A suspension includes a knuckle to which a wheel of a vehicle is fastened, a steering drive portion connected to the knuckle, a lower arm positioned at a lower end portion of the steering drive portion and including a first end portion connected to the knuckle and a second end portion connected to a vehicle body frame, a connecting link including a first end portion connected to an upper end portion of the steering drive portion, an upper arm connected to a second end portion of the connecting link, a damper connecting the upper arm and the vehicle body frame, and a push rod including a first end portion connected to the upper arm and a second end portion connected to the lower arm.

A vehicle includes first and second wheel assemblies, a steering wheel, a driver-actuatable input supported on the steering wheel, and an active stabilizer bar. The stabilizer bar has a first end connected to the first wheel assembly, a second end connected to the second wheel assembly, and a coupler connected between the first and second ends and configured to provide a variable torsion force between the first and second ends. A controller is programmed to, in response to actuation of the driver-actuatable input, command the coupler to modify the torsion force.

A suspension system includes a rotation inducing member for causing a cylinder to rotate relative to piston rod in response to an axially-applied force. In examples, the rotation inducing member may be embodied as a bushing structure. In other examples, the cylinder and/or the piston rod may include the rotation inducing member. The inducement of rotational motion may help overcome stiction or similar frictional forces between the piston rod and the cylinder.

Provided is a rotary damper that makes it possible to adjust braking torque characteristics. A rotary damper (1) that restricts the movement of a viscous fluid (6) with which the inside of a cylindrical chamber (200) of a case (2) has been filled and thereby generates braking torque against applied rotational force. A flow path (208) is formed in a partitioning part (204) of the cylindrical chamber (200), and a check valve (3) is movably arranged inside the flow path (208). When a rotor (4) has rotated in a normal rotation direction R1, the check valve (3) moves inside the flow path (208) in a closing direction M1 and closes the flow path (208) and, when the rotor (4) has rotated in a reverse rotation direction R2, moves inside the flow path (208) in an opening direction M2 and opens the flow path (208). The check valve (3) comprises a reaction force application part (302) that generates a reaction force against the check valve (3) when the check valve (3) has moved to a prescribed position in the closing direction M1.

A vehicle damper includes: a movable member that moves with linear motion according to a load applied from a wheel; a conversion member that converts the linear motion of the movable member into rotational motion; an electric motor having a rotor that rotates in conjunction with the rotational motion; a motor housing that houses the electric motor; and a damper mount housing that is fixed to a vehicle body and connected to the motor housing via a first elastic member. The vehicle damper dampens the linear motion of the movable member by an electromagnetic force of the electric motor. The vehicle damper has a second elastic member that is provided for at least one of the motor housing or the damper mount housing and abuts on the other of the motor housing or the damper mount housing when the motor housing and the damper mount housing approach each other.
