Title:
METHOD FOR PRODUCING A TUBULAR, ROTATIONALLY SYMMETRIC MOTOR VEHICLE CHASSIS COMPONENT SUCH AS A PISTON ROD, AND CONSTRUCTED PISTON ROD
Document Type and Number:
WIPO Patent Application WO/2011/098073
Kind Code:
A3
Abstract:
The invention relates to a method for producing a rotationally symmetric motor vehicle chassis component (1), wherein a tubular, rotationally symmetric part (2) and at least one rotationally symmetric projecting element (3) are jointed at ends facing each other axially. In order to achieve a high-strength joint without a welding process, the part (2) and the projecting element (3) are selected in combination according to the method having a radial play that is dimensioned such that, when an axially directed joining part (4) of the projecting element (3) is inserted into the end of the part (2), at least one adhesive bonding gap (11) extending axially between the inner and/or outer jacket (14 or 21) of the part (2) and at least one outside surface (12) of the joining part (4) are formed, whereupon the inner and/or outer jacket (14 or 21) of the part (2) and/or the at least one lateral face (12) of the projecting element (3) is provided with a layer of at least one cold-curing adhesive (13) over a section being equally long in the axial direction, the thickness of said layer corresponding to the radial dimension of the adhesive bonding gap (11) to be formed, and then the joining part (4) is inserted into the part (2) until a base part (5) of the projecting element (3) hits the end face (7) of the part (2), wherein the associated opening (8) of the part is closed by the base part (5), and the adhesive bonding gap (11) is filled with the adhesive (13), by means of which the adhesive bonding sections are adhesively bonded to form a high-strength joint that has a tensile shear strength withstanding a maximum pull-out force of 35 kN.
