Abstract
The utility model discloses a chassis structure of a rail engineering vehicle. To meet the mounting space requirement of equipment of the rail engineering vehicle and improve the strength and the rigidity of the chassis structure, the chassis structure comprises a chassis beam body framework, wherein the chassis beam body framework is mainly formed by connecting a traction beam, boundary beams, sleeper beams, longitudinal beams and transverse beams. An embedded chassis floor is installed in the chassis beam body framework, and the horizontal height of the upper surface of the chassis floor is smaller than the horizontal height of the upper surface of each boundary beam. The chassis structure of the rail engineering vehicle is reasonable and reliable in structure; on the premise that the locomotive limit requirement is guaranteed, the space of a cab and the space of a machinery room are expanded, the mounting space requirement of equipment is guaranteed, and safety running can be guaranteed easily.
Description
Technical field
The utility model relates to a kind of rail engineering automobile Undercarriage structure.
Background technology
Underframe, as the main carrying structure of car body, not only bears the quality of car body itself and the quality of Che Nei all devices, goes back transmitting tractive power and braking force and complicated dynamic stress simultaneously, and therefore underframe must have enough intensity and certain rigidity.Existing track engineering bassinet structure, due to gauge requirement, in-vehicle device arrangement space is limited, cannot fully meet the space requirement of storage battery and other equipment.
Utility model content
In order to meet the installation space requirement of rail engineering automobile, improve the strength and stiffness of Undercarriage structure simultaneously, the utility model aims to provide a kind of rail engineering automobile Undercarriage structure, this Undercarriage structure is rational in infrastructure reliable, guaranteeing under the prerequisite that locomotive gauge requires, expand space between driver's cab space and machinery, guarantee the requirements of installation space of equipment, be conducive to guarantee traffic safety.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of rail engineering automobile Undercarriage structure, comprise mainly by draw beam, side bar, the undercarriage bea body skeleton that sleeper beam and in length and breadth beam are formed by fixedly connecting, its constructional feature is, in described undercarriage bea body skeleton, embedded bottom frame floor is housed, the level height of the upper surface of described bottom frame floor is lower than the level height of the upper surface of described side bar.
Be below the technical scheme of further improvement of the utility model:
The diff-H h of described bottom frame floor upper surface and described side bar upper surface is 20mm-200mm; Further, described h is 60mm-140mm.
Preferably, described rail engineering automobile Undercarriage structure is " work " font perpendicular to the cross sectional shape entirety of side bar length direction, thus, changed existing rail engineering automobile Undercarriage structure is the insufficient rigidity that " door " shape structure causes problem perpendicular to the cross sectional shape entirety of side bar length direction, " work " font structure can effectively improve the rigidity of Undercarriage structure.
According to actual needs, the upper surface that can make the upper surface of described bottom frame floor and the upper surface of described sleeper beam, draw beam all in same level, thereby expand to greatest extent the vertical space of rail engineering automobile.
By said structure, underframe is the main carrying structure of car body, and the structure of underframe mainly determines the aspect such as, facility location mode slow by shaft type, driver's cab quantity, mode of traction, hook.Therefore after the slow system of definite shaft type, driver's cab quantity, mode of traction and hook, consider the requirement of facility location, by bottom frame floor from becoming embedded at the caravel of Liang Tishang, on vertical, expand space between driver's cab and machinery, and Embedded bottom frame floor and beam body form failure-free plate-girder more, can improve the rigidity of Undercarriage structure.
Compared with prior art, the beneficial effects of the utility model are:
1. on vertical, expanded space between driver's cab and machinery, reduced carrying surface height, made full use of gauge space and carry out facility location;
2. the bulk strength and the rigidity that have improved underframe, strengthened reliability of structure, also improved device load-bearing capability simultaneously.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the front elevation of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the structural representation of undercarriage bea body skeleton described in the utility model; .
The specific embodiment
A kind of rail engineering automobile Undercarriage structure, as shown in Figure 4, its undercarriage bea body skeleton 1 is by draw beam 2, side bar 3, sleeper beam 4 and in length and breadth beam 5 are welded to form, and adopt and are arranged symmetrically with structure, make Undercarriage structure have good balance, this beam frame structure can be realized car body bearing function.
For meeting the demand of facility location, expand space between driver's cab and machinery, as illustrated in fig. 1 and 2, bottom frame floor 6 is embedded in undercarriage bea body skeleton 1, as shown in Figure 3, the level height of the upper surface of described bottom frame floor 6 is lower than the about 80mm of level height of the upper surface of described side bar; Adjust the structure of sleeper beam 4, draw beam 2 and the connection mode with side bar 3 simultaneously, make it to form lower concave space together with bottom frame floor 6, reduced carrying surface height, make full use of gauge space and carry out facility location.
Embedded bottom frame floor by with the welding of beam body skeleton, make to form and be similar to H-girder between the each parts of undercarriage bea body skeleton, can improve the strength and stiffness of Undercarriage structure, also improved device load-bearing capability simultaneously.
Certainly, according to factors such as shaft type, driver's cab quantity, mode of traction, hook delay, can select appropriate draw beam, sleeper beam, realize modular design; Embedded bottom frame floor also can be determined lower concave space according to actual conditions.
The content that above-described embodiment is illustrated should be understood to these embodiment only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
