Abstract

The wheel hub binding has two parallel transverse control arms (5) provided for a lateral wheel guiding mechanism and a moment support, where an external wheel guiding mechanism is provided for supporting a toe angle of a vehicle wheel (1). The wheel guidance mechanisms are supported by a torsion-rigid, vertical linear guiding mechanism about a normal axis. An external support-wheel bearing is implemented at the wheel hub binding.

Description

Die Erfindung bezieht sich auf Rollenprüfstände zur Erprobung von Fahrzeugen und Vorrichtungen mit denen Fahrzeuge auf solchen Prüfständen festgehalten werden, im weiteren Fahrzeugfesselung genannt. Solche Fesselungen haben sowohl seitliche Zufallskräfte, vor allem aber die Abstützkräfte in Fahrzeuglängsrichtung, die aus der Zugkraft, bzw. Bremskraft des Fahrzeugs herrühren, aufzunehmen. Damit besteht zusätzlich die Möglichkeit, in die Längsabstützung der Fesselung eine Zugkraftmesseinrichtung zu integieren. Eine solche Zugkraftmessung ist beispielsweise in den Patenten JP 62209334 A und JP 06249754 A integriert in eine Pufferabstützung und eine Seilabspannung beschrieben. Problematisch bei allen Fixierungen an der Karosserie ist die elastische Verschiebung der angetriebenen Räder in Längsrichtung bei Zugkräften infolge der elastischen Achslagerung. Damit wandert das Rad aus der Mitte des Laufrollenscheitels, was zu einer zusätzlichen Längskraft und damit zu einem Messfehler führt.The invention relates to chassis dynamometers for testing vehicles and devices with which vehicles are held on such test benches, called in the rest Fahrzeugfesselung. Such restraints have both lateral random forces, but especially the supporting forces in the vehicle longitudinal direction, resulting from the tensile force, or braking force of the vehicle to record. Thus, it is additionally possible to integrate in the longitudinal support of the bondage a Zugkraftmesseinrichtung. Such a tensile force measurement is for example in the patents JP 62209334 A and JP 06249754 A integrated into a buffer support and a Seilabspannung described. The problem with all fixings on the body is the elastic displacement of the driven wheels in the longitudinal direction at tensile forces due to the elastic axle bearing. Thus, the wheel moves from the middle of the roller crown, resulting in an additional longitudinal force and thus a measurement error.

Ebenso Stand der Technik sind sogenannte Radnabenfesselungen, bei denen über zusätzliche Radlager an Radaußenseite die Radmitten festgehalten werden und sich nicht verschieben können. In der Publikation „Neuer Außengeräuschprüfstand im Entwicklungsprozess bei BMW" der Automobiltechnischen Zeitschrift ATZ 4/2006, Seite 256, ist eine Radnabenfesselung mittels zweier Lenker in Dreiecksanordnung abgebildet, die Längs- und Seitenkräfte gemeinsam aufnehmen.As well The state of the art are so-called hubbands, which have additional wheel bearings at the wheel outside the wheel centers are held and can not move. In the Publication "Neuer External noise test bench in the development process at BMW "the automobile technical Journal ATZ 4/2006, page 256, is a hub collar using two handlebars shown in triangular arrangement, the longitudinal and lateral forces record together.

