Description
Technical Field
The utility model relates to a road safety facility field especially relates to a gentle fast board for speed reduction. In some special road sections, such as doorways of schools, hospitals and the like, such as villages, toll stations, continuous curves or downhill road sections, in order to guarantee safe driving of motor vehicles and pedestrian safety to the maximum extent, forced deceleration belts are arranged on the road sections, and the purpose of forcing the motor vehicle driver to decelerate slowly is achieved, so that the purpose of safely passing the motor vehicles is achieved.
Background
Most deceleration strips in the prior art are hard car stoppers, and the functions of the deceleration strips do not achieve the effect of deceleration. Due to the arrangement of the radian and the width of the speed bump, the vehicle can only run at a speed of 0.5 kilometer per hour, and hard bump is not caused. Otherwise, the deceleration strip is uniformly and rigidly bumpy, so that drivers and passengers who pass through the deceleration strip have extremely uncomfortable feelings, and particularly, when the old, patients, pregnant women and children are carried on the deceleration strip, the deceleration strip is likely to cause body damage and is extremely humanized; in addition, the deceleration strip can cause irreversible damage to a motor vehicle suspension system after being frequently used; meanwhile, the scales of buses, trucks and slow-moving vehicles are not considered in the conventional speed bump, so that all vehicles suffer from jolt as usual.
The existing speed reduction speed retarder has the following defects:
1. on domestic roads, rubber and concrete entity deceleration strips are the most common, the rubber deceleration strips are newly produced rubber products, the rubber deceleration strips are not recycled, the production process is polluted, and water resources are wasted in the vulcanization and cooling processes (90% of enterprises adopt disposable water for cooling). The domestic rubber deceleration strip is easy to pollute the air. During the use process, the pungent smell is released.
2. The cement deceleration strip has no uniform system, the chassis is easily damaged by the fact that the slope surface is too high, and the deceleration effect is poor if the slope surface is too low. The shock resistance is poor, and the car can have strong jolt through the cement deceleration strip.
3. The deceleration function of the domestic deceleration strip on the high-grade vehicle is very small; the low-grade vehicle is required to step on the brake, which wastes energy. Four or five deceleration strips are installed on a common road section, great inconvenience is caused, great damage is caused to a vehicle, inconvenience is brought to a driver and passengers, and safety of the road section can be further reduced due to unscientific arrangement.
4. The structural design of the speed bump is unreasonable. The deceleration strip is designed to decelerate the vehicle and improve the safety, but the domestic deceleration strip has the length of about 35cm, the height of 30-100mm and no buffer zone. Firstly, the design is easy to cause damage to the vehicle, the light person can hurt the shock absorbing spring, and the heavy person can hang the oil pan. Secondly, the tire is the only part on the car that directly contacts with the ground, and the deceleration strip structure of width can form a pressure to the side of tire like this, causes the atress of child wall, and the child wall is a weakest position in the tire again, and such deceleration strip causes the condition such as tire bulge. And thirdly, the suspension damage is caused, the tire does not have too much shock absorption capacity, most of shock can be absorbed by the suspension, so that the loss of certain degree can be brought to each suspended part by the domestic deceleration strip, and the suspension durability can be greatly influenced after long-term storage.
5. When a vehicle passes through the speed bump, abnormal noise often occurs.
6. Domestic deceleration strip bearing is low, and crashworthiness is not good, and is yielding after long-term the use, damages, needs periodic replacement, and the replacement cost is high.
7. The deceleration strip is outstanding and narrow, has no buffer zone, is easy to cause severe vibration, forms severe jolting feeling to passengers, is easy to cause adverse effects on old people, infants and pregnant women, and is especially easy to induce premature rupture of membranes in pregnant women in late pregnancy.
