Abstract

The fast rotating mass (1) rotates about an axis (2) at right angles to the drive shaft axis (7). The mass is held in a frame (3) pivot mounted by two coaxial bearings (5, 5') coaxial to the drive shaft. Driving the retarder generates an opposing moment. The drive shaft drives the retarder via a coupling (6). The opposing moment is proportional to the inertia of the mass and product of the angular speeds of the mass and the drive.

Description

Stand der TechnikState of the art

Bei den bisher bekannten Retardern wird die unerwünschte Energie, z. B. bei der Talfahrt von schweren Fahrzeugen, ausschließlich direkt oder indirekt in Wärme umgewandelt.With the retarders known so far, the unwanted energy, e.g. B. in the descent of heavy vehicles, exclusively converted directly or indirectly into heat.

Direkt durch Reibung, indirekt durch Schaufelräder in Flüssig­ keit oder über Generatoren.Directly through friction, indirectly through paddle wheels in liquid speed or via generators.

Bei niedrigen Außen- oder Umgebungstemperaturen, ist die Abfüh­ rung der Wärme über besondere Kühlsysteme mit Gebläse verhält­ nismäßig unproblematisch. Jedoch bereits bei Umgebungstempera­ turen von ca. 20 Grad Celsius ist bei der Abführung der Retarder­ wärme jedes zusätzliche Wärmegrad, in der Umgebung, deutlich spürbar.At low outside or ambient temperatures, the discharge is heat through special cooling systems with blowers unproblematic. But already at ambient temperatures The temperature of the retarders is around 20 degrees Celsius warm any additional degree of warmth in the area noticeable.

Zur Lösung dieser Probleme wird mit vorliegender Erfindung eine Vorrichtung vorgeschlagen, die basierend auf dem Kreiselprinzip mit ihrem Gegenmoment, die unerwünschte Energie bzw. Drehbewe­ gung aufnimmt und unabhängig von der Umgebungstemperatur und Er­ wärmung beseitigt.To solve these problems with the present invention Device proposed based on the gyroscopic principle with its counter moment, the unwanted energy or rotation recording and regardless of the ambient temperature and Er heating removed.

Die bisher wohl bekannteste Anwendung des Kreiselprinzips dürfte wohl der Kreiselkompaß sein, dabei dient dieses allerdings nur zur Stabilisierung und nicht zur Aufnahme von Gegenmomenten. The most well-known application of the gyroscope principle to date is probably probably the gyrocompass, but this only serves for stabilization and not for taking up counter moments.  

Fig. I zeigt die erfindungsgemäße Vorrichtung.I shows the device according to the invention.

Ein kreisrunder Körper (1) dreht sich mit hoher Geschwindigkeit, in beliebiger Drehrichtung, als eine Art Schwungrad, um seine Mittelachse (2).A circular body ( 1 ) rotates at high speed, in any direction, as a kind of flywheel, around its central axis ( 2 ).

Die Lagerung von (2) befindet sich in einer Art Gabel (3), die mit ihrem Schaft (5) und oder (5′) in dem Lager (4) und oder (4′) drehbar gelagert ist.The storage of ( 2 ) is located in a kind of fork ( 3 ) which is rotatably mounted with its shaft ( 5 ) and or ( 5 ') in the bearing ( 4 ) and or ( 4 ').

Wird nun von der Welle (7) über die Kuppelung (6) eine Drehbe­ wegung, in beliebiger Richtung, auf den Schaft (5′) übertragen, so wird durch den, mit hoher Geschwindigkeit sich drehenden, Körper (1) dieser Drehbewegung ein Gegenmoment entgegengesetzt und somit die eingeleitete Drehbewegung erheblich gehemmt.If now from the shaft ( 7 ) via the coupling ( 6 ) a rotary movement, in any direction, is transmitted to the shaft ( 5 '), the body ( 1 ) rotating at high speed turns this rotary movement into a counter-moment opposite and thus significantly inhibited the initiated rotational movement.

Das Gegenmoment (MDg), das bei diesem Vorgang auftritt, ist pro­ portional zum Trägheitsmoment des rotierenden Körpers (1), seiner Winkelgeschwindigkeit w₁ und der Winkelgeschwindigkeit w₅, der Schäfte (5) und oder (5′), und ist in der FormelThe counter torque (MDg) that occurs in this process is proportional to the moment of inertia of the rotating body ( 1 ), its angular velocity w₁ and the angular velocity w₅, the shanks ( 5 ) and or ( 5 '), and is in the formula

MDg = J₁ w₁ * w₅MDg = J₁ w₁ * w₅

auszudrücken.express.

Der Antrieb des Körpers (1) kann auf verschiedene Arten erfolgen; Elektro-, Luft-, Hydraulikmotor oder direkt über einen fixen Außenzahnkranz, konzentrisch zu den Schäften (5) und oder (5′), auf welchem ein Ritzel sich abwälzt, das direkt mit der Mittel­ achse (2) verbunden ist und so abhängig von der Drehzahl des Schaftes (5) und oder (5′) den Körper (1) in eine Drehbewegung versetzt.The body ( 1 ) can be driven in various ways; Electric, air, hydraulic motor or directly via a fixed external ring gear, concentric to the shafts ( 5 ) and or ( 5 '), on which a pinion rolls, which is connected directly to the central axis ( 2 ) and thus depends on the speed of the shaft ( 5 ) and or ( 5 ') the body ( 1 ) in a rotational movement.

Auf diese Art und Weise ist es möglich einen Retarder bzw. Retar­ dergetriebe zu bauen, das in sich abgeschlossen ist und am Einbau­ ort, z. B. in einem Fahrzeug, keine zusätzlichen Leitungen, Wär­ metauscher oder Gebläse notwendig sind.In this way it is possible to use a retarder to build the gearbox that is self-contained and at the installation place, e.g. B. in a vehicle, no additional lines, heat Meters or blowers are necessary.
