20090133601 | Electronic Pneumatic Spring Controller for Reducing Air Consumption and Rapidly Adjusting the Setpoint Level - Disclosed is a railway vehicle comprising at least one pneumatic spring for supporting a body. At least one mechanically actuated valve is disposed in at least one air supply/discharge tube of the at least one pneumatic spring in order to control air exchange of the at least one pneumatic spring. At least one switching means is provided between the at least one mechanical valve and the at least one pneumatic spring in the at least one air supply/discharge tube in order to control air exchange. Alternatively, at least one switching means is arranged between the at least one mechanical valve and at least one pressure source while at least one additional switching means is placed in a tube that connects the at least one mechanical valve to an environment in order to control air exchange. | 05-28-2009 |
20110248433 | Primary Spring - A primary spring for chassis of rail vehicles is provided. The spring is designed as a substantially rectangular layered spring that is fitted into a bearing housing. | 10-13-2011 |
20120046830 | Method for Controlling a Pneumatic Spring Assembly of a Motor Vehicle - The invention relates to a method for controlling a pneumatic spring assembly of a motor vehicle, wherein discrete condition parameters are derived from the condition of the motor vehicle and combined into parameter sets, wherein each parameter set is furthermore associated with a defined height control behavior, and wherein a height control behavior that is associated with a specific condition of the vehicle is set by appropriately activating at least one valve of the pneumatic spring assembly. | 02-23-2012 |
20120111675 | Brake Carrier For The Bogies Of Rail Vehicles - A brake carrier for bogies of rail vehicles has an open cross-section with flexible torsion. A connection to two longitudinal members of the bogie is designed as a rigid non-articulated connection and a braking device is fixed to the brake carrier in such a way that a line of action of braking forces runs through the shear centre that lies outside the cross-section of the brake carrier. | 05-10-2012 |
20120180693 | Roll compensation system for rail vehicles - A rocking compensation system for rail vehicles includes actuators which are arranged within primary helical compression springs of bogies for a targeted height adjustment of a bogie frame of the bogie. | 07-19-2012 |
20120240813 | CHASSIS FRAME FOR RAIL VEHICLES - A chassis frame for rail vehicles includes two longitudinal beams and at least one transverse beam which is disposed between the longitudinal beams and hinged thereto. The longitudinal beams are designed in a bent shape and extend through a corresponding cutout of the transverse beam. | 09-27-2012 |
20130019775 | RAIL VEHICLE WITH VARIABLE AXIAL GEOMETRY - A rail vehicle with variable axial geometry includes at least two axles, wherein a horizontal angular position of each axle with respect to the vehicle frame may be changed, and wherein the angular position of each axle is adjusted continuously during operation of the rail vehicle in such a way that a predefined lateral displacement and a predefined axial angle are achieved. | 01-24-2013 |
