Abstract:
A shock absorbing skateboard truck assembly comprising, in combination:an assembly base for attachment to the underside of a skateboard; a king pin projecting from said assembly base and having a threaded distal end; an axle support member defining an axle support member opening, said king pin projecting through said axle support member opening; first and second resilient pads encircling said king pin, said first and second resilient pads being spaced from one another and disposed at opposed sides of said axle support member; pad retention means retaining said first and second resilient pads in position relative to said axle support member; a king pin nut threadedly engaged with said king pin at the threaded distal end of said king pin; a resilient shock absorber member positioned between said first and second resilient pads and said assembly base and between said pad retention means and said assembly base, said resilient shock absorber member defining a hole receiving said king pin, rotation of said king pin nut on said king pin changing the compressive forces applied to said resilient shock absorber member; a double-ended bushing extending around said king pin and disposed within said first and second resilient pads, said bushing being axially slidably movable relative to said king pin selectively toward or away from said assembly base, said pad retention means including a flange radially extending outwardly from one of the ends of said bushing, said flange adjoining one of said resilient pads, the end of said bushing remote from said flange being a threaded end; and a bushing nut threadedly engaged with the threaded end of said bushing, rotation of said bushing nut on said bushing varying the compressive forces applied to said resilient first and second pads to change the steering characteristics of said truck assembly.
