Es zeigtThe invention and further advantageous details of the Invention, which are the subject of dependent claims in the following with reference to one shown in the drawing Embodiment explained in more detail. It shows
Fig. 1 eine perspektivische Prinzipdarstellung einer Radaufhängung für die Hinterräder eines Personenkraftwagens, die begrenzt lenkbar sein sollen und Fig. 1 is a perspective schematic representation of a wheel suspension for the rear wheels of a passenger car, which should be steerable to a limited extent and
Fig. 2 den Verstellmechanismus, mit dem die Lenkbewegung erzeugt wird. Fig. 2 shows the adjustment mechanism with which the steering movement is generated.
Die in Fig. 1 erkennbare Radaufhängung umfaßt einen das Rad 1 lagernden Radträger 2, der fest mit einem etwa in Fahrtrichtung F nach vorne gerichteten Längsarm 3 verbunden ist. In Querrichtung ist der Radträger 2 über einen oberen Querlenker 4 und einen unteren Querlenker 5 mit dem nicht näher dargestellten Fahrzeugaufbau oder einem dort abgestützten Hilfsarm o.dgl. verbunden. Über eine in Fig. 2 näher beschriebene Verstellvorrichtung kann das vordere, aufbauseitige Ende des Längsarms 3 in Fahrzeugquerrichtung im Sinne des Doppelpfeiles 6 verstellt werden. Das Rad dreht sich dabei etwa um eine Hochachse, die durch die radträgerseitigen Gelenke des oberen Querlenkers 4 und des unteren Querlenkers 5 definiert ist. Die Lenkbewegung ist in Fig. 1 durch die Lenkwinkel α angedeutet.The wheel suspension recognizable in FIG. 1 comprises a wheel carrier 2 which supports the wheel 1 and which is firmly connected to a longitudinal arm 3 which is directed forwards in the direction of travel F. In the transverse direction, the wheel carrier 2 is or the like via an upper wishbone 4 and a lower wishbone 5 with the vehicle body (not shown) or an auxiliary arm supported there. connected. The front, body-side end of the longitudinal arm 3 can be adjusted in the transverse direction of the vehicle in the sense of the double arrow 6 by means of an adjusting device described in more detail in FIG. 2. The wheel rotates about a vertical axis, which is defined by the wheel carrier-side joints of the upper control arm 4 and the lower control arm 5 . The steering movement is indicated in Fig. 1 by the steering angle α .
In Fig. 2 ist der Längsarm 3 mit seinem vorderen Lager auge 7 angedeutet, in das die Außenschale 8 eines Gummilagers 9 fest eingesetzt ist. Die Innenbuchse 10 des Gummilagers 9 ist fest auf einer Lagerachse 11 angeordnet.In Fig. 2, the longitudinal arm 3 with its front bearing eye 7 is indicated, in which the outer shell 8 of a rubber bearing 9 is firmly inserted. The inner bush 10 of the rubber bearing 9 is fixedly arranged on a bearing axis 11 .
Zum Verstellen des vorderen Endes des Lagerarmes 3 in Fahrzeugquerrichtung im Sinne des Doppelpfeiles 6 ist eine durch einen Elektromotor 12 antreibbare Verstell spindel 13 vorgesehen, die über eine drehfest abge stützte Mutter 14, die als Kugelumlaufmutter ausgebildet sein kann, den Längsarm 3 verlagert. Die Mutter 14 verlagert hierzu das gesamte aufbauseitige Gummilager 9 des Längsarms 3. Hierzu ist die Mutter 14 an der am Fahrzeugaufbau 15 quer verschiebbar gelagerten Lager achse 11 befestigt, die zwischen ihren Lagerstellen 16 mit dem den Längsarm 3 an dessen vorderem Ende lagernden Gummilager 9 fest verbunden ist. Die Lagerstellen 16 umfassen Gleitlagerbuchsen 17, von denen die gemäß Fig. 2 linke Buchse direkt in einem aufbaufesten Stützauge aufgenommen ist, während die rechte Buchse in dem Lagerhals 18 einer Befestigungsglocke 19 für den Elektro motor 12 aufgenommen ist.To adjust the front end of the bearing arm 3 in the vehicle transverse direction in the sense of the double arrow 6 , a drivable by an electric motor 12 adjustment spindle 13 is provided, the longitudinal arm 3 relocated via a non-rotatably supported nut 14 , which can be designed as a recirculating ball nut. For this purpose, the nut 14 shifts the entire body-side rubber bearing 9 of the longitudinal arm 3 . For this purpose, the nut 14 is attached to the axially displaceably mounted bearing 11 on the vehicle body 15 , which is fixedly connected between its bearing points 16 with the rubber arm 9 supporting the longitudinal arm 3 at its front end. The bearings 16 comprise plain bearing bushes 17 , of which the left bushing according to FIG. 2 is received directly in a support eye fixed to the structure, while the right bushing is received in the bearing neck 18 of a fastening bell 19 for the electric motor 12 .
