Rear axle suspension system for motor vehicles, in which the wheel carriers on both sides are coupled to the body of the vehicle by at least one longitudinal link (9, 10), one transverse link (12) and a further transverse link (15, 16). In order to ensure that the axle kinematics distinguish between spring compression in the same direction and spring compression in opposite directions and a side force steering effect occurs, the transverse link (12) is a single connecting link which is connected to the two wheel carriers (3, 4) via first joints (5, 6) and connects both wheel carriers (3, 4), and the center of which (19) is guided, with respect to the body of the vehicle, in the longitudinal center plane of the vehicle, by a straight-guide (20 to 24). The straight-guide (20 to 24) is a Watt linkage (23, 24, 20).

The invention claimed is: 1. A rear axle suspension system for motor vehicles in which wheel carriers on both sides are coupled to a body of the vehicle in the transverse direction by means of at least one longitudinal link, one transverse link and a further guiding means, characterized in that the transverse link is a single connecting link which is connected to the two wheel carriers via first joints and connects the two wheel carriers and a center of which is guided, with respect to the body of the vehicle, essentially in a longitudinal center plane of the vehicle, by means of a straight-guiding means, the straight-guiding means being a linkage which is composed of two rockers which are transverse with respect to the direction of travel and one coupling which is arranged in an essentially vertical plane. 2. The rear axle suspension system as claimed in claim 1, characterized in that the further guiding means in the transverse direction is a telescopic guiding means between the wheel carrier and the body of the vehicle and the longitudinal links are connected to the wheel carrier by means of a joint. 3. A rear axle suspension system for motor vehicles in which wheel carriers on both sides are coupled to a body of the vehicle in the transverse direction by means of at least one longitudinal link, one transverse link and a further guiding means, characterized in that the transverse link is a single connecting link which is connected to the two wheel carriers via first joints and connects the two wheel carriers and a center of which is guided, with respect to the body of the vehicle, essentially in a longitudinal center plane of the vehicle, by means of a straight-guiding means, the straight-guiding means is a linkage which is composed of two rockers and one coupling which are arranged in an essentially vertical plane which is transverse with respect to the direction of travel, the first joints to which the connecting link is coupled being arranged on the wheel carriers at the bottom, and the connecting link is connected to the coupling of the linkage in the center plane of the connecting line of the two first joints by means of a second joint which is arranged above the connecting line. 4. The rear axle suspension system as claimed in claim 3, characterized in that the further guiding means in the transverse direction is a telescopic guiding means between the wheel carrier and the body of the vehicle and the longitudinal links are connected to the wheel carrier by means of a joint. 5. A rear axle suspension system for motor vehicles in which the wheel carriers on both sides are coupled to a body of the vehicle in the transverse direction by means of at least one longitudinal link, one transverse link and a further guiding means, characterized in that the transverse link is a single connecting link which is connected to the two wheel carriers via first joints and connects the two wheel carriers and a center of which is guided, with respect to the body of the vehicle, essentially in a longitudinal center plane of the vehicle, by means of a straight-guiding means, the longitudinal link being permanently connected to the wheel carrier, the further guiding means in the transverse direction is a transverse link which acts on the wheel carrier at the top by means of a further joint, and the first joint is arranged below and behind a third link in the direction of travel. 6. The rear axle suspension system as claimed in claim 5, characterized in that the further guiding means in the transverse direction is a telescopic guiding means between the wheel carrier and the body of the vehicle and the longitudinal links are connected to the wheel carrier by means of a joint. 7. The rear axle suspension system as claimed in claim 6, characterized in that, the straight-guiding means being a linkage which is composed of two rockers which are transverse with respect to the direction of travel and one coupling which is arranged in an essentially vertical plane. 8.
