Abstract
The invention relates to a novel truck back anti-collision rod which is composed of a supporting frame, an anti-collision plate, a rubber plate, a spring, unthreaded screw rods, anti-collision rods and a steel wire net. The anti-collision rod is connected to the supporting frame. A bolt fixing hole is formed in the supporting frame. Through holes which are the same in size are respectively formed in the four corners of the anti-collision rod body A and the four corners of the anti-collision rod body B. The unthreaded screw rods penetrate through the through holes and can slide in the through holes. Nuts are fixed at tail ends of the unthreaded screw rods. The elastic rubber plate is arranged on the anti-collision plate. A steel wire net is arranged between the supporting frame and the anti-collision rod B. The novel truck back anti-collision rod is of a multi-layer anti-collision structure, is remarkable in buffer effect, and can greatly reduce rear-end damage and prevent a car from entering the bottom of a truck.
Description
Technical field
The present invention relates to a kind of novel truck Grard Assy, particularly a kind ofly prevent that roadlice from piercing the anti-drilling shape device of truck, belongs to crash bar technical field.
Background technology
High capacity waggon is a kind of full size vehicle, and truck tail is generally all equipped with crash bar, but on crash bar, there is no shock absorber, if car rear-end knocks the afterbody of high capacity waggon, car can be injured very serious.Particularly, when express highway is run at high speed, if car rear-end knocks the afterbody of high capacity waggon, roadlice headstock often can directly creep into bottom, truck compartment, causes the head of navigating mate and passenger seriously injured, even dead.And high capacity waggon is also because the collision of the pony truck that pierced causes a lot of beyond thought injuries, flanged (FLGD) oil tank or gas tank are for example housed above high capacity waggon, roadlice pierces lorry bottom, may cause the injures and deaths of circumference in several.Therefore, on market, need to have a kind of heavy-duty truck rear bumper with shock absorber to be arranged on lorry rear lower position, when knocking high capacity waggon to play buffer action, car rear-end can also prevent that roadlice from piercing truck bottom, not only reduces the injury that can also reduce personnel on high capacity waggon while knocking into the back to the injures and deaths of the dillies such as rear portion car.
United States Government's lower edge terrain clearance of mandatory provision lorry protecting device for rear lower part in 26 days January in 1998 must not surpass 560mm, the lower edge terrain clearance of Europe ECE master gauge order car protecting device for rear lower part can not surpass 550mm, the lower edge of Japan regulation lorry its protecting device for rear lower part under light condition overhead height can not surpass 550mm, and the Chinese GB11567.2-2001 clearly lower edge terrain clearance of regulation lorry protecting device for rear lower part is no more than 550mm.
The present invention will overcome on the crash bar of existing truck tail there is no shock absorber, easily cause the deficiency of the injury of knocking into the back, the invention provides a kind of heavy-duty truck rear bumper, on this heavy-duty truck rear bumper, be provided with shock absorber, mortality when reduction roadlice knocks into the back truck, to make exactly the front cross rail of roadlice and front side member participate in rear-end impact endergonic process, exactly will be constant in lorry protecting device for rear lower part lower edge terrain clearance and prerequisite that roadlice front cross rail upper limb height is constant under mortality reduce roadlice and knock into the back truck time.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of novel truck Grard Assy is provided, this truck Grard Assy is a kind of has elastomeric double-deck Grard Assy, comprise bracing frame, on bracing frame, be connected with crash bar, bracing frame top has bolt fixed orifice, on crash bar, be connected with spring, on spring, be connected with Crashworthy plate, crash bar, Crashworthy plate size is identical, the position, four angles of two crash bars respectively has through hole, on Crashworthy plate, be provided with and hole size, four smooth screw rods that position matches, smooth screw rod is through through hole, smooth screw rod can slide in through hole, the end of smooth screw rod is fixed with nut, on Crashworthy plate, be provided with elastic rubber slab, the middle part of bracing frame and crash bar is provided with wire net, the two ends of wire net are separately fixed on bracing frame and crash bar.
In order to address the above problem, the present invention is achieved through technology,
The technical solution adopted for the present invention to solve the technical problems is that a kind of novel truck Grard Assy, comprises bracing frame, with the nut that smooth screw rod mates, big spring, Crashworthy plate, rubber plate, little spring, crash bar A, smooth screw rod, crash bar B, wire net.Bracing frame is fixedly connected with crash bar B, and crash bar B and crash bar A have through hole in identical position, and smooth screw rod pierces in the through hole of crash bar A and crash bar B, and smooth screw rod one end connects with nut, and the other end is connected with Crashworthy plate; Between crash bar A and crash bar B, be connected with big spring, between crash bar B and Crashworthy plate, be connected with little spring; The setting of double-deck crash bar has improved the buffer capacity of crash bar greatly; One end of Crashworthy plate is provided with elastic rubber slab, also plays certain buffering effect; A slice wire net is set between crash bar and bracing frame, when roadlice speed is very high, may crashes anticollision device, now wire net has played the protective action of the 3rd layer;
The setting of the double-deck crash bar of crash bar A and crash bar B, effectively raises the buffer protection effect of crash bar.
Wire net is high tensile steel wire, has certain strength and stiffness, has further improved the protection effect of crash bar.
Between crash bar and Crashworthy plate, utilize screw rod to be connected, increased the intensity of crash bar.
Crash bar one end connects with nut, and the effect of threaded pre-tightening power is better than simple welding effect, and convenient disassembly, is more conducive to maintenance.
Adopted technique scheme, the invention has the beneficial effects as follows:
Double-deck crash bar designs, and effectively raises the buffer protection effect of crash bar; The increase of high-strength steel mesh, very high in roadlice speed, when having destroyed Crashworthy plate, played further protection effect; Crash bar one end connects with nut, and one end is fixed on stay bearing plate, and convenient disassembly is subject to the effect of threaded pre-tightening power, has further increased the intensity of screw rod.
Therefore, the present invention compares with existing crash bar, has outstanding advantage and is: when (1) multilayer proofing has reduced roadlice and has knocked into the back truck, and roadlice personnel's injures and deaths degree; (2) multilayer proofing also prevents that roadlice from piercing the bottom of truck, causes serious loss to truck; (3) design of smooth screw rod has increased the intensity of crash bar greatly, simple in structure, easily manufactured.
A kind of Novel crashproof bar structure provided by the invention, simple in structure, easily manufactured, modulability is strong, the design of double-deck crash bar effectively reduces roadlice and truck personnel's injures and deaths degree, and high-strength steel mesh has further reduced mortality, can widespread use.
