Embodiment Construction

[0036] The terms "vertical" and "horizontal" are generally understood with respect to the usual orientation of a rail vehicle rolling on horizontal rails.

[0037] figure 1 The railroad vehicle 10 shown in includes at least one train car 12 .

[0038] Each train car 12 is associated with at least one truck 14 that supports the train car 12 .

[0039] Each railroad car 12 includes at least one interior compartment configured to accommodate passengers (passenger compartment) or cargo (cargo compartment).

[0040] For example, each bogie 14 is located at one end of an associated train car 12 and supports two adjacent train cars 12 when the railroad vehicle 10 includes multiple train cars 12, as figure 1 shown. Such a bogie 14 is said to be "common" for two adjacent train cars 12 .

[0041] According to conventional methods of construction, each railroad car 12 is supported at its respective ends by two bogies 14 .

[0042] The bogie 14 comprises at least one pair of wheels 1...

Abstract

The inventions concerns a derailment detection device (26) configured to be provided onboard a railway vehicle configured to move on rails (20) of a railway track (22).The derailment detection (26) device comprises: a magnetic assembly comprising at least one magnet and configured to be disposed faced to one of the rails (20); a sensor (30) configured to measure a magnetic force (F) between the rail (20) and the magnetic assembly; and an electronic processing module configured to compare the measured magnetic force to a predetermined threshold value and to emit an alert signal when the measured magnetic force is lower than the threshold value.

Description

technical field [0001] The present invention relates to a derailment detection device configured to be arranged on a railway vehicle for moving on a railway track. Background technique [0002] "Derailment" is understood as any situation in which at least one wheel of a railway vehicle is no longer in stable engagement with the corresponding guide rail. [0003] This includes full derailment, in which the wheels are completely disengaged from the guide rail, and partial derailment, in which the wheels are in an abnormal position relative to the guide rail while still in contact, which can lead to a complete derailment. [0004] Derailment of railway vehicles can cause serious material damage and even bodily harm to passengers and must therefore be detected quickly. [0005] However, a derailment at the rear of a rail car may not always be as apparent as at the head of the rail car where the driver would normally be. Consequently, significant damage may have been done even ...
