Elastic damage-free speed hump for vehicles

Abstract

The invention discloses an elastic damage-free speed hump for vehicles. The speed hump comprises two pressing plates which are connected with a connecting rod mechanism so as to be folded and hunched; two connecting rod groups which are hinged to each other are arranged at the bottoms of the pressing plates; one end of one connecting rod of one connecting rod group is hinged to the corresponding end of one connecting rod of the other connecting rod group through a pin bolt, and the other end of each connecting rod is hinged to a sliding block through a connecting pin; each sliding block slides along a sliding chute formed in a sliding chute base which is fixedly arranged; a compression spring which is connected with the corresponding sliding block is arranged in each sliding chute base. The speed hump disclosed by the invention is simple in structure, and convenient to maintain; under the premise that the road safety is guaranteed, the driving and riding comfort of drivers and passengers can also be achieved; the damage caused by the speed hump to vehicles is reduced; the production cost and the using cost are reduced; the speed hump can be extensively generalized and applied on various roads which need the speed hump.

Description

technical field [0001] The invention relates to the technical field of road traffic facilities, in particular to an elastic and non-damaging vehicle deceleration arch. Background technique [0002] At present, the deceleration arches that are used to make vehicles slow down at road intersections are all rubber products or cement pier arches, although they can play the role of making vehicles slow down. However, rubber products are not very durable, and they are easily damaged and invalidated by repeated rolling by heavy vehicles; while cement arches are made manually on site, it is difficult to meet the requirements of the deceleration arch specification. [0003] For example, the Chinese utility model patent with the application number "201220308020.1" discloses a "shock-absorbing speed bump". , and connected with the hydraulic cylinder, the pressure caused by the vehicle passing through the speed limit plate is buffered by the hydraulic cylinder, which can effectively avo...

AI Technical Summary

Problems solved by technology

However, there are two deficiencies in this patented technology: firstly, the hydraulic cylinder is arranged under the speed limiting plate, because the environment on the road is not suitable for the use of the hydraulic cylinder, in order to reduce the impact of the road environment on the operation of the hydraulic cylinder , the hydraulic cylinder needs to be sealed under the road surface, which is very difficult to maintain; second, the production cost of the hydraulic cylinder is relatively high, combined with the first point of use cost, it is difficult for this technical solution to be widely used in road traffic to promote the application
