Abstract

A damped suspension system for conveyors which has a pair of shock absorbers each of which is associated with an initial stressed spring thereby exerting a balancing effect. In preferred embodiments the shock absorbers are provided with means comprising, for example, a casing and a sleeve wherein the cylinder is executing and up and down movement relative to the sleeve. Casing and sleeve each supporting one end of the spring during movement of the conveyer in a straight line. Since, during an inclination of the cabin of the conveyor, both ends of the spring located on the lower side of the cabin are supported only through the casing, there is no possibility of a releasing. Thereby at least the initial force of the spring located on the raised side of the cabin is effective for a reset of the cabin into its vertical position.

Description

Die Erfindung betrifft eine Aufhängung für ein Fördermittel, insbesondere für eine Hängebahn zur Personenbeförderung in Stadtzentren, wobei die Aufhängung eine einerseits an einem in einem Fahrbahnträger geführten Fahrwerk winkelsteif befestigte, und andererseits quer zur Fahrtrichtung gelenkig mit einer Kabine verbundene Tragstange, zwischen der Tragstange und der Kabine entsprechend einem gewünschten maximalen Schwenkwinkel der Kabine angeordnete Anschläge und paarweise an derTragstange und der Kabine angelenkte, im wesentlichen aus einem Zylinder und einem Kolben gebildete Stossdämpfer zum Beeinflussen der Schwenkgeschwindigkeit der Kabine aufweist.The invention relates to a suspension for a means of funding, in particular for a monorail for the transportation of people in city centers, the suspension on the one hand angularly fixed to a running in a carriageway girder, and on the other hand articulated to the direction of travel supporting rod between the supporting rod and the Cab has stops arranged in accordance with a desired maximum pivoting angle of the cabin and shock-absorbers arranged in pairs on the support rod and the cabin and essentially formed from a cylinder and a piston for influencing the pivoting speed of the cabin.

Für derartige Aufhängungen besteht unter anderem die Forderung, von den Fahrgästen als unangenehm empfundene Schräglagen der Kabine in geraden Fahrbahnabschnitten, beispielsweise hervorgerufen durch einseitige Beladung oder Wind, zu vermeiden. Ausserdem sind derartige Schräglagen unerwünscht wegen der dann bestehenden Notwendigkeit, ortsfeste Teile neben der geraden Fahrbahn, z.B. Haltestellen, weiter entfernt vom Umriss der Kabine anzuordnen; dies würde wiederum zu Schwierigkeiten führen, die Kabine an Haltestellen in die zum Andocken erforderliche Vertikallage zu bringen. Für Kurvenfahrten ist die Einhaltung eines bestimmten Schwenkwinkels der Kabine vorgeschrieben, dafür sind an der Kabine und deren Fahrwerk entsprechende Anschläge angeordnet. Aus deren Wirkverbindung beim Auflauf mit einer bestimmten Drehgeschwindigkeit ergibt sich ein soweit wie möglich zu vermeidender seitlicher Ruck auf die Kabine und damit auf die Fahrgäste.For such suspensions, there is a requirement, among other things, to avoid inclined positions of the cabin which the passengers perceive as uncomfortable in straight sections of the road, for example caused by one-sided loading or wind. In addition, such inclinations are undesirable because of the then existing need to have fixed parts next to the straight road, e.g. Stops to be placed further away from the outline of the cabin; this in turn would lead to difficulties in bringing the cabin into the vertical position required for docking. Compliance with a certain swivel angle of the cabin is mandatory for cornering, for this purpose appropriate stops are arranged on the cabin and its undercarriage. From their operative connection during the run-up at a certain rotational speed, there is a lateral jolt to be avoided as far as possible on the cabin and thus on the passengers.

