Abstract:
A system for monitoring a pantograph of a railway vehicle, the pantograph being adapted to be connected to a catenary and electrically connected to a traction unit, the catenary being adapted to provide an alternating current to the railway vehicle, the system further including: a voltage step detection device for detecting a voltage step of a pantograph voltage at the pantograph, a zero crossing detection device for detecting a zero crossing of a line current, the line current being a portion of a pantograph current provided to the traction unit, the pantograph current being the current flowing through the pantograph; and a bouncing detection portion adapted to determine at least one bouncing time of the pantograph based on one or more detected voltage steps of the voltage step detection device and/or one or more detected zero crossings of the zero crossing detection device.
Abstract:
The railway vehicle includes two adjacent carriages (6), each including a carriage body (8), the bodies (8) being supported by a common bogie (1) and being articulated with each other with an articulation device (2). The articulation device (2) is received in a space (30) of the bogie (1), the space (30) being delimited along a longitudinal direction by a first abutment surface and by a second abutment surface (34), the articulation device (2) extending facing the first and second abutment surfaces (34) so that, when the railway vehicle moves in a first longitudinal direction, the first abutment surface comes into contact with the articulation device (2), and, when the railway vehicle moves in a second longitudinal direction, the second abutment surface (34) comes into contact with the articulation device (2).
Abstract:
This system for powering an overhead contact line, which includes a contact wire consisting of a plurality of conductive sections separated by insulating sections, includes power supply sub-stations, each conductive section being connected, on the side of an upstream end, to an upstream sub-station via an upstream controlled switch and, on the side of a downstream end, to a downstream sub-station via a downstream controlled switch. This system includes a detection device, associated with a conductive section, to be monitored, which includes a means for transmitting a characteristic signal to an upstream or downstream end of said conductive section and a receiving means able to receive the characteristic signal at the other end, the receiving means modifying the value of a state signal applied to a control circuit for actuating the opening of the downstream switch and/or of the upstream switch.
Abstract:
The table (10) includes a plate (12) extending, in a longitudinal direction, between a first lateral edge (12A) bearing first removable attachment elements (14) to a lateral wall of the compartment, and a second free lateral edge (12B), and a central leg (18) extending between a first end (18A) connected to the plate and a second end (18B) including second removable attachment elements (20) to the floor of the compartment. The first end of the central leg is connected to the plate through a pivot connection (26) allowing pivoting of the central leg for folding it back towards one of the first or second lateral edges of the plate, and the plate includes, at the other one of the first or second lateral edges of the plate, at least one supporting member (28) on which the plate is intended to be supported when the plate is laid on the floor.
Abstract:
A signaling system and method provide a first lamp assembly including one or more light generating devices configured to activate to inform an operator of a vehicle system of information related to movement of the vehicle system. The first lamp assembly includes processing circuitry configured to control and monitor operation of the one or more light generating devices. A wayside station is configured to be communicatively coupled with the first lamp assembly by a single conductive communication pathway. The wayside station is configured to conduct electric current to power the first lamp assembly and to communicate with the processing circuitry of the first lamp assembly via the single conductive communication pathway.
Abstract:
The gap filling device includes a movable ramp that is movable in a horizontal direction between a retracted position within a housing arranged under a floor of the rail vehicle, and a deployed position extending out of the housing. The ramp further has an upper surface that is accessible in the deployed position. The ramp includes lateral flanged edges extending over at least a portion of the length of the ramp, with each being movable between a first position, in which this lateral flanged edge extends vertically projecting outwards in relation to the upper surface of the ramp up to a first height, and a second position, in which the lateral flanged edge extends up to a second height that is lower than the first height.
Abstract:
A protection system of a railway vehicle traction system includes an electric motor and an electrical power supply circuit. The system further includes: a mechanical coupler between first and second components of a transmission line, the first component being connected to an output shaft of the electric motor and the second component being connected to an input shaft of an axle of the railway vehicle, the coupler being able to be in an engaged or disengaged state; and a controller able to apply a disengagement signal to the coupling signal, to switch from the engaged state to the disengaged state if a failure of the power supply circuit and/or the electric motor is detected.
Abstract:
A system includes a converter for powering a synchronous electric machine to which it is connected by cables, an insulating device and a mechanism for short-circuiting phases of the machine. The system includes primary detectors for detecting an overcurrent in the converter and a securing device able to open the insulating device when receiving a primary detection signal emitted by the primary detector. The system also includes secondary detectors able to detect a short-circuit downstream from the insulating device and to emit a secondary detection signal toward the securing device, the latter actuating the closing of the mechanism for short-circuiting as long as they have already received a primary detection signal having led to the opening of the insulating device.
Abstract:
A system includes an onboard device and a ground device. The onboard device incorporates a geolocation device, a plurality of sensors and at least one shaping module for the raw measurement signals delivered by one or more of said sensors to generate at least one formatted signal. The ground device incorporates a computer able to analyze said at least one formatted signal, to generate at least one indicator relative to the track and/or the rolling stock, said indicator making it possible to detect damage and monitor its variations so as to optimize maintenance of the track and/or rolling stock. The computer is a damage module able to compute said damage indicator from said at least one formatted signal and a model of the monitored damage type.
Abstract:
A compressible filler piece for a brake calliper of a railway vehicle is adapted to at least partially fill out a space needed by a component (409) of the brake calliper for its operation. The filler piece can be applied to the protection of wheel brakes of low floor passenger trains against ice and snow.
