Abstract

Two side pieces, each assigned to one longitudinal side of the vehicle, of rear axle supports for passenger vehicles are customarily connected to one another by two transverse tie bars arranged at a distance from one another, In a known type of vehicle, the rearward transverse tie bar, which is designed to be flexible, as seen in the direction of travel, is provided in front of a body cross-member which is directly adjacent to a spare wheel pan, near the rear crumple zone of the body at the floor. In the case of a crash, the spare wheel strikes the rearward transverse tie bar via the spare wheel pan. To increase this crumple zone in the body floor region, the rearward transverse tie bar is provided with lateral clearance between the body cross-member and the spare wheel pan. The body cross-member can thus be arranged at a correspondingly large distance from the spare wheel pan, and a corresponding free path for the spare wheel can be achieved. The profile of the rearward transverse tie bar, which is flexible in the longitudinal direction of the vehicle, will not form a stop unfavorably influencing the desired deformation in the rearward floor region.
