Abstract
The utility model discloses an anti-collision beam for the back of a truck. The anti-collision beam comprises a steel beam; two first spring components are arranged at the top of the beam symmetrically;two second spring components are arranged at the front of the beam symmetrically; an anti-collision strip is matched between the two second spring components; the face, back to the second spring components, of the anti-collision strip is provided with a convex circular arc surface; a gap is reserved between the beam and the anti-collision strip; multiple cushion pads are glued on the front of the beam; when the truck is subjected to smaller collision, the second spring components are contracted, the collision force is absorbed by the anti-collision strip, the steel beam is prevented from deformation, when the collision force is larger, the first spring components are elastically bent, the steel beam is moved backwards, when the collision force disappears, the steel beam is returned to the original position by means of the elastic deformation of the second spring components, the device has better buffer performances, the risk degree of accidents can be lowered, the deformation is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to the collision prevention girders that a kind of truck back is used.
Background technology
existing high capacity waggon is in reversing or driving process, its afterbody often can run into scraping, existing way is in a collision prevention girders of the rear end of lorry welding, collision prevention girders is common girder steel, by playing certain protective effect to the afterbody of automobile after welded steel beam, but single girder steel, its hardness is larger, the function without buffering, after being clashed into, can produce larger distortion, cause the later stage normally to use, simultaneously owing to not thering is flexibility, when receiving rear-end collision, to front vehicle, caused larger potential safety hazard, so be not suitable for promoting the use of.
Summary of the invention
The technical problems to be solved in the utility model is to provide the collision prevention girders that a kind of truck back is used, and this device has good shock absorber, can reduce accident hazard degree, effectively reduces distortion simultaneously, increases service life.
For addressing the above problem, the utility model adopts following technical scheme:
The collision prevention girders that a kind of truck back is used, the crossbeam that comprises a steel, at the top of this crossbeam, be symmetrically arranged with two the first spring assemblies, the front of described crossbeam is symmetrically arranged with two the second spring assemblies, and between two second spring assemblies, be combined with an anticollision strip, this anticollision strip dorsad side of the second spring assembly is the arc surface of an evagination, between described crossbeam and anticollision strip, leaves space, at positive cementing several cushion rubbers that has of described crossbeam.
As preferred technical scheme, described the first spring assembly comprises two upper and lower symmetrically arranged the first fasteners, and be buckled in the first spring between two first fasteners, and the first fastener of described bottom is connected with beam welding, and the first fastener and the car body at top are welded to connect.
As preferred technical scheme, described the second spring assembly comprises the second fastener of two forward and backward settings, and be connected to the second spring between two second fasteners, and the second fastener of described rear end is connected with beam welding, and the second fastener of front end is connected with anticollision strip.
As preferred technical scheme, described cushion rubber is spherical, and described the second spring assembly is compressed to the thickness that length after the limit is less than cushion rubber.
As preferred technical scheme, on the arc surface of described anticollision strip, be bonded with warning patch.
The beneficial effects of the utility model are: when lorry is subject to less shock, the second spring assembly shrinks, by anticollision strip absorbing forces of impact, prevent girder steel distortion, when suffered impact is larger, the first spring assembly generation elastic bending, girder steel is displacement rearward, when impact disappears, rely on the elastic deformation of the second spring assembly, make girder steel reposition, this device has good shock absorber, can reduce accident hazard degree, effectively reduce distortion simultaneously, increase service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is birds-eye view of the present utility model;
Fig. 2 is front view of the present utility model.
The specific embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult the collision prevention girders that a kind of truck back shown in Fig. 1 and Fig. 2 is used, the crossbeam 1 that comprises a steel, at the top of this crossbeam 1, be symmetrically arranged with two the first spring assemblies 2, the front of described crossbeam 1 is symmetrically arranged with two the second spring assemblies 3, and between two second spring assemblies 2, be combined with an anticollision strip 4, this anticollision strip 4 dorsad side of the second spring assembly 3 is the arc surface of an evagination, between described crossbeam 1 and anticollision strip 4, leave space, at positive cementing several cushion rubbers 5 that has of described crossbeam 1.
Wherein, described the first spring assembly 2 comprises two upper and lower symmetrically arranged the first fasteners, and is buckled in the first spring between two first fasteners, and the first fastener of described bottom is connected with beam welding, and the first fastener and the car body at top are welded to connect.
Described the second spring assembly 3 comprises the second fastener of two forward and backward settings, and is connected to the second spring between two second fasteners, and the second fastener of described rear end is connected with beam welding, and the second fastener of front end is connected with anticollision strip.
Described cushion rubber 5 is spherical, and described the second spring assembly 2 is compressed to the thickness that length after the limit is less than cushion rubber 3.
On the arc surface of described anticollision strip 4, be bonded with warning patch 401.
The beneficial effects of the utility model are: when lorry is subject to less shock, the second spring assembly shrinks, by anticollision strip absorbing forces of impact, prevent girder steel distortion, when suffered impact is larger, the first spring assembly generation elastic bending, girder steel is displacement rearward, when impact disappears, rely on the elastic deformation of the second spring assembly, make girder steel reposition, this device has good shock absorber, can reduce accident hazard degree, effectively reduce distortion simultaneously, increase service life.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
