Description

Die Erfindung betrifft einen hydraulischen Getriebeaktuator nach den Merkmalen den Oberbegriffs des Patentanspruchs 1.The invention relates to a hydraulic transmission actuator according to the features of the preamble of patent claim 1.

Hydraulische Getriebeaktuatoren werden beispielsweise bei automatisierten Schaltgetrieben für die Synchronisierung der Getriebegänge eingesetzt (siehe beispielsweise Johannes Lohmann, Zahnradgetriebe, 2. Auflage, Seite 156ff.).Hydraulic transmission actuators are used for example in automated manual transmissions for the synchronization of the gears (see, for example, Johannes Lohmann, gear transmission, 2nd edition, page 156ff.).

Bei gattungsgemäßen hydraulischen Getriebeaktuatoren wird der von zwei Druckräumen begrenzte Stellkolben durch eine entsprechende Druckbeaufschlagung jeweils nach links oder rechts verschoben, wobei zur Abdichtung der beiden Druckräume am Stellkolben ein Dichtungselement vorgesehen ist. Beim Einsatz der hydraulischen Getriebeaktuatoren müssen beispielsweise bei der Synchronisierung der Getriebezahnräder hohe Stellkräfte aufgebracht werden, die eine zuverlässige und dauerhafte Abdichtung bzw. Trennung der beiden Druckräume erforderlich machen. Aufgabe der Erfindung ist es daher, die Abdichtung der beiden Druckräume im Bereich des Stellkolbens zu verbessern.In generic hydraulic transmission actuators limited by two pressure chambers actuator piston is displaced by a respective pressurization in each case to the left or right, wherein a sealing element is provided for sealing the two pressure chambers on the actuating piston. When using the hydraulic transmission actuators, for example, in the synchronization of the transmission gears high actuating forces must be applied, which make a reliable and permanent sealing or separation of the two pressure chambers required. The object of the invention is therefore to improve the sealing of the two pressure chambers in the region of the actuating piston.

Aus der US 2955667 ist eine hydraulische Lenkhilfe beschrieben, welche eine hydraulische Zylindereinheit aufweist, in der in einem Zylindergehäuseabschnitt der Durchmesser des Zylindergehäuses gegenüber der Zylinderinnenwand im mittleren Bereich des Zylinders zu Erzielung einer zusätzlichen Reibung zwischen dem Zylindergehäuse und dem Kolben reduziert ist.From the US 2955667 a hydraulic power steering is described, which has a hydraulic cylinder unit in which is reduced in a cylinder housing portion, the diameter of the cylinder housing relative to the cylinder inner wall in the central region of the cylinder to achieve additional friction between the cylinder housing and the piston.

De Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.

Zur Erhöhung der radialen Anpresskraft des Dichtungselementes gegenüber der Zylinderinnenwand ist der Durchmesser des Hydraulikzylinders auf vorteilhafte Art und Weise in einem Bereich, in dem hohe Stellkräfte auf den Stellkolben wirken, lokal reduziert.To increase the radial contact pressure of the sealing element relative to the cylinder inner wall, the diameter of the hydraulic cylinder in an advantageous manner and Mode locally reduced in an area in which high actuating forces act on the actuator piston.

Durch die in den Unteransprüchen angegebenen Merkmale sind weitere vorteilhafte Ausgestaltungen und Weiterbildungen des hydraulischen Getriebeaktuator möglich.The features specified in the dependent claims further advantageous embodiments and refinements of the hydraulic Getriebeaktuator are possible.

Der Durchmesser des Hydraulikzylinders ist in einer von der Mittellage des Stellkolbens im Hydraulikzylinder abweichenden linken und rechten Wirkstellung gegenüber dem Durchmesser des Hydraulikzylinders bei Mittellage des Stellkolbens reduziert. Damit wird in beiden Wirkstellungen des Stellkolbens eine höhere Anpresskraft des Dichtungselements gegenüber der Zylinderinnenwand erreicht.The diameter of the hydraulic cylinder is in a deviating from the central position of the actuating piston in the hydraulic cylinder left and right operative position relative to the Reduced diameter of the hydraulic cylinder at central position of the actuating piston. Thus, a higher contact pressure of the sealing element relative to the cylinder inner wall is achieved in both operative positions of the actuating piston.

