Abstract

A vehicular hydraulic clutch has two wings (1) which slide back and forth along a line (2) into and out of recesses (3) so that they do not obstruct the throttle valves (5) fixed to the housing (4). The engine drives the rotor (7) by a shaft (6), while the housing is linked by another shaft to the gear. When the throttle valve is fully closed, there is no friction or juddering.

Description

Stand der Technik und Kritik am Stand der TechnikState of the art and criticism of the state of the art

Hydraulische Kupplungen werden zur Übertragung von großen Kräften bei stoßfreiem Anfah­ ren eingesetzt. Sie arbeiten verschleißfrei. Bei den bekannten hydraulischen Kupplungen ent­ stehen aber Verluste durch den Schlupf.Hydraulic clutches are used to transmit large forces with a bumpless start ren used. They work wear-free. In the known hydraulic couplings ent there are losses due to hatching.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, eine hydraulische Kupplung, die ohne Verluste arbeiten kann, darzustellen.The invention has for its object a hydraulic clutch without losses can work to represent.

Lösungsolution

Das in Abb. 1 beschriebene Aggregat stellt eine solche hydraulische Kupplung dar. Dieses Aggregat ähnelt einer Flügelzellenpumpe: Der Rotor 7 hat mindestens zwei verschiebbare, geführte Flügel 1, die entlang einer Linie 2 so in die Kammern 3 hinein geführt werden, daß sie das am Gehäuse 4 befestigte verstellbare Drosselventil 5 nicht berühren. Der Motor treibt über die Welle 6 den Rotor 7 an. Das Gehäuse ist über eine weitere Welle mit dem Getriebe verbunden. Schlupf tritt während des Anfahrens bei nicht vollständig geschlossenem Drossel­ ventil auf. Bei vollständig geschlossenem Drosselventil treten keine Reibung und kein Schlupf auf. Der Wirkungsgrad beträgt dann 100%. The unit described in Fig. 1 represents such a hydraulic clutch. This unit is similar to a vane pump: The rotor 7 has at least two displaceable, guided vanes 1 , which are guided along a line 2 into the chambers 3 so that they on the Do not touch the adjustable throttle valve 5 attached to the housing 4 . The motor drives the rotor 7 via the shaft 6 . The housing is connected to the gearbox via another shaft. Slip occurs during start-up when the throttle valve is not fully closed. With the throttle valve fully closed, there is no friction and no slippage. The efficiency is then 100%.

Vorteileadvantages

  • - Es treten kein Schlupf und keine Reibungen bei vollständig geschlossenem Drosselventil auf, wodurch der Wirkungsgrad gleich 1 wird.- There is no slippage and no friction when the throttle valve is fully closed on, making the efficiency equal to 1.
  • - Der Bau dieser hydraulischen Kupplung ist nicht so aufwendig wie der Bau der bekannten hydraulischen Kupplungen.- The construction of this hydraulic clutch is not as complex as the construction of the known hydraulic couplings.
  • - Das Drosselventil ermöglicht einen gesteuerten, stabilen Übergang zwischen den Zustän­ den "keine Kraftübertragung" (Schlupf =1) und "Übertragung der vollen Kraft" (Schlupf = 0).- The throttle valve enables a controlled, stable transition between the states the "no power transmission" (slip = 1) and "full power transmission" (Slip = 0).

Claims (1)

Hydraulische Kupplung dadurch gekennzeichnet, daß mindestens zwei verschiebbare, geführte Flügel (1) des Rotors (7) entlang einer Linie (2) so in die Kammern (3) hinein geführt werden, daß sie das am Gehäuse (4) befestigte verstellbare Drosselventil (5) nicht berühren, wobei der Motor über die Welle (6) den Rotor (7) antreibt, wäh­ rend das Gehäuse (4) über eine andere Welle mit dem Getriebe verbunden ist. Es kann auch das Gehäuse (4) vom Motor angetrieben werden, während der Rotor (7) mit dem Getriebe verbunden ist.Hydraulic clutch characterized in that at least two displaceable, guided vanes ( 1 ) of the rotor ( 7 ) are guided into the chambers ( 3 ) along a line ( 2 ) in such a way that they adjust the adjustable throttle valve ( 5 ) attached to the housing ( 4 ) ) do not touch, the motor driving the rotor ( 7 ) via the shaft ( 6 ), while the housing ( 4 ) is connected to the gearbox via another shaft. The housing ( 4 ) can also be driven by the motor while the rotor ( 7 ) is connected to the transmission.
