Problems solved by technology
[0005] Although it is possible to use such piston rods for pressure medium cylinders with pistons of different sizes that can be releasably coupled to the piston rod via screw connections, the production of such piston rods is still very expensive in terms of manufacturing technology, Because multiple cutting manufacturing steps are required

Embodiment Construction
[0021] according to figure 1 , the pressure medium cylinder basically comprises a cylinder housing 1 in which a piston 2 which can be acted upon by pressure medium on both sides is mounted axially displaceable. The piston rod 3 starts from the piston 2 and extends through the cylinder housing 1 toward the end face in order to conduct force outward. At the distal end of the piston rod 3 there is provided a connecting threaded element 4 for establishing a mechanical connection with a not further shown machine part to be driven. At the end opposite the connecting threaded element 4 , the piston rod 3 is fastened to the piston 2 by means of a releasable screwed connecting element 5 .
[0022] according to figure 2 , the piston rod 3 is of tubular design and formed from aluminum. The tubular piston rod 3 has a circular inner cross section 6 , in which a corresponding inner thread 7 a and 7 b is respectively provided towards both ends. The connecting thread element 4 can be con...

The invention refers to a pressure medium cylinder with a multipiece type piston rod, especially a pressure medium cylinder, comprising a piston (2) which is axially and movably installed in a cylinder shell(1) by pressure medium of at least one side; a piston rod (3) which is used for transmitting the force generated by the pressure loading piston (2) to the outside and is installed on the piston by a spiral connection component (5) which can be loosened, wherein the far side end of the piston rod (3) is provided with a connection screw element (4) in mechanical connection with machine components to be driven, wherein the piston rod (3) is designed to be a tubular shape and a tubular shaped circular inner cross section (6) is provided such that the connection screw element (4) can be screwed into the piston rod (3) from the far side end by an external thread (8); the spiral connection component (5) is designed according the design of a bolt and can be screwed into an opposite end of the tubular shaped piston rod (3).
Description
technical field [0001] The invention relates to a pressure medium cylinder with a piston mounted movably in a cylinder housing axially via pressure medium loading on at least one side, a piston rod for outwardly guiding the force generated by the pressure loading piston Mounting on the piston is via a releasable screw connection element, wherein a connection thread element is provided on the distal end of the piston rod for the mechanical connection to the machine part to be driven. [0002] The field of application of the invention extends to pressurized medium cylinders, which can be operated with compressed air or pressurized liquid and can be designed in this regard as pneumatic or hydraulic cylinders. The described solution can preferably be used for single or double-acting pneumatic cylinders, which preferably project on one side, but in special cases can also have a piston rod projecting on both sides. Background technique [0003] Such a pressure medium cylinder is ...
