Abstract
The bogie comprises an axle (14) rotatably mounted on a fixed underframe, and measurement apparatus for measuring a physical magnitude related to rotation of the axle (14). The measurement apparatus (34) comprises a metal disk (36) secured to the axle (14) and provided with at least one mark-forming perforation (40), and a fixed detection assembly (50) for detecting the mark, which assembly comprises at least one inductive proximity detector (52). Preferably, the disk (26) is fixed to a collector ring (26) of a current return assembly (24) for transferring the current coming from a motor of the bogie to the axle (14).
Claims13
A rail vehicle bogie of the type comprising:
- a fixed underframe (12);
- at least one axle (14) rotatably mounted on the underframe (12);
- and
- measurement apparatus (34) for measuring a physical magnitude related to rotation of the axle (14), which measurement apparatus comprises a disk (36) secured to the axle (14) and provided with at least one mark-forming perforation (40), and a fixed detection assembly (50) for detecting the mark, which assembly is carried by the underframe;
- said bogie being characterized in that the disk (36) is made of metal, and in that the detection assembly (50) comprises at least one inductive proximity detector (52).
A bogie according to any preceding claim, characterized in that the perforation (40) is defined by two substantially radial surfaces (40A, 40B) that converge towards that face of the disk (36) which faces the detection assembly (50).
