Abstract:
A damper system for a vehicle including a pressure tube and a piston assembly. A stroke dependent damper assembly is coupled to a piston rod at a position below the piston assembly. A free floating piston positioned in an internal cavity of the stroke dependent damper assembly is longitudinally moveable between retracted, middle, and extended positions. A metering pin extends from the floating piston into a through-bore in a distal end of the stroke dependent damper assembly. An orifice is defined between an inner surface of the through-bore and an outer surface of the metering pin. Longitudinal movement of the floating piston changes the position of the metering pin in the through-bore, which changes the size of the orifice. Fluid flow through the orifice is restricted when the orifice size decreases, which slows down the movement of the floating piston as it approaches the retracted and extended positions.

Claim (Index 1):
A damper system for a vehicle, comprising:\n a pressure tube containing a hydraulic fluid; a piston rod extending within the pressure tube along a longitudinal axis; a first piston assembly slidably fitted in the pressure tube for movement along the longitudinal axis, the first piston assembly coupled to the piston rod and separating the pressure tube into a first working chamber and a second working chamber, the first piston assembly including a first valve assembly that controls fluid flow between the first working chamber and the second working chamber; and a stroke dependent damper assembly including a damper housing coupled to the piston rod, an internal cavity, a floating piston slidably received in the internal cavity for movement between a retracted position, an intermediate position, and an extended position, and a second piston assembly positioned inside the damper housing such that a proximal chamber is defined in the internal cavity of the stroke dependent damper assembly between the second piston assembly and a base portion of the damper housing and such that an intermediary chamber is defined in the internal cavity of the stroke dependent damper assembly between the second piston assembly and the floating piston, the floating piston being unbiased and free floating in the internal cavity, and an end wall that is fixed in place relative to the damper housing, the end wall including a through-bore, and the floating piston including a metering pin received in the through-bore to define an orifice between an inner surface of the through-bore and an outer surface of the metering pin that changes in size when the floating piston moves between the retracted, intermediate, and extended positions, wherein the stroke dependent damper assembly includes a first resilient travel stop positioned in the intermediary chamber between the second piston assembly and the floating piston and a second resilient travel stop positioned in a distal chamber between the floating piston and the end wall, the metering pin configured such that the floating piston contacts the first resilient travel stop in the retracted position and contacts the second resilient travel stop in the extended position.
