Abstract
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.
Claims24
A sensor system for use with an antilock brake, constant velocity joint, spindle bearing inner race and steering knuckle, the sensor system comprising:
- an encoded target;
- target mounting means, adapted to be clamped between said constant velocity joint and said spindle bearing inner race, for mounting the encoded target for rotation with said wheel spindle over which the spindle bearing inner race is mounted;
- and
- probe means, adapted to be mounted on said steering knuckle within which the constant velocity joint is mounted, for sensing the encoded target and for generating a signal indicative of rotation of the wheel spindle.
A method of mounting a sensor system for use with an antilock brake, constant velocity joint, spindle bearing inner race and steering knuckle, the method comprising:
- providing a capturing cup and a subassembly, the subassembly including an encoded target and a target carrier;
- mounting the capturing cup on said steering knuckle, before said constant velocity joint is installed in the steering knuckle, such that the subassembly is captured by the capturing cup;
- installing the constant velocity joint in the steering knuckle such that the target carrier pilots the subassembly and such that a portion of the subassembly is clamped between the constant velocity joint and said spindle bearing inner race;
- and
- mounting a sensor probe on the steering knuckle such that the sensor probe senses the encoded target and generates a signal indicative of rotation of a spindle over which the spindle bearing is mounted.
A method of mounting a sensor system for use with an antilock brake, constant velocity joint, wheel spindle, spindle bearing and steering knuckle, the method comprising:
- providing a subassembly including an encoded target and a target carrier;
- mounting the subassembly on an outer surface of said constant velocity joint before the constant velocity joint is installed in said steering knuckle;
- installing the constant velocity joint in the steering knuckle;
- and
- mounting a sensor probe on the steering knuckle such that the sensor probe senses the encoded target and generates a signal indicative of rotation of said wheel spindle over which said spindle bearing is mounted.
A sensor system for use with an antilock brake, constant velocity joint, wheel spindle, and steering knuckle, the sensor system comprising:
- an encoded target;
- target mounting means, adapted to be mounted on an outer surface of said constant velocity joint for mounting the encoded target for rotation with said wheel spindle fixed to the constant velocity joint;
- and
- probe means, adapted to be mounted on said steering knuckle and in proximity to the encoded target, for sensing the encoded target and for producing a signal indicative of rotation of the wheel spindle.
