Abstract
Description
Der Erfindungsgegenstand betrifft einen Fahrwerksantrieb für KFZ, vorzugsweise für einen kleinen Aktionsradius und Betriebseinsätze mit relativ häufig wechselnden Treib- und Bremsphasen, wie z. B. bei Bussen für den Stadtbetrieb, Post-Zustell- und Sammelfahrzeugen, Taxis etc.The subject matter of the invention relates to a chassis drive for cars, preferably for a small radius of action and operations with relatively often changing Driving and braking phases, such as B. on buses for city operations, post delivery and collection vehicles, Taxis etc.
Unter vorgenannten Einsatzfällen wird ein großer Teil der gesamten Antriebsenergie wieder als Bremsenergie vernichtet. Eine wesentliche Energieeinsparung wird bekannterweise erreicht, wenn die Bremsenergie gespeichert und wieder dem Fahrwerksantrieb zugeführt wird. Dieses Verfahren ist in letzten Jahren durch Forschungsinstitute und Industrie - wesentliche Anstrengungen sind auch durch BMfT-Mittel forciert worden - gründlich erforscht und entwickelt worden. So beträgt z. B. bei Stadtbussen die durch Bremsen wieder vernichtete Antriebsenergie bis zu 40%. Bei regenerativer Wiederverwendung dieser Bremsenergie können 10-30% der Treibstoffkosten eingespart werden.A large part of the above-mentioned applications of the total drive energy again as braking energy destroyed. A significant energy saving will be famously achieved when the braking energy is stored and fed back to the chassis drive becomes. This process has been completed in recent years Research institutes and industry - essential efforts are also promoted by BMfT funds been researched and developed thoroughly. So is z. B. on city buses by braking again destroyed drive energy up to 40%. At regenerative reuse of this braking energy can save 10-30% of fuel costs will.
Ein wesentliches Problem der regenerativen Bremsenergie- Wiederverwendung besteht nicht nur in verlustbehafteter Speicherung selbst, sondern auch in Transformation oder Übertragungsverlusten vom Fahrwerk zum Speicher und zurück. Meist wird bei den verschiedenen Forschungs- und Studienobjekten die als mechanische Energie anfallende Bremsenergie zur Übertragung und Speicherung in verschiedene andere Energieformen, wie z. B. hydr. Druckenergie, elektrische Energie oder wieder in kinetische Energie umgewandelt - und dies noch einmal zurück zum Zwecke des Antreibens. Abgesehen von den dafür erforderlichen konstruktiv aufwendigen Hilfseinrichtungen, leidet die Effektivität des Energietransportes bei solchen Transformationen stark.A major problem of regenerative braking energy Reuse is not just lossy Storage itself, but also in transformation or transmission losses from the chassis to Memory and back. Mostly with the different Research and study objects as mechanical Energy generated braking energy for transmission and Storage in various other forms of energy, such as B. hydr. Pressure energy, electrical energy or converted back into kinetic energy - and back again for the purpose of driving. Apart from the structurally complex required for this Aid facilities, effectiveness suffers of energy transport in such transformations strong.
Eine wesentliche Aufgabe vorliegender Erfindung besteht darin, den Energieverlust beim Energietransfer Fahrwerk-Speicher-Fahrwerk und den konstruktiven Aufwand möglichst klein zu halten.An essential object of the present invention is the loss of energy when transferring energy Chassis storage chassis and the design effort to keep it as small as possible.
