Abstract
An assisted thrust system for a carriage provided with wheels that includes a base to which a first directional wheel and a second directional wheel are fixed that are connected to the base so as to be able to rotate around a respective axis perpendicular to the base; to the base a first drive wheel and a second drive wheel are further fixed that are rotated by at least one gearmotor unit, which drives the first drive wheel by a first magnetic coupling device and the second drive wheel by a second magnetic coupling device.
Claims16
An assisted thrust system for a carriage provided with wheels, wherein the carriage comprises a base to which a first directional wheel and a second directional wheel are fixed that are connected to the base by respective support elements that can rotate in relation to the base around a respective axis that is perpendicular to the base, wherein a first drive wheel and a second drive wheel are further fixed to the base and rotated by at least one gearmotor unit, wherein said at least one gearmotor unit drives said first drive wheel by a first magnetic coupling device and said second drive wheel by a second magnetic coupling device, wherein said at least one gearmotor unit comprises a first gearmotor unit that drives said first drive wheel and a second gearmotor unit that drives said second drive wheel, wherein said first magnetic coupling device includes a first disc made of electrically conductive material and a second disc made of electrically conductive material that are fitted on an a first outlet shaft of the first gearmotor unit, a first group of permanent magnets and a second group of permanent magnets inserted into respective first seats with which the first drive wheel is provided, wherein said first drive wheel is arranged between said first disc and said second disc on said first outlet shaft free to rotate in relation thereto, wherein said first disc is inserted with clearance into a first seat obtained in said first drive wheel and faces said first group of permanent magnets, wherein said second disc is inserted with clearance into a second seat obtained in said first drive wheel in a position opposite said first seat and faces said second group of permanent magnets, and wherein said second magnetic coupling device includes a third disc made of electrically conductive material and a fourth disc made of electrically conductive material that are fitted on second outlet shaft of the second gearmotor unit, a third group of permanent magnets and a fourth group of permanent magnets inserted into respective second seats with which the second drive wheel is provided, wherein said second drive wheel is arranged between said third disc and said fourth disc on said second outlet shaft and is free to rotate in relation thereto, in which said third disc is inserted with clearance into a third seat obtained in said second drive wheel and faces said third group of permanent magnets, wherein said fourth disc is inserted with clearance into a fourth seat obtained in said second drive wheel in a position opposite said third seat and faces said fourth group of permanent magnets.
An assisted thrust system for a carriage provided with wheels, wherein the carriage comprises a base to which a first directional wheel and a second directional wheel are fixed that are connected to the base by respective support elements that can rotate in relation to the base around a respective axis that is perpendicular to the base, wherein a first drive wheel and a second drive wheel are fixed to the base and rotated by at least one gearmotor unit, wherein said at least one gearmotor unit drives said first drive wheel by a first magnetic coupling device and said second drive wheel by a second magnetic coupling device, wherein said at least one gearmotor unit comprises a single gearmotor unit that drives both said first drive wheel and said second drive wheel, wherein said first drive wheel and said second drive wheel are arranged at opposite ends of an axle free to rotate in relation thereto, said axle being rotated by said single gearmotor unit, wherein said first magnetic coupling device includes a first disc made of electrically conductive material and a second disc made of electrically conductive material that are fitted on said axle, a first group of permanent magnets and a second group of permanent magnets inserted into respective seats provided in the first drive wheel, wherein said first drive wheel is arranged between said first disc and said second disc on said axle and is free to rotate in relation thereto, in which said first disc is inserted with clearance into a first seat obtained in said first drive wheel and faces said first group of permanent magnets, in which said second disc is inserted with clearance into a second seat obtained in said first drive wheel in a position opposite said first seat and faces said second group of permanent magnets, wherein said second magnetic coupling device includes a first disc made of electrically conductive material and a second disc made of electrically conductive material that are fitted on said axle, a first group of permanent magnets and a second group of permanent magnets inserted into respective seats provided in the second drive wheel, wherein said second drive wheel is arranged between said first disc and said second disc on said axle and is free to rotate in relation thereto, in which said first disc is inserted with clearance into a first seat obtained in said second drive wheel and faces said first group of permanent magnets, wherein said second disc is inserted with clearance into a second seat obtained in said second drive wheel in a position opposite said first seat and faces said second group of permanent magnets.
