Description

The invention relates to a support structure of a motor vehicle according to the preamble of Claim 1.

A known generic support structure of a motor vehicle in the manner of a grid frame (EP 0 146 716 B1) consists of light metal cast knots and connecting them Extruded light metal profiles. There are many different light metal cast nodes with many smaller and larger light metal extruded profiles connected. This results in a relative large manufacturing and assembly costs with complex welding measures and from them resulting, relatively large dimensional tolerances.

The light metal cast knots are in a known manner in a high die casting process, a so-called vacuum process. With this casting process very high pressures occur, which are controlled with large hydraulic cylinders, but what the die casting machines and thus the producible light metal casting knots are limited in their dimensions. The manufacturability of the light metal casting Knot therefore has a decisive influence on the design options Quality, the weight and the price of the known support structure of a motor vehicle Light alloy.

From DE 44 23 642 C1 it is known to have a supporting frame in a half-timbered construction (integral Lattice frame structure) from frame profile parts on the one hand and fiber composite nodes on the other hand to build up. The fiber composite nodes can either be one contain thermoplastic or a thermosetting matrix. The frame profile parts are preferably formed as a rectangular hollow profile, either from one Fiber composite material with or from a thermoplastic matrix Fiber composite material with a duromer matrix or a metallic one Material.  

It is already known in the front of a car body for a passenger car use a one-piece, stable wheel arch liner on both sides (DE 195 43 193 C1), whereby partially stiffening sections are integrated in the wheel arch liner. Such one-piece, stable wheel arch liners are only used in the front of the car body in conjunction with a usual sheet steel body used. It is also without further input Zelheiten mentioned that such wheel arch liners made of light metal with shots Bracket and attachment of functional elements can be produced. Such a wheel Running shell made of light metal thus only represents a body part in the stem of one Body, which is in a composite construction otherwise in a conventional steel sheet metal structure is constructed.

In a known low-pressure casting process for light alloy wheels (DE 94 21 365 U1) the solidification process starts from opposite the feed point for the melt remote places controlled controlled. This is achieved by using selective cooling predetermined cooling rate compressed air through cooling channels of a corresponding mold guided. This is in connection with an inexpensive low pressure process Relatively thin wall thicknesses can be achieved to save weight. In addition, achieved a homogeneous and void-free structure of the cast body.

A casting method for thin-walled castings made of ferrous materials is also known (DE 42 38 753 A1 ), in which a mold up to just below the solidification temperature of the The melt is preheated and a controlled temperature after the introduction of the melt raturführung for cooling takes place.

Next are pressure and / or low pressure casting processes and corresponding molds known (DE 42 25 879 A1; DE 43 13 836 A1) with arrangements of temperature sensors and / or pressure sensors, the casting process also relating to the pressure and / or Temperature control is performed controlled.

The object of the invention is a generic support structure of a motor vehicle to further develop that these are built in a low-weight manner and can be produced with little effort and is mountable.  

This object is achieved with the features of claim 1.

According to claim 1 are as light metal cast knots and / or plastic knots at least four large-volume, one-piece base node elements are provided, of which two each opposite each other in the area of the front end and two on each side are arranged opposite each other in the area of the rear end. These four Base node elements are made of molded connecting parts with extruded light metal profiles and / or plastic profiles as connection carriers to a base frame put together and connected.

With this construction, a dimensionally stable can be easily and quickly with few components Base frame are built, which then with the other body components and Functional elements can be equipped and supplemented. By saving one more number of light metal cast knots and / or plastic knots in the area of large-volume, one-piece base node elements, the overall arrangement is less expensive.

This makes light, inexpensive and environmentally friendly passenger cars with little Fuel consumption can be produced.

Carrier parts and / or can be particularly advantageous in such one-piece base node elements Wall parts and / or reinforcing ribs and connecting parts for connecting beams and / or functional parts can be integrated.

