Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/093425
Kind Code:
A1
Abstract:
Disclosed is a power transmission device which achieves effective engine breaking and can simplify the structure and control of an automatic transmission device. The power transmission device is provided with an input element (2) to which power from an engine (61) is inputted, a first output element (3) which is arranged on the power transmission path from the input element (2) to the drive wheels (52), a first clutch (10) for blockably transmitting power from the input element (2) to the first output element (3), and a second clutch (20) which transmits power from the first output element (3) to the input element (2) and blocks the transmission of power from the input element (2) to the first output element (3). Because during coasting power is transmitted from the drive wheels (52) to the first output element (3) and is transmitted to the input element (2) via the second clutch (20), the power transmission device can achieve effective engine breaking in coordination with the release of the accelerator pedal, and can simplify the structure and control of an automatic transmission device (62).
