The invention belongs to the technical field of friction power generation, and discloses an electromagnetic friction combined type suspension
energy recovery device which comprises a friction nanometer generator set and an
electromagnetic generator set, the friction nanometer generator set comprises a set shell, a sliding rack and a
patch electrode, the sliding rack is connected into the set shell in a sliding mode, and the
patch electrode is arranged in the set shell in an attached mode. Plastic sheets distributed at intervals are arranged on the side wall of the sliding rack, the
patch electrode comprises a conductive part and a
copper sheet, the
copper sheet is connected to the conductive part, and the plastic sheets and the
copper sheet perform friction power generation; a speed increasing
gear train is arranged in the unit shell, an
electromagnetic generator set is arranged on the outer wall of the unit shell, the speed increasing
gear train is connected to the rack in a meshed mode, and a gear shaft of a terminal gear of the speed increasing
gear train is connected with an input shaft of the
electromagnetic generator set. According to the electromagnetic friction combined type suspension
energy recovery device, energy of a suspension
system can be collected and stored, so that the energy can be used by other electrical parts of an automobile, and the energy utilization efficiency of the suspension
system is improved while
energy conservation and
environmental protection are achieved.