In this case, a lower one can advantageously in each case in the front-end base node elements Longitudinal member, a strut tower and attachment points for the front axle can be integrated, which eliminates their separate training from a plurality of individual components. Further can advantageously be a curved girder ver in each of the front car base node elements Binding from the lower side member to a molded sill connector inte be griert.

Likewise, the front-end base node elements can each have an integrated vertical carrier, preferably next to the area of the rocker connector, with a have upper A-pillar connector. An integrated upper one can advantageously be attached to this  Connect the side member on which, for example, in an approximately horizontal A strut dome is formed in the U-shaped region. Other connectors and brackets for beams and functional elements, especially laterally for fastening cross beams profiles in the tunnel and cowl area and for fastening gearbox bearings and / or Anti-lock devices and / or engine mounts are possible and depending on the specific structure construction can be used advantageously. The cross member profiles can be in a simple overall arrangement similar to a subframe steering gear, pendulum supports or units for one Wear power steering.

The rear car base node elements are advantageously corresponding to the front car base node elements constructed, the rear car base node elements each one Integrated lower longitudinal member, a strut tower and stops for the Have rear axle. Also here are vertical support parts, sill connection parts, Wheel housing connection parts and in particular C-pillar connection parts can be integrated.

Both the front end base node elements and the rear end base node element elements advantageously have integrated, thin-walled wall areas at least as partial ones Areas of the wheel house. This results in a low-weight, stable stiffening of the Basic node elements with low weight achieved with the function of a one-piece, stable wheel arch liner.

The wall areas of the base node elements on support parts, wall parts, reinforcement Ribs and connecting parts should be as thin-walled as possible with wall thicknesses of preferably approx. Be made 2 mm. On the one hand, these thin wall thicknesses are in a suitable arrangement of the integrated elements sufficient for the required stability and lead on the other hand at cheap, low weights.

Such thin-walled light metal cast base knot elements are advantageous by easy-to-use low-pressure casting process. It is in one to approximated to the melting temperature of the light metal heated mold Solidification of the melt is delayed by controlled cooling in such a way that Solidification fronts from the most distant cast body ends Walk slowly to the center of the casting.  

Casting molds with heating and cooling elements as well as the necessary sensors and controls stanchions are known per se.

The support structure of a motor vehicle according to the invention can also be used using Plastic nodes and / or plastic profiles are built. From economic and ecological reasons are preferred for the plastic knots as basic knot elements thermoplastic materials used, but there are also thermosetting Plastics in question. Can be used to achieve higher strength and rigidity Fiber composite materials are used. The plastic knots are preferred in the inexpensive injection molding process, whereby to achieve the often required complicated shape injection molds with movable slides are used can come. Plastic knots are also preferred (due to the larger ones Stiffness and strength of metal materials compared to plastic materials) Combined light metal extrusions; in principle, however, (especially in Areas with less mechanical stress) plastic profiles used become.

The motor vehicle support structure according to the invention is preferred with a Outer skin cladding made of metal sheets, especially light metal sheets, provided Metal sheets have greater rigidity, strength and UV light resistance than Have plastic panels. Basically, it is especially in areas with less mechanical stress and / or in areas protected from sunlight also possible to use planking made of plastic panels.

The invention is explained in more detail with reference to a drawing.

Show it:

Fig. 1 is a side view of a left front body-base junction element,

Fig. 2 is a view of the base node element of FIG. 1 in the vehicle longitudinal direction, and

Fig. 3 is a plan view of the front body-base junction element according to FIGS. 1 and 2.

A support structure for a motor vehicle, not shown here, has four large-volume, one-piece base knot elements 1 as light metal cast knots (made of aluminum and / or magnesium and / or their alloys), two of which are laterally opposite in the area of the front end and two are laterally opposite are arranged in the area of the rear carriage. These four base node elements 1 are each connected and connected via molded connection parts with light metal extruded profiles to form a base frame, also not shown here.

