Patent number: 5287738Abstract: A target carrier is clamped between a constant velocity joint and a spindle bearing inner race such that an encoded target mounted on the target carrier rotates with a wheel spindle over which the spindle bearing inner race is mounted. A sensor probe is mounted on a steering knuckle within which the constant velocity joint is mounted for the encoded target and for generating a signal indicative of rotation of the wheel spindle. The target carrier may be held by a capturing cup before installation of the constant velocity joint and may serve as a pilot during installation of the constant velocity joint.Type: GrantFiled: October 30, 1992Date of Patent: February 22, 1994Assignee: The Torrington CompanyInventors: Mark A.

Patent number: 5067350Abstract: A device to determine rotational parameters of a rotatable shaft mounted within a stationary tube comprising a substantially annular shaped target. The target is attached to a rotatable shaft. A target retainer has a bore for receiving the rotatable shaft, and is dimensioned to be securely attached to an interior surface of the tube. The target retainer has a radially extending surface adjacent each axial end of the target to restrain axial movement of the target, and also has an aperture adjacent the outer periphery of the target. A sensor extends into the aperture when the sensor is mounted on the stationary tube. Fasteners connect the sensor to the stationary tube.Type: GrantFiled: December 14, 1990Date of Patent: November 26, 1991Assignee: The Torrington CompanyInventors: John M. Grillo, James A.

Patent number: 5017866Abstract: A magnetic field source is mounted on one race of a two-race radial or thrust bearing. The race with the magnetic field source rotates. The other race does not rotate. A magnetic field sensor is mounted on a flexible arm of a rigid arm support. The arm support with its flexible arm does not rotate but the flexible arm may flex in response to movement of either of the races or the flexible arm support member so that the magnetic field sensor is always kept a constant predetermined distance from the magnetic field source. The number of times alternate magnetic poles on the rotating race is sensed by the sensor per unit of time indicates the speed of the rotating race.Type: GrantFiled: February 8, 1990Date of Patent: May 21, 1991Assignee: The Torrington CompanyInventors: Alfred J. Santos, James A. Hilby, Scott M. Duncan

Patent number: 4915512Abstract: One thrust race of a two-race thrust bearing has a magnetic field sensor mounted on a lip extending axially from the outside diameter of the thrust race. The other thrust race has a magnetic field source. The race with the magnetic field source rotates; the race with the sensor is fixed. The number of times alternate magnetic poles on the rotating thrust race is sensed by the sensor per unit of time indicates the speed of the rotating thrust race.Type: GrantFiled: March 24, 1989Date of Patent: April 10, 1990Assignee: The Torrington CompanyInventors: James A.
