A suspension arrangement for the wheels of vehicles comprising links ( 1 & 2 ), of equal pivotal length rotatably attached to the chassis or body at one end, at upper and lower chassis attachment points ( 3 & 4 ), and an axle support link ( 7 ), locating a wheel axle ( 8 ), at one end and attached at its other ends ( 5 & 6 ) to the opposite ends of the links ( 1 & 2 ). The spacing between attachments ( 3 & 4 ) is double that between ( 5 & 6 ) and the centre distance between the axle and its link attachment points is the same as the pivotal length of links ( 1 & 2 ). The geometry of said arrangement constrains the movement of the axle/wheel rectilinearly between the chassis attachment points and the angular displacement of the axle support link focuses to an axis ( 10 ), exhibiting slight rectilinear displacement.
