Wheel suspension for skateboard (rigid-axle version)

摘要

The invention relates to a skateboard which is steered via the feet by weight displacement. In order that the wheels, inter alia to make possible high speeds, have a constantly good running-surface contact (and thus also allow use on uneven running surfaces), the axles are guided in a sprung manner in relation to the board superstructure. What is novel in relation to previously known sprung rigid-axle wheel suspensions in skateboards is the wheel guidance by means of links, which leaves 2 degrees of freedom open to the rigid axle 2: a vertical movement of the axle body for compression and extension and also a rotary movement approximately about its vertical axis for steering the skateboard. To this end, the links are arranged obliquely in side view in such a manner that - they rotate about a horizontal transverse axis during compression and extension in the same direction (straight travel) (and thus the axle bodies therefore spring with them in parallel) and - during compression and extension in opposite directions (curve travel), their projected lengths differ clearly on the inside of the curve from the outside of the curve in plan view, so that the axle bodies describe a steering angle. <IMAGE>
