Abstract
The utility model discloses a passenger train frame with novel outer crossbeam belongs to car parts design and processing technical field, and it is unreasonable to have solved traditional outer crossbeam structural design, causes the longeron easily to produce fatigue failure's problem. Main left longeron, the right longeron of including is equipped with an at least interior crossbeam between left longeron and right longeron, equally divide do not to fix outside left longeron, the right longeron to be equipped with at least one outer crossbeam, outer crossbeam and longeron adoption shaped as frame steel sheet support fixed connection. The utility model discloses improve simple structure, improve with low costsly, adopt rectangle steel sheet support as linking up parts, preceding, the back landing leg of shaped as frame steel sheet support all with longeron fixed connection, so both eliminated the moment of flexure of fore -and -aft direction, do not make the effort of outer crossbeam obtain disperseing, make the bending stiffness of longeron part improve to some extent simultaneously, the traditional outer crossbeam of thorough elimination causes longeron fatigue failure's hidden danger, the utility model discloses the practicality is strong, but wide application in car parts design and processing technical field.
Description
Technical field
The utility model belongs to automobile component design processing technique field, specifically, particularly relates to a kind of bus frame with novel outer crossbeam.
Background technology
First the version of vehicle frame should meet the requirement of automobile master layout, and vehicle frame is the matrix of whole automobile, and most parts of automobile and total Chengdu are supported by vehicle frame and locates, so vehicle frame should have enough strength and stiffness.Longitudinal beam type vehicle frame is by two longerons and some crossbeams, and the rigid frame connected into riveted joint or welding manner, vehicle frame framework is generally stamped to form with low-alloy automotive frame steel plate special.Because of body structure restriction, the outer crossbeam that outer crossbeam is fixedly connected with longeron need to palintrope 100mm, as shown in Figure of description Fig. 1, in use procedure there is cracking in this place's longeron top airfoil and side, this place's longeron is greatly stressed and more concentrated, particularly during vehicle jumping pit, outer cross rail outer application force is downward, stainless steel strut application force upwards, two force directions on the contrary and all concentrate again and act on chassis side rail, outer crossbeam backward bending also by generation Moment in this place of longeron, longeron may be made after alternating action to produce endurance failure.
Summary of the invention
The utility model discloses a kind of bus frame with novel outer crossbeam, unreasonable for solving the design of tradition outer beam structure, cause longeron easily to produce the problem of endurance failure.
The utility model is achieved through the following technical solutions:
A kind of bus frame with novel outer crossbeam, comprise longeron, crossbeam, described longeron comprises left longeron, right vertical beam, described crossbeam comprises interior crossbeam, outer crossbeam, at least one interior crossbeam is provided with between described left longeron and right vertical beam, at least one outer crossbeam is fixed with respectively outside described left longeron, right vertical beam, described outer crossbeam and longeron adopt shaped as frame stainless steel strut to be fixedly connected with, front leg strut, the rear support leg of described shaped as frame stainless steel strut are all fixedly connected with longeron, and described outer beam-ends is fixedly connected with shaped as frame stainless steel strut main body.
The direction of the end deflection shaped as frame stainless steel strut rear support leg of described outer crossbeam is fixedly connected with shaped as frame stainless steel strut main body.
The front leg strut of described shaped as frame stainless steel strut, rear support leg adopt riveted joint or electric welding mode to be fixedly connected with.
Described outer crossbeam adopts the mode of rivet or electric welding to be fixedly connected with shaped as frame stainless steel strut main body.
Compared with prior art, the beneficial effects of the utility model are:
The utility model modified node method is simple, improving cost is low, adopt rectangular steel plates support as interface components, the forward and backward supporting leg of shaped as frame stainless steel strut is all fixedly connected with longeron, so both eliminates the moment of flexure of fore-and-aft direction, does not make the application force of outer crossbeam be disperseed, make the bending stiffness of longeron local increase simultaneously, the outer crossbeam of thorough elimination tradition causes the hidden danger of longeron endurance failure, and the utility model is practical, can be widely used in automobile component design processing technique field.
Accompanying drawing explanation
Fig. 1 is traditional bus frame local structure schematic diagram;
Fig. 2 is the utility model structural representation.
In figure: 1. left longeron; 2. right vertical beam; 3. crossbeam in; 4. outer crossbeam; 5. shaped as frame stainless steel strut; 6. front leg strut; 7. rear support leg.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of bus frame with novel outer crossbeam, comprise longeron, crossbeam, described longeron comprises left longeron 1, right vertical beam 2, described crossbeam comprises interior crossbeam 3, outer crossbeam 4, at least one interior crossbeam 3 is provided with between described left longeron 1 and right vertical beam 2, at least one outer crossbeam 4 is fixed with respectively outside described left longeron 1, right vertical beam 2, described outer crossbeam 4 and longeron adopt shaped as frame stainless steel strut 5 to be fixedly connected with, front leg strut 6, the rear support leg 7 of described shaped as frame stainless steel strut 5 are all fixedly connected with longeron, and described outer crossbeam 4 end is fixedly connected with shaped as frame stainless steel strut 5 main body.
The direction of end deflection shaped as frame stainless steel strut 5 rear support leg of described outer crossbeam 4 is fixedly connected with shaped as frame stainless steel strut 5 main body.
The front leg strut 6 of described shaped as frame stainless steel strut 5, rear support leg 7 adopt riveted joint or electric welding mode to be fixedly connected with.
Described outer crossbeam 4 adopts the mode of rivet or electric welding to be fixedly connected with shaped as frame stainless steel strut 5 main body.
The utility model adopts rectangular frame support 5 as interface components, front leg strut 6, the rear support leg 7 of framework stainless steel strut 5 are all fixedly connected with longeron, so both eliminate the moment of flexure of fore-and-aft direction, the application force of outer crossbeam 4 is made again to be disperseed, make the bending stiffness of longeron local increase simultaneously, the outer crossbeam 4 of thorough elimination tradition causes the hidden danger of longeron endurance failure, and the utility model can be widely used in automobile component design processing technique field.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
