Abstract
An eddy current braking apparatus is disclosed. The apparatus includes a stator, a coil of wire, and a drum. The stator has a plurality of poles and is mountable to a frame of a vehicle. The coil of wire is wound about each of the plurality of poles and wherein adjacent coils are electrically connected to form an electromagnet. The drum is adapted to receive a wheel and tire assembly and wherein the drum is rotatably mounted to a vehicle axle, and wherein an eddy current is developed between the drum and the stator, from the relative motion of the drum with respect to the stator, thereby retarding rotation of the drum and wheel and tire assembly.
Claims17
An eddy current braking apparatus, comprising:
- a stator having a plurality of poles, wherein the stator is mountable to a frame of a vehicle;
- a coil of wire wound about each of the plurality of poles, wherein adjacent coils are electrically connected to form an electromagnet;
- and
- a drum receiving a wheel and tire assembly wherein the drum is rotatably mounted to a vehicle axle, a frictional brake fixed to the vehicle frame and adapted for frictional contact with the drum, thereby preventing rotation of the drum;
- and
- wherein an eddy current is developed between the drum and the stator, from the relative motion of the drum with respect to the stator, thereby retarding rotation of the drum and wheel and tire assembly.