Nach dem Durchfahren beider Wirkstellungen erweitert sich der Durchmesser des Hydraulikzylinders, so dass die Anpresskraft des Dichtungselements gegenüber der Zylinderinnenwand an die reduzierten Stellkräfte angepasst ist.After passing through both operative positions, the diameter of the hydraulic cylinder expands, so that the contact pressure of the sealing element with respect to the cylinder inner wall is adapted to the reduced actuating forces.

Dadurch, dass der Stellkolben und damit auch das Zylindergehäuse gestuft ausgebildet sind, kann in einem ersten Verstellweg mit kleinem Kolbendurchmesser eine hohe Verstellgeschwindigkeit mit geringer Reibung erreicht werden, während in den beiden Wirkstellungen die Hydraulikkraft auf den großen Kolbendurchmesser wirkt, so dass eine höhere radiale Anpresskraft des Dichtungselementes gegen die Zylindergehäuseinnenwand erzeugbar ist.Characterized in that the adjusting piston and thus the cylinder housing are stepped, a high adjustment can be achieved with low friction in a first adjustment with a small piston diameter, while in the two operative positions, the hydraulic force acts on the large piston diameter, so that a higher radial contact pressure of the sealing element against the cylinder housing inner wall can be generated.

Der hydraulische Getriebeaktuator ist insbesondere als Stellelement für die Synchronisierung von Getriebegängen bei automatisierten Schaltgetrieben einsetzbar.The hydraulic transmission actuator can be used in particular as an adjusting element for the synchronization of transmission gears in automated manual transmissions.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im nachfolgenden näher beschrieben.An embodiment of the invention is illustrated in the drawing and will be described in more detail below.

Der als Stellelement zum Synchronisieren bzw. für einen Gangwechsel bei einem automatisierten Schaltgetriebe vorzugsweise einsetzbare Getriebeaktuator 2 weist ein Zylindergehäuse 4 auf, in dessen Zylinderraum 6 ein doppelt wirkender Stellkolben 8 längsverschieblich aufgenommen ist. Der Stellkolben 8 ist dabei als Stufenkolben ausgebildet und weist einen im Zylinderraum 6 geführten Zentralkolben 8a auf, an den sich ein linkes und rechtes Stellkolbenelement 8b und 8c anschließen. Der Zentralkolben 8a weist auf seiner Umfangsfläche einen Dichtungsring 10 auf, der die beiden durch den Zentralkolben 8a abgetrennten Zylinderteilräume 6a und 6b voneinander abdichtet. Die beiden gegenüber dem Zentralkolben 8a im Durchmesser reduzierten Stellkolbenelemente 8b und 8c sind in einem linken und rechten Zylindergehäuseteil 4b und 4c längsverschieblich geführt. Am linken und rechten Stellkolbenelement 8b bzw. 8c ist jeweils eine Kolbenstange 12 und 14 befestigt, die am Ende des linken und rechten Zylindergehäuseteils 4b und 4c nach außen hin durch jeweils eine Dichtung 16 und 18 abgedichtet ist.The preferably used as an adjusting element for synchronizing or for a gear change in an automated transmission transmission actuator 2 has a cylinder housing 4, in the cylinder chamber 6, a double-acting actuator piston 8 is received longitudinally displaceable. The adjusting piston 8 is designed as a stepped piston and has a guided in the cylinder chamber 6 central piston 8a, followed by a left and right actuating piston element 8b and 8c. The central piston 8a has on its peripheral surface a sealing ring 10, which seals the two separated by the central piston 8a cylinder part spaces 6a and 6b from each other. The two adjusting piston elements 8b and 8c reduced in diameter relative to the central piston 8a are guided longitudinally displaceably in a left and a right cylinder housing part 4b and 4c. On the left and right actuating piston element 8b and 8c, respectively, a piston rod 12 and 14 is fixed, which is at the end of the left and right cylinder housing part 4b and 4c outwardly sealed by a respective seal 16 and 18.

