Annular seamless transition type vehicle speed reduction device

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...
