A central traction device for a straddling monorail train includes a traction pin and a traction beam. A central sleeve is provided at the center of the traction beam, and the traction pin is mounted in the central sleeve. An inner cavity of the central sleeve has a corset-shaped structure having large diameters on an upper end and a lower end and a small diameter at a middle part, forming double tapered bevels, and a resilient rubber bush is provided between an inner wall of the central sleeve and the traction pin. The device has a simple and compact overall structure and facilitates connection and separation between the train body and the bogie; by providing the lift assembly, the traction device is fixedly connected to the frame, thus the traction device can be wholly lifted; and operation process and environment of raising and lowering the vehicle are improved.

A draft gear assembly for use with railcars having coupler members is provided. The draft gear assembly has front and back ends and comprises a yoke, a coupler follower, a front resilient member, an intermediate stop member, and a back resilient member. The yoke has a back wall, a top wall extending from the back wall toward the front end of the draft gear assembly, and a bottom wall extending from the back wall toward the front end of the draft gear assembly. The coupler follower is positioned between the butt end of the coupler shank and the front end of the draft gear assembly. The front resilient member is positioned between the coupler follower and the intermediate stop member. The back resilient member is positioned between the intermediate stop member and the yoke back wall. The front and back resilient members are compressible.

A rail vehicle has a bogie which rolls on a track in a direction of travel, a vehicle structure which is supported on the bogie, a rigid carrying structure which is arranged on the end side of the rail vehicle, and an end-side coupling opening through which a coupling extends for coupling further rail vehicles. A coupling securing device secures the coupling to the rail vehicle. The coupling securing device has reversible securing elements which permit a reversible lifting movement counter to the direction of travel to such an extent that the coupling is retracted completely into the supporting structure. As a result of the retraction of the coupling into the cage-like carrying structure it no longer influences the crash behavior.

A shock-absorbing device comprises a hollow housing with a closed end section and an opposing open end section through which a main axis passes, a resilient system disposed in a bottom section of the housing, a pressing element, and a friction system disposed in the open section of the housing. The resilient system is formed by a dynamic load absorber located in the closed part of the housing along the main axis of the housing on the guide bar. The guide bar has a head for installation thereof in a recess formed in the closed bottom section of the housing for centering the guide bar relative to the main axis. All structural components of the friction system and the resilient system are provided and arranged such that the working stroke of the shock-absorbing device is from 110 to 120 mm.
