VIBROPROPULSIVE DEVICE FOR MOVEMENT ALONG FERROMAGNETIC SURFACE Russian patent published in 2001 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to devices using vibrator as propulsive unit. Proposed vibropropulsive device has hollow housing in form of nonmagnetic disk installed for rolling on ferromagnetic surface, electric pulse source and mechanical vibration generator hinge-suspended from horizontal axle of housing for swinging in perpendicular plane. Generator is made in form of two ring coaxial coils with windings placed in cylindrical nonmagnetic housing, ferromagnetic cylindrical core installed concentrically in axial holes of coils and flexible secured between two cylindrical springs. Electric pulse source is connected with coil windings through remote contact device for separate connection of coils. Housing of vibropropulsive device is partially filled with magnetic liquid so that liquid surface contacts with casing of mechanical vibration generator. EFFECT: reduced power consumption at motion, simplified design. 2 dwg