Im Rahmen der Bemühungen nach verbesserten alternativen Antriebsformen steht auch das Bestreben nach abgas- und geräuschemissionsärmeren Konzeptionen im Vordergrund, dem besonders der Einsatz elektrischer Fahrzeugantriebe gerecht wird. Da der Einsatz solcher Antriebskonzeptionen wegen seines eingeschränkten Aktionsradius für den innerstädtischen Einsatz prädestiniert ist, erscheint es aus Effektivitätsgründen zwingend geboten, die Bremsenergierückgewinnung mit ihren eingangs angeführten Vorteilen in das Antriebskonzept mit einzubeziehen. Erfolgt die Bremsenergiespeicherung auf rein elektrischer Basis, d. h. mittels des eigentlichen Antriebssystems, wirken sich folgende bekannte nachteilige Effekte aus:As part of efforts to improve alternative Forms of drive are also the endeavors concepts with lower emissions and lower emissions Foreground, especially the use of electrical Vehicle drives. Because the use of such Drive concepts because of its limited Action radius predestined for inner-city use it appears for reasons of effectiveness imperative to use the braking energy recovery the advantages mentioned in the drive concept to include. The braking energy is stored on a purely electrical basis, d. H. by means of of the actual drive system, the following effects known adverse effects from:
Durch spontane Laststöße, wie sie im KFZ-Einsatz und ganz besonders bei Bremsenergie-Rückgewinnungseinrichtungen vorkommen,Through spontaneous load surges, such as those used in vehicles and especially in brake energy recovery systems occurrence,
-
- leidet und vermindert sich die Ladekapazität und
Lebensdauer der Batterien,
- Antriebsmaschine, Batterien sowie Stell- und Steuerorgane müssen auf die maximalen Spitzenleistungen ausgelegt werden, was einen großen Bauaufwand bedingt.- suffers and decreases the charging capacity and life of the batteries,
- Drive machine, batteries as well as actuators and control elements must be designed for the maximum peak performance, which requires a lot of construction.
Werden weitere, andere Energiespeichersysteme eingesetzt, bedarf es zusätzlichen Aufwandes an Übertragungselementen, Geräten, Energiespeichern usw., was besonders für kleinere Fahrzeugkonzeptionen eine ökonomisch nicht vertretbare Lösung darstellt.If other, other energy storage systems are used, additional transmission elements are required, Devices, energy storage, etc., something special an economical one for smaller vehicle designs represents unacceptable solution.
Aufgabe vorliegender Erfindung ist die Schaffung einer Elektromotor-KFZ-Antriebskonzeption mit Bremsenergie- Rückgewinnung bei geringem Bauaufwand.The object of the present invention is to create a Electric motor vehicle drive concept with braking energy Recovery with little construction effort.
Die Lösung besteht in den in den Ansprüchen und Beschreibungen angeführten Merkmalen.The solution is in the claims and descriptions mentioned features.

-
- sind keine wesentlichen zusätzlichen Aggregate
zur Energiespeicherung und Transformation erforderlich;
- der Speicher, d. h. die entsprechende Ausbildung des obligaten Antriebsmotors erfordert einen verhältnismäßig geringen Mehraufwand;
- elegante, einfache und vor allem effektive Energietransformation zwischen Fahrwerk und Speicher mittels stufenlosem Getriebe;
- stufenloses Getriebe stellt wegen seines hyperbolischen M t -n-Wandlungscharakters ein ideales Anpassungsglied für den KFZ-Antrieb dar;
- die elektrischen Einrichtungen werden von Spitzenbelastungen verschont, sowohl Anfahr- und insbesondere Brems-Belastungen können weitgehend durch kinetische Energie abgedeckt und die elektrischen Einrichtungen schwacher ausgelegt werden;
- durch die Bremsenergie-Rückgewinnung kann generell die Batterie kleiner ausgelegt, oder der Aktionsradius des Fahrzeuges vergrößert werden.- no significant additional aggregates for energy storage and transformation are required;
- The memory, ie the corresponding training of the mandatory drive motor requires a relatively small additional effort;
- Elegant, simple and, above all, effective energy transformation between the chassis and the accumulator using a continuously variable transmission;
- Because of its hyperbolic M t - n conversion character, the continuously variable transmission is an ideal adapter for the motor vehicle drive;
- The electrical devices are spared peak loads, both start-up and especially braking loads can be largely covered by kinetic energy and the electrical devices can be designed weaker;
- Due to the braking energy recovery, the battery can generally be made smaller, or the vehicle's radius of action can be increased.
