Definitions

  • the transverse leaf spring is linked by additional coupling rods.
  • these coupling rods introduced additional components that are subject to wear, weight, hysteresis and deformation.
  • the coupling rods require a greater overall height.
  • DE 102011 116 034 A1 describes, for example, a wheel suspension device for a motor vehicle, with a wheel guide device and with a leaf spring device which is articulated at a first coupling point to a coupling device which is articulated to the wheel guide device at a second coupling point is.
  • a vehicle in particular a commercial vehicle, has a vehicle axle according to the invention.
  • axles As an alternative to coupling arm axles, other basic axle types are also conceivable, which essentially have the same advantages as semi-rigid axles, in particular fewer bearing points compared to conventional independent wheel suspensions, fewer components, good wheel control properties, less installation space required in the vertical direction and significantly improved ride comfort properties compared to rigid axles offer, such as a torsion crank axle.
  • the first distance is defined as the distance between the pivot point and the bearing area of the wishbones.
  • a projected point in the imaginary extension of the suspension device as a reference point in the respective bearing area is decisive for determining the first distance.
  • a central axis of the suspension device can serve as the geometric center and thus for measuring the first distance.
  • an axis of rotation of the point of articulation can also serve as the geometric center and thus for measuring the first distance.
  • the suspension device has a bending spring which extends essentially in the transverse direction and which is arranged between the axle links essentially parallel to the transverse profile and is designed for support on the chassis.
  • the suspension device can stiffen the vehicle axle in the transverse direction in addition to the suspension of the chassis.
  • the bending spring can in particular be designed as a directly connected transverse leaf spring. Such a design additionally increases the transverse rigidity of the axle, in particular in comparison to the use of coupling rods.
  • FIG. 2 shows a schematic side view of the vehicle axle according to FIG. 1;
  • the vehicle axle 1 here comprises, for example, two axle guides 2, a transverse profile 4 and a common suspension device 6.
  • the vehicle axle 1 is designed in particular as a coupling arm axle for commercial vehicles.
  • FIG. 7 shows a schematic perspective view of a vehicle axle 1 according to a further exemplary embodiment. While in FIGS. 1 to 6 some of the features described are also applied in isolation to the vehicle axle 1, the exemplary embodiment according to FIG. 7 makes it clear that the features described above can also be completely combined with one another. In particular are here an elastomeric bearing 14 with a housing 17 as shown in FIG. 6 and a linear guide system 16 as shown in FIG. 5 combined with a vehicle axle 1 as shown in FIG. Nevertheless, the large number of possible combinations of the described features of the present invention is not limited to this combination by the exemplary embodiment according to FIG.

Abstract

L'invention concerne un essieu de véhicule, en particulier un essieu à poutre de torsion, pour des véhicules utilitaires, comprenant au moins deux liaisons d'essieu qui s'étendent sensiblement dans la direction longitudinale et dont chacune a un point d'articulation pour s'articuler de manière pivotante sur un châssis ; une section profilée transversale qui s'étend dans la direction transversale et relie les liaisons d'essieu entre elles et qui est reliée de manière rigide à chaque liaison d'essieu au niveau d'une zone de liaison transversale respective des liaisons d'essieu ; et un dispositif à ressort qui est monté sur chaque liaison d'essieu dans une zone de support des liaisons d'essieu ; une première distance entre le point d'articulation et la zone de montage des liaisons d'essieu étant inférieure à une seconde distance entre le point d'articulation et la zone de liaison transversale des liaisons d'essieu.
