1453542 Railway vehicle undercarriages AUTOMATISK DOSERINGS KOMPENSATOR AB 3 Dec 1974 52275/74 Heading B7L To reduce lateral movements of a railway vehicle caused by irregularities in track 12, each wheel 1 is mounted for rotation about a substantially vertical axis 11, such rotation being initiated when track irregularities are detected by sensors 18 or by indicators 14 which are responsive to lateral movement of a wheel relative to the vehicle body. Each wheel is supported by a bearing box 2 to which is pivotally attached one end of an arm 7. The arm 7 is supported at its other end on a bearing 6 carried by frame 5 and is rotatable about axis 8 in direction 9, within limits defined by elements 10 which embrace the arm and contain indicator 14. Sensing means 14 or 18 transmits a signal to an hydraulic or pneumatic control means 50 which retracts or extends a pistonrod 16 to effect compensating rotation of the wheel 1 in direction 17. The wheel may also have a preset toe-in angle. A pair of the wheels may be mounted to a frame supporting either the mid-length of a single vehicle body or the ends of two adjacent vehicle bodies. An alternative embodiment in which a single wheel is mounted directly on a vehicle body is also described, Fig. 4 (not shown).
