Abstract
A sensor for sensing the rotation of an output shaft of a motor used for driving a vehicle includes a disc on the output shaft that carries magnets facing toward a motor carrier and the motor. The motor carrier has an annular recess open on a side facing away from the motor, and a Hall effect sensor is placed in this recess and held with a T-shaped bracket having a tang that supports the Hall effect sensor partially in this annular recess for protecting it and positioning it adjacent the magnets on the disc.
Claims9
A sensor for sensing rotation of an output shaft motor having a motor carrier, the motor carrier having a recess on a side thereof, facing the output shaft, a disc on the output shaft of the motor having identifiable indicia carried at a known radial positions and arranged annularly around the disc, the disc having a plane oriented substantially perpendicular to the output shaft and a sensor supported in the recess of the motor carrier for sensing the indicia, a bracket for supporting the sensor comprising a T-shaped support having a depending tang extending into the recess and supporting an end of the sensor adjacent the disc carrying the indicia.
In a skid steer loader having a frame, a hydraulic drive motor for driving wheels on the skid steer loader, a motor carrier for the hydraulic motor, the motor having an output shaft, and the motor carrier being mounted onto the frame, the improvement comprising a sensor for sensing the rotation of the output shaft of the motor including a disc carrying a plurality of annularly spaced magnets thereon, the disc having a plane and the plane substantially perpendicular to the output shaft, and a Hall effect sensor supported on the motor carrier and having an end facing the magnets to sense passage of the magnets pass the sensor.
