ABSTRACT:
An improved wheel carriage or truck assembly for skateboards and the like. The wheel carriage comprises a pivot arm which carries an axle and wheels near one end thereof. The opposite end is mounted to the bottom of the board for pivotal movement against a shock absorber in a vertical plane which includes the axis of the shock absorber. The pivot arm is mounted for pivotal movement about its axis for pivoting the wheels in a horizontal plane against the biasing action of the shock absorber. This arrangement provides excellent shock absorption, while the vertical and horizontal pivotal movement components provide enhanced turning and banking capabilities and thereby improve responsiveness.
In a preferred embodiment, the axis of the pivot arm and the shock absorber intersect at an angle of approximately 90.degree. to maximize shock absorption in the direction of motion. The angles at which the pivot arm and the shock absorber depend from the board can be varied to control turning and banking.
