Abstract
A hydraulic braking system is provided for automatically apportioning braking of the wheels of a vehicle in accordance with the load on respective wheels. A plurality of brake control assemblies each dedicated to one of the wheels of the vehicle are coupled to produce braking of the corresponding wheel upon activation of the brake pedal. The degree of actuation of each brake control assembly is controlled by an element which senses load differences between all wheels on the vehicle (including load differences between wheels on either side of the vehicle and between front and rear wheels), and adjusts the degree of actuation of the corresponding brake control assembly accordingly. In an illustrative embodiment each brake control assembly includes a brake control cylinder having a piston movably disposed therein. The pistons are coupled to the brake pedal so as to be maximally advanced into the brake control cylinder when a maximum brake force is applied. The load sensing device is a pendulum which is mounted for displacement along the length and width of the vehicle from a predefined normal position. The pendulum is coupled to each of the pistons so that, in its normal position, all…
