Definitions

  • the invention relates to an axle or a subframe, also called subframe, for the front axle of motor vehicles.
  • an axle carrier has become known with lateral side members, wherein on each longitudinal member a bearing block for receiving a link of the vehicle chassis, as well as between the longitudinal members a planar stiffening element is provided.
  • This stiffening element extends from one to the other of the two trailing arms and is detachably connected thereto.
  • axle carrier have the disadvantage that they are composed of a variety of items to which - before or after the assembly of these items - even the connection points for the body connection and for various units, such as the engine, the handlebars and so on are attached usually, by welding.
  • the present invention has for its object to produce such Achs nave rational and cheaper to save weight, increase the stiffness and at least to form integrally one of the connection points in order to reduce the assembly costs on.
  • the axle according to the invention is characterized in that at the end regions of two lateral side members are integrally provided with these integrally formed connection points for attachment of the axle carrier to the body and that a flat and from the body attachment points and the Longitudinal braces distant stiffening element is provided, which is in turn integrally connected to this integrally formed cantilever in one piece with the body connection points.
  • axle carrier can be produced in a particularly simple and rational manner from light metal alloys, in particular an Al alloy, in particular by die casting.
  • the stiffening element can advantageously be quadrangular, wherein it has proven to be particularly advantageous in terms of optimization of stiffness, if this stiffening element by at least one extending between the transition regions of the stiffening element in the two forward in the direction of travel boom rib in two fields - one in the direction of travel at the front and one behind it - is divided. It has proved to be particularly advantageous if at least one of the fields has a curvature downwards, ie in the direction of the roadway, wherein it has again proven to be advantageous when the curved field is the front. Furthermore, it has proven to be advantageous if the reinforcing rib is also directed upward.
  • each bodywork connection point seen in the direction of travel, each having an upwardly directed and longitudinally oriented forwardly formed integrally therewith, wherein each body attachment point has at least two fastening points spaced apart from each other via a bridge.
  • These essays are suitably connected to each other via a cross member, which is integrally formed with the essays.
  • the axle according to the invention further has in addition to the attachment sites for attachment to the body also integrally formed connection points at least for the engine, the wishbone and the steering gear.
  • FIGS. 1 to 3 The invention will be explained in more detail with reference to FIGS. 1 to 3:
  • FIG. 2 shows the axle I in another view from above with the specified direction of travel F and
  • Figure 3 shows the axle beam I from below with the direction of travel in the direction of arrow F.
  • a planar stiffening element 7 Spaced from the longitudinal beams is a planar stiffening element 7, which is spaced from the longitudinal beams 1, 2, but integrally connected to the trailing arms 1.2 via front boom 8.9 and rear boom 10,11 integrally connected to the trailing arms or the body attachment points.
  • the stiffening element 7 is divided by an upwards, ie away from the roadway, directed rib 13 practically in two fields 14,15, which are formed like a dome, the curvature directed downward towards the roadway.
  • reinforcing element 7 is surrounded by reinforcing ribs, namely a front 16 and two each provided on the left and right Verstärkungsrip- pen 17,18 and 19,20, and with reinforcing ribs 21 between the two rear "legs" of the x-shaped stiffening element 15th
  • transition regions of the stiffening element 7 in the arms 8 to 10 are denoted by 22,23 and 24,25.
  • openings 26,27 are provided, which are surrounded by upwardly directed reinforcing ribs 28,29.
  • the front body attachment points 3 and 4 are each formed by an integrally formed with the longitudinal members 1.2 essays, which protrude upward, ie away from the roadway. They each have two attachment points 32,33 and 34,35, which are spaced apart and connected to each other via a bridge 36,37.
  • the connection points 3, 4 are connected to one another via a cross member 38, which likewise is in one piece or in one piece with the two connection points.
  • the axle carrier further has integrally formed on these attachment points 39,40 and 41, 42 for the wishbone, 43,44 for the engine and connection points 45,46 for the steering gear.
  • the axle carrier according to the present invention can be produced easily and torsionally rigid by producing it from a light metal alloy, such as, in particular, an Al alloy and particularly cost-effectively in the die-casting method.
