Description

Technical Field

[0001] The utility model relates to the technical field of road surface friction coefficient detection, in particular to a water spraying amount control device for a single-wheel type lateral force coefficient detection vehicle. Background Art

[0002] The lateral force coefficient of the road surface can directly reflect the anti-slip performance of the road surface. Insufficient anti-slip performance of the road surface will greatly increase the risk of side-slip of vehicles traveling at high speed, and in severe cases, it may lead to traffic accidents. Therefore, it is very necessary to detect the lateral force coefficient of the highway pavement. Using a standard friction coefficient measuring vehicle, when the measuring wheel forms an angle between 7.5° and 20° with the driving direction and travels on a wet road surface at a certain speed, the ratio of the lateral frictional force received by the test wheel to the load acting on the test wheel is called the lateral force coefficient, also known as the side force coefficient (dimensionless), abbreviated as SFC. This method of measuring the lateral force coefficient is called the deflecting wheel trailer method. Its advantage is that it does not interfere with traffic during measurement, can be continuously and quickly measured, and this method is commonly used in high-grade highways to evaluate the anti-slip performance of the road surface.

[0003] When the existing detection vehicle sprays water on the test wheel and the road surface, the water spraying device is usually fixedly connected to the detection vehicle, and only the orientation of the water spraying nozzle can be simply adjusted, and the adjustable range is limited. At the same time, the water spraying amount cannot be controlled and adjusted during the water spraying process, which affects the detection effect. Summary of the Utility Model
