Definitions

  • a three-point link of the type mentioned is known from FR 2 932 415 A1.
  • a three-point link which comprises a two-piece central housing with two housing parts for receiving a central joint in one of the two housing parts formed receiving opening Ge.
  • the central housing connects two control arms, which are positioned at an adjustable angle to each other.
  • the two housing parts and the two control arms are formed in one piece.
  • a disadvantage of the prior art is that when the extent of the link arms is adjusted in the longitudinal direction of the vehicle by varying the length of the link arms, various components must be manufactured and stored in order to be able to provide different vehicle and kinematic-related geometries of the three-point link.
  • a chassis arrangement in which at least one three-point link according to the invention is used is also the subject of claim 15.
  • a three-point link is proposed, comprising a two-part central housing with two housing parts for accommodating a central joint in a receiving opening formed by the two housing parts, the central housing connecting two control arms with one another, which are positioned at an adjustable angle to one another.
  • the housing parts are designed as identical parts with at least three axially spaced lamellae, which are assembled in a plane extending perpendicularly to the vertical axis of the central joint in an upturned manner and, in particular detachably, are non-positively connected to one another, and that the respective Housing part is set up for connecting the control arm, which is designed as a separate component.
  • the design of the housing parts as identical parts according to the invention reduces the required manufacturing effort for a wishbone.
  • the provision of at least three slats, which are fitted into one another on an envelope, contributes to improved power transmission if, after the angle has been set, the slats are non-positively connected to one another. It is particularly advantageous that the angle can be continuously adjusted.
  • the design of the link arms as separate components that are to be connected to the respective housing part increases flexibility when adapting three-point links to different vehicle and kinematics-related geometries.
  • a sleeve with a radial outer flange can be arranged in the receiving opening, which is supported on the surface of a housing part.
  • the sleeve serves to accommodate components of the central joint and to attach it to the central housing.
  • the fixing of a set angle of the link arms to one another can be effected.
  • the sleeve can have a fastening section on its free end facing away from the outer flange, which is used for the detachable axial fixing of the sleeve on the central housing.
  • the fastening section can preferably be designed as an externally threaded section, which serves to accommodate a fastening element.
  • the fastening element is essentially ring-shaped. By means of the fastening element, the sleeve can be fixed to the central housing by clamping in the axial direction.

  • the essentially circular-cylindrical central housing forms the radially outer end faces of the superimposed lamellae.
  • a non-positive or materially bonded connection of the lamellae to one another can be provided by gluing.
  • the angle can be freely adjusted so that it is only fixed after an adhesive has hardened. Irrespective of the type of connection of the slats to one another, an angle between the link arms can be adjusted purely frictionally, without a form fit in the circumferential direction of the housing parts.
  • the axial distances between the lamellae can be chosen such that when the housing sections are assembled, the contact surfaces of the middle lamellae lie essentially in a plane with an equator of a joint ball of the central joint designed as a ball joint.
  • a central plane of the housing parts extending in the vehicle longitudinal direction and vehicle transverse direction, which runs between the contact surfaces of the central slats, can essentially lie in the plane of the equator, so that a central offset in relation to the joint ball is minimal. Due to the minimized center offset, an uneven load on the link arms is avoided when the central joint absorbs tensile and compressive forces.
  • the spaces between the lamellae can have a radial extent that is greater than the outer diameter of the housing parts in the area of the receiving opening.
  • the housing parts can each have a connecting section, which is used to arrange the separate link arms by means of a non-positive and/or positive and/or material connection.

  • the rigid axle is pulled by a V-shaped spread axle guide link that extends essentially in the vehicle longitudinal direction x and is designed as a three-point link 5 .
  • the three-point link 5 is also referred to as a triangular link because of its specific geometry.
  • the three-point link 5 is designed symmetrically in relation to a plane that is spanned by the vehicle longitudinal direction x and the vehicle vertical direction z, and has two joints 15 arranged at the ends of the link arms 12, via which the three-point link 5 is connected to the cross member 3 is.
  • the three-point link 5 has a central joint 11 designed as a ball joint 22 with a central housing 13 for the rotatable and pivotable connection of the three-point link 5 to the rigid axle body 2 .
