Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a stiffness testing device for a flexible disc of an automatic transmission. Background technique [0002] The flexible disc is a key component of the automatic transmission, which connects the flywheel of the engine with the clutch of the automatic transmission to realize power transmission. Since the flexible disk bears torque load in the torsional direction, it is necessary to ensure its torsional rigidity and torsional strength. At the same time, the flexible disk should be able to produce a certain deformation in the axial direction to eliminate the cumulative dimensional error of the engine and transmission in the axial direction, so its axial The rigidity should not be too large, so as to avoid applying a large pressure or pulling force to the clutch after assembly, causing damage to the clutch. Based on the functional characteristics of the flexible disk, it i...
