Experimental determination of a disc spring stiffness to calculate the reserve coefficient of a diaphragm clutch
Abstract
The acceleration process during traction-dynamic calculation is divided into several stages, the most difficult of which for mathematical description is starting. The article is devoted to the study of diaphragm clutches used on cars and trucks. When constructing an acceleration graph for a car with a traditional manual transmission, five assumptions are made, and one of them concerns the coefficient of safety of the friction clutch, when used, several misconceptions arise: the clutch characteristic is the friction torque; table values are given without indicating the source; do not distinguish between dynamic and static safety factors; When shifting along the external speed characteristic, the safety factor changes. The authors note that the main problem is the lack of information about the real values of the friction torque. An experiment was conducted to determine the stiffness of a disc spring for diaphragm clutches with mileage. Conclusions are formulated about the influence of various factors on the clutch safety factor.
