000014105 520__ $$2eng$$aTwo dynamic phenomena in automotive transmissions are investigated, which both arise while shifting. The first one is the radial displacement between the rotation axes of the clutch’s discs. The second one is friction induced flutter provoking vibrations, noise and sometimes significant durability problems. The interaction between the sliding clutch and the helical gearing in the transmission is of crucial importance for both phenomena. A minimal model of a gearbox incorporating a flexible clutch disc is presented and the relevant instability mechanisms are discussed. The stability analysis based on linearization is compared to transient simulations of the complete nonlinear system, which enable to identify the main mechanisms limiting the vibration amplitude: stick-slip transitions within the clutch due to strong rotational vibrations, contact losses between the clutch discs and between the gears due to axial vibrations. It is shown that complex sequences of these events can take place within one limit cycle.