In Figs. 1 to 3, a left front body-base junction element 1 2 is shown as an example 1, in which FIG. Is a side view, Fig. Is a view in the vehicle longitudinal direction, and Fig. 3 shows a plan view of the front body-base junction element 1.

This front end base node element 1 comprises, as can be seen in particular from FIG. 3, an integrated, lower longitudinal member 2 , each having at its free ends a connecting part 4 for connecting the lower longitudinal member 3 as a light metal strand profile. These connection parts 4 are designed so that they can be inserted in a form-fitting manner in the end connection openings of the lower longitudinal members 3 .

Next, as can also be seen from FIG. 3, in the front-end base node element 1, a curved carrier connection 5 is integrated, which extends from the lower longitudinal member 2 to a molded-on sill connector 6 . A sill 7 is connected to this sill connection 6 , as can also be seen from FIG. 1.

Furthermore, a vertical support 9 is integrated in the front-end base node element 1 . As can be seen in particular from FIG. 2, this vertical support 9 extends vertically upwards from the area of the connection sill 6 . At an upper vertical support end 10 , as can be seen from FIG. 1, an integral A-pillar connection part 11 is formed. At this A-pillar connector 11 a ver A-pillar 12 is connected to the roof.

As can be seen in particular from FIGS. 1 and 3, in the area of the A-pillar connecting part 11 there is an upper longitudinal beam piece 13 which is also integrated into the front-end base node element 1 . At a free longitudinal member end 14 of the upper longitudinal member 13 , an upper longitudinal member 15 is connected to a connecting part 16 .

To form a spring strut dome 17 , the upper side member 13 has a horizontally lying, U-shaped section 8 in the region of the free side member end 14 .

In addition, breakpoints 18 , 19 for the front axle are integrated on the front car base node element 1 . A cross member 20 is screwed on as a subframe in the area of these axially stopping points 18 , 19 , as shown in broken lines in FIG. 1. This cross member 20 , which is designed as an angular profile, causes additional stiffening of the body Ver and can carry steering gear, pendulum support and an electrical and / or hydraulic unit for the power steering. Likewise, knot element 1 brackets and connecting parts for gearbox bearings, anti-lock devices and engine mounts can be provided on the front car base.

As Figs. 1 and 3 and 2 it can be seen, in addition to the cross member 20, a cowl cross-member 21 in the region of the A-column connecting part 11 and a tunnel cross-member 24 to a connecting part 25 in the region of the support points 18, 19 connected. Further, in the area of the axially stopping points 18 , 19 a further angular cross member profile, not shown here, can be attached which, like the cross member 20, additionally stiffens the body and can carry functional elements.

The front end base node element 1 is thin-walled to reduce weight in substantial loading, z. B. with a wall thickness of 2 mm. To reinforce the structure, reinforcing ribs 22 are therefore formed on the front base element 1 , as can be seen in FIG. 1.

Furthermore, the front-end base node element 1 has integrated, thin-walled wall areas 23 which partially form wheel house wall areas.

The rear carriage base node elements, not shown here, and the right front wagon base node element have basically the same structure.

For producing the base node elements of a motor vehicle with small wall thicknesses and high ductility, a low pressure casting process is used. It is in one to  the mold approximates the melting temperature of the light metal rigidification of the melt delayed by controlled cooling. As a result, the migrate Solidification fronts from the most distant cast body ends slowly towards the center of the casting.

Aluminum is preferably used as the light metal, which in the z. B. by means of an inductor tion coil heated mold is filled. After filling in the alumi nium melt and the subsequent controlled cooling gradually begins to solidify in the area of the cast body ends, while the aluminum melt in the middle of the cast body still remains fluid. This avoids the formation of cavities because the melt from the The middle of the casting body can flow into the solidification zones. You can also use the time-controlled cooling also reduces thermal stresses in the cast body, which results in a high ductility of the base node elements.
