The invention relates to bogies for railway vehicles with at least two wheelsets mounted in axleboxes and at least one transverse member. The bogies are in particular characterized in that they have a lightweight design and can be produced at low cost. The axleboxes of a wheelset are articulated to the transverse member via two axle levers so that the axle levers form an H shape with the axleboxes and the transverse member. The transverse member has at least two torsion bars arranged in parallel to the axles of the wheelsets, said torsion bars being firmly connected to the transverse member. The torsion bars have spring levers so that the end portion of the spring lever not connected to the torsion bar acts upon the axlebox.

A method, system and device for controlling a door of a railway vehicle are provided. The method comprises: a door control instruction sent by a transponder is received when a railway vehicle draws into the station, wherein the door control instruction is used for determining a door of the railway vehicle at a platform side; and the railway vehicle is controlled to open the door of the railway vehicle at the platform side according to the door control instruction, thereby solving the technical problem that the door of a railway vehicle at the non-platform side may be opened by mistake by a driver due to human factors because the door of the railway vehicle at the platform side is manually opened when the railway vehicle stops.

A mold with cavities for nanoimprint lithography and a method of imprinting the same. The mold is a one-piece structure, including an upper mold and a lower mold which are welded together. The upper mold is evenly provided with a plurality of stepped holes. A plurality of grooves are provided at an upper surface of the lower mold. Both ends of each groove are respectively connected to an external high-pressure water pump and an external vacuum pump via pipelines. An airtight cavity is additionally provided at the interior of the mold to form a negative pressure in the cavity by vacuumizing during the imprint process. In the demolding, a crack is formed at the interface between the mold and the imprint resist by using water pressure and expands to the entire interface for the demolding of the imprinted structure.

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 mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.
