摘要
In a tractor driving gear with drive shaft (11) for implements (12) with overload protection by means of a coupling (3) whose maximum transmissible moment can be adjusted by the action of a control unit (16) on the pressure acting on the coupling (3), speed of revolution sensors (13, 14) are arranged on the driving and on the driven part of the coupling in order to increase accuracy and in order to achieve staggering of the slip moments virtually as under real conditions, control elements (21, 22) are provided for adjusting a first maximum moment and a second maximum moment lying above it, and a summing amplifier forms an input signal (44), dependent on the operating conditions, for a control member (17) which adjusts the pressure acting the coupling (3). The output signal of a slip monitor (33) acts on the summing amplifier. IMAGE
