摘要： A bogie of a rail vehicle includes a frame, which includes two box-shaped longitudinal beam main bodies and a transverse beam main body; a wheelset, which includes an axle box, an axle and wheels mounted at two ends of the axle; a drive system, which at least includes a gearbox and a drive motor. Practice has proved that the two axle boxes arranged on the inner sides of the two longitudinal beam main bodies can reduce a volume by about 10%, and reduce a weight by about 10% to 15%, which can further reduce air resistance, and realize energy saving and emission reduction. The longitudinal beam main body is located on an inner side of a wheel, a span of the two the longitudinal beam main bodies is reduced, and the torsional rigidity of the frame is reduced, which is beneficial to improving a curve passing capacity.

摘要： A drive includes at least one motor with a drive shaft and at least one output shaft which is in particular mechanically connected to a gear. The drive shaft and the output shaft are aligned substantially axially. The drive shaft and the output shaft each have a coupling portion through which a torque can be transmitted from the drive shaft to the output shaft by mechanical coupling. Each coupling portion is connected to the shaft thereof for rotation therewith and the coupling portions can be mechanically coupled by being axially plugged together.

摘要： A railcar bogie includes a bogie frame including a cross beam and supports, the supports disposed at respective car width direction end portions of the cross beam. There are a plurality of axle boxes to accommodate a plurality of bearings supporting a pair of axles, a plate spring extending in a car longitudinal direction and supported by a pair of the axle boxes which are away from each other in the car longitudinal direction among the plurality of axle boxes. The plate spring supports the cross beam while being pressed by the corresponding support from above such that the pressing member is separable from the plate spring. Elastic walls are at both respective sides of the supports in the car longitudinal direction and sandwiched between a lower surface of the bogie frame and an upper surface of the plate spring so as to be compressed.

摘要： The present disclosure relates to a track travelling device, comprising a vehicle body, a connection device and two groups of wheels. The two groups of wheels are disposed on two sides of the vehicle body respectively and the wheels comprise rims matched with tracks. One end of the connection device is connected to a bottom of the vehicle body and the other end of the connection device is connected to the wheels. The connection device comprises an elastic member and the elastic member is configured to be deformed under the gravity of the vehicle body to adjust distances between the rims of the two groups of wheels. Under the gravity of the vehicle body, the track travelling device of the present disclosure can closely attach the rims of the wheels to side surfaces of the tracks, thereby preventing the vehicle body from swaying side to side. Meanwhile, the connection device comprises the elastic member for adaption to a change of a track gauge.

摘要： A device for connecting a cross member for receiving pivot pins on two lower longitudinal members of a car body for a rail vehicle. The cross member has a transversal part that connects the two longitudinal members to each other in the region of the connection, and a longitudinal part that extends to the closest car front. The lower longitudinal members extend over the complete length of the car body and consist of multi-chamber hollow profiles made of a fibre composite material. The number of chambers of the multi-chamber hollow profile of each longitudinal member is reduced in the region of the connection such that the wall material of at least one chamber was removed in such a way that the webs to the adjacent chambers are exposed. At these places, load-introducing elements engage, to which load-introducing elements the cross member is attached.
