摘要： A device for detecting speed in a braking system between two relatively rotatable elements, such as, the inner and outer rings of a roller bearing used to support a vehicle wheel. The device includes a first deflector mounted on one of the bearing rings having a magnetized ring member and a plurality of radially outwardly facing poles separated by non-magnetized spaces and a serrated annular member having a plurality of radially inwardly facing ribs. The device further includes a second deflector integral with a fixed ring of the bearing having at least one magnetic sensor engageable between the two bearing rings and spaced to intersect the magnetic fields to produced a plurality of signals per revolution. The signal produced by the sensor has a frequency proportional to the relative speed of the inner and outer bearing rings.

摘要： A sealing system for sealing the space between relatively rotatable members comprising a rigid support element and an annular elastomeric sealing element having an internal radial annular lip extending radially and axially from an annular root portion of the elastomeric element. The annular lip has a radial section of generally V-shaped cross section, having its vertex located obliquely with respect to the axis of the elastomeric element and comprising two portions of reduced cross section, one of the portions corresponding to the root portion and the other to the vertex of the V. Portions of reduced cross section divide the annular lip into first and second sections operable to engage with corresponding sealing surfaces on one of the members and having sufficient flexibility to hingedly connect the sections to one another and to the root portion.
