US 2022/0219503 A1 · REAR AXLE FOR A TWO-TRACK VEHICLE AND TWO-TRACK VEHICLE WITH A REAR AXLE

Abstract

A rear axle for a two-track vehicle includes a first trailing arm, a first wheel carrier with a first wheel center and a first longitudinal strut, which form a first coupling mechanism that is effective in a longitudinal and/or a vertical direction of the vehicle. A second trailing arm and a second wheel carrier with a second wheel center and a second longitudinal strut form a second coupling mechanism that is effective in a longitudinal and/or a vertical direction of the vehicle, and a crossmember is firmly connected to the first trailing arm and to the second trailing arm and has a shear center. The first coupling mechanism has a first instantaneous center of rotation located on the front side and above the first wheel center, and the second coupling mechanism has a second instantaneous center of rotation located on the front side and above the second wheel center. A two-track vehicle having a chassis or an underbody includes such a rear axle arranged on the chassis or on the underbody.

A rear axle for a two-track vehicle, the rear axle comprising:

a first coupling mechanism that is effective in at least one of a longitudinal direction of the vehicle or a vertical direction of the vehicle, the first coupling mechanism comprising a first trailing arm, a first wheel carrier with a first wheel center, and a first longitudinal strut;
a second coupling mechanism that is effective in at least one of the longitudinal direction of the vehicle or the vertical direction of the vehicle, the second coupling mechanism comprising a second trailing arm, a second wheel carrier with a second wheel center, and a second longitudinal strut;
and
a crossmember firmly connected to the first trailing arm and to the second trailing arm, the crossmember having a shear center;
wherein the first coupling mechanism has a first instantaneous center of rotation located forward from and above the first wheel center, relative to the vehicle;
and
the second coupling mechanism has a second instantaneous center of rotation located on forward from and above the second wheel center, relative to the vehicle.
