Description
Technical field
The invention belongs to auto body attachment technique field, the anti-multi-buffer anticollision device that knocks into the back of specifically a kind of lorry.
Background technology
According to Public Security Department of Ministry of Public Security vehicle in 2011 and steerman management agency statistics, 210812 of the road traffic accidents that the whole nation relates to personal casualty cause 62387 people death altogether, and the load carrying vehicle accident is more outstanding, accounts for 71.8% of the operational accident of whole production.See from the major accident reason, drive over the speed limit, drunken driving, fatigue driving remain the chief reason that causes traffic accident multiple.The death by accident number that causes of particularly driving over the speed limit accounts for 14.2% of whole death tolls, and from the accident place, road conditions see that the accident of express highway still is the trend of rising.Because it is comparatively frequent that the too fast rear-end collision accident that causes of the speed of a motor vehicle takes place, and especially descends at relatively poor environment of driving sight line such as rain, snow, dense fog, nights, occurs the traffic accident of rear-end collision more easily, causes the loss that can't retrieve for people's lives and properties.
In rear-end collision, the car truck that knocks into the back is the higher accident form of proportion, also is a kind of accident form that leads to grievous injury easily simultaneously.Because the vehicle body of truck is higher, small passenger car top is weakest link, and car is easy to get into below the truck, can make the A post of small passenger car directly receive serious crimp, even cutting.And when knocking into the back, the structure of small passenger car body structure has been brought into play not energy-absorbing and the effect of resisting distortion because of the anticollision device of bump less than the lorry afterbody, and then driver and crew in the car are caused serious injury.At present, comprise that a lot of countries and regions of the U.S., Europe and China all require truck to install the bottom collision prevention girders additional at afterbody, when preventing to knock into the back car get into truck below.
Though present high capacity waggon is equipped with anticollision device in tailstock bottom, comes in every shape, there is not concrete unified standard, undercapacity has satisfied not bump.The collision prevention girders installation site of general lorry is higher, and car still can pierce under the car, and the harm meeting is bigger on the contrary not only not have crash-proof effect.Some collision prevention girders still is hinged underslung, performs practically no function, so in rear-end collision, still can cause serious mortal injury, this also will more and more receive publicity on the safe design of automobile from now on.
Summary of the invention
In order to solve existing existing the problems referred to above of lorry anticollision device; The invention provides the anti-multi-buffer anticollision device that knocks into the back of a kind of lorry; Suffered bump played preferably buffering effect and can stop small passenger car to pierce the lorry bottom when it can knock into the back lorry to small passenger car; Ensure driver and crew's safety, effectively reduced amount of vehicle damage and property damage.
The present invention for realizing the technical scheme that above-mentioned purpose is taked is:
The anti-multi-buffer anticollision device that knocks into the back of a kind of lorry; Wherein: the rear portion at the lorry crossbeam is connected with a crashproof framework through bearing pin, is provided with one in the bottom of boxcar and hangs fixed beam, is provided with a rubber cushion bumper beam in the front portion of crashproof framework; On crashproof framework, also be provided with spring pressure-reducing cushioning device and damping wire rope; Said spring pressure-reducing cushioning device is made up of spring, spring strut, length of spring compressed bar and nut, and spring is installed in the spring strut, and the length of spring compressed bar is through the centre of spring; The upper end of length of spring compressed bar is fixed through nut; The lower end of length of spring compressed bar extends to the outside of spring strut, and the upper end of spring pressure-reducing cushioning device is fixed on through bearing pin and hangs on the fixed beam, and the lower end of length of spring compressed bar is fixed on the rubber cushion bumper beam through bearing pin; The upper end of said damping wire rope is fixed on through bearing pin hangs on the fixed beam, and the lower end of damping wire rope is fixed on the rubber cushion bumper beam through bearing pin.
Further, be coated with one deck hollow rubber pad at said rubber cushion bumper beam.
The present invention adopts technique scheme, is connected through bearing pin between anticollision device and the lorry crossbeam, and the rubber cushion bumper beam surface of anticollision device is covered with high resiliency hollow rubber pad, the first order buffering during as collision, and bearing pin is installed in the rear portion of lorry crossbeam; Below the compartment of lorry tail end, install and hang fixed beam, hang and be connected with spring bumper and damping wire rope between fixed beam and the anticollision device, spring bumper is as the second stage buffering after colliding; After anticollision device was clashed into, spring was compressed energy-absorbing and is compressed to when closing on ultimate limit state at it, and the damping wire rope is tightened up, and this moment is simultaneously stressed with spring bumper, carries out multi-buffer and shock damping action, stoped small passenger car to pierce the lorry bottom.Because just there is crashproof and energy-absorbing effect the front portion of small passenger car own, crashproof depth of beam should be consistent with the height of the anticollision device of small passenger car, so short rear anti-crash device can actv. stops small passenger car to pierce the afterbody of lorry, reduces personnel's injures and deaths.
If will produce bigger impulsive force when the speed of small passenger car is too high, under worst situation, possibly produce destruction to spring bumper and damping wire rope; When spring bumper and damping wire rope all lost efficacy; The collision prevention girders of anticollision device will drop on the ground voluntarily, and still can form a wedged gap with truck chassis this moment, and small passenger car will be stuck in this triangulation reference district; There is the rigid construction of engine bin and the portion of car predecessor of small passenger car to be out of shape and absorbs Impact energy; And small passenger car can not pierce lorry bottom, and the driver and crew in the car have been played good protection, avoided injures and deaths and greatly degree minimizing the damage rate of vehicle.In a word, the anti-multi-buffer anticollision device that knocks into the back of lorry of the present invention can carry out multi-buffer and shock damping action to the small passenger car that knocks into the back; Effectively avoid driver and crew's the injures and deaths and the loss of property; The present invention is simple and practical in addition, easy for installation in addition, the crashproof advantage such as effective of multi-buffer.
