Description
Technical field
The utility model relates to commercial vehicle/comm..vehicle passive security field, refers to a kind of commercial vehicle/comm..vehicle front underrun protection device particularly.
Background technology
At present, vehicle all adopts bumper/spoiler to protect as front portion, but due to commercial vehicle/comm..vehicle bumper/spoiler higher, good protective action can not be played.And bumper/spoiler is arranged on outside car body, although structure is comparatively simple, be difficult to ensure the Joint strenght with vehicle rail, the effect playing front lower portion protection that can not be fully effective, as when with car generation head-on crash, car may pierce bottom commercial vehicle/comm..vehicle and cause serious accident.In order to reduce the loss that vehicle frontal collision accident is brought, China has formulated " commercial vehicle/comm..vehicle front lower portion requirement of shelter " (GB26511-2011) new standard, requires that commercial vehicle/comm..vehicle must install front underrun protection device.
Summary of the invention
The purpose of this utility model will overcome upper the deficiencies in the prior art exactly, provides that a kind of structure is simple, intensity is high and the commercial vehicle/comm..vehicle front underrun protection device that cost is low.
To achieve these goals, commercial vehicle/comm..vehicle front underrun protection device designed by the utility model, it is characterized in that: comprise protection crossbeam and two supports for being connected with vehicle rail, described protection crossbeam is provided with several coupling nuts, described support entirety is by level right angle limit, the triangular structure that the straight vertical arm of angle and hypotenuse are formed, described level right angle limit is provided with several captive nuts for being connected with vehicle rail, the described straight vertical arm of angle is provided with connecting angle, described connecting angle is provided with several bolts, the coupling nut that several bolts described are corresponding with on protection crossbeam respectively connects.
Further step ground, described protection crossbeam is provided with connecting panel, and described coupling nut is fixed on connecting panel.
Further, the cross-sectional plane of described protection crossbeam is rectangle.
Again further, described support vertical section is a few font, saving steel.
Again further, the described straight vertical arm of angle arranges support breach, described connecting angle is arranged along support breach and is extended to the bottom of support, is connected with a few font limit of support wing.Add the area of junction, aspect operates, and connects more firm, and connecting wing extends to the bottom surface that frame bottom act as support, too increases the fastness of this structure.
The utility model has the advantage of: protection crossbeam is connected to commercial vehicle front lower portion by support, support entirety adopts triangular structure, stability is very good, and support is blanked part, decrease cost, support arranges captive nut and connecting wing, make full use of the frame carling structure of existing vehicle, increase a small amount of parts, composition commercial vehicle/comm..vehicle front lower portion protective system.The front underrun protection device that this structure is simple, easy for installation, commonality is good, productive costs is not high, has the collision prevention function of high strength, can meet the requirement of national standard regulation.
