Definitions

  • the invention relates to a front axle for a motor vehicle and a method for its production.
  • Vorderachs be known among other things as a subframe or subframe, or generally as a stool or frame. They serve to accommodate wheel control arms and other aggregates and auxiliary units and are used as preassembled units or modules on the vehicle body, e.g. attached to the body and / or L Lucassträgem of the vehicle.
  • the front axle carrier generally has on each of its two sides a receptacle, each receptacle for each of the bearings of one of the two Rad Equipmentslenker, such as. a wishbone, wishbone or semi-trailing arm is provided. Furthermore, e.g. Recordings for mounting a steering gear, the stabilizer and other units formed.
  • a front axle carrier is e.g. shown in DE 199 20 051 A1.
  • DE 10 2006 042 377 A1 shows a front axle, which has receptacles or recesses for attachment of the steering gear, the stabilizer and the bearing of a pendulum support and is made in one piece with these receptacles and recesses made of light metal.
  • the production as a one-piece die-cast part basically allows a quick production with a few process steps, eg. B. only one casting process with post-processing. However, such systems provide a high overall weight and high material costs.
  • the invention has for its object to provide a front axle for a motor vehicle and a method for its production, which allow cost-effective production with little effort in a stable training and the connection of various components.
  • a middle cross member is thus produced separately from the outer consoles and these components are subsequently connected to each other, preferably welded, possibly also screwed.
  • the two side brackets can be designed in particular as castings cost with a stable structure and low weight.
  • the separate production of lateral brackets independent of the central cross member allows this greater freedom in shaping, both with respect to the formation of shots and with respect to the rigidity of ribbing, etc.
  • the consoles preferably have recordings for attachment to the vehicle and bearing receivers for Rad Installationslenker on.
  • the middle cross member is formed as an extruded profile having a double-walled area.
  • the double-walled region in this case allows a high rigidity, preferably extending at least one cavity in the transverse direction through the cross member.
  • the double-walled area is angularly formed with a front horizontal web and a subsequent vertical web.
  • a wall is formed between the front horizontal double-walled web and the vertical web.
  • a single-walled rear area is formed by the extrusion profile is subsequently deformed.
  • the cross member is therefore designed as at least partially separated and / or at least partially unwound extruded profile.
  • the extruded profile is formed with a rear closed area, the is subsequently separated, whereupon this area is handled.
  • an upper, substantially horizontal surface and a lower, substantially horizontal surface are formed, between which a pendulum support receptacle as e.g. cylindrical sleeve can be introduced.
  • the cutting guide may be chosen such that the upper horizontal surface tapers laterally outward from a central region, i. in the middle region has a greater longitudinal extent to accommodate the pendulum support receptacle in the upper region, and form in the lower surface after settlement lateral regions obliquely rearwardly projecting tabs for connecting the consoles.
  • the double-walled, preferably L-shaped region ensures high rigidity.
  • the settlement by e.g. one or more severance lines - according to the invention a single separation line is possible - can be done in a simple cutting or punching process step, whereupon the settlement takes place as a shape of the rear flaps.
  • the front axle is at least predominantly made of a light metal, preferably made of aluminum or an aluminum alloy.
  • a light metal preferably made of aluminum or an aluminum alloy.
  • Fig. 1 a front axle according to the invention in perspective
  • Fig. 3 shows the extruded profile indicating the separation line
  • FIG. 4 to 6 different perspective views of the cross member produced by subsequent development of the extruded profile, wherein in addition to the illustration in the figures, the extruded profile is shown in the figures.
  • a front axle carrier 1 shown in FIG. 1 is made of a light metal, in particular aluminum or an aluminum alloy, and has a cross member 2 and two lateral brackets 3 and 4.
  • a pendulum support receptacle 5 is formed, preferably as a substantially vertically extending cylindrical bearing mount.
