How important is the rear bumper of a truck? Experimental screen exposure: car 56 km/h speed tail-catching chance of survival close to zero

On the highway, we often go to the faster-speed private car to tail the front of the slower large truck or trailer, and the rear collision-proof beam quality of the truck is not uniform. Private cars often drill under the back of the truck, private car’s front anti-collision beams and girders can not play an effective role in protection, directly let the weakest protection of the A-pillar to withstand the impact, accidents are often very tragic.

It can also be seen that the rear anti-collision beam of the truck plays an important role in the safety of the high-speed traffic of the rear vehicle. Recently, according tomedia reports, IIHS several trailer companies after the improved trailer rear anti-collision beam has been retested.

First of all, all the vehicles tested collided at a speed of 35 mph (about 56 km/h), which is not very fast for the driving family, but even at this speed, the front truck is not equipped with rear impact beams or rear anti-collision beams of poor quality, a collision bend.

For rear tail-end vehicles, whether 30%, 50% or 100% overlapping collisions, the driver’s chances of survival are almost zero.

It is reported that, before, IIHS used the Chevrolet Myribo as a rear tail-end vehicle, has 56 kilometers per hour, 30% of the overlapping collision tailing Sage, Utility and Hyundai trailer, the results have failed, the dummy driver “heroic sacrifice.”

And from the test dynamic can be seen, after the tailing, trailer’s rear anti-collision beam on the bend, did not play a buffer effect, Mei Ruibao’s A-pillar directly hit the trailer’s most strong carrier underboard beam, a bend break, directly the dummy “head” into the back, the accident is very “severe”.

Modern trailer test failed motion

In the trailer rear anti-collision beam vehicles retested by IIHS, only the improved anti-collision beams of the modern trailer and the Vanguard and Wabash trailers that took part in the first test were tested.

Experimental results show that the rear vehicle at 56 km/h to carry out tailing, the improved modern trailer rear anti-collision beam, effectively resist the rear rear tail-chasing vehicle, did not touch the vehicle A-pillar trailer, the dummy “comrade” also survived.

Modern trailer test success comparison chart

However, the Rear Collision of vanguard and Wabash trailers, which were tailed at 56 km/h by the rear vehicles, was tailed by 50 per cent overlap and 30 per cent overlap, respectively, and both ended in failure.

The experimental results also confirm that the rear anti-collision beam of the truck has an important safety protection effect for the rear-end vehicle, and can even decide the life and death of the rear car.

Therefore, in addition to calling on truck manufacturers to pay attention to the quality of the rear anti-collision beam, but also remind drivers, high-speed driving, avoid driving behind the truck, once the unfortunate tailgating accident, the consequences of the accident will be very serious.