An die sich im linken und rechten Zylindergehäuseteil 4b und 4c ausbildenden Teilräume 20 und 22 ist jeweils eine Hydraulikleitung 24 und 26 angeschlossen, über die die beiden Teilräume 20 und 22 mit Hydrauliköl beaufschlagbar sind.At the forming in the left and right cylinder housing part 4b and 4c subspaces 20 and 22 each have a hydraulic line 24 and 26 is connected, via which the two subspaces 20 and 22 are acted upon with hydraulic oil.

Wie aus Fig. 1 ersichtlich, ist der Durchmesser des zentralen Zylindergehäuseteils 4a über seine Länge I nicht einheitlich ausgebildet, sondern weist in der Mittellage bzw. Mittelstellung des Zentralkolbens 8a sowie an seinem linken bzw. rechten Ende, das den Endlagen des Stellkolbens 8 entspricht, einen maximalen Durchmesser D1 auf, während sich der Durchmesser vom linken bzw. rechten Ende und von der Mittelstellung des Zentralkolbens 8a ausgehend stetig verringert. An den beiden in Fig. 1 gestrichelt dargestellten Positionen W1 und W2 weist der Durchmesser des zentralen Zylindergehäuseteils 4a mit seinem Durchmesser D2 jeweils ein Minimum auf. Erreicht der Stellkolben einer diesen beiden Wirkpositionen W1 oder W2 (siehe z. B. Fig. 3), so ist die radiale Anpresskraft des Dichtungsringes 10 gegenüber der Zylinderinnenwand am größten.How out Fig. 1 can be seen, the diameter of the central cylinder housing part 4a is not uniform over its length I, but has in the central position or center position of the central piston 8a and at its left or right end corresponding to the end positions of the actuating piston 8, a maximum diameter D1 while the diameter decreases steadily from the left and right ends and from the center position of the center piston 8a. At the two in Fig. 1 Dotted positions shown W1 and W2, the diameter of the central cylinder housing part 4a with its diameter D2 each have a minimum. If the actuating piston reaches one of these two effective positions W1 or W2 (see, for example, FIG. Fig. 3 ), the radial contact pressure of the sealing ring 10 with respect to the cylinder inner wall is greatest.

Wenn der hydraulische Getriebeaktuator als Stellelement für den Gangwechsel in einem automatisierten Schaltgetriebe verwendet wird, zu dem beispielsweise auch die sogenannten Doppelkupplungsgetriebe gehören, stellt sich seine Funktion wie folgt dar:When the hydraulic transmission actuator is used as an actuator for the gear change in an automated manual transmission, which includes, for example, the so-called dual-clutch transmission, its function is as follows:

