Expressway energy dissipation reducer, device and system

Abstract

The invention provides a highway energy dissipation speed reducer, speed reducing device and speed reducing system. The highway energy dissipation speed reducer comprises a pushing end head, a mounting section, a diffusion section, a reciprocating part and a high-pressure part, wherein the pushing end head can be installed in a front portion in a back and forth mode, and a rear portion is used forlimiting the pushing end head; the diffusion section communicates with the rear portion of the mounting section, and the inner diameter of the diffusion section is gradually expanded; the reciprocating part comprises a reciprocating section, a first porous plate, a second porous plate, a first elastic piece, a plurality of downstream reciprocating units and a plurality of backflow reciprocating units, a plurality of downstream holes are formed in a main body region of the first porous plate, and a plurality of backflow holes are formed in a peripheral region of the first porous plate, the second porous plate is the same as the structure of the first porous plate, the downstream reciprocating units comprise downstream blocking beads and downstream elastic pieces, the backflow reciprocatingunits comprise backflow blocking beads and backflow elastic pieces; and the high-pressure part comprises a high-pressure section, a separation pressing plate which can be movably arranged at the front portion of the high-pressure section in a reciprocating manner, and inert high-pressure gas filling high-pressure cavity defined by the high-pressure section and the separation pressing plate.

Description

technical field [0001] The invention belongs to the technical field of highway collision avoidance, and relates to a highway energy dissipation reducer, a highway energy dissipation deceleration device containing the expressway energy dissipation deceleration device, and a highway energy dissipation deceleration device containing the expressway energy dissipation deceleration device system. Background technique [0002] The traffic hazard caused by the failure of the brakes caused by the high temperature on the continuous long and downhill section of the expressway has always been a pain point for expressway safety. The vehicle brakes frequently on the downhill of the expressway, so that the friction lining and the brake hub are often in a state of heat. If the temperature is too high, the brake will fail or the braking efficiency will be reduced too much, which will directly lead to the loss of control of the vehicle and cause the vehicle to rush out of the road. Vicious t...

Problems solved by technology

This kind of device does not take into account the interference of the out-of-control vehicle to other normal vehicles, that is, when the out-of-control vehicle returns to the original driving track, it will affect other vehicles. At the same time, the guardrail is difficult to apply to the collision of large high-speed out-of-control trucks
