in dem Projekt zero-emission 3 unit
Generation one geht es um den
Entwicklung der Demonstration und den
messtechnischen Nachweis eine
elektrischen Antriebseinheit die ohne
Emissionen ist und zwar adressieren wir
damit zwei Themen einmal die
Klimaerwärmung und zum anderen vor allem
auch das Thema Gesundheit bei der
Klimaerwärmung sind die Treibhausgase
wie CO2 bekannt die aus dem
Verbrennungsprozessen stammen bei der
Gesundheit sind es NOx und vor allem
auch Feinstaub und mikroplastik der
Feinstaub entsteht hauptsächlich
Immobilienbereich bei bremsabtrieben und
das mikroplastik bei iPhone ablegen
in diesem Fahrzeug ist eine
lamellenbremse direkt in den
Elektromotor integriert diese Bremse ist
komplett geschlossen und wird dann bei
Bedarf mit Öl entsprechend temperiert
bzw auf die abkleber dort ausgetragen so
dass wir hier keine Emissionen in die
Umgebung in die Umwelt am bremsabtrieben
haben
bei den abtrieben aus dem Reifen haben
wir eine ganze Reihe Topologie
alkoholdynamisch simuliert wir haben
hier eine dann gewählt die halt in der
Lage ist bis zu 50 km/h über
entsprechende an- und Absaugungen aber
auch die Strömungsführung komplett die
reifenabriebe abzusaugen und wir hoffen
dass in einem wlte pc-plus wird dann die
70 bis 90% Vermeidung der
reifenabriebemissionen erreichen werden
hier am Rollenprüfstand wird das
Fahrzeug erst einmal auf die Rolle
reingefahren und dann wird entsprechend
das fixiert mit den Gestängen hier das
wird eine lastanpassung gefahren und die
Fahrwiderstände aufzunehmen das ganze
wird mit einem ganz normalen Fahrer dem
dann ein Geschwindigkeitsprofil
vorgegeben wird dann in verschiedenen
Fahrzyklen durchgefahren und damit
können wir verschiedene
messkonzepte und messszenarien immer
wiederholen und miteinander vergleichen
diese Antriebseinheit ist funktionsfähig
es gibt bei dieser Konzept null
Emissionen als bremsabtriebe wir haben
auch bei den Reifen ablegen wir sehen
bei den ersten Daten dass wir auch da
ein Großteil entsprechend vermeiden
können dieses Auto ist ein absoluter
Prototyp in diesem Fahrzeug sind alle
Komponenten neu nicht nur der Antrieb
als Elektromotor Bremseinheit nicht nur
die Reifen Einhausung und entsprechende
aerodynamische Topologien sind hier neu
Gesellen sondern auch die komplette
elektrische Antriebseinheit und damit
wir dieses überhaupt testen können gibt
es nur zwei Möglichkeiten entweder wir
prüfen das ganze Fahrzeug und unsere
Komponenten hier auf dem Rollenprüfstand
oder auf einem Testgelände
[Musik]
[Musik]
verschiedene Teile des testgeländes
werden gebucht je nach versuche die wir
zu fahren haben die Messtechnik die wir
normalerweise im Labor haben haben wir
hier in das Fahrzeug integriert so dass
wir qualitativ hochwertige Ergebnisse
produzieren können zum Beispiel haben
wir hier es geschafft WTP nachzufahren
wir fahren verschiedene Kurse um auch
die
quer-emissionen also bei
Querbeschleunigungen zu bestimmen aber
auch verschiedene Bremsversuche werden
hier durchgeführt und dort auch zum
Beispiel den WTC Break im Detail
nachzufahren
[Musik]
was wir jetzt schon sagen können ist
dass wir auf jeden Fall bei den brems
Ableben im Vergleich zu der
konventionellen Bremse hier die Abtriebe
komplett das heißt auf Null fahren
können komplett vermeiden können bei den
Reifen haben unsere Kalkulationen
mindestens gezeigt dass wir bis zu in
etwa 50 km/h auch hier die abkriege
komplett vermeiden können und danach
nehmen die in etwa bisschen zu so dass
wir denken dass wir über einen WTC in
etwa in den Bereich 70 bis 80% kommen
werden
wir hoffen dass mit unserem guten
Ergebnissen hier der Demonstration
dieser entwickelten Prototypen und auch
dieser Komponenten soweit
Überzeugungsarbeit geleistet haben dass
wir die Möglichkeit haben mit unserer
Technologie dann auch irgendwann mal
erfolgreich in Serie und im Fahrzeug und
in der Mobilität anzukommen
