  • Patent number: 7185407
    Abstract: A rail system for positioning a toolhead above a workpiece uses a rack cut into one edge of the rail and driven by a pinion gear whose shaft is approximately perpendicular to a workpiece to couple the rail to the toolhead. Multiple rollers placed on the toolhead allow contact between the toolhead and the rail to be effectively continuous despite the cutting away of as much as or more than two-thirds of the rail edge to provide rack teeth. Separating thickness axis containment from transverse with a square rail edge and separate thickness axis and transverse rollers allows the toolhead to follow a rail as the rail flexes over a curved surface with minimal position error. Several variations in rail, bearing, and rack implementation can realize comparable results.

  • Patent number: 6523481
    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.

    Abstract: A personal rapid transit vehicle for movement on a monorail guideway system advantageously limits the vehicle width by requiring the riders to be seated in the vehicle. Furthermore, a suspension system for coupling the vehicle to the guideway provides for a very light, narrow driverless vehicle in which the riders face sideways and are suspended laterally from and seated over the guideway. The suspension system controls lift, slip and roll of the vehicle relative to the guideway and allows a reduction in the guideway cross-sectional area. Moreover, the guideway, rather than the vehicle itself, absorbs all overturning or roll vibration.

  • Patent number: 4301739
    Abstract: A vehicle adapted to be externally guided mechanically along guide tracks, especially for public local passenger service, which includes a steerable vehicle axle provided with steerable wheels and with maximally bending resistance supporting arms arranged at wheel hubs of the steerable wheels and extending unilaterally forwardly in the driving direction of the vehicle. A transverse guide arrangement is disposed at the forward ends of the supporting arms so as to provide for an automatic track-side influencing of the turning angle of the steerable wheels. A motor is fixedly mounted in a zone of a hub of a steering wheel so as to be capable of operatively acting upon the steering wheel. The motor, when an output part thereof is at a quasi-stand still, is capable of exerting a torque on the steering wheel which torque can be freely selected in its effective direction.

  • Patent number: 4274338
    Abstract: A guided vehicle having a body with rubber-tired steerable running wheels mounted on axles. A suspension system for the axles includes transversely extending upper and lower link arms which are parallel with each other and have equal arm lengths. Each of the links or link arms has one end connected with the wheel axle through a joint mechanism for a steering movement and a rotative movement about a longitudinal axis and its other end connected at two longitudinally spaced portions with the vehicle body for rotative movement about a second longitudinal axis. Air springs are disposed between one of the links and the vehicle body for normally maintaining the links substantially horizontally to thereby maintain the associated wheel always vertical.

    Abstract: A guided vehicle including at each end portion of the body a pair of steerable running wheels adapted to run on track surfaces and a pair of guide wheels adapted to run along guide rails provided at the opposite sides of the track surfaces. A steering linkage is provided for connecting the running and guide wheels so that the former is steered in response to a transverse movement of the latter. A friction type restraining device is provided in the linkage so that the steering movement is not produced by a small amount of surface roughness in the guide rail.

  • Patent number: 4223611
    Abstract: A spring biased over-center linkage transmits a biasing force to opposite guide wheels in alternate sequence for maintaining a selected one of the guide wheels in contact with one of two parallel guide surfaces, depending upon whether the vehicle is operative in a left or a right follower mode. A steering assembly controls the direction of travel of the vehicle in response to the position of the selected one guide wheel as it follows the contour of the cooperative guide surface. A double-acting reciprocative operator positions the over-center linkage at left and right bias positions for left and right follower mode operation, respectively. A spring provides over-center bias to the over-center linkage and constitutes the sole source of biasing force. The apparatus is suitable for use with a vehicle in an automated transportation system in which the vehicle travels along a predetermined travel path or a guideway.

  • Patent number: 4207821
    Abstract: An overhead monorail conveyor whose inverted U-shaped rail has flanges provided with inwardly extending lower marginal portions to provide tracks for the wheels of a vehicle having an inverted U-shaped frame which surrounds a portion of the rail. The wheels are mounted on brackets which extend at a level below the marginal portions of the flanges and thereupon upwardly into the interior of the vehicle frame. The motor which drives the vehicle is mounted in the frame in the interior of the rail, the same as the conductors which supply electrical energy and the toothed rack or racks which mate with several gears driven by the motor. The interior of the rail further confines and shields other sensitive components of the conveyor, such as electric switches, proximity detectors, contacts which slide along bus bars, centering rolls for the frame of the vehicle, and devices for biasing the motor-driven gears against the toothed racks.
