Patent number: 10322731Abstract: A secondary spring for a rail vehicle springs a wagon body of the rail vehicle on the chassis of the rail vehicle. The secondary spring is divided along a predefined axis into a first and at least one further, second section. The first section is configured to be axially stiff and springy orthogonally to the predefined axis, and the second section is configured to be stiff orthogonally to the predefined axis and axially springy. The secondary spring contains at least one horizontal stop, which is arranged on the secondary spring such that a force which acts on the horizontal stop orthogonally to the predefined axis is introduced into the secondary spring between the first and the second section.Type: GrantFiled: November 13, 2014Date of Patent: June 18, 2019Assignee: Siemens Mobility GmbHInventors: Helmut Distler, Michael Sumnitsch

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

Patent number: 9637145Abstract: A rail vehicle includes at least one running gear and at least one anti-roll stabilizer which is connected to two different vehicle parts of the rail vehicle. The anti-roll stabilizer includes a torsion shaft disposed on a vehicle part transversally to the longitudinal direction of the vehicle, levers anti-rotationally disposed on the torsion shaft at both sides of the longitudinal axis of the vehicle and a respective draw/push rod for each lever. Each lever is articulatingly connected to one end of the draw/push rod and the draw/push rod is articulatingly connected at its other end to the other vehicle part. In order to reduce the dynamic forces on the draw/push rods in the oblique configuration thereof, imaginary extensions of the draw/push rods intersect at a point which lies approximately on the axis of rotation of the outward rotational movement of the running gear.Type: GrantFiled: June 25, 2013Date of Patent: May 2, 2017Assignee: Siemens AG OesterreichInventors: Christian Brandstaetter, Gerhard Kaserer, Christian Plankensteiner, Michael Sumnitsch
