Description

TECHNICAL FIELD

[0001] The utility model relates to the field of emergency escape lane blocking cable, more specifically, relate to an emergency deceleration system for highway vehicle. BACKGROUND

[0002] With the gradual perfection and convenience of our country high speed traffic hub facilities, highway traffic volume is also growing. The vehicle driving speed on the highway is not only fast but also relatively dense, and sometimes inevitably there will be a vehicle mechanical failure resulting in vehicle braking deceleration. Therefore, the escape lane is usually built on the steep downhill section or sharp turn section of the highway, and the emergency deceleration system is installed to assist the vehicle in emergency braking deceleration, so as to avoid causing casualties or property loss.

[0003] Although the existing emergency deceleration system has many advantages, but its blocking cable usually adopts the structure form of blocking with steel cable. The blocking cable structure form of blocking with steel cable is not convenient to realize directional pulling out when being pulled out because the width of steel cable is small and the contact area with the reel is small. Therefore, it is not easy to control the impact direction of the vehicle when blocking the vehicle, and it is not convenient to use. At the same time, the steel cable is usually twisted by multiple steel wires. It usually needs a lot of effort to tightly and uniformly wind the steel cable on the reel, which increases the difficulty of installation of the steel cable. Therefore, we propose an emergency deceleration system for highway vehicle to solve the above problems. SUMMARY

[0004] 1. Technical problem to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an emergency deceleration system for highway vehicle. Although the blocking cable in contact with the vehicle is set to the structure form of steel cable, the section to be pulled out to realize deceleration is set to the structure form of steel belt, replacing the structure form of steel cable in the whole section of the existing blocking cable. The width of the steel cable is larger, and the contact area with the outer wall of the sleeve joint section is larger when being pulled out, so that the steel belt can be pulled out in a directional manner, assisting the steel cable to block the vehicle in a directional manner, reducing the probability of deviation or even rollover of the vehicle during blocking.