Es ist bekannt, bei einer Aufhängung der gattungsgemässen Art die zuvor aufgezeigten Probleme dadurch anzugehen, dass eine mit der Kabine und der Tragstange zusammenwirkende, blockierbare Vorrichtung (z.B. Hydraulikdämpfer) vorgesehen ist, deren Funktion in Abhängigkeit der von einem in oder an der Kabine befestigten Fliehkraftmesser ermittelten Werte freigegeben wird, wobei die blockierbare Vorrichtung lediglich beim Durchfahren von Kurven der Fliehkraft entsprechende Schwenkbewegungen der Kabine zulässt (DE-A Nr. 2438570). Dadurch ist zunächst eine Stabilisierung der Kabine im geraden Fahrbahnträger bei Stillstand und Fahrt gegenüber einseitiger Beladung oder Seitenwind erreicht. Im weiteren ist nach der vorgenannten Veröffentlichung die dort zugrundeliegende Vorrichtung als Kraftantrieb weitergebildet, wobei dieser Trieb von dem Fliehkraftmesser unter Zwischenschaltung eines Druckreglers gesteuert wird und die Kabine in Kurvenfahrt verschwenkt; dadurch kann der Auflauf der Anschläge an Kabine und Fahrwerk im Rahmen der zulässigen Restseitenbeschleunigung von 1 m/s2 gehalten werden.It is known to tackle the problems outlined above in a suspension of the generic type by providing a lockable device (eg hydraulic damper) which interacts with the cabin and the support rod, the function of which depends on a centrifugal force meter attached in or on the cabin determined values is released, the lockable device only permitting corresponding pivoting movements of the cabin when driving through curves of the centrifugal force (DE-A No. 2438570). As a result, the cabin is initially stabilized in the straight carriageway girder when the vehicle is at a standstill and when traveling against unilateral loading or cross winds. Furthermore, according to the aforementioned publication, the device on which it is based is developed as a power drive, this drive being controlled by the centrifugal force meter with the interposition of a pressure regulator and pivoting the cabin when cornering; As a result, the impact of the stops on the cabin and undercarriage can be kept within the permissible residual lateral acceleration of 1 m / s 2 .

Die nach dem vorbezeichneten Stand der Technik bekannten Lösungsmittel (Fliehkraftmesser, Steuerleitung, Magnetventil, gemäss Fig. 1; Fliehkraftmesser, Druckregler, Hydraulikleitungen, Kraftantrieb, gemäss Fig. 3) werden im Hinblick auf ihre Vielteiligkeit, Kosten und ihre an unterschiedlichen Stellen erforderliche Anbringung als zu aufwendig angesehen.The solvents known according to the abovementioned prior art (centrifugal force meter, control line, solenoid valve, according to FIG. 1; centrifugal force meter, pressure regulator, hydraulic lines, power drive, according to FIG. 3) are considered in view of their versatility, costs and their attachment at different points viewed too expensive.

Demgemäss liegt der Erfindung die Aufgabe zugrunde, eine Aufhängung der gattungsgemässen Art unter Beseitigung der zuvor aufgezeigten Mängel zu verbessern, bei der also insbesondere die Mittel für eine Stabilisierung der Kabine im geraden Fahrbahnträger wie auch für eine Begrenzung der Schräglage der Kabine in Kurvenfahrt kosten-, anordnungs- und funktionsmässig günstiger sein sollen.Accordingly, the invention is based on the object of improving a suspension of the generic type while eliminating the deficiencies indicated above, in which, in particular, the means for stabilizing the cabin in the straight carriageway girder as well as for limiting the inclined position of the cabin when cornering cost arrangement and function should be cheaper.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass jeweils an dem Stossdämpfer eine daran unter Vorspannung abgestützte und mit diesem parallel wirkende Feder angeordnet ist, wobei die Feder derart ausgelegt ist, dass sie bei Erreichen eines bestimmten Schwenkwinkels der Kabine, spätestens im Augenblick des Auflaufens der fahrwerks- und kabinenseitigen Anschläge, eine einer vorgegebenen Restseitenbeschleunigung entsprechende Endkraft aufweist.This object is achieved according to the invention in that in each case a spring is supported on the shock absorber, which is pretensioned thereon and acts in parallel therewith, the spring being designed in such a way that when a certain pivoting angle of the cabin is reached, at the latest when the undercarriage hits - and cabin-side stops, a final force corresponding to a predetermined residual lateral acceleration.

