Abstract: A skateboard truck configured to be mounted to a skateboard deck, with a hanger with a wheel axle configured to hold skateboard truck wheels; a suspension system with a flex member configured to attach the hanger resiliently to a skateboard deck; a rolling contact bearing connecting the hanger with the flex member such that the rolling contact bearing allows rotation of the hanger with respect to the flex member by a steering angle around a steering axis extending substantially vertically to the wheel axle; and a spring mechanism attached to or integrally formed with the flex member biasing the hanger to the neutral position where the steering angle is zero.

Abstract: The present invention relates generally to skateboard and caster devices. More particularly, in a manner the invention concerns both dual wheel and single wheel axle supports of trucks and casters having a suspension mechanism for absorbing shock. The suspension mechanism is uniquely designed to progressively increase suspension resistance as forces acting on the mechanism increase by elastically deforming an independent arm in a manner to contact another arm or structure thereby transforming the independent arm into a dependent arm that results in a progressive resistance to a load until the forces are terminally engaged into a resilient abutment. A novel alignment mechanism functions to maintain the skateboard steering function.
