DUAL TUBE LOAD DISTRIBUTION UNIT FOR VEHICLE SUSPENSION SYSTEM

A suspension system (100) including hydraulic circuits that extend between dampers located at opposite corners of the vehicle and at least one load distribution unit (104) that is connected in fluid communication with at least two hydraulic circuits. The load distribution unit (104) includes a manifold block (115) with a cylinder bore (117a), a pair of pressure tubes (119a, 119b), a piston rod assembly (168a), and a pair of reserve tubes (131a, 131b). The pressure tubes (119a, 119b) are partially received in the cylinder bore (117a) to define a pair of opposed cylinders. The piston rod assembly includes a piston rod (158) and a pair of opposed pistons (170a, 170b) that are slidingly received within the opposed cylinders. The reserve tubes (131a, 131b) are at least partially received in the cylinder bore (117a) and are arranged annularly about the pressure tubes (119a, 119b) to define a first pair of reservoir chambers between the pressure tubes and the reserve tubes.
