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.
