Description

Stabilizer {STABILIZER} The present disclosure relates to a stabilizer capable of suppressing the rolling behavior of a vehicle. While driving, if the vehicle is on a curve or turning to the left or right, rolling behavior occurs due to inertia, causing the left or right side of the vehicle to lift relatively. To suppress this rolling behavior, a stabilizer may be applied to the underside of the vehicle body. Specifically, the stabilizer is bar-shaped, extending along the width of the vehicle, with both ends connected to knuckle arms or similar components to connect to the vehicle's wheels. Some stabilizers have a single bar shape and possess uniform rigidity. Because stabilizers with uniform rigidity produce poor ride comfort during normal driving, some stabilizers split the bar into left and right sections, installing (hydraulic or electric) actuators between them to control the stabilizer's rigidity according to driving conditions. The matters described as background technology above are intended only to enhance understanding of the background of the present disclosure and do not constitute prior art already known to those skilled in the art. FIG. 1 illustrates a stabilizer according to one embodiment of the present disclosure. FIGS. 2 and FIGS. 3 respectively illustrate the first connecting part and the second connecting part constituting the stabilizer. FIG. 4 illustrates the other side (housing) of the first connecting part, and FIG. 5 illustrates the other side (inner core) of the second connecting part. FIG. 6 shows the housing of the first connecting part and the inner core of the second connecting part connected, and FIG. 7 shows the AA cross-section of FIG. 6. FIG. 8 illustrates the internal structure of a stabilizer with a portion cut off according to one embodiment of the present disclosure. Figure 9 shows a graph regarding the stiffness of the stabilizer. FIG. 10 illustrates the BB cross-section of FIG. 6 to explain an elastic member having a stopper portion formed thereon.
