Description
Technical Field
The invention relates to a torsion damper matched with a hybrid electric vehicle and an internal combustion engine vehicle, in particular to a flywheel damper integrated with a radial double damper.
Background
Different running conditions exist in the running process of the automobile, such as idling conditions, driving conditions, power generation conditions and the like, and different working conditions need corresponding vibration reduction frequencies respectively. With the increasing demand for driving comfort during the operation of automobiles and the continuous development of hybrid vehicles, it is particularly necessary to match a high-performance shock absorber for the hybrid vehicle. Although the dual-mass flywheel has good vibration damping performance, the structure of the dual-mass flywheel is not provided with an internal vibration damping structure with low rigidity and adjustable damping, and the vibration of an engine under a specific working condition cannot be solved.
The Chinese patent ZL201921991011.5 flywheel damper integrated with a pre-damper discloses a flywheel damper structure integrated with the pre-damper, wherein the pre-damper is low in bearing torque and cannot cover the application requirements of large torque and low rigidity in practical application.
In the chinese patent ZL201520157151.8 flywheel damper, the inner damper and the outer damper are connected in parallel, and the parallel operation is helpful to increase the limit torque, but under the application condition of relatively small torque such as a passenger car, the rotation angle of the parallel operation is limited by the structure and cannot be increased, and the corresponding damping performance is relatively limited. Meanwhile, the inner shock absorber in the patent can only be assembled with four groups of springs due to structural limitation.
This is where the application needs to be focused on.
