Patent number: 10279820Abstract: A spring lock for a secondary spring that is arranged between the car body and the under frame of a rail vehicle. A spring locking element is provided which in the mounted state is supported on the car body and projects through a cutout and is connected to the secondary spring in such a way that it is prevented from extending. This facilitates the mounting of anti-wear washers under the secondary spring to a considerable degree.Type: GrantFiled: August 6, 2012Date of Patent: May 7, 2019Assignee: Siemens AG OesterreichInventor: David Kreuzweger

Patent number: 9694831Abstract: A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.Type: GrantFiled: April 4, 2013Date of Patent: July 4, 2017Assignee: SIEMENS AG OESTERREICHInventors: David Kreuzweger, Christian Plankensteiner, Michael Sumnitsch
