Embodiment Construction

[0027] figure 1 A schematic plan view of the front end 1 of a motor vehicle is shown, wherein body and engine components are omitted in this plan view, and only the outline of the cooler structure 23 and components of the frontal crash structure surrounding it can be seen. In this case, the crash beam structure 8 forms a slightly curved arc extending from one end region 11 to the other end region 12 . This slightly arched arc makes it possible to transmit, for example, crash forces acting on the center of the reinforcement plate 14 via the stiffer crash beam structure 8 to the crash boxes 4 and 5 . The crash boxes 4 and 5 each consist of a first outer leg 26 and a second inner leg 27 and each have an outer flared end 28 and an inner flared end 29 in the direction of the crash beam structure 8 . Furthermore, the V-shaped crash boxes 4 and 5 form the rear ends 34 and 35 of their legs, which respectively jointly transition into the side members 2 and 3 of the vehicle. For thi...

Abstract

A motor vehicle front structure (1) is provided with at least one front frame (31) having two side members (2, 3) and an impact cross-member structure (8). Two crash boxes (4, 5) are fixed between the respective front end (6, 7) of the side members (2, 3) and the impact cross-member structure (8). Each of the crash boxes (4, 5) comprises a first and a second leg (26, 27) which are jointly fixed to the front end (6, 7) of each side member (2, 3). The first and second legs (26, 27) formed in a V merge shape with ends (28, 29) spread from each other in the direction of the impact cross-member structure (8). The spread ends (28, 29) are fixed on end regions (11, 12) of the impact cross member structure (8). Between the legs (26, 27) a connecting structure (40) with a honeycomb construction (41) is arranged.

Description

technical field [0001] The invention relates to a front end of a motor vehicle body having at least one front frame with two longitudinal beams and a crash beam structure. Two crash boxes are fastened between the respective front ends of the side members and the crash beam structure. Background technique [0002] Use this type of crash box in your car to increase safety. Furthermore, damage to the vehicle's body structure in accidents at lower speeds can be reduced through the use of such crash boxes. For this purpose, the crash box is designed as a deformation body which is installed in the vehicle in such a way that it partially absorbs the resulting crash energy by its deformation when the vehicle hits an obstacle. As a result, the crash box reduces the transmission of crash energy to the body structure, in particular the two vehicle side members, and thus can reduce or completely prevent damage to the body structure. [0003] Such a vehicle front end with a crash box ...
