    Abstract: In a suspension for a steerable wheel of a motor-vehicle, with a semi-virtual steering axis, the wheel support (M) is connected to the vehicle structure by an upper arm (B) and two lower rods (A1, A2), one of which (A2) supports the lateral loads, whereas the other (A1) supports the longitudinal loads and is located forwardly with respect to the rod (A2) which supports the lateral loads. In a condition of non-steered wheel, the articulated joint (S5) which connects the lower rod (A1) which supports the longitudinal loads to the wheel support (M) is located more outwardly, i.e. is spaced more far away from the median longitudinal vertical plane of the motor-vehicle with respect to the articulated joint (S6) which connects the lower rod (A2) which supports the lateral load to the wheel support (M). The arrangement is such that during steering with a wheel being on the outer side of the curve, the point of intersection of the projections on a horizontal plane of the two lower rods (A1, A2) is displaced more inwardly, causing a less inclined orientation with respect to the vertical of the steering axis of the wheel. In the condition of steered wheel, with said wheel being on the inner side of the curve, the projections on a horizontal plane of said lower rods (A1, A2) meet at a point (AX') displaced longitudinally forwardly with respect to the position (AX) of this intersection point in the condition of non-steered wheel, so that the steering axis, in a lateral view, forms a caster angel (”) with respect to the vertical direction which is greater than the value of the same angle in the condition of non-steered wheel.
