Abstract

When driving straight ahead the rolling resistance is taken up entirely by the main front (VM) and rear (HM) wheels arranged in tandem central to the vehicle longitudinal axis. Two auxiliary wheels (AML and AMR) are arranged off center to the vehicle transverse axis and these outer wheels (AML,AMR) are arranged higher than the main wheels and thus out of contact with the ground when driving straight. The wheels form a diamond pattern as arranged. Seating is also in balance in that the driver sits forward in the center and passenger etc sits in line behind or to the left and right outside.

Description

Kraftfahrzeuge, d.h. PKW fahren normalerweise auf 4 – mindestens auf 3 Rädern, welche ständig einen vollen Bodenkontakt haben. Bei diesen herkömmlichen Kraftfahrzeugen besteht ein wesentlicher Teil des Treibstoffverbrauchs durch den Rollwiderstand der 4 Räder (im Normalfall).Motor vehicles, i.e. Cars usually drive on 4 - at least on 3 wheels, which constantly have full contact with the ground. In these conventional motor vehicles a substantial part of the fuel consumption through the rolling resistance of the 4 wheels (normally).

1.1.

In der Neuerung des o.g. KFZ mit Haupt- und Nebenrädern sind zwei hintereinander laufende Räder (VM und HM) mittig zur Längsachse des Fahrzeugs angeordnet, während links und rechts die weiteren Räder (AML und AMR) mittig zur Querachse des Fahrzeugs mit einem geringen Höhenversatz angebracht sind.In the innovation of the above-mentioned vehicle with main and secondary wheels, there are two wheels running one behind the other ( VM and HM ) arranged centrally to the longitudinal axis of the vehicle, while the other wheels on the left and right ( AML and AMR ) are attached centrally to the transverse axis of the vehicle with a slight height offset.

D.h,, daß bei Geradeausfahrt die mittig zur Längsachse des Fahrzeugs angeordneten Räder (VM und HM) den Boden berühren, während die außen mittig zur Querachse des Fahrzeugs liegenden Räder (AML, und AMR) minimal über dem Boden schweben.Ie, that when driving straight ahead, the wheels arranged centrally to the longitudinal axis of the vehicle ( VM and HM ) touch the ground, while the wheels on the outside center of the transverse axis of the vehicle ( AML , and AMR ) hover minimally above the ground.

Die mittig zur Querachse des Fahrzeugs liegenden Räder (AML und AMR) berühren seitlich an der Außenseite des Fahrzeugs den Boden nur in der Kurvenfahrt zu Stabilisierung.The wheels in the center of the vehicle's transverse axis ( AML and AMR ) touch the ground on the side of the vehicle only for stabilization when cornering.

Die sich hier anbietende Karosserieform des KFZ ist in der Draufsicht in Form einer Raute mit der Anordnung der Räder und Sitzplätze in den Ecken.The body shape that offers itself here the top view of the vehicle is in the form of a diamond with the arrangement of the wheels and seats in the corners.

Hierdurch wird der Rollwiderstand halbiert.This will make the rolling resistance halved.

2.Second

Zusätzlich bietet sich die herkömmliche Karosserieform an, welche ebenfalls die Haupträder VM und HM angeordnet hat, wie in Pos. 1. Die Nebenräder sind außen jedoch nicht mittig, sondern vorne und hinten auf gleicher Höhe, wie die Haupträder, angeordnet. D.h. es gibt links das vordere Nebenrad AVL und das hintere Nebenrad AHL; rechts das vordere Nebenrad AVR und das hintere Nebenrad AHR. Alle Nebenräder haben wiederum die etwas höhere Anordnung gegenüber den Haupträdern mit dem gleichen Effekt, dass bei Geradeausfahrt der Rollwiderstand halbiert wird.In addition, there is the conventional body shape, which is also the main wheels VM and HM has arranged, as in item 1. However, the secondary wheels are not on the outside, but in the front and rear at the same height as the main wheels. Ie there is the front secondary wheel on the left AVL and the rear side wheel AHL ; on the right the front auxiliary wheel AVR and the rear side wheel AHR , All secondary wheels in turn have the somewhat higher arrangement compared to the main wheels with the same effect that the rolling resistance is halved when driving straight ahead.

Insgesamt:All in all:

Weiterhin wird neben der jeweiligen Karosserieform eine ausgeglichene Gewichtsverteilung nötig, was z.B. durch mittig angeordnete Sitze vorne und hinten möglich ist sowie einen dritten und vierten Sitz links und rechts. Ferner kann eine genaue Einstellung insbesondere für den Komfort durch verschiebbare Sitze erfolgen.In addition to the respective Body shape a balanced weight distribution necessary what e.g. is possible thanks to the centrally arranged seats at the front and rear and a third and fourth seat on the left and right. Furthermore, a precise setting especially for comfort by sliding Seats are made.
