摘要:
The invention relates to an axle raising device for a vehicle, in particular for pneumatic-suspension vehicle axes, comprising a support element, a lifting element and a lever element, wherein the support element and the lever element can be coupled to one another by means of the lifting element in such a way that, when the lifting element is actuated, the support element is supported on a frame element of the vehicle and the lever element exerts a preferably vertical force on an axle link of the vehicle in order to raise the latter, wherein the lever element is rotatably or pivotably arranged so as to be substantially positionally fixed in relation to a distal end of the axle link and/or the frame element, and wherein the support element is rotatably or pivotably mounted on the lever element.

A system is provided for use on large vehicles of the type wherein the vehicle frame (12) is supported on vehicle axle assemblies (14, 20, 22) through air bags (26, 30, 32), and each air bag has a lower end coupled to the lower end of an arm such as a swing arm (112) whose upper end is pivotally mounted on the frame. The height of the air bag is sensed by a pair of tilt sensors (50, 52), one on a tilt arm such as the swing arm (112), that has one end pivotally connected to the vehicle frame and an opposite end at least pivotally connected to the vehicle axle assembly. The other sensor senses tilt of the vehicle frame about an axis parallel to the axes of pivoting of the tilt arm. Each tilt sensor senses tilt of its location with respect to gravity, and the difference in tilt indicates air bag height.

Die Erfindung betrifft ein variables Federungssystem 10 für ein Kraftfahrzeug mit mindestens einem Hauptfederelement 12 und mindestens einem Dämpferelement 14, wobei das Hauptfederelement 12 mindestens eine Tragfeder, in Einfederrichtung eine Druckzusatzfeder und in Ausfederrichtung gegebenenfalls eine Zuganschlagfeder umfasst, und das Hauptfederelement 12 und das Dämpferelement 14 jeweils zwischen Radaufhängung 16 und Fahrzeugaufbau angeordnet sind. Die Erfindung zeichnet sich dadurch aus, dass dem Hauptfederelement 12 zwischen Radaufhängung 16 und Fahrzeugaufbau ein entgegenwirkendes zweites Federelement 18 zugeordnet ist und dieses zweite Federelement 18 über ein Verstellsystem 20 wahlweise in Wirkung bringbar ist.

An axle connection device (100) designed to be welded to an axle housing (102) to permit a vehicle suspension system (106) to be connected to the axle housing (102) is disclosed. The device (100) includes a generally flat baseplate (132) having curvilinear ends (134) separated by a relatively long and narrow waist (136). Each end includes a curvilinear side rim (138) and two rounded corners (140, 142) from which longitudinally extending edges positioned on opposite sides of the device (100) smoothly taper towards the waist (136). The device (100) also includes a generally horizontally projecting plane (144) having a waist (146) aligned with the waist (136) of the baseplate (132) to divide the plane (144) into two distinct portions. The plane (144) also has two supporting sidewalls (148). Both sidewalls (148) extend from just inside the rounded corners (140, 142) of a respective end of the baseplate (132) and taper towards associated corners of the horizontally projecting plane (144). Each portion of the plane (144) includes a generally rounded boss (150) extending from the plane (144). A slot (152) extending from the intersection of the baseplate (132) and the plane (144) is incorporated in each boss (150) to allow a connection bolt (128) to pass through the device (100). The construction of the device (100) permits it to accommodate varying pinion angles and axle housing (102) mismatch. The preferred method of welding the axle connection device (100) to the axle housing (102) is also disclosed.
摘要:
A suspension assembly for mounting a wheel assembly to any wheel position of a vehicle, the suspension assembly being pneumatically controlled to adjust both the ground clearance of the vehicle and its wheel-track width, the suspension assembly also being mountable at any wheel position whether the wheel at that position is to be steerable or nonsteerable. The suspension system includes upper and lower control arms connected between a frame attachable to the vehicle and a kingpin assembly to provide a parallelogram linkage. It also includes at least one pneumatically actuated linear actuator to control the angular disposition of the lower control arm with respect to the frame and thereby control the ground clearance and wheel-track width of the vehicle. The parallelogram geometry provides the upper and lower control arms with at least 120 degrees of angular travel. When in a stowed position, the control arms are nearly vertical and fit, with the kingpin, within a space effectively equal to that occupied by the linear actuators and the frame. The disposition of the suspension assembly components is such that wheels are drivable with wheel-mounted electric drives, inboard-mounted electric drives, or a conventional engine drive.

Anstatt bei einer Anfahrhilfe zur Traktionserhöhung bei geringem Reibwert an einem Fahrzeug mit einer entlastbaren Achse die Steuerung der Achslastverlagerung auf der Basis von Drücken in Luftfederbälgen der Antriebsachse und der entlastbaren Achse des Fahrzeugs vorzunehmen, wird entsprechend der Erfindung diese Achslastverlagerung auf der Basis von aktuellen Achslast-Gewichtskräften an diesen Achsen durchgeführt. Dadurch wird die Abhängigkeit der Anfahrhilfen-Traktionserhöhung von der Niveauhöhe des Fahrzeugs beseitigt und es wird eine sich üblicherweise mit der Niveauhöhe ändernde Hub-/Tragkraft-Charakteristik von Luftfederbälgen bei der Achslastverlagerung berücksichtigt.
