Abstract
The utility model relates to a freight train rear defence bores device, disclose one kind can the altitude mixture control and possess buffer function's freight train rear defence bores device. This rear defence bores the device and includes upper bracket, round pin axle, attenuator, lower carriage, crossbeam and spring. The beneficial effects are that when the barrier was crossed to the vehicle, the barrier can bore the rear defence and boost to the vehicle passes through, when the experience car knocks into the back, the effect of dual energy -absorbing will be exert to spring and attenuator on the rear defence bores, alleviate collision impact power in the at utmost to the safety of protection vehicle.
Description
Technical field
The utility model is related to vehicle collision security technology area, and in particular to Anti-drilling device after a kind of lorry.
Background technology
It is a kind of important safety device, especially lorry that automobile rear is bored, because its chassis it is higher, once by car
Knock into the back, if without the drill-through height of rear anti-drilling or rear defence, may result in car and pierce lorry bottom, so as to produce larger wound
Evil.Rear defence it is drill-through it is low vehicle departure angle can be made to diminish, affect vehicle it is cross-country;The drill-through height of rear defence does not then meet national standard, rises not
To anti-drilling effect;It is anti-drilling after simultaneously to have certain buffer capacity, such that it is able to buffer impact force after collision occurs.It is existing
Have rear anti-drilling mostly fixed on market, it is highly non-adjustable and do not possess crusherbull zone effect.
In order to solve this problem, the utility model provides a kind of goods that can highly adjust and possess pooling feature
Anti-drilling device after car, the device have alterable height, dual-stage buffer, simple structure, it is easy for installation the features such as.
The content of the invention
For deficiency of the prior art, the utility model aims to provide one kind and can highly adjust and possess buffering work(
Anti-drilling device after the lorry of energy.
The technical scheme that the utility model is adopted, including upper bracket, bearing pin, damper, lower carriage, crossbeam and spring.
Upper bracket is arranged on automobile frame by bearing pin;Damper one end is arranged on vehicle frame, and one end is connected with upper bracket, damper
It it is 45 °~60 ° with upper bracket angle;Lower carriage is connected to upper bracket bottom by bearing pin;Crossbeam is arranged on lower carriage lower end;Bullet
Spring is arranged in the installing hole between crossbeam and lower carriage.
Preferably, described upper bracket lower end is provided with limited block so that lower carriage can only rotate backward around bearing pin, it is impossible to
Front rotation;
Preferably, described damper is fluid pressure type, and inside is provided with stopping means;
Preferably, described lower carriage lower end is provided with spring mounting hole;
Preferably, described crossbeam is trench structure.
The beneficial effects of the utility model are:Upper bracket, lower carriage can rotate backward around bearing pin, be provided with crossbeam spring and
Damper double buffering device, has the advantages that alterable height, dual-stage buffer, safe.
Description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that lower carriage installs profile with crossbeam;
In figure:1st, vehicle frame;2nd, upper bracket;3rd, bearing pin;4th, damper;5th, lower carriage;6th, crossbeam;7th, spring.
Specific embodiment
The following is specific embodiment of the utility model and combine accompanying drawing, further is made to the technical solution of the utility model
Description.
As shown in Figure 1 and Figure 2, a kind of Anti-drilling device after lorry, including upper bracket 2, bearing pin 3, damper 4, lower carriage 5, horizontal stroke
Beam 6 and spring 7.
The upper bracket 2 is arranged on automobile frame 1 by bearing pin 3, and upper bracket 2 can be rotated before and after bearing pin 3.
The one end of the damper 4 be arranged on vehicle frame 1 on, the other end is connected with upper bracket 2, damper 4 in upper bracket forward
Apply damping force during rotation;Stopping means is provided with inside damper 4, when damper 4 is compressed into extreme position, stopping means
Work, damper 4 is changed into rigidity.
The lower carriage 5 is connected to the bottom of upper bracket 2 by bearing pin;Because the lower end of upper bracket 2 is provided with limited block so that lower
Frame 2 can only rotate backward around bearing pin, it is impossible to rotate forward.
The crossbeam 6 is arranged on the lower end of lower carriage 5;The spring 7 is arranged on the installing hole between crossbeam 6 and lower carriage 5
It is interior.
Specific work process is as follows:When the cross-country barrier of vehicle is too high block after anti-drilling crossbeam when because it is rear it is anti-drilling under
Support can be rotated around bearing pin, and barrier can hold up lower carriage, allow vehicle to pass through;When vehicle meets with to knock into the back, rear
Vehicle can hit crossbeam, and after kinetic energy is clashed into spring buffer part, crossbeam promotes lower carriage and upper bracket to travel forward, now
Damper produces damping action and absorbs portion of energy, the stopping means when damper is extruded into extreme position, in damper
Function to, damper is changed into rigidity, while impact force is passed into vehicle frame.
Although the above-mentioned accompanying drawing that combines is described to the specific embodiment of the present invention, not the utility model is protected
The restriction of scope is protected, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, this area skill
Various modifications that art personnel make by need not paying creative work or deformation are still within protection scope of the present invention.
