Embodiment Construction

[0030]In the different drawings, the same parts are always given the same reference numbers, which is why they are usually only described once.

[0031] Such as figure 1 The chassis arrangement shown is preferably located in the front region of the vehicle, not shown, wherein the front of the vehicle is located in the figure 1 on the right side of the . The X-direction extends in the longitudinal direction of the vehicle, while the Z-direction extends vertically through the vehicle. The chassis arrangement has a subframe 11 fastened to the vehicle component. This component is the longitudinal member 30 of the vehicle. The subframe 11 is connected to the longitudinal member 30 via at least one fastening point, not shown in detail. The area of ​​the fastening point is in the figure 1 The circle indicated by the dashed line and the reference numeral 20 in . The subframe 11 is located below this fastening point 20 . Preferably, a plurality of such fastening points are provi...

Abstract

A chassis device for a motor vehicle comprises a chassis comprising an auxiliary frame (10) connected to a part (30) of the chassis or a vehicle body via at least one fastening point (20). The fastening points (20) are configured to be released along the z axis by a predetermined force between the part (30) of the chassis or a vehicle body and the auxiliary frame (10). According to the invention,the front area of the auxiliary frame (10) is provided with at least one inclined slope (40) which can come in contact with a part moving toward the auxiliary frame (10) under the collision of the motor vehicle, so that a force is applied to the fastening points (20) between the auxiliary frame (10) and the part (30) of the chassis or the vehicle body along the z axis.

Description

technical field [0001] The invention relates to a chassis arrangement for a motor vehicle according to the preamble of claim 1, comprising a chassis with a subframe connected to the chassis or to a part of the bodywork by at least one fastening point , wherein the fastening point is configured such that it is released along the Z-axis under a predetermined force between the chassis or the part of the body and the subframe. The invention also relates to a motor vehicle having such a chassis arrangement. Background technique [0002] Motor vehicles generally include a chassis arrangement having at least one frame and an underbody supported by the frame. Furthermore, in vehicles with a self-supporting body, subframes and / or subframes are provided which support the various vehicle components. This includes in particular components of the drive train and wheel suspension units. Such subframes are fastened, for example, to the underbody or longitudinal members of the vehicle, w...
