Protection device for a speed sensor, the sensor being provided with a reading surface which is arranged at a first determined distance from an encoder of a contact rolling bearing, and the protection device being coupled to the contact rolling bearing, and presenting a housing for the sensor, and at least one scraping element which is arranged in such a way as to face the encoder itself in order to remove any eventual impurities from the encoder.

Protection device for a speed sensor

Sealing device () for a wheel hub group () which is connected to a differential device, and which is provided with a rolling contact bearing (), the sealing device being provided with a first shield () which is shrink-fit onto an inner race () of the rolling contact bearing (), and an encoder () which is integral with the first shield () in order to generate a signal for reading the functioning kinematic parameters of the wheel hub group (), and is also provided with a second shield () which is shrink-fit onto an outer race () of the rolling contact bearing () in a position which is opposite to and which is also external to the inner shield; a static sealing element () is integral with the second shield (), and is also arranged in contact with a containing box of the differential in order to define a watertight chamber () in order to provide a reading surface of a reading sensor () which can read the signal which is generated by the encoder itself.

Sealing device for a wheel hub unit

Protection device () for an encoder () in a rolling bearing () presenting an outer race () which is arranged in contact against a fixed support (), the device being interposed between the encoder () itself and a reading sensor () which is supported by the support () itself, and being provided with: a fixing race () which is shrink fit onto the outer race () of the bearing () and frontally to a shoulder () of the support (); a protection shield () which extends from the fixing race () towards an inner race () of the bearing () in a position which is frontal to both the encoder () and the sensor (); and a sealing element (), which is integral to the fixing race () and the shoulder () for the static waterproofing of the support ().