Die Mittellage des Zentralkolbens 8a entspricht der Position Neutral N, während die linke Endlage des Stellkolbens 8 bspw. einem eingelegten Gang 1 und die rechte Endlage des Stellkolbens 8 bspw. einem eingelegten Gang G3 entspricht. Wie allgemein bekannt, ist für den Gangwechsel die Herstellung einer drehfesten Verbindung zwischen einer drehfest aber längsverschieblich auf der Getriebewelle angeordneten Schiebemuffeneinheit und einem der Schiebemuffeneinheit zugeordneten Loszahnrad erforderlich. Zum Angleichen der unterschiedlichen Drehgeschwindigkeiten von Getriebewelle und Loszahnrad ist eine zwischen Schiebemuffeneinheit und Loszahnrad angeordnete Synchronisiereinheit, z. B. nach Borg - Warner, erforderlich. Im nachfolgenden wird die Synchronisierung bzw. der Gangwechsel von der Position N zum ungeraden Gang G3 anhand der Figuren 1 bis 5 näher erläutert. Durch eine Druckbeaufschlagung des Teilraumes 20 über die Hydraulikleitung 24 wirkt für einen ersten Verstellweg eine hydraulische Kraft auf die Stirnseite des linken Stellkolbenelementes 8b, die eine entsprechende Verschiebung des Stellkolbens 8 bewirkt. Wenn, wie in Fig. 2 dargestellt, das linke Stellkolbenelement 8b aus dem linken Zylindergehäuseteil 4b herausgeführt ist, wirkt die Hydraulikkraft auf die linke Stirnseite des im Durchmesser größer ausgebildeten Zentralkolbens 8a. Während beim ersten Verstellweg aufgrund der kleineren Kolbenfläche eine hohe Verstellgeschwindigkeit bei geringer Reibung erzielt wird, reduziert sich die Verstellgeschwindigkeit reduziert und erreicht ihr Minimum, wenn, wie in Fig. 3 dargestellt, mit dem Zentralkolben 8a die Wirkposition W2 erreicht ist. In dieser Position - bei dem die radiale Anpresskraft des Dichtringes 10 gegenüber der Zylinderinnenwand am größten ist - findet die Synchronisierung für den Gang G3 statt. Nach dem ein Gleichlauf zwischen Schiebemuffeneinheit und Loszahnrad erreicht ist, kann das Durchschalten des Ganges erfolgen, wobei aufgrund des sich wieder erweiternden Durchmessers des zentralen Zylindergehäuseteils 4a die Verstellgeschwindigkeit des Stellkolbens 8 wieder erhöht wird.The center position of the central piston 8a corresponds to the neutral N position, while the left end position of the actuating piston 8 corresponds, for example, to an engaged gear 1 and the right end position of the actuating piston 8 corresponds to an engaged gear G3. As is generally known, the production of a rotationally fixed connection between a rotatably but longitudinally displaceable on the transmission shaft arranged sliding sleeve unit and a sliding sleeve unit associated with the idler gear is required for the gear change. To equalize the different rotational speeds of the gear shaft and the idler gear is arranged between the sliding sleeve unit and the idler gear synchronizing unit, z. B. Borg - Warner required. In the following, the synchronization or the gear change from the position N to the odd gear G3 on the basis of FIGS. 1 to 5 explained in more detail. By applying pressure to the subspace 20 via the hydraulic line 24, a hydraulic force acts on the end face of the left actuating piston element 8b for a first displacement path, which causes a corresponding displacement of the actuating piston 8. If, as in Fig. 2 shown, the left control piston element 8b is led out of the left cylinder housing part 4b, the hydraulic force acts on the left end face of the larger diameter formed in the central piston 8a. While a high adjustment speed is achieved with low friction in the first adjustment due to the smaller piston surface, the adjustment speed is reduced and reaches its minimum, if, as in Fig. 3 represented, with the central piston 8a, the active position W2 is reached. In this position - in which the radial contact pressure of the sealing ring 10 relative to the cylinder inner wall is greatest - takes place the synchronization for the gear G3. After a synchronization between the sliding sleeve unit and the idler gear is reached, the switching of the gear can be done, due to the again expanding diameter of the central Cylinder housing part 4a, the adjustment speed of the actuating piston 8 is increased again.

Selbstverständlich ist die Anwendung des Getriebeaktuators nicht auf die Anwendung als Stellelement für den Gangwechsel in einem automatisierten Schaltgetriebe eingeschränkt; vielmehr bieten sich überall dort Anwendungsmöglichkeiten an, bei denen in Abhängigkeit vom Verstellweg des Stellkolbens unterschiedliche Anforderungen an die Abdichtung der beiden durch den Zentralkolben 8a abgetrennten Druckräume erforderlich ist.Of course, the application of the transmission actuator is not limited to the use as an actuator for the gear change in an automated manual transmission; Rather, there are applications wherever there are different demands on the sealing of the two separated by the central piston 8a pressure chambers is required depending on the adjustment of the actuating piston.
