Abstract
A rear suspension system includes an axle carrier rotatably carrying the road wheel. The axle carrier is connected to the vehicle body via a front lateral link, a rear lateral link, a radius rod and a vertical strut. The front lateral link is shorter than the rear lateral link and has an outboard end pivotably mounted via an elastic bush on the axle carrier at a front pivot portion thereof. The outboard end of the front lateral link is disposed inboard of an outboard end of the rear lateral link. With this arrangement, a toe angle of the outer rear wheel is varied to a toe-in side when the vehicle makes a turn. Thus, the vehicle exhibits a compliance understeer characteristic while making a turn.

A rear suspension system for a vehicle having a vehicle body with a vehicle longitudinal axis and a road wheel, comprising:
- an axle carrier rotatably carrying the road wheel;
- lateral link means for pivotably connecting said axle carrier with regard to the vehicle body, said lateral link means including outboard ends pivotably mounted on said axle carrier at a front pivot portion and a rear pivot portion, respectively;
- said front pivot portion being disposed inboard of said rear pivot portion with respect to the vehicle;
- and
- a radius rod having a rear end pivotably mounted on said axle carrier at a third pivot portion and a front end pivotably supported by the vehicle body, wherein said front pivot portion is so disposed inboard of said third pivot portion as to provide an arrangement whereby said lateral link means do not interfere with said radius rod even if said radius rod extends upward with respect to the vehicle from said rear end toward said front end thereof at an increased angle.
