Suspension device of vehicle
Suspension arms comprise five arms of a trailing arm, a leading arm, an upper arm, a lower arm, and a control arm. A lower-arm connection portion of a knuckle to the lower arm is positioned in front of a trailing-arm connection portion of the knuckle to the trailing arm as well as a wheel axis. Accordingly, the anti-swing rigidity of a wheel can be increased sufficiently.
1. A suspension device of a vehicle, comprising:
a knuckle supporting a wheel at a wheel axis;
a trailing arm extending rearward from a trailing-arm support point on a vehicle-body side and connected to a trailing-arm connection portion of the knuckle which is positioned below the wheel axis;
a leading arm extending forward from a leading-arm support point on the vehicle-body side and connected to a leading-arm connection portion of the knuckle which is positioned above the wheel axis;
an upper arm extending in a vehicle width direction from an upper-arm support point on the vehicle-body side and connected to an upper-arm connection portion of the knuckle which is positioned above the wheel axis;
a lower arm extending in the vehicle width direction from a lower-arm support point on the vehicle-body side and connected to a lower-arm connection portion of the knuckle which is positioned below the wheel axis; and
a control arm extending in the vehicle width direction from a control-arm support point on the vehicle-body side, arranged in back of the lower arm, and connected to a control-arm connection portion of the knuckle which is positioned below the wheel axis,
wherein said lower-arm connection portion of the knuckle is positioned in front of said trailing-arm connection portion of the knuckle as well as the wheel axis, and
said control-arm connection portion of the knuckle is positioned in back of said trailing-arm connection portion, leading-arm connection portion, upper-arm connection portion, and lower-arm connection portion of the knuckle.
2. The suspension device of a vehicle of claim 1 , wherein, a cross point of an extension line of said leading arm and another extension line of said upper arm is positioned on a vehicle-outward side of the wheel axis and in front of the wheel axis in a plan view.
3. A suspension device of a vehicle, comprising:
a knuckle supporting a wheel at a wheel axis;
a trailing arm extending rearward from a trailing-arm support point on a vehicle-body side and connected to a trailing-arm connection portion of the knuckle which is positioned below the wheel axis;
a leading arm extending forward from a leading-arm support point on the vehicle-body side and connected to a leading-arm connection portion of the knuckle which is positioned above the wheel axis;
an upper arm extending in a vehicle width direction from an upper-arm support point on the vehicle-body side and connected to an upper-arm connection portion of the knuckle which is positioned above the wheel axis;
a lower arm extending in the vehicle width direction from a lower-arm support point on the vehicle-body side and connected to a lower-arm connection portion of the knuckle which is positioned below the wheel axis; and
a control arm extending in the vehicle width direction from a control-arm support point on the vehicle-body side, arranged in back of the lower arm, and connected to a control-arm connection portion of the knuckle which is positioned below the wheel axis,
wherein said lower-arm connection portion of the knuckle is positioned in front of said trailing-arm connection portion of the knuckle as well as the wheel axis,
said trailing-arm connection portion of the knuckle is positioned in the vicinity of the wheel axis in a plan view, and
said control-arm connection portion of the knuckle is positioned in back of said trailing-arm connection portion, leading-arm connection portion, upper-arm connection portion, and lower-arm connection portion of the knuckle.
4. The suspension device of a vehicle of claim 3 , wherein, a cross point of an extension line of said leading arm and another extension line of said upper arm is positioned on a vehicle-outward side of the wheel axis and in front of the wheel axis in a plan view.
5. A suspension device of a vehicle, comprising:
a knuckle supporting a wheel at a wheel axis;
a trailing arm extending rearward from a trailing-arm support point on a vehicle-body side and connected to a trailing-arm connection portion of the knuckle which is positioned below the wheel axis;
a leading arm extending forward from a leading-arm support point on the vehicle-body side and connected to a leading-arm connection portion of the knuckle which is positioned above the wheel axis;
an upper arm extending in a vehicle width direction from an upper-arm support point on the vehicle-body side and connected to an upper-arm connection portion of the knuckle which is positioned above the wheel axis;
a lower arm extending in the vehicle width direction from a lower-arm support point on the vehicle-body side and connected to a lower-arm connection portion of the knuckle which is positioned below the wheel axis; and
a control arm extending in the vehicle width direction from a control-arm support point on the vehicle-body side, arranged in back of the lower arm, and connected to a control-arm connection portion of the knuckle which is positioned below the wheel axis,
wherein said lower-arm connection portion of the knuckle is positioned in front of said trailing-arm connection portion of the knuckle as well as the wheel axis, and
a cross point of an extension line of said leading arm and another extension line of said upper arm is positioned on a vehicle-outward side of the wheel axis and in front of the wheel axis in a plan view.
6. The suspension device of a vehicle of claim 1 , wherein said trailing-arm connection portion of the knuckle is positioned in the vicinity of the wheel axis in a plan view.
7. The suspension device of a vehicle of claim 5 , wherein said control-arm connection portion of the knuckle is positioned in back of said trailing-arm connection portion, leading-arm connection portion, upper-arm connection portion, and lower-arm connection portion of the knuckle.
8. The suspension device of a vehicle of claim 5 , wherein said trailing-arm connection portion of the knuckle is positioned in the vicinity of the wheel axis in a plan view.
