ABSTRACT:
A load adjustment device is provided having a throttle valve which determines the output of an internal combustion engine and is connected, fixed for rotation, to a throttle-valve shaft (32) which is mounted in a throttle-valve-shaft housing (30). The shaft has an acceleration-pedal side mechanical articulation side (33) and a setting-motor articulation side (34) with which there is associated a coupling element (45) for the mechanical uncoupling of the throttle-valve shaft from the setting motor within a defined angular region of the throttle valve; furthermore, a device is provided for reporting the instantaneous position of the coupling element to an electronic control device. In order, in the case of such a two-sided control of the throttle valve, to permit a structurally simple report of the position of the electric setting motor to the accelerator-pedal-side articulation side, the throttle-valve shaft is developed as a tube and the reporting device has a pass-through shaft (48) which passes through the throttle-valve shaft, a first transmission member (49) which is connected, fixed for rotation, with the pass-through shaft and the coupling element on the setting-motor articulation side and, on the accelerator-pedal-side articulation side, a second transfer member (50) which is connected, fixed for rotation, with the pass-through shaft and which cooperates with an actual-value detection device (18) associated with the control device.
