Abstract: A suspension apparatus for a vehicle includes a stabilizer bar, a hydraulic cylinder, a lever, and a link. The stabilizer bar has a torsion bar portion assembled to an axle. One arm portion of the stabilizer bar is assembled to the frame via the hydraulic cylinder and the lever. The hydraulic cylinder is assembled to the frame at a first connection point on the cylinder body. The lever is connected at a second connection point to the arm portion, is connected at a third connection point to the link, and connected at a fourth connection point to the piston rod. The link is connected at a fifth connection point to the cylinder body. The intersection between a straight line passing through the first and second connection points and a straight line passing through the third and fifth connection points is located near the axis of the piston rod.

Abstract: A suspension apparatus for a vehicle includes a stabilizer bar and an oil-hydraulic cylinder for controlling the stiffness of the stabilizer bar. The stabilizer bar is mounted to the vehicle body to be rotatable about a first axis via a laterally extending torsion bar portion thereof. A left arm portion of the stabilizer bar connected to the oil-hydraulic cylinder includes first and second arm sections. The first arm section extends forward from the left end of the torsion bar portion. The second arm section, which extends in the fore-aft direction, is connected to the distal end of the first arm section via a rubber bushing to be rotatable about a second axis. The second arm section includes a rubber bushing provided at a portion through which the first axis passes. The oil-hydraulic cylinder is connected to the rubber bushing via a bracket.
