The device comprises a connecting plate, a concave protective plate, a rubber block, a longitudinal push rod, a diagonal draw rod and a vertical hanger rod, and is characterized in that the upper end of the connecting plate is connected with a frame, the lower end of the connecting plate is connected with the concave protective plate, two ends of the longitudinal push rod are respectively hinged with the frame and the concave protective plate, two ends of the diagonal draw rod are respectively hinged with the connecting plate and the longitudinal push rod, the vertical push rod is respectively hinged with the frame and the concave protective plate, the rubber block is embedded into the concave protective plate and is fixed by bolts, and the vertical hanger rod is respectively hinged with the frame and the concave protective plate. The multi-rod type underrun protection device disclosed by the utility model has the advantages that 1) underrun can be effectively prevented, and the passive safety of the truck can be improved; 2) the absorptivity of impact energy is high; and 3) the connection is reliable, and the device is convenient to disassemble and facilitates engineering application.

Description

The medium and heavy truck tailstock protection of a kind of multi-rod underrun protection
Affiliated technical field
The utility model relates to a kind of tailstock protection underrun protection, and particularly a kind of medium and heavy truck tailstock protection underrun protection belongs to the automotive safety technical field.
Background technology
At present, great majority are in that particularly the chassis of tip car is higher with medium and heavy truck, and the ground Clearance is big, so has produced bigger space at the rear lower of the tailstock.And the vehicle tailstock of this type is not generally installed tailstock protection underrun protection; What have has only installed simple bumper frame; But the bumper frame intensity of the type is limited and few to impact energy absorption, can not play the actv. protective action, particularly lacks the ability of effective underrun.
Along with the development of society, private car obtains effectively universal.Yet medium and heavy truck generally lacks actv. tailstock protection underrun protection, and the afterbody that very easily gets into medium and heavy truck when causing sedan and medium and heavy truck to knock into the back takes place to bore and hits, and causes great personal casualty and property damage.
Utility model patent ZL201020173471.X is through being provided with adapter plate and the guar plate identical with the small passenger car bumper height; And between adapter plate and guar plate, add shock mount and absorb Impact energy at guar plate surface coverage rubber plate, vehicle plays a protective role to knocking into the back.Above-mentioned patent adopts adapter plate that the whole protection device is connected to ground, and requires adapter plate that enough strength and stiffness will be arranged, and connects to want reliable, otherwise under high-speed impact, causes coming off of protective device easily, takes place to bore and hits.In addition, owing to the small passenger car bumper height differs, so above-mentioned patent is difficult to cover whole car type.The utility model provides the medium and heavy truck tailstock protection of a kind of multi-rod underrun protection; Change the arm of force length of bump moment through the combination of connecting rod; The bump that prevents connecting panel fractures, and prevents coming off of whole protection device through connecting rod, can effectively prevent to bore the generation of hitting; Improve the passive satety of vehicle, reduced the vehicle crew's injures and deaths that knock into the back.
Summary of the invention
In the problem that exists with lorry tailstock protective device, the utility model provides the medium and heavy truck tailstock protection of a kind of multi-rod underrun protection at present, and when knocking into the back generation, effectively the absorbing impact energy can effectively prevent to bore the generation of hitting.
The utility model realizes that through following technical scheme it comprises connecting panel, spill guar plate, rubber block, vertical push rod, digonal link, vertical suspension rod.It is characterized in that: the connecting panel upper end links to each other with vehicle frame; The lower end links to each other with the spill guar plate; Vertical push rod two ends are pivotally connected frame and spill guar plate respectively, digonal link two ends be articulated and connected respectively plate and vertical push rod, and vertical pusher is distinguished pivotally connected frame and spill guar plate; Rubber block embeds in the spill guar plate, and uses bolt.
The principle of work of the utility model is: bump makes full use of rubber block when taking place shock damping action absorbs Impact energy.Vertical push rod can provide antagonistic force with digonal link, stops the spill guar plate to move inward, and a vertical push rod and spill guar plate position that is articulated and connected is positioned at below the device, has reduced to clash into the arm of force length of moment.Since hinged between above-mentioned connecting rod and the parts, allow to exist little displacement to carry out buffering energy-absorbing, and can stop big displacement, anti-locking apparatus distortion is excessive, causes and bores the generation of hitting.Vertical pusher is pivotally connected frame and spill guar plate respectively, can prevent that the brill that causes hits because protective device integral body comes off.
The beneficial effect of the utility model is: 1) effectively prevent to bore the generation of hitting, can improve the passive satety of vehicle; 2) knockout process is high to the absorptivity of Impact energy; 3) connect reliably, convenient disassembly is applicable to practical applications.
Description of drawings
The system schematic of Fig. 1-the utility model (front view).
The system schematic of Fig. 2-the utility model (left view).
The specific embodiment
As shown in Figure 1, the utility model comprises rubber block 1, spill guar plate 2, connecting panel 3, vehicle frame 4, vertical suspension rod 5, vertical push rod 6, digonal link 7 and bolt of rear end plate 8.It is characterized in that: vehicle frame 4 is connected with connecting panel 3 upper ends, and the lower end of connecting panel 3 is connected with spill guar plate 2, and rubber block 1 is embedded in the spill guar plate 2 and through bolt 8 and fixes; One end and the vehicle frame 4 of vertical push rod 6 are articulated and connected, and the other end and spill guar plate 2 are articulated and connected, and are articulated and connected through digonal link 7 between vertical push rod 6 and the connecting panel 3.In addition, spill guar plate 2 is articulated and connected on vehicle frame 4 through vertical suspension rod 5 with its pivotally attached.
The principle of work of the utility model is: when bump takes place, at first contacted with the vehicle that knocks into the back by bolt of rear end plate 8 rubber blocks 1 fixing and that be embedded on the spill guar plate 2, the shock damping action that makes full use of rubber block 1 absorbs Impact energy.Vertical push rod 6 is articulated and connected with vehicle frame 4, spill guar plate 2 respectively; Also be connected between vertical simultaneously push rod 6 and the connecting panel 3 through digonal link 7; Form stable triangle; Strengthen the limitation capability of spill guar plate 2 at vehicle heading, vertical simultaneously push rod 6, digonal link 7 provide antagonistic force to stop spill guar plate 2 to move inward; Vertical push rod 6 is positioned at the device below with a position that is articulated and connected of spill guar plate 2, has reduced the arm of force length of bump moment, prevents that connecting panel 3 bumps from fractureing; Respectively being articulated and connected is in the micro-displacement that allows relative initial position when receiving longitudinal impact power, plays buffer action and continues to absorb Impact energy, and the vehicle of avoiding knocking into the back produces excessive deceleration/decel the member is damaged; Spill guar plate 2, the vehicle frame 4 vertical suspension rod 5 that is articulated and connected respectively; Vertical 5 pairs of spill guar plates 2 of suspension rod do not play fixing and thrust function; When impact cross havoc vertical push rod 6 during with digonal link 7 vertical suspension rod 5 can prevent that the whole protection device from coming off, and avoids boring the generation of hitting.
