ABSTRACT:
An apparatus for varying the damping characteristics of a shock absorber of the kind comprising a piston rod and an adjusting shaft mounted coaxially within the piston rod for rotation relative to the piston rod. Upon a change in its angular position relative to the piston rod, the adjusting shaft effects a change in an effective oil passage area in the shock absorber, and thus varies its damping characteristics. The adjusting shaft (16) has a free end (15) located at the end of the piston rod. The apparatus comprises a housing (4, 18, 19, 50) arranged to be attached to the end of the piston rod. The housing accommodates, in succession: an electric motor (1) adapted to be driven and positioned in two directions; a speed reducer (2) coupled to an output shaft (26) thereof; and a universal joint (3) disposed between an output member (33) of the speed reducer (2) and the free end (15) of the shock absorber adjusting shaft (16).
