Deceleration lane

Abstract

The invention belongs to a road-administration facility, and particularly relates to a lane which can be used for slowly decelerating a vehicle which is out of control. The lane comprises multiple horizontal supporting rollers, wherein the multiple horizontal supporting rollers are arranged in a mutually parallel manner; each supporting roller is assembled in a same horizontal plane; the upper roller surfaces of the supporting rollers are combined into a bearing surface through which the vehicle runs; each supporting roller is assembled to be capable of independently reciprocating along the vertical direction; further, a group of independent elastic units is arranged below each supporting roller; the elastic units are assembled to be that the elastic units can generate upward elastic force to the supporting rollers when the supporting rollers are pressed to downward move. According to the lane, the kinetic energy of a car body is gradually absorbed by utilizing the elastic units below the supporting rollers; the speed of the vehicle can be linearly decreased progressively; thus, the impact on a person in a car is lightened.

Description

technical field [0001] The invention belongs to road administration facilities, in particular to a lane capable of slowly decelerating out-of-control vehicles. Background technique [0002] Vehicle loss of control is one of the main causes of major traffic accidents, especially when driving on high-speed highways, the speed of the vehicle is generally around 100-120km / h, once the vehicle loses control at such a high speed, it will lead to serious consequences. The loss of vehicle control is generally caused by two reasons: tire blowout and brake failure. For a blowout, if the driver has rich driving experience, taking appropriate emergency operations can still reduce the damage to a certain extent. , the driver can only wait for the vehicle to decelerate naturally, or use the avoidance lane to decelerate urgently. The traditional escape lane is generally made of sand and gravel. After the vehicle enters the escape lane, the fluidity of the sand and gravel is used to absorb ...

AI Technical Summary

Problems solved by technology

The traditional escape lane is generally made of sand and gravel. After the vehicle enters the escape lane, the fluidity of the sand and gravel is used to absorb the kinetic energy of the vehicle body, thereby decelerating the vehicle. However, in practical applications, the vehicle at high speed Underrushing into the gravel driveway will still produce a large instantaneous impact force, and its buffering effect is limited, which makes it difficult to ensure the personal safety of the driver, and the gravel driveway will cause greater damage to the vehicle, and the vehicle is difficult to pull out if it is trapped in the gravel , which brings inconvenience to the handling of subsequent accidents
