Title:
DAMPER DEVICE
Document Type and Number:
Japanese Patent JP2017166584
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce a size of a device as a whole, in the damper device having at least two torque transmission routes.SOLUTION: First to fourth springs SP11 to SP22 being four kinds of springs paired into two sets are arranged so that attachment radii r11 to r22 being distances from a center shaft CA of a damper device up to axial cores of the first to fourth springs SP11 to SP22 coincide with one another. Then, the first to fourth springs SP11 to SP22 are arranged so that the axial cores are located on the same plane. Furthermore, an intermediate spring SPm is arranged at an external peripheral side of the first to fourth springs SP11 to SP22 so that its axial core is located on the same plane as those of the first to fourth springs SP11 to SP22. By these arrangements, the five kinds of springs can be compactly arranged, and a length of the damper device 10 in an axial direction can be shortened.SELECTED DRAWING: Figure 2
