Abstract
The invention relates to a railway vehicle chassis end structure which comprises an end beam, a traction beam and a corrugated floor. An unhooking protection device and a tripping prevention impact seat are arranged on the end beam, angle steel is arranged on the rear portion of the end beam and connected with the corrugated floor in a welded mode, a ribbed plate is welded to the portion between the end beam and the angle steel, connecting plates are further welded to protective cases of the unhooking protection device, and the connecting plates are welded to the traction beam. According to the railway vehicle chassis end structure, the angle steel splicing welding structure is adopted by the end beam, the relation between the end beam and a welding connector of the corrugated floor is optimized, and the situation that the corrugated floor structure is adopted by vestibules is achieved; the structure is simpler, and manufacture is convenient. By means of the novelly designed impact seat, the problem of interference with a diaphragm windshield frame can be solved, and the situation that a draw gear jump upwards and cracks up windshield aluminum profile can be effectively prevented. The unhooking protection device can effectively pulls a vehicle to a nearby maintenance point under the condition of unhooking.
Description
Technical field
The present invention relates to chassis of rail vehicle end construction, belong to chassis of rail vehicle design of terminations technical field.
Background technology
The intercity passenger vehicle operation of railway is frequent, and passenger capacity is large, is dredge one of main line and the most important instrument of branch line passenger.After entering 21st century, countries in the world continue to strengthen railway construction, bring unprecedented business opportunity to domestic passenger train outlet.But domestic existing structure cannot meet platform and the bounded qualification of external existing intercity circuit.Design and a kind ofly can meet existing line condition and the intercity passenger vehicle that load-carrying capacity is strong, safety is high effectively can improve intercity passenger vehicle efficiency of operation, alleviate travelling pressure.
Intercity passenger vehicle passenger capacity is large, and pillow is outer generally also adopts corrugated floor, to improve vertical stiffness, but consider that the interface relationship of corrugated floor and end carriage is generally by employing level land, platform place plate, be equipped with the structure of panting beam below, but similar structures relative complex, manufacturing process is relatively loaded down with trivial details.It is low to there is platform in external circuit, the possibility that hitch height is high, just causes the interface of domestic conventional striker and Tent folding windshield to be interfered.Therefore need redesign striker both to need to ensure the normal operation of hitch, ensure the aluminium section bar not breaking windscreen when hitch is jumped again.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of chassis of rail vehicle end construction.
In order to solve above technical matters, chassis of rail vehicle end construction provided by the invention, composition comprises: end carriage, draw beam and corrugated floor, it is characterized in that comprising: described end carriage is provided with unhook fender guard and anti-jump striker, described unhook fender guard has two protection boxs be symmetrically fixed on below end carriage, insert these two protection boxs respectively and resiliently mounted snubber chain bar, be connected to the chain hook on two snubber chain bars and chain link, the rear end of described snubber chain bar is rotary with nut, the front end of nut is provided with the stops be enclosed within snubber chain bar, snubber chain bar is also set with the spring that two ends prop up protection box front inner wall and this stops respectively, described end carriage rear portion is provided with angle steel, and angle steel and corrugated floor are welded to connect, and are welded with gusset between end carriage and angle steel, and the protection box of described unhook fender guard is also welded with connecting panel, and described connecting panel welds with draw beam.
The present invention also has following improvement:
1, the afterbody perforate of described snubber chain bar, is inserted with spring cotter in hole, to prevent nut loosening.
2, described end carriage leading flank is welded with two hooks, in not running at vehicle, tangle chain link and chain hook.
3, during vehicle operating, between the hook of Adjacent vehicles and chain link to extension connect, hitch once come off, by described hook and chain link transmitting tractive power.
4, described striker is arranged on end carriage by rivet.
5, the two ends of described end carriage are provided with corner, are provided with the landscaping sheet be connected with end carriage below corner.
Chassis of rail vehicle end construction of the present invention, is adopted the structure of angle steel welding, optimizes end carriage and corrugated floor welding junction relation, achieve the structure all being adopted corrugated floor by platform at end carriage place.This structure is relatively simple, easily manufactured.The striker of brand-new design is equipped with in the present invention, and striker is arranged on end carriage by rivet, can solve the problem of interfering with Tent folding windshield frame, can also effectively prevent from hitch is jumped filling bad windscreen aluminium section bar.Hitch unhook fender guard is also equipped with in the present invention; Foreign Existing travel permit part is poor; the conventional maintenance maintenance of vehicle cannot put in place; unhook accident may be there is; hitch unhook fender guard is housed, can when breaking off relations effectively towing vehicle arrive near maintenance point, unhook fender guard is welded on end carriage and connecting panel; connecting panel welds with draw beam, to strengthen whole fender guard intensity.
For meeting external gauge requirement, side bar adopts roll bending part, and this just needs the interface relationship designing brand-new end and side bar.Employing of the present invention and the similar corner of side bar and landscaping sheet, improve whole structure, landscaping sheet incorporates the interface with skirtboard, makes vehicular sideview present stream line pattern.
