Abstract

A chassis end plate assembly of a railway vehicle is provided, which includes an end plate; a bottom beam arranged at an inner side of a lower edge of the end plate, curved beams arranged at inner sides of two sides of the end plate, a buffer beam located above the end plate; and a reinforcing beam longitudinally arranged between the buffer beam and the bottom beam. The end plate assembly can increase the rigidity of an end portion of the vehicle and improve the vibration mode. The end plate assembly can be combined with an under-vehicle active device compartment so as to form an enclosed space, which may protect pipelines and devices under the vehicle. A railway vehicle provided with the chassis end plate assembly is further provided.

First claim

What is claimed is:

1. A chassis end plate assembly of a railway vehicle, comprising:
an end plate, which is a hollow profile with double layers and has the same outline as a cross-section of an under-vehicle active device compartment;
a bottom beam arranged at an inner side of a lower edge of the end plate;
curved beams arranged at inner sides of two sides of the end plate respectively;
a buffer beam located above the end plate; and
a reinforcing beam longitudinally arranged between the buffer beam and the bottom beam;
wherein outer surfaces of the buffer beam and the end plate are located in the same plane, the buffer beam has a left half part and a right half part which are left-right symmetric, and between the two half parts, a U-shaped groove configured to accommodate a coupler is provided, vehicle-end damper mounting grooves having outward openings are provided at two sides of the buffer beam, and the left half part and the right half part are each provided with a mounting hole configured to allow pipelines or wirings to pass through.

2. The chassis end plate assembly of a railway vehicle according to claim 1 , wherein each of the curved beams comprises a first curved beam and a second curved beam, the first curved beam is located at an inner side of an arc edge of the end plate, and the first curved beam is transitionally connected to the bottom beam via the second curved beam.

3. The chassis end plate assembly of a railway vehicle according to claim 1 , further comprising a lining plate circumferentially arranged at inner sides, of the bottom beam, the curved beams and the buffer beam.

4. The chassis end plate assembly of a railway vehicle according to claim 1 , wherein an upper edge of the buffer beam is bent inward by 90 degrees and then is continuously bent downward and inward by 90 degrees, and forms a Z shape; and a lower edge of the buffer beam is bent inward by 90 degrees.

5. The chassis end plate assembly of a railway vehicle according to claim 4 , wherein horizontal wing plates parallel to each other are provided between the upper edge and the lower edge of the buffer beam; each of the wing plates comprises a first wing plate and a second wing plate, the first wing plate is located in the same plane as an upper edge of the vehicle-end damper mounting groove, the second wing plate is located below the first wing plate and is shorter and narrower than the first wing plate, and the second wing plates are located at two sides of the U-shaped groove.

6. The chassis end plate assembly of a railway vehicle according to claim 5 , wherein a longitudinal wing plate is arranged on a top of the buffer beam.

7. The chassis end plate assembly of a railway vehicle according to claim 5 , wherein the mounting hole comprises a first mounting hole above the first wing plate, and a second mounting hole and a third mounting hole which are both located below the first wing plate and at an outer side of the second wing plate.

8. The chassis end plate assembly of a railway vehicle according to claim 1 , wherein the end plate and the buffer beam are each provided with an inner windshield mounting interface, and the end plate is further provided with an outer windshield mounting interface.

9. The chassis end plate assembly of a railway vehicle according to claim 1 , wherein the bottom beam and the curved beam are hollow rectangular profiles, and on a side of each of the bottom beam and the curved beam abutting against the under-vehicle active device compartment, a vertical edge deflecting toward an interior of a vehicle body is formed.

10. A railway vehicle, comprising a vehicle body and a bogie, wherein an under-vehicle active device compartment of the vehicle body is provided with the chassis end plate assembly of a railway vehicle according to claim 1 , and a part below the buffer beam of the end plate assembly is combined with the under-vehicle active device compartment to form an enclosed space.
