Abstract
The utility model discloses an anticollision supporting beam behind passenger train, including two parallel arrangement's back bracing piece, two bending pole that set up with the symmetry, the stiffener that is used for connecting back bracing piece and bending pole, back bracing piece includes the bracing piece straight -bar section of lower part and the bracing piece segmental arc on upper portion, upper end its probe distance of every 50mm on perpendicular distance of bracing piece segmental arc 127mm that differs, the vertical height of continuity is 100mm, middle part its probe distance of every 50mm on perpendicular distance of bracing piece segmental arc 25mm that differs, the vertical height of continuity is 150mm. The utility model has the advantages of prior art's drawback, the reasonable novelty of structural design can be overcome to it.
Description
Technical field
This utility model relates to a kind of passenger vehicle rear anti-crash and supports beam, belongs to automobile manufacturing field。
Background technology
Taking more than 9 people (including operating seat), generally have square compartment, for the commercial car of carrying passenger and personal luggage thereof, this kind of vehicle is mainly used in public transport and group's transport uses。Passenger vehicle has monolayer, also has bilayer；Have hinged, also have drawbar trailer type。There are two, single-door, or have luggage compartment。Most passenger vehicles adopt Diesel Driven, currently also have pure electric vehicle, all-metal body。Calculate the consumed energy and shared path area according to number of passengers, mass transportation facilities is than individual vehicle economy, and this is the one of the main reasons that many countries first develop public transport passenger vehicle。Saying from world wide, car manufacturing and universal ratio are wide, therefore as the Coach Manufacture of public transport main body, no matter are from design concept or designing technique, all show quite ripe, and Bus Technology level and the capacity of scientific research in Europe occupy first place in the world。The designed capacity of Chinese Bus Industry and manufacture level, occupy important position in the world。The rear anti-crash of passenger vehicle supports beam and is positioned at the rear end of passenger vehicle, and when there is rear-end collision, it is stress bear maximum pressure at first, and it is not high that existing rear anti-crash supports beam strength, and when passenger vehicle collides, its framework is yielding causes danger。
Utility model content
For the deficiency that prior art exists, technical problem to be solved in the utility model is to provide a kind of passenger vehicle rear anti-crash and supports beam, and support safety is reliable, and intensity is high。
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of passenger vehicle rear anti-crash supports beam, including two back support rods be arrangeding in parallel, two with symmetrically arranged bending bar, for connecting back support rod and the bracing piece of bending bar；Described back support rod includes the support bar straight bar section of bottom and the support bar segmental arc on top；The upper end of described support bar segmental arc differs 127mm every its horizontal range of 50mm in vertical dimension, and the vertical height of continuity is 100mm；The middle part of described support bar segmental arc differs 25mm every its horizontal range of 50mm in vertical dimension, and the vertical height of continuity is 150mm；The bottom of described support bar segmental arc differs 13mm every its horizontal range of 50mm in vertical dimension, and the vertical height of continuity is 150mm；Being provided with an obtuse angle bending in the middle part of described bending bar, bending angle is 137 degree；Described every back support rod is connected by two bracing pieces be arrangeding in parallel with bending bar；The middle part of described bracing piece is arc, and its radian is 1.25。
Optimizing, above-mentioned passenger vehicle rear anti-crash supports beam, and described bracing piece, back support rod, bending bar are hollow square tube, and the wall thickness of bracing piece is more than back support rod and bending bar 2mm。
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel。Rear anti-crash is supported beam it is divided into bracing piece, back support rod, bending bar, ease of assembly, it is to avoid the assembling inconvenience that in prior art, whole framework weight is brought more greatly。Bracing piece, back support rod, bending bridge are simulated by the 3D mode modeled, define crisscross supporting network, add the skeleton strengths in tension and compression in all angles, in collision experiment, be designed to the mode that arc combines with linear type, and its radian is through calculating best arc configuration, enhance the bulk strength of a support component, in an impact, reduce deformation, improve intensity, add the safety of passenger vehicle。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1 be back support rod, 2 be bending bar, 3 be bracing piece, 4 be support bar straight bar section, 5 for support bar segmental arc。
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with accompanying drawing and specific embodiment。
This utility model is that a kind of passenger vehicle rear anti-crash supports beam, including two back support rods be arrangeding in parallel, two with symmetrically arranged bending bar, for connecting back support rod and the bracing piece of bending bar；Described back support rod includes the support bar straight bar section of bottom and the support bar segmental arc on top；The upper end of described support bar segmental arc differs 127mm every its horizontal range of 50mm in vertical dimension, and the vertical height of continuity is 100mm；The middle part of described support bar segmental arc differs 25mm every its horizontal range of 50mm in vertical dimension, and the vertical height of continuity is 150mm；The bottom of described support bar segmental arc differs 13mm every its horizontal range of 50mm in vertical dimension, and the vertical height of continuity is 150mm；Being provided with an obtuse angle bending in the middle part of described bending bar, bending angle is 137 degree；Described every back support rod is connected by two bracing pieces be arrangeding in parallel with bending bar；The middle part of described bracing piece is arc, and its radian is 1.25。Described bracing piece, back support rod, bending bar are hollow square tube, and the wall thickness of bracing piece is more than back support rod and bending bar 2mm。
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel。Rear anti-crash is supported beam it is divided into bracing piece, back support rod, bending bar, ease of assembly, it is to avoid the assembling inconvenience that in prior art, whole framework weight is brought more greatly。Bracing piece, back support rod, bending bridge are simulated by the 3D mode modeled, define crisscross supporting network, add the skeleton strengths in tension and compression in all angles, in collision experiment, be designed to the mode that arc combines with linear type, and its radian is through calculating best arc configuration, enhance the bulk strength of a support component, in an impact, reduce deformation, improve intensity, add the safety of passenger vehicle。
Certainly, described above is not that this utility model is also not limited to the example above to restriction of the present utility model; those skilled in the art; in essential scope of the present utility model, change, remodeling, interpolation or the replacement made, all should belong to protection domain of the present utility model。
