3 terms and units of measurement

3.1 adhesion When the normal load is distributed over the entire contact surface and the sliding friction occurs only in the area of the contact surface, The sum of the tangential forces acting on the contact surface. 3.2 adhesion coefficient The ratio of the normal load to the normal load on the contact surface is the dimensionless quantity. 3.3 vertical load of wheels vertical loadofwheel Refers to the measurement of the adhesion coefficient of the tire components perpendicular to the vertical pressure. Divided by relying on the weight of the wheel parts with weight weight The fixed vertical load of the code weight and the variable vertical load relying on the loading of the positive pressure. 3.4 Roller sliding adhesion coefficient slipadhesioncoefficientofroler When the vehicle wheel of the vehicle is slid on the upper bus of the active drum (wheel is locked), the brake force measured by the brake And the ratio of the gravitational (vertical) load of the wheel. For the amount of dimensionless.

4 Overview

The adhesion coefficient tester is used to measure the drum (flat) surface or inspection path of tires and various test tables for motor vehicles The adhesion coefficient of the surface. The adhesion coefficient tester is usually composed of wheel (frame) frame, tire, sensor, loading device, brake device, display instrument Table and other components. Depending on the loading method, the adhesion coefficient tester is divided into two categories. one is loaded by weight, resulting in a fixed ......
