Abstract:
A monotube damper and suspension spring assembly comprising:a tubular housing member having an open end, a closure member closing the open end and being axially slidable relative to the tubular housing member, the tubular housing member and closure member defining a variable volume chamber filled with damping fluid, a piston sealingly mounted in the tubular housing member and axially slidable relative to the tubular housing member and the closure member, a piston rod rigidly mounted on the piston and extending axially out of the chamber through a wall of one of the tubular housing member and the closure member, the piston rod being adapted for attachment to one of a body and a wheel apparatus of a vehicle, a first spring seat fixed relative to the piston rod outside the chamber, a second spring seat fixed relative to the one of the tubular housing member and closure member, the other of the tubular housing member and the closure member being adapted for attachment to the other of a body and a wheel apparatus of a vehicle, and a suspension spring compressible between the first and second spring seats when the assembly is attached between the body and a wheel apparatus of a vehicle to exert a preload force between the tubular housing member and closure member in direction to increase fluid pressure within the chamber.
