摘要： The present invention relates to a train coupler adapted for energy absorption by the use of a deformation unit. According to the invention an axial expansion module is provided and mounted together with the deformation unit and an anchor in the housing of the train coupler. By expanding the axial expansion module after being mounted into the housing, the deformation unit and the anchor will be biased between the front and rear lugs of the housing and held in place by a predetermined force in the axial direction only.

摘要： There is provided a method for detecting failure of a gas-hydraulic damper for a rail vehicle, comprising: - receiving a first input signal (S1) indicative of a stroke related parameter of the gas-hydraulic damper determined at a first time instance, - determining a first stroke value, based on the first input signal (S1), - receiving, at least one second input signal (Si), wherein each subsequent signal (Si) is indicative of a respective stroke related parameter measured at a respective subsequent time instance, - determining a respective stroke value based on each of the second input signals (Si), - determining a stroke value over time based on the determined stroke values, and - determining that there is a failure of the gas-hydraulic damper if the stroke value over time, fulfils a first criterion. Also provided are a system, a gas-hydraulic damper and computer program product.

摘要： The invention relates to an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle, comprising a plug that has a longitudinal axis and a mandrel that has an opening, whereby the plug is arranged to be moved at least partially through the opening, if a force pointing in the longitudinal axis is applied to the plug, and whereby at least a part of the plug—especially its hull—is deformed, when the plug is at least partially moved through the opening, whereby said hull being at least partially deformed, when the plug is at least partially moved through the opening. The hull is attached to the rod by clamping or fixing with fasteners, preferably with protrusions around the rod and/or at least one plug or nut. The hull is a relatively independent element which can be put over a rod and therefore the hull can be mounted or unmounted subsequently to a rod without influencing the stability or main function of the connection device.

摘要： An energy dissipating device includes a guide defining a guide surface having a curved cross-section. A deformer is slideably supported by the guide surface of the guide in a compression stroke direction of the device. A stopper is fixedly attached to the device and arranged at a distance from the deformer in the compression stroke direction. An energy dissipating member is arranged between the stopper and the deformer in the compression stroke direction, and includes a first end configured to engage with the stopper and a second end configured to engage with the deformer in response to a force thereon in the compression stroke direction.
