ABSTRACT:
A load adjustment device has a throttle valve (9) which determines the output of an internal combustion engine and is connected, fixed for rotation, with a throttle-valve shaft (36) arranged in a throttle-valve housing. A control element cooperates with a driver 4 coupled to an accelerator pedal (1), and acts on the throttle-valve shaft (36). In addition to the one driver (45), two further drivers (49, 51) forming a free-travel hook (47) are provided, having at least two stops between which a driver (52) of the throttle-valve shaft (36) is adjustably received. By the use of the first driver (45) between the electric motor (14) and the throttle-valve shaft (36), the coupling provided on the driven shaft (39) of the electric motor (14) can be dispensed with in simple manner. By the advantageous development of the free-travel hook (47) in combination with the two drivers (49, 51) and the springs (46, 70), the throttle-valve shaft (36) is acted on by pressure from both sides so that, upon upward control and downward control, no sudden change in torque occurs upon the displacement of the throttle valve (9).