Durch die US-A Nr. 3074358 ist ein Fahrwerk einer Hängebahn bekannt, das in wesentlicher Abweichung von der Gattung des Erfindungsgegenstandes eine in einer elastischen Lagerung am Fahrwerk aufgehängte Tragstange mit einem in Fahrtrichtung gelenkigen Anschluss für eine Kabine aufweist, wobei die gattungsmässig vorausgesetzten Anschläge und hydraulischen Dämpfer nicht vorhanden sind. Die Tragstange ist an ihrem von der elastischen Lagerung abgewandten Ende in Fahrtrichtung durch Längslenker und in Querrichtung durch mit vorgespannten Federn ausgerüstete Gestänge gegenüber dem Fahrwerk stabilisiert, um eine möglichst direkte Längskraftübertragung bzw. einen gewissen Ausgleich von Querkräften aus dem Fahrbetrieb, bei denen es sich gemäss US-A Nr. 3074358 nicht um Zentrifugalkräfte handeln soll, zu erreichen.From US-A No. 3074358 a trolley of a monorail system is known which, in a substantial deviation from the type of the subject matter of the invention, has a support rod suspended in an elastic mounting on the trolley with an articulated connection in the direction of travel for a cabin, the genre presupposed stops and hydraulic dampers are not present. The support rod is stabilized at its end facing away from the elastic mounting in the direction of travel by trailing arms and in the transverse direction by linkage equipped with preloaded springs with respect to the chassis in order to transfer the longitudinal force as directly as possible or to some extent compensate for transverse forces from the driving operation, which are appropriate US-A No. 3074358 is not intended to be about centrifugal forces.

Hinsichtlich der Ausgestaltung der Erfindung und der damit verbundenen Vorteile wird auf die Unteransprüche bzw. auf den speziellen Beschreibungsteil verwiesen.With regard to the configuration of the invention and the associated advantages, reference is made to the subclaims or to the special description part.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere in folgendem:

  • Zunächst ergibt sich, zumindest bei dem Ausführungsbeispiel nach Fig. 1, wegen der hier praktisch nur aus zwei Teilen (Dämpfer, Schraubenfeder) bestehenden Anordnung, eine wesentliche Verringerung der Herstellungskosten. Dabei ist diese Anordnung vorteilhaft allein dort getroffen, wo, nach der Grundkonzeption für die Kabine und das Fahrwerk, die Anlenkpunkte für Stabilisierungs- und Dämpfungselemente vorgegeben sind.
The advantages that can be achieved with the invention are in particular:
  • First of all, at least in the case of the exemplary embodiment according to FIG. 1, there is a substantial reduction in the production costs because of the arrangement which here consists of practically only two parts (damper, coil spring). This arrangement is advantageously made only where, according to the basic concept for the cabin and the chassis, the articulation points for stabilizing and damping elements are specified.

Weiter zeichnet sich der Gegenstand nach der Erfindung wegen seiner einfachen und auch robusten Bauweise durch geringere Störanfälligkeit und grössere Betriebssicherheit aus. Ausserdem ergibt sich mit dieser Aufhängung bei Fahrt in geraden Fahrbahnabschnitten und einseitiger Last eine wesentliche Reduzierung der Pendelschwingungen; diese Schwingungen sind bei dem Ausführungsbeispiel nach Fig. 2 bis 5, oder nach Fig. 6, sogar auf angenähert null reduziert. Bei Schräglage der Kabine, insbesondere bei Kurvenfahrt, erfolgt ein stetiger Kraftaufbau in der auf der angehobenen Seite der Kabine liegenden Feder; da deren Endkraft schliesslich der vorgegebenen Restseitenbeschleunigung entspricht, kommt es unter normalen Betriebsbedingungen nicht zum Auflaufen der fahrwerks- und kabinenseitigen Anschläge, so dass ein seitlicher Ruck auf die Kabine und Fahrgäste vermieden ist.Furthermore, the object according to the invention is characterized by its simple and robust construction due to its lower susceptibility to faults and greater operational security. In addition, this suspension results in a significant reduction in pendulum vibrations when driving in straight road sections and one-sided load; in the embodiment according to FIGS. 2 to 5 or according to FIG. 6, these vibrations are even reduced to approximately zero. When the cabin is in an inclined position, especially when cornering, there is a constant build-up of force in the spring lying on the raised side of the cabin; since their final force finally corresponds to the specified residual lateral acceleration, under normal operating conditions the stops on the chassis and cabin side do not run up, so that a lateral jolt on the cabin and passengers is avoided.

