Abstract
In a bearing structure for a motor vehicle, in order to improve firmness, a plurality of reinforcing members are provided. The reinforcing members are composed of spoke elements, and the spoke elements are disposed a beam having the structure under the action of a tensile stress. Because the continuous tensile stress is applied to the beam, the spke elements are prevented from bending caused by a compression stress.
Description
Technical field
The present invention relates to the carrying structure of a kind of propons auxiliary frame being particularly useful for motor vehicles or subframe (Fahrschemel)。
Background technology
From the known a kind of carrying structure for vehicle of DE10351270A1, wherein this structure is firmly arranged among vertical tensile stress by stretching element and is designed to compressive load is pliable and tough。In addition from DE10059261A1, it is known that a kind of motor vehicle body, this motor vehicle body includes the connecting element being arranged in bottom section, this connecting element is made up of the stretching element of pretension, should realize promoting the moment of torsion natural frequency of automobile body by this stretching element。
Summary of the invention
General object of the present invention is to provide a kind of carrying structure for motor vehicles, for instance for the carrying structure of subframe or auxiliary frame, and this carrying structure is all optimized in its weight, intensity and robustness。
According to the present invention, this purpose carrying structure according to the present invention realizes。
The advantage mainly realized by the present invention is in that, carrying structure for motor vehicles (such as subframe or propons auxiliary frame) improves its robustness on the whole, this is achieved in the following manner according to the present invention: be provided with strenthening member between the longitudinal and cross beam spaced apart from each other of the frame element of carrying structure, and these strenthening members are made up of single spoke member, these single spoke member are loaded with tensile stress and are arranged between these frame elements in vertically and horizontally plane。Especially proposing in the improvement project of the present invention, these strenthening members are provided diagonally opposed at above and below the longitudinal and cross beam of carrying structure between angle point respectively, and intersect in a zone line。
According to this reason, constitutional detail achieves the principle of wheel-spoke；Because all of single spoke member is all load tensile stress and can be designed to extremely thin and light。The constitutional detail of vehicle comprises for all important accommodation portion necessary propons auxiliary frame and subframe and function point。
Propose further according to the present invention, this carrying structure substantially in box like ground by each side laterally overlap each other arrange longeron and be connected overlap each other setting front crossbeam and a rear crossbeam constitute, and in the free space between the beam that these are independent on these sides and on a front and rear side, it is fixedly provided in the single spoke member of tensile stress pretension in the corresponding angle point of carrying structure。
These single spoke member of pretension between the beam of this structure achieve lasting compression stress by the design in constitutional detail and layout in whole carrying structure。Therefore, alternate load (tension load such as replaced and compressive load) can convert to the load (such as more tensile stress/less tensile stress or more pressure/less pressure) of fluctuation effectively, and this is advantageous for for the fastness in useful life of this structure。By being in the single spoke member under lasting tensile stress, these single spoke member are not subject to compressive load, and this can not cause the bending in single spoke member。
Strenthening member according to the present invention is preferably made up of the single spoke member of the little pretension of diameter so that form large-area air passing space between these single spoke member and beams of this structure in supporting structure。
The single spoke member of the present invention is designed to very thin, and can expand the crossbeam of this structure and the circulation area of longeron significantly, without reducing the robustness of frame structure。
By the single spoke member that the pretension between the longitudinal and cross beam of this frame structure is arranged, form the rigid composite body of total unit。The robustness of system is significantly enhanced, because by defining the system firmer than the system being provided with casting pillar with the spoke element of this layout and structure and its function, the pillar further according to prior art is likely to buckle when compressive load at this。
Accompanying drawing explanation
Embodiments of the invention are shown in the drawings and described in。
Shown in figure:
Fig. 1 illustrates the supporting structure according to prior art, have have between the crossbeam of supporting structure fixing, execute stressed pillar；And
Fig. 2 illustrates the carrying structure according to the present invention, has the single spoke member with tensile stress pretension between the beam of this structure。
Detailed description of the invention
Carrying structure 1 for motor vehicles such as can be made up of propons auxiliary frame and subframe or the like body, and having the strenthening member 6,7 and 8,9 and 10,11 between frame element, this frame element is constituted (Fig. 2) by longeron 2,3 and 4,5。
These strenthening members are made up of so-called single spoke member 12, and these single spoke member load tensile stress in the mounted state constantly, and preferably in vertically and horizontally plane is arranged on longitudinal and cross beam 2,3 and 4,5, between 5a。
These strenthening members 6,7 and 8,9 and 10,11 be provided diagonally opposed at respectively the longitudinal and cross beam 2,3 and 4 being mutually in height spaced apart of carrying structure 1,5, above and below 5a between angle point E1 and E2, and intersect in a zone line B in horizontal or vertical plane。Substantially in box like, ground is equipped with respectively at the longeron 2,3 and the front crossbeam 4,5 being connected and rear crossbeam 5a that arrange of laterally overlapping each other for carrying structure 1, and they respectively constitute the frame element of the frame element in front, the frame element of lower section and side。
These beams 2,3 and 4,5, free space between 5a is provided with single spoke member 12, these single spoke member arrange or are tightly retained in advance in corresponding angle point E1 and the E1 of coincidence of beam。
These strenthening members 6,7 and 8,9 and 10,11 are especially made up of the single spoke member 12 of relative thin, and they are under lasting tensile stress and are so arranged between these beams of this structure 1 so that whole carrying structure 1 is all under compression stress。
At diameter or being kept as relative thin and thin single spoke member 12 by these in size, create large-area air passing space L between the beam of this structure 1, this air passing space ensure that the optimum ventilation of vehicle part。According to Fig. 1, these pillars are set to thicker, heavier according to prior art and can bend under compressive load。
For whole carrying structure 1, by that be maintained at side, angle and be arranged on tightly in advance respectively single spoke member in a plane 12 (crossbeam and longeron 2,3 and 4,5, between 5a), create rigid composite body, kept the rigid requirements driving operating change by this rigid composite body best。
