The present invention relates to a fender, bogie, train, track and methods. The fender according to the invention comprises: a support surface provided on the underside during use; an inner pressure chamber provided in or on the support surface; a feed arranged in the pressure chamber for feeding a fluid; a first rim present round the inner pressure chamber, wherein at least a part of the rim is flexible; and a second rim arranged round the first rim such that a pressure chamber is created between two adjacent rims.

A telescopic type collision energy absorption device includes a first tube, a second tube telescoped within the first tube, and a telescopic mechanism connected with the second tube by passing through the first tube, the first tube being mounted with a cutting mechanism for cutting an outer wall of the second tube, when the device is in a non-operating state, the telescopic mechanism pulls the second tube to retract into the first tube; in a state prior to the collision of a vehicle, the telescopic mechanism under an effect of high-pressure air pushes the second tube to eject outwards, the cutting mechanism is pressed against locating slots of the second tube under an effect of a spring force, the cutting mechanism cuts the second tube and absorbs energy when the second tube is subjected to an external force and retracts towards interior of the first tube.

A method for turning robots at an intersection of tracks. The robot moves in a first motion mode to reach a first position at the intersection. The robot turns over a corner of the intersection that includes continuous tracks connecting a vertical track and a horizontal track, whereby reaching a second position at the intersection. The robot moves in a second motion mode towards a designated direction.

A suspension system for a railway vehicle includes a hub assembly configured to travel along a track, a suspension element coupled to the hub assembly and configured to provide a suspension force, a regulator coupled to the suspension element and configured to selectively adjust the suspension element, and a processing circuit. The processing circuit is configured to determine a target configuration for the suspension element using a characteristic of the track at a target position, the target position selected based on a location of the railway vehicle, and engage the regulator based on the target configuration such that the suspension force applied by the suspension element is based on the location of the railway vehicle and the characteristic of the track.

A method detects a defect in an acceleration sensor. In order to be able to reliably detect a defect in an acceleration sensor, the acceleration sensor generates a signal which is checked during a test as to whether a variable dependent on the signal fulfills a predefined condition with respect to a reference value and, on the basis of the test, it is determined whether the acceleration sensor is defective.

A fluororubber composition comprising 10 to 50 parts by weight of wollastonite and 0.5 to 10 parts by weight of organic peroxide based on 100 parts by weight of peroxide-crosslinkable fluororubber, the wollastonite being needle-like or fibrous wollastonite having an average fiber diameter of 5 m or less and an average fiber length of 40 to 80 m, and the wollastonite being surface-treated with an amino silane coupling agent or an epoxy silane coupling agent. The fluororubber composition that can be suitably used as, for example, a molding material for normal/reverse rotation oil seals that allow continuous excellent sealing of fluid in the operation of normal and reverse rotation.

A vehicle, in particular a rail vehicle, includes a compressed-air-operated toilet device and a compressed air supply system which supplies compressed air to the toilet device during normal operation. The vehicle also includes an emergency compressed air source that is suitable for providing compressed air for continued operation of the toilet device in the event of a failure of the compressed air supply system.
