摘要： A device for spreading granulate, particularly for spreading sand into the gap between a rail and a wheel of a rail vehicle, includes a housing, at least one inlet for the granulate and at least one outlet for the granulate, an axially movable metering piston and a compressed air connection, which leads into a pressure chamber and serves for actuating the metering piston by compressed air to meter the granulate. At least one bore is provided in the metering piston. To create a device which is of particularly simple and compact construction, a conveying air chamber separated from the pressure chamber and has a compressed air connection is provided, and at least one bore in the metering piston connects the conveying air chamber to the at least one outlet for the granulate, such that granulate can be conveyed to the at least one outlet by compressed air independently of the metering process.

摘要： A system and method for reducing the threat of derailment of a train during deceleration is provided. An individualized braking force for each rail car of a train, such individualized braking force being determined by the braking deceleration of the train's locomotive, may be calculated by the rail car's controller and is directly proportional to the mass of the rail car. The controller may utilize the various forces acting upon the individual rail car as measured by a plurality of sensing and measuring devices to dynamically adjust the braking force applied to the individual rail car's brakes. Such a system and method allows for the train to act as a single body mass when decelerating to eliminate rail car pile-up and reduce the threat of derailment.

摘要： A method for operating a tractive vehicle and a vehicle combination are disclosed. A tractive vehicle includes a first friction brake device for generating a first stopping braking-force, a traction device for generating a tractive force and a control device for controlling at least the traction device. The method includes a step whereby the traction device is activated if a first undesired kinematic state is detected. Activation of the traction device would take place in such a way that a tractive force, counteracting the first undesired kinematic state, is generated and provided for deceleration to a standstill and/or for holding the tractive vehicle at a standstill.

摘要： A superconducting magnet for eddy-current braking for a high-speed train. The superconducting magnet is fixed at a bottom of a bogie of the high-speed train through a connecting mechanism, and an air gap is formed between the superconducting magnet and a top of a guide rail below the bogie. The superconducting magnet after being excited generates an eddy-current effect with the guide rail of the high-speed train, so as to generate a braking force opposite to a traveling direction of the train, thereby braking the high-speed train. A liquid-level meter is provided on the superconducting magnet to detect a position of a cooling agent liquid level in real time. The superconducting magnet withstands vibration impact through elastic tie rod assemblies when the high-speed train is under operation, showing good adaptability.

摘要： A branch pipe tee for a rail car having a length that is below standard. The branch pipe tee has a standard mount for connecting to the brake pipe and branch pipe as well as integral volume that compensates for the reduced brake pipe length of the rail car. The integral volume is dimensioned to make the effective brake pipe length of rail car fall within standard ranges so that the braking system of the rail car can perform normally and avoid the need for additional equipment to compensate for the length of the rail car.

摘要： A wheel slip control system employs a method of varying the detection and correction parameters it uses based on whether the wheel/axle combinations on a truck of a rail vehicle operate in the coupled or decoupled modes of operation. The control system executes programming code featuring detection and correction logic. The steps of the method include deriving both detection parameters optimized for each mode called coupled and decoupled detection parameters and correction parameters optimized for each mode called coupled and decoupled correction parameters. Another step involves monitoring the amount of dynamic braking applied to the wheel/axle combinations. Yet another step involves determining whether the amount of dynamic braking lies for a preset time period within a preset zone of operation for the dynamic braking of the wheel/axle combinations on the truck. The method provides the coupled detection parameters to the detection logic if the amount of dynamic braking lies within the preset zone for the preset time. Alternately, it provides the decoupled detection parameters to the detection logic if the amount of dynamic braking fails to lie within the preset zone for the preset time. The method provides the coupled correction parameters to the correction logic if the amount of dynamic braking lies within the preset zone for the preset time. Alternately, it provides the decoupled correction parameters to the correction logic only if the amount of dynamic braking fails to lie within the preset zone for the preset time when the wheel slip control system is inactive.
