Description
Die vorliegende Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruches 1, ein Getriebe gemäß dem Oberbegriff des Patentanspruches 6 sowie ein Fahrzeug mit einem derartigen Getriebe gemäß den Merkmalen des Patentanspruches 16.The present invention relates to a method according to the preamble of claim 1, a transmission according to the preamble of
Aus der
Aufgabe der Erfindung ist es, ein Verfahren zum zugkraftunterbrechungsfreien Schalten eines Getriebes anzugeben bzw. ein entsprechendes Getriebe sowie ein Fahrzeug mit einem derartigen Getriebe zu schaffen, das einfach durchführbar bzw. aufgebaut ist und insbesondere für Fahrzeuge mit Elektroantrieb geeignet ist.The object of the invention is to provide a method for traction-free switching of a transmission or to provide a corresponding transmission and a vehicle with such a transmission, which is easy to carry out or built and is particularly suitable for vehicles with electric drive.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 bzw. 6, bzw. 16 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of
Ausgangspunkt der Erfindung ist ein Getriebe, welches zugkraftunterbrechungsfrei von einem ersten Getriebegang in einen zweiten Getriebegang schaltbar ist, wobei das Getriebe ein erstes Schaltelement und ein zweites Schaltelement und zum Betätigen der Schaltelemente eine erste Betätigungseinrichtung und eine zweite Betätigungseinrichtung aufweist.The starting point of the invention is a transmission which is traction-interruption-free switchable from a first gear to a second gear, said transmission having a first switching element and a second switching element and for actuating the switching elements, a first actuator and a second actuator.
Der Kern der Erfindung (und ein zentraler Unterschied gegenüber der eingangs genannten
Während eines Schaltvorgangs, bei dem das Getriebe von einem ersten Getriebegang in einen zweiten Getriebegang umgeschaltet wird, wird das erste Schaltelement und zeitlich überschneidend dazu, das zweite Schaltelement betätigt. Das erste Schaltelement ist durch ein erstes Druckelement und das zweite Schaltelement durch ein zweites Druckelement betätigbar. Die Druckelemente sind in einer Axialrichtung verschieblich angeordnet. D. h. durch Verschieben der Druckelemente in Axialrichtung können die Schaltelemente geöffnet bzw. geschlossen werden.During a switching operation in which the transmission is switched from a first gear to a second gear, the first switching element and temporally overlapping thereto, the second switching element is actuated. The first switching element can be actuated by a first pressure element and the second switching element by a second pressure element. The pressure elements are arranged displaceably in an axial direction. Ie. by shifting the pressure elements in the axial direction, the switching elements can be opened or closed.
Betätigt werden die Betätigungseinrichtungen durch Aktuatoren, bzw. durch jeweils eine Aktuatorik. Denkbar ist z. B. eine hydraulische Betätigung. Alternativ dazu können die Betätigungseinrichtungen auch elektromechanisch ausgebildet sein. Bei den Aktuatoren kann es sich beispielsweise um Drehaktuatoren handeln. Insbesondere kann vorgesehen sein, dass mindestens eine der Betätigungseinrichtungen mindestens eine Kugel-/Rampenanordnung aufweist, mittels der ein von einem Drehaktuator erzeugtes Drehmoment in eine Axialbewegung mindestens eines der Schaltelemente umgesetzt wird.The actuators are actuated by actuators, or by an actuator in each case. It is conceivable z. B. a hydraulic actuator. Alternatively, the actuators may also be electromechanical. The actuators may, for example, be rotary actuators. In particular, it can be provided that at least one of the actuating devices has at least one ball / ramp arrangement, by means of which a torque generated by a rotary actuator is converted into an axial movement of at least one of the switching elements.
Es kann vorgesehen sein, dass ein erster Drehaktuator über eine erste Zahnradstufe mit der ersten Betätigungseinrichtung gekoppelt ist. Ein zweiter Drehaktor kann über eine zweite Zahnradstufe mit der ersten Betätigungseinrichtung und über eine dritte Zahnradstufe mit der zweiten Betätigungseinrichtung gekoppelt sein.It can be provided that a first rotary actuator is coupled to the first actuating device via a first gear stage. A second rotary actuator may be coupled to the first actuating device via a second gear stage and to the second actuating device via a third gear stage.
Nach einer Weiterbildung der Erfindung weist die mindestens eine Kugel-/Rampenanordnung mit mindestens einer sich in einer Umfangsrichtung erstreckende Kurvenbahn auf, wobei sich ein Höhenprofil der Kurvenbahnen, in Umfangsrichtung betrachtet, verändert. Durch Verdrehen einer die Kurvenbahn enthaltenden bzw. aufweisenden Scheibe o. ä. kann somit eine Drehbewegung in eine axiale Verstellbewegung umgesetzt werden.According to a development of the invention, the at least one ball / ramp arrangement has at least one curved path extending in a circumferential direction, wherein a height profile of the curved paths, viewed in the circumferential direction, changes. By rotating a cam disc containing or having disc o. Ä. Thus, a rotational movement can be converted into an axial adjustment movement.
Bei den Schaltelementen handelt es sich vorzugsweise um Reibschaltelemente, insbesondere um Reibkupplungen oder Reibbremsen. Jedes der Schaltelemente kann durch mehrere Lamellen (Lamellenkupplungen bzw. Lamellenbremse) gebildet sein.The shift elements are preferably friction shift elements, in particular friction clutches or friction brakes. Each of the switching elements can be formed by a plurality of fins (multi-plate clutches or multi-disc brake).
Nach einer Weiterbildung der Erfindung kann vorgesehen sein (jedoch nicht zwingend erforderlich), dass mindestens eine der Betätigungseinrichtungen bzw. mindestens einer der damit gekoppelten Drehaktuatoren selbsthemmend ist. „Selbsthemmend” bedeutet in diesem Zusammenhang, dass, wenn die Betätigungseinrichtungen „energielos werden” die Schaltelemente ihren momentanen Schaltzustand beibehalten, d. h. nicht selbsttätig öffnen bzw. in einen anderen Schaltzustand umschalten.According to a development of the invention can be provided (but not mandatory), that at least one of the actuators or at least one of the coupled rotary actuators is self-locking. "Self-locking" in this context means that when the actuators become "de-energized", the switching elements maintain their current switching state, i. H. do not open automatically or switch to another switching state.
Ein derartiges Getriebe ist insbesondere für Fahrzeuge mit Elektroantrieb, insbesondere für reine Elektrofahrzeuge, geeignet. Es kann vorgesehen sein, dass ein derartiges Fahrzeug nur zwei Gänge aufweist. Ein derartiges Fahrzeug weist somit einen Fahrzeugvortrieb erzeugenden Elektromotor auf, der über das Getriebe und z. B. ein Differential mit Antriebsrädern des Fahrzeugs gekoppelt ist.Such a transmission is particularly suitable for vehicles with electric drive, especially for pure electric vehicles. It can be provided that such a vehicle has only two gears. Such a vehicle thus has a vehicle propulsion generating electric motor, via the transmission and z. B. a differential is coupled to drive wheels of the vehicle.
