Problems solved by technology

[0002] The speed bump is a fixed device installed on the road and used to limit the speed of the vehicle. In terms of the current shape of the speed bump, it can be divided into a long strip shape and a disc shape. As far as the existing speed bump is concerned, its original design is to Carry out the speed limit of the vehicle. When the vehicle passes at a high speed, the driver's driving comfort is reduced and the speed is reduced by means of bumps. When the vehicle passes at a low speed or slowly, the fixed speed reduction belt is still It will cause large bumps to the vehicle, and it is easy to scratch the vehicle with a lower chassis

Embodiment Construction

[0025] The vehicle deceleration equipment provided by the present invention can carry out adaptive lifting adjustment according to the driving speed of the vehicle, so as to maintain the blocking posture when the vehicle passes at high speed, reduce the comfort of the driver, and reduce the vehicle speed. When passing at an hourly speed or slowly, the barrier can be gradually eliminated, and the vehicle with a lower chassis can be allowed to pass, and the design is more humanized; in addition, the medium in the present invention refers to a liquid or gas with good flow properties, such as air, carbon dioxide, water, hydraulic oil, etc.

[0026] See attached figure 1 , a number of deceleration devices are evenly spaced along the width direction of the road, and a barrier-free area 10 is formed between adjacent deceleration devices. Usually, the length of the barrier-free area 10 should be slightly greater than the vehicle width; the size limit of the barrier-free area 10, The ...

Abstract

The invention discloses an annular seamless transition type vehicle speed reduction device. The device comprises a moving speed sensing mechanism used for sensing the descending speed of a lifting table. The moving speed sensing mechanism comprises a jacking mechanism and a pipeline communicated with the jacking mechanism, the jacking mechanism comprises a cylinder and a piston which is arranged in the cylinder in a sliding mode and can slide in the vertical direction, and the upper end face of the piston is connected with a piston rod vertically distributed and connected with a pressure exerting plate; the pipeline is composed of an inlet pipe and an outlet pipe which are communicated with a cavity separately; the medium flow in the inlet pipe in unit time is larger than that in the outlet pipe in unit time, the inlet pipe is provided with a one-way valve a used for controlling a medium in the pipeline to flow into the cavity of the cylinder, and the outlet pipe is provided with a one-way valve b used for controlling the medium in the cavity of the cylinder to flow to the outlet pipe. A blocking posture is maintained when a vehicle passes at high speed, the comfort of a driver is improved, blocking can be gradually eliminated when the vehicle passes at low speed, and vehicles with low chassis can be allowed to pass.

Description

technical field [0001] The invention relates to a deceleration device installed on a road, in particular to a deceleration belt that can be raised and lowered. Background technique [0002] The speed bump is a fixed device installed on the road and used to limit the speed of the vehicle. In terms of the current shape of the speed bump, it can be divided into a long strip shape and a disc shape. As far as the existing speed bump is concerned, its original design is to Carry out the speed limit of the vehicle. When the vehicle passes at a high speed, the driver's driving comfort is reduced and the speed is reduced by means of bumps. When the vehicle passes at a low speed or slowly, the fixed speed reduction belt is still It will cause a large bump to the vehicle, and it is easy to scratch the vehicle with a lower chassis. [0003] For this reason, the present invention improves the disc-shaped deceleration belt, provides a deceleration belt that can be raised and lowered, and...
