An emergency avoidance lane for vehicle brake failure on a high-speed continuous downhill road section

Abstract

The invention discloses an emergency escape lane for vehicle braking failure in a high-speed continuous downhill road section. For the existing escape lane, only loose gravel and soil pits are used to decelerate the truck. Due to the inertia effect of the downhill, the speed of the truck is reduced It is difficult to completely reduce the problem within the effective distance. The following solutions are now proposed, including a curved road surface, a lane body is provided on one side of the outer wall of the curved road surface, and one side of the outer wall of the top of the lane body is provided with a first drive. Slow speed tunnel, the top outer wall of the lane body is provided with speed bumps distributed at equal distances, both sides of the top outer wall of the speed bump are connected with first rotating rods through bearings, and the outer walls of the two first rotating rods are The first retarding wheel is equidistantly distributed in the socket. The outer wall of the second retarding wheel at the top center of the speed reduction belt of the present invention has fine friction patterns, and the second retarding wheel will be in a high-speed idling state after the wheel contacts, which further effectively decelerates the vehicle.

Description

technical field [0001] The invention relates to the technical field of emergency avoidance lanes, in particular to an emergency escape lane for vehicle brake failure on a high-speed continuous downhill road section. Background technique [0002] At present, emergency avoidance lanes are emergency escape passages set up for out-of-control vehicles on the road, and are generally set on road sections where accidents are more likely to occur. A complete avoidance lane should be composed of the approach of the avoidance lane, the avoidance lane, the service lane and other auxiliary facilities. Most of the escape lanes built in China can divert out-of-control vehicles from the main line, but they do not guarantee the safety of drivers entering the escape lane, including minor accidents such as scraping, scattered goods, and driver disability or injury. Deaths and other serious accidents happen from time to time. According to experts, some domestic escape lanes do not have approa...

Problems solved by technology

[0003] The existing high-speed continuous downhill road section has the following problems in the emergency avoidance lane for vehicle brake failure: the braking system of the truck has a great relationship with the temperature, and the vehicle will often cause braking during the downhill process due to long-term driving and excessive load. The overheating of the system greatly reduces the braking effect of the braking system. The existing emergency avoidance lanes often only use loose sand and gravel pits to slow down the trucks entering the emergency escape lane. Due to the inertia of the downhill, the speed of the trucks It is difficult to reduce it completely within the effective distance, and the prior art is not easy to solve this type of problem. Therefore, there is an urgent need for a high-speed continuous downhill road section to solve the above problems with an emergency avoidance lane for vehicle brake failure.
