Description

Technical Field [0001] The present invention relates to a damper clutch for automated manual transmission,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper clutch device for an automatic manual transmission, and more particularly, to a damper clutch device for an automatic manual transmission, in which a plurality of power transmission paths from an engine to a transmission And the other transmission path is limited to the operation of the damper clutch so that the power can be transmitted to the transmission so that the noise and shock generated during the transmission of the low speed section can be minimized. To a damper clutch device.

Generally, an automatic manual transmission (AMT) has been developed in order to facilitate the driver's convenience by automatically implementing the shift operation of a conventional manual transmission, by synchronizing the synchromesh mechanism through the operation of the actuator.

Since such an automatic manual transmission utilizes the gear train of a conventional manual transmission as it is, the power transmission path from the engine to the transmission via the clutch is set to a single path. That is, the power transmitted from the engine to the input side of the transmission via the clutch is provided through one input shaft.

As a result, in the conventional automatic manual transmission, when gear shifting is performed in a low speed section during running, the gear ratio is large, which causes a problem of noise accompanied with a shift shock. Particularly, in the low-speed running region, the impact and noise involved in shifting not only deteriorates the durability performance of the transmission but also results in a significant decrease in the commerciality due to the deterioration of the customer's satisfaction. .
