Abstract
A wheel suspension device for a vehicle includes a wheel supporting member rotatably supporting a wheel. The wheel supporting member is linked to a vehicle-body side by a first link and a second link, with the second link arranged substantially parallel to the first link in a vehicle width direction. The first link has a projecting portion, and at least one elastic linking portion links the projecting portion to the second link.
Claims20
A suspension device for a vehicle comprising:
- a wheel supporting member configured to rotatably support a wheel;
- a first link having a projecting portion, the first link connecting the wheel supporting member to a vehicle-body side member;
- a second link extending outward from the vehicle-body side and connecting the wheel supporting member to the vehicle-body side;
- and
- at least two elastic connecting bushes positioned substantially along a second axial link line, each connecting bush directly and hingedly connecting the projecting portion to the second link separate and independent of the wheel supporting member.
A suspension device for suspending a wheel supporting member that rotatably supports a wheel, the suspension device comprising:
- first linking means for linking the wheel supporting member and a vehicle-body side member to each other;
- second linking means disposed behind the first linking means in a vehicle forward-backward direction, and linking the wheel supporting member and the vehicle-body side member to each other;
- and
- at least two elastic linking means for elastically linking the first linking means and the second linking means directly to each other along a second axial link line separate and independent of the wheel supporting member, and for permitting the first linking means and second linking means to be relatively displaced.
A method of suspending a wheel supporting member that rotatably supports a wheel, the method comprising:
- displacing a first link and a second link relative to each other in accordance with a displacement of the wheel supporting member in the vehicle forward-backward direction, the first and the second links extending outward in a vehicle width direction and linking the wheel supporting member with a vehicle-body side member, and the first link having a projection portion and being directly, elastically and hingedly connected to the second link substantially along a second axial link line in at least two places separate and independent of the wheel supporting member;
- and
- generating a reactionary elastic force in accordance with the relative displacement.
