PISTON HOUSING FOR AIR SPRING

The present invention relates to an air spring (1), providing the suspension between the cab and the frame in the vehicles, comprising at least one body (2); at least one cover (4); at least one bellow (3) that extends between the body (2) and the cover (4) in an airtight manner; at least one piston (6) that moves according to the distance between the cab and the frame; at least one control valve (5) that adjusts the air pressure inside the bellow (3) according to the movement of the piston (6); at least one housing (9) that enables the piston (6) to be mounted to the body (2) so as to axially move according to the change in the distance; at least one flange (7) that surrounds the end of the piston (6) facing the cover, that limits the movement of the piston (6) in the direction of the body (2) and that is integrated with the piston (6); at least one stopper (10) that is disposed at the other end of the piston (6) and that extends from the piston (6) to the housing (9) as a protrusion; at least one channel (8) that is arranged inside the housing (9), and at least one step (11) that is arranged on the at least one channel (8) wherein the stopper (10) moves and that limits the axial movement of the piston (6).
