Abstract

A vehicular wheel bearing assembly with relatively rotatable bearing rings (11, 10) and rolling elements (12) therebetween incorporates a sensing arrangement for sensing speed or position.. The sensing arrangement is composed of pre-formed annular encoders (21, 23) with alternate magnetic north and south poles which are offset both radially and axially relative to the rotational axis defined by the bearing rings (10, 11). The encoders (21, 23) are mounted on different components of the assembly, for example on a cage (19) and one of the bearing rings (10) which is intended to rotate. Sensors (28, 29) in a housing (25) fitted to the outer bearing ring (11) intended to remain stationary detect the movement of the poles of the respective encoders (21, 23) to generate electrical signals which can be combined or processed separately. In an alternative embodiment, only on encoder mounted on the cage is used, with a sensor on another part of the assembly.

Claims (13)

  1. 9. A wheel bearing assembly composed of inner and outer bearing rings, one of which is intended to rotate and the other of which is intended to remain stationary, two sets of rolling elements between the rings and in angular contact with tracks defined by the rings, each set of rolling elements being spaced in the direction of the axis of rotation with each set of rolling elements retained by one of two cages and a sensing arrangement composed of at least two annular encoders with alternate north and south magnetic poles and at least two sensors operably associated with the encoders and each serving to provide electrical signals generated by the passage of the poles of the associated encoder;
    wherein one of the encoders is mounted on the rotatable one of the bearing rings and, the other of the encoders is mounted an one of the cages and each of said sensors and encoders is disposed axially, between the sets of rolling elements.
  2. 2. An assembly according to claim 1, wherein the magnetic poles of the encoders are orientated parallel to the rotational axis.
  3. 3. An assembly according to claim 1, wherein the magnetic poles of the encoder are orientated radially relative to the rotational axis.
  4. 4. An assembly according to claim 1, wherein the magnetic poles of at least one of the encoders are orientated radially relative to the rotational axis and the magnetic poles of at least one other of the encoders are orientated parallel to the rotational axis.
  5. 5. An assembly according to claim 1, wherein the encoders are spaced in a radial and an axial sense.
  6. 6. An assembly according to claim 1, wherein the encoders are spaced axially but aligned radially in relation to the rotational axis.
  7. 7. An assembly according to claim 1, wherein the encoder mounted on said rotatable race is mounted on a component mounted onto said race.
  8. 8. An assembly according to claim 1, wherein the sensors are mounted in a housing fitted into a bore in the other stationary bearing ring so the housing locates the sensor in sensing vicinity to the associated encoders.

  10. 10. An assembly according to claim 1 wherein a third encoder is mounted for rotation on the other of the cages.
  11. 11. A wheel bearing assembly composed of inner and outer bearing rings, one of which is intended to rotate and the other of which is intended to remain stationary, sets of rolling elements between the rings and in angular contact with tracks defined by the rings, the sets of rolling elements being spaced in the direction of the axis of rotation with each set of rolling elements retained by a cage and a sensing arrangement composed of at least two annular encoders with alternate north and south magnetic poles and at least two sensors operably associated with the encoders and each serving to provide electrical signals generated by the passage of the poles of the associated encoder;
    wherein one of the encoders is mounted on the rotatable one of the bearing rings and, the other of the encoders is mounted on one of the cages and wherein the inner bearing ring is secured onto a wheel hub, a cover is located on the other bearing ring to enclose the sensors and is carried by an axial portion of the cover.
  12. 12. An assembly according to claim 11, wherein, the sensors are mounted on an elongate carrier adjustably supported in a mounting fitted to the other bearing ring wherein the encoder is mounted on the cage of one of the sets of rolling elements and the sensor is mounted on the stationary bearing ring.
