ANALYSIS OF UNCONTROLLED WEAR IN THE AREA OFA BELLEVILLE SPRING OF A FRICTION TORSIONAL VIBRATIONDAMPER IN A MOTOR VEHICLE CLUTCH
Abstract
The article describes the problem of excessive tribological wear of a torsional vibration damper built into a single-disc friction clutch of a truck vehicle. In contrast to the controlled, design-based wear of damper’s friction rings, i.e., wear whose kinetics are known and predictable, uncontrolled wear at Belleville spring contact surfaces effects in a premature decrease in the damper’s friction torque and, consequently, loss of durability. As a result of the analyses and experimental work, the causes of accelerated wear were identified. Sets of springs and friction rings from the 10 used vibration dampers that worked under similar operating conditions but with different operating periods were used as the basic research material. The influence of abrasive wear of Belleville springs on their load-deflection characteristic was identified. A comparative analysis of the characteristics of the new spring and the used springs is also presented to illustrate changes in the axial load in the assemblies of the analyzed dampers.
