Abstract: Aiming at the test method of automobile multi-wedge belt friction, through the force analysis of multi-wedge belt cross section, the formula for calculating the equivalent friction coefficient is es-tablished, and the influence rule of tension on the equivalent friction coefficient is obtained. A test device for measuring the equivalent friction coefficient of automobile multi-wedge belt is designed, and the influence rule of different tension force on the equivalent friction coefficient is tested. The experimental results show that with the increase of tension force, the equivalent friction coefficient increases. Additionally, with the increase of equivalent friction coefficient, the experimental results are in good agreement with the theoretical analysis, which provides a basis for the design of multi-wedge belt multi-wheel drive.
