The first anti-roll device and the second anti-roll device are articulated to the coupling device at first and second articulation points, respectively. The coupling device is configured such that, caused by a counterforce-free first displacement of the first anti-roll device via the first and second articulation points, an opposing second displacement is introduced into the second anti-roll device. ## Claims ### Claim 1 A vehicle comprising: a vehicle longitudinal axis, at least one first vehicle component, at least one first spring device on at least one first wheel unit, and at least one second spring device on at least one second wheel unit, which is set apart from the first wheel unit in the direction of the vehicle longitudinal axis, and at least one first anti-roll device and a second anti-roll device, which are coupled to one another via a coupling device, the at least one first anti-roll device and the second anti-roll device are each connected to the first vehicle component and each counteract rolling motions of the first vehicle component about a roll axis parallel to the vehicle longitudinal axis, wherein the first anti-roll device is articulated to the coupling device at a first articulation point, the second anti-roll device is articulated to the coupling device at a second articulation point, and the coupling device is configured in such a way that, caused by a counterforce-free first displacement of the first anti-roll device via the first articulation point and the second articulation point, an opposing second displacement is introduced into the second anti-roll device. ### Claim 2 (depends on 1) The vehicle according to claim 1, wherein the first anti-roll device is articulated to the coupling device at a first articulation point, the second anti-roll device is articulated to the coupling device at a second articulation point, and the coupling device is configured in such a way that a counterforce-free first displacement of the first articulation point brings about an opposing second displacement of the second articulation point. ### Claim 3 (depends on 1) The vehicle according to claim 1, wherein the first displacement and the second displacement comprise substantially the same amount but in differing direction. ### Claim 4 (depends on 1) The vehicle according to claim 1, wherein the first articulation point is a bearing point of the first anti-roll device with respect to the first vehicle component, and the second articulation point is a bearing point of the second anti-roll device with respect to the first vehicle component. ### Claim 5 (depends on 1) The vehicle according to claim 1, wherein the coupling device connects parts of the first anti-roll device and the second anti-roll device that are located on the same side of the vehicle longitudinal axis. ### Claim 6 (depends on 1) The vehicle according to claim 1, wherein the coupling device connects components of the first anti-roll device and the second anti-roll device that have the same function or position within the respective anti-roll device. ### Claim 7 (depends on 1) The vehicle according to claim 1, wherein the coupling device comprises at least one first lever arm which is articulated to the first vehicle component so as to be able to pivot about a first pivot point, the first pivot point being arranged in a kinematic chain between the first anti-roll device and the second anti-roll device. ### Claim 8 (depends on 7) The vehicle according to claim 7, wherein the first lever arm comprises a free first end and a free second end, the first end being connected directly to the first anti-roll device, and the second end being connected to the second anti-roll device. ### Claim 9 (depends on 7) The vehicle according to claim 7, wherein the coupling device comprises at least one second lever arm which is articulated to the first vehicle component so as to be able to pivot about a second pivot point, the second pivot point being arranged in the kinematic chain between the first anti-roll device and the second anti-roll device, and the second lever arm being connected to the first lever arm via at least one coupling element. ### Claim 10 (depends on 1) The vehicle according to claim 1, wherein at least one of the anti-roll devices comprises a torsion element connected to the first vehicle component. ### Claim 11 (depends on 1) The vehicle according to claim 1, wherein the first vehicle component is an undercarriage frame, the first anti-roll device is connected to the first wheel unit, and the second anti-roll device is connected to the second wheel unit. ### Claim 12 (depends on 1) The vehicle according to claim 1, wherein the first vehicle component is a body, the first anti-roll device is connected to the first wheel unit, and the second anti-roll device is connected to the second wheel unit. ### Claim 13 (depends on 1) The vehicle according to claim 1, wherein the first vehicle component is a first body having a first body end and a second body end; a second body, which is adjacent to the first body end, and a third body, which is adjacent to the second body end, are provided, the first anti-roll device is connected to the second body; and the second anti-roll device is connected to the third body. ### Claim 14 (depends on 13) The vehicle according to claim 13, wherein the first body is configured in the manner of a wheelless sedan, said first body being fastened to the second body and the third body. ### Claim 15 (depends on 1) The vehicle according to claim 1, wherein the coupling device comprises at least one first working cylinder, which is connected to the first anti-roll device, at least one second working cylinder, which is connected to the second anti-roll device, and at least one connecting line, which connects the first working cylinder and the second working cylinder, for a working medium. ### Claim 16 (depends on 1) The vehicle according to claim 1, wherein at least one of the wheel units comprises a set of wheels. ### Claim 17 (depends on 1) The vehicle according to claim 1, wherein the coupling device comprises a damping device. ### Claim 18 (depends on 1) The vehicle according to claim 1, wherein the coupling device comprises an adjusting device.
