Definitions

  • the invention relates to a guide device for a motor vehicle rigid axle with at least three trailing arms, wherein two wheel-guiding trailing arms of the same link plane are coupled between their articulation points on the body side, while they each guide the rigid axle via a multi-axis joint.
  • Such a guide device is known from DE-OS 25 05 124.
  • the triangular link coupling axle shown has two parallel, rigid axle-carrying trailing arms which are coupled on the body side between the articulation points there by means of a continuous cross member.
  • the trailing arms and the cross member form a U-shaped component that has a torsionally soft constriction in the central area.
  • the component also has the function of a U stabilizer.
  • This handlebar combination has the advantage that it is articulated only at two points on the vehicle body in addition to a support strut which prevents the axle body from rotating.
  • This construction is only suitable for relatively light, off-road vehicles.
  • the cross member bends at its narrow point under plastic component deformation.
  • the present invention is therefore based on the problem of creating a guide device for a motor vehicle rigid axle which, independent of a stabilizer and / or a support strut preventing the rotation of the axle body, with good off-road mobility and small structural dimensions, has large longitudinal and transverse forces in only two articulation points on the vehicle body or frame can transmit.
  • the problem is solved with the features of the main claim.
  • the wheel-guiding trailing arms of the handlebar level are coupled between the articulation points via a coupling joint.
  • the coupling joint lies, for example, centrally between the articulation points on the body side. It is designed as a ball or universal joint to absorb large forces with at least four degrees of freedom.
  • a translational degree of freedom of the coupling joint which allows the handlebars to be displaced vertically relative to one another in the millimeter range, prevents the handlebars from being twisted or twisted.
  • Figure 1 wishbone-guided rigid axle
  • Figure 2 Axle joint between a wishbone and the rigid axle
  • Figure 3 Coupling point of the wishbones.
  • Figure 1 shows schematically a steerable rigid axle. Axle guidance is provided by four trailing arms (11, 12 and 42, 43) arranged in two levels (10, 40), which connect the rigid axle body (2) to the vehicle body (5).
  • the rigid axle body (2) is supported on the vehicle body (5) by means of air bellows (3).
  • Wheel-bearing steering knuckles (6) are arranged at its free ends. The latter are coupled to one another, for example, via the tie rod levers (7) and a tie rod (8).
  • each trailing arm (11, 12) is essentially a triangular component that carries a joint (31-35) in each corner.
  • the trailing arms (11, 12) are preferably made of light metal. This reduces the unsprung mass and thus improves driving dynamics.
  • each handlebar can e.g. a framework, a sheet metal construction or a combination thereof.
  • each handlebar (11, 12) includes three - each forming a flat triangle - struts (13-15, 16-17).
  • the struts (13-15, 16-17) each have a rectangular profile as an example.
  • hollow tube profiles or profiles with a T, H or V cross section can also be used.
  • Short cantilever arms (21) are attached to the rigid axle body (2), at the ends of which the articulation points for the individual trailing arms are located.
  • the centers of the joints are usually below or above and in front of or behind the center line of the rigid axis.
  • the elastic joints (31, 32) lying below the center line in FIG. 1 have, for example, transverse pivot axes (49), cf. Figure 2. They exist - like the joints (33) and (34)
  • Hinge pin (22) The latter is attached via a side surface to two cantilever arms (21) projecting from the rigid axle body (2).
  • the joint ball (23) is from one to the
  • a jointed-in rubber element (25) sits, for example, in the joint eye (24) and the joint ball (23).
  • Swivel angle of ⁇ 15 ° too Furthermore, it allows swivel angles of several degrees about its vertical and transverse axes, the latter being parallel to the longitudinal axis of the vehicle, the maximum swivel angle about the transverse axis also being able to be up to 30 °.
  • An elastic transverse offset along the center line (49) is also possible in the tenth of a millimeter range.
  • the joints (31-34) are primary
  • the hinge pins (22) of the joints (33) and (34) are attached to the vehicle body (5).
  • the struts (15) and (18) are aligned here.
  • the joint eye (29) lined with an elastic material and the fork head (27) are coupled via a joint bolt (26) provided with a joint ball (28).
  • the coupling joint (35) thus formed largely corresponds to the joints (31-34) in terms of its structure. However, its center line is aligned approximately parallel to the vertical axis of the vehicle and allows an elastically resettable stroke of approximately ⁇ 1 mm along the center line.
  • a U-stabilizer (41) is shown schematically above the lower trailing arms (11, 12). It lies in an upper link plane (40) which is approximately parallel to the plane (10).
  • the U stabilizer consists of two trailing arms (42) and (43), which are connected via a transverse bar (44) or a comparable component.
  • the trailing arms (42, 43) are mounted on the axle side, for example via ball joints (36, 37) on the rigid axle body (2), while they are supported on the body side in swivel joints (38, 39).
  • the cantilever arms (21) which support the ball joints (36, 37) are generally longer than the cantilever arms which bear the joints (31, 32) and are directed downward.
  • the trailing arms (42, 43) are preferably designed as approximately flat, torsionally soft plates, the vertical dimension of which is significantly greater than the transverse dimension. This design means that they are stiff in the longitudinal direction of the vehicle and flexible in the transverse direction of the vehicle.
  • handlebar planes (10) and (40) can also be interchanged, so that, for example, the stabilizer (41) lies below the trailing arms (11, 12).
  • the lower trailing arms (11, 12) guiding the rigid axle transmit the longitudinal forces from the rigid axle body (2) to the vehicle body (5) or the vehicle frame via the struts (13) and (16).
  • the lateral forces acting on the rigid axle are introduced into the struts (14) and (17) as opposing supporting forces in the central coupling joint (35) and are supported as reaction forces via the struts (15) and (18) on the vehicle body (5).
  • the trailing arms (11, 12) twist due to the inclined position of the rigid axle beam.
  • the trailing arm of the rebounding axle side swings down and the longitudinal member of the rebounding side upwards.
  • the joint eye (29) and the fork head (27) rotate in the transverse direction of the vehicle.
  • the shortest distance between the coupling joint (35) increases compared to a connecting line between the joint parts (31) and (32), as a result of which the struts (15) and (18) enclose an obtuse angle.
  • tensile forces act on the coupling joint (35) in the transverse direction of the vehicle.
  • axis-side joints (31, 32) are primarily axis-parallel swivel joints, they are pivoted slightly around the connecting line (31, 33) or (32, 34) when the rigid axle body (2) is inclined. Consequently, in the coupling joint (35), the joint eye (29) and the fork head (27) are displaced relative to one another within the framework of the elastic joint compliance.
  • the fork head (27) or the joint eye (29) can be supported in the z direction on the vehicle body.
  • the fork carriage for example, is attached to a hinge part (51) via a rod, cf. Figure 1, articulated.
  • the fork head (27) can just as well be gripped elastically on its upper and lower sides, the gripping being fastened to the vehicle body.
  • the trailing arms (11, 12) can be braced against each other.
  • individual disc springs, stack of disc springs or disc spring assemblies can be installed between the fork head (27) and the joint eye (29). The springs hold the trailing arms (11, 12) in one plane due to the bracing.
  • a leaf spring or leaf spring combination guided along the struts (15) and (18) has a comparable effect.
