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. The drive system is movable to and fro between two defined end positions. A vertically movable section of the track guide lever carrying the transverse guide member is coupled by way of an angle lever and a coupling rod with the expanding drive system. The expanding drive system is constructed so as to be reaction free or self-locking in the end position corresponding to the operating position of the transverse guide member and the expanding drive system or a roller feeler guide unit are provided with an automatic end position securing arrangement. |
