  • Patent number: 10858788
    Abstract: A monorail switch for a monorail guideway comprises a moveable guide beam having lateral running surfaces and an actuating mechanism. The actuating mechanism, equipped with a counterweight, is operative to move the moveable guide beam from a tangent position, where the moveable guide beam is aligned with a tangent travelling direction, to a turnout position, where the moveable guide beam is aligned with a diverting direction. Potential energy stored in the counterweight is released and at least partially stored in the form of elastic potential energy in the lateral running surfaces when the moveable guide beam is moved from the tangent position to the turnout position. Similarly, the elastic potential energy stored in the lateral running surfaces is released and at least partially stored in the form of potential energy by the counterweight when the moveable guide beam is moved from the turnout position to the tangent position.

  • Patent number: 10855145
    Abstract: An electric machine with a rotor (4) rotatably disposed within a stator (1) with a stator winding (3) has a plurality of permanent magnets (8) received therein. A casing (17) encloses the stator and the rotor, and an impeller (13) with blades is fixed to an axle (7) of the rotor so as to generate a flow of air through the casing for cooling end-turns (25) of the stator winding by drawing air through an inlet opening (18) at one end of the casing and blowing it out of the casing through an outlet opening (19) at the other end of the casing. At least one shutter is arranged to close the outlet opening (19) when the temperature of the cooling air through the outlet opening reaches a predetermined level well above a maximum level of the temperature possible to be reached under normal operation of the electric machine so as to close the outlet opening upon occurrence of arcing in the end-turns. A temperature dependent member is arranged in the air flow through the outlet opening to obtain such closing.

  • Patent number: 10807617
    Abstract: A retaining system for a mass-transit vehicle adapted to travel on a guideway includes a longitudinal retaining track having two retaining rails. Each retaining rail has a projection projecting inwardly toward the other retaining rail. A grabbing mechanism of the mass-transit vehicle has grabbing portions extending outwardly underneath the projections of the retaining rails. The grabbing portions are pivotally and resiliently connected to a wheelset of the mass-transit vehicle proximate a midplane of the body. When the mass-transit vehicle rolls on one side past a predetermined angle, an opposite one of the grabbing portions is operative to contact a corresponding one of the horizontal projections. The roll of the mass-transit vehicle is thereby gradually stopped under a force developed by a corresponding resilient element.

  • Patent number: 10725447
    Abstract: An automated method for straightening/correcting deformations made to panels when welded to metallic structural components is disclosed. In the train industry, when an aluminum component, such as a vehicle's exterior shell, is welded to hidden structural parts, deformations thereon may occur. Such deformations need to be subsequently corrected, and the present method uses robots and optical measuring of the deformed surfaces to conduct a straightening thereof. The method includes four main steps. First, the deformed surface is scanned with an optical sensor to make physical measures/characterizations thereof. Second, the gathered data are compared with the desired resultant by a software. Third, once the comparison is done, the software performs an analysis to select the proper parameters to be used in the straightening method that will be applied at each area requiring straightening. Finally, a robot executes the operations specified by the software to perform the straightening process.
