ABSTRACT:
An off-highway vehicle suspension system strut of the type employing rubber impact pads to provide damping is modified by conversion of the housing to accommodate a nitrogen-over-oil suspension system. The rubber pads are removed and the inner barrel is capped with a piston. The outer barrel is fitted with a gas inlet valve, and an interface between the two barrels is created by a combination of one-way and two-way valves. Appropriate wall sections in the two barrels are reinforced or replaced to create adequate strength for hydraulic operation, and the barrels are linked by a stop rod that permits limited telescopic movement.
