Abstract: An independent steering device includes a knuckle coupled to a wheel and a driving unit including a motor and a reducer. The motor provides driving force for rotating the knuckle. At least a portion of the reducer is rotatably connected to the knuckle and decelerates a rotational movement of the motor and transmits the rotational movement to the knuckle. The independent steering device further includes a steering angle measuring device coupled to the knuckle and the driving unit and measuring a steering angle of the wheel. The steering angle measuring device includes a body coupled to the knuckle and rotates with the knuckle, a shaft rotatably coupled to the body, and a rod coaxially extending from the shaft and fixed to at least a portion of the driving unit.

Abstract: An independent steering device for a vehicle wheel includes: a knuckle provided with a first upper coupling portion and a second upper coupling portion at an upper portion and a lower coupling portion at a lower portion; a first actuator rotatably coupled to the first upper coupling portion; a second actuator positioned adjacent to the first actuator and rotatably coupled to the second upper coupling portion; and a lower connection member rotatably coupled to the lower coupling portion. The lower coupling portion may be positioned below a center of the knuckle between the first upper coupling portion and the second upper coupling portion.

Abstract: An independent steering device includes: a knuckle coupled to a wheel; and a driving unit having the knuckle rotatably coupled to at least a portion thereof and providing a driving force for rotating the knuckle. The driving unit may include: a motor having a first rotating shaft; a reducer having a second rotating shaft and coupled to the knuckle; and a power transmission member connecting the first rotating shaft and the second rotating shaft and configured to transmit rotational force between the first rotating shaft and the second rotating shaft. The motor and the reducer may be disposed so that the first and second rotating shafts are parallel.

Abstract: In a vehicular brake-by-wire system, when a motor needs to generate brake hydraulic pressure, but fails to drive due to a trouble with the motor, a failure in the controller, or the like, a driver operates a pneumatic cylinder by operating pneumatic valve switch, and a master cylinder operates by the operation of the pneumatic cylinder, thereby possibly generating brake hydraulic pressure for vehicular braking.

Abstract: An embodiment suspension system for a vehicle includes a rocker arm housing coupled to a first end of a lower arm through which a rotation axis passes, a rocker arm having a first end surrounded by the rocker arm housing and a second end disposed toward a center of the rocker arm housing, the rocker arm being rotatable together with the lower arm about the rotation axis, a torsion bar having a first end connected to the second end of the rocker arm and a second end extending along the rotation axis and then coupled to a vehicle body connection member, and a contact protrusion disposed on either the rocker arm housing or the rocker arm, the contact protrusion being configured to come into contact with the other of the rocker arm and the rocker arm housing in accordance with a rotation angle of the rocker arm housing.
