摘要： This electric switching device (2) comprises a first module (4), including a first support (42) on which a circuit breaker (44) is mounted, and at least one second module (6), including a second support (62) on which an electric component (64) is mounted that is able to be associated with the circuit breaker. In particular in order to facilitate the maintenance of this switching device, the latter includes guiding means (81 and 82) that are able to guide the first and second supports relative to one another between a disassembled configuration, in which at least one of the first and second modules is disengageable from the guiding means independently of the other, and an assembled configuration, in which the circuit breaker and the electric component are in a relative connection position and are able to be electrically connected to or disconnected from one another.

摘要： A brake disc assembly includes a central drive hub and a wear disc, which includes first and second faces held together axially about the hub. Each face has a respective inner surface and is formed of at least two distinct segments. Each segment extends between two radial edges. The radial edges of the segments of one face do not extend opposite the radial edges of the segments of the other face. Each segment of the face is adapted to be secured to a segment of the other face via at least one fastening member adapted to hold said faces.

摘要： A control device is for at least two traction engines of a railway vehicle. The control device includes an estimation module configured to estimate a traction power requirement of the rail vehicle as a function of at least one position signal of the rail vehicle, a determination module configured to determine a required operating state of each engine based on the power requirement, an adaptation module configured to determine, from the required operating state of each engine, an adapted operating state of said engine as a function of at least one specific parameter relating to the operation of the rail vehicle, and an emission module configured to emit a control signal to each engine.

摘要： The invention relates to a vehicle comprising a driver's cab (12) comprising a base (14) and a seat (16), the vehicle having a longitudinal direction (X).
The base (14) has a center (20) and a central longitudinal plane (P), the central longitudinal plane (P) extending in the longitudinal direction (X) and passing through the center (20) of the base (14). A projection of the seat (16) in an elevation direction (Z) on the base (14) is comprised in the base (14).
An assembly comprising the base (14) and the seat (16) is designed to rotate with respect to a body of the vehicle about a first axis (D), the first axis (D) extending in an elevation direction (Z). The first axis (D) passes through the center (20) of the base (14).-

摘要： Disclosed is a method for determining the relationship between a track-circuit current signal and a railway vehicle location, including: sending, by a track circuit, current signal across a railway track block; measuring the current signal for different railway vehicles running successively on the railway track block; aligning the measured current signals and calculating a reference curve as the average value of all the aligned curves by using a Dynamic Time Warping algorithm, this reference curve representing the relationship between the track-circuit current signal and the railway vehicle location on the railway track block.

摘要： A method controls the height of a floor of a car of a vehicle relative to a platform. The car includes a body provided with a distance sensor, at least one bogie and at least one secondary suspension between the bogie and the body. The method includes measuring the distance between the distance sensor and the platform via the distance sensor, calculating the difference between the height of the platform and the height of the floor from the measured distance, and adjusting the height of the secondary suspension based on the difference.

摘要： A computer implemented method is for determining railway vehicle movement profile type of a railway vehicle movement profile. The railway vehicle movement profile includes a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time. The method includes obtaining a railway vehicle movement profile, normalizing the railway vehicle movement profile, extracting one or more features from the normalized railway vehicle movement profile, determining the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process, and assigning the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid

摘要： A method is for determining a status of a track section of a railroad. Each end of the track section is connected to a respective detector. One of the two detectors transmits a current along the rails of the track section towards the other detector and receives a current transmitted along the rails of the track section from the other detector. The track section is further equipped with a computer in communication with the two detectors. The computer calculates an instant value of the status of the track section as a function of an instant vector based on a measure of an intensity of the current transmitted by a first of the detectors as measured by the first detector (Txl1), a measure of an intensity of the current received by the first detector as measured by the first detector (Rxl1) and a measure of an intensity of the current transmitted by the second detector as measured by the second detector (Txl2).

摘要： The invention relates to a railway vehicle comprising a car (14) and a bogie (16). The bogie (14) comprises a chassis (28) and a secondary suspension system (30). The secondary suspension system (30) comprises: a set (34) of springs; a jack (36) comprising two ends (44, 46); and a supply device (38) of the jack (36). The jack (36) is configured to go from a first so-called retracted configuration in which the jack (36) is only connected to the car (14) by the first end (44) to a second so-called deployed configuration in which the jack (36) is also connected to the chassis (18) by the second end (16).
The power supply device (38) is configured, in the deployed configuration, to supply the jack (36) so as to move the car (14) away from the chassis (28) or to keep the distance between the car (14) and the chassis (28) constant.-

摘要： A measurement process, intended for measuring at least one wheel of a train, including an acquisition step, during which a plurality of profiles of at least a part of the wheel are acquired by plurality of optical sensors, as the train moves in front of the optical sensors, a mapping step, during which, for each optical sensor, the profiles acquired by the optical sensor are joined by a control module, to obtain a map of the part of the wheel further transformed into a cloud of points, a rejoining step, during which the clouds of points obtained from the optical sensors are joined to form a three-dimensional image of the wheel, and an analysis step, during which a plurality of reference points and reference distances are measured on the three-dimensional image.
