  • Patent number: 7832287
    Abstract: An assembly for positioning a torque sensor having a receiver and a transmitter is provided. The assembly includes a first annular member, wherein the receiver is coupled to the first annular member. A second annular member is disposed proximate the first annular member. A bearing assembly is disposed between the first annular member and the second annular member. The bearing assembly includes a first race formed to the first annular member, a second race formed to the second annular member, and a bearing disposed between the first race and the second race for allowing the first race and the second race to rotate relative to one another. A radially extending member is coupled to the second race. The receiver is radially displaced from the bearing assembly and the transmitter is mounted to a mounting surface of the radially extending member opposite the receiver at a predefined axial distance.

  • Patent number: 7757570
    Abstract: A torque sensor for sensing torque in a rotatable shaft. The rotatable shaft is configured to rotate within a shaft housing. The sensor housing has a first end, a second end, and at least one sensing zone. At least one target zone is disposed on the rotatable shaft and substantially opposes the at least one sensing zone. At least one bearing member is disposed between the sensor housing and the rotatable shaft for limiting relative axial movement and allowing relative rotation between the sensor housing and the rotatable shaft. A first resilient member has a first end in contact with the first end of the sensor housing and a second end in contact with an interior wall of the shaft housing. A second resilient member has a first end in contact with a retaining member and a second end in contact with the second end of the sensor housing.
