Stoßdämpfer für Fahrzeuge mit Federn und Reibelementen. Patentiert im Deutschen Reiche vom 20. Juni 1913 ab. Shock absorbers for vehicles with springs and friction elements. Patented in the German Empire on June 20, 1913.

Die Erfindung betrifft einen Stoßdämpfer für Fahrzeuge, bei dem die Stöße durch Feder- und Reibungs wirkung unschädlich gemacht werden. Es sind solche Stoßdämpfer für Fahrzeuge bekannt, bei denen entweder Reibelemente oder aber Federn angeordnet sind. Die Stoßdämpfer, bei denen nur Reibflächen in Wirkung treten, haben den großen Nachteil, daß sich diese Reibflächen infolge ihres ständigen Arbeitens leicht abnutzen. Ihr Vorteil besteht darin, daß sie imstande sind, mit kleinen Flächen große Kräfte auszugleichen. Die Stoßdämpfer mit Federn sind bedeutend widerstandsfähiger, müssen aber, um große Kräfte überwinden zu können, entsprechend groß ausgeführt werden.The invention relates to a shock absorber for vehicles, in which the shocks by spring and frictional effects can be rendered harmless. These are shock absorbers for vehicles known, in which either friction elements or springs are arranged. The shock absorbers, in which only friction surfaces come into effect, have the major disadvantage that these friction surfaces wear out easily as a result of their constant work. Your advantage is there in that they are able to balance large forces with small areas. The shock absorbers with springs are significantly more resistant, but must be made correspondingly large in order to be able to overcome large forces will.

In der Erfindung sind durch Vereinigung dieser beiden Wirkungen die Vorteile jeder derselben ausgenutzt unter Vermeidung der ihnen anhaftenden Nachteile. Die Erfindung besteht im wesentlichen darin, daß U-förmige, innerhalb der Reibelemente liegende und durch diese in ihrer U-Form gespannt gehaltene Blattfedern sich mit ihren Enden gegen die gegenüber den Reibelementen verdrehbaren Schwingungshebel legen und so die schwächeren Stöße allein aufnehmen, während bei starken Stößen die ausschwingenden Schwingungshebel gegen Anschläge der Reibelemente stoßen und diese ebenfalls zur Wirkung bringen.In the invention, by combining these two effects, there are advantages of each of them exploited while avoiding their inherent disadvantages. The invention exists essentially in the fact that U-shaped, lying within the friction elements and through them in their U-shape held tensioned leaf springs with their ends against the opposite Place rotatable vibration levers on the friction elements and thus absorb the weaker impacts by themselves, while in the case of strong impacts, the swinging vibration levers hit against stops of the friction elements and these also bring to effect.

Dabei sind die Federspannungen so getroffen, daß, wenn der eine Federteil durch den Hebel in einer Richtung genügend zusammengedrückt ist, der andere Federteil dadurch nicht vollständig entspannt wird.The spring tensions are made so that when the one spring part through the lever is compressed enough in one direction, the other spring part is not completely is relaxed.

Eine Ausführungsform des Erfindungsgegenstandes ist auf der Zeichnung dargestellt, und zwar zeigt:An embodiment of the subject matter of the invention is shown in the drawing, and although shows:

Fig. 2 einen Schnitt nach der Linie 2-2 der Fig. i.FIG. 2 shows a section along the line 2-2 of FIG.

Das eine Ende eines Armes 10 ist durch eine Stange 11 mit der Achse oder mit einem anderen Teil des Laufgestelles des Fahrzeugs verbunden; das andere Ende des Armes 10 ist mit einem Auge 16 zur Aufnahme eines Bolzens 15 versehen. Dieser preßt zwei Druckscheiben 17 gegen entsprechend gestaltete Ringe 18, die an zwei durch Bolzen Ι2^Λ am Wagengestell 14 befestigten Armen 12 und 13 angebracht sind.One end of an arm 10 is connected by a rod 11 to the axle or to another part of the bogie of the vehicle; the other end of the arm 10 is provided with an eye 16 for receiving a bolt 15. This presses two pressure disks 17 against correspondingly shaped rings 18, the fixed two by bolts ^Ι2 Λ on the carriage frame 14 are mounted arms 12 and 13. FIG.

