ABSTRACT:
An improved skateboard truck is disclosed which incorporates exceptionally rapid and consistently accurate axle rebound to the straight-ahead position, consistent and predictable steering response, an improved balance between stability and maneuverability, fine steering control, and a wide range of steering radii. A yoke containing the truck's axle includes a central body portion with a central aperture therein for a pivot pin. Sockets for containing the ends of coil springs are formed in the yoke on either side of the yoke's central aperture. A baseplate includes a second aperture for receiving the end of the pivot pin, and the pivot pin itself extends through the yoke into the baseplate. Second sockets for receiving the other ends of the coil springs are also formed in the baseplate on either side of the second aperture, and the coil springs themselves extend from the sockets in the yoke to the sockets in the baseplate. The sockets are conically shaped. As the yoke turns, pivoting the wheels on the outer ends of the yoke in a very fixed arc about the pivot pin, the coil springs remain substantially columnar and unbuckling as they pivot at each of their ends in the sockets' bases.
