Patent

CA 2729609

The invention relates to a measurement bearing, in particular for a wheel set of a rail vehicle, having a rotational axle and at least one first bearing ring (103), wherein the first bearing ring (103) defines a main supporting direction and a circumferential direction extending transversely with respect to the main supporting direction, and the first bearing ring (103; 203) is designed to take up bearing forces which have at least one force component in the main supporting direction, and during operation said bearing forces are applied to the first bearing ring (103) via a plurality of rolling bodies (104). The first bearing ring (103) has at least one first recess (105) in which a sensor device (110) is arranged, wherein the sensor device (110) is designed to sense a sensing variable which represents the bearing forces which are applied to the first bearing ring (103).

Linvention concerne un palier de mesure, notamment pour une paire de roues dun véhicule ferroviaire, comprenant un axe rotatif et au moins une première bague de palier (103). Selon linvention, la première bague de palier (103) définit une direction dappui principale et une direction périphérique qui sétend transversalement par rapport à la direction dappui principale et la première bague de palier (103 ; 203) est configurée pour absorber les forces porteuses qui présentent au moins une composante de force dans la direction dappui principale et qui, en fonctionnement, sont induites dans la première bague de palier (103) par le biais dune pluralité déléments de roulement. La première bague de palier (103) présente au moins un premier creux (105) dans lequel est disposé un dispositif de détection (110). Selon linvention, le dispositif de détection (110) est conçu pour détecter une grandeur détectée représentative des forces porteuses induites dans la première bague de palier (103).
