Patent number: 6615671Abstract: A method for determining the fatigue strength of a corrodible connecting part between at least two structural parts, with the connecting part being subjected to specified corroding surroundings and a given repeated mechanical strain while being used. Diagrams (stress-number curves) that represents the variable of the repeated strain in relation to the number of strain repetitions until the destruction of the connecting part are used in order to determine the fatigue strength. First, a strain-free pre-corrosion of the connecting parts is carried out in a corrosive atmosphere corresponding to the corrosive atmosphere during the intended use of the part, in a time period after which the duration of the pre-corrosion has hardly any influence on the shape of a stress-number curve that is recorded subsequently.Type: GrantFiled: January 28, 2002Date of Patent: September 9, 2003Assignee: DaimlerChrysler Rail Systems GmbHInventors: Hartmut Carstensen, Reinhard Knödler, Rainer Franke

Patent number: 6556914Abstract: A semiautomatic control system or control method ensures a driving method which is as energy-saving as possible. In the system, there is both a) manual inputting of control data, for example a definition of a vehicle speed specified value, by the driver of the vehicle and b) automatic determination of the most energy-saving vehicle speed as a function of predefined peripheral conditions, for example a general travel schedule, the topology of a route, vehicle-specific peripheral conditions and the like. An inference system determines which of these two values is smaller, and the smaller value is used to make possible safe and at the same time energy-saving travel (or journey). A safety check of the manual travel speed input value and of the automatically determined travel speed specified value can also be performed to reliably prevent a maximum permissible travel speed value from being exceeded.Type: GrantFiled: April 12, 2001Date of Patent: April 29, 2003Assignee: DaimlerChrysler Rail Systems GmbHInventors: Ueli Nievergelt, Rüdiger Franke

Patent number: 6474455Abstract: A current collector is located on a roof cover plate of a car body for a rail vehicle. Mounted on said current collector is an intermediate carrier for a current collector frame which is equipped with two wearing strips. Said intermediate carrier is suspended on oscillating rods. According to the invention, the intermediate carrier is configured in the form of a thin plate so that in its resting position, i.e. in its lowered position, the current collector, including wearing strips, is located within the regulation limitation line of the vehicle. In this way, the construction height is reduced.Type: GrantFiled: May 4, 2001Date of Patent: November 5, 2002Assignee: Daimlerchrysler Rail Systems GmbHInventors: René Blaschko, Stefan Pahnke

Patent number: 6431083Abstract: The subject matter of the invention is a rail vehicle with a head module made of a composite fiber material. For this, a joining region with height-tolerance compensating means (5) is arranged on the underframe (3) and a joining edge with longitudinal and lateral tolerance compensating means (7 and 8) is arranged on the wagon body module (2). The head module has joining edges that point toward the wagon body module (2) and the underframe (3) and is provided with reinforced sections (18, 19) that are integrated into the fiber composite material. The head module is attached to the underframe (3) and at least at the head module side walls (14) of the wagon body module (2) by means of fastening means (20, 21), which build up a pre-tensioning force, in such a way that shear-resistant connections are created.Type: GrantFiled: August 8, 2000Date of Patent: August 13, 2002Assignee: DaimlerChrysler Rail Systems GmbHInventors: Hartmut Carstensen, Bernd Hoppe, Ursula Wagner, Burkhart Liesenberg, Erwin Schmelzer

Patent number: 6418397Abstract: An improved device for measuring the contact force between a contact wire and a power collector in an electrically powered vehicle, specially an electrical railway vehicle, by use of optical fiber force sensors. To this end, two compact force sensors are arranged between the base body (7) of the contact strip (6) and the pantograph rocker frame (5) or between the wearing element or shoe (8) and the base body (7) of the contact strip (6). Each sensor includes a deformable body (11), which is elastic in an axial direction but highly rigid crosswise, with the body being fitted with an integrated optical fuber reflex sensor (19). Axial deformations of the deformable body (11) equivalent to the contact force are detected by the reflex sensor (19) with high resolution, accuracy and no interference, are then signaled to a device (27) via optical fibers requiring no potential and converted therein into contact force-equivalent signals (28) or instructions (29).Type: GrantFiled: February 2, 2000Date of Patent: July 9, 2002Assignee: DaimlerChrysler Rail Systems GmbHInventors: Werner Brand, René Blaschko, Olaf Mollenhauer, Andreas Karguth

Patent number: 6393344Abstract: Interference currents in railway trackside signaling apparatus are monitored by first and second transducers adapted to measure the traction current and frequency, respectively, of power electronics in traction systems of railway vehicles. An instantaneous interference current value is determined, based on data output from the first transducer. Data output from the second transducer is used to determine digital filter outputs for the trackside signaling frequencies for the interference current value. The determined interference current value and digital filter output values are recorded on a data storage medium and displayed on a display unit.Type: GrantFiled: December 7, 2000Date of Patent: May 21, 2002Assignee: DaimlerChrysler Rail Systems GmbHInventors: Douglas Eastman, Glyn Orchard, Chris Bates

Patent number: 6236131Abstract: An improved, multi-strand design of a transverse flux machine with unilateral stator and rotor, with essentially U-shaped yokes (6) and I-shaped yokes (3) in the stator, as well as a rotor with permanent magnets (5) that are attached planar and a circular back iron (4). The bending of the U-shaped yokes (6) at a right angle results in a considerable reduction of the leakage paths. A joint use of the stator yoke by several strands results in a considerable increase in the torque density, as compared to known embodiments. The direct cooling of winding and stator iron makes it possible to have a machine design with considerably reduced eddy current losses.Type: GrantFiled: March 29, 2000Date of Patent: May 22, 2001Assignee: DaimlerChrysler Rail Systems GmbHInventor: Uwe Schafer
