一种新型减速带装置的设计

Design of New Speed Control Hump Device

为了减少震动和噪声,设计了一种新型减速带装置。当车辆高速驶过减速带装置时,减速带面板瞬间不会下降,保持其应有的作用;而当车辆以低速驶过时,减速带面板在一对扇形齿轮的作用下缓慢下降,直至与地面平行,将车辆冲过减速带时的刚性冲击转变成柔性冲击,从而增强车辆通过的平稳性,减少震动和噪声;车辆通过后,复位弹簧作用使减速带复原;装置还实现了将车辆冲击减速带产生的能量转化成电能,存储利用。

The vibration and noise are caused by the unreasonable design of current speed control hump devices. This paper designs a new speed control hump device. When a car drives through the speed control hump with high speed,its top does not decline in a short time, so its function is etil kept;however,when a car drives through it with low speed,its top declines slowly til it is in paral el with the ground,and the rigid impact is turned into the flexible impact, so the stability of the car driving can be enhanced. After the car driving through. the top of speed control hump rises to the reinstatement with the effect of the reset spring. In this process, the energy produced by the impact of the car and speed control hump is transfered into electric energy,which is stored to the battery.
