Electromagnetic multistage adjustable variable inertance and variable damping device

An electromagnetic multistage adjustable variable inertance and variable damping device, comprising an outer sleeve, a first end cover, and a second end cover;

• the outer sleeve, the first end cover, and the second end cover forming a built-in cavity, wherein
• the built-in cavity comprises a driving shear plate, a first driven shear plate, a second driven shear plate, a transmission shaft, a thrust bearing, a first magnet yoke, and a second magnet yoke;
• the first magnet yoke is attached and fixed to the surface of one side, located in the built-in cavity, of the second end cover, and the second magnet yoke is attached and fixed to the surface of one side, located in the built-in cavity, of the first end cover;
• iron cores are arranged on the surface of one side, far away from the second end cover, of the first magnet yoke, the surfaces of the two sides of the driving shear plate, and the surface of one side, far away from the first end cover, of the second magnet yoke, and the iron cores are all fixedly connected to the surface of one side, far away from the second end cover, of the first magnet yoke, the surfaces of the two sides of the driving shear plate, and the surface of one side, far away from the first end cover, of the second magnet yoke;
• a first electromagnetic coil winding, a left second electromagnetic coil winding, a right second electromagnetic coil winding, and a third electromagnetic coil winding are arranged outside the iron cores in the surface of one side, far away from the second end cover, of the first magnet yoke, in the driving shear plate, and in the surface of one side, far away from the first end cover, of the second magnet yoke in sequence in a surrounding manner;
• permanent magnets are arranged on the surfaces of both sides of the first driven shear plate and the second driven shear plate;
• the permanent magnets are annularly arranged around the transmission shaft;
• the permanent magnets are all fixedly connected to the surfaces of both sides of the first driven shear plate and the second driven shear plate;
• air gaps are formed between the iron cores and the permanent magnets;
• the driving shear plate and the transmission shaft are fixed integrally;
• the first driven shear plate is connected to the second driven shear plate through the thrust bearing and the transmission shaft;
• the first driven shear plate and the second driven shear plate may rotate relative to the transmission shaft.
