US Patent 9981553 Wheel powered alternator charging system

A wheel powered alternator charging system captures rotational energy of a vehicle wheel, transferring the rotational energy to an alternator to generate electricity. An alternator, a mounting bracket, and a transfer shaft are mounted to a support frame. An input wheel is connected to an existing wheel on the vehicle. The input wheel is connected to the transfer shaft by a first pulley assembly. A second pulley assembly is connected between the transfer shaft and an alternator wheel. As the vehicle wheel rotates, mechanical energy is transferred through the first pulley assembly, the transfer shaft, and the second pulley assembly to the alternator. The mounting bracket is affixed to the vehicle frame.
