Abstract: A suspension system may include a lower arm configured to perform a vibrating movement by vibration of the vehicle, a reducer connected to the lower arm so that the vibrating movement of the lower arm is transmitted thereto, and a motor unit connected to the reducer, and configured to receive power from the reducer. The reducer may include an input shaft unit rotatably mounted to the housing and connected to the lower arm to be rotated by vibration of the lower arm, a gear unit configured to receive a rotating force from the input shaft unit, an output shaft unit configured to receive power from the gear unit, and a clutch unit selectively connecting the gear unit with the output shaft unit.

Abstract: An electric damper for a vehicle may include: a housing body fixed to a vehicle body; a gear bar including a first end coupled to a knuckle of a wheel, and a second end extending into the housing body, with a rack gear provided on the gear bar; a first intersection gear unit installed in a direction intersecting a movement direction of the gear and configured to engage with the rack gear and rotate; a first power transmitting gear unit configured to engage with the first intersection gear unit and rotate, and including a rotating shaft installed parallel to the gear bar; a rotator configured to engage with the first power transmitting gear unit, and provided in a shape enclosing an outer surface of the gear bar; and a stator installed in the housing body at a position facing the rotator and having a magnetic force.

Abstract: In an electric power generating apparatus using a suspension device according to an embodiment of the present invention, provided is a valve structure for partially disconnecting a suspension device (or a damper) from an energy recovery device (or a turbine unit) when a vehicle is driving on an under-construction road or an unpaved road from which a large bump is expected.

Abstract: Disclosed is a backlash reduction mechanism that can stably control the position of a vehicle, using a backlash reduction unit for reducing backlash of a reduction gear in a vehicle capable of actively controlling roll, and an actuator of a vehicle equipped with the backlash reduction mechanism. Further, the present invention provides a torsion damper capable of stably controlling the position of a vehicle capable of controlling roll, and an actuator of a vehicle equipped with the torsion damper. Further, the present invention provides a coaxial-aligning part that compensates for left-right inclination through stabilizers by generating a torsional force in a vehicle capable of actively controlling roll, and an actuator of a vehicle equipped with the coaxially-aligning part.
