Problems solved by technology

Although the dual-mass flywheel has good damping performance as a whole, its structure does not have a multi-stage variable damping mechanism with adjustable damping, which cannot better optimize the damping effect of the vehicle under various working conditions

Abstract

The invention discloses a flywheel shock absorber integrating multi-stage variable damping. The absorber comprises a flywheel sub-assembly, a shock absorber sub-assembly and a multi-stage variable damping sub-assembly. A flywheel outer ring of the flywheel sub-assembly is provided with a plurality of step damping friction pairs which are radially arranged, a variable damping friction pair and a variable damping control surface. The multi-stage variable damping sub-assembly is assembled to realize step damping and local variable damping at the same time. The invention has the advantages that the step damping and the variable damping are realized by a set of multi-stage variable damping sub-assemblies, the structure is compact, and the space is saved.

Description

technical field [0001] The invention relates to a torsional shock absorber matched with a hybrid electric vehicle and a fuel vehicle, in particular to a flywheel shock absorber integrating multi-stage variable damping. Background technique [0002] There are different driving conditions during the operation of a hybrid vehicle, such as idling conditions, driving conditions, and power generation conditions, and different working conditions require corresponding vibration reduction frequencies. [0003] With the continuous improvement of driving comfort requirements during the running of automobiles and the continuous development of hybrid vehicles, it is especially necessary to match a high-performance shock absorber for hybrid vehicles. Although the dual-mass flywheel has good vibration damping performance as a whole, its structure does not have a multi-stage variable damping mechanism with adjustable damping, which cannot better optimize the vibration damping effect of the ...
