A liquid seal bushing includes an outer member, an inner member, and an elastic body which connects the outer member and the inner member to each other. The bushing includes two liquid chambers, a connection path which connects the two liquid chambers and extends in one direction, a first communication path which allows communication between one end portion of both end portions of the connection path, the one end portion being located on a side of one liquid chamber of the two liquid chambers, and the other liquid chamber, a second communication path which allows communication between the other end portion of the both end portions of the connection path, and a linear motor provided inside the outer member including a movable element in the connection path and movable in the one direction to closes both openings of the first communication path and the second communication path.

A wheel suspension for a vehicle axle of a two-track vehicle, having a wheel carrier carrying a vehicle wheel, which is able to be articulated to a vehicle body via a multi-link assembly, which multi-link assembly has a trapezoidal link in the form of a four-point link with two connection points on the body side and two connection points on the wheel carrier side. The trapezoidal link connection points on the wheel carrier side are designed with a higher elastic longitudinal compliance, that is, softer, than the trapezoidal link connection points on the body side.

Provided are a suspension bushing and a suspension device with which maneuvering stability can be improved without adversely affecting ride quality. Protrusions are formed on the outer circumferential surface of an inner tube, and slits are formed on the inner circumferential surface of an outer tube. The protrusions are arranged in the slits and have a tapered shape in which their width in a direction parallel to an axial line decreases as the distance from the axial line increases. The slits have a shape such that a gap in the direction parallel to the axial line decreases as the distance from the axial line increases.

Provided are a suspension bush and a suspension device that are able to achieve both steering operability and stability of a vehicle at the time of turning. A projection portion is formed on the outer circumference of an inner cylinder. A guide is formed on the inner circumference of an outer cylinder. In the guide, a slit is formed along an extending direction that includes: a component, in a parallel direction, which runs parallel with an axial line; and a component in a circumferential direction around the axial line. The projection portion is disposed in the slit, and a threaded mechanism is formed by the projection portion and the slit.

A vehicle suspension system having a twist beam axle including a crossbeam and two trailing arms connected thereto. The rear ends of each trailing arm, in the motor vehicle longitudinal direction, having with a wheel mount for fastening a motor vehicle wheel. The front ends of each trailing arm connected via a bearing to the motor vehicle body. Each bearing associated with a MEMS designed as an actuator wherein movements of the bearings and therefore the twist beam axle about the vertical motor vehicle axis can be caused or unfavorable movements of the twist beam axle can be counteracted.

A suspension assembly for a vehicle suspension system may include a lower control arm, an upper control arm, a damper, and a drop link. The lower control arm may be operably coupled to a chassis of a vehicle via a first bushing assembly and a second bushing assembly. The first and second bushing assemblies may each pivot about an axis substantially parallel to a longitudinal centerline of the vehicle. The upper control arm may be operably coupled to the chassis. The damper may be operably coupled to the lower control arm to dampen pivoting motion of the upper and lower control arms relative to the chassis. The drop link may operably couple the lower control arm and an anti-roll bar that includes a disconnect assembly to translate a roll motion into a force exerted on the lower control arm in a direction substantially parallel to the axis.

A variable stiffness automotive suspension bushing (1) comprises a shaft or rod connected to a wheel member, an inner cylinder fixedly connected to the shaft or rod, and an outer cylinder fixedly connected to a chassis member. A magnetorheological (MR) elastomer, having iron particles embedded therein, is interposed between the inner and outer cylinders, and a coil is disposed about the inner cylinder. When the coil is energized by electrical current provided from a steering control module, a variable magnetic field is generated so as to influence the magnetorheological (MR) elastomer whereby variable stiffness values of the elastomer are obtained to provide the bushing (1) with variable stiffness characteristics in order to, in turn, provide the vehicle with optimal wheel deflection.

A vehicle includes a suspension system for providing configurable stiffness and damping. The system includes a plurality of hydraulic cylinders, each corresponding to a respective wheel of the vehicle, and one or more valve assemblies for controlling hydraulic fluid in the plurality of hydraulic cylinders to achieve a plurality of suspension modes affecting bounce, pitch, roll, and warp. The system also includes a plurality of accumulators acting as spring elements for storing and releasing the hydraulic fluid as the plurality of hydraulic cylinders compress and rebound. The system includes control circuitry for controlling the valve assemblies to achieve one or more suspension modes defining bounce, pitch, roll, and warp stiffnesses. By generating control signals for the valve assemblies, various interconnections or fluid paths can be achieved, corresponding to the suspension modes. The hydraulic cylinders are double acting, with rebound and compression volumes, and may be coupled to damping valves.