Embodiments of the invention are shown in the drawing and are described in more detail below. Show it:
  • 1 is a monorail with a cabin suspension, in cross section,
  • 2 shows an individual part of another suspension shown in FIGS. 4 and 5 for the monorail according to FIG. 1, this individual part on an enlarged scale compared to FIGS. 4 and 5 and in section along the line 11-11 in FIG. 3 is shown
  • 3 shows the view in the direction of arrow X in FIG. 2,
  • 4 shows the suspension mentioned in FIG. 2, in a position present while driving in a straight section of the road,
  • 5 shows the suspension according to FIG. 4, but when cornering,
  • FIG. 6 shows a further exemplary embodiment, shown on an individual part, which can be used, for example, instead of the individual part according to FIG. 2.

Nach Fig. 1 weist die Hängebahn im wesentlichen einen Fahrbahnträger 6, ein Fahrwerk 7 mit Tragstange 8 und eine daran seitlich-schwenkbar gelagerte Kabine 3 auf. An der Tragstange 8 befinden sich Anschläge 4, die nur bei anormalen Betriebsbedingungen mit kabinenseitigen Anschlägen zusammenwirken. An der Tragstange 8 und der Kabine 3 sind zwei Stossdämpfer 1 angelenkt, an denen jeweils eine unter gleicher Vorspannung stehende und parallel mit dem Stossdämpfer 1 wirkende, als Schraubenfeder ausgebildete Feder 2 angelenkt ist.According to FIG. 1, the monorail has essentially a carriageway support 6, a carriage 7 with a support rod 8 and a cabin 3 which is pivotally mounted thereon. There are stops 4 on the support rod 8, which cooperate with stops on the cabin side only under abnormal operating conditions. On the support rod 8 and the cabin 3, two shock absorbers 1 are articulated, on each of which a spring 2, which is designed as a coil spring and is under the same pretension and acts in parallel with the shock absorber 1, is articulated.

Durch diese Federn 2 werden Pendelschwingungen bei Fahrt in geraden Fahrbahnabschnitten und bei einseitiger Last reduziert, wobei die in sich gleichen Federn 2 ausgleichend im Sinne einer Stabilisierung der Kabine 3wirken. Bei Schräglage der Kabine 3, z.B. während der Kurvenfahrt, steigt die Kraft der auf der angehobenen Seite der Kabine 3 liegenden Feder 2, wogegen sich die Kraft der auf der abgesenkten Seite der Kabine 3 liegenden Feder 2 um den Betrag des Kraftanstieges bei der erstgenannten Feder 2 verringert. Ist beispielsweise die Vorspannkraft der Federn 2 jeweils 1000 kp und der Kraftanstieg in der einen Feder 200 kp, so verringert sich die Kraft in der anderen Feder um 200 kp, so dass für die Rückstellung der Kabine 3 in die Vertikallage der Differenzbetrag, im Beispielsfalle 1200 kp - 800 kp = 400 kp, wirksam wird.These springs 2 reduce pendulum vibrations when driving in straight sections of the road and with one-sided load, the springs 2, which are identical in themselves, having a compensating effect in the sense of stabilizing the cabin 3. With cabin 3 inclined, e.g. during cornering, the force of the spring 2 lying on the raised side of the cabin 3 increases, whereas the force of the spring 2 lying on the lowered side of the cabin 3 decreases by the amount of force increase in the former spring 2. For example, if the preload force of springs 2 is 1000 kp and the force increase in one spring is 200 kp, the force in the other spring is reduced by 200 kp, so that the difference, for example 1200, is used to return cabin 3 to the vertical position kp - 800 kp = 400 kp, takes effect.

Nach den Fig. 2 bis 5 sind der Stossdämpfer 1 und die Feder 2 von einem Gehäuse 5a umgeben, wobei dieses im Bereich des Auges 1 a am Zylinder 1 c des Stossdämpfers 1 befestigt ist und das eine Ende der Feder 2 aufnimmt. Die Feder 2 liegt unter Vorspannung mit ihrem anderen Ende gegen Nasen 5c eines Tellers 5b an, der an dem mit einem Auge 1 d versehenen Kolben 1 b des Stossdämpfers 1 befestigt ist. Die vorgenannten Nasen 5c greifen in Freiräume 5e des Gehäuses 5a ein. Überdies ist die Feder 2 gleichzeitig gegen Nasen 5f des Gehäuses 5a abgestützt; dabei greifen diese Nasen 5f wiederum in Freiräume 5d an dem Teller 5b ein. Die mit den Bezugszeichen 5a bis 5f bezeichneten Teile stellen insgesamt das Mittel 5 dar.According to FIGS. 2 to 5, the shock absorber 1 and the spring 2 are surrounded by a housing 5 a, which is fastened in the area of the eye 1 a to the cylinder 1 c of the shock absorber 1 and which receives one end of the spring 2. The spring 2 rests under tension with its other end against lugs 5c of a plate 5b which is fastened to the piston 1b of the shock absorber 1 provided with an eye 1d. The aforementioned lugs 5c engage in free spaces 5e of the housing 5a. In addition, the spring 2 is simultaneously supported against lugs 5f of the housing 5a; these lugs 5f in turn engage in free spaces 5d on the plate 5b. The parts designated by reference numerals 5a to 5f represent the means 5 as a whole.

