Description
Technical Field
The utility model relates to a road detection technology field especially relates to an on-vehicle road roughness check out test set's fixing device.
Background
The flatness is one of the important indexes of the pavement construction quality and service level. It is an index for measuring the unevenness of road surface intermittently or continuously by a predetermined standard gauge. The flatness of the road surface is in certain relation with the flatness of each structural level of the road surface, namely, the leveling effect of each level is cumulatively reflected on the surface of the road surface, and the uneven surface of the road surface directly contacts with vehicles and the atmosphere, so that the driving resistance is increased and the vehicles generate additional vibration. The vibration causes bumping, affecting speed and safety of driving, driving stability and passenger comfort, and exerts impact force on road surface, thus aggravating damage to road surface and automobile parts and abrasion of tires, and increasing fuel consumption. Moreover, uneven road surfaces accumulate rain water, accelerating the destruction of the road surface. Thus; the detection and evaluation of the flatness are very important links of the construction and maintenance of the highway.
The reaction type vehicle-mounted flatness measuring method generally needs to fix equipment on a rear suspension, the original fixing method is not beneficial to eliminating the vibration of the vehicle, and the measuring error is large when the vibration of the vehicle is large.
