Description

Stabilizer device for vehicle {STABILIZER DEVICE FOR VEHICLE}

The present invention relates to a vehicle stabilizer device, and more particularly, to a vehicle stabilizer device for preventing the stabilizer bar torsion due to the amount of impact input to the wheel while the vehicle is running.

In general, a vehicle stabilizer bar is a type of torsion spring that is applied to an independent suspension device to maintain the parallelism of the vehicle body by suppressing rolling motion of the vehicle body when turning or driving on rough roads.

Looking at the conventional configuration of such a stabilizer bar, as shown in FIG. 1, the stabilizer bar 100 has a lower control arm (106, 108) or strut assembly (110, 112) via control links (102, 104) at both ends thereof, respectively. ), And both inner portions of the straight portion inside thereof are fixed to the subframe 114 via the mounting bushes 116 and 118.

The stabilizer bar 100 as described above supports the left and right wheels generated when the vehicle body is rolled, and does not receive force when the left and right wheels move in phase and torsion when they move in reverse phase. By restraining the left and right wheel movement by the elastic force serves to suppress the roll behavior of the vehicle body.

However, in the conventional stabilizer bar 100 system as described above, when the left and right wheels operate in the same phase, no distortion may occur in terms of improving the ride comfort, but the left and right control links 102 and 104 are not connected in a variable manner. Since the stabilizer bar 100 is twisted due to the phase difference of the small stroke, there is a problem that a complaint about the riding comfort of the driver is raised.

Embodiments of the present invention are to provide a stabilizer device for a vehicle for controlling the torsion angle of the stabilizer bar due to the amount of impact input to the wheel while driving the vehicle, by applying a sliding link structure on both ends of the stabilizer bar.

According to an embodiment of the present invention, a stabilizer device for a vehicle includes a stabilizer bar mounted on a subframe of a vehicle through a mounting bush, and interconnects both ends of the stabilizer bar and the strut assembly of the vehicle, and generates vibrations during driving of the vehicle. It may include a stabilizer link unit that is variable in length so as to absorb the torsion of the stabilizer bar by controlling the twist angle of the stabilizer bar.

In the vehicle stabilizer device, the stabilizer link unit has one end connected to the housing, the strut assembly, and the other end connected to an upper rod inserted into the housing, and one end connected to both ends of the stabilizer bar. A lower rod inserted into the housing, a guide member inserted into the housing to be spaced apart from the other end of the upper rod, and a stopper to stop the upper rod from being separated, and the other end of the upper rod; It is interposed between the guide member, it may be made of an elastic member interposed between the other end of the upper rod and the other end of the lower rod.

In the vehicle stabilizer device, a support portion for supporting the elastic member may be formed on the outer circumferential surface of the other end of the upper rod.

In the vehicle stabilizer device, a locking end for supporting the elastic member may be formed on an outer circumferential surface of the other end of the lower rod.

In the vehicle stabilizer device, a locking portion for supporting the elastic member may be formed on an outer circumferential surface of the guide member.

Embodiments of the present invention by applying a sliding link structure on both ends of the stabilizer bar to control the torsion angle of the stabilizer bar due to the amount of impact input to the wheel during driving of the vehicle, it is possible to improve the riding comfort and safety of the driver. .

2 to 5, the vehicle stabilizer device 1 according to an embodiment of the present invention applies a link structure that is slidable at both ends of the stabilizer bar 10 to provide an impact amount input to a wheel during driving of the vehicle. By controlling the torsion angle of the stabilizer bar 10 due to, it is made of a structure that can improve the riding comfort and safety of the driver.

To this end, the vehicle stabilizer device 1 according to the embodiment of the present invention basically includes a stabilizer bar 10 and a stabilizer link unit 20, which will be described by configuration as follows.

The stabilizer bar 10 is mounted to a subframe (not shown) of the vehicle through a mounting bush 3.

In the embodiment of the present invention, the stabilizer link unit 20 interconnects both ends of the stabilizer bar 10 and the strut assembly (not shown) of the vehicle, and stabilizes the bar 10 by vibration generated while the vehicle is running. The length is varied to absorb the torsion of the control panel and control the torsion angle of the stabilizer bar 10.

Here, the stabilizer link unit 20 includes a housing 29, an upper rod 21, a lower rod 23, a guide member 25, and an elastic member 27.

The housing 29 has a space that can be mounted therein.

One end of the upper rod 21 is connected to the strut assembly, the other end is inserted into the housing 29, and a support part 31 is formed on the outer peripheral surface of the other end of the upper rod 21.

One end of the lower rod 23 is connected to both ends of the stabilizer bar 10, and the other end is inserted into the housing 29, and a locking end 33 is formed at the outer peripheral surface of the other end of the lower rod 23. .
