Abstract

An independent suspension for use in a front wheel or a rear wheel of an automobile is provided. It produces a varied characteristic of camber variation for a fixed roll center height and a fixed scuff variation and, consequently, improves freedom of suspension design and offers enhanced operational stability. An upper arm is divided into a knucle side upper arm and a vehicle side upper arm, the two upper arms are interconnected so as to be shakeable in the direction of vertical movement of the wheel, and the vehicle side upper arm and a lower arm are interconnected through the medium of a rigid member having the opposite ends thereof adapted for free vibration. This independent suspension is particularly suitable for use in the Wishbone type independent suspension.

Claims7

Dependent claims

An independent wheel suspension for suspending a wheel on a frame of an automotive vehicle, said suspension comprising:

wheel carrier means for rotatably supporting a wheel, said wheel carrier means including an upper and lower portion;
lower arm means connecting said lower portion of said wheel carrier means to said frame;
upper arm means for connecting said upper portion of said wheel carrier means to said frame, said upper arm means including a first upper arm member pivotably connected to said upper portion of said wheel carrier means and a second upper arm member pivotably connected to said second upper arm member at a first vibrating axis;
and
linking means for linking said second upper arm member to said lower arm means,
said linking means moves said second arm member upwardly thereby moving said first vibrating axis upwardly so that a rectilinear length from said wheel carrier means to said frame is shortened by a predetermined length to decrease the distance between said upper portion of said wheel carrier means and said frame when said wheel carrier means moves a distance in an upward direction which is larger than a predetermined value.
