Abstract: A motor vehicle which may be utilized in a track or rail bound conveyance or on a normal roadway, with the vehicle including steerable supporting wheels and at least one transverse guide member arranged between opposite steerable supporting wheels on a horizontally pivotable track guide lever. The transverse guide member acts on the steerable supporting wheels and extends, in an operating position, below a tread level of the supporting wheels and, by way of a horizontal swivel joint in the track guide lever, can automatically be retracted from the operating position into an ineffective or waiting position and/or lowered into an operating position by roadway responsible roller feelers or the like movably guided at right angles to the driving direction. An expanding drive or force transmission system is coupled with the roller feeler with the system producing, upon a roller feeler movement, a movement oriented in a longitudinal direction of the vehicle.
