Electric eddy-current speed reducer for vehicle

The utility model relates to an electric eddy current speed reducer for a vehicle. The utility model comprises a bracket 1, a stator framework, an excitation coil 3, an iron core 4, a magnetic yoke 5, a connecting ring 6, an impeller 7, and a rotor disk 8. The impeller 7 can be disassembled into a supporter 71, and an impeller part 72, and the casting technique can be simplified. When the shape of the vehicle is changed, the dimension of the outer circle of the connecting ring 6 needs to be changed, and the original impeller 7 can be used. Therefore, the expenses for making a mold newly can be saved, and the manufacturing cost is reduced. Besides, the utility model has the advantages of easy use, and high safety.
