ABSTRACT:
A load-shifting device has a control element (4a, 4b) which acts on a setting member (7,9) which determines the output of an internal combustion engine. The control element is adapted to be connected to an accelerator (1) and is controllable by an electric setting drive (10) which cooperates with an electronic controller (12). The load-shifting device provides that the setting member includes a main setting member (7) with which there is associated a first control-element part 4a which is coupled with the accelerator. The setting member further includes an auxiliary setting member (9) with which there is associated a second control-element part (4b). The setting path of the first control-element part is limited in idling direction by an idle stop (LL). The second control-element part can, upon application of the first control-eleemnt part against the idling stop, be moved within its idling control range relative to the first control-element part by the electric setting drive. The load-shifting device makes it possible, with simple structural development, to control the internal combustion engine over its entire load range and, in particular by the electric setting drive, over its idling range.
