An actuator device (1) for an adjustable roll stabilizer (2) of a motor vehicle, with a housing (4) that extends in the direction of a rotational axis (3) and an actuator (5) arranged in the housing. The actuator device (1) can be operated to twist two stabilizer sections (7a, 7b) relative to one another about the rotational axis (3) and the two stabilizer sections (7a, 7b) are attached to opposite ends (6a, 6b) of the actuator device (1). An engagement contour (8) is formed on the housing (4), which is suitable for immobilizing the housing during the application of torque (M1) to the housing (4) in a direction around the rotational axis (3).

A vehicle height adjustment device of the present invention includes a motion conversion unit that includes a rotating member and a linear motion member, and that converts a rotational motion of the rotating member into a linear motion of the linear motion member, a plurality of motors, a driven gear coupled to the rotating member, a plurality of drive gears that meshes with the driven gear, and a spring seat that is coupled to the linear motion member, and that supports one end of a suspension spring interposed between a vehicle body and an axle of a vehicle, wherein after driving the spring seat and then stopping the spring seat, some drive gears of the drive gears are driven in a direction opposite a drive direction of the spring seat.

A method of controlling relative roll torque in vehicles having a front active sway bar and a rear active sway bar is provided. The front active sway bar varies roll torque of a front axle and the rear active sway bar varies roll torque of a rear axle. The method includes monitoring dynamic driving conditions during operation of the vehicle and biasing tire lateral load transfer distribution (TLLTD) relative to the front axle based on the monitored dynamic driving conditions. Positive bias of the TLLTD increases the portion of a total roll torque carried by the front active sway bar. Biasing TLLTD occurs during one or more dynamic bias events triggered as monitored dynamic driving conditions exceed one or more calibrated thresholds.

A roll stabilizer for a motor vehicle includes a torsion bar and a vibration damper located on the torsion bar. The vibration damper is configured to vibrate relative to the torsion bar. The vibration damper includes two half-shells formed together about the torsion bar. Damper elements are disposed between the half-shells. The damper elements can be adjusted via an adjustment component to alter the rigidity of the damper elements.

A spring apparatus (10), including: a spring (12); an elongated object (18A) disposed within and along the spring (12); and a mode-changing assembly (16), for providing a first mode in which a portion (38) of the spring (12) being along the elongated object (18A) is not springy, and a second mode in which an entire of the spring (12) is springy.

A coupling structure of suspension may include an assist knuckle, a RevoKnuckle rotatably engaged with the assist knuckle, rotated independently from the assist knuckle, and performing steering of a wheel located at an outermost periphery, a steering input portion fixed to a vehicle body and applying a steering force to the RevoKnuckle during steering, a rotation transfer unit located between and coupled between the RevoKnuckle and the steering input portion and absorbing angular displacement formed between the steering input portion and the RevoKnuckle, a first link unit having one end located on one side surface of the assist knuckle and the other end located at a lower end of the RevoKnuckle, and a second link unit having one end located on the other side surface of the assist knuckle and the other end located adjacent to the other end of the first link unit at the lower end of the RevoKnuckle.

Provided is a steering device of an independent drive wheel, the steering device including a base frame coupled to a vehicle body; a drive device coupled to the base frame and driven to rotate an output shaft; a steering knuckle connecting the base frame and the wheel through an upper arm and a lower arm spaced apart from each other in the up/down direction; and a connecting device having one end connected to the output shaft of the drive device and the other end, which extends in the longitudinal direction, connected to a steering knuckle below the upper arm to transmit the driving force of a drive device to rotate the steering knuckle in the same direction as the extending longitudinal direction.

Suspension systems for recreational vehicles are disclosed. The suspension systems may include at least one adjustable member coupling a sway bar to respective suspensions. The suspension systems may include a torque actuator associated with a sway bar.
