To achieve these goals, the technical scheme that the utility model adopts is:
Undercarriage structure installed by a kind of power bag, comprises at least two the first side bars and the second side bar longitudinally arranged, the first crossbeam of lateral arrangement and second cross beam; Described first side bar is all positioned at the outside of the second side bar, and the end of the first side bar and the second side bar is all fixed together by corresponding first crossbeam and second cross beam and forms closed framed structure; Its constructional feature is, be fixedly connected with the slope section bar longitudinally arranged inside described second side bar, the two ends of two slope section bars are all fixed on corresponding first crossbeam and second cross beam; Two slope section bars are fixedly linked by the access hole crossbeam of lateral arrangement, and on access hole crossbeam, be fixed with the access hole longeron longitudinally arranged; Access hole framed structure is formed between described access hole crossbeam and access hole longeron.
Thus, by above structure design, Undercarriage structure installed by power bag can meet PII type requirement of strength in EN12663-2010 standard.
According to embodiment of the present utility model, can also do further to optimize to the utility model, the technical scheme below for being formed after optimization:
Preferably, described access hole crossbeam and each three of access hole longeron, form four access holes between spaced three access hole crossbeams and three access hole longerons, namely define four space for maintenances.
The medial surface opposed vertical face tilt of described slope section bar is arranged; The end face opposed vertical face tilt of described access hole crossbeam is arranged, the side end face opposed vertical face tilt of described access hole longeron is arranged.Preferably, described angle of inclination is 3 °-8 °.More preferably, described angle of inclination is 5 °
The bottom face of described first side bar, the second side bar, first crossbeam and second cross beam is on same horizontal surface.
The bottom face of described access hole crossbeam and access hole longeron is on same horizontal surface.
Preferably, described first side bar and the second side bar are respectively two.
Compared with prior art, the beneficial effects of the utility model are: the utility model is particularly useful in aluminum alloy Motor train unit body structure, effectively can solve the safety that power bag is installed, meet the requirement of strength of relevant criterion, extend the service life of car body and equipment, and simple and light, easy for installation, can in the widespread use of railway transportation equipment field.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