Durch exakte Anordnung der beiden Lenker in Längs- und Querrichtung können diese Kraftkomponenten getrennt abgestützt und mit einer Kraftmessdose im Längslenker die Zugkraft gemessen werden. Da die Abstützung an der Nabe von außen, also außerhalb der Radmitte erfolgt, ergibt sich aus dem Hebelsarm zwischen Zugkraft in Radmitte und Abstützkraft des Längslenkers ein Drehmoment um die Lenkachse des Rades, siehe 1. In Summe heben sich die Momente auf das rechte und linke Rad auf, belasten aber die Lenkung und führen über die elastische Fahrwerkslagerung zu lastabhängigen Veränderungen der Vorspur und des Rollwiderstandes.By exact arrangement of the two links in the longitudinal and transverse directions, these force components can be supported separately and with a load cell in the trailing arm, the tensile force can be measured. Since the support on the hub from the outside, that is outside of the wheel center, resulting from the lever arm between tensile force in the wheel center and supporting force of the trailing arm, a torque about the steering axis of the wheel, see 1 , In sum, the moments cancel each other out on the right and left wheels, but burden the steering and lead via the elastic suspension bearing to load-dependent changes in toe-in and rolling resistance.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Messfehler zufolge dieser Momenteneinleitung in das Fahrwerk bei einer Radnabenfesselung zu vermeiden.Of the present invention is based on the object, the measurement error according to this torque introduction into the suspension in a hubbelt to avoid.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die äußere Abstütz-Radlagerung an der Nabe momentensteif ausgeführt wird und die seitliche Abstützung als Lenkerparallelogramm ausgeführt wird. Das äußere Drehmoment wird somit direkt vom Rad in die Nabenfesselung und nicht in das Fahrwerk eingeleitet.These Task is inventively characterized solved, that the outer support wheel bearing at the Hub executed torque-resistant is and the lateral support designed as handlebar parallelogram becomes. The external torque is thus directly from the wheel in the hub shackles and not in the chassis initiated.

Da die Lenker der Fesselung in Stahl-Gelenkköpfen gelagert sind, ist diese Radführung wesentlich steifer als die gummigelagerten Lenker des Fahrwerks und das Rad kann keine Spuränderungen erfahren.There the handlebars of the bondage are stored in steel rod ends, this is Suspension, much stiffer than the rubber-mounted handlebars of the chassis and the wheel can not change lanes.

Eine weitere Ausgestaltung der Erfindung ist im Patentanspruch 3 aufgeführt. Das Moment zwischen Zugkraft und Abstützkraft kann anstelle eines Lenkerparallelogramms auch durch eine torsionssteife vertikale Linearführung aufgenommen werden, die direkt an der Radaußenseite ansetzt und nur Bewegungen in vertikaler Richtung infolge der Reifeneinfederung zulässt. Die exakte Messung der Längskraftkomponente muss in der Linearführung oder ihrer äußeren Lagerung realisiert werden.A Another embodiment of the invention is set forth in claim 3. The Moment between traction and support force can instead of a Lenkerparallelogramms also be absorbed by a torsionally stiff vertical linear guide, the direct at the wheel outside attaches and only movements in the vertical direction due to the Reifeneinfederung allows. The exact measurement of the longitudinal force component must be in the linear guide or their external storage will be realized.

Ein Ausführungsbeispiel der Erfindung wird unter Bezugnahme auf 1 erläutert. 1 zeigt eine Draufsicht auf ein rechtes Vorderrad mit Radnabenfesselung.An embodiment of the invention will be made with reference to 1 explained. 1 shows a plan view of a right front wheel with Hubbeltung.

Mit der Felge des Rades 1 fest verschraubt ist der Felgenadapter 2, der sich mitdreht. Er ist mit dem Kugellager 3 in dem feststehenden Außenring 4 gelagert, an dem die beiden Parallelogrammlenker 5 der Seitenkraftabstützung und der Längslenker 6 angreifen. Die reibungsarmen Gelenkköpfe 7 der Parallelogrammlenker sorgen dafür, dass die gesamte Längskraft verlustfrei vom Längslenker 6 auf die Kraftmessdose 8 übertragen wird. Die Lagerböcke 9 und 10 sind auf einer gemeinsamen Platte montiert, die zur Anpassung an die Fahrzeugbreite querverschieblich ist.With the rim of the wheel 1 firmly screwed is the rim adapter 2 who turns around. He is with the ball bearing 3 in the fixed outer ring 4 stored on which the two parallelogram 5 the lateral force support and the trailing arm 6 attack. The low-friction rod ends 7 The parallelogram link ensures that the entire longitudinal force is lossless from the trailing arm 6 on the load cell 8th is transmitted. The bearing blocks 9 and 10 are mounted on a common plate, which is transversely displaceable to adapt to the vehicle width.
