A target magnet assembly configured to be secured to a rotating shaft of a steering gear assembly, the target magnet assembly comprising:
- an index hub with a mount, the mount comprising;
- a tab with a protrusion extending from the tab,
- a finger, and
- a stop;
- and
- a magnet secured by the mount, the magnet comprising an axial retention groove receiving the finger, a top surface abutting the stop, and a radial retention groove receiving the protrusion.
A stator assembly configured to be used as a component of a torque sensor for a steering gear assembly, the stator assembly comprising:
- a stator subassembly;
- and
- a target magnet assembly secured to the stator subassembly, the target magnet assembly comprising;
- an index hub with a mount, the mount comprising,
- a tab with a protrusion extending from the tab,
- a finger, and
- a stop, and
- a magnet secured by the mount, the magnet comprising an axial retention groove receiving the finger, a top surface abutting the stop, and a radial retention groove receiving the protrusion.
A method for securing a target magnet to a hub, the method comprising:
- providing a hub with a mount, the mount comprising;
- a tab with a protrusion extending from the tab,
- a finger, and
- a stop;
- providing a target magnet, the magnet comprising;
- an axial retention groove for receiving the finger, a top surface for abutting the stop, and a radial retention groove for receiving the protrusion;
- and
- inserting the target magnet into the mount, thereby causing the axial retention groove to receive the finger, the top surface to abut the stop, and the radial retention groove to receive the protrusion.
