Abstract
The utility model relates to a locomotive underframe boundary beam on electric locomotives, diesel locomotives and engineering maintaining automobiles, which is characterized in that the boundary beam is a solid body, so that the boundary beam with variable sections is easy to achieve in the process. The boundary beam protrudes upwards in the middle of an upper plane and protrudes downwards between two bogies. The locomotive underframe boundary frame mainly aims at consuming the weight of a large-axle heavy locomotive body and enabling the center of gravity of the locomotive body to be lower, so that a locomotive can have better dynamic performance. For the large-axle heavy locomotive, according to the locomotive underframe boundary beam, lengthening a locomotive body to bear the weight is avoided and the locomotive underframe boundary beam is capable of enabling the weight of an underframe to be increased by 80% to 120% on the basis of a common boundary beam.
Description
Technical field
The utility model relates to the underframe side bar on a kind of electric locomotive, diesel locomotive, the engineering maintenance car.
Background technology
The underframe side bar cross sectional shape of existing locomotive and engineering maintenance car all is the distortion of " mouth " font or " mouth " font, reaches " day " shape etc. like
; This side bar is owing to be to adopt to press ellbeam and riser welding or " worker " word beam and riser welding or press ellbeam to form with pressing ellbeam welding or four plate weldings; Thereby the cross sectional shape of this beam is not easy to form variable section, the weight that this beam can not actv. digestion macro-axis heavy-duty machine car car body simultaneously.Thereby in macro-axis heavy-duty machine car, generally between machinery, adding the iron of delaying unloading, the installation of the iron of delaying unloading occupies space bigger between machinery, makes the facility location difficulty; The iron of maybe will delaying unloading is suspended on the underframe bottom, has potential safety hazard.
The utility model content
The purpose of the utility model is, to the deficiency of prior art, provides a kind of locomotive underframe solid side bar, and the underframe side bar can be realized variable section, makes the weight major part of car body be distributed in the underframe part, guarantees that locomotive has good dynamic performance.
The technical scheme of the utility model does, a kind of locomotive underframe side bar is characterized in that, said side bar is a solid.
Directly adopt a plate iron cutting processing, be welded, this side bar not only cross sectional shape can change continuously arbitrarily, and can solve the difficult problem that macro-axis heavy-duty machine car need not add the iron of delaying unloading.
The side bar two ends may extend to the front end-plate of draw beam.
The bottom surface of said side bar between two bogie trucks can be protruded downwards, plays skirtboard moulding effect.
The part of side bar between machinery, promptly in-plane raises up on the underframe, and the part of skeleton and side structure is installed as equipment.
Know by above; The utility model is as a kind of locomotive underframe side bar; The variable section side bar is realized on technology easily, side bar in last in-plane protruding upward and between two bogie trucks side bar protrude downwards, its main purpose is a consumption macro-axis loaded vehicle body weight; And make the center of gravity of car body low as far as possible, so that locomotive has good dynamic performance; Underframe side bar part protruding upward also can be used as a part and the Machine Room equipment installation skeleton of side structure simultaneously, and projection can play skirtboard moulding effect downwards.Concerning macro-axis heavy-duty machine car, the utility model can be in order to digest weight, and increase the length (increasing the space of Machine Room, so that the iron of delaying unloading is installed) of car body; Can make underframe weight on common side bar basis, increase by 80%～120%.

The specific embodiment
Embodiment 1
Like Fig. 1, shown in Figure 2, a kind of locomotive underframe side bar, side bar 1 is a solid.
Embodiment 2
A kind of locomotive underframe side bar, side bar 1 is a solid, and side bar 1 two ends extend to the front end-plate of draw beam, and promptly side bar has solid draw beam side bar 2.
A kind of locomotive underframe side bar; Side bar 1 is a solid, and there is solid draw beam side bar 2 at side bar 1 two ends, and in-plane has convexity 3 upwards on the side bar 1; Protruding 3 the outside is processed with step; The covering overlap joint of side structure is on the step of side bar, and side structure covering postwelding and side bar lateral surface become a complete plane, and the equipment mount pad can directly be welded on the middle part protruding 3 simultaneously.
Embodiment 4
A kind of locomotive underframe side bar, side bar 1 is a solid, there is solid draw beam side bar 2 at side bar 1 two ends, protrude downwards in the middle of side bar 1 bottom surface, play skirtboard moulding effect.In-plane has convexity 3 upwards on the side bar 1; Protruding 3 the outside is processed with step; The covering overlap joint of side structure is on the step of side bar, and side structure covering postwelding and side bar lateral surface become a complete plane, and the equipment mount pad can directly be welded on the middle part protruding 3 simultaneously.
Claims (4)
1. a locomotive underframe side bar (1) is characterized in that, said side bar (1) is a solid.
2. according to the said a kind of locomotive underframe side bar of claim 1, it is characterized in that said side bar (1) two ends contain draw beam side bar (2).
3. according to the said a kind of locomotive underframe side bar of claim 1, it is characterized in that, protrude downwards in the middle of said side bar (1) bottom surface.
