A suspension device for vehicles (a front suspension ()) is disclosed in which, of connecting portions () of a lower arm () and a tie rod () for connection to a knuckle (), one of the connecting portions () which is close to the rear of the vehicle is offset inward in the vehicle width direction with respect to the other connecting portion () which is close to the front of the vehicle, in the steering neutral state. The center (P) of a lower end portion of a coil spring () is offset outward in the vehicle width direction and rearward in the vehicle's longitudinal direction with respect to the center (P) of an upper end portion of the coil spring ().

Suspension device for vehicles

A rear suspension apparatus for a motor vehicle having a differential gear case ( ) disposed between rear right- and left-wheels ( R, L), which is of a torsion beam type. In the rear suspension apparatus, a central portion ( ) of a torsion beam ( ) for rotatably supporting the rear right- and left-hand wheels ( R, L) is curved to run along the configuration of the differential gear case ( ), and is disposed at the rear of the differential gear case ( ). A suspension damper ( ) stretched between the torsion beam ( ) and the vehicle body is disposed to be inclined upwardly and forwardly.

Rear suspension apparatus for motor vehicle

In a torsion beam type rear suspension, a joint seat (,) with a torsion beam (,) is formed on each lower spring seat (,) to define an upward slope from the outer side to the inner side in the widthwise direction of the vehicle body to suppress separation of the spring seats and cracking of the beam.

Suspension apparatus for a vehicle

A cylinder unit for adjusting a vehicle height of the vehicle body is interposed separately or independently between the vehicle body and each wheel. The supply and discharge of the operating fluid to and from each of the cylinder units is performed by generating a control signal indicative of the quantity of supplying and discharging the operating fluid to and from the flow rate adjusting valves. The control signal is determined so as to allow an actual angle of a roll of the vehicle body to agree with a target angle of the roll thereof. When the automotive vehicle is cornering, particularly rapidly, the control signal is corrected in such a manner that the larger the inner pressure of the cylinder unit, the smaller the quantity of the operating fluid to be supplied or to be discharged. Specifically, the correction is made so as to minimize the quantity of the operating fluid to be supplied to or to be discharged from the cylinder unit on the outer wheel side upon cornering, which has a higher inner pressure, and to maximize the quantity of the operating fluid to be supplied to or to be discharged from the cylinder unit on the inner wheel side upon cornering, which has a lower inner pressure.
