A wheel assembly essentially characterized by comprising a cylinder having a piston rod projecting slidably therein from the end; connection elements on the free ends of the cylinder and piston rod; a piston on the rod inside the cylinder; an annular valve body in the cylinder in spaced relationship with the piston in the direction of its displacement in the extension of the connecting rod by sliding the piston rod through said body; a check valve associated with the body that opens away from the piston; another check valve related to the body that opens towards the piston and the body and spring means that normally oppose resistance to the opening of said retention valves but that allow their opening under certain excess pressure inside the chamber including said means a helical compression spring that surrounds the piston rod beyond the end of the valve body in front of the piston, said valve comprising a control element exposed and connected to the spring.
