ABSTRACT:
An eddy current type brake system connected to an output shaft of a transmission of a vehicle comprises a rotor connected to the transmission shaft, a stator movable relative to the rotor and a magnet mounted on the stator. The rotor has a ferromagnetic part and a non-magnetic or feeble-magnetic part. The magnet of the stator can move into the vicinity of the ferromagnetic part of the rotor to allow an eddy current to flow in the rotor. The magnet also can move into the vicinity of the non-magnetic or feeble-magnetic part of the rotor to prevent the eddy current from reaching the rotor. Therefore, when the magnet is moved into the vicinity of the ferromagnetic part, a brake force is applied to the rotor due to the eddy current whereas when the magnet is moved into the vicinity of the non-magnetic or feeble-magnetic part, the brake force is no longer applied to the rotor.
