Abstract
In a method of connecting chassis parts to produce a chassis assembly, at least one end of a first chassis part is connected with a second chassis part in an overlap zone by a form fit and an interference fit through an internal high pressure joining process. The second chassis part serves hereby a seal of the one end of the first chassis element.
Claims4
A method of connecting chassis parts, comprising the step steps of:
- placing one end of a first chassis part in an end of a second chassis part to define an overlap zone;
- introducing a fluid into the first chassis part at an internal high pressure to press a wall part of the first chassis part in the overlap zone outwards into a through opening in a wall of the second chassis part against a counter member configured as a plunger received in the through opening;
- and
- pushing the plunger into the through opening against a confronting surface of the wall part of the first chassis part to produce an undercut between the wall part of the first chassis part and the wall of the second chassis part and thereby force a portion of the wall part into a recess of a step surface of the first chassis part.
