Claim 0:
1. A position-relative damper assist system (1) for use with a vehicle, the position-relative damper assist system (1) comprising:
top and bottom mounting components (5,3) cooperating with one another to define a corresponding stroke distance (7) between them, and being operable with respect to one another between compression and extension modes along said stroke distance, the top mounting component (5) being operatively connectable to a frame of the vehicle, and the bottom mounting component (3) being operatively connectable to a supporting component of the vehicle;
a piston assembly (9) being operatively disposed between the top and bottom mounting components (5,3), the piston assembly (9) having a piston head (11) being displaceable within a chamber (13) defined about a portion of one of the top and bottom mounting components (5,3), the piston head (11) being provided with at least one fluid passage (15) for allowing fluid (17) of the chamber (13) to travel from one side of the chamber (13) to another side of the chamber (13) via the piston head (11) of the piston assembly (9), in order to provide a corresponding damping effect;
an adjustment assembly (19) cooperating with the piston head (11) of the piston assembly (9) for adjustably varying an effective cross-sectional profile of the at least one fluid passage (15) in order to in turn vary a corresponding flow rate of fluid (17) passing through said at least one fluid passage (15), and in turn vary the resulting damping effect; and
a biasing assembly (21) cooperating with the adjustment assembly (19) for selectively varying a configuration of the adjustment assembly (19) in response to a given input indicative of the positioning of the piston assembly (9) within the stroke distance (7), in order in vary the resulting damping effect in response to a corresponding displacement-profile (23) provided by the biasing assembly (21);
wherein the piston assembly (9) comprises a piston rod (77) operatively extending between the bottom mounting component (3) of the position-relative damper assist system (1) and the piston head (11) of the piston assembly (9);
wherein the piston head (11) is removably mountable onto the piston rod (77);
wherein the piston head (11) is removably mountable onto the piston rod (77) via threading;
wherein the piston head (11) comprises a mounting collar (79) extending from a bottom surface (11b) of the piston head (11), the mounting collar (79) being configured for securing onto the piston rod (77);
wherein the piston rod (77) comprises a hollow section being provided an internal accumulator (49a) having a floating piston head (81); and
wherein the floating piston head (81) has a cross-sectional shape being complementary to that of an adjacent separator component (47), for allowing the floating piston head (81) to travel within a greater range for a same given length of the internal accumulator (49a).
