Friction vehicle deceleration area

The utility model relates to a traffic route vehicle running speed controlling means, the safe speed driving device of the speed requirement on the different road surfaces of concretely relates to adaptation, different vehicles. Including inlaying the concave trough -shaped shell who locates the below ground to and be located the inside speed reduction tooth subassembly of casing, the bed that slows down, drive assembly, hydraulic tank, speed valve module. Pass through according to the speed of regulation at the vehicle the utility model discloses a vehicle can not the oscillation generation during deceleration strip, if the vehicle can the oscillation generation when vehicle passed through the deceleration strip not according to the speed of regulation. Can be according to the regulate the speed pre -applied force of valve module of the highway section of difference regulation to obtain the different restriction speed of traveling. 本实用新型涉及交通道路车辆运行速度控制装置，具体涉及适应不同路面的速度要求、不同的车辆的安全速度行驶装置。包括嵌设于地面以下的凹槽状壳体，以及位于壳体内部
