Abstract

The vehicle has a trunk (1) totally designed as an impeller profile, where required down force is produced by the impeller profile. A drive section (2) is arranged in a front area at steering- and drive wheels (5), where an aerodynamically designed camber (6) is arranged at a front base area of the vehicle. A deck-like bearing forces stabilizing profile (7) is arranged along the base area. An air inlet (3) is inserted in the front area.

Description

Die Erfindung betrifft einen Rennwagen mit ggf. freistehenden Rädern, insbesondere einen Formel 1 – Rennwagen.The The invention relates to a racing car with possibly freestanding wheels, in particular a Formula 1 racing car.

Rennwagen sind seit langem bekannt. Diese zeichnen sich u.a. durch komplexe aerodynamische Maßnahmen aus, um den Abtrieb (Downforce) des Rennfahrzeuges zu erhöhen. Insbesondere sind dies Spoiler an der Peripherien des Fahrzeuges.race car have been known for a long time. These are characterized i.a. through complex aerodynamic measures to increase the downforce of the race car. Especially These are spoilers on the peripheries of the vehicle.

Der effektive Wirkungsgrad dieser Maßnahmen führt allerdings nicht zur optimalen Aerodynamik.Of the However, effective efficiency of these measures does not lead to the optimum Aerodynamics.

Ziel der Erfindung ist es also, einen Rennwagen zu entwickeln, welcher bereits primär den effektiven Wirkungsgrad dieser Maßnahmen sehr deutlich erhöht.aim The invention is thus to develop a racing car, which already primary significantly increases the effective efficiency of these measures.

Prinzipielle Ausführungsbeispiele der Erfindung sind in den nachfolgenden 1 bis 4 exemplarisch beschreibend dargestellt und finden auch anhand der Patentansprüche Erläuterung.Basic embodiments of the invention are described in the following 1 to 4 illustrated by way of example descriptive and also based on the claims explanation.

1 (Seitenansicht), 2 (Draufsicht), 3 (Variante), 4 (Variante): 1 (Side view), 2 (Top view), 3 (Variant), 4 (Variant):

Kerngedanke ist der optimale Rumpf 1 des Rennfahrzeuges. Dieser ist in seiner Gesamtheit bereits als Mittel zum stark erhöhenden Abtrieb (Downforce) gestaltet; nämlich als Flügelprofil. Diese Maßnahme alleine erhöht bereits den Abtrieb um ca. 100%, so dass periphere Hilfsmaßnahmen wie Frontspoiler 4 und Heckspoiler 9 allenfalls als Option erforderlich sind. Dieses hat den entscheidenden Vorteil, dass die Spoiler dann kleiner ausfallen können (oder eben ganz entfallen können) und somit der gesamte Luftwiderstand stark reduziert werden kann; was wiederum den Treibstoffverbrauch sehr signifikant verringert.Core idea is the optimal hull 1 of the race car. This is in its entirety already designed as a means to greatly increasing downforce (downforce); namely as a sash profile. This measure alone increases the downforce by about 100%, so that peripheral relief measures such as front spoiler 4 and rear spoiler 9 if necessary as an option. This has the decisive advantage that the spoilers can then turn out to be smaller (or can be dispensed with completely) and thus the total air resistance can be greatly reduced; which in turn significantly reduces fuel consumption.

Durch die stark erhöhte Downforce kann der Rennwagen sehr viel schneller kurvenreiche Passagen der Rennstrecke passieren, mit dem Ergebnis, dass die Rundenzeiten drastisch verringert werden.By which greatly increased Downforce can make the race car much faster winding passages pass the racetrack, with the result that the lap times be drastically reduced.

Die erforderlichen Antriebsaggregate 2 belasten die erfindungsgemäß angeordneten Lenk- und Antriebsräder 5 in optimaler Art und Weise. Hierdurch bleibt das Fahrzeug beherrschbar, auch wenn einmal dessen Heck im Fahrverlauf ausbrechen sollte.The required drive units 2 load the steering and drive wheels arranged according to the invention 5 in an optimal way. As a result, the vehicle remains manageable, even if its rear should break out in the course of the road.

Ein Lufteinlass 3 im Frontbereich des Rennwagens sorgt für optimale Frischluftversorgung des Motors und ermöglicht sogar eine relativ starke Aufladung der Motor-Zylinder, so dass bei gleichem Hubraum auch die Motorleistung deutlich erhöht werden kann.An air intake 3 in the front of the race car provides optimum fresh air supply to the engine and even allows a relatively high charge the engine cylinders, so that at the same capacity and the engine power can be significantly increased.

Um einen möglichst tiefen Schwerpunkt zu erhalten, befindet sich am Bodenbereich des Fahrzeuges eine aerodynamisch vorteilhaft gestaltete Wölbung 6.In order to obtain the lowest possible center of gravity, located at the bottom of the vehicle an aerodynamically advantageous designed curvature 6 ,

Ein als Seitenflügel gestalteter Mittenbereich 7 des Fahrzeuges erhöht die Seitenwind-Unempfindlichkeit.A center wing designed as a side wing 7 of the vehicle increases the crosswind insensitivity.

Im hier gezeigten Ausführungsbeispiel verfügt der Rennwagen über konventionelle Bereifung 8.In the embodiment shown here, the race car has conventional tires 8th ,

Der Nackenbereich 10 des Fahrerbereiches 11 ist zusammen mit dem Windschutz 12 aerodynamisch ausgebildet und weist einen hier nicht näher beschriebenen Überrollschutz auf.The neck area 10 of the driver area 11 is together with the windbreak 12 Aerodynamically formed and has a rollover protection not described here in detail.

Insgesamt weist der erfindungsgemäß gestaltete Rennwagen außerdem und insbesondere eine drastisch erhöhte Insassensicherheit auf; bedingt durch die relativ großen Knautschzonen im Front- und Seitenbereich des Fahrzeuges. Auch der Heckbereich lässt sich noch zusätzlich um den Bereich 10 herum vorteilhaft mit hier nicht näher beschriebenen weiteren Sicherheitsmaßnahmen ausstatten.Overall, the race car designed according to the invention also and in particular a drastically increased occupant safety; due to the relatively large crumple zones in the front and side area of the vehicle. Also, the rear area is still in addition to the area 10 around advantageously equip with further security measures not described here.
