Truck apparatus for skate and skateboard devices including an elongated kingpin, means for affixing the upper end of the kingpin to the bottom of a load carrying platform at a selected angle and having a member disposed midway along the length of the kingpin and a friction surface and stop means, a wheel axle carriage assembly pivotally affixed to the lower end of the kingpin and adapted to rotate about the axis of the kingpin and having a second friction surface and stop lugs, a resilient drag sleeve and turn restoring element compressively disposed between the first and second friction surfaces, and a lock nut for selectively urging the carriage assembly toward the mid-portioned member so as to compress the drag sleeve between the first and second friction surfaces with a predetermined compression force such that the carriage assembly may be resistively and partially resiliently rotated about the axis of the kingpin within a range determined by the interaction of the stop lugs and the stop means and with a degree of freedom determined by the compression of the drag sleeve.

Truck apparatus for skate and skateboard apparatus comprising: an elongated kingpin means; means for affixing one end of said kingpin means to the bottom of a load-carrying platform at a selected angle and including a member disposed midway along the length of said kingpin and having means forming a first friction surface and stop means; wheel axle carriage means pivotally affixed to the other end of said kingpin means and adapted to rotate about the axis of said kingpin means, said carriage means having means forming a second friction surface and lug means adapted to engage said stop means when said carriage means is rotated a predetermined angle in either direction about said axis; resilient drag sleeve and turn restoring means disposed between and in frictional engagement with said first and second friction surfaces; and means for urging said carriage means toward said member so as to compress said resilient means between said first and second surfaces with a selected compression force such that said carriage means may be resistively and partially resiliently rotated about said axis within an angular range determined by the interaction of said stop means and said lug means and with a degree of freedom to turn determined by the compression of said resilient means.
