Abstract
This support member (60) holds at least two sensors (80) with respect to a rotating encoder washer (20) of a rolling bearing assembly (2). It includes an annular ring (62) centered on a central axis (X60) and provided with an inner radial surface (64) which forms an abutment and centering means for each sensor (80) with respect to the central axis (X60). The support member also includes foot parts (70) extending perpendicularly with respect to the inner radial surface (64) and provided with holes (72, 74, 76) adapted for the passage of connection pins (82, 84, 86) of the sensors (80), in order to connect these sensors (80) to a printed circuit board (50).
Claims15
A support member for holding at least two sensors with respect to a rotating encoder washer, wherein said support member has:
- an annular ring centered on a central axis and provided with an inner radial surface which forms an abutment and centering means for each sensor with respect to the central axis, and
- foot parts extending perpendicularly with respect to the inner radial surface and provided with holes adapted for a passage of connection pins of said sensors.
A rotation detection device comprising:
- an encoder washer,
- several sensors mounted around said encoder washer, and
- a printed circuit board supporting electronic components adapted to process output signals of said sensors, wherein
- said sensors are mounted on a support member, with their connection pins going through the respective holes of said foot parts, so that each sensor is connected to said printed circuit board, and wherein
- each sensor is in abutment against said inner radial surface of said annular ring of said support member, and wherein the support member comprises:
- an annular ring centered on a central axis and provided with an inner radial surface which forms an abutment and centering means for each sensor with respect to the central axis, and
- foot parts extending perpendicularly with respect to the inner radial surface and provided with holes adapted for a passage of connection pins of said sensors.
A rolling bearing assembly comprising a fixed outer ring, a rotating inner ring and a rotation detection device, the encoder washer of said rotation detection device being fast in rotation with said inner ring, and the rotation detection device comprises:
- an encoder washer,
- several sensors mounted around said encoder washer, and
- a printed circuit board supporting electronic components adapted to process output signals of said sensors, wherein
- said sensors are mounted on a support member, with their connection pins going through the respective holes of said foot parts, so that each sensor is connected to said printed circuit board, and wherein
- each sensor is in abutment against said inner radial surface of said annular ring of said support member, and wherein the support member comprises:
- an annular ring centered on a central axis and provided with an inner radial surface which forms an abutment and centering means for each sensor with respect to the central axis, and
- foot parts extending perpendicularly with respect to the inner radial surface and provided with holes adapted for a passage of connection pins of said sensors.
