Problems solved by technology

[0004] The use of helical gears will generate thrust. At this time, if there is a gap between the shafts, the gears will be moved axially by the thrust, which will cause problems that are unfavorable to efficiency and noise.
[0005] Moreover, the actuators that make up the traditional ARS have no sensors that can grasp the relative angle of the stabilizer bar other than the sensors required for the rotation of the motor, and must rely on the vehicle height sensor or other external signals from the actuator.

Abstract

The invention provides an actuator of a vehicle and an apparatus for controlling posture of a vehicle with the said actuator. The actuator includes a gap reducing mechanism for axially pre-pressing gears inside, and a position sensor assembled close to a motor inside. The actuator of a vehicle also includes a fixed stabilizer bar fixed to one side of a housing; a rotary stabilizer bar assembled to the other side of the housing in a rotary manner; a central gear, a planetary gear, a support, and a multi-stage planetary gear unit; a stator which generates magnetic forces when being powered on, a rotor rotating through the magnetic forces, and the motor assembled inside the housing; and the gap reducing mechanism for axially pre-pressing the central gear at one side of the multi-stage planetary gear unit. Through adoption of the actuator, the vehicle is prevented from tilting leftwards or rightwards to the maximum, so active side tilting prevention effects are achieved. Passengers feel much safer, and inconvenience brought to passengers, caused by tilting and cornering of the vehicle, is eliminated, and a vehicle driving effect is improved.

Description

technical field [0001] The present invention relates to an actuator for a vehicle fitted between stabilizer bars supporting each side wheel and a vehicle posture control device for controlling the posture of a vehicle using the actuator. Background technique [0002] ARS (Active Roll Stabilizer) is a device that changes the rigidity of the stabilizer bar (Stabilizer Bar) to enhance vehicle stability and ride comfort. This ARS suppresses the vehicle's roll and enhances stability when the vehicle is turning, or distributes the roll rigidity of the front and rear wheels to control the lateral posture of the vehicle. ARS reduces the rigidity of the stabilizer bar when the vehicle is going straight, reduces the impact from the road surface and improves the ride quality. [0003] Korean Laid-Open Patent No. 2008-0040058 introduces an ARS consisting of left and right stabilizer bars. However, the coaxial precision of this ARS will decrease when the left and right stabilizer bars ...
