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 ...
