Abstract:
The invention relates to a twist-beam rear axle (1) for a motor vehicle having two longitudinal control arms (2; 3), which are spaced apart from each other in the transverse direction of the vehicle; a cross strut (8), which extends in the transverse direction of the vehicle between the longitudinal control arms and is rigidly connected to the latter in the region of their two ends, and has a profile that can be twisted but is flexurally rigid and has a cross strut opening (9), which extends in the longitudinal direction of said cross strut; and a stabiliser (10), which extends along the cross strut (8) and is arranged at least partially in the interior of the profile of the cross strut (8), and engages in a form-fitting and detachable manner in a respective recess (13) in the region of its two stabiliser ends (11) for connection to the longitudinal control arms (2; 3), said recess having an opening (14), via which the stabiliser end (11) can be introduced and removed, the opening (14) of at least one of the two recesses (13) extending approximately transversely to the longitudinal direction of the longitudinal control arm and approximately transversely to the longitudinal direction of the cross strut opening (8), such that the stabiliser (10) can be installed and removed via the cross strut opening (9).
Abstract:
A vehicle suspension system having a pair of hanger brackets (5) and a pair of beams (15). A first end of each beam is attached, via a bushing sleeve to each hanger bracket, and an axle (19) is rigidly attached to the second end of each beam. Each beam is manufactured from a plurality of layers of laminate material which extend circumferentially around the axle and the bushing sleeve (30). An adhesive layer extends between the bushing sleeve and axle, and the layers of laminated material, for securing the bushing sleeve and axle to the beam. Inasmuch as the laminate material and adhesive have relatively low modulus of elasticity, these materials flex in response to movement of the axle, thereby assuring that the connection between the laminate beam (15) and the axle (19) remains stable, even as the axle moves in response to forces acting thereon. In another embodiment of the invention, each beam (47) is integrally formed with an air spring piston (48). In another embodiment of the invention, a parallelogram suspension is provided with a pair of parallel and spaced-apart control arms (62) manufactured of laminate material. Alternatively, the control arms of the parallelogram-type suspension may be integrally formed with a stabilizer bar (68) extending therebetween. In alternative embodiments, a pair of air spring pistons (48) may be mounted on the stabilizer bar (68), substantially reducing the weight and cost associated with the manufacture and operation of air spring suspension systems.
Abstract:
A joint (12) between an at least hollow ended, generally cylindrical first component (14) and a second component (16). The first component has a first end portion (18) terminating in a first free end region (20), a second end portion (22) terminating in a second free end region, and a mid portion (24) extending between the first and second end portions. The mid portion (24) has a first predetermined external diameter and the first end portion (18) has an external diameter which increases gradually from the first predetermined external diameter to a second predetermined external diameter at the first free end region (20). The first end portion is adapted to be pushed onto a tapered pin (26) extending from the second component (16) to a joined position. To ensure transmission of rotational forces, in the joined position the first free end region (20) of the first component extends into a generally ring-shaped socket (28) in the second component, with the socket having at least one substantially planar circumferentially and axially extending surface (30) against which a corresponding planar surface (32) extending axially from the free end (34) of the first free end region (20) abuts.
Abstract:
The invention concerns an axle suspension system for rigid axles (1) on vehicles, in particular utility vehicles. According to the invention, there is provided on each side of the vehicle at approximately the same height at least one longitudinal connecting rod (2, 3) which extends in the longitudinal direction of the vehicle and connects the vehicle axle to the vehicle body in a vertically movable manner. There is further provided, at a different height from the longitudinal connecting rod (2, 3), a triangular connecting rod (4) which is articulated on the vehicle axle (1) and the vehicle body such that it is offset centrally and laterally. The system is further provided with a stabilizer rod (6) comprising a torsion spring rod which counteracts lateral tilting movements by torsion stresses. In this arrangement, the stabilizer rod (6) is disposed directly between the longitudinal connecting rods (2, 3) and its ends are connected thereto in the manner of universal joints but such that the stabilizer rod is rotationally rigid.
Abstract:
Die Erfindung betrifft eine Kraftfahrzeug-Hinterachse (1) des Verbundlenkerachsetyps mit radtragenden Längslenkern (2) in Blechschalenbauweise, die durch eine tordierbare biegesteife Querstrebe (4) miteinander verbunden sind, sowie mit einem mit seinen Enden an den Längslenkern angreifenden, quer zur Fahrzeuglängsachse verlaufenden stabförmigen Stabilisator (5). Erfindungsgemäß erfolgt die Anbindung der Stabilisatorenden des als geradliniger Drehstab ausgebildeten Stabilisators an die Längslenker jeweils über ein im aufbauseitigen Endbereich des Schalenkörpers des betreffenden Längslenkers einliegendes biegesteifes Koppelglied (8), dessen radseitiges Ende eine Ausnehmung zur Verbindung mit dem dort einsteckenden Stabilisatorende und dessen aufbauseitiges Ende eine Ausnehmung (82) zum Einpressen des Lenkerlagers aufweist, wobei das Koppelglied zumindest in seinem die aufbauseitige Ausnehmung enthaltenden Endbereich zumindest kraftschlüssig mit dem ihn umgebenden Schalenkörper (7) verbunden ist. Bei der erfindungsgemäßen Bauweise ist die Anbindung von Stabilisatoren mit beliebigem Durchmesser an dünnwandige Längslenker völlig unproblematisch.
Abstract:
The invention relates to a suspension system for motor vehicles of the type including a transverse bar (8) connected at its ends to the central parts of two longitudinal arms (2), each of which is articulated at one end to the body of the motor vehicle about a transverse axis (4), and at its opposite end has a bearing (6) for a wheel. In this invention, the said transverse bar is constituted by a tublar component which has a substantially circular, open cross-section and is fixed at each end in a cooperating seat in the respective longitudinal arm (2) by means of a series of radial bolts (14) which engage that part of the transverse bar (8) diametrally opposite the aperture in the bar itself. Within each end of the transverse bar (8) there is a tile-shaped locking element (17) provided with a series of nuts (18) which are engaged by the ends of the said radial fixing bolts (14). This tile-shaped element which may, for example, extend through an angle of about 180°, has a cross-section the thickness whereof decreases progressively from its centre towards its ends. Thus the ends of the bar (8) are locked in the respective longitudinal arms without causing discontinuous stresses in the bar itself.
