The invention relates to a cylinder housing (2) of lightweight construction hybrid construction for a pressure cylinder (1), said cylinder housing having a load-bearing structure (4) comprising An inner tube (6) with open ends (7, 8) and first and second end pieces (10, 11) in the region of the ends (7, 8) of the inner tube (6). A composite structure (12) consisting of thread-reinforced plastic is arranged on the outer surface (13) of the inner tube (6). On the outer surfaces (16) of the first and second end pieces (10, 11), a plurality of rod-shaped shafts protruding from the outer surface (16) are arranged in a distributed manner on the periphery of the first and second end pieces, respectively. Winding auxiliary element (17). The winding aid element (17) has such a strength that when applying the threads of the composite structure (12), a winding process can be carried out, in which the individual threads of the composite structure (12) are each directed away from each other in the axial direction Distributed around at least one winding aid (17) in the deflection region (18) on the side of the winding. After forming the composite structure (12), the winding aid element (17) is deformed and embedded at least partially in the composite structure (12). The invention also relates to a pressure cylinder (1) with such a cylinder housing (2) and a method for its production.
Description
technical field [0001] The invention relates to a lightweight hybrid cylinder housing for a pressure cylinder, a pressure cylinder with such a cylinder housing, and a lightweight hybrid cylinder housing for a pressure cylinder Cylinder housing method. Background technique [0002] A lightweight hybrid cylinder housing for a pressure cylinder designed in this manner is known from EP 0 464 202 A1. The cylinder housing has a load-bearing structure comprising an inner tube with ends spaced apart from one another in the axial direction, wherein the longitudinal axis extends between the ends. A first and a second end piece are respectively arranged in the end region of the inner tube. A composite structure consisting of wire-reinforced plastic is provided on the outer surface of the inner tube. The composite structure extends axially continuously between the first and second end pieces. Distributed on the outer surface of the first and second end piece over their circumference...