  • brackets 3, 4 are upwardly extending boom 6, 8 with receptacles 9, 10 for attachment of the front axle 1 on the vehicle, further front bearing receivers 11, 12 are formed for Rad Equipmentslenker of the vehicle and rear bearing receivers 14, 15 for the wheel bearing.
  • the lateral brackets 3, 4 are formed as castings, optionally with appropriate post-processing to form the individual recordings.
  • the cross member 2 has a front double-walled area 20, which by a double-walled front, horizontally extending web 21st and a back-connecting, double-walled, vertically extending web 22 is formed.
  • a wall 23 extends between the webs 21 and 22, so that two cavities 24 and 25 are formed with, for example, a minimum thickness of 9 mm.
  • a lower horizontal surface 30 at the double-walled region 20 close to the rear of a single-walled, upper horizontal surface 28 and parallel to this, a lower horizontal surface 30 at.
  • a circular recess 31 is formed, in which an upper end of the pendulum support receptacle 5 is welded.
  • the upper horizontal surface 28 extends rearwardly substantially in the central region to enclose the circular recess 31.
  • the lower horizontal surface 30 extends further to the rear and comprises two lateral tabs 34, 35, to which rear portions of the brackets 3, 4 are welded.
  • clearances 36, 38 between the cross member 2 and the brackets 3, 4 are formed because these areas are not so heavily loaded and thus free space 36, 38 material can be saved.
  • the pendulum support is advantageously further welded to the vertical web 22.
  • the pendulum support receptacle 5 extends longitudinally forward a recess 40, e.g. for an output shaft.
  • the entire front axle 1 can be designed symmetrically or substantially symmetrically, wherein the exact geometric shape of the lateral position of the pendulum support receptacle 5 can be adjusted, which can be provided slightly off-center in the lateral direction.
  • the cross member 2 according to the invention can be produced in a surprisingly simple, cost-effective manner as unwound extruded profile.
  • This will be first the extrusion profile 42 shown in Fig. 2, 3 produced as a profile strand of aluminum by cutting.
  • the extruded profile 42 already has the double-walled region 20, which is adjoined by a closed region 44 towards the rear.
  • the extrusion direction in the production of the extruded profile 42 is thus with respect to the later installation position in the vehicle transverse direction or Y direction.
  • the size and shape of the closed region 44 is thereby adapted to the desired shape of the subsequently produced upper and lower horizontal surface 28, 30.
  • the closed region 44 is separated by a suitable cutting guide along the splitting line 46, which is shown in FIGS. 3 to 6. It extends on the upper side of the closed region 44 from the laterally outer regions substantially in the transverse direction or extrusion direction toward the center and then obliquely rearwardly to form the wide region for receiving the recess 31 for the pendulum support receptacle 5. Laterally, the separation line 46 extends vertically downwardly through the double-walled vertical web 22, wherein subsequently in the lower horizontal surface 30, a desired shape is formed with lateral tabs 33 projecting slightly outwards. Of the front flaps 33, the severance line 46 extends rearwardly and toward the center to form the clearances 36, 38, and then rearwardly and outwardly toward the shape of the rear flaps 34, 35.
  • the separation along the Trennline 46 can be done by punching or cutting.
  • the appropriately separated and cut extruded profile 42 is unwound, for which, according to the arrow P, the rear part of the closed area 44 is unwound or folded back.
  • the tabs 34, 35 can be formed with suitable shaping, for example with bends 34a, b and 35a, b.
  • holes 50 and the circular recess 31 are formed, which also already formed together with the separation line 46, z. B. can be punched.
  • the Pendel neutral tone quality 5 is advantageously set after the settlement between the upper and lower surface 28, 30 and welded, for example by laser welding.
  • the recess 40 is formed, for example milled.
  • the cross member 2 according to the invention is inexpensive to produce in a few process steps. It is subsequently connected to the two brackets 3, 4, for example by welding and / or by screws set in the holes 50.
