Title:
ELECTROMAGNETIC CLUTCH AND GEARBOX
Document Type and Number:
WIPO Patent Application WO/2019/061417
Kind Code:
A1
Abstract:
An electromagnetic clutch and a gearbox. The electromagnetic clutch comprises a main suction cup (2), a first suction cup (3), a second suction cup (4), an electromagnet assembly (300), a first locking assembly (7), and a second locking assembly (8). The main suction cup receives an external force by means of a connecting shaft and rotates. The first suction cup and the second suction cup are respectively located on two sides of the main suction cup, and are spaced apart from the main suction cup. The first suction cup and the second suction cup are capable of separately rotating relative to the main suction cup, and respectively exert force by the means of a first rotation shaft and a second rotation shaft. A magnetic field is generated when the electromagnet assembly is switched on. When a first magnetic field is generated, the first suction cup rotates with the main suction cup; when a second magnetic field is generated, the second suction cup rotates with the main suction cup. The first locking assembly follows the main suction cup and reciprocates between a first position and a second position, such that the first suction cup rotates or is fixed relative to the main suction cup. The second locking assembly follows the main suction cup and reciprocates between a third position and a fourth position, such that the second suction cup rotates or is fixed relative to the main suction cup.
