Description

Active Roll Stabilizer

The present invention relates to an active roll stabilizer.

In general, a stabilizer is often provided to improve the stability of the vehicle body when the vehicle is turning or rolling.

When the left and right wheels of the vehicle operate vertically, the stabilizer rotates the stabilizer bar formed in the longitudinal direction using the actuator to generate the restoring force, thereby reducing the inclination of the vehicle body.

On the other hand, the actuator is provided with a motor for driving the stabilizer. The motor can be operated in conjunction with an external power source. In general, the connection between the motor and the external power supply is made through wires.

However, when the motor and the wire are connected, the motor is located inside the closed housing, and it is a matter of which portion of the housing is connected to the wire. In addition, when the wire is routed to the cover located on the front surface of the housing or the shaft of the motor, foreign matter or water may enter the motor because the external environment and the blocking are not perfect.

In addition, a conventional stabilizer is electronically controlled by an actuator, so that the stabilizer bar often operates beyond the maximum driving force set at the time of rotation.

In this case, since the stabilizer bar is twisted more than the rotation angle of the target value, the stability of the vehicle body is not only lowered but also the fixing and abrasion of the apparatus is caused. In addition, there is a problem that the actuator must be operated even in low vibration when driving on unpaved roads and general roads.

Claims (10)

A pair of stabilizer bars including a first stabilizer bar and a second stabilizer bar installed between the wheels;
And an actuator connected between the pair of stabilizer bars and transmitting rotational force to the pair of stabilizer bars,
Wherein the actuator comprises:
A motor for generating a rotational force;
A housing coupled between the pair of stabilizer bars and having the motor disposed therein;
A wire portion connecting the motor and an external power source; and
And a coupling member coupling the motor and the second stabilizer bar,
The coupling member
A fixed coupler that covers one surface of the motor and is coupled to the second stabilizer bar;
A waterproof cover coupled to the fixed coupler to prevent foreign matter or liquid from penetrating into the wire portion or the motor,
And a lock screw for fixing the fixed coupler and the waterproof cover.
The method according to claim 1,
The waterproof cover
A waterproof body portion in which a first coupler through hole is formed so that the fixed coupler passes through the central region;
And a wire cover portion formed to surround the wire portion and protruding in a direction toward the fixed coupler and having a first through hole through which the wire portion penetrates.
3. The method of claim 2,
The fixed coupler includes:
A fixed coupler body portion having a disk shape;
And a fixed coupler protrusion protruding outward from one end of the fixed coupler body and having a hollow portion for coupling the second stabilizer bar to the inside thereof.
The method of claim 3,
A second through hole is formed in the body of the fixed coupler so as to penetrate the wire portion, and the wire cover portion is inserted into the second through hole.
5. The method of claim 4,
Wherein the second through hole is provided in an arc shape.
5. The method of claim 4,
Wherein the engaging member further includes a shaft fixing cover positioned between the waterproof cover and the lock screw to protect the waterproof cover.
The method according to claim 6,
Wherein the shaft fixing cover is provided in the form of a disk, a second coupler through hole is formed in a central region of the shaft fixing cover so that the fixed coupler projection passes through,
And a third through hole is formed in the edge region of the shaft fixing cover so that the wire penetrates through the through hole.
8. The method of claim 7,
Wherein the first through hole, the second through hole, and the third through hole are located opposite to each other.
The method according to claim 1,
Wherein the lock screw is positioned to surround the shaft fixing cover, and a third coupler through hole is formed in the lock screw so that the fixing coupler passes through the lock screw.
10. The method according to any one of claims 1 to 9,
Wherein the waterproof cover is made of a rubber material.
