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.

A wheel truck for a steerable platform with a base frame carried by the platform, including the combination of an axeltree for mounting wheel means for rotation, first support means for resiliently mounting a first portion of the axeltree on the platform, said first support means including a first shaft mounted on and extending vertically from the frame together with first elastomeric bushing means mounted about the shaft, second support means for resiliently mounting a second portion of the axeltree on the platform, said second support means including a second shaft carried by the frame and inclining downwardly at an angle with respect to the first shaft together with second elastomeric bushing means mounted about the second shaft, said second support means permitting pivotal movement of the axeltree relative to the platform about an axis inclined at an angle from vertical whereby movement of the axeltree about the inclined axis relative to the platform creates a steering action as the platform is rolled on the wheel means over a surface, said first and second support means providing the sole direct connection between the base frame and axeltree, and fastener means for locking the second elastomeric bushing means under a selected compressive force whereby steering responsiveness of the wheel truck can be selectively varied.
