Abstract

The vehicle transmission has a special clutch (3) behind a freewheel unit (5) to engage an air compressor (4) when retardation is required. The freewheel unit separates the engine from the drive and allows the engine to run with idling speed. The freewheel unit and clutch are in line coaxial to the main transmission shaft. A low friction thrust bearing (2) engages the air compressor clutch. A thrust lever driven by a linear motor (1) drives the clutch action. The linear motor is electrically controlled. The compressed air can be supplied continuously or in bursts. ADVANTAGE - Simple energy reclamation system, assists braking action. Saves fuel or limits performance.

Description

Die Erfindung betrifft eine Energierückgewinnungseinrichtung für Kraftfahrzeuge verschiedenster Art, die bei einem Verzö­ gerungsvorgang oder bei Bergabfahrten ihre kinetische Energie über die Reibungsbremsen und den Antriebsmotor in nicht mehr nutzbare Wärme umsetzen.The invention relates to an energy recovery device for motor vehicles of all kinds, which with a delay or kinetic energy when driving downhill about the friction brakes and the drive motor in no more Implement usable heat.

In dem vorgesehenen Verfahren wird dem ausrollenden bzw. schiebenden Fahrzeug bei vollständiger Gasrücknahme oder bei Abbremsung ein Luftverdichter über entsprechende Steuerungs- und Übertragungsorgane automatisch zugeschaltet, während der Antriebsmotor durch beispielsweise einen Freilauf von der Drehbewegung der Antriebswelle abgetrennt bleibt.In the proposed procedure, the rolling out or pushing vehicle with full gas withdrawal or at Braking an air compressor via appropriate control and transmission organs automatically switched on during the Drive motor by, for example, a freewheel from the Rotational movement of the drive shaft remains separated.

Als Übertragungsorgan zwischen Antriebswelle und Luftverdich­ ter kommt im einfachsten Falle eine Reibungskupplung zur An­ wendung, deren Primärteil zusammen mit der Gelenkwelle ro­ tiert und deren Sekundärteil mit dem Luftverdichter antriebs­ mäßig verbunden ist. Die Schließkraft für die Kupplung geht von einem Linearmotor aus und wird durch ein Axiallager auf die Kupplung übertragen.As a transmission element between the drive shaft and air compression In the simplest case, a friction clutch is used application, the primary part together with the drive shaft ro animals and their secondary part with the air compressor drive is moderately connected. The closing force for the clutch goes from a linear motor and is supported by an axial bearing transfer the clutch.

Der durch den Einsatz des Freilaufs ausbleibende Motorbrems­ effekt wird durch den Bremseffekt der bei der Pumparbeit des Luftverdichters entsteht, ersetzt.The lack of engine braking due to the use of the freewheel effect is due to the braking effect of the pumping work of the Air compressor is created, replaced.

Die gewonnene Druckluft wird zur Speicherung einem Behälter­ system zugeführt, wobei die Festlegung des idealen Speicher­ drucks der späteren Praxis vorbehalten bleibt.The compressed air obtained is used to store a container system fed, defining the ideal memory reserved for later practice.

Bei Einleitung der Arbeitsphase gelangt die gespeicherte Druckluft entweder kontinuierlich oder in Chargen zur Mitver­ wendung in den Antriebsmotor oder in einen angegliederten Zu­ satzmotor, um sich kraftstoffsparend oder leistungserhöhend auszuwirken. When the work phase is initiated, the saved one arrives Compressed air either continuously or in batches for application in the drive motor or in an attached Zu set engine to save fuel or increase performance impact.  

Stand der TechnikState of the art

Bekannt ist, daß bei elektrischen Schienenfahrzeugen Energie bei Bremsvorgängen zurückgewonnen wird.It is known that energy in electric rail vehicles is recovered during braking.

Bekannt sind auch hydrostatische Energiespeicherungsverfahren die bei Stadtbussen Verwendung finden und eine wirtschaftlich positive Bilanz aufweisen.Hydrostatic energy storage methods are also known which are used on city buses and are economical have a positive balance.

Auch Versuche, die beim Bremsen gewonnene Energie in einem Schwungrad zu speichern, sind bekannt.Also attempts to combine the energy gained when braking Storing the flywheel are known.

Andererseits sind Patentschriften über Fahrräder bekannt, bei denen der Bremsvorgang durch Komprimieren von Luft wirksam wird.On the other hand, patents on bicycles are known at which the braking process is effective by compressing air becomes.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, die kinetische Energie von Kraftfahrzeugen bei einem Verzögerungsvorgang so umzuwandeln und zu speichern, daß man sie während der Ar­ beitsphase nutzbringend einsetzen kann.The invention has for its object the kinetic Energy from motor vehicles during a deceleration process convert and save that you can use them during the ar can benefit from the work phase.

Lösungsolution

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die durch das schiebende Fahrzeug erzeugte Drehkraft in der An­ triebswelle durch entsprechende Übertragungs- und Steuerungs­ organe zum Antrieb eines Luftverdichters verwendet wird, wo­ bei die Ingangsetzung des Luftverdichters bei vollständiger Rücknahme des Gaspedals oder bei Betätigung des Bremspedals eingeleitet wird, während der Antriebsmotor abgetrennt bleibt, daß die erzeugte Druckluft gespeichert und später für den Antrieb des Fahrzeugs mitverwendet wird. The object is achieved in that the torque generated by the pushing vehicle in the An drive shaft through appropriate transmission and control organs used to drive an air compressor where when starting the air compressor at full Take back the accelerator pedal or when the brake pedal is pressed is initiated while the drive motor is disconnected remains that the generated compressed air is stored and later for the drive of the vehicle is also used.  

Weitere AusgestaltungFurther configuration

Die vorgesehene Energierückgewinnungseinrichtung soll vor allem der Energieverschwendung bei unwirtschaftlicher Fahr­ weise entgegenwirken. Dem Verfahren liegt daher die Absicht zugrunde, kinetische Energie von relativ schnell fahrenden Fahrzeugen beim Verzögern in eine gut verwertbare andere Energieform zu bringen. Die vielseitig einsetzbare Druckluft bietet sich hierzu als Energieträger in besonderer Weise an.The envisaged energy recovery device is intended to especially the waste of energy when driving uneconomically counteract wisely. The procedure is therefore the intention underlying kinetic energy from relatively fast moving Vehicles when decelerating into a usable other Bring energy form. The versatile compressed air offers itself as an energy source in a special way.

Der größte Nutzen ist bei Fahrzeugen, die überwiegend in Stadtgebieten verkehren, wegen der Häufigkeit der Abbremsun­ gen, zu erwarten. In den energieintensiven Beschleunigungs­ phasen wird dann die vorher gewonnene Druckluft unterstützend eingesetzt. Wie bei den an anderer Stelle erwähnten ähnlichen Verfahren, ist auch hier eine Kraftstoffersparnis von 20-30% zu erwarten und damit verbunden die Leistung eines Beitrags zur Umweltverbesserung.The greatest benefit is in vehicles that are predominantly in Urban areas operate because of the frequency of braking expected. In the energy-intensive acceleration The compressed air previously obtained is then used as a support used. As with the similar ones mentioned elsewhere Process, here too is a fuel saving of 20-30% to be expected and the performance of a contribution for environmental improvement.
