Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
Shown in Fig. 1-2, the utility model provides a kind of testboard bay assembly of engine, comprise the first supporting leg 10 and the second supporting leg 20 being supported in engine, also comprise bracing frame 30, bracing frame 30 is connected to the first end face 41 of engine cylinder-body 40, first end face 41 is positioned at the end face that engine cylinder-body 40 is connected with wheel box, and the 3rd supporting leg 50 is supported in bracing frame 30.Adopt technique scheme, bracing frame 30 is connected on engine cylinder-body, and the position that link position and wheel box are connected to engine cylinder-body is identical, and the 3rd supporting leg 50 is supported on bracing frame 30, be close to the Support Position of engine when more than making testboard bay assemble the Support Position of engine cylinder-body and car load, comparatively prior art is compared, and reduces the difference of Support Position, improve the accuracy of measurement result, support strength is reliable simultaneously.
In above-mentioned technical scheme, bracing frame 30 comprises web joint 31, and from the back up pad 32 that web joint 31 extends to the side away from engine cylinder-body 40, web joint 31 is connected with the first end face 41, and the 3rd supporting leg 50 is supported in back up pad 32, in this scheme, the structure of bracing frame 30 is simple, easy to process.
And preferably, web joint 31 extends along the circumference of the first end face 42 and forms loop configuration, web joint 31 arranges multiple connecting hole 311 on its ring surface, be fastened by bolts in engine cylinder-body 40, this structure by the whole ring surface of web joint 31 with the connection of engine cylinder-body 40, improve both strength of joint, avoid causing Joint failure under the effect of anchorage force, and the web joint 31 of loop configuration can weight reduction, and save material.
Further, back up pad 32 extends to form tubular structure from the inwall of web joint 31 to the side away from engine cylinder-body 40, the contour structures of this structure and gear box casing matches, and height and the car load of the strong point assemble substantially identical, and the difference of its support arrangement can reduce further.
The back up pad 32 of tubular structure, its wall thickness is thinner, in order to improve the strength and stiffness of back up pad 32 self, also the preferred position be connected with the 3rd supporting leg 50 in back up pad 32 arranges reinforcement structure, strengthen the stability of strutting system that structure can improve back up pad 32, reduce bracing frame 30 and deform in support process or the equivalent risk that festers.
The plan of establishment strengthening structure has multiple, and as embodiment one, strengthen structure and comprise the enhancement Layer fitting in back up pad 32 outer wall, enhancement Layer is high strength layer; And for example embodiment two, strengthens structure and comprises the stiffening plate 60 being fixed in back up pad 32 outer wall.Particularly, the inwall of stiffening plate 60 is arc surface, outer wall is that multiple face connects and forms, outer wall and inwall connect and form closed polyhedral structure, the stiffening plate 60 of polyhedral structure is fitted by the outer wall of inwall and back up pad 32, realize the increase of back up pad 32 at the thickness with the 3rd supporting leg 50 junction with this, and serve booster action.Two embodiments are compared, embodiment one adopts the enhancement Layer of high strength to improve its intensity, embodiment two improves its intensity by the thickness increasing back up pad 32, two kinds of embodiments all can reach the object improving strength and stiffness, but consider that back up pad 32 and stiffening plate 60 can be integral structure, realize as adopted the techniques such as one casting or machine work, its processing technology is simple, therefore, in the present embodiment, preferred embodiment two.
Simultaneously, in order to ensure the strength of joint of the 3rd supporting leg 50 and back up pad 32, also preferred setting in back up pad 32 connects plane 321,3rd supporting leg 50 connects thereon, this approach increases contact area when both connect, add strength of joint, compared with the structure be connected with arcwall face, reliability, stability are all higher.
The testboard bay assembly that the utility model provides, also preferably arranges loss of weight breach 322 in back up pad 32, and this scheme, on the basis not affecting back up pad 32 support strength, can reduce material further, reduces the weight of testboard bay assembly.
Below be only preferred implementation of the present utility model, it is to be noted, these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model, and, after having read content of the present utility model, relevant technical staff in the field can make various change or amendment to the utility model, and these equivalent form of values fall into the application's appended claims limited range equally.
