Three-point connecting rod

Abstract

The invention relates to a three-point connecting rod having two connecting rod arms (13) which are at an acute angle to each other and which intersect at one end in each case in an intermediate joint (11),-wherein the intermediate joint (11) has a cylindrical dome (17) extending in an axial direction (a), the central joint (11) has an axial direction which extends at least substantially perpendicular to a plane expanded by the two link arms (13),-wherein the central joint (11) has a joint ball (18) which is penetrated by the dome (17),-wherein the central joint (11) also has a retaining means (19) which acts as a stop in order to prevent the central joint from being completely separated, and-wherein the central joint (11) has an axial direction which extends at least substantially perpendicular to the plane expanded by the two link arms (13). The retaining element (19) extends in a radial direction (r) oriented perpendicular to the axial direction (a),-wherein the retaining element (19) is likewise penetrated by the dome (17) and is fixed simultaneously by an annular stop element (20) against axial removal from the dome (17),-wherein the retaining element (19) is fixed in the radial direction (r) in the radial direction (r), and-wherein the retaining element (19) is fixed in the radial direction (r) in the radial direction (r) in the radial direction (r) in the radial direction (r) in the radial direction (r). The annular locking element (20) is arranged on the side of the retaining protector (19) facing away from the joint ball (18) when viewed in the axial direction (a) and engages in an annular groove (21) of the dome (17) at the same time. The invention is characterized in that the annular stop element (20) is surrounded by the retaining means (19) in the radial direction (r) in a contact manner, so that the annular stop element (20) is prevented from disengaging from the annular groove (21) of the dome (17), as the annular stop element (20) cannot move out of the annular groove (21) of the dome (17) in the radial direction (r).

Description

technical field [0001] The invention relates to a three-point linkage according to the preamble of claim 1 . Background technique [0002] Axle suspensions of utility vehicles, for example for commercial freight or passenger transport, usually have a rear axle configured as a rigid axle. Such a rigid shaft can be guided by a three-point linkage, which is arranged above the rigid shaft in the upper linkage plane. Such a three-point linkage has two linkage arms which enclose each other at an acute angle and which simultaneously each meet with one end in a first bearing point. In this first bearing point, the three-point linkage is connected to the rigid shaft body of the rigid shaft via an intermediate joint, wherein the intermediate joint is assigned to the three-point linkage and is configured as a ball joint. The other two ends of the three-point linkage are each connected to the vehicle frame via a guide joint, for example a so-called molecular joint. The intermediate j...
