Abstract

The hydraulic clutch (1) may have opposite-facing discs or vanes which may be curved or straight. They may be firmly fastened to the surface of the inner or outer cylinder. The discs may be moved to interrupt the power transmission from the inner to the outer cylinder. Alternatively the power-transmitting medium may be drained from the space between the cylinders.

Description

Bei einer hydraulischen Kraftübertragung z. B. durch einen Wandler besteht ein Energieverlust, der besonders am Anfang der Kraftübertragung einen großen Wert aufweist.With a hydraulic power transmission z. B. by a converter Energy loss, which is of great value especially at the beginning of power transmission having.

Durch die im Patentanspruch aufgeführten Merkmale entstehen viel geringere Energieverluste.The features listed in the patent claim result in much fewer Energy losses.

Diese Kupplung besteht aus zwei ineinander liegenden Zylindern, deren Zwischenraum mit Öl gefüllt ist. Die Zylinder besitzen entgegengerichtete gekrümmte Lamellen. Dreht sich der innere Zylinder, so wird auch der äußere gedreht (s. Abb. 4, 5, 6).This clutch consists of two cylinders lying one inside the other, the space between which is filled with oil. The cylinders have opposing curved fins. If the inner cylinder rotates, the outer cylinder also rotates (see Fig. 4, 5, 6).

Die hier ausgeübten Kräfte sind:The forces exerted here are:

  • 1. Fliehkraft der Öltropfen1. Centrifugal force of the oil drops
  • 2. Impulskraft2. Impulse power
  • 3. Adhäsion (Widerstand durch Spannungskraft der Ölmoleküle, die der Scherkraft zwischen inneren und äußeren Lamellen entgegenwirkt.)3. Adhesion (resistance due to the tensile force of the oil molecules, that of the shear force counteracts between inner and outer slats.)

Es ist hierbei sinnvoller, Lamellen unterschiedlicher Länge zu bauen, weil sich so die Fläche zwischen inneren und äußeren Lamellen vergrößert. Somit wird mehr Platz gespart und der Ölstrom besser gerichtet (vgl. Abb. 4 und Abb. 5).It makes more sense to build slats of different lengths because this increases the area between the inner and outer slats. This saves more space and directs the oil flow better (see Fig. 4 and Fig. 5).

Die Kupplung kann auf drei verschiedenen Wegen ausgekuppelt werden:The clutch can be disengaged in three different ways:

  • a) Indem die Lamellen auf dem inneren (oder äußeren!) Zylinder um eine Achse gedreht werden, so daß sie nicht mehr gegen die Strömungen stehen (s. Abb. 1).a) By rotating the fins on the inner (or outer!) cylinder around an axis so that they are no longer against the currents (see Fig. 1).
  • b) Indem die Lamellen herunter geschoben werden (s. Abb. 2 und 3).b) By sliding the slats down (see Fig. 2 and 3).
  • c) Indem das Öl herausgepumpt wird.c) By pumping out the oil.

Je nach Wunsch kann man einen dieser Wege wählen. Es ist aber dabei zu beachten, daß durch Drehen der Lamellen, je nach Winkelgrad, unterschiedliche Kräfte auf den äußeren Zylinder ausgeübt werden kann. Dies hat den Vorteil, daß nicht nur die ganze Kraft des Motors, sondern auch ein Teil dieser Kraft übertragen werden kann. (z. B. wenn der Fahrer im Stau ganz langsam fahren möchte.)
Natürlich kann ab einer bestimmten Drehzahl die Kraftübertragung vom inneren auf den äußeren Zylinder durch einen Schaltring oder auf andere Weise mechanisch erfolgen.Depending on your wishes, you can choose one of these ways. It should be noted, however, that by rotating the fins, depending on the degree of angle, different forces can be exerted on the outer cylinder. This has the advantage that not only the entire power of the engine but also part of this power can be transmitted. (e.g. if the driver wants to drive very slowly in a traffic jam.)
From a certain speed, the transmission of force from the inner to the outer cylinder can of course take place mechanically by means of a switching ring or in another way.

Hierfür kann z. B. wie im Abb. 7 dargestellt die Kraft vom inneren auf den äußeren Zylinder durch kleine Kugeln, die wiederum durch einen magnetischen Kegelstumpf nach oben oder unten bewegt werden, erfolgen.For this, e.g. B. as shown in Fig. 7, the force from the inner to the outer cylinder by small balls, which in turn are moved up or down by a magnetic truncated cone.

Hydraulische Kupplung; gekennzeichnet durch zwei ineinander liegende Zylinder, deren Zwischenraum mit geeigneter Flüssigkeit gefüllt ist, mit entgegengerichteten Lamellen welche gekrümmt oder nicht gekrümmt sein können, wobei die Lamellen, die auf dem inneren (bzw. äußeren) Zylinder liegen, bewegbar sein können, um die Kraftübertragung von dem inneren Zylinder auf den äußeren Zylinder zu unterbrechen oder dies durch Entzug des kraftübertragenden Mediums erfüllen.Hydraulic clutch; characterized by two nested cylinders, the space between which is filled with suitable liquid, with opposing fins which can be curved or not, the fins lying on the inner (or outer) cylinder can be movable to transmit the force from interrupt the inner cylinder to the outer cylinder or do so by withdrawing the force-transmitting medium.