Funktionsmässig gilt bei dem Ausführungsbeispiel nach den Fig. 2 bis 5, dass bereits zu Beginn einer beispielsweise durch einseitige Last hervorgerufenen Schwenkbewegung der Kabine 3 die auf deren abgesenkter Seite liegende Feder 2 unwirksam ist, weil sie sich wegen ihrer Anlage an den Nasen 5f des Gehäuses 5a nicht entspannen kann. Damit wird auf der angehobenen Seite der Kabine 3 die Kraft der Feder 2 über ihre Vorspannkraft hinaus entsprechend vergrössert. Dies bedeutet, dass bereits bei kleinen Schwenkbewegungen eine hohe Kraft wirksam ist; falls die Federn 2 wiederum mit jeweils 1000 kp vorgespannt sind, beträgt diese Kraft 1000 kp zuzüglich des Kraftanstieges aufgrund der Anhebung. Dadurch sind Pendelschwingungen der Kabine 3 bei einseitiger Last praktisch ausgeschaltet. Das im Hinblick auf den Fahrkomfort gewollte Schwenken der Kabine 3 bei Kurvenfahrt liegt jedoch vor, weil die dann wirkende Fliehkraft beträchtlich grösser ist als die durch einseitige Last hervorgerufene Kraft.Functionally, in the exemplary embodiment according to FIGS. 2 to 5, the spring 2 lying on its lowered side is ineffective even at the beginning of a pivoting movement of the cabin 3, for example caused by one-sided load, because it contacts the lugs 5f of the housing because of its abutment 5a cannot relax. Thus, the force of the spring 2 is correspondingly increased beyond its pretensioning force on the raised side of the cabin 3. This means that a high force is effective even with small swiveling movements; if the springs 2 are prestressed with 1000 kp each, this force is 1000 kp plus the increase in force due to the increase. As a result, pendulum vibrations of the cabin 3 are practically switched off with one-sided load. However, the desired pivoting of the cabin 3 when cornering is present because the centrifugal force then acting is considerably greater than the force caused by one-sided load.

In dem Ausführungsbeispiel gemäss Fig. 6 ist der Zylinder 1 c des Stossdämpfers 1 in Nähe des Auges 1 a mit einem Flansch 1 e versehen. Am anderen Ende des Zylinders 1 c ist ein Bund 1 f befestigt. Der Kolben 1 b hat ein im Bereich seines Auges 1 d angeschlossenes Gehäuseteil 1 g, das den Zylinder 1 teilweise umgibt. Zwischen diesem Gehäuseteil 1 g und dem Zylinder 1 c befindet sich ein Rohr 1 h, das einen nach aussen gerichteten Kragen 1 j aufweist; Die Feder 2 liegt unter Vorspannung zwischen dem Flansch 1e und dem Kragen 1 j des Rohres 1 h. Bei vertikal hängender Kabine 3 ist das Rohr 1 h gleichzeitig an seinem einen Ende über den Kragen 1 j gegen das Gehäuseteil 1 g und an seinem anderen Ende gegen den Bund 1 f des Zylinders 1 c abgestützt.In the exemplary embodiment according to FIG. 6, the cylinder 1 c of the shock absorber 1 is provided with a flange 1 e in the vicinity of the eye 1 a. At the other end of the cylinder 1 c, a collar 1 f is attached. The piston 1 b has a housing part 1 g connected in the region of its eye 1 d, which partially surrounds the cylinder 1. Between this housing part 1 g and the cylinder 1 c there is a tube 1 h which has an outwardly directed collar 1 j; The spring 2 is under tension between the flange 1e and the collar 1 j of the tube 1 h. With vertically hanging cabin 3, the tube 1 h is supported at one end at the same time over the collar 1 j against the housing part 1 g and at its other end against the collar 1 f of the cylinder 1 c.

