Abstract
A suspension system for a vehicle includes a wheel carrier for rotatably supporting a wheel, an upper control link having a first end coupled to an upper end of the wheel carrier and a second end proximal to a vehicle body, a lower control link having a second end coupled to a lower end of the wheel carrier and a second end proximal to the vehicle body, a reciprocating hydraulic actuator disposed such that its reciprocating motion becomes perpendicular to a vertical direction of the vehicle body, a converter for converting the reciprocating motion of the reciprocating hydraulic actuator into an up-and-own motion of the upper and lower control links, and an electronic control part for controlling an operation of the reciprocating hydraulic actuator in accordance with a driving condition of the vehicle.
Claims11
A suspension system for a vehicle, comprising:
- a wheel carrier for rotatably supporting a wheel;
- an upper control link, a first end of which is connected to an upper end of the wheel carrier and a second end of which is mountable in proximity to a vehicle body;
- a lower control link, a first end of which is connected to a lower end of the wheel carrier and a second end of which is mountable in proximity to the vehicle body;
- and
- a roll controller having a reciprocating hydraulic actuator horizontally disposed to actuate, in a lateral direction of the vehicle, the upper and lower control links simultaneously.
