- Steuereinrichtung zum Steuern einer Leistung einer Antriebsmaschine, insbesondere einer Antriebsmaschine eines Fahrzeugs, mit einem die Leistung der Antriebsmaschine bestimmenden Stellelement (4, 4b, 4d), mit einem Stellantrieb (16) zum Verstellen des Stellelements (4, 4b, 4d) zwischen einer ersten Endstellung (21) und einer zweiten Endstellung (22), sowie mit einer bei Ausfall des Stellantriebs (16) das Stellelement (4, 4b, 4d) in eine Ruheposition (20) stellenden Federeinrichtung (8), wobei sich die Ruheposition (20) zwischen der ersten Endstellung (21) und der zweiten Endstellung (22) befindet, dadurch gekennzeichnet, daß ein mit dem Stellelement (4, 4b, 4d) wirkverbundenes Zwischenglied (10) vorgesehen ist, wobei die Federeinrichtung (8) über eine erste Federanlenkung (31) auf das Zwischenglied (10) in Richtung der ersten Endstellung (21) und über eine zweite Federanlenkung (32) in Richtung der zweiten Endstellung (22) bis zum Erreichen der Ruheposition (20) wirkt und zwischen der Federeinrichtung (8) und dem Zwischenglied (10) mindestens eine Übersetzung (6, 6a, 6b) vorgesehen ist, durch die eine erste Wirkung der Federeinrichtung (8) auf das Zwischenglied (10) zwischen der ersten Endstellung (21) und der Ruheposition (20) in Richtung der zweiten Endstellung (22) größer ist als eine zweite Wirkung der Federeinrichtung (8) in Richtung der ersten Endstellung (21).
- Steuereinrichtung nach Anspruch 1, dadurch gekennzeichnet, daß bei in der ersten Endstellung (21) stehendem Stellelement (4, 4b, 4d) die Antriebsmaschine mit minimaler Leistung und bei in der zweiten Endstellung (22) stehendem Stellelement (4, 4b, 4d) die Antriebsmaschine mit maximaler Leistung arbeitet.
- Steuereinrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß das Stellelement (4, 4b, 4d) und das Zwischenglied (10) drehbar gelagert sind und die erste Wirkung der Federeinrichtung (8) ein erstes Drehmoment, sowie die zweite Wirkung der Federeinrichtung (8) ein zweites Drehmoment sind.
- Steuereinrichtung nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, daß sich die Übersetzung (6, 6a, 6b) zusammensetzt aus einer ersten Getriebestufe (6a) zwischen der ersten Federanlenkung (31) und dem Zwischenglied (10), sowie einer zweiten Getriebestufe (6b) zwischen der zweiten Federanlenkung (32) und dem Zwischenglied (10).
- Steuereinrichtung nach Anspruch 3 und 4, dadurch gekennzeichnet, daß die erste Getriebestufe (6a) von der ersten Federanlenkung (31) auf das Zwischenglied (10) die Drehzahl um einen ersten Übersetzungsbetrag erhöht und die zweite Getriebestufe (6b) von der zweiten Federanlenkung (32) auf das Zwischenglied (10) die Drehzahl um einen zweiten Übersetzungsbetrag erhöht, wobei der erste Übersetzungsbetrag größer ist als der zweite Übersetzungsbetrag.
- Steuereinrichtung nach Anspruch 4 oder 5, dadurch gekennzeichnet, daß die erste Getriebestufe (6a) eine Zahnradübersetzung ist.
- Steuereinrichtung nach Anspruch 4, 5 oder 6, dadurch gekennzeichnet, daß die zweite Getriebestufe (6b) eine Hebelübersetzung ist.
- Steuereinrichtung nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß die zweite Federanlenkung (32) über ein Anschlagstück (12) auf das Zwischenglied (10) wirkt, bis das Anschlagstück (12) in der Ruheposition (20) an einem Ruheanschlag (20) zur Anlage kommt.
- Steuereinrichtung nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß die zweite Federanlenkung (32) auf das Zwischenglied (10) wirkt, bis die zweite Federanlenkung (32) in der Ruheposition (20) an einem Ruheanschlag (20) zur Anlage kommt.
- Steuereinrichtung nach einem der Ansprüche 8 oder 9, dadurch gekennzeichnet, daß der Ruheanschlag (20) einstellbar ist.
- Steuereinrichtung nach einem der Ansprüche 8 bis 10, dadurch gekennzeichnet, daß der Ruheanschlag (20) einen Notlaufpunkt der Antriebsmaschine bestimmt.
- Steuereinrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß der Stellantrieb (16) über das Zwischenglied (10) mit dem Stellelement (4, 4b, 4d) verbunden ist.
- Steuereinrichtung nach Anspruch 12, dadurch gekennzeichnet, daß zwischen dem Stellantrieb (16) und dem Zwischenglied (10) ein eine Drehzahl des Stellantriebs (16) herabsetzende Getriebeübersetzung (14) vorgesehen ist.
- Steuereinrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß das Stellelement (4, 4b, 4d) eine an einer Drosselklappenwelle (4w) befestigte und um eine Drehachse (4x) drehbar in einem Gehäuse (36) gelagerte Drosselklappe (4d) ist und die Federeinrichtung (8) zum axialen Spannen der Drosselklappenwelle (4w) gegen einen dem Gehäuse (36) zugeordneten Axialanschlag (34, 34a) dient.
- Steuereinrichtung nach Anspruch 14, dadurch gekennzeichnet, daß sich die Federeinrichtung (8) zum axialen Spannen der Drosselklappenwelle (4w) gegen den Axialanschlag (34, 34a) in Gegenrichtung am Gehäuse (36, 36d) abstützt (Fig. 7).
- Steuereinrichtung nach Anspruch 8 und 14, dadurch gekennzeichnet, daß sich die Federeinrichtung (8) über das Anschlagstück (12) am Gehäuse (36) abstützt (Fig. 4).
- Steuereinrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß die Federeinrichtung (8) ohne Unterbrechung auf das Stellelement (4) wirkt.
