Protective fence is to be made of metal and car body is all rigid contact, and collision is big to the damage of vehicle and personnel.
1, for protective fence due to self structure, intensity is poor, is easily damaged in collision.
2, when collision occurs, often all standing, energy can not discharge vehicle, and huge inertia can cause vehicle that side occurs
Turn over, cause serious traffic accident, such situation on large and medium bus and high capacity waggon presentation it is more obvious.
3, buffer gear is single, the drum buffering mechanism occurred in the prior art when providing certain guiding role, by
In still remaining larger rigidity, guidance quality is poor, flexible buffer unobvious.
4, more difficult in racetrack portion buffering.
Lead to vehicle rollover in conclusion guardrail presence in the prior art is easily damaged, impact energy can not discharge, delay
Punch mechanism is single, guidance quality is poor, racetrack portion buffering is difficult and not the characteristic of flexible buffer the problem of.
Utility model content
