The bearing has a path forming an air passage between exterior of a fixed unit (2) and a front side of a rotating unit. The path includes an outer channel (25) and an inner channel (26) to traverse through each unit. The path includes a groove formed by su...

The assembly has a bearing (2) rotating a journal (3) with respect to a frame. The bearing has inner rings fixed on journal`s outer wall and is axially immobilized on the wall by a spacer (19). The spacer is integrated with a fretting corrosion reduction u...

The system has a synchronization unit (7) coupled to a sensor (6) and a detection device (4), and including a determination device to determine an activation position of the device (4) when a transponder (3) is in transmission/reception cone of communicati...

The system has a sensor (6) and a detection device (4) coupled to a frame. A speed measuring unit measures rotation speed of a rotating unit. An activation device (7) is connected to the sensor and the detection device, and activates the detection device a...

The system has an activation device (7) connected to a sensor (6) and detection device (4) of parameter issued from transponder (3) mounted on a valve of a tire. The activation device activates the detection device, according to an absolute position of cod...

The vehicle suspension stop has an upper fixed ring (1) and lower moving ring (3) which contain ball bearings (5). The vehicle wheel suspension spring (4) bears on to the lower ring through a dish (7) such that when it turns under vertical pressure the amo...

The suspension stop includes a deformation sensor (12) which measures the deformations of a top race (1) and a top cup (6). A calculating unit computes the forces applied to the top race and the top cup, based on the measured deformations.
