Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , the deceleration belt of the present invention is composed of a plurality of deceleration block units, the cross-sectional shape of each deceleration block unit in the width and height directions is similar to a trapezoid, the top of the cross-section is a horizontal straight line 2, and the two sides are cosine curves 1 and 3, the projected lengths of the two cosine curves on the horizontal plane have the following relationship: L 1 =L 3 =(0.25~0.58)L. The width of the deceleration block can be L = 500 ~ 700 mm, the height can be H = (0.09 ~ 0.22) L, the length can be (1.5 ~ 1.7) L, and the length of the constant speed section 2 can be L 2 =(0.15~0.35)L. The centerline of the counterbore at bolt 4 is located on the symmetric line in the length direction of the deceleration block, and the horizontal distance from the lowest end of the dec...

Abstract

The invention provides a speed reducer free from rigid impact on a vehicle. The speed reduceris formed by combining a plurality of speed-reducing blocks. The shape of a cross section of each speed-reducing block in the width and height directions is similar to trapezoid; and the top of the cross section is a straight line and two sides of the cross section are cosine curves. The vehicle cannot be subject to rigid impact and cannot generate the bumping phenomenon during passing the speed reducer. Low-speed vehicles can smoothly pass the speed reducer with little shock and bump on the vehicle, a driver, passengers and goods; and vehicles which do not slow down is suffered from flexible impact during passing the speed reducer, wherein the vehicle speed is higher and the impact force is larger. The invention has the advantages of overcoming the rigid impact of the traditional speed reducer on the vehicles and the speed reducer, prolonging the service life of the vehicles and the speed reducer, not only ensuring the traffic safety of roads, but also improving the driving comfort of the low-speed vehicles and embodying the definite rewards and punishment on different vehicles. The speed reducer has simple manufacture and installation and can be used as a generation product of the current road speed reducer.

Description

technical field [0001] The invention relates to a deceleration belt used on roads, in particular to a road deceleration belt which has no rigid impact on vehicles and is comfortable for drivers and passengers to ride. Background technique [0002] In recent years, my country's road traffic industry has developed rapidly, making important contributions to the take-off of the national economy and social progress. But at the same time, the road traffic safety situation is extremely severe, and the number of traffic accidents and the number of deaths are increasing year by year. Among them, motor vehicle drivers speeding is one of the most important causes of traffic accidents. [0003] Laying deceleration belts at highway crossings, industrial and mining enterprises, schools, residential quarter entrances and other road sections that require vehicles to slow down and road sections that are prone to traffic accidents can force passing vehicles to slow down, and to a large exten...
