Definitions
- the invention relates to a side member for a body of a
- a motor vehicle having a tubular support member extending in the direction of travel and having a straight portion of the support member, a curved portion of the tubular support member and a reinforcing member of the arcuate portion of the tubular support member, the reinforcing member being disposed within the arcuate portion of the tubular support member is.
- Such longitudinal members are known for example from DE 102 31 807 Al.
- the reinforcing element is fixed angularly to verti cal legs of the tubular support member.
- the angle-shaped reinforcing element has additional side bars for attachment to the vertical legs.
- the carrier part is a complicated component to be manufactured.
- this design leads to a very high stiffening of the vertical leg of the support member. In a crash of the motor vehicle forces are, however, introduced mainly in a lower horizontal leg of the support member in the arc section. Therefore, the known longitudinal member in the crash of the motor vehicle in the bow area is very yielding.
- the invention is based on the problem, a longitudinal beam of the type mentioned above educate so that it has a particularly high load capacity in a crash of the motor vehicle in the bow area.
- the reinforcing element is arranged straight through at least a portion of the bow portion and between a lower horizontal leg to an upper horizontal leg of the tubular support member.
- the longitudinal beam according to the invention By this design are introduced in the crash of the motor vehicle in the longitudinal beam according to the invention directly from the lower horizontal leg in the upper horizontal leg.
- the reinforcing element therefore stabilizes the bow area critical for the stiffness of the longitudinal member.
- the longitudinal member according to the invention in the crash of the motor vehicle in the bow area on a particularly high load capacity. Thanks to the invention, the kinetic energy introduced during the crash into the side member is reduced near the region of the longitudinal member which points in the direction of travel of the motor vehicle. Furthermore, the longitudinal beam according to the invention thereby has a particularly low weight.
- a reliable introduction of force from the reinforcing element in the upper horizontal leg of the support member can be easily achieved according to another advantageous embodiment of the invention, when facing the direction of travel end of the reinforcing element rests against the upper horizontal leg of the support member or directly opposite the upper horizontal leg.
- the intended rigidity of the longitudinal member according to the invention can be adjusted easily if the end of the reinforcing element facing the direction of travel has a supporting part connected to adjacent regions of the upper horizontal leg on the opposite section of the upper horizontal leg.
- the stiffness can be adjusted by a suitable choice of material or material thickness and shape of the support part.
- a reliable introduction of force from the lower horizontal leg into the reinforcing element of the support member can be achieved according to another advantageous embodiment of the invention easily when the reinforcing member is directly connected to the highest point of the lower horizontal leg of the arc section.
- the reinforcing element has according to another advantageous embodiment of the invention, a high stability, when the reinforcing element is designed in cross-section U-shaped.
- the reinforcing element has a central web and when the central web is fixed to a arranged on the lower horizontal leg of the support member flange.
- the reinforcing element contributes, according to another advantageous embodiment of the invention, when the reinforcing member has two interconnected reinforcing members and when each of the reinforcing members has one of the side webs.
- an internal combustion engine of the motor vehicle is connected to the side member via an engine mount.
- the longitudinal member according to the invention has in the region of the connection of the internal combustion engine a particularly high stability, when the reinforcing element is directly connected to an engine mount.
- connection of the reinforcing element with the engine mount designed in accordance with another advantageous embodiment of the invention structurally particularly simple when the reinforcing element has an aligned with a bearing eye of the support member bearing flange.
- the reinforcing element is fork-shaped at one end and is guided with a first fork element up to the upper horizontal leg and with a second fork element up to the lower horizontal leg.
- FIG. 1 is a perspective view of a side rail according to the invention
- Fig. 2 is a sectional view through the invention
- Fig. 3 is an exploded view of the invention
- FIG. 1 shows a side member for a body of a motor vehicle with a tubular support part 1.
- a reinforcing element 2 is arranged in the tubular support part 1.
- the tubular support part 1 has a straight section 3 and an arc section 4, which is guided over a Radaus originallyung 5 of the vehicle body.
- a pointing in the intended direction of travel of the motor vehicle end of the support member 1 has a flange 6 for connecting a crash box.
- At this end of the longitudinal member usually an unillustrated cross member is attached, which connects two arranged on each side of the body side rail together.
- the longitudinal member also has a bearing eye 7 for an engine mounting of an internal combustion engine of the motor vehicle.
- the reinforcing element 2 shows, in a sectional illustration through the longitudinal member from FIG. 1 in the region of the curved section 4 along the line II - II, that the carrier part 1 is tubular and has two vertical legs 8, 9, an upper horizontal leg 10 and a lower horizontal leg 11 having.
- the reinforcing element 2 has two reinforcing parts 12, 13 connected to one another.
- the reinforcing parts 12, 13 each have a vertically extending side web 14, 15.
- the side webs 14, 15 are each attached to one of the vertical legs 8, 9 and connected to one another at a common bottom 16.
- the side bars 14, 15 and the common bottom 16 form a U-shape of the reinforcing element 2.
- the curved section 4 of the carrier part 1 is composed of two shell parts 17, 18, which on the upper and lower horizontal legs 10, 11 via flanges 19, 20 are interconnected. Furthermore, the reinforcing element 2 has a central web 21, which is fastened to the flange 20 arranged on the lower horizontal leg 11 of the carrier part 1.
- FIG. 3 shows, in an exploded view of the longitudinal carrier, that the curved section 4 and the straight section 3 of the carrier part 1 are connected to one another.
- One of the reinforcing parts 12 of the reinforcing element 2 is fork-shaped and is provided with a fork element 22 on the lower horizontal leg 11 and with the other fork element 23 on the upper horizontal
- the upper horizontal leg 10 has a supporting part 24 for supporting the forces introduced by the reinforcing element 2 into the carrier part 1.
- the reinforcing element 2 has a bearing flange 25 arranged in alignment with the bearing eye 7 of the carrier part 1. In the assembled state of the longitudinal carrier shown in FIG. 1, the reinforcing element 2 rests on the highest point of the lower horizontal leg 11 and extends horizontally to the upper horizontal leg 10 the carrier part 1.
