A vehicle with 3 or more wheels includes at least two wheels aligned on the same axis. The vehicle has an intermediate centerline plane between the wheels parallel to a direction of movement, including a mass suspended in relation to the wheels defining a passenger or containment compartment, and two suspension groups kinematically connecting the suspended mass to the two aligned wheels. An anti-roll stabilizer device has at least one compensation mass kinematically connected to the suspended mass via a guide and movable in relation thereto. The anti-roll stabilizer device has a drive of the compensation mass to distance or bring the compensation mass closer to the centerline plane on the side opposite the displacement of a barycenter of the suspended mass with respect to the same centerline plane, to oppose the displacement with respect to the centerline plane of the position of the barycenter of the suspended mass.

A suspension actuator includes an upper mount, a lower mount, a first actuator mechanism, and a second actuator mechanism. The upper mount is connectable to a sprung mass of a vehicle. The lower mount is connectable to an unsprung mass of the vehicle. The first actuator mechanism forms a first load path between the upper mount and the lower mount. The first actuator mechanism is one of an electromagnetic linear actuator mechanism or a ball screw actuator mechanism. The second actuator mechanism forms a second load path in parallel with the first load path between the upper mount and the lower mount. The second actuator mechanism is one of a mechanical linear actuator mechanism, an air spring actuator mechanism, or a hydraulic actuator mechanism.

A suspension system includes a hydraulic cylinder having a piston chamber in which a piston moves and a rod chamber in which a rod moves. The hydraulic cylinder operably moves between a retraction and an extension. The system also includes a throttle valve, a branching, and a hydraulic reservoir fluidly coupled to the hydraulic cylinder. A fluid flow from the piston chamber is divided at the branching into a first fluid flow portion and a second fluid flow portion. The first fluid flow portion flows to the rod chamber of the hydraulic cylinder, and the second fluid flow portion flows through the throttle valve to the hydraulic reservoir.

A vehicle cab suspension is provided with a body having a mounting member positioned at least partially within the body. One or more resilient members connect the body to the mounting member and are placed in a compressed condition between the body and the mounting member when the vehicle cab suspension is in an unloaded condition. The body may be formed of first and second body pieces, each of which may be provided with upper and/or lower projections to restrict movement of the resilient members during use.

A cabin suspension arrangement for a utility vehicle, having a plurality of trailing arms that extend in a longitudinal direction, by which a driver's cabin is mounted and can pivoted relative to a vehicle frame. Two of the trailing arms are arranged spaced apart from one another in a transverse direction that extends perpendicularly to the longitudinal direction, are connected to one another by a torsion bar spring that extends in the transverse direction, and are arranged at the same height in a vertical direction perpendicular to the longitudinal direction and to the transverse direction, thereby forming a first trailing arm pair. Two other trailing arms are arranged spaced apart from one another in the transverse direction, are arranged at the same height in the vertical direction, and thereby form a second trailing arm pair, which is spaced apart, in the vertical direction, from the first trailing arm pair.

Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.

A self-adjusting, self-damping air spring having a first air spring disposed between a cab and a frame of a vehicle and a second air spring in fluid communication with the first air spring. The second air spring positioned relative to the first to provide an opposition force in response to a change in height of the first air spring. This change in height corresponds to a change in displacement between the cab and the frame. The opposition force provided by the second air spring acting to dampen the changes in displacement.

An air spring has an air-spring lobe made of elastomer material, which is clamped at the lobe ends thereof via connection parts between the sprung mass and the unsprung mass and is connected by way of the connection parts to the fastening parts of the sprung and the unsprung mass. The connection parts and the air-spring lobe enclose the working chamber that is under internal pressure and contains the air-spring volume. The working chamber is in connection with at least one air connection provided in the connection parts. At least one of the connection parts is connected to the associated fastening part by a releasable snap-in or latching connection and the snap-in or latching connection includes at least one air connection, to which a feed line or a hose for the compressed air supply is connected.

A system for level regulation of a driver's cab of a commercial vehicle relative to a chassis of the vehicle includes a spring-loaded bearing in order to support the driver's cab in a sprung manner on the chassis of the vehicle; a distance sensor device arranged to record relative movements and/or a distance between the driver's cab and the chassis of the vehicle; and a control device that is arranged for variable control of the spring-loaded bearing, wherein signals of the distance sensor device are used to control the spring-loaded bearing. The spring-loaded bearing can be adjusted to a first height position (h1), so that the distance between the driver's cab and the chassis of the vehicle is controlled by the control device to a first target distance. The spring-loaded bearing can be adjusted to at least one second height position (h2), so that the distance between the driver's cab and the chassis of the vehicle is controlled by the control means to a second target distance. The control means device adjusts the spring-loaded bearing to the first height position (h1) or to the at least one second height position (h2) depending at least on a parameter relating to a driving route and/or a vehicle state.

A height control linkage for a vehicle cab suspension comprising upper and lower linkage members which are adjustably joined by a barrel assembly including first and second barrel members which are selectively joined together. The upper linkage member includes a laterally facing socket and a shaft portion which extends therefrom with the shaft portion having a plurality of alternating and spaced-apart annular grooves and ridges which are rotatably secured to the upper ends of the barrel members. The lower linkage member includes a laterally facing socket and a threaded shaft extending upwardly therefrom which is adjustably threadably secured to the lower ends of the barrel members. The length of the height control linkage may be changed by threadably rotating the barrel assembly with respect to the lower linkage member.
