Definitions
- the invention relates to an air compressor drive according to the generic term of claim 1.
- the invention has for its object to beat the gear noise by tooth flank to avoid in all operating states.
- Newer alternators have a multi-function regulator which regulates the characteristic the alternator affects.
- the control of the multifunction controller takes over the existing engine control unit.
- the alternator can be used when necessary Torque absorption can be prevented with a consumer.
- Another advantageous embodiment is characterized by the features of the claim 3 out.
- the consumer to which the alternator is connected is initially the electrical system itself, which consists of lighting, battery etc.
- the battery When the battery is charged you can use excessive voltage can be fed into the vehicle electrical system, insofar as it is in the vehicle electrical system allow integrated consumers.
- the energy supplied by the alternator is used and not lost senselessly.
- the alternator can also be connected to a resistor if that Electrical system not at all, or is not sufficiently receptive.
- the alternator Due to the current absorbed by the resistor, it is in all operating states the internal combustion engine possible that the alternator has a predetermined torque picks up, which keeps the tooth flanks on the pinion of the air compressor shaft in Stay in contact with the tooth flanks of the driving gear. This permanent Contact avoids tooth flank chatter and the resulting gear noise.
- Figure 1 shows the drive of an air compressor shaft 1 by means of a pinion 2 and one Gear 3.
- Gear 3 is an idler gear for driving a camshaft 4.
- the idler gear is driven by a crankshaft gear 5.
- Other Auxiliary units of the internal combustion engine such as e.g. Fan, cooling water pump, Power steering pump etc. is carried out via a belt drive, starting from a pulley 6.
- the air compressor shaft 1 is connected to a pulley 6 to drive additional ancillaries that reduce torque. Thereby to ensure that a torque is always present on the pinion 2, which the Raised tooth flanks prevented.
- FIG. 2 shows a circuit to implement the general inventive idea, which is always sufficient on the pulley 7 of the alternator 8 To generate torque in order to beat the tooth flank explained in FIG. 1 to avoid.
- the torque on the pulley 7 is required if other ancillaries switched on in the belt drive just no torque lose weight.
- the alternator 8 has an integrated multifunction controller, not shown here, which determines the control characteristic of the alternator.
- the alternator 8 supplies of the electrical system 10, which is shown here as the resulting resistance.
- Alternator 8 torque is adjustable in all operating states can the transmission noise of the air compressor described above reliably be avoided.
- a particular advantage of the invention is that apart from the resistor 14 and the switch 15 no additional components are required are.
- the alternator can be operated using the integrated multifunction controller so regulate that the pulley 7 continuously the desired at the moment Torque.

- Fig. 2
- einen Antrieb einer Lichtmaschine und eine Schaltung, um die Lichtmaschine mit definiertem Drehmoment zu belasten
Claims (4)
- Luftpresserantrieb, bei dem ein Ritzel auf der Kurbelwelle eines Luftpressers von einem Zahnrad mittels der Kurbelwelle einer Brennkraftmaschine angetrieben wird und von der Kurbelwelle des Luftpressers wiederum weitere Nebenaggregate wie z.B. Lenkhilfpumpe, Kühlwasserpumpe, Lichtmaschine etc. über einen Riementrieb antreibbar sind, dadurch gekennzeichnet, daß das Drehmoment der Lichtmaschine (8) im Zusammenwirken mit einem Verbraucher durch ein Motorsteuergerät (13) und einen Multifunktionsregler derart geregelt wird, daß bei nicht vorhandener, oder zu geringer Drehmomentaufnahme der restlichen Nebenantriebe an der Riemenscheibe (7) der Lichtmaschine (8) stets ein vorgegebenes Drehmoment verbleibt.
- Luftpresserantrieb nach Anspruch 1, dadurch gekennzeichnet, daß die Steuerung ein in die Lichtmaschine (8) integrierter Multifunktionsregler ist und dieser seine Befehle von einem Motorsteuergerät (13) erhält.
- Luftpresserantrieb nach Anspruch 1, dadurch gekennzeichnet, daß der Verbraucher das Bordnetz selbst ist und daß das Bordnetz zeitweise mit Überspannung in einem zulässigen Rahmen gespeist wird.
- Luftpresserantrieb nach Anspruch 1, dadurch gekennzeichnet, daß der Verbraucher aus dem Bordnetz und/oder einem Widerstand (15) gebildet wird.
