Provided is an active roll control apparatus for controlling a stiffness value of a stabilizer bar by moving the stabilizer bar, which is installed between left and right wheels of a vehicle and extends in a first direction, and a stabilizer link connected with the stabilizer bar to improve turning stability of the vehicle by actively controlling roll stiffness of the vehicle. The active roll control apparatus includes rotating shafts having one ends connected to both ends of the stabilizer bar, moving units into which the rotating shafts are inserted and which are movable along outer side surfaces of the rotating shafts in a second direction perpendicular to the first direction, and a driving unit configured to rotate the rotating shafts to move the moving units.

Rotational inerters are described herein that can provide torque applications in response to a rotation component. The inerter can include a first shaft having a first longitudinal axis and a second shaft having a second longitudinal axis. A first gear can be connected with the first shaft and a second gear can be connected with the second shaft. The first and second gears can be in meshing engagement with one another. In some arrangements, the first gear can be a worm gear and the second gear can be a worm. A flywheel can be connected with the second shaft. Rotation of the first shaft can cause the second shaft to rotate. Arrangements described herein can cause a torque to be applied at the first shaft that is proportional to a rate of change of the angular velocity of the first shaft about the first longitudinal axis.

An elastic chassis link for a vehicle is disclosed. The elastic chassis link includes a sliding joint having first and second sliding joint rods. The joint rods are movable axially relative to each other in order to change the rigidity of the elastic chassis link. The first sliding joint rod is connected to a piston that is arranged axially and movable axially within a piston space within second sliding joint rod. The piston divides the piston space into two chambers that interact with a damping element, such as fluid, within each chamber.

The present invention relates to an active suspension system allowing the force acting axis of a spring to be controlled, wherein a control means for the force acting axis of a spring is installed either between an upper seat plate and an upper arm, or between a lower seat plate and a lower arm so as to allow the wheel rate and vehicle height to be controlled by varying the force acting axis of the coil spring, and a manipulation unit capable of controlling the operation of the control means for the force acting axis of a spring is installed inside the vehicle. By varying the force acting axis of the coil spring, the present invention can significantly improve the marketability of the suspension system and reliability of the vehicle by varying the ride quality.

A three-wheeled vehicle having a front wheel assembly attached to a chassis. The chassis includes a rotational control shaft having a rotational axis that is generally directed in a longitudinal direction of the vehicle. The rotational control shaft is integrated with or secured to the chassis in a non-rotational manner and passes through the front wheel assembly in a rotationally-free manner, such that the rotational control shaft can rotate about its rotational axis. The front wheel assembly includes one or more lean control motors, which are operably configured to rotate the rotational control shaft about its rotational axis thereby causing the chassis to lean from side to side to improve the handling ability of the vehicle. Some embodiments include a lean control system configured to automatically control the degree of rotation of the chassis.

A vehicle ride height adjustment system includes a vehicle chassis. A wheel is connected to the vehicle chassis by a suspension system. A shock absorber and spring assembly are connected to the vehicle chassis and the shock absorber and spring assembly are connected to the suspension system by a height adjustment mechanism.
