Abstract
In an adjusting device for a throttle flap of an internal combustion engine driving a motor vehicle, wherein further influencing and correcting variables can be introduced via an electric servo-motor into the mechanical transmission device connecting the accelerator pedal and the throttle flap. For this purpose a planetary gear of a transmission device has a rotatable outer gear wheel connected to the accelerator pedal, a sun gear wheel connected to the servo-motor and the planet carrier connected to the throttle flap.
Claims20
Adjusting device for a throttle flap of an internal combustion engine of a motor vehicle, including:
- a mechanical transmission means between an actuating lever and the throttle flap for transmitting movement of the actuating lever to the throttle flap and a connecting means for introducing other influencing and correcting variables into the transmission means independently of the movement of the actuating lever;
- said connecting means including a servo-motor adjustable as a function of these influencing and correcting variables;
- said servo-motor moving a sun gear wheel of the transmission means;
- the transmission means including a planetary gear having three rotatable elements, namely an outer gear wheel, said sun gear wheel and planet carrier carrying planet gear wheels;
- and
- wherein the outer gear wheel, the sun gear wheel and the planet gear wheels are each connected only to one of the actuating lever, to the servo-motor and the throttle flap.
