Provided is a rail car that is capable of efficiently transmitting vibrational forces that have been transmitted from a bogie via a yaw damper and a yaw damper support to an underframe to a rail car shell, and that is of a simple structure, sufficient mechanical strength, and light weight for reducing the amount of heat applied to perform welding and for allowing a nondestructive inspection to be performed with ease. The rail car includes a rail car shell, a bogie that supports the rail car shell, a yaw damper having an end connected to the bogie, and a yaw damper support to which another end of the yaw damper is connected. The rail car shell includes an underframe including a floor assembly providing a floor and a bolster beam joined to the floor assembly, and a pair of side structures erected at both transverse ends of the underframe. In this rail car, the yaw damper support is fixed to a transverse end of the bolster beam.

Provided is a rail vehicle that efficiently transmits, to a railway vehicle structure, an oscillating force transmitted from a bogie to an underframe via a yaw damper and a yaw damper support portion, and that has sufficient strength. The underframe includes a floor portion, a side beam, and a bolster beam. A side structure is erected on an end portion in a vehicle width direction of the underframe. The bogie supports the underframe from below the underframe. A yaw damper receiving portion is provided to the end portion in the vehicle width direction of the underframe. The yaw damper support portion is fixed to the yaw damper receiving portion. The yaw damper includes one end portion connected to the bogie and the other end portion connected to the yaw damper support portion. The yaw damper is configured to reduce yawing oscillation of the bogie. The yaw damper receiving portion is provided to extend along the side structure, the side beam, and the bolster beam.

The invention discloses a method and a system for controlling yaw damper disconnection. In one embodiment of the invention, a turn-off pre-position signal is generated when the rudder, the yaw damper data transmission path, and / or the primary flight control system operate abnormally, and in response to the turn-off pre-position signal, the yaw damper is turned off if it is determined that at least one of the rudder control link or the yaw function of the rudder is abnormal.

Provided is a rail vehicle which has adequate strength and in which an excitation force being transmitted from a railcar truck to an underframe via Yaw dampers and yaw damper supports can be efficient

The utility model relates to the field of disassembly and assembly of dampers, in particular to an auxiliary disassembly and assembly device for a centering spring rod of a yaw damper, which comprises a placing plate, a disassembly and assembly main body, two convex plates with the same specification, a fixed jaw, a connecting plate, a clamping jaw, a clamping plate, a screw rod, a rotating head and a bearing, the disassembly and assembly main body is arranged on the upper side of the placing plate, and the two convex plates with the same specification are arranged at the lower end of the side surface of the disassembly and assembly main body; a connecting plate is installed at the upper end of the side face of the disassembling and assembling body, a clamping jaw is installed on the side face of the connecting plate, a clamping plate is installed on the clamping jaw, and through the clamping effect of the fixing jaw, the clamping jaw and the clamping plate, the locking function is achieved, the disassembling and assembling process is simplified, and operation is easier and more convenient; the rotating handle is installed on the side face of the rotating head, the adjusting function is achieved by rotating the rotating handle, operation is easy and safe, the working efficiency can be remarkably improved, and bearings are installed on the upper side and the lower side of the screw.

A rail car 1 comprising a rail car shell including an underframe 10 including a floor assembly providing a floor and a bolster beam 13 joined to the floor assembly, and a pair of side structures erected at both transverse ends of the underframe. The rail car further comprises a bogie that supports the rail car shell, a yaw damper 8 having an end connected to the bogie, and a yaw damper support 17 to which another end of the yaw damper is connected, wherein the yaw damper support is fixed to a transverse end of the bolster beam. The bolster beam may be larger in the transverse dimension than the floor assembly. The bolster beam may include a horizontal assembly that is held against a lower surface of the floor assembly, and a protrusive assembly that protrudes upwardly from a transverse end of the horizontal assembly. The transverse end of the horizontal assembly and the protrusive assembly are integrally extrusion-moulded along a longitudinal direction of the rail car as a hollow extrusion-moulded structure. The protrusive assembly may be joined to a lower end of each of the side structures.
