Abstract

With the using up of the stroke of the coupling (10), the failure of a wear element (11), and the receding of the coupling into the coupling sleeve, load is directed through two deformation elements (1) side-mounted on the underframe (4). The deformation elements are attached to the underframe by a mounting plate (18). The enclosed casing (14) is built onto the underframe and has only one opening (15) for the coupling.

EXAMPLES

According to FIG. 1 to 3, the cores 3 can be covered by various known jacket shapes. The cross-sections of the cores 3 may also be of different design, in a known manner (FIGS. 4 to 6). The housing 2 may consist of various parts which are joined in a known manner. In the arrangement according to FIG. 7, the stroke of the clutch 10 is to be exhausted, the tear-off elements 11 and the clutch 11 are deflected back into the clutch.

- 4 shafts 12 carrying the load through two deformation elements 1, laterally arranged on the chassis 4 in the bumper position. The bogie 4 is offset with respect to the coupling plane by the stroke of the clutch 10 and the length of the deformation elements 1. At the front of these deformation elements 1 are profile plates 13 in order to avoid vertical relative displacements of the vehicles during the collision.

The whole device is located behind the cover 14, which has only the opening 15 for the coupling 10. The deformation elements 1 of FIG. 8 to 10 consist respectively of edged (provided edges) U-shaped sheets which are welded to the casing 2 in the form of a hollow box by means of an intermediate sheet metal strip 7. At the same time, the sheet metal 7 improves the deformation work E, grade A.E. utilization and ability to carry vertical loads. The front side is closed by a welded plate 16 having holes 17 for attaching the profile plate 13. At the rear end, the housing 2 is provided with a mounting plate 18 for attachment to the chassis 4.

Only the degree of A.E. For this purpose, the trapezoidal part of the metal sheet surface is replaced from the outside by a welded sheet having about half the thickness of the sheet metal of the jacket. 2, compared to a rectangular or square actuator, a more uniform compression curve. The compartments 8 welded transversely to the load direction promote uniform folding. Upon impact, the casing 2 deforms over its entire cross-section in the rhombic ripple mode typical of hollow cabinets of these dimensions. To improve grade A.E. Within the housing 2, there is a core 3 made of polycarbonate tubular honeycomb blocks. This has a substantially more favorable purchase price, high aging resistance and corrosion resistance over the aluminum hexagonal honeycomb structures used. The EA parameters are comparable. The height of the individual blocks corresponds approximately to the length of the folding wave (depth of the warehouse). The interlayers 9 as pressure plates of hardened fabric prevent unwanted failure in the impact area of the blocks.

The degree of utilization (A.E.) of the deformation element I is about 80%, the maximum degree of compression is about 70%.

It is conceivable and within the meaning of the invention that the deformation element is also used in areas other than the chassis attachment described above.
