A vehicular single wheel suspension of a double-track rear wheel being steerable by an actuator of a double-track vehicle has a wheel carrier guided by a longitudinal control arm and by two transverse control arms. The transverse control arms are connected to the wheel carrier by a bolt via a rubber bearing having a minimal degree of rotary freedom. The longitudinal control arm is mounted on the wheel carrier via one rubber bearing having a minimal degree of rotary freedom, such that the wheel carrier is swivelable relative to the longitudinal control arm about a substantially vertical swivel axis. The swivel axis is formed by the rubber bearing wherein the resulting degree of rotary freedom is bound by a tie rod element connected to the wheel carrier via an articulated joint. The tie rod element is movable in the transverse direction of the vehicle by an actuator adjuster element.

Vehicle independent wheel suspension for a slightly steerable rear wheel of a double-track vehicle

A front wheel suspension on a two-track vehicle having a wheel carrier or pivot bearing guided by an articulated suspension link is provided with an add-on part arranged such that during an impact of the vehicle on an obstacle which penetrates into the space bridged by the suspension link between a wheel and an axle support or vehicle body, the add-on part forms a lever arm on an articulated connection of the suspension link to separate the link by opening or destroying the connection. Separation of the articulated connection allows the vehicle wheel to be displaced laterally away from the vehicle interior. The add-on part may be fastened by a fastening screw of the articulation connection or be an extension of the screw. The add-on part may have a bead or a punch ring which has a destructive effect on the articulated connection during impact-caused displacement of the add-on part.

Front wheel suspension on a two-track vehicle

A countersteering vehicle rear axle induces a rotational motion of a wheel carrier about a virtual spread axis in the toe-in direction under the influence of a lateral force on the outside cornering wheel mounted on the wheel carrier. A support member exhibits a section, which extends essentially parallel to the plane of the wheel carrier, and a section, which is connected, when viewed in the direction of travel, to former section behind the wheel center point and extends essentially in the transverse direction of the vehicle. In a lateral projection, the support member is inclined in relation to the vertical direction in essentially the same way as the virtual spread axis. This support member is supported at least on the free ends of a sheet metal support plate, which in a lateral projection is approximately U-shaped and which in turn is mounted on the axle body.

Countersteering rear axle of a vehicle

In a vehicle wheel suspension, a first trailing arm is oriented in the longitudinal direction of the vehicle and a second trailing arm in the direction of an angle bisector between the longitudinal and transverse directions. The ends of the trailing arms determine a substantially horizontal instantaneous axis for the wheel carrier relative to the spring jounce and rebound motions of the vehicle chassis. The wheel carrier is slightly pivotable about a toe axis under the influence of braking forces. A support arm securely connects to the wheel carrier and extends over a defined distance substantially in parallel with and supported on the second trailing arm. The support is softer in the horizontal direction than in the vertical direction. A suitable design of the second trailing arm and/or the support arm allows a slight pivot motion of the wheel carrier about the toe axis.

Vehicle wheel suspension of the semi-trailer type

A countersteering rear vehicle axle, which under the effect of a lateral force upon the wheel that is outside during cornering and is fastened to a wheel carrier, causes a rotating movement of this wheel carrier about a virtual steering axle inclination in the toe-in direction. The wheel carrier is supported by supporting elements on an axle body extending essentially in the longitudinal direction of the vehicle. Above and below the wheel center, in each case, two torsionally soft but bend-resistant supporting elements are provided which are essentially equally inclined with respect to the vertical direction. An upper linkage supporting element is supported, on the one side, on the wheel carrier and, on the other side, on an upper torsion supporting element which is supported on the axle body. A lower linkage supporting element is supported on the wheel carrier, on the one side, and on a lower torsion supporting element, on the other side.
