REUSABLE COLLISION ENERGY ABSORPTION DEVICE FOR RAIL VEHICLE
A reusable collision energy absorption device for a rail vehicle includes an impacted rod, a damping structure including a damping plug, a guide tube and a damping elastic element, a return structure including a return piston and an elastic return element, an outer tube having a tubular structure, and an interior partitioned into a front cavity and a rear cavity through a partition plate provided with a damping hole in the form of a through hole. A portion of the damping plug is in the damping hole when the damping plug is in an initial position, and the damping plug can move in a front-rear direction when the device is impacted. A gap between a radial thickest portion of the damping plug and the damping hole allows the fluid to circulate between the front cavity and the rear cavity.

Multipart apron for a vehicle
An apron for a vehicle is formed of a plurality of partial aprons. In order to prevent damage to the apron requiring a complete replacement of the apron, the novel apron has a plurality of partial aprons, wherein at least one of the partial aprons has a predetermined breaking point that is configured to break earlier than the other partial apron in case of mechanical stress.

Easy-to-maintain frame-type energy-absorption structure
An easy-to-maintain frame-type energy-absorption structure, including: a fixing frame, anti-climder which are arranged at the front of the bottom of the fixing frame, energy absorption block which are detachably connected with the fixing frame and the anti-climder respectively, a connecting device for hinging the anti-climder and the fixing frame, and shear pins which are respectively arranged at a junction of the connecting device and the fixing frame, and a junction of the connecting device and the anti-climder. So that changing the traditional whole welded frame type energy absorbing device into an easy-to-maintain frame-type energy-absorption structure, and when a collision occurs, protecting the fixing frame from being damaged, and the energy absorption block can be replaced to achieve reuse it.
Personal protection device for fixing on the underside of a rail vehicle
An airbag module and a rail vehicle with an airbag module are described herein. The airbag module includes a support flap with a front end and a rear end. The rear end of the support flap is thereby pivotably mounted by means of a first pivot bearing, wherein the airbag module is convertible from a closed state into an open state by pivoting the support flap and the front end of the support flap thereby moves toward the track. The airbag module includes an airbag fixed on the airbag module. The airbag is folded in the closed state of the airbag module, and is unfolded in the open state of the airbag module. In its unfolded state, the airbag projects beyond the front end of the support flap, so that the unfolded airbag and the support flap together form an impact protection for a person on the track. Furthermore, a rail vehicle with one or a plurality of airbag modules is described.

Carbody of railcar
A carbody of a railcar includes: an underframe; a first member provided at one of vertical sides of a vertical center of the underframe, supported by the underframe, and absorbing collision energy; a second member provided at the other vertical side of the vertical center of the underframe, supported by the underframe, and contacting an obstacle when the first member is compressed by collision with the obstacle. In a case where the second member receives a reaction force from the obstacle when the first member is compressed by the collision with the obstacle, the second member transfers to the underframe a moment load that is opposite in a rotational direction to a moment load transferred to the underframe by the first member.
