Definitions
- the present invention relates to a bumper cross member for connection to a body of a motor vehicle.
- a bumper cross member for a motor vehicle is known, for example, from DE 10 2010 054 638 A1.
- the bumper cross member consists of two separate hollow sections, which bear against each other on a longitudinal wall and are interconnected.
- the two hollow sections extend in the vehicle transverse direction and are connected to each other by means of welded joints.
- the two hollow profiles are surrounded by a U-shaped reinforcement component from the back.
- Bumper crossmember is attached via crash boxes on side members of the vehicle body.
- the bumper cross member according to the invention is for connection to a
- the bumper cross member has a hollow profile base carrier which is reinforced in the direction of travel on the front au Shen with a front U-profile carrier element.
- a non-free leg of the front U-Profillylements is spaced from a front side of the hollow profile base carrier formed.
- Hollow-profile base support constitutes an additional deformation path according to the degree of spacing before, in the collision with, for example, a pile, a tree or the like, i. a rigid and narrow obstacle, the collision force concentrated at the point of impact as a bending moment on the
- Bumper cross member in particular the hollow profile base acts.
- premature failure of the bumper cross member may possibly be prevented by tearing of the hollow profile base support at a relatively low total weight of the bumper cross member.
- Bumper crossmember free legs of the front U-profile support member are attached to an upper side or a lower side of the hollow profile base support.
- the upper free leg of the front U-profile carrier element is attached to the upper side of the hollow profile base carrier and is the lower free leg of the front U-profile carrier element at the bottom of
- the hollow profile base is a long profile with a closed hollow profile.
- the closed hollow profile is particularly preferably seamlessly designed to increase bending stiffness with the lowest possible weight.
- Bumper cross member is the non-free leg of the front U-profile support member at a vehicle transverse direction middle region of the bumper cross member, especially in the middle relative to the vehicle transverse direction, by 10 to 50 mm, preferably 15 to 25 mm, for example. About 18 mm, from the front the hollow profile base carrier spaced. The resulting large length of the total cross-section in the vehicle longitudinal direction increases the resistance to bending deformation.
- the unfree leg can be spaced substantially constant over its entire length from the hollow profile base support.
- the distance varies in the vehicle transverse direction and tends to almost zero in a lateral areas of the front U-profile carrier element. Since the bending stress of the bumper cross member is the highest in a collision at its central region, the spacing of the front U-profile carrier element and the bending resistance torque thus present at this position is most effective and therefore more necessary than at lateral areas of the bumper
- the bumper cross member via a left
- Body connection portion and a right body connection portion connectable to the body of the motor vehicle.
- Bumper cross member preferably directly or indirectly connected to a left side member and a right side member of the body of the motor vehicle. Indirect means that the bumper cross member on additional deformation elements, which are also called crash boxes, with the
- the front U-shaped carrier element extends at least from the left-hand body attachment section to the right-hand body attachment section of the bumper cross member.
- the front U-shaped support member is disposed substantially in the region between the left and right body joint portions.
- Bumper cross member which in turn through the centrally arranged front U-profile support member and the distance of the non-free leg of the front U- Profile carrier element is supported weight-optimized to the central portion of the hollow profile base support.
- the hollow profile base support on a chamber with a closed cross section, which extends in the vehicle transverse direction.
- the two or more chambers may preferably be arranged one above the other.
- Hollow profile basic carrier or the bumper cross member increased at low weight.
- the hollow profile base can consist of a single tube with a substantially rectangular or polygonal cross-section.
- the hollow profile base can also consist of two or more tubes.
- the tubes can, for example, together in the direction of travel at the front or in the direction of travel at the rear or in the direction of travel at the front and in the direction of travel behind each other materially, for example by welding.
- a cohesive connection of the plurality of separately produced tubes only at their front side is preferred because the front side of the hollow profile base carrier is least strained in the frontal collision (in particular in comparison to the back of the
- the hollow profile base can extend over an entire length of the bumper cross member.
- the hollow profile base carrier can also extend only between the two body connection sections of the bumper cross member.
- the hollow profile base support element or the hollow profile base support elements can be produced by hydroforming or by extrusion. This makes it easily possible a seamless hollow profile base
- the cross section over a length of the hollow cross member cross member may be made suitably variable.
- the hollow profile carrier at its central region has a in
- a rear U-profile carrier element can be fastened to the hollow profile base carrier.
- a non-free leg of the rear U-profile carrier element may be arranged opposite a rear side of the hollow profile base carrier.
- free legs of the rear U-profile carrier element may be fastened to an upper side or an underside of the hollow profile base carrier.
- the free legs of the front U-profile carrier element and the free legs of the rear U-profile carrier element can be designed such that they abut each other and can be secured together by a welded joint.
- the non-free leg of the rear U-profile carrier element is preferably formed adjacent to the rear side of the hollow profile base carrier. Adjacent means that essentially no gap is formed between the rear U-profile carrier element and the rear side of the hollow profile base carrier. Furthermore, the free legs of the rear U-profile carrier element may be formed adjacent to the top or the bottom of the hollow profile base carrier.
- groove-shaped depressions which can also be called beads, can be introduced in the vehicle longitudinal direction on an upper side and / or an underside of the hollow profile base carrier.
- the depth of the channel-shaped depression can be carried out decreasing in the vehicle longitudinal direction.
- a Beulsteiftechnik the bumper cross member may be further increased in the vehicle longitudinal direction.
- Stoßffiterque or the hollow profile base support the channel-shaped Recesses of the deformation and thus complicate premature failure of the bumper cross member by bumps. A flexural rigidity of the beam is thus retained during a collision-induced deformation.
- the hollow profile base support and / or the front U-profile support element may be formed from a high-strength steel.
