Embodiment Construction

[0029] exist figure 1 The body structure of the front vehicle of the vehicle is shown in , and the scope shown is necessary for understanding the present invention. Accordingly, the body structure has two body side members 1 extending toward the rear in the vehicle longitudinal direction x, to which a subframe 10 is attached via a front fastening point 11 and a rear fastening point 12 ( via elastic supports not shown). The subframe 10 has two laterally opposite subframe longitudinal supports 14 in the vehicle longitudinal direction x, which are fastened at the front node elements 13 (eg cast nodes) by means of front fastenings. Point 11 is attached to the body rail 1 . The two front node elements 13 are connected to one another via the front subframe transverse carrier 9 .

[0030] The rear side member fastening point 12 of the subframe 10 is designed directly adjacent to the rear control arm bracket 52 on which the transverse control arm 53 is articulated in the assembled ...

Abstract

The invention relates to a two-track vehicle having a chassis suspension system, in particular having a front axle subframe (10) which is attached to lateral body longitudinal carriers (1), and having a drive assembly mounting component, in particular having a tunnel crossmember (30) which is spaced apart from the subframe (10) by a longitudinal offset (DELTA x) in a vehicle longitudinal direction (x) and bridges a body-side centre tunnel (6), wherein a drive assembly (7) is supported via bearing points (5) both on the subframe (10) and on the tunnel crossmember (30). According to the invention, an intermediate coupling element (20) is provided which connects the subframe (10) to the tunnel crossmember (30) in a force-transmitting manner while bridging the longitudinal offset (DELTA x).

Description

technical field [0001] The invention relates to a double-track vehicle according to the preamble of claim 1 . Background technique [0002] The body structure of a motor vehicle is arranged such that dynamic rigidity requirements (eg torsional rigidity about the longitudinal center axis of the vehicle when cornering) are met during normal driving operation. Furthermore, the body structure is arranged in such a way that in the event of a crash event, the impact forces can be introduced into the body structure with as little deformation as possible. [0003] DE 10 2006 013 550 A1 discloses a vehicle of this type which has a front axle subframe as the chassis suspension, which is attached to side rails on both sides. The vehicle also has a tunnel cross-carrier / tunnel cross member as a drive unit bearing part. The tunnel transverse carrier is spaced apart from the subframe by a longitudinal offset in the vehicle longitudinal direction and bridges the body-side central tunnel i...
