Guide Rollers Patents (Class 104/245)
  • Patent number: 8881657
    Abstract: A method and device lock a guiding system of a vehicle guided by at least one rail. The locking device includes first and second cylinders combined with guiding devices belonging to the guiding system of a steering axle. Each of the cylinders contains at least two characteristic configuration states: a first configuration state placing the guiding device with which the cylinder is combined in a first guiding state, and a second configuration state placing the guiding device with which the cylinder is combined in a second guiding state. A power supply supplies power to the cylinders to switch the configuration state. The power supply is coupled with a rotary member, the rotation of which is mechanically linked to the movement of the vehicle, such that a change in the direction of rotation of the rotary member is transmitted to the power supply and switches the configuration state of the cylinders.

    Abstract: At one end in a running direction of a bogie, two guiding wheels are arranged, and at another end in the running direction of the bogie, two stabilizing wheels are arranged. The stabilizing wheels are positioned at a level lower than that of the guiding wheels. The stabilizing wheels function to guide the bogie along the monorail and prevent the bogie from falling off the track. With this arrangement, the total number of guiding wheels and stabilizing wheels can be reduced, and particularly, the number of the guiding wheels can be reduced. Accordingly, the bogie can be manufactured with a low cost. A traction link for connecting the bogie and the car body is arranged on one end of the bogie, and, accordingly the length of the bogie can be shortened.

The axially supported wheels may be mutually pivotable about a transaxial shaft and controlled by an angle control member hinged to the actuator. Through the angle control member the actuator can automatically control the transaxial pivoting and angle of the wheels as well as the tilt of the angle control member during raising and lowering operations of the guide arm. The guide arm is useful for automatically steering public transportation vehicles.

  • Patent number: 5291834
    Abstract: In magnetic levitation vehicles, supporting and driving forces are generated by a long stator on the track and permanent magnets on the vehicle. The underside of a rail provides the attachment of the long stator; the rail further has two oppositely disposed horizontal running surfaces for pairs of spacer rollers on the vehicle and a vertical running surface for lateral guide rollers on the vehicle. For a particularly simple and inexpensive production of the rail it is proposed to make the one end section of the railhead of the rail the horizontal running surfaces and a lateral guide profile fastened to the underside of the railhead the vertical running surface.

  • Patent number: 5245930
    Abstract: An emergency life saving vehicle (ELSV) for providing emergency services on a bridge independently of traffic conditions thereon. In particular, the ELSV conforms to the particular configuration of a bridge so as to ride along an otherwise unused portion of the bridge, and thereby circumvent any traffic which may have accumulated on the bridge. There are at least three different embodiments of the ELSV, each embodiment corresponding to a particular bridge structure. A first embodiment has a raised center portion so that the ELSV is able to straddle a lane dividing wall on a single span bridge; a second embodiment is adapted to straddle a space between two adjacent and parallel spans of a two span bridge by simultaneously riding on the interior walkways of each span; and a third embodiment rides along the interior walkways and retaining walls of a two span bridge.

  • Patent number: 5115746
    Abstract: A transverse guide roller for track-guidable buses effectively prevents the access water to the rotational bearing of such rollers housed rotatably in a horizontal plane. To this end, the rotational bearing is accommodated in a bearing bell which covers the rolling bearing arrangement in a protective and sealing manner. The wheel body has essentially the shape of a cup with an upwardly pointing opening and with a bearing journal projecting from the cup bottom. The rolling bearing is fixed on the bearing journal with the inner ring as a rotating rolling bearing ring. The cup bottom has, at its lowest point, several discharge orifices for the unhindered discharge of water which may have penetrated.

  • Patent number: 5114073
    Abstract: A laterally stable and self-turning wheel and rail assembly. The curved rolling surfaces of the wheels bear against curved contact surfaces of the rails such that centrifugal force causes lateral translation of the wheels on the rails, thereby increasing the effective rolling radius of an outside rail while decreasing or maintaining the same effective rolling radius of an inner wheel. The altered rolling radius causes the wheels to move along a curved path without slipping or sliding. Flanges are provided adjacent track turnouts so that guide members activated by a vehicle operator may contact the flanges to either maintain the vehicle in the same set of tracks, or switch the vehicle through the turnout onto a new section of track.
