DRAW COUPLER Russian patent published in 2018 - IPC B60D1/00 B62D53/00 B60D1/24 

FIELD: machine building.

SUBSTANCE: invention relates to the field of engineering and can be used in the creation of traction-coupling devices. Towing device comprises a magnetic grip mechanically coupled to this machine and adapted to interact with the surface of the trailing object and a controller coupled to the magnetic gripper. Magnetic gripper can be made on the basis of electro-permanent magnets and consist of components. Depending on the embodiments, the towing device may comprise protection and / or cleaning from contaminants, a vacuum pump coupled to the magnetic gripper, a winch for moving the magnetic gripper, for lifting the trailing object and for transferring some of its weight to the machine, a traction force sensor and / or an acceleration sensor, a sensor for approaching the magnetic gripper to the surface of the trailing object, elastic or damping device, which ensures smoothing of the force oscillations in the towing device.

EFFECT: improved reliability and traction are achieved with the trailer object.
