US 4,071,256 A · Truck for skateboard or the like

Abstract

A skateboard truck having a cup-shaped housing with the axis thereof transverse to a mounting plate member secured adjacent the housing opening, the bottom of the housing having pivotally secured thereto a trunnion supporting a transversely extending axle and wheel assembly. An annular rubber cushion fits within the cup in alignment with the axis thereof, the inner surface of the cup and the cushion being matingly configured to restrain the cushion from rotating. A member is received within the cushion, the member having diametrically opposed outwardly extending flanges received within splits within the cushion, the member being secured for rotation with the trunnion whereby the surfaces of the flanges apply circumferential compressive forces to the adjacent surfaces of the cushion during pivoting of the triunnion. Means are provided for axially varying the volume or density of the cushion whereby to vary the circumferential compressive forces resulting from pivoting of the trunnion.

a generally cup-shaped housing having an open end and a bottom;
mounting means secured to said housing adjacent said open end, said mounting means extending in a plane transverse to the axis of said housing,
trunnion means rotatably secured to the bottom of said housing for rotation on said axis;
cushion means within said housing, said cushion means being circumferentially positioned about said axis;
and
other means within said housing coupled for rotation with said trunnion means, said other means having portions thereof engaging said cushion means whereby to apply circumferential compressive forces to parts of said cushion means upon pivoting of said trunnion means.
