Problems solved by technology

The channel frame and the longitudinal central channel are firmly and unshakably connected to each other by welding, although the fastening device known from DE 19728 557 B4 can compensate for manufacturing tolerances, but the assembly of the cross member to the body becomes rather laborious

Embodiment Construction

[0017] FIG. 1 shows a front structure 1 of a motor vehicle, not shown in other parts, which forms the front end of the passenger compartment. The front vehicle structure 1 is part of the vehicle body (not shown), on which a cross member 2 , here the driver's cab cross member 2 , is arranged, which usually serves as a support for an instrument panel, also not shown . The longitudinal ends 3 and 3 of the cross member 2 are firmly connected to the A-pillar of the vehicle, not shown, so that the cross member 2 increases the stiffness of the vehicle in the transverse direction. The driver's cross member 2 is supported in its central part 4 by means of a bracket 5 on the longitudinal central tunnel 6 of the motor vehicle, so that unintentional deformation of the cross member 2 , for example caused by the load of the instrument panel, can be avoided. In this case, the longitudinal central channel 6 generally serves as a channel for a not shown vehicle drive shaft, which extends, for...

Abstract

The invention relates to a crossbeam (2) in an automobile, especially a crossbeam (2) of a driver's cab, the longitudinal end of the crossbeam (2) is connected with the A-pillar of the front vehicle structure (1) of the automobile, and the crossbeam (2) Supported at its center (4) on the longitudinal center tunnel (6) of the vehicle by means of a bracket (5), wherein the bracket (5) has two downward supports (7, 7') and a connecting beam (8), said connecting beam (8) connects the lower ends of said two supports (7, 7'), the invention proposes that said connecting beam (8) can be passed through at least one fixing device (9 ) is fixed on the longitudinal central channel (6), and the fixing device (9) enables the connecting beam (8) to be adjustable on the longitudinal central channel (6) of the vehicle. This enables a stress-free and simple assembly of the cross member (2).

Description

technical field [0001] The invention relates to a cross member in a motor vehicle, in particular a cross member of a driver's cab, according to the preamble of claim 1 . Background technique [0002] DE 197 28 557 B4 discloses a fastening device for a cross member in a motor vehicle, wherein the cross member is connected to the body, in particular to the A-pillar, via clamping elements. The crossbeam is supported at its center on the longitudinal center tunnel of the vehicle by a bracket, wherein the bracket has two downward-facing supports and a connecting beam that connects the lower ends of the two supports. connect them. In this case, the connecting beam is designed as a tunnel frame and is welded to the longitudinal central tunnel of the vehicle. The channel frame and the longitudinal central channel are welded firmly and unshakably to each other, although the fastening device known from DE 19728 557 B4 can compensate for manufacturing tolerances, but the mounting of ...
