear underside (3) of the tractor (1). A drawbar (14), with a coupling member (15), is guided in the frame (4). The drawbar (14) is moved by a slide (18) and can be swung sideways about a vertical axis. Centering pieces (34) and stop blocks with centering faces (35) and stop faces (38) engage one another to laterally align and fix the drawbar (14). In a lower position the drawbar facilitates lateral swivelling movement about the connecting pin (22). In an upper towing position the drawbar (14) is laterally fixed by the centering pieces (34) and the stop blocks (38). This results in improved control of the coupling members associated with the to be towed implement through lateral alignment of the drawbar and its automatic transfer into its centered position.
摘要翻译：用于拖拉机的联接装置具有安装在拖拉机（1）的后下侧（3）上的框架（4）。具有联接构件（15）的拉杆（14）在框架（4）中被引导。牵引杆（14）通过滑块（18）移动，并且可以围绕垂直轴线横向摆动。定心片（34）和具有定心面（35）和止挡面（38）的止动块彼此接合，以横向对准和固定牵引杆（14）。在下部位置，牵引杆有助于围绕连接销（22）的横向旋转运动。在上牵引位置，牵引杆（14）由定心片（34）和止动块（38）横向固定。这导致通过牵引杆的横向对准及其自动转移到其中心位置来改进与被牵引工具相关联的联接构件的控制。
