Title:
DAMPER FOR VEHICLE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/109015
Kind Code:
A1
Abstract:
A damper for a vehicle, and a vehicle. In the damper for a vehicle, a first main damping spring (41) among a plurality of main damping springs only corresponds to a first hub flange (21) and a second main damping spring (42) only corresponds to a second hub flange (22), so that the first main damping spring (41) and the second main damping spring (42) are connected in series during the transmission of torque of the damper. Thus, the total relative rotation angle of the two hub flanges (21, 22) is equal to the sum of the relative rotation angle of the first hub flange (21) relative to side plates (31, 32) and the relative rotation angle of the side plates (31, 32) relative to the second hub flange (22). In addition, a pre-damping spring (9) is provided between the first hub flange (21) and a third hub flange (82) positioned on the radially inner side thereof, or between the second hub flange (22) and a hub core positioned on the radially inner side thereof. The present damper for a vehicle features a simple structure and low costs, and is able to effectively reduce torsional rigidity, and thus the damper has an excellent damping effect whether during engine normal working or during engine idling rotation.
