Definitions

  • the invention relates to a handlebar, for example wishbone arm, in particular for the wheel suspension of a motor vehicle, according to the preamble of patent claim 1.
  • Handlebars of the type mentioned are used in almost all types of motor vehicles and in almost all wheel suspensions of motor vehicles.
  • Such control arms for example wishbones, but also trailing arms, control arms of space control axles and the like have the task on the motor vehicle to connect the respectively associated wheel or the wheel carrier of the associated wheel to the body structure in such a way that the wheel or wheel carrier merely has the degrees of freedom provided by the design remain.
  • wheel guide links are essentially formed in one piece, in particular as one-piece die-forged parts, as one-piece cast components or as one- or two-shell deep-drawn sheet metal components.
  • Wheel control arm is forced to design and manufacture or keep a variety of different wheel control arms.
  • this has the particular consequence that different tools are required for producing the respective wheel control arms for each individual type of wheel control arm. Since wheel control arms are relatively large, but also complicatedly shaped and extremely heavily loaded components made of high-quality and resistant materials, the tools for producing one-piece wheel control arms are usually correspondingly complex, complicated and therefore both expensive and tend to be vulnerable.
  • the handlebar should in particular be simple and inexpensive to manufacture, and the extremely high tool costs for the production of the wheel control arm, which are customary in the prior art, should not be incurred.
  • the wheel control arm should also be able to be manufactured efficiently in relatively small quantities and with high cost-effectiveness, while at the same time if possible short time spans between specification, sampling and production should be feasible.
  • the handlebar according to the present invention comprises, in a manner known per se, at least two attachment points which are movable
  • the handlebar connection of the handlebar on the one hand to a body structure of a motor vehicle and on the other hand to a wheel guide component.
  • the wheel guide component can be, for example, a steering knuckle, a wheel carrier, or a spring strut.
  • the handlebar comprises a strut arrangement.
  • the strut arrangement serves to connect the at least two mounting points of the handlebar.
  • the handlebar is characterized in that the strut arrangement is composed of at least two strut devices.
  • the strut devices are designed as separate profile parts with an essentially flat or open cross-sectional shape.
  • the handlebar does not have a one-piece strut arrangement, but rather the strut arrangement of the handlebar is composed of at least two separate strut devices, the strut devices being in the form of geometrically relatively simple profile parts.
  • the strut devices or profile parts can thus be produced separately from one another by means of relatively simple, standardized and therefore inexpensive tools.
  • the invention in particular also has the decisive advantage that the strut devices, which are in the form of separate profile parts, have no significant change to the profile parts or strut devices, and without any significant changes can be used on the production tools for the strut devices to create a variety of different handlebars.
  • control arms with different geometries, with different dimensions or with different track widths without any modification to the strut devices which the control arms comprise. Rather, the profile parts or strut devices of the handlebar are connected to each other in different arrangements or in different relative positions for the production of such different control arms from unchanged individual parts.
  • the strut devices can be connected to one another in at least two different relative positions or relative angles.
  • handlebars with at least two different geometries or at least two different dimensions can be produced using the same strut devices.
  • handlebars which comprise more than two strut devices which can each be connected to one another in at least two different relative positions or relative angles the number of variants which can be produced in this way increases accordingly.
  • the strut devices can be connected to one another within a range of adjustment in several different relative positions or relative angles.
  • an even larger number of variants of links can be produced with the same strut devices, again without changes to the tools on which the strut devices are based.
  • handlebar designs that have different dimensions, for example different track widths of different types of a motor vehicle series can be set.
  • a basic, arbitrarily large number of different variants of wheel guide links can be produced within a variant range, as is also provided by a further preferred embodiment of the invention, if the strut devices can be connected to one another in an adjustable range in continuously selectable relative positions or relative angles. In this way, fine adjustment of the axle geometry or the track width, for example, can also be carried out on the basis of corresponding changes in the relative position of the strut devices of the handlebar.
  • the handlebar has a latching device with a plurality of latching steps which snap in resiliently or elastically.
  • the latching device By means of the latching device, the strut devices can be brought into position with respect to one another at predetermined intervals before the strut devices are finally connected to one another.
  • Such a locking device facilitates the assembly of the strut devices and leads to better reproducibility of the intended relative position of the strut devices within a handlebar design.
  • connection of the individual strut devices it is initially not essential in what way the connection of the individual strut devices and thus the final determination of the geometry, design and dimension of the handlebar is finally carried out, as long as the connection can withstand the loads occurring during the operation of the handlebar.
  • the individual strut devices can thus be connected to one another in particular in a force-fitting, form-fitting or material-locking manner.
  • Strut devices releasably connectable. This is advantageous both with regard to a subsequent adjustment of the relative position of the strut devices, For example, for a change in the track width or the axle geometry, as well as in relation to the repair of the handlebar or the replacement of individual handlebar components or strut devices due to damage or wear.
  • the strut devices of a handlebar are integrally connected to one another.
  • the cohesive connection of the strut devices, in particular the welding, is to be used with advantage if a subsequent change in the geometry or dimensions of the handlebar is out of the question, which is the case, for example, in the series production of a certain handlebar design for a certain motor vehicle.
  • the strut devices are caulked to one another without filler material.
  • This type of connection of the strut devices is particularly advantageous, since neither a tendentially harmful thermal load on the components as occurs during welding, nor does it require the production of relatively complex screw or rivet connections.
  • the strut devices are connected, for example, by the so-called toxin, in which the metal sheets to be connected are connected by means of a special
  • Tool rivet-like by means of punctiform interlocking forming but are connected to each other without additional material.
  • the caulking can also be carried out without filler material, for example in the form of the known flanging or clamping.
  • the strut devices are positioned relative to one another before the final connection of the strut devices is established.
  • at least two strut devices of the handlebar can be pushed into one another in the manner of a link or telescope.
  • this design facilitates the pre-assembly and pre-fixing of the strut devices before they are finally connected to one another.
  • the strut devices can be brought into different relative positions in the simplest possible way, so that handlebars with different geometries or different dimensions can be produced in a simple manner.
  • the link-like or telescopically insertable shape of the profile parts forming the strut devices also increases the bending and torsional rigidity and the buckling strength of the strut or strut arrangement thus formed.
  • Strut devices of the handlebars telescopically or telescopically along a circular arc.
  • this design also has the advantage that curved handlebar geometries and more complex adjustability of a handlebar can also be represented in this way.
  • At least two strut devices are connected to one another by means of interlocking press-in collars.
  • This type of connection of the strut devices is particularly advantageous in that the press-in collars or
  • Press-in openings can be produced extremely easily by deep drawing, and as a result, a connection of the strut devices that is both extremely robust and also particularly easy to manufacture and additionally adjustable in angle is made possible.
  • At least two strut devices are by means of at least one further strut device connectable with each other.
  • at least two strut devices are by means of at least one further strut device connectable with each other.
