ABSTRACT:
A vehicle suspension system includes a vehicle sprung mass and a suspension control arm connected to and being a part of the unsprung mass. A suspension spring seats on an upper spring seat on the vehicle frame and on a lower spring seat mounted on the control arm. A brake actuating pressure proportioner is mounted on the control arm and has a spring loaded proportioning piston therein for proportioning the brake pressure through the proportioner. A plunger loads the proportioning spring to establish the brake pressure point at which proportioning action begins. A cap fits over the outer end of the plunger and is movable with the plunger. The lower spring seat engages levers which are fulcrumed on a portion of the control arm at their outer ends and on a flange of the cap at their inner ends, the points of engagement of the lower spring seat being intermediate the lever ends, so that a proportionate amount of the vehicle load exerted through the suspension spring is transmitted to the proportioner plunger and the remainder of the load is transmitted directly to the control arm. The spring seat therefore loads the plunger and the proportioning spring and the proportioning piston in accordance with the load on the suspension spring to modify the proportioning action of the proportioning piston in accordance with changes in vehicle load as represented by the load on the suspension spring.
