- the third Lasteinleit segment 7c comes flat on the core profile 6 to the plant.
- the Lasteinleit- elements 7, 8 are pressed axially against the core profile 6 and positively connected to each other.
- the axle strut 1 has a lateral offset.
- the first bearing portion 3a of the axle strut 1 is arranged in a first plane 17a, which is spaced from a second plane 17b, in which the second bearing portion 3b of the axle strut 1 is arranged. Consequently, the shaft 2 is arranged obliquely between the two bearing areas 3a, 3b.
- the axle strut 1 thus has two buckling points 18a, 18b.
- an axle strut 1 according to the invention with two bearings 19a, 19b is shown.
- the respective bearing 19a, 19b is arranged in the respective bore 13a, 13b of the respective load-introducing element 7, 8.
- the respective bore 13a, 13b is formed obliquely in the respective load-introducing element 7, 8. That is, the center axes 14a, 14b of the bores 13a, 13b are arranged so as to have a zero angle to a respective axis 15 which is perpendicular to the longitudinal axis 5 of the axle strut 1. Due to the oblique bores 13a, 13b, the two bearings 19a, 19b are also introduced obliquely in the axle strut 1.
- the axle strut 1 has a lateral offset. This means that the axle strut 1 is inclined in itself so that the first storage area 3a is arranged in a different horizontal plane than the second storage area 3b.
- the longitudinal axis 5 of the axle strut 1 forms an angle to a hoisting angle. has a horizontal axis 20. This horizontal axis 20 is perpendicular to the central axes 14a, 14b.
- FIG. 5 shows a schematic representation of the core profile 6 of the axle strut 1 according to the exemplary embodiments according to FIGS. 1 and 2d. Shown is the core profile 6, which is formed from a fiberglass. In Fig. 5 it can be clearly seen that the core profile 6 has a double-H-shaped cross-section. This is advantageous because a collapse of the core profile 6 under high pressure, which prevails, for example, during curing of the axle strut in an autoclave, is prevented. The core profile 6 can therefore withstand high external pressures.
- a transverse winding or transverse windings can be provided either around the bearing areas, or both about the bearing areas and about the shaft of the axle strut to support the support winding in the load application area when tensile forces occur and to protect the axle strut from contamination.
- the transverse winding or the transverse windings are formed for example of fiberglass.
- the shaft length of the axle strands is variable, that is, depending on how long the core profile is, the axle strut is made longer or shorter.
- the angle that the central axes of the bores in the Lasteinleit elements have to a vertical axis is variable. Depending on the vehicle type, this angle can be shaped differently, so that a different lateral offset can be achieved.

Abstract
L'invention concerne une barre de réaction (1) pour un véhicule, comprenant un arbre (2) ainsi qu'une première et une deuxième zone d'entreposage (3a, 3b), la barre de réaction (1) comprenant un enroulement porteur (4), un profilé de noyau (6) ainsi qu'un premier et un deuxième élément d'introduction de charge (7, 8), l'enroulement porteur (4) et le profilé de noyau (6) étant constitués d'un matériau composite de fibres et de plastique, et le premier élément d'introduction de charge (7) étant agencé au niveau de la première zone d'entreposage (3a) et le deuxième élément d'introduction de charge (8) étant agencé au niveau de la deuxième zone d'entreposage (3b), le profilé de noyau (6) étant agencé spatialement entre les deux éléments d'introductions de charge (7, 8). Selon l'invention, chaque élément d'introduction de charge (7, 8) est constitué d'au moins un premier et un deuxième segment (7a, 7b, 8a, 8b) d'introduction de charge, chaque segment (7a, 7b, 8a, 8b) d'introduction de charge comportant au moins partiellement une enveloppe (9a, 9b, 10a, 10b) respective en matériau composite de fibres et de plastique, l'enroulement porteur (4) venant en outre en appui au moins partiellement contre l'enveloppe (9a, 9b, 10a, 10b) respective de chaque segment (7a, 7b, 8a, 8b) d'introduction de charge, et l'enroulement porteur (4) entourant au moins partiellement les segments (7a, 7b, 8a, 8b) d'introduction de charge de chaque élément d'introduction de charge (7, 8) et le profilé de noyau (6) et les reliant ensemble le long d'un axe longitudinal (5) de la barre de réaction (1). L'invention concerne en outre un procédé de fabrication d'une barre de réaction (1) selon l'invention.
