Abstract
The utility model provides an underframe of a motor train unit locomotive, a locomotive and a bullet train. A sand box groove is formed on the front end of the underframe in an integrated mode. A cover of the sand box is fixed on the sand box groove. Adopting the underframe of a motor train unit locomotive, the sand box groove is directly formed on the front end of the underframe. As part of the underframe, the sand box groove is involved in the underframe bearers, and therefore the external load received by the underframe can be reduced.
Description
Technical field
The utility model relates to the physical construction technology, relates in particular to the automobile-used underframe of a kind of motor train unit head, a car and motor train unit.
Background technology
Sandbox is one of requisite parts on the EMU, and sandbox is used for the storage sand.Under compressed-air actuated effect, the sand in the sandbox is blown on the rail, to increase the sticking action power between wheel and the track.Sandbox comprises casing, and is opened in sand inlet and sand export on the casing.Sandbox independently arranges, and is suspended on the underframe front end of motor train unit head car.
There is following problem at least in prior art: sandbox independently arranges, and the underframe front end that sandbox is suspended on motor train unit head car can increase the load that underframe bears.
The utility model content
The utility model provides the automobile-used underframe of a kind of motor train unit head, a car and motor train unit, is used for reducing the load that underframe bears.
The utility model provides a kind of motor train unit head automobile-used underframe, and wherein, described underframe front end is formed with the sandbox groove, is fixed with sand box cover on the described sandbox groove.
Aforesaid underframe, preferably, described underframe front end both sides respectively are formed with a sandbox groove, are fixed with sand box cover on each described sandbox groove.
Aforesaid underframe, preferably, described sand box cover is welded on the described sandbox groove.
Aforesaid underframe, preferably,
Offer sand inlet and sand export on the described sand box cover, wherein, be in the use state, described sand inlet is positioned at the top of described sand box cover, and described sand export is positioned at the below of described sand box cover.
Aforesaid underframe, preferably,
Offer observation port on the described sand box cover, the outer side seal of described observation port is provided with clear sheet.
The utility model embodiment also provides a kind of car, wherein, comprises the underframe that the utility model provides arbitrarily.
The utility model embodiment provides a kind of motor train unit again, wherein, comprises the car that the utility model provides arbitrarily.
The automobile-used underframe of motor train unit head that technique scheme provides is formed directly into the underframe front end with the sandbox groove, and the sandbox groove participates in the underframe carrying, therefore can reduce the external load that underframe is subject to as the part of underframe.
Description of drawings
The automobile-used underframe local structure of the motor train unit head schematic diagram that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the decomposition texture schematic diagram of Fig. 1 cheek groove and sand box cover;
Fig. 3 is the local structure schematic diagram of Fig. 1 cheek groove.
The specific embodiment
Referring to Fig. 1-Fig. 3, the utility model embodiment provides a kind of motor train unit head automobile-used underframe 1, and wherein, described underframe 1 front end is formed with sandbox groove 2, is fixed with sand box cover 3 on the described sandbox groove 2.
Herein, the outer rim of sandbox groove is curved, the outer rim form fit of the shape of sand box cover and sandbox groove.Being arranged to arc is in order to mate with a car monnolithic case.
Referring to Fig. 1, in the practical application, rail has two, and for the ease of stucco on each rail, underframe front end both sides respectively are formed with a sandbox groove 2, is fixed with sand box cover 3 on each described sandbox groove 2.
The automobile-used underframe of motor train unit head that technique scheme provides is formed directly into the underframe front end with the sandbox groove, and the sandbox groove participates in the underframe carrying, therefore can reduce the external load that underframe is subject to as the part of underframe.
Further, described sand box cover 3 is welded on the described sandbox groove 2.After being welded and fixed, sand box cover 3 also can bear the carrying that underframe 1 is subject to, and also can reduce space under the car that sandbox takies.
This time, referring to Fig. 1, offer sand inlet 33 and sand export 31 on the described sand box cover 3, wherein, be in the use state, described sand inlet 33 is positioned at the top of described sand box cover 3, and described sand export 32 is positioned at the below of described sand box cover 3.
The sand inlet of above-mentioned set-up mode and sand export are convenient to the turnover of sand, for ease of operation, sand inlet can also be arranged on the position that the sand box cover top is positioned at the side.
Amount for the ease of sand in the observation sandbox also can offer observation port 32 on the sand box cover 3, and described observation port 32 outer side seals are provided with clear sheet.
The automobile-used underframe of motor train unit head that technique scheme provides can participate in the car body integrated carrying, has fully improved the degree of utilization of material, and above-mentioned underframe is widely used in the CRH3 motor train unit car body design.During the car body test of static strength, at hitch zone clamp load 1500kN+ vertical load m1+m2, braking sandbox and do not finding the point that stress exceeds standard on every side, as seen its intensity satisfies the requirement of car body test of static strength.In addition, compare with the independent sandbox with the fastener installation of making in the prior art, technique scheme also can reduce the use and maintenance cost of sandbox.
The utility model embodiment also provides a kind of car, wherein, comprises the underframe that the utility model any embodiment provides.
In the technique scheme, have the underframe that forms the sandbox groove on the car, can avoid using the independent sandbox that arranges, reduce the load that underframe is subject to.
The utility model embodiment provides a kind of motor train unit again, wherein, comprises the car that the utility model any embodiment provides.
The motor train unit that technique scheme provides can reduce the load that underframe is subject to.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