Aus Fig. 2 geht ferner hervor, daß die Lagerachse 11 hohl ist und die Verstellspindel 13 teilweise umgibt. Die Mutter 14 ist an dem gemäß Fig. 2 rechten Ende in eine entsprechende Erweiterungsbohrung 20 in den Hohlraum der Lagerachse 11 eingesetzt, in deren anderem Ende ein Wegsensor 21 eingesetzt ist. Der Wegsensor 21 umfaßt einen Meßstift 22, der federnd gegen das stirnseitige Ende der Verstellspindel 13 drückt. Der Wegsensor 21 kann als Linearpotentiometer, als induktiver oder als kapazitiver Weggeber ausgebildet sein.From Fig. 2 also shows that the bearing shaft 11 is hollow and the adjusting spindle 13 partially surrounds. The nut 14 is inserted at the right end according to FIG. 2 into a corresponding extension bore 20 in the cavity of the bearing axis 11 , in the other end of which a displacement sensor 21 is inserted. The displacement sensor 21 comprises a measuring pin 22 which presses resiliently against the front end of the adjusting spindle 13 . The displacement sensor 21 can be designed as a linear potentiometer, as an inductive or as a capacitive displacement sensor.
Wie man erkennt, ist die beschriebene Verstellvorrich tung verhältnismäßig einfach mechanisch aufgebaut und ermöglicht einen kompakten, geschützten Einbau der Verstellelemente und des Wegsensors 21. Die Stromführungs kabel 23 ermöglichen eine zuverlässige Informationsüber mittlung zu einer entsprechenden Schaltlogik, die wiederum den Elektromotor 12 steuert.As can be seen, the described Verstellvorrich device is relatively simple mechanical and enables a compact, protected installation of the adjusting elements and the displacement sensor 21st The current carrying cable 23 enable reliable information transmission to a corresponding switching logic, which in turn controls the electric motor 12 .
Abweichend von der beschriebenen Ausführungsform könnte das Innengewinde der Mutter auch in den Hohlraum der Lagerachse 11 eingearbeitet sein, so daß diese Lager achse zumindest mit einem gewissen Abschnitt ihrer Längserstreckung gewissermaßen auch die Mutter bildet. Ferner ist es möglich, das Innenteil bzw. die Innen buchse 10 des Gummilagers 9 des Längsarms 3 auf einem feststehenden Lagerbolzen zu befestigen und den Spindel trieb am Längsarm 3 angreifen zu lassen. Die Lenkbe wegung würde dann durch Verformung des Gummilagers ermöglicht und die beschriebenen Gleitlager könnten entfallen.Deviating from the described embodiment, the internal thread of the nut could also be incorporated into the cavity of the bearing axis 11 , so that this bearing axis also forms the nut, at least with a certain portion of its longitudinal extent. It is also possible to fasten the inner part or the inner bush 10 of the rubber bearing 9 of the longitudinal arm 3 on a fixed bearing pin and to drive the spindle to engage the longitudinal arm 3 . The Lenkbe movement would then be made possible by deformation of the rubber bearing and the slide bearings described could be omitted.
Die Lenkbewegung des anderen Rades der Hinterachse kann durch einen zweiten elektromechanischen Stellantrieb der beschriebenen Art bewerkstelligt werden. Es ist aber auch möglich, die beiden Achshälften über eine mechanische Verbindung, wie etwa eine Spurstange o.dgl. miteinander zu koppeln.The steering movement of the other wheel on the rear axle can by a second electromechanical actuator described type can be accomplished. But it is also possible the two axle halves over one mechanical connection, such as a tie rod or the like. to couple with each other.
