the current disclosure as top hanger 18 rotates in a counter clockwise direction top ring gear 26 rotates in a clockwise direction fig8 is a cut away view of the gearing assembly of a skateboard truck showing directions of rotation of a top ring gear and a planet gear according to selected embodiments of the current disclosure as top ring gear 34 rotates in a clockwise direction planet gear 32 rotates in a clockwise direction fig9 is a cut away view of the gearing assembly of a skateboard truck showing a rotated planet gear and corresponding moon gears according to selected embodiments of the current disclosure as planet gear 32 rotates in a clockwise direction moon gears 36 a and 36 b rotate in a counter clockwise direction fig1 is a cut away view of the gearing assembly of a skateboard truck showing rotated moon gears and rotational movement of a rivet according to selected embodiments of the current disclosure as moon gears 36 a and 36 b rotate in a counter clockwise direction sun gear 28 rotates in a clockwise direction since the caster wheel via the caster bracket and rivet 34 is connected to the sun gear 28 it moves in a similar direction thus when top ring gear 26 rotates in a clockwise direction so does the caster it must be appreciated that the same events occur with the bottom hanger as they do with the top hanger but in reverse thus when the bottom ring gear rotates counter clockwise so does the caster however while each hanger may cause the caster to move in a particular direction the gearing.
