Abstract
In a vehicle front suspension of the type wherein a control arm is vertically pivotally mounted to a vehicle body at two inboard end portions thereof spaced apart substantially in the vehicle longitudinal direction through respectively a front and a rear elastic linkage bearing and is horizontally pivotably connected at an outboard end portion thereof with a wheel support member bearing a knuckle arm extending rearwardly and rotatably supporting a vehicle wheel, and the free end of the knuckle arm is pivotably connected with an end portion of a tie rod for steering of the vehicle, the rear elastic linkage bearing is constructed to exhibit non-linear spring characteristics such as to exhibit a first spring constant with respect to force acting thereto in a vehicle lateral direction and not exceeding a certain value and a second spring constant which is lower than said first spring constant with respect to the lateral force exceeding said certain value, and the first spring constant of the rear elastic linkage bearing and the spring constant of the front elastic linkage bearing with respect to force acting thereto in the vehicle lateral direction are set such that the instantaneous center of pivoting of the vehicle wheel support member and the control arm together in the vehicle longitudinal direction is positioned to the rear of the axis of the tie rod.
