An adjustable anti-roll bar arrangement for a vehicle, comprising a bracket configured to be mounted in a fixed relationship to a chassis or a an axle of the vehicle, a linear actuator connected to the bracket, a guided element, the linear actuator being configured to drive the guided element along a first geometrical axis, a supporting shaft mounted to the bracket and defining a second geometrical axis which has a different extension compared to the first geometrical axis, an anti-roll bar, and a stabilizer stay having a first end connected to the anti-roll bar, and a second end movably connected to and supported by the supporting shaft, the second end being also connected to the guided element such that when the linear actuator drives the guided element along the first geometrical axis, the second end follows the motion along the second geometrical axis. The invention also relates to a vehicle comprising such an arrangement.

In a stabilizer device, a stabilizer bar having both ends connected to right and left wheel holding portions is supported at a pair of right and left supported portions of the stabilizer bar by a vehicle body via a pair of cylinders that can be extended and retracted based on vertical movement of wheels. The stabilizer device includes two communication passages, each of which allows one of two liquid chambers of one of the pair of cylinders and the other of two liquid chambers of the other cylinder to communicate with each other. The stabilizer device further includes an inter-passage communication passage that allows the two communication passages to communicate with each other, and an on-off valve that is opened and closed to open and close the inter-passage communication passage.

A sway bar system is described. The sway bar system includes a sway bar having a first end and a second end. An electronically controlled connector to provide a remotely controllable physical connection and disconnection capability between a first location on a vehicle and the first end of the sway bar; and the second end of the sway bar coupled to a second location on the vehicle.

The ECU of the stabilizer control apparatus determines, based on a high frequency component of a wheel acceleration and a low frequency component of a wheel speed difference, whether a road surface state is a rough road state or a smooth road state. When the road surface state is determined to be the rough road state, the ECU sets a turning determination threshold to a rough road threshold. When the road surface state is determined to be the smooth road state, the ECU sets the threshold to a smooth road threshold. When a turning determination parameter is greater than the threshold, the ECU sets each of first, second, and third cylinders to a lock state to increase rigidity of stabilizers. When the turning determination parameter is smaller than the turning determination threshold, the ECU sets each of the cylinders to a free state to decrease the rigidity of the stabilizers.

Disclosed herein is a sway bar system comprising a damping link that couples a first end of a sway bar to a first location on a vehicle. The damping link is comprised of a body comprising a damping chamber and a reservoir. There is also a through shaft coupled to a piston, where the piston divides the chamber into a first chamber and a second chamber. A high-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the first chamber and the second chamber to the reservoir. A low-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the reservoir to the first chamber and the second chamber. The high-pressure line and the low-pressure line assist in self-centering the sway bar.

There is provided a stabilizer for a vehicle, including a torsion bar fixed to a car body and configured to be rotated about a longitudinal axis of rotation without changing a position, two arm links connected to both ends of the torsion bar, and two drive links connected to each of the two arm links through a ball joint so as to be able to be rotated three-dimensionally, in which the two drive links are configured to, during cornering of the vehicle, adjust a degree of torsion of the torsion bar by rotating about an axis of rotation of a strut assembly or a steering knuckle connected to the two drive links.

This invention pertains to sway bar systems, and a method of controlling their operation. Specifically, the present invention relates to provide a way of adjusting the response characteristics of a sway bar system by changing the structure of the typical sway bar links and regulating the modified structure by utilizing an electronically adjustable sway bar link. Said electronically adjustable sway bar link comprises a twin tube cylinder filled with mixed incompressible fluid and pressurized gas and forms a determined volume in order to host pressurized gas higher than fluid flow regulation functions, permitting a directional control valve to always remain fully submerged in incompressible fluid and to modify the fluid path between each tube of said twin tube cylinder, allowing closed or opened fluid flow operation, determined by a controlling device receiving an electronic input and piloting said directional control valve.

An anti-roll bar for a vehicle. The anti-roll bar includes a first bar portion for connection to a left-side wheel suspension of the vehicle and a second bar portion for connection to a right-side wheel suspension of the vehicle, and an actuator unit connecting the first bar portion and the second bar portion to each other for transferring torque between the first bar portion and the second bar portion. The actuator unit has a first selectable mode providing a first predetermined torque ratio between the first bar portion and the second bar portion, and a second selectable mode providing a second predetermined torque ratio between the first bar portion and the second bar portion. The first torque ratio and the second torque ratio are different from each other.

A convertible link for use with an anti-sway bar is provided. The convertible link includes a hydraulic cylinder having a link tube and a fluid shaft. The fluid shaft includes a piston coupled to a first end of the fluid shaft, wherein the fluid shaft and the piston are slidably coupled within the link tube. Fluid flows in and out of the hydraulic cylinder to move the hydraulic cylinder between a fixed and a moveable condition. In the fixed position the fluid shaft does not move with respect to the link tube and the anti-sway bar is operational to control roll. In the moveable condition the fluid shaft is moveable with respect to the link tube and the anti-sway bar is not operational to control roll.