Wie zuvor anhand der Fig. 2 bis 5 erläutert, wird auch bei dem Ausführungsbeispiel nach Fig. 6 bei einer geringfügigen Schwenkbewegung der Kabine 3 die auf der abgesenkten Seite liegende Feder 2 unwirksam, weil diese Feder 2 über das Rohr 1 h am Bund 1f des Zylinders 1c abgestützt bleibt, während sich unter Längung des entsprechenden Stossdämpfers 1 das Gehäuseteil 1 g von dem Kragen 1 j entfernt. Die Kraft der Feder 2 auf der angehobenen Seite der Kabine 3 vergrössert sich über ihre Vorspannkraft hinaus, weil bei kürzer werdendem Stossdämpfer 1 das Gehäuseteil 1g den Kragen 1 j und damit die Feder 2 beaufschlagt; die Wirkverbindung zwischen Rohr 1 und Bund 1f f löst sich in diesem Fall.As explained above with reference to FIGS. 2 to 5, the spring 2 lying on the lowered side also becomes ineffective in the exemplary embodiment according to FIG Cylinder 1c remains supported while, while elongating the corresponding shock absorber 1, the housing part 1 g is removed from the collar 1 j. The force of the spring 2 on the raised side of the cabin 3 increases beyond its pretensioning force, because when the shock absorber 1 becomes shorter, the housing part 1g acts on the collar 1 j and thus the spring 2; the operative connection between tube 1 and collar 1f f is released in this case.

Suspension for a means of transport, especially for a suspension railway for passenger transport in town centres, in which the suspension comprises a supporting rod (8), which is secured at one end at a fixed angle to a moving mechanism (7), which is guided in an overhead carrier rail (6), and is connected in an articulated manner at the other end, transversely to the direction of travel, to a cabin (3), stops (4), which are arranged between the supporting rod (8) and the cabin (3) according to a desired maximum angle of pivot of the cabin (3), and shock-absorbers (1), which are articulated in pairs to the supporting rod (8) and the cabin (3) and are essentially formed from a cylinder (1 c) and a piston (1 b), for influencing the pivoting speed of the cabin (3), characterized in that a spring (2) is in each case arranged on the shock-absorber (1), is supported in a pretensioned manner thereon, acts in parallel therewith and is designed such that, when a certain angle of pivot of the cabin (3) is reached, at the latest at the moment at which the stops (4) on the moving mechanism and the cabin side come into contact, it has an end force which corresponds to a predetermined residual lateral acceleration.
2. Suspension according to claim 1, characterized in that the shock-absorber (1) and the spring (2) are provided with means (5 or 1 e to 1j) which, when the cabin (3) is in a sloping position, eliminate the force of the spring (2) on the lowered side of the cabin (3) and increase the force of the spring (2) beyond the pretensioned force on the raised side.
3. Suspension according to claim 2, characterized in that the means (5) consist of a housing (5a), which is secured in the region of an eyelet (1 a) of the shock-absorber (1) and encloses the latter and the spring (2), and a plate (5b), which supports the spring (2) on the other side and is attached to the piston (1 b) of the shock-absorber (1), and ― according to the diameter of the spring (2) -the plate (5b) comprises lugs (5c) arranged at the circumference with intervening free spaces (5d) and the housing (5a) comprises free spaces (5e) corresponding to the lugs (5c) of the plate (5b) and lugs (5f) corresponding to the free spaces (5d) of the plate (5b).
4. Suspension according to claim 2, characterized in that, in order to form the means, the shock-absorber (1), which consists essentially of a cylinder (1 c) and a piston (1 b), comprises a flange (1e) at one end of its cylinder (1c) and a shoulder (1f) at the other end and a housing part (1 g), partially surrounding the cylinder (1 c), at its piston (1 b), a tube (1 h) being arranged between the cylinder (1 c) and the housing part (1 g), which tube (1 h) bears at one end against the collar (1 f) of the cylinder (1 c) and, via a collar (1j) formed at its other end, against the housing part (1 g), and the spring (2) is supported in a pretensioned manner between the flange (1 e) of the cylinder (1c) and the collar (1j) of the tube (1 h).
