  • Patent number: 8950336
    Abstract: Monorail vehicle that travels on a non-featured rail with substantial profile variation and controls roll attitude, lateral location, and loading through judicious placement of the vehicle's center of gravity without using springs or suspensions. The vehicle has a bogie for engaging the non-featured rail so the center of gravity has a lateral offset r1 from the rail centerline to produce a roll moment Nr determined by vehicle's mass and value of r1. The center of gravity also has a vertical offset r2. The bogie uses first and second assemblies for engaging the rail to produce a pair of surface normal reaction forces to thus control roll attitude and loading by the placement of the center of gravity, thereby enabling accurate alignment of the monorail vehicle.

The carrier can support a car through a platform having elements and chocks for locking contact with a front bumper and front wheels of the car Auxiliary wheels and rails cooperate to cause nearly all weight to be carried through the single main wheel. Traction is increased when necessary through application of increased upward forces to undersides of auxiliary rails and/or through developing magnetic forces between the steel wheel and steel rail. An AC induction motor is a main source of drive power. Acceleration and braking are assisted through epicyclic gearing, braking means and a DC motor/generator that is connected to a battery and that drives the carrier if supply of AC fails.

In the region of a curved element (12), the rail (6) has an elevation, with result that there is an increase there in the propulsion force which can be transmitted by a friction wheel (8) of the friction drive (7). An introduction aid (11) allows the guide roller (9) to be aligned without difficulty in relation to the rail (6). The industrial truck (1), rather than being bound to fixed cyclic operation by its friction drive (7), can be specifically accelerated or decelerated. In the event of malfunctioning of the industrial truck (1), the latter can easily be moved manually.

  • Patent number: 6338573
    Abstract: The present invention offers a universal guide device capable of using the sliders of conventional straight guide devices intact. The universal guide device does not need a different slider for each different radius of track rail. The universal guide device can be manufactured at lower cost than normal. This universal guide device in accordance with the invention comprises a track rail and sliders mounted to the rail via balls circulating through endless circular paths. The rail has at least one straight region and at least one curved region shaped in an arc with a given radius of curvature. Each of the sliders is of saddlelike cross section. The sliders span the rail. The sliders have ball-rolling surfaces shaped linearly. The curved region of the rail is set narrower than the straight region of the rail.

  • Patent number: 6178892
    Abstract: A transportation system uses a carrier conduit in the form of a long tube or channel in order to drive a vehicle by air pressure. A carrier having end plates obstructs the travel of air through the carrier conduit. Pressure differentials formed within the carrier conduit serve to propel the carrier through the carrier conduit. By rollably supporting the carrier within the carrier conduit, friction is reduced between the carrier conduit and the carrier. The carrier may be magnetically coupled to a vehicle having vanes and a set of track- or rail-engaging wheel assemblies on vanes. The vanes may pivot upon the vehicle and serve to allow the vehicle to rollably or slidably couple to the carrier conduit track. The motion of the carrier serves to propel the vehicle along the carrier conduit track as the vehicle is magnetically coupled to the carrier.

  • Patent number: 6036427
    Abstract: A vehicle transport system and accompanying guide device designed to serve in automated warehouses has a guide rail that guides the transport vehicle. The transport vehicle has a carrying platform. The vehicle runs along the rail astride it and linked by connecting guides. The guide rail is located beneath an upper surface of the carrying platform so that material carried thereon can be transferred across the rail to staging areas on the other side of the rail. By locating the vehicle astride the rail, the guide rail, which projects upwardly from the floor, does not interfere with access to the carrying platform. In an embodiment of the invention, the drive wheel of the vehicle is located at a longitudinal midpoint of the transport vehicle to minimize the parasitic effects on the guides connecting the vehicle to the rail generated by application of traction forces, applied by a drive wheel, to the side of the rail.

  • Patent number: 5934198
    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.

The fin (44) preferably is not a continuous or endless member, but extends several vehicle lengths in front of the vehicle (22) for steering and most preferably several vehicle lengths behind the vehicle (22) for propulsion and braking. A flexible traction belt (86) optionally can be coupled in tandem with the fin (44) to provide an endless loop propulsion system.

  • Patent number: 5575216
    Abstract: The linear motion rolling guide unit has a top seal secured to the casing which comprises a pair of lip seals that are in sliding contact with side areas of the upper surface of the track rail. The lip seals each have a pair of lip portions that incline from a base portion outwardly toward the sides of the casing. Because the lip portions are spaced a predetermined distance from each other, their sealing actions are not affected by each other, effectively preventing further ingress into the raceway grooves of foreign matters that have entered into the slider. When the pressure in the raceway grooves is increased by the supplied grease, the lip portion on the outer side is pressed with an increased force against the upper surface of the track rail, effectively preventing leakage of the grease.

  • Patent number: 5555814
    Abstract: An improved monorail-type track section for use in a material handling and sortation system in which one or more train-type trolleys or cars runs along the track between various sortation and handling stations. The track section comprises a substantially hollow, vertical support member terminating at an upper end in an upper transverse leg defining upper wheel bearing surfaces on each side of the support, and terminating at a base end in a transversely extending base leg defining lower wheel bearing surfaces on each side of the vertical support. The upper and lower wheel bearing surfaces are angled to trap upper and lower wheel assemblies on a trolley in a torsionally stable mounting arrangement. The spacing of the upper wheel bearing surfaces is less than that of the lower wheel bearing surfaces, such that removal of the upper wheel assemblies allows the entire trolley to be lifted vertically off the track section with clearance for the lower wheel assemblies.
