Dynamometer PKRS - 2U trailer
The device of control of flatness and coupling represents the one - wheeled trailer towed by the car with the special coupling device installed on it. Thanks to parallelogrammny hitch, the outside frame constantly keeps situation parallel to traffic - bearing surface surface.
The trailer is used as a part of mobile laboratory KP - 514SMP or any other vehicle supplied with the on - board computer and capacity with water.
The coupling coefficient at full blocking of wheel with forced water supply for creation on covering of the highway of water film 1 mm thick is measured.
Registration of indications of primary sensors is made by the onboard computer system with measurement data output on the display. The indicator of flatness of covering of roads is determined by the total size of movement of wheel of the trailer of rather inertial mass of its body per unit length of the road.
