Patentantrag P 25 14 738.0 Benennung: Hydro-Drehmomentkupplung Anwendungsgebiet: Für den Kraftwagenantrieb als Kupplun und gleichzeitig Is brehzahl-Untersetzungselement.Patent application P 25 14 738.0 Designation: Hydro torque coupling Area of application: For the motor vehicle drive as a clutch and at the same time is speed reduction element.
Jedoch auch für andere Antriebe geeignet.However, it is also suitable for other drives.
Das Kupplungsdrehmoment kann dem Motordrehmoment angepaßt werden bei gleichzeitiger großer Eingangsdrehzahl und kleiner Ausgangsdrehzahl.The clutch torque can be adapted to the engine torque at simultaneous high input speed and low output speed.
Zweck: In diesem Antriebselement sind auf einfachste weise Kupplung un Drehzahluntersetzung in einem Bauelement vereint.Purpose: In this drive element there is a coupling in the simplest possible way un speed reduction combined in one component.
Die Herstellung ist wesentlich einfacher und billiger wie ein herkömmliches Schaltgetriebe.The production is much easier and cheaper than a conventional one Manual transmission.
Lösung: Über einen Hydr.-Ringzylinder wird eine Kupplungshälfte,auf der außen Kepelrollen laufen,in die zweite Kupplungshälfte gedrückt.Solution: A coupling half is opened via a hydraulic ring cylinder of the Kepel rollers running on the outside, pressed into the second half of the coupling.
Dadurch entsteht zwischen Kupplungshälfte und Kegelrolle ein Rollwiederstand.This creates a rolling resistance between the coupling half and the tapered roller.
Dieser Rollwiederstand bestimmt das übertragbare Drehmoment.This rolling resistance determines the torque that can be transmitted.
Es kann somit das Drehmoment,durch mehr oder weniger starke Anpreßkraft der Kegelrollen auf die Laufflächen,eingestellt werden.It can thus increase the torque, through more or less strong contact pressure the tapered rollers on the running surfaces.
Die Laufflächen auf denen die Kegelrollen laufen können aus Hartgummi oder Nylon bestehen.The running surfaces on which the tapered rollers run can be made of hard rubber or nylon.
Ein Auskuppeln wird durch Druckentlastung erreicht.A disengagement is achieved by relieving the pressure.
Erzielbare Vorteile: Kupplung und Drehzahluntersetzung in einem Bauelement, Einfache und billige Herstellung.Achievable advantages: clutch and speed reduction in one component, Simple and cheap to manufacture.
Das Kupplungs-Drehmoment kann dem Motor-Drehmoment angepaßt werden, dadurch gleichmäßiges hochlaufen des Motors möglich.The clutch torque can be adapted to the engine torque, this enables the motor to run up evenly.
RoIlwiederstand: Infolge der Anpreßkraft drückt sich die Rolle in die Unterlage ein.Roll resistance: As a result of the contact pressure, the roller is pushed in the document.
Dadurch muß die Rolle ständig um die Kante (D) gekippt werden.This means that the roll has to be constantly tilted around the edge (D).
Siehe hierzu Blatt Nr.7 Daraus ergibt sich: Summe aller Momente um (D) gleich Null.See sheet no.7 This results in: Sum of all moments um (D) equals zero.
F. 1 - f = 0 daraus wird: f Rollkraft F = Rechenbeispiel: Rollkreisdurchmesser = 24Ommm mittlerer Kegelrollendurchm. = 10 mm Anzahl der Kegelrollen = 30 Stuck.F. 1 - f = 0 from this: f rolling force F = Sample calculation: Rolling circle diameter = 24Ommm mean tapered roller diameter. = 10 mm number of tapered rollers = 30 pieces.
Anpreßkraft P pro Kegel-4Rolle mit 20 kp angenommen.Contact pressure P per 4-cone roller assumed to be 20 kp.
Der Kipphebelarm soll f = 1 mm betragen.The rocker arm should be f = 1 mm.
Daraus ergibt sich die übertragbare Kraft pro Kegelrolle mit: F = 20(kp). ####### = 4 (kp) pro Kegelrolle.This results in the transferable force per tapered roller with: F = 20 (kp). ####### = 4 (kp) per tapered roller.
Daraus ergibt sich ein Kuplungs-Drehmoment von M (d)t r (kpm) P = 4.30 = 120kp r = 0, 12(m) M (d) =120(kp) 0,12(m) = 14,4 (mkp) Dies entspricht einer übertragbaren Leistung bei einer Motordrehzahl von n = 3500 (Umdr.pro min.) M (d)'n = 716 (Ps) 14,4(mkp) 3 500(Umdr. pro min.) P = 716 P = 75 (Ps)This results in a coupling torque of M (d) t r (kpm) P = 4.30 = 120kp r = 0.12 (m) M (d) = 120 (kp) 0.12 (m) = 14.4 (mkp) This corresponds to a transmittable power at an engine speed of n = 3500 (revs per min.) M (d) 'n = 716 (Ps) 14.4 (mkp) 3 500 (revs. Per min.) P = 716 P = 75 (Ps)
