[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

[0057] See attached figure 1 , a number of vehicle speed control devices arranged along the width direction of the road are evenly spaced, and a barrier-free area 10 is formed between adjacent vehicle speed control devices. Normally, the length of the barrier-free area 10 should be slightly longer than the vehicle width; barrier-free The size limit of area 10 requires the driver to make adaptive adjustments before it can intersect with it. When the vehicle is traveling fast, the driver’s adjustment time is limited, and the vehicle cannot be calibrated with reference to the barrier-free area, so the wheel will be more likely Touch the deceleration equipment; when the vehicle passes at a low speed and the vehicle is close to the deceleration equipment, the driver spends more time calibrating the vehicle, and has a higher probability of passing through the barrier-free area to ensure the barrier-free of the vehicle and the advantage of adopting this kind of interval distribution ...

Abstract

The invention discloses a vehicle speed control device for annular seamless transition of a speed limiting road section, comprising a speed sensing mechanism for sensing the descent speed of a lifting table, wherein the speed sensing mechanism comprises a movable frame and a turntable, a lock frame articulated with a base frame is also mounted between the movable frame and the turntable, the movable frame is provided with a braking bulge facing to the lock frame, the lock frame is provided with a trochoid groove matched with the braking bulge, and the lock frame is also provided with skewed teeth b matched with skewed teeth a. When the movable frame clockwise rotates, the braking bulge can slide in the trochoid groove and push the lock frame to deflect to the direction of a braking disc along the articulated part, and the skewed teeth a are meshed with the skewed teeth b; when the lifting table quickly glides, the speed sensing mechanism can make response quickly and limit the continuous glide of the lifting table; and when the lifting table slowly glides, the speed sensing mechanism can allow the lifting table to sink to the maximum position.

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...
