Anterior damping device of electric motor car

The application discloses an anterior damping device of electric motor car, including backup pad, sheath and shielded box, backup pad both sides tip is provided with the sheath, the sheath bottom surface is provided with the oil filler point, the inside side of sheath is provided with the oil groove, the oil groove inboard is provided with the pillar, pillar top surface tip is provided with the stopper, the stopper top surface is provided with the mount pad, pillar bottom surface tip is provided with the sliding sleeve, the sliding sleeve with be provided with buffer spring between the stopper. Beneficial effect lies in: this device drives the sliding sleeve through the kicking block and slides on the pillar to converting vibrations into elastic potential energy through stretching out anddrawing back of buffer spring and carrying out the shock attenuation, promoted the shock attenuation effect, prolonged the stability in use of electric motor car, the while can be acquireed the amplitude of vibration informat
