Abstract: A wheel truck for a steerable platform such as a skateboard. The wheel truck includes a base frame mounted below the platform and carrying a vertical support shaft and downwardly inclined steering shaft. An axletree upon which wheels are mounted is carried from the frame by resilient support means. The support means includes pairs of elastomeric bushings mounted about both of the support and steering shafts. The bushings are seated in sockets formed in the axletree for positioning the latter with respect to the frame. Fasteners are provided to secure the bushings on the shaft. The fasteners are adapted to change the steering response or to vary angular orientation of the axletree for purposes of changing the turning radius.

Abstract: A steering wheel mechanism in which independent front and rear steering is obtained by weight shifting. A pair of rocker members are pivotally mounted below the front and rear ends of a platform. A pair of spindles are pivotally mounted on king pins at opposite sides of each rocker member, and wheels are mounted on each of the spindles. Pitman arms are interconnected between mid-portions of each frame and steering arms which project from the spindles. Provision is made for changing steering response and for adjusting toe-in.