Zwischen den Ringen 18 befindet sich eine zweiteilige Scheibe, deren Teile 19 und 20 zwischen ringförmigen Flanschen ΐδ¹¹ der Ringe 18 gehalten werden; in der Mitte weisen diese Teile Vertiefungen 19^ zur Aufnahme des Auges 16 des Armes 10 auf.Between the rings 18 there is a two-part disc, the parts 19 and 20 of which are held between annular flanges ΐδ ^{11 of} the rings 18; in the middle, these parts have depressions 19 ^ for receiving the eye 16 of the arm 10.

Die Teile 19 und 20 haben schräg nach außen verlaufende Ansätze 21, zwischen diesen An-Sätzen und den Ringen 18 sind Ringe 22 aus Leder oder anderem Reibungsmaterial eingelegt. In den Scheibenteilen 19 und 20 sind weitere Vertiefungen 19* und 20* zur Aufnahme einer Blattfeder 23 vorgesehen, die im wesentlichen U-förmig gebogen ist und derenThe parts 19 and 20 have outwardly sloping lugs 21, between these lugs and rings 22 made of leather or other friction material are inserted into the rings 18. In the disc parts 19 and 20 there are further recesses 19 * and 20 * for receiving a leaf spring 23 is provided which is bent in a substantially U-shape and whose

Claims

Arch lies in the relevant depressions in the disc parts. The wells are on the inside of the disc parts bounded by a sector-shaped part 24 in which the Eye 16 of the lever 10 is mounted. The outer walls 25 of these recesses are U-shaped Shape and are for receiving screws 27 for screwing the disc parts together 19 and 20 provided with reinforcements 26 and 26 ".

The recesses 19 ⁶ , 20 * are open on one side for the passage of the ends of the spring 23, so that the spring lies against the lever 10 with pressure from both sides. From Fig. 1 it can be seen that the ends 24 ″ of the sector-shaped piece 24 are somewhat further apart than the lever 10 is wide at this point, so that the lever can perform a slight movement in both directions under the action of a spring without touching the sector 24 In the same way, the recess 28 in front of the wall 29 of the depressions 19 *, 20 * is provided for the outer leaf of the spring 23.

Now the lever 10 due to the impact shifted against the arms 12, 13, the shift is initially through the Spring action alone opposes a resistance. If it is stronger than the resistance Shock comes the spring with that stop 29 in contact to which the lever 10 is moved, and it now comes Friction between the rings 18 on the one hand and the discs 19, 20 on the other hand with the interposed leather ring 22 to the effect.

The spring ends expediently lie against the with such a tension Lever 10 that the spring is not completely relaxed on one side when the Has moved the lever the furthest to the other side. The nib is made so strong that, without coming into direct contact with the rubbing parts, they are their largest Can take up resistance.

In order to prevent the spring from being able to move on the curved part, an adjusting screw 30 is arranged, which ^{sits in the reinforced part 26 a of} the disk parts 19 and 20.

From Fig. Ι it can be seen that when the lever 10 is brought from its central position, the points of support between the spring and the Lever to be moved; this increases the stiffness of the spring on the side, according to which the lever moves, and accordingly the elasticity of the spring on the other side enlarged. The connection of the support points between the spring and the Lever depends on the size and shape of the spring and on the angle with which the spring rests against the lever.

The arm 12 is provided with stops 12 ⁶ , between which the projecting part I3 ^{a of} the lever 13 rests.

Pa τ ε .ν τ - A ν s ρ r υ c η:

Shock absorbers for vehicles with springs and friction elements, characterized by U-shaped, lying within the friction elements and tensioned by them in their U-shape held leaf springs (23), the ends of which lie against the oscillating lever, which can be rotated with respect to the friction elements, and thus the weaker impacts record alone, while the swinging vibration lever against stops of the friction elements in the event of strong impacts and also brings this to effect.
