Speed reducer for road

Abstract

The invention discloses a speed reducer for a road, which is used for speed reduction of a vehicle running on the road, particularly, speed reduction in a downhill road. The speed reducer comprises a speed bump body which is a rubber speed bump body with an elastic buffer function, wherein an upper inclination part and a lower inclination part are arranged on two sides of the rubber speed bump body respectively, the inclination direction of the upper inclination part is identical to the direction when the vehicle runs towards the rubber speed bump body, the inclination direction of the lower inclination part is identical to the direction when the vehicle runs away from the rubber speed bump body, mounting holes are formed in the upper inclination part and the lower inclination part, and connecting bolts are arranged in the mounting holes and used for fixing the rubber speed bump body on the road. The device can realize good speed reduction and control effects and enables the vehicle which is out of control during downhill driving to rapidly stop, a vehicle driving downhill to stably drive and a vehicle at a tunnel entrance to slow down, and the prominent problems that the number of conventional emergency lanes is limited, a vehicle running on a long downgrade road easily fails to brake, the speed of the vehicle at the tunnel entrance is too high and the like can be solved.

Description

technical field [0001] The present invention relates to a road traffic facility, more specifically, to a road deceleration device. Background technique [0002] Road safety, especially the driving safety on the long and downhill sections of the expressway, has always been paid attention to. However, due to the limited geographical location of the construction of escape lanes, the number of escape lanes on the long and downhill sections is limited, so that once a vehicle out of control It is difficult to be controlled if you miss the avoidance lane. In addition, because the existing avoidance lane does not have the function of avoiding danger in the true sense, but only manages to allow the out-of-control vehicle to park within a certain range, even if the out-of-control vehicle enters the avoidance lane , It is also possible that the vehicle is seriously damaged and cannot play the role of hedging. [0003] In addition, the existing avoidance lane is only a response to the ...

AI Technical Summary

Problems solved by technology

By installing the above-mentioned road deceleration device on the main road (travel lane) of the long downhill section to form a stable speed lane, the downhill vehicle can maintain the speed without braking, so as to solve the problem of vehicle brake failure on the main road

The above-mentioned road deceleration device can be installed in front of the tunnel entrance to form a deceleration lane, and vehicles, especially small vehicles, can be properly decelerated to solve the problem of excessive speed at the tunnel entrance
