Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly relates to an infinitely variable damping clutch driven disc assembly. Background Art

[0002] In traditional automotive clutches, the driven disc assembly generally requires a design with torsional damping function. The realization of the torsional damping function is achieved through a number of evenly distributed torsional damping springs. The torsional damping springs can achieve damping with a first-level torsional stiffness. If the active part (i.e., the hub connected to the first shaft of the gearbox) and the passive part (driven disc) in the clutch are designed with a specific angular deviation in the relative phase window, the damping functions with second-level and third-level torsional stiffness can be achieved. The above-mentioned torsional damping structure has limitations and uniqueness in damping limits. The existing infinitely variable damping clutch driven disc assemblies do not have strong seismic resistance and are easily damaged to the clutch driven disc assembly.

[0003] For traditional infinitely variable damping clutch driven disc assemblies, most of their structures are unreasonably arranged, do not have strong seismic resistance, are easily damaged to the clutch driven disc assembly, resulting in a high repair rate of the clutch driven disc assembly, a short service life of the clutch driven disc assembly, low precision during the operation of the clutch driven disc assembly, being not safe and reliable enough, not firm and durable enough, and having poor practicability.
