Patent ID: 7891683

Claim:
A torsion-beam rear axle of a vehicle having a vehicle body, a longitudinal axis, a transverse axis, a first wheel carrier, a second wheel carrier, a first wheel and a second wheel, comprising: a first rigid trailing arm having a first end and a second end, the first end mounted so as to be capable of swiveling on the vehicle body and the second end attached to the first wheel carrier for the rotatable mounting of the first wheel about a first center axis of the first wheel; a second rigid trailing arm having a third end and a fourth end, the third end mounted so as to be capable of swiveling on the vehicle body and the fourth end attached to the second wheel carrier for the rotatable mounting of the second about a second center axis of the second wheel; a torsionally soft cross-tie connecting the first rigid trailing arm and the second rigid trailing arm; and at least three elastic wheel carrier bearings at least coupling one of the first wheel carrier to the first rigid trailing arm and the second wheel carrier to the second rigid trailing arm, wherein at least two bearings of the at least three elastic wheel carrier bearings are located behind at least one of the first center axis and the second center axis and at least one bearing of the at least three elastic wheel carrier bearings is located in front at least one of the first center axis and the second center axis in such a manner that through the at least two bearings, a swivel axis is defined for swiveling of at least one of the first wheel carrier relative to the first rigid trailing arm and the second wheel carrier relative to the second rigid trailing arm; wherein the at least two elastic wheel bearings comprises a first elastic damping bushing and a second elastic damping bushing, and wherein the at least one elastic wheel bearing comprises a third elastic damping bushing; wherein the first elastic damping bushing and the second elastic damping bushing each have an axis oriented substantially parallel to the longitudinal axis of the vehicle; wherein the third elastic damping bushing has an axis oriented substantially parallel to the transverse axis of the vehicle; and wherein the first elastic damping bushing and the second elastic damping bushing are arranged along an axis that is substantially orthogonal to both the transverse axis and the longitudinal axis of the vehicle.
