Load distribution apparatus of magnetic wheel

A load distribution apparatus of a plurality of magnetic wheels, comprising:

• a plurality of cylinder parts each including one side respectively connected to one of the plurality of magnetic wheels and an upper space portion and a lower space portion whose interiors do not communicate to each other;
• and
• a passage part which serves as a moving path of fluid and interconnects the plurality of cylinder parts,
• wherein the passage part is configured to evenly distribute a load applied to the magnetic wheels by moving fluids in the upper space portion and the lower space portion of the respective cylinder part in such a manner that the fluids are not mixed,
• wherein the plurality of cylinder parts each further includes:
• a cylinder body partitioned into the upper space portion and the lower space portion by a piston elevatably provided in the cylinder body;
• and
• a piston rod including one side connected to the piston and the other side connected to the respective magnetic wheel, and
• wherein a stopper to limit a descent height of the cylinder body and to balance the apparatus is provided on the piston rod associated with a foremost magnetic wheel located along a frame of the apparatus, and a stopper to limit the descent height of the cylinder body and to balance the apparatus is provided on the piston rod associated with a rearmost magnetic wheel located along the frame of the apparatus.
