Damper device

摘要

A damper device including an input element to which power from a motor is transmitted; a first elastic body to which power is transmitted from the input element; a first intermediate element to which power is transmitted from the first elastic body; a second elastic body to which power is transmitted from the first intermediate element; a second intermediate element to which power is transmitted from the second elastic body; a third elastic body to which power is transmitted from the second intermediate element; and an output element to which power is transmitted from the third elastic body. The first and second elastic bodies are coil springs, and the third elastic body is an arc spring that is arranged radially inward of the first and second elastic bodies.

1. A damper device comprising:
an input element configured to transmit power from a motor to a first elastic body; the first elastic body configured to transmit power from the input element to a first intermediate element; the first intermediate element configured to transmit power from the first elastic body to a second elastic body; the second elastic body configured to transmit power from the first intermediate element to a second intermediate element; the second intermediate element configured to transmit power from the second elastic body to a third elastic body; the third elastic body configured to transmit power from the second intermediate element to an output element; and the output element to which power is transmitted from the third elastic body, wherein the first and second elastic bodies are straight coil springs, and the third elastic body is an arc spring that is arranged radially inward of the first and second elastic bodies, and the first intermediate element is formed as an annular member, an entire inner surface of the annular member supporting an outer surface of the first elastic body and an outer surface of the second elastic body, the inner surface of the annular member being formed as an annular shape.
