Abstract
A magnet assembly retained on the rotor of a rotary position sensor such as, for example, the drum of a vehicle pedal. The drum of the vehicle pedal includes a retention pocket for the magnet assembly. In one embodiment, the magnet assembly includes a magnet with a pair of spaced apart legs and a pair of pole pieces abutted against the exterior of the legs. Each of the pole pieces includes a plurality of pointed barbs that are pressed into the material of the retention pocket on the drum of the vehicle pedal to retain the magnet assembly on the vehicle pedal.
Claims13
A magnet assembly adapted for retention on the rotor of a rotary position sensor assembly, the magnet assembly comprising:
- a magnet;
- and
- a pair of metal pole pieces attached to the magnet and each defining at least a first barb adapted to be pressed into the material of the rotor to retain the magnet assembly on the rotor of the rotary position sensor assembly.
A vehicle pedal assembly comprising:
- a pedal including a distal drum defining a pocket;
- and
- a magnet assembly retained on the drum of the pedal, the magnet assembly including a pair of spaced apart legs and a pair of metal pole pieces abutted against the exterior surface of the pair of legs of the magnet respectively, each of the pair of pole pieces including a pair of spaced apart and angled side edges defining first and second pairs of barbs that are pressed into the material of the pocket in the drum for retaining the pole pieces and the magnet assembly on the drum of the pedal.
An assembly for retention of a magnet on a rotor of a non-contacting sensor assembly that is made of a plastic materiel and comprising at least a first barb on the magnet that is pressed into the plastic material of the rotor for retention of the magnet on the rotor.
