Eine Wippe (13) des Wattgestänges (12) ist an der Kraftfahrzeugkarosserie (4) gelagert. Das Wattgestänge (12) vermeidet ein Übersteuern des Kraftfahrzeuges bei Kurvenfahrt. Da das Wattgestänge (12) einen Großteil der Radführungsaufgaben übernimmt, ist eine teilweise Entkoppelung der Radführungsaufgaben der Dämpfungsbuchsen möglich, was zu Freiheiten bezüglich der Kennlinienauslegung in Richtung deutlich höherem Fahrkomfort führt. A wheel suspension (3) for unguided wheels (2) on a motor vehicle body (4) of a motor vehicle has a torsion beam axle (6) with a Watt linkage (12). A rocker (13) of the Watt linkage (12) is mounted on the motor vehicle body (4). The Watt linkage (12) avoids oversteer of the motor vehicle when cornering. Since the Watt linkage (12) takes over a large part of the Radführungsaufgaben, a partial decoupling of the Radführungsaufgaben the damping bushings is possible, which leads to freedom in terms of the characteristic interpretation in the direction of significantly higher ride comfort.

Wheel suspension for motor vehicles, especially rear wheel suspension

The wheel suspension comprises a rigid axle beam, on either end of which a shock absorber or spring strut carrying a wheel carrier is supported. Between these parts a universal joint is inserted which is fixed on the axle beam so that it cannot rotate. The axle beam is pivoted on the vehicle body by means of longitudinal suspension links rigidly fixed to this. In this construction the wheel carriers only have two degrees of freedom lying in vertical planes perpendicular to one another so that, although capable of wobbling, they are supported on the axle beam in such a way that they cannot rotate about a vertical axis. The wheel carriers are thereby held on the axle beam with a fixed toe-in so that only those moments caused by wheel caster acting about the vertical axis act on the axle beam. Moments resulting from longitudinal and lateral guiding forces and acting about the other two axes of rotation of the universal joint are only supported as forces on the axle beam.

Rear axle for a vehicle particularly a motor vehicle

A rear axle for a vehicle, specifically a non-driven rear axle of a motor vehicle, is formed from two flexurally and torsionally rigid longitudinal guide arms 21, 22, on which the wheels 15 are rotatably mounted, and a flexurally rigid but torsionally resilient transverse beam 14 which interconnects the longitudinal guide arms and is connected to the respective longitudinal guide arms in an angularly rigid manner by welding. The transverse beam has an open cross-section which has its plane of symmetry disposed horizontally. In its central region between the longitudinal guide arms the transverse beam has a V-shaped cross-section, whereas in the region of its connections to the respective longitudinal guide arms the transverse beam has a U-shaped cross- section. The two cross-sectional shapes merge into each other gradually. The beam is thereby relatively free from deformation under torsional forces whilst its U-shaped ends are more adapted for connections to the guide arms. ...

Suspension and axle assembly

A suspension and axle assembly is provided having two identical stampings, each of which forms a portion of an axle and a portion of first and second suspension control arms that extend from the axle. The two stampings are coupled to one another along a continuous weld path. The assembly eliminates the connection points between the axle and control arms. The assembly also defines a pair of bores in which springs may be disposed at varying heights to lower the vehicle floor and reduce loads on the control arms, bushings, and other joints.

Roll center height variator

A roll center variator is described, generally including a first transverse locating device, a second transverse locating device, an adjustable spacing mechanism, and first and second simple links attached to the spacing mechanism and a vehicle axle. Each of the transverse locating devices has two ends attached to opposing sides of a vehicle frame. The spacing mechanism is attached at a first point to the first locating device and at a second point to the second locating device. The first and second locating devices are comprised of a Watt's linkage, Panhard rod, or other transverse locating device. The variator includes a screw-threaded rod engaged with the spacing mechanism, wherein rotation of the rod in one direction increases a distance between a first point and a second point of the spacing mechanism and rotation in the opposite direction decreases the distance between the same two points.

Simplified self adjusting suspension - uses transverse leaf spring with height servo to middle of spring

The self adjusting suspension has a transverse leaf spring (5) braced on the chassis at two points (7, 8) and acting as track rods at the outside ends, to set the wheels. The middle of the spring is linked to a height control servo (4). This provides a simple regulating control which allows each wheel a measure of independent suspension. The leaf spring does not need to reach to the wheels and can be linked to the wheels by short tracked rods. The system requires only one servo on one axle. The servo unit operates hydropneumatically to provide a balance with the front suspension.
