Abstract

The continuously variable transmission is a gear mechanism in which there is frictional connection at all times over the entire control range from clockwise rotation, via the stationary condition, to anticlockwise rotation. The control range according to the diagram in the patent drawing is from i = 6.4, via the stationary condition, to i = -0.6.

Description

Die Erfindung betrifft ein stufenlos regelbares Zahnradgetriebe.The invention relates to a continuously variable Gear transmission.

Bekanntgeworden sind Regelgetriebe als Reibradgetrie­ be, Keilriemengetriebe, Kettengetriebe, hydrostatische Getrie­ be und auch Zahnradgetriebe, die aber nur begrenzt zur Anwend­ ung gekommen sind. Die wesentlichen Nachteile dieser Getrie­ be sind:Regulating transmissions have become known as friction wheel transmissions be, V-belt transmission, chain transmission, hydrostatic transmission be and also gear transmissions, which are only of limited use have come. The main disadvantages of this gear are:

  • a) schlechter Wirkungsgrad,a) poor efficiency,
  • b) begrenzte Leistungsübertragung,b) limited power transfer,
  • c) kleiner Regelbereich,c) small control range,
  • d) ungünstige Bauform.d) unfavorable design.

Das Getriebe der Erfindung vermeidet diese Nachteile und unterscheidet sich von allen bekanntgewordenen Getrie­ ben dadurch, daß der Drehzahlregelbereich vom Linkslauf über den Stillstand bis zum maximalen Rechtslauf reicht.The transmission of the invention avoids these disadvantages and differs from all known transmissions ben in that the speed control range from counterclockwise rotation the standstill extends to the maximum clockwise rotation.

Zu den Abb. 1, 2, 3, 4, 5To Figs. 1, 2, 3, 4, 5

Die Abb. 1 zeigt einen Schnitt durch das Getriebe, bei dem das Schwenkgehäuse in die Zeichenebene gelegt ist und bei (1) das Verstellgetriebe als Alternative. Fig. 1 shows a section through the gearbox with the swivel housing placed in the plane of the drawing and with ( 1 ) the adjustment gear as an alternative.

Die Drehzahländerung wird durch Verstellen des Schwenkgehäuses um maximal 170° dadurch erzielt, daß das Kegelrad (16), das mit dem Hohlrad (6) fest verbunden ist, durch das umlaufende Kegelrad (16) im Stillstand gehalten wird und das Sonnenrad (7), das über eine Mittelachse mit dem Gehäuse (5) fest verbunden ist, eine Umdrehung ausführen kann. Bei der Stellung nach Abb. (4) ist es umgekehrt, da führt das Hohlrad (6) eine entgegengesetzte Umdrehung aus und das Sonnenrad (7) steht still.The speed change is achieved by adjusting the swivel housing by a maximum of 170 ° in that the bevel gear ( 16 ), which is fixedly connected to the ring gear ( 6 ), is held at a standstill by the rotating bevel gear ( 16 ) and the sun gear ( 7 ), which is firmly connected to the housing ( 5 ) via a central axis, can make one revolution. In the position according to Fig. (4) it is the other way round, since the ring gear ( 6 ) makes an opposite turn and the sun gear ( 7 ) stands still.

Die Abb. 2 zeigt das Stirnraddifferential mit dem Hohlrad (6), dem Sonnenrad (7), den Planetenrädern (15) und den Steg (17). Fig. 2 shows the spur gear differential with the ring gear ( 6 ), the sun gear ( 7 ), the planet gears ( 15 ) and the web ( 17 ).

Die Abb. 3 zeigt den um 90° gedrehten Rotor mit dem um 5° verstellten Schwenkgehäuse im Schnitt, der Grund­ stellung für den Linkslauf. Bei der kleinen Schwenkung wird das Hohlrad (6) im Stillstand gehalten, und das Sonnenrad (7) führt mit dem Rotor (4) eine Umdrehung aus.
Ø Teil (6)=36 mm, Ø Teil (7)=24 mm. Fig. 3 shows the rotor rotated by 90 ° with the swivel housing adjusted by 5 ° on average, the basic position for counterclockwise rotation. With the small swiveling, the ring gear ( 6 ) is held at a standstill and the sun gear ( 7 ) rotates with the rotor ( 4 ).
Ø part ( 6 ) = 36 mm, Ø part ( 7 ) = 24 mm.

i/steg==0,4 i / web == 0.4

das weiterleitende Kegelrad (8)=Ø78, Rad (9)=39 mmthe forwarding bevel gear ( 8 ) = Ø78, gear ( 9 ) = 39 mm

i/==2-2 · 0,4=0,8 i / == 2-2.0.4 = 0.8

Die Endstufe der Räder (10) und (12) ist ebenfalls i=2
i/=2 · -0,8=-1,6 plus 1 Rechtsdrehung
i/nach Abb. 3=-0,6The final stage of wheels ( 10 ) and ( 12 ) is also i = 2
i / = 2 · -0.8 = -1.6 plus 1 turn to the right
i / according to Fig. 3 = -0.6

Die Abb. 4 zeigt die Mittelstellung bei der das Sonnenrad (7) still steht und das Hohrad (6) eine Umdrehung ausführt. Fig. 4 shows the middle position at which the sun wheel ( 7 ) stands still and the hoist wheel ( 6 ) makes one revolution.

i/steg==0,6 i / web == 0.6

i/der nächsten Stufen ist wieder 2+2=4
i/Abb. 4=4 · 0,6=2,4+1 Umdrehung=3,4 i / the next level is 2 + 2 = 4 again
i / Fig. 4 = 4 · 0.6 = 2.4 + 1 turn = 3.4
