The invention discloses an energy-saving automobile driving device. The driving device comprises a driving shell, a traditional alloy hub, a magnetic pole engine and a vehicle suspension. A rear end cover is movably connected to the rear surface of the driving shell; the top of the driving shell is movably connected with a high-voltage wire interface; a stator iron core is movably connected into the driving shell; a permanent magnet magnetic pole is movably connected into the magnetic pole generator; a stator winding is movably connected into the magnetic pole engine; the top of the magnetic pole engine is movably connected with a small booster; the small booster changes the current resistance through the inductor, and the current is then transmitted to a semiconductor device and a crystalsensor for internal storage; finally, the boosted voltage is stabilized through a filter; the stator winding is wound in a wave-shaped winding mode, the stator iron core is arranged in the stator winding, the stator winding tightly surrounds the stator iron core, magnetic induction lines are cut on the stator winding through the magnetic poles of the permanent magnets to generate electric quantity, which is suitable for being used in an energy-saving automobile driving device and has wide development prospects in the future.
