摘要:
The performance of a passive-levitation vehicle is improved for moving over a path, wherein the vehicle has a levitation skid slidable on the path and capable of developing a levitation force to support a compartment at a certain distance from the path. For this aim, there is a suspension, connected between the compartment and the skid, comprising a kinematic structure to confer degrees of freedom and relative constraints between the skid and the compartment; a passive elastic element connected between the skid and the compartment; and a controlled- dynamic element able to exert a force having controlled dynamics between the skid and the compartment; wherein the passive elastic element and the controlled- dynamic element being mounted in parallel to each other and connected, e.g. at their ends, respectively to the skid and the compartment. By means of a sensor the distance is detected between the skid and the path, and an electronic circuit, connected to the sensor and to the controlled- dynamics element, carries out a feedback control in order to adjust said distance.

A transportation system is disclosed that includes a monorail (100) along a column-supported rail (113) and a movable weight system (510) that repositions and/or accelerates a movable weight (550) along its rail to counterbalance a moment associated with weight and/or a centrifugal force of monorail relative to the column (222). Also disclosed is a linear induction motor (400, LIM) system that enables LIM to tilt and thereby remain close to rail, which mitigates potential thrust losses and/or air losses. Further disclosed is an air bearing system (300) where the air bearing (325) has compliance and resilience that minimizes air loss between the rail and the bearing. Additionally disclosed is a rotatable wedge system (1000) that essentially expands and/or contracts automatically to maintain an adjacency between two rail portions. Further still, disclosed are embodiments where LIM's attachment to assembly provides assistance to lessen air pressure needed for air bearing.
摘要:
A track-guided transport vehicle (1) for transporting big loads along a track contains a synchronous linear drive provided with a long stator (5) that extends along the track and an exciter winding arranged on the vehicle. The long stator (5) generates a field of travelling waves that cooperates with a static magnetic field generated by an exciter winding (E) on the vehicle so as to move it forward. In order to supply electric drive energy to the compressor unit (8) that generates the compressed air required for air cushions (3, 3'), a higher frequency alternative current is superimposed on the current supplied to the windings along the track, said alternative current being coupled by a transformer to the winding on the vehicle. There the energy can be decoupled by means of a rectifier and be made available for feeding the electromotor of the compressor unit (8).

Un véhicule guidé (1) de transport de grosses charges le long d'un trajet contient un entraînement linéaire synchrone pourvu d'un stator allongé (5) situé le long du trajet de déplacement et un enroulement excitateur monté sur le véhicule. Le stator allongé (5) génère un champ d'ondes progressives qui coopère avec un champ magnétique statique généré par un enroulement excitateur (E) sur le véhicule afin de propulser le véhicule. Afin de fournir l'énergie électrique d'entraînement à l'unité de compression (8) qui génère l'air comprimé pour les coussins pneumatiques (3, 3'), un courant alternatif de plus haute fréquence est superposé au courant fourni aux enroulements situés le long du trajet, ce courant alternatif étant couplé par un transformateur à l'enroulement situé sur le véhicule, où l'énergie peut être découplée au moyen d'un redresseur de courant et être mise à disposition pour alimenter le moteur électrique de l'unité de compression (8).
摘要:
This invention relates to the use of a compliant load bearing shoe 74 on a transportation vehicle 64 designed to move either people or goods. The shoe 74 is designed to support a load on a cushion 96 of pressurized fluid between the shoe 74 and a track 60, where either the shoe 74 of the track 60 is adapted to inject fluid under pressure therebetween. The shoe and the track have co-operating lower and upper surfaces 73, 78 respectively, which act in concert when the shoe 74 is in use. The surface of the shoe 74 has side edge regions 90, and an intermediate region 93. Pressurized fluid is injected between the shoe and the track and the lower surface 78 of the shoe deflects so a plenum is formed between the shoe and the track. A partial seal is formed at the side edge regions 90 between the surface of the shoe and the track to limit the escape of the pressurized fluid from the plenum.
