Embodiment Construction

[0036] First of all, it should be determined that in differently described implementation forms, the same components have the same reference signs or the same component names, and the disclosure contained in the entire specification can be reasonably transferred to have the same reference signs or the same component names. The same part of the component name. The position descriptions selected in the description, such as upper, lower, side, etc., also refer to the current description and the illustrated drawings, and can be reasonably transferred to a new position when the position is changed.

[0037] in figure 1 A working cylinder in the form of a pressure cylinder 1 is shown in simplified form. The pressure cylinder includes a cylinder housing 2 in the form of a hybrid light-weight structure and a piston not shown in detail here and a piston rod 3 connected thereto. The pressure cylinder may be, for example, a hydraulic cylinder, a pneumatic cylinder or a hydropneumatic cylind...

Abstract

The invention relates to a cylinder housing (2) for a pressure cylinder (1) of lightweight / hybrid construction, having a support structure (4) comprising an inner tube (6) with ends (7, 8) that are spaced apart in the axial direction, and a first and a second end piece (10, 11) in the region of one of the ends (7, 8) of the inner tube (6). A composite structure (12) made of a fibre-reinforced plastics material is arranged on an outer surface (13) of the inner tube (6). Arranged on an outer surface (16) of the first and the second end piece (10, 11) in each case in a manner distributed over the circumference thereof are a plurality of rod-like winding aids (17) that protrude from the outer surface (16). The winding aids (17) have sufficient strength to allow a winding operation during the application of the threads of the composite structure (12), individual threads of the composite structure (12) being guided during said winding operation around at least one of the winding aids (17) in a deflection region (18) on sides that face away from one another in each case in the axial direction. Following the formation of the composite structure (12), the winding aids (17) are reshaped and at least regionally embedded in the composite structure (12). The invention also relates to a pressure cylinder (1) having such a cylinder housing (2) and to a method for the production thereof.

Description

Technical field [0001] The present invention, as described in claims 1, 13 and 14, relates to a light-weight structure mixed structure type cylinder housing for a pressure cylinder, a pressure cylinder with such a cylinder housing, and a type for manufacturing A method of mixing the structure of the cylinder shell with the lightweight structure of the pressure cylinder. Background technique [0002] A light-weight structure hybrid structure cylinder housing for pressure cylinders constructed as described above is known from EP0464202A1. The cylinder housing has a bearing structure that includes an inner tube having ends spaced apart from each other in the axial direction, wherein a longitudinal axis extends between the ends. The first and second end pieces are respectively arranged in the end regions of the inner tube. A composite structure composed of thread-reinforced plastic is arranged on the outer surface of the inner tube. The composite structure extends continuously bet...
