Automobile transmission torsion oscillation damper comprises first and second friction elements with friction surfaces at different axial levels, axial distance between surfaces compensated by sloping friction surfaces passage segments

摘要

The torsion oscillation damper comprises a first friction element (37) with friction surfaces (98,108) having different axial levels. The axial distances between the friction surfaces are compensated by passage segments (100) also useable as friction surfaces with an axial slope. The first friction element comprises two connected components (80,94) of different materials. One (94) carries the passage segments with the friction surfaces. A second friction element (39) also comprises passage segments (120) useable as friction surfaces with an axial slope. The ends of the peripheral side opposite this element's friction surfaces (118) are adjacent to the connection surfaces (122) whose axial distance relative to the friction surfaces of the first element exceed the axial distance (D) between the friction surfaces of the first and second engaging friction elements.
